Described input is determined torquer and is made up of outer ring, front spring, front roller, front screw; Outer ring is uniform multiple interior square groove circumferentially, interior square groove is provided with front spring, the front screw that front spring one end is arranged on the external cylindrical surface of outer ring with the mode being threaded connection contacts, the other end and front roller-contact, and front roller contacts with the arc groove on power shaft again.
Described output is determined torquer and is made up of rear spring, rear roller, rear screw; Uniform multiple interior square grooves on planet carrier inner periphery, are provided with rear spring in interior square groove, the rear screw that rear spring one end is arranged on planet carrier with the mode being threaded connection contacts, the other end and rear roller-contact, and rear roller contacts with the arc groove on output shaft again.
This device is before use, it is necessary to is first fixed in helicoidal gear frame by fluid drive transmission by the fixed gear on this device, is contained in by output sleeve on helicoidal gear power shaft. When helicoidal gear is when zero load, rotating clockwise power shaft, the inner ring of the unilateral bearing being connected with power shaft on the one hand can rotate clockwise; On the other hand, the power of power shaft is determined torquer through input and is passed to cyclic train, finally make planet carrier also can turn clockwise, the effect determining torquer through output imparts power to output shaft, and drive unilateral bearing outer ring to rotate clockwise, now the speed of unilateral bearing outer ring is more than the speed of inner ring, and unilateral bearing is in and surmounts state, now the rotating speed of the output shaft of whole device is more than the rotating speed of power shaft, and helicoidal gear output shaft can rapid increase. When helicoidal gear load, the moment of resistance being imparted on output shaft can increase, when the moment of resistance exceed input determine torquer with export determine the predetermined torque of torquer time, determine torquer for two will skid, output shaft will slow down, the speed making unilateral bearing outer ring is eventually equal to the speed of inner ring, unilateral bearing is at synchronous regime, now, acting on the moment on power shaft to be directly passed to output shaft and be ultimately applied on helicoidal gear power shaft, helicoidal gear now will slowly rise.
The beneficial effects of the utility model are: 1, when empty, and this device is a speeder so that helicoidal gear output shaft can rapid increase, improve efficiency; 2, when loaded, this device is automatically converted to a constant speed device so that helicoidal gear output shaft can slowly rise.
