Description

  The present invention relates to a hypoid gear measurement device that measures torque transmission characteristics of a hypoid gear that includes a pinion gear and a ring gear that mesh with each other.

  Conventionally, rotation angle transmission error generated by a hypoid gear while changing the rotation speed and load torque using a rotary encoder built in the pinion main shaft and gear main shaft as a detector with the same rotation and torque as the actual vehicle. Is known from a rotary encoder pulse, and a hypoid gear measurement device that performs an order ratio analysis using an FFT analyzer is known (see, for example, Non-Patent Document 1).

  FIG. 1 is a diagram showing a configuration of the hypoid gear measurement device 2.

  The configuration of a conventional hypoid gear measurement device 2 will be briefly described with reference to FIG.

  A pinion gear 201 and a ring gear 202 constituting a hypoid gear are respectively attached to a pinion main shaft 21 and a gear main shaft 22 having gear holders included in the hypoid gear measurement device 2 shown in FIG.

  In the hypoid measuring device 2 of FIG. 1, a pinion gear 201 and a ring gear 202 are mounted on the pinion main shaft 21 and the gear main shaft 22, respectively, so that the respective gears can be engaged with each other. And a slide mechanism SA that slides along the direction in which the rotation axis on the pinion main shaft 21 extends (hereinafter referred to as H-axis), and the ring gear 202 along the direction in which the rotation axis on the gear main shaft 22 extends (hereinafter referred to as G-axis). A slide mechanism SB that slides and a slide mechanism SC that slides the ring gear 202 along a direction orthogonal to the G axis (hereinafter referred to as V axis) are provided.

  For this reason, a spline gear is built in the rotation shaft of the pinion main shaft 21 and the gear main shaft 22 to which the pinion gear 201 and the ring gear 202 are connected, and the pinion main shaft 21 and the gear main shaft 22 are arranged along the H axis and the G axis. Even if it slides horizontally, the rotation and torque are transmitted reliably. Then, an AC servo motor is connected to the ends of the rotation shafts via pulleys and belts so that rotation and torque are separately applied to both the pinion gear and the ring gear.

  The slide mechanism SA that slides the pinion gear 201 along the H axis includes a rigid bed 20, a slide base 210 fixed on the bed 20, and a slide table 211 that slides on the slide base 210. ing.

  After the pinion gear 201 is connected to the pinion main shaft 21 on the slide table 211 in FIG. 1 by a measurement person, the pinion shaft 21 is slid along the H axis together with the pinion gear 201 to move the pinion gear 201 in the H-axis direction. The position is adjusted.

  The slide mechanism SB that slides the ring gear 202 along the G axis includes a slide base 220 fixed on the bed 20 and a slide table 221 that slides on the slide base 220.

The ring gear 20 is attached to the gear spindle 22 on the slide table 221 in FIG.
After the two are coupled, the position of the ring gear 202 in the G-axis direction is adjusted by sliding the slide table 221 along with the ring gear 202 along the G-axis.

  Further, a slide mechanism SC for sliding the ring gear 202 along the V-axis direction is provided on the slide table 221 that slides the ring gear 202 along the G-axis. The slide mechanism SC includes a column 222 coupled to a slide table 221 that slides along the V-axis direction, and a slide table 223 that slides along the column 222.

  After the ring gear 202 is connected to the gear main shaft 22 on the slide table 221 in FIG. 1 by the person in charge of measurement, the slide table 223 is slid along the V axis together with the ring gear 202 to thereby move the ring gear 202 in the V axis direction. The position of is adjusted.

  That is, the person in charge of measurement uses these slide mechanisms SA, SB, SC to mesh the pinion gear 201 and the ring gear 202 mounted on the pinion main shaft 21 and the gear main shaft 22 and then the transmission characteristics of the hypoid gear. Measurement will be performed.

  FIG. 2 is a view of the hypoid measuring device 2 of FIG. 1 as viewed from above. FIG. 2 shows a drive unit for applying a load to the hypoid gear described above in addition to the configuration of FIG.

  An AC servo motor M1 is connected to the drive unit that applies a load to the pinion main shaft 21 via pulleys P1 and P2 and a belt V1, and a drive unit that applies a load to the gear main shaft 22 is connected via pulleys P3 and P4 and a belt V2. An AC servo motor M2 is connected. As described above, when the position of each slide table 211, 221, 223 is adjusted and the pinion gear 201 (see FIG. 1) and the ring gear 202 (see FIG. 1) mesh with each other, the motor M1 of the pinion shaft 21 and the gear shaft 22 are engaged. Since the motor M2 is connected to the hypoid gear via the hypoid gear, a load can be applied to the hypoid gear using both AC servomotors M1 and M2.

