Bevel gear-double cycloid speed reduction device for rocket launching movable platform

Abstract

The invention relates to the technical field of speed reducers, in particular to a bevel gear-double cycloid speed reduction device for a rocket launching movable platform. The device is a two-stage speed reduction device characterized by comprising a bevel gear pair and double-cycloid transmission, wherein (A) the cycloid transmission comprises a base, an output shaft, support bearings, a cycloid wheel, an eccentric bearing, an inner cycloid gear ring, a front base, an input shaft and a W output mechanism, the input shaft is supported in an inner hole of the front base through a bearing, the shaft extension end is connected with the eccentric bearing, and the input end is connected with a big bevel gear; the front base is integrated with the inner cycloid gear ring and the base in sequence; the output shaft is supported in the inner hole of the base through a bearing; and (B) two symmetrically installed small bevel gear shafts engaged with the big bevel gear are supported in wall holes of a front base box through bearings, and the small bevel gear shafts are connected with a motor; and another small bevel gear shaft is connected with a manual handle. The invention has the advantages of two-stage speed reduction, small axial size, light weight and high-degree lightweight; cycloid gear teeth are uninterrupted, so that the bearing capacity is greater than that of planet transmission with only four planet wheels; and the cost is low and is reduced to 40-55%.

Description

【Technical Field】 [0001] The invention relates to the technical field of speed reducers, and is a bevel gear-double pendulum speed reducer for a rocket launching movable platform. 【Background technique】 [0002] The deceleration device of the rocket launching platform must have high reliability, long service life, and highly lightweight. [0003] There are two types of background technology: [0004] (1) Closely round movable teeth reducer, the main problems are: the maximum allowable torque is small, the efficiency is low, η≤70%; [0005] (2) Two inventions of Zhengzhou Institute of Machinery, "Rocket Launch Activity Platform Support Arm Reducer" (20091072401.4) and "Rocket Launch Activity Platform Small Volume and Large Torque Reducer" (200910172402.9), the main problems are: [0006] Bevel gear + three-stage planetary reduction, long axial dimension, complex structure, low light weight. [Content of the invention] [0007] The object of the present invention is to provide a "bevel ge...
