Abstract

The invention discloses a rocket movable launcher supporting arm speed reducer. The speed reducer comprises an input case, an output case, an input bevel gear pair and a three-stage planetary gear train, wherein the bevel gear shaft of the input bevel gear pair extends to the outside of the input case, a bevel gear wheel is arranged on a one-stage sun gear shaft, the input bevel gear shaft and the one-stage sun gear shaft are arranged in the case and supported and positioned by bearings, the outer surface of a one-stage annular gear is used as a part of the case and separately connected with the input case and two-stage and three-stage annular gears through connecting pieces, the two-stage and three-stage annular gears have integral structures, a one-stage planet gear is arranged on a one-stage planet carrier and supported by bearings, the outer surface of the two-stage and three-stage annular gears is used as a part of the case, the two ends of the annular gears are coupled with the output case and the one-stage annular gear, a three-stage planetary gear is arranged on a three-stage planet carrier and supported by bearings, a three-stage sun gear is arranged in a floated manner, and the three-stage planet carrier is used to output the motion and powder. The invention has the advantage of high efficiency and small volume.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a speed reducer for a support arm of a rocket launching movable platform. Background technique [0002] The support arm reducer of the rocket launch platform must have high reliability, long life, high efficiency, small size, large output torque, low operating speed, large speed ratio, and high transmission rigidity. At present, the deceleration device used in the support arm of the rocket launch platform in our country is a close-to-round movable tooth reducer, which belongs to the differential transmission with few movable teeth. The maximum allowable torque of the reducer with this structure is small, the transmission efficiency is low, and η<70%, so it cannot fully meet the above-mentioned performance requirements. Contents of the invention [0003] The purpose of the present invention is to provide a support arm reducer for a rocket launching movable platform with compact structure, ...
