Description
Technical field
The present invention relates to the spring torque limiter that in office equipment such as printer, duplicating machine, uses, particularly relate to the countermeasure that prevents of the generation that prevents helical spring vibration or abnormal sound.
Background technique
As the known spring torque limiter that in office equipment etc., uses in the past, as shown in Figure 5, constitute, that is: outer ring element 41 by following each member; Inner ring 43, it is inserted into the inside of outer ring element 41, and can be bearing in the relative rotation on the shaft sleeve part 42 of an end of outer ring element 41; Helical spring 44, it is installed on the outer diametric plane of this inner ring 43 with needed magnitude of interference; With lid member 49, the other end of its ring element 41 outside described is fixed on its aperture surface by chimeric, and seals between the outer diametric plane of this aperture surface and inner ring 43, and inner ring 43 is supported in rotation freely.Described helical spring 44 has large-diameter portion 44a and minor diameter part 44b, and this minor diameter part 44b is fastened on the outer diametric plane of described inner ring 43 with needed magnitude of interference.On the end of this minor diameter part 44b, be provided with axially crooked hook 45, and it is engaged with the shaft sleeve part 42 of described outer ring element 41.And, on the end of large-diameter portion 44a, also be provided with axially crooked hook 46, and make it engage (with reference to patent documentation 1) with lid member 49.
Above-mentioned torque limiter 40 is if make helical spring 44 to observe the sense of rotation identical with its curl direction (the right curl direction the figure) (the right rotation direction from the observation of hook 45 sides among the figure) rotation from hook 45 sides by the inner ring 43 and the relative rotation of outer ring element 41, then produce the hole enlargement effect at minor diameter part 44b, and produce a certain size moment of torsion, promptly produce the torque value of regulation.Produce to the counterrotating situation of described opposite direction under, produce the undergauge effect at minor diameter part 44b, make that inner ring 43 is locked, therefore, can not bring into play function in this case as torque limiter.That is, produce as the effect of folk prescription to torque limiter.
But, described torque limiter produce based on inner ring 43 and outside initial stage of counterrotating moment of torsion of ring element 41, helical spring 44 produces local deflection 52 (with reference to Fig. 6) near hook 45, during the whole hole enlargement of arriving this deflection disappearance and minor diameter part 44b, inner ring 43 or outer ring element 41 are in the state that can not rotate.That is, produce from being input to of rotating force moment of torsion during generation time postpone, promptly produce gap (back lash), produce the problem of deviation in the sequential that therefore exists moment of torsion to transmit.
On the other hand, there is large-diameter portion 44a in the helical spring 44 of described torque limiter, and on two end part, there is an axially crooked hook 45,46, therefore, not only hindered the miniaturization of torque limiter, and the operation that the time need aim at the card complex hole insertion hook of outer ring element etc. in assembling, this operation also becomes the main cause that influences operability.
In order to address these problems, can consider to adopt the structure shown in Fig. 7 (a) and (b), that is, use the spring in single footpath, and its two end part are formed keep spiral-shaped cut end (to be called straight end 45 ', 46 ' as helical spring 44.), and make these ends 45 ', 46 ' withstand on the outer ring element teat 53 on the aperture surface that is located at outer ring element 41 respectively respectively and be located at the side (with reference to Fig. 7 (b)) of the lid member teat 54 that covers on the member 49.
But, under situation about such helical spring 44 being installed in certain magnitude of interference on the inner ring 43, as shown in Figure 8, though spiral part 56 is by hole enlargement slightly, radius of curvature increases, because straight end 45 ' and near part thereof, it is the radius of curvature when keeping the little free state of radius of curvature than spiral part 56 and crooked state is crimped onto on the inner ring 43, and its front end withstands on the outer diametric plane of inner ring 43, and therefore, the rotation that can produce inner ring 43 forms the bad phenomenon of disturbing.In addition, the straight end 46 ' about the opposing party also can produce same phenomenon.
In order to solve above problem, claimant of the present invention has proposed before this about the patent application of the modified model torque limiter that has improved described helical spring 44 (special hope 2004-362804 number, special hope 2005-36352 number).The helical spring 44 that in this modified model torque limiter, uses, shown in Fig. 9 (a)～(c), near two end part, be provided with the circular arc part 57 that under free state, becomes the radius of curvature bigger than other spiral parts 56,58, and the size of this radius of curvature is set at, at this helical spring 44 by hole enlargement, and at the state on the inner ring 43 of being installed in needed magnitude of interference (with reference to the single-point line of Fig. 9 (b), Fig. 9 (c)) under, practically identical with the radius of curvature of spiral part 56, and, a side or the both sides of the aperture surface of ring element 41 or lid member 49 are provided with three restriction teats 59 outside.
