Most of overrunning clutch reducing gears of domestic production at present have the following disadvantages in the process of slowing down: the one, and waste of material and difficulty of processing are big, processing cost is high because roughness, the accuracy of gear, pitch circle to negative camber circular runout and quality of fit requirement height, cause; The 2nd, because complex structure, parts are many, manufacturing procedure is numerous and diverse and work efficiency is low; The 3rd, in use mechanical transmission is not steadily, circular runout is big, and noise is big, easily causes flexible dumbly, and transmitting torque is little, is prone to skidding.
Summary of the invention
The purpose of this utility model is at existing existing the problems referred to above, and a kind of noise is little, simple and compact for structure in the process of slowing down, operational safety is high is used for reducing gear on the overrunning clutch and provide.
The purpose of this utility model can realize by following technical proposal: a kind of reducing gear that is used on the overrunning clutch, this reducing gear is arranged between motor and the clutch mechanism, comprise first coupling shaft that is connected on the clutch mechanism and second coupling shaft that links to each other with motor, it is characterized in that, one end of described first coupling shaft is connected with rotating disk, rotating disk is provided with several bearing pins, outer race at above-mentioned rotating disk is connected to ring gear, on second coupling shaft, be socketed with central gear and be installed on the middle part of rotating disk by second coupling shaft, be provided with several planetary pinions between ring gear and central gear, above-mentioned planetary pinion is installed on the rotating disk by bearing pin and is meshed with ring gear and central gear respectively.
Can realize engine start and deceleration by this reducing gear, can drive first coupling shaft when wherein clutch mechanism is worked and rotate and then drive dial rotation together, can rotate with second coupling shaft during machine operation.When actuating motor, drive the rotation of second coupling shaft, and then the central gear that links to each other with second coupling shaft also rotates, planetary pinion is because of the rotation rotation of central gear, and produce revolution with the ring gear engagement that limits rotation, rotation is passed to first coupling shaft, and first coupling shaft drives clutch mechanism and advances engine start.
When needs slow down, clutch mechanism reaches planetary pinion by the motion that first coupling shaft transmits through central gear, because rotating disk does not rotate, can only rotation so planetary pinion can not revolve round the sun, drive the rotation of the ring gear and second coupling shaft simultaneously and be sent to motor again, prevent launched machine hypervelocity and damage motor, reach the purpose of deceleration of motion output.
At the above-mentioned reducing gear that is used on the overrunning clutch, described bearing pin is three; Described planetary pinion is three.Wherein planetary pinion is placed on the bearing pin, is convenient to location and rotation.
At the above-mentioned reducing gear that is used on the overrunning clutch, described rotating disk is cylindric.
At the above-mentioned reducing gear that is used on the overrunning clutch, the cylinder interior edge face of described rotating disk is provided with an attachment hole, and the second above-mentioned coupling shaft is installed in the attachment hole of rotating disk.When such second coupling shaft is installed the attachment hole of rotating disk, thereby central gear is fixed.
Compared with prior art, originally the advantage that is used for the reducing gear on the overrunning clutch be since adopted planetray reducer be run slowly stable, transmitting torque big, the working procedure noise is little, the reducing gear production and processing on this clutch is convenient, simple and compact for structure, safe and reliable in addition.
