Description
Technical field
The present invention relates to a kind of clutch, particularly relate to a kind of for the bidirectional clutch in electric operating mechanism of circuit-breaker。
Background technology
In electrical power distribution apparatus killer switch; often need to use a kind of motor-operating mechanism with bidirectional clutch; this kind of operating mechanism purposes is to generally use motor to drive reducing gear output moment of torsion or power when control circuit not power-off, controls the operation of chopper on/off switch；Use manual operation when control circuit power-off, directly pull breaker main shaft on/off switch。Owing to reducing gear transmission is relatively larger, so must be disengaged with reducing gear by moment output mechanism when manual, bidirectional clutch has been exactly the effect disengaging reducing gear when manual。
Traditional bidirectional clutch structure is as shown in Figure 1 to Figure 2, it includes star-wheel 10 and the sprocket wheel 11 being arranged at outside star-wheel 10 rotatably, described star-wheel 10 is provided with two grooves 13 for housing roller 12, in described groove 13, processing tiltedly carves 14, the described both sides tiltedly carving 14 are respectively provided with roller 12, and in described groove 13, offering the spring eye for assembling spring 15, spring 15 is installed in hole by sleeve 16, and the driving lever 18 of shift fork 17 is arranged between interior two rollers 12 of each groove 13。During electric operating, motor via reducer structure band movable sprocket 11 rotates, and sprocket wheel 11 tiltedly carves 14 by what roller 12 compressed star-wheel 10, and the tooth-shape structure thereby through star-wheel 10 endoporus drives breaker main shaft on/off switch。Time manual, shift fork 17 stirs roller 12 clamp sleeve 16 so that spring 15 compresses in star-wheel spring eye by driving lever 18, and roller 12 directly drives star-wheel 10 to rotate, thus driving breaker main shaft on/off switch, now sprocket wheel 11 and reducing gear are failure to actuate。The shortcoming of this kind of structure is:
1 once sleeve 16 is jagged with star-wheel spring eye or spring 15 is tired or weares and teares flexible can the blocking of excessive rear sleeve 16 and roller 12 can not be made to carve and tight tiltedly carve on 14 in star-wheel 10, thus electronic time sprocket wheel 11 can dally, thus can not drive star-wheel 10 and breaker main shaft motion。Reliability is poor。
2, owing to the spring eye on star-wheel 10 is both needed to processing, and hole wall must be more smooth, also must be substantially vertical with the angle of roller 12, and the degree of depth is consistent, quantity is more again, (particular number is determined to have two pairs by the moment of torsion that transmits or multipair roller transmits moment of torsion jointly) processing is more difficult, adds production cost。
Summary of the invention
It is an object of the invention to provide a kind of bidirectional clutch, it has the advantages that processing is simple, easy for installation, security reliability is good and production cost is low, effectively solves bidirectional clutch Problems existing in prior art。
It is an object of the invention to be achieved through the following technical solutions:
A kind of bidirectional clutch, it includes star-wheel and is coaxially assemblied in the sprocket wheel outside star-wheel rotatably, described star-wheel offers at least one groove for housing roller, in described groove, processing is tiltedly carved, the described both sides tiltedly carved are respectively provided with roller, wherein, between sidewall and the roller of this sidewall close of described groove, elastomeric element is set, the driving lever of shift fork is arranged between two rollers in groove, and at least one pulling needle also installed by described shift fork, corresponding pulling needle processes hole clipping on the wheel face of star-wheel, and described pulling needle is inserted in hole clipping。
Especially, described elastomeric element is helical spring。
Especially, the edge of described star-wheel offers two grooves with central point for point of symmetry correspondence。
Especially, the number that arranges of described pulling needle is two, corresponding to processing two hole clippings on the wheel face of star-wheel。
Especially, described hole clipping is any one of through hole or blind hole。
During electric operating, motor is rotated by reducing gear band movable sprocket, and sprocket wheel compresses the face of tiltedly carving of star-wheel by roller, reaches on/off switch purpose by the dynamic chopper motion of main shaft of the internal tooth pore area of star-wheel。During manual operation, spanner stirs roller by shift fork and the driving lever that is contained on shift fork, makes roller unclamp face of tiltedly carving, now sprocket wheel is failure to actuate, star-wheel is stirred, thereby through the dynamic breaker main shaft of internal tooth pore area of star-wheel, thus reaching on/off switch purpose again through the pulling needle being loaded on shift fork。
Beneficial effects of the present invention is, described bidirectional clutch compared with prior art avoids opens spring eye on the sidewall of groove, processing is simple, reducing production cost, eliminate sleeve simultaneously, spring is directly and the sidewall of groove and roller contact, shift fork installs additional pulling needle, stirs star-wheel by pulling needle, easy for installation, security reliability is high。

Detailed description of the invention
Technical scheme is further illustrated below in conjunction with accompanying drawing and by detailed description of the invention。
Refer to shown in Fig. 3 to Fig. 5, in the present embodiment, a kind of bidirectional clutch includes star-wheel 20 and is coaxially assemblied in the sprocket wheel 21 outside star-wheel 20 rotatably, the edge of described star-wheel 20 offers two grooves 23 for housing roller 22 with central point for point of symmetry correspondence, in described groove 23, processing tiltedly carves 24, the described both sides tiltedly carving 24 are respectively provided with roller 22, between sidewall and the roller 22 of this sidewall close of described groove 23, helical spring 25 is set, the driving lever 27 of shift fork 26 is arranged between two rollers 22 in groove 23, and two pulling needles 28 also installed by described shift fork 26, corresponding pulling needle 28 processes two hole clippings 29 on the wheel face of star-wheel 20, described pulling needle 28 is inserted in hole clipping 29。
The work process of above-mentioned bidirectional clutch is: during electric operating, and motor is rotated by reducing gear band movable sprocket 21, and sprocket wheel 21 compresses the face of tiltedly carving of star-wheel 20 by roller 22, reaches on/off switch purpose by the dynamic chopper motion of main shaft of the internal tooth pore area of star-wheel 20。During manual operation, spanner stirs roller 22 by shift fork 26 and the driving lever 27 that is contained on shift fork 26, roller 22 is made to unclamp face of tiltedly carving, now sprocket wheel 21 is failure to actuate, star-wheel 20 is stirred again through the pulling needle 28 being loaded on shift fork 26, thereby through the dynamic breaker main shaft of internal tooth pore area of star-wheel 20, thus reaching on/off switch purpose。
Above-mentioned bidirectional clutch is not only processed simply, reduces production cost, and easy for installation, security reliability is high。
Above example simply elaborates ultimate principle and the characteristic of the present invention; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention; the present invention also has various change and change; such as pulling needle and hole clipping the change that number carries out because needing the difference of moment of torsion of transmission is set, these changes and changing both fall within the claimed scope of the invention。Claimed scope is defined by appending claims and equivalent thereof。
