Abstract

The invention discloses a hollow type gear transmission speed reducer. The hollow type gear transmission speed reducer comprises an output disc, a pin gear housing, a support flange, planet wheels, a crankshaft, a cycloidal gear, a motor and rotary shafts. The output disc and the support flange are installed at openings in the two ends of the pin gear housing correspondingly. The middle of the output disc is provided with a left through hole. The middle of the support flange is provided with a right through hole. The left through hole, an inner cavity of the pin gear housing and the right through hole communicate sequentially to form a first through hole. A first gear is arranged at one end of an input shaft of the motor. Each rotary shaft is provided with a second gear and a third gear. All the second gears mesh with the first gear, and each third gear meshes with the corresponding planet wheel. The hollow type gear transmission speed reducer has the characteristics of being good in transmission performance, small in machining difficulty and low in production cost and is provided with the through holes capable of holding wirings and tubings, abrasion of the wirings and the tubings can be avoided effectively under the circumstance that the transmission performance is not influenced, and thus the whole speed reducer looks neat and attractive.

Description

technical field [0001] The invention relates to a speed reduction device, in particular to a hollow gear transmission speed reduction device. Background technique [0002] The transmission of the cycloidal pinwheel is well known. Compared with ordinary gear transmissions, the cycloidal pinwheel has three major characteristics (big transmission ratio, large load-bearing capacity, and high rigidity), two high (high transmission efficiency, high motion precision), A small (small hysteresis) feature. The formation of the first reduction unit of the reduction transmission device: the rotation of the motor drives the first gear to rotate, and the first gear is externally meshed with the second gear on the rotating shaft to form a first-stage reduction; the formation of the second reduction unit: The second gear on the rotating shaft drives the rotating shaft to rotate, and the third gear on the rotating shaft is externally meshed with the planetary gear to form a second-stage dec...