Above-mentioned modified model torque limiter is not owing to be provided with hook at two end part, and formed the shape on the side that each front-end face 57 ', 58 ' that makes circular arc part 57,58 withstands on outer ring element teat (omit diagram), lid member teat 54 respectively, so be suitable for miniaturization.And, owing to have circular arc part 57,58, so, can play following effect, that is, the interference of front-end face 57 ', 58 ' can either be prevented, and, the gap can also be suppressed to produce by utilizing the generation of the local deflection of restriction teat 59 inhibition to inner ring 43.
[patent documentation 1] spy opens flat 8-270673 communique (" embodiment ", Fig. 1, Fig. 2)
, in the spring torque limiter, the change based on the friction factor of the slip surface between helical spring and the inner ring can produce helical spring vibration, and this vibration is amplified by helical spring, thereby causes producing abnormal sound sometimes.Particularly when low speed rotation, owing to be not easy to form oil film, thus be easy to generate the change of friction factor, thereby be easy to generate abnormal sound.Described abnormal sound is a kind of offending noise for the user of office equipment.Though exist by adopting lubricating system to stablize the method that friction factor suppresses to vibrate, but in recent years, problem in so-called chemical erosion enjoys in the actual life of attention, owing to the additive that can add in the crude oil is restricted, so can not constitute countermeasure sufficiently.Therefore, need to adopt mechanical method to constitute the mechanism of the generation that prevents generation of vibration, abnormal sound.

Forming on the part of this inner ring support 8 and the shaft sleeve part interior edge face 11 of the end difference of described aperture surface 6, be provided with outer ring element teat 12 (with reference to Fig. 3 (a)).The size of integral width that should outer ring element teat 12 be set to the footpath direction of the described shaft sleeve part interior edge face 11 of perforation, and near the outer diametric plane of inner ring 2.In addition, its height (axle direction length) forms the sectional dimension of being a bit larger tham the wire rod that constitutes helical spring 4, and can abut to the front-end face 33 ' of this helical spring 4, and does not form and can form the size of disturbing to second part of enclosing of helical spring 4.
Described outer ring element teat 12 has axial two sides, wherein with a side's of the front-end face 33 ' butt of helical spring 4 side 12a (with reference to Fig. 3 (a)), reference line L1 with respect to the radial direction of the center O by outer ring element 1 only is certain tiltangle, and is oblique to a square neck that has this front-end face 33 '.Described tiltangle be set to can be between side 12a and inner ring 2 front-end face 33 ' of interlock helical spring 4, the enough angles that stop its radius vector direction to move.
In addition, on the part near the open end of described aperture surface 6, be provided with the engagement groove 13 of circumferencial direction.In addition, on the outside of shaft sleeve part 5 side ends, be provided with engaging protrusion 14 at roller etc.
Outside described on the aperture surface 6 of ring element 1,, on three positions of circumferencial direction, be provided with restriction teat 28 from described shaft sleeve part interior edge face 11 half scope of about this aperture surface 6 of the open end face side of ring element 1 outward.The interval of the circumferencial direction of restriction teat 28 comprises described outer ring element teat 12, is about 1/4th of complete cycle.Each interior edge face 29 that limits teat 28 forms the conical surface that forward end becomes big footpath.And shown in Fig. 3 (a), (c), each inner face that limits teat 28 forms the arc surface of the inscribe circle belong to radius R (width+δ of the line of the radius+helical spring 4 of R=inner ring 2, wherein, δ is a helical spring 4 and the gap of restriction teat 28).
In addition, the inner face at lid member 3 is provided with and covers member teat 18 (with reference to Fig. 2, Fig. 3 (b)).The height of this lid member teat 18 (axle direction length) is set to, and is bigger slightly than the sectional dimension of the wire rod that constitutes helical spring 4, can abut to the size of the front-end face 34 ' of this helical spring 4, but can not disturb the part of second circle of helical spring 4.And the height of footpath direction is set to the outer diametric plane near inner ring 2.
Shown in Fig. 3 (b), described lid member teat 18 has axial two sides, but wherein with a side's of the opposing party's of helical spring 4 front-end face 34 ' butt side 18a, reference line L1 with respect to the radial direction of the center O by outer ring element 1 only is certain tiltangle, and is oblique to a square neck that has this front-end face 34 '.Described tiltangle be set to can be between side 18a and inner ring 2 front-end face 34 ' of interlock helical spring 4, the enough angles that stop its radius vector direction to move thus.
In addition, at the inner face of lid member 3, three positions in a circumferential direction are provided with the restriction teat 31 of only about half of length of the axle direction length of the aperture surface 6 that is equivalent to outer ring element 1.The interval of the circumferencial direction of restriction teat 31 comprises described lid member teat 18, is about 1/4th of complete cycle.Each interior edge face 32 that limits teat 31 forms the conical surface that forward end becomes path.And each inner face that limits teat 31 forms the arc surface (with reference to Fig. 3 (b), (c)) belong to the inscribe circle of the size of described restriction teat 28 same radius R.