  When measurement is started by applying rotation and torque similar to those of the actual vehicle to the hypoid gears by the AC servo motors M1 and M2, rotary encoders (not shown) built in both the pinion main shaft 21 and the gear main shaft 22 are started. ) Is transmitted to an FFT analyzer (not shown), and the FFT analyzer analyzes what the transmission characteristics of the hypoid gear are.

  By the way, the hypoid measuring device 2 shown in FIG. 2 so far has mainly aimed to measure the torque range (up to 600 Nm) of cruise / slow acceleration of small / medium-sized vehicles. It is necessary to measure the transmission characteristics of a hypoid gear by applying a high load torque, which is an acceleration torque region (˜1800 Nm), to the hypoid gear.

  However, there is no production record of a hypoid measuring device that can apply a high load torque in Japan, and there is no production example including overseas. In such a hypoid measuring device capable of applying a high load torque, the hypoid measuring device itself is not deformed as much as possible by a reaction force from the hypoid gear when a high load torque is applied to the hypoid gear. It is necessary to be.

  However, since the hypoid measuring apparatus 2 in FIG. 1 has only a measurement range up to 600 Nm as described above, there is a possibility that a large deformation will occur if a high load torque up to 1800 Nm is applied.

  Here, what kind of deformation may occur when a high load torque is applied to the hypoid measuring device 2 of FIG. 1 will be described.

  FIG. 3 is a side view of the first main shaft 21 side cut along the V axis and viewed from the side. FIG. 4 shows the second main shaft 22 side cut along the V axis and cut. It is the figure which looked at the done surface from the side.

  Considering applying a higher load torque to the hypoid gear than before, the pinion main shaft 21 and the gear main shaft 22 that connect the hypoid gear, and the slide bases 211 and 220 and the column 222 to which they are connected are reduced in deformation. Higher rigidity is required to suppress.

  However, in the current hypoid gear measuring device 2 shown in FIGS. 3 and 4, spaces SP1, SP2, and SP3 are provided inside the pinion main shaft 21 and the slide bases 210 and 220, and the guide portions 2110 and 21 of the slide tables 211 and 221 are provided. The thickness of the connecting portion 21A between 2210 and the pinion main shaft 21 and the slide table 211 and the connecting portions 210A and 220A between the slide bases 210 and 220 and the bed 10 are thin.

  In other words, the rigidity of the connecting portion of the pinion main shaft 21, slide tables 211, 221 and slide bases 210, 220 is low, and when a high load torque of 1800 Nm is applied to the current hypoid gear measuring device 2 in FIG. There is a possibility that large deformation may occur due to the reaction force from the gears around the space portions SP1 to SP3 of the bases 211 and 220, around the guide portions 2110 and 2210, and around the thin portions 21A, 210A and 220A connecting the respective portions. is there.

  The column 222 is placed on the slide base 221, and the gear main shaft 22 is set at a distance HA away from the bed 20 which is a rigid body. Therefore, the gear reaction force is amplified to a greater force in the guide portion 2230 of the slide table 223, causing the guide portion 2230 to be greatly deformed.

  Thus, if the hypoid measuring device 2 is deformed during the measurement, the meshing position of the hypoid is shifted and the measurement cannot be performed accurately.

FIG. 8 is a diagram showing a state when the engagement of the ring gear 101 and the pinion gear 102 is similarly adjusted by the slide mechanism SC1 in the V-axis direction.

  The configuration will be described with reference to FIG.

  First, as shown in FIG. 5, the hypoid gear measurement device 1 includes a bed 10 that functions as a rigid body. A column 11 is erected on the bed 10, and the column 11 is fixed to the bed 10 so as not to move with a number of bolts (not shown). In this way, the column 11 is firmly connected to the bed 10 and the column 11 and the bed 10 are made into an integral structure, so that these serve as a rigid body.

  The side surface 110 of the column 11 includes a slide mechanism SA1 that slides the pinion main shaft 13 in the H-axis direction and a slide mechanism SC1 that slides in the V-axis direction.

  The slide mechanism SB1 that slides the gear main shaft 15 in the G-axis direction is configured on a slide base 14 that is firmly connected to the bed 10 that functions as a rigid body.

