Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a geared motor in which a motor including a motor, a reduction gear, and a motor frame that covers the outer periphery of the reduction gear and the motor and the reduction gear are integrated.
[0002]
[Prior art]
Conventionally, a lead wire drawing method in a geared motor in which a reduction gear and a motor unit as shown in FIG. 7 are integrated is known.
[0003]
FIG. 7 is a left and right side view and a front view of a geared motor 700 configured integrally with a motor 702 and a speed reducer 701.
[0004]
The outer circumference of the geared motor 700 is covered with a motor frame 710 in order to protect the inside of the geared motor 700 from an impact or the like. On the side surface 710 a of the motor frame 710, an outlet 720 for drawing out a motor lead wire 730 for driving the motor in the geared motor 700 is formed.
[0005]
[Problems to be solved by the invention]
However, in the conventional geared motor 700 as shown in FIG. 7, the outlet 720 of the motor lead wire 730 is formed only in one direction from the motor frame side surface 710 a, and therefore, depending on the direction of the outlet 720 of the motor lead wire 730. However, there has been a problem that installation of the geared motor 700 may be difficult or impossible.
[0006]
For example, in order to solve this problem, it is conceivable to change the pull-out direction of the outlet 720 formed on the side surface 710a of the motor frame 710. However, a new motor frame is prepared and the required pull-out direction is prepared. Since the design needs to be redesigned so as to meet the requirements, it has been a cause of increased costs and increased types of components.
[0007]
The present invention has been made in view of such a conventional problem. The motor frame is divided into a main frame and a sub-frame, and the sub-frame is rotated to thereby draw out the motor lead wire. It is an object of the present invention to provide a geared motor that can be selected in multiple directions and can be installed in a wide range.
[0008]
[Means for Solving the Problems]
The present invention relates to a geared motor in which a motor including a motor, a speed reducer, and a motor frame that covers the outer periphery of the motor and the speed reducer are integrated, and the motor frame is connected to the motor and the speed reducer. A main frame that covers the main body side of the main frame, and an outlet for drawing out a motor lead wire for driving the motor disposed at the motor side end of the main frame at a position away from the axis of the motor shaft of the motor And having a structure that can be divided into sub-frames, and forming a mounting hole in each of the main frame and the sub-frame so that the frames can be connected to each other, and the sub-frame to the main frame, While the main frame is attached to the counterpart machine, the sub frame and the main frame are rotated at least once while the main frame is rotated 0 to 90 degrees. By each of the mounting holes of the over arm has to match, in which the above-mentioned problems are eliminated.
[0009]
By doing in this way, the outlet of the motor lead wire can be opened from multiple directions (at least four directions) with the main frame (that is, the motor and the speed reducer housed in the main frame) attached to the counterpart machine. The environment where the geared motor can be installed can be widened.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
First, the internal configuration of the geared motor according to the present embodiment will be described with reference to FIGS. FIG. 4 is a front sectional view of the geared motor according to the present embodiment, and FIG. 5 is a developed flat sectional view.
[0012]
4 and 5, the geared motor 100 is mainly composed of a motor 102 and a speed reducer 101 as in the prior art. The motor 102 includes a motor shaft 141 that is a shaft of the motor, and a hypoid pinion 160 is formed at the tip of the motor shaft 141.
[0013]
The speed reducer 101 mainly includes a first pinion shaft 150, a second pinion shaft 152, an output shaft 154, and a plurality of gears incorporated therein, which are orthogonal to the motor shaft 141 in plan view.
[0014]
A first gear 122 and a second gear 124 that engage with the hypoid pinion 160 are incorporated in the first pinion shaft 150. A third gear 126 that meshes with the second gear 124 and a fourth gear 128 are incorporated in the second pinion shaft 152. Further, a fifth gear 132 that meshes with the fourth gear 128 is incorporated in the output shaft 154.
[0015]
An external view of a geared motor 100 constituted by such gears and shafts is shown in FIG.
[0016]
In FIG. 1, the configuration of the geared motor 100 has the same or similar portions as the configuration of the geared motor 700 of FIG. 7 described in “Prior Art”, and therefore the last two digits are the same for the (identical or similar) portions. Numbers will be added, and clear overlapping explanations will be omitted.
[0017]
FIG. 1 shows a geared motor 100 including a reduction gear 101 and a motor frame 110 that covers the outer periphery of the motor 102. The motor frame 110 can be divided into a main frame 111 that covers the main body side of the motor 102 and the speed reducer 101, and a subframe 112 that has an outlet 120 for pulling out a motor lead wire 130 for driving the motor 102. It has a structure. The outlet 120 is formed on the side surface 112 a of the subframe 112. The formation structure itself of the outlet 120 is the same as that of the conventional technique.
[0018]
The main frame 110 is formed so that its cross-sectional shape (the shape in the direction Y perpendicular to the axial direction X of the motor shaft 141 (see FIGS. 4 and 5)) is a substantially quadrangular shape. On the other hand, the sub-frame 112 has a shape such that the main frame 111 side exactly matches the main frame 111, and the vertical and horizontal shapes are symmetrical as shown in FIG.