Shown in Fig. 2, Fig. 4 (a), helical spring 4 is to use steel wire rod, and (situation among the figure is square wire rod, but also can be circular wire rod.) twined the helical spring in the single footpath of the regulation number of turns.Under the free state before being installed in inner ring 2, two end part are straight end basically, but in the scope from the end to about 1/2nd circles, form the circular arc part 33,34 (with reference to Fig. 4 (a)) with radius of curvature bigger than other spiral parts this moment.The internal diameter of spiral part 4a except these circular arc part 33,34 since form slightly littler than the external diameter of described inner ring 2, so when it being entrenched on the inner ring 2, promptly being installed into and having certain magnitude of interference.
When being installed in inner ring 2 on certain magnitude of interference helical spring 4, helical spring 4 is by hole enlargements slightly, and it is big that its radius of curvature becomes, and becomes and the radius of curvature of circular arc part 33,34 (with reference to single-point line, Fig. 4 (b) of Fig. 4 (a)) about equally.In other words, initial (nature) radius of curvature of each circular arc part 33,34 is set to, with the practically identical size of radius of curvature of spiral part 4a under the state that is installed on the inner ring 2.By such circular arc part 33,34 is set, these front-end faces 33 ', 34 ' and the interference of inner ring 2 have been eliminated on the two end part of helical spring 4.
The inner ring 2 that helical spring 4 has been installed as described like that is assembled on the outer ring element 1, and chimeric lid member 3.Under this state, because two front-end faces 33 ', 34 ' of helical spring 4 not necessarily are fastened on each side 12a, 18a of outer ring element teat 12 and lid member teat 18 separately, so in order to realize this engaging, outer ring element 1 and inner ring 2 is fixing, and needed instrument inserted cover in the hole 17 of member 3, rotate to the curl direction of helical spring 4.In this rotary course, the side 18a of lid member teat 18 contacts with a side's of helical spring 4 front-end face 34 ', pushes up the side 18a with tiltangle and goes up (with reference to Fig. 3 (b)).When the power that further applies greater than the tension force of helical spring 4, when making its rotation, the side 12a with tiltangle that the opposing party's front-end face 33 ' pushes up outer ring element teat 12 goes up (with reference to Fig. 3 (a).Thus, two front-end faces 33 ', 34 ' of helical spring 4 seamlessly are fastened on respectively on outer ring element teat 12 and the lid member teat 18 in a circumferential direction, simultaneously, owing to have side 18a, the 12a of inclination, have limited moving to radial direction.
Under the state that is assembled into like this, the outer diametric plane of helical spring 4 runs through its total length relatively, and the inner face of the restriction teat 31 of the restriction teat 28 of outer ring element 1 and lid member 3 becomes restriction face, and opposed mutually with certain restriction gap delta (with reference to Fig. 3 (c)).
For described restriction gap delta, consider the tolerance range when resin component element is made, be set to 0.1mm≤δ≤0.3mm, preferred δ=0.2mm.
The torque limiter of present embodiment constitutes as described like that, same with situation in the past, along with based on the hole enlargement effect of the counterrotating helical spring 4 of outer ring element 1 and inner ring 2 and produce moment of torsion, but at the generation initial stage of moment of torsion, for the deflection (with reference to the symbol 52 of Fig. 6) that produced in the spiral end in the past, the aperture surface of restriction teat 28,31 becomes restriction face, and the expansion by restriction spiral end has suppressed the generation of deflection 52.Therefore,, can seamlessly produce the hole enlargement effect of helical spring 4, produce moment of torsion without delay immediately at the generation initial stage of moment of torsion.
In addition,, do not disturb, can avoid producing local compression so can not form to the outer diametric plane of inner ring 2 because two front-end faces 33 ', 34 ' of helical spring 4 have been pre-formed circular arc part 33,34.
In addition, the mechanical relationship of side 12a (side 18a also is same) is shown in Fig. 3 (d).That is, in figure, F1 is the power on the tangent direction of front-end face 33 ', and F2 is the resistance from side 12a, and F is making a concerted effort of these.Front-end face 33 ' is subjected to inside power based on this F that makes a concerted effort.Thus, improved the rigidity of the circular arc part 33,34 of helical spring 4.
Described restriction teat 28,31 is configured to, form restriction face by the two total length that runs through helical spring 4, but, if only be provided with these restriction teats in the part corresponding with the end of helical spring 4, then produce described deflection, thereby can not prevent the generation of deflection effectively at the rear of this restriction teat.Therefore, must run through total length restriction teat 28,31 is set.In addition, also can adopt any one party of restriction in the teat 28,31 only is set, and be the structure that reaches the total length of helical spring 4 its axle direction length setting.
In addition, as preventing that moment of torsion from producing other mechanisms of deflection of the helical spring 4 at initial stage, also can replace the mechanism that forms restriction face by described restriction teat 28,31, and the aperture surface integral body of outer ring element 1 is formed the restriction face of the diameter with described restriction gap delta, also can obtain same action effect thus.