  The configuration of the slide mechanism SA1, the configuration of the slide mechanism SB1, and the configuration of the slide mechanism SC1 will be described with reference to FIGS.

  First, the configuration of the slide mechanism SC1 for sliding the pinion main shaft 13 in the V-axis direction will be described.

  A slide mechanism SC1 for sliding the pinion main shaft 13 in FIG. 8 in the V-axis direction is constituted by a slide table 12 as shown in FIG. 5, and the slide table 12 is connected to the column 11 so as to be movable in the V-axis direction. ing. The slide table 12 has a so-called slide guide structure that slides in contact with the side surface 110 of the column 11.

  The slide table 12 slides up and down, that is, in the V-axis direction when a clamp nut of a cylinder (described later) attached to the column 11 is in an unclamped state where it does not engage with the engaging portion ENG1, and clamps the tip of the cylinder. When the nut is in a clamped state where the nut engages with the engaging portion ENG1 of the slide table 12, the nut is fixed to the column 11 so as not to move.

  In this way, the slide table 12 is fixed to the column 11 which can be regarded as a rigid body so as not to move, so that the slide table 12 after being clamped to the column 11 composed of blocks also has a function as a rigid body. ing.

Further, the second side surface 122 of the slide table 12 opposite to the first side surface 121 on the column 11 side has a so-called slip guide structure 123 that is in contact with the side surface of the main shaft 13. The second side surface 122 of the slide table 12 is also provided with a second engagement portion ENG2 that is different from the engagement portion ENG1, and the pinion main shaft 13 is a cylinder attached to the pinion main shaft 13 ( When the clamp nut (not shown) is in an unclamped state where it does not engage with the second engagement portion ENG2, it moves in the H-axis direction as shown in FIG. 6, and the clamp nut is engaged with the second engagement portion ENG2. When in a clamped state, the slide table 12 is fixed so as not to move.

  In this way, the pinion main shaft 13 is fixed to the slide table 12 fixed to the column so as not to move, so that the pinion main shaft 13 as well as the slide table 12 has a function as a rigid body.

  On the other hand, the gear main shaft 15 is provided with a slide base 14 that constitutes a slide mechanism SB1 that slides the gear main shaft 15 in the G-axis direction. A cylinder is attached to the gear main shaft 15 similarly to the pinion main shaft, and the slide base 14 is provided with a third engagement portion (described later) with which a clamp nut at the tip of the cylinder is engaged. . When the clamp nut of the cylinder is in an unclamped state where it does not engage with the third engaging portion, the gear spindle 15 moves in the G direction as shown in FIG. The gear main shaft 15 is fixed to the slide base 14 so as not to be movable when it is in a clamped state in which the engagement portion 3 is engaged.

  Thus, the slide table 12 is clamped to the column 11 by the clamping mechanism, the pinion main shaft 13 is clamped to the slide table 12, and the gear main shaft 15 is further clamped to the slide base 14, and then the pinion main shaft 13 and the gear main shaft 15 are provided. The rotation and torque from the motors M3 and M4 are applied to a rotation receiving portion (described later) at the end of the rotation shaft, and the rotation of both rotation shafts starts measurement of gear transmission characteristics.

  FIG. 9 is a view of the hypoid measurement device 1 of FIG. 5 as viewed from above. FIG. 9 shows a configuration of a drive unit for applying rotation to the pinion main shaft 13 and the gear main shaft 15.

  In the conventional hypoid measuring device 2 of FIG. 2, since the load torque was not so large, the motor drive unit including the belt reducer could be built in the hypoid measuring device 2, but in this embodiment, FIG. As shown in the figure, the motors M3 and M4 are arranged outside the hypoid measuring device 1 because the motor unit including the belt speed reducer A is large, and the rotation and torque from the motors M3 and M4 by the belts V3, V4 and V5. Is transmitted to the rotation receiving portion R1 provided at the end of the rotation shaft of the pinion main shaft 13 and the rotation receiving portion R2 provided at the end of the rotation shaft of the gear main shaft 15.

  After the pinion gear 101 and the ring gear 102 are thus meshed, a high load torque reaching 1800 Nm is applied to the hypoid gear from the motors M3 and M4 as described above, and measurement is performed.

  Here, conventionally, as described with reference to FIGS. 1 to 4, a space is provided in the pinion main shaft 21 and the slide base 210, or the column 222 is placed on the slide base 221 and can be regarded as the only rigid body. Since the ring gear 202 is disposed at a distant place, the rigidity of the hypoid measuring device is lowered and there is a problem that a large deformation may occur.

