High-torque cycloidal speed-reduction device of rocket launching moving platform

Abstract

The invention relates to the technical field of a speed reducer, in particular to a high-torque cycloidal speed-reduction device of a rocket launching moving platform. The high-torque cycloidal speed-reduction device of the rocket launching moving platform is characterized in that: a two-stage speed-reduction device is formed through cycloidal transmission of a bevel gear pair and three cycloidal wheels, wherein, (A) the cycloidal transmission is constituted by a base, an output shaft, a supporting bearing, three cycloidal wheels with 120 degrees of phase angles, an eccentric bearing, a pin gear housing, a gear pin, a front base, an input shaft and a W-shaped output mechanism, wherein the input shaft is supported in an inner hole of the front base by a bearing, the shaft extension end of the input shaft is connected with the eccentric bearing, and the input end is connected with a bevel gear wheel; the front base is sequentially integrated with the pin gear housing and the base; and the output shaft is supported in the inner hole of the base by a bearing; and (B) two systematical bevel pinion shafts which are meshed with the bevel gear wheel are supported in a box wall hole of the front base by a bearing, and one bevel pinion shaft is connected with a motor and the other bevel pinion shaft is connected with a manual handle. The high-torque cycloidal speed-reduction device of the rocket launching moving platform has the beneficial effects that: (a) two-stage reduction is adopted, the axial size is short, the weight is small and the height is lightened; (b) cycloidal gear teeth and half-buried teeth are not broken, and three cycloidal wheels are adopted, therefore, the bearing capacity of three cycloidal wheels is higher than that of epicyclic transmission of four planet wheels; and (c) the cost is reduced by 40-55 percent.