[0019]
In the present embodiment, mounting holes 140A to 140H and 140a to 140h in which the respective frames can be connected by screws 170 are formed in the main frame 111 and the sub frame 112 having such shapes. In FIG. 1, the mounting holes 140 </ b> A to 140 </ b> H on the main frame 111 side do not penetrate the main frame 111, but may penetrate.
[0020]
Here, in the present embodiment, each of the attachment holes 140a to 140h and 140A to 140H of the subframe and the main frame 111 is at least 1 while the subframe 112 is rotated from 0 degrees to 90 degrees with respect to the main frame 111. The times are formed to match. Specifically, in FIG. 1, the subframe 112 has a vertically and horizontally symmetrical shape, and the mounting holes 140 a to 140 h of the subframe 112 completely coincide with the mounting holes 140 A to 140 H of the main frame 111. It is formed as follows. Therefore, every time the sub frame 112 is rotated 90 degrees with respect to the main frame 111, the mounting holes 140a to 140h of the sub frame 112 and the mounting holes (140A to 140H) of the main frame 111 coincide.
[0021]
With such a structure, the outlet 120 formed on the side surface 111a of the subframe 111 is also moved (rotated in order of 90 degrees, 180 degrees, 270 degrees 360 degrees, ...) in the same manner as the subframe 112 rotates. ).
[0022]
The present invention makes use of this, for example, as shown in FIGS. 2 and 3, where the outer periphery of the motor frame 111 is surrounded by an ineffective space (hereinafter referred to as a mating member B) such as a wall or a machine in multiple directions. This is especially true when it has to be installed.
[0023]
In other words, even if the subframe 112 is rotated with respect to the main frame 111 (90 degrees in the illustrated example), the mounting holes of the subframe 112 and the main frame 111 match, so the subframe 112 is rotated. This (shifting) makes it possible to shift the outlet 120 to a position where the mating members B and B1 (see FIG. 3) are not present (position where the motor lead 130 can be easily pulled out).
[0024]
In this way, the outlet 120 of the motor lead 130 can be selected (in this case, from four directions 120, 120a, 120b, and 120c), and the environment in which the geared motor 100 can be installed can be widened.
[0025]
By the way, the geared motor 100 described above has a configuration in which the mounting holes of the main frame 111 and the sub frame 112 coincide with each other by rotating the sub frame 112 by 90 degrees with respect to the main frame 111. The invention is not limited to only 90 degrees.
[0026]
That is, it is an example that the mounting holes 140a to 140h and 140A to 140H coincide with each other by 90 degrees. As described above, the present invention rotates the subframe 112 with respect to the main frame 111 by 0 degrees to 90 degrees. The mounting holes 140a to 140h are made to coincide with each other at least once.
[0027]
Specifically, for example, when the mounting holes are formed so as to match every 30 degrees, the outlet of the motor lead wire 130 can be selected from 12 types (by 360 degrees / 30 degrees). For example, when the mounting holes coincide every 45 degrees, the outlet of the motor lead wire 130 can be selected from eight ways. In these configurations, for example, the mounting holes may be arranged equally in the circumferential direction every 30 degrees or every 45 degrees.
[0028]
In this way, when the motor frame 110 is installed in a place where the outer periphery of the motor frame 110 is covered (enclosed) (as in FIGS. 2 and 3), The installation location is not limited by the direction or the installation is not disabled, and the degree of installation freedom can be increased.
[0029]
Moreover, by doing in this way, it is not necessary to take the method of preparing separately the frame etc. which provided the outlet 120 in multiple directions, and it can also be restrained at low cost.
[0030]
For reference, a waterproof geared motor is shown in FIG.
[0031]
Since the configuration of the geared motor 600 is the same as or similar to that of the above-described configuration of the geared motor 100 of FIG. 1, the last two digits are given the same numbers, and an obvious overlapping description is omitted. In the same manner as described above, the motor frame 610 has a main frame 611 that covers the main body side of the motor 602 and the speed reducer 601, and an outlet 620 for pulling out a motor lead wire 630 for driving the motor 601. Since it is divided into the sub-frame 612 and the mounting holes 640A to 640H and 640a to 640h are formed in the same manner as in the above embodiment, the predetermined effect of the present invention can be obtained.
[0032]
Further, in FIGS. 1 and 2, the mounting holes are formed in the vicinity of each corner of the sub-frame 112 at two positions (one pair). As long as at least one of them is fixed, the other screw can be omitted as shown in FIG.
[0033]
In the present embodiment, the motor frame 110 itself has been described by taking a substantially square shape as an example. However, the shape is not particularly limited. Further, the number of screws, the number of mounting holes, the shape, and the like are not limited. In short, by rotating the subframe with respect to the main frame, the direction of the outlet 120 of the motor lead 130 can be changed every 90 degrees or less, and the structure can be selected from multiple directions.
[0034]
【The invention's effect】
As described above, according to the present invention, it is possible to select the direction in which the motor lead wire is pulled out in multiple directions within a range of 90 degrees or less without increasing the number of types of motor frames, and a wide range of environments where a geared motor can be installed. Can be made possible.