  Therefore, how this conventional problem is solved in the present invention will be described.

  FIG. 10 is a diagram illustrating a configuration on the gear main shaft 15 side, and FIG. 11 is a diagram illustrating a configuration on the pinion main shaft 13 side.

As shown in FIGS. In the present embodiment, the thin portion as described with reference to FIGS. 2 and 3 is abolished, and the entire portion is configured with a thick thickness, thereby improving the rigidity.

  Further, as shown in FIG. 10A, the gear main shaft 15 is arranged at a short distance H1 from the slide base 14 fixed on the bed 10 serving as the first block according to the present invention. The clamping force shown in FIG. 10B is used to clamp the slide base 14 to improve the rigidity.

  Further, as shown in FIG. 11, the pinion main shaft 13 is arranged at a short distance H2 from the first block 11 that can be regarded as a rigid body like the bed 10 and is clamped by a clamping mechanism, thereby improving the rigidity. ing. In FIG. 11, the third block 16 is provided and the pinion main shaft 13 is tilted during the unclamped state, and the pinion main shaft 13 is moved by using the third block 16 and the gibb g1 and the gibb g2. It is also shown that accuracy was ensured when sliding.

  In this way, thin parts such as the conventional spindle and slide table are eliminated, the strength of each member is improved, a block that can be regarded as a rigid body is placed near the gear, and each spindle is clamped to that block Further improvement in rigidity is achieved.

  Here, the structure of the clamp mechanism provided for the purpose of improving the rigidity during the measurement of the transmission characteristics of the hypoid gear will be described.

  In FIG. 12, after the slide table 12, the pinion main shaft 13 and the gear main shaft 15 are slid and the position adjustment is completed, the slide table 12, the slide table 14 and the pinion main shaft 13 provided in each adjustment mechanism SA, SB and SC cannot be moved. It is a figure which shows the structure of the clamp mechanism for making it.

  FIG. 12A shows the configuration of the clamp mechanism including the third engagement portion ENG3 and the second engagement portion ENG2 shown in FIGS. FIG. 12B shows the configuration of the clamp mechanism including the first engagement portion ENG1 shown in FIG.

  As shown in FIG. 12A, a clamp bolt CL is attached to the cylinder rod SL1, and the movement of the cylinder rod SL1 is controlled by hydraulic pressure. When hydraulic pressure is applied to the supply port A, the clamp bolt CL and further the clamp nut CN1 slide to the right in the drawing together with the cylinder rod SL1, and the clamp nut CN1 engages with the engagement portion ENG2 in the slide table 12 to pinion main shaft. 13 is firmly fixed to the slide table 12. When hydraulic pressure is applied to the supply port B, the clamp bolt CL and further the clamp nut CN1 move to the left together with the cylinder rod SL1, the clamp nut CN1 is removed from the engaging portion ENG2 of the slide table 12, and the pinion main shaft 13 slides. Unclamped from the table 12. In the present embodiment, cylinders are arranged at a total of six locations on the front and lower front, middle, and back sides of the pinion main shaft 13 shown in FIG. 11 so that the pinion main shaft 13 can be securely clamped to the slide table 12. ing.

  On the other hand, if the configuration of FIG. 12A is adopted for the slide table 12 on the pinion main shaft 13 side, the hydraulic pressure also drops when the power is turned off, so that the clamping force decreases with time and the slide table 12 falls by its own weight. Therefore, on the pinion main shaft 13 side, a disc spring SPR is provided as a clamping mechanism as shown in FIG. 12B so that the slide table 12 does not fall in the direction of its own weight. In the configuration of FIG. 12B, when the cylinder rod SL1 is brought into the unclamped state, the cylinder rod SL1 is slid by generating a force against the spring bias of the disc spring by applying hydraulic pressure to the supply port B. It is.

  With this configuration, even if the cylinder rod is automatically slid, the spindle is automatically clamped to each block that can be regarded as a rigid body after the spindle is slid, and the spindle and each block are integrated. It is possible to reduce the rigidity of each main shaft as much as possible.

  As described above, a hypoid measuring device capable of measuring the transmission characteristics of a hypoid gear in a stable state when a high load torque is applied to the hypoid gear is realized.

  In the present embodiment, the pinion shaft is described as the first main shaft and the gear shaft is described as the second main shaft. However, the gear shaft may be the second main shaft and the pinion shaft may be the first main shaft. .
