Problems solved by technology

[0003] Parallel shaft gear reducers are mainly composed of pinion gears, transition gears and large gears. The existing reducer gears use straight-toothed involute cylindrical gears, which inevitably have gear gaps. Limited by the installation space of the mechanism, it is difficult to design the gap adjustment mechanism. , it is very difficult to ensure the gear clearance by processing technology
The servo mechanism has a large reverse impact, high noise and poor dynamic characteristics

Abstract

The invention belongs to an electromechanical servo actuator, particularly relates to a compact type zero side clearance parallel-shaft gear speed reducer and aims at providing the gear speed reducer which can meet requirements of an electromechanical actuator for installation space, interface size, moment of force, rotating speed, side clearance and the like. The gear speed reducer comprises a shell (11), a ball screw actuator input shaft (13), a large gear retainer ring (10), a large gear (9), a transition gear (6), a transmission gear (7), a transmission shaft (7), a shell (11), a bearing (8), a small gear (2), a motor output shaft (12), a small gear baffle ring (1) and an adjusting spring (5). The gear speed reducer has the advantages that a variable tooth thickness bevel wheel is adopted so that the side clearance of the gear can be very conveniently adjusted by adjusting the size of spring force, thereby the performance of the speed reducer is increased; and the spring is arranged in a cylindrical hole of the end surface of the gear, thereby the size of the speed reducer in the axial direction is saved.

Description

technical field [0001] The invention belongs to an electromechanical servo actuator, in particular to a compact zero backlash parallel shaft gear reducer. Background technique [0002] According to the requirements of the electromechanical servo actuator, the reduction ratio of the reducer is required to be small, the output torque is large, the center distance between the input shaft and the output shaft is required to be small, and the gear backlash can be adjusted to zero. [0003] Parallel shaft gear reducers are mainly composed of pinion gears, transition gears and large gears. The existing reducer gears use straight-toothed involute cylindrical gears, which inevitably have gear gaps. Limited by the installation space of the mechanism, it is difficult to design the gap adjustment mechanism. , It is very difficult to ensure the gear clearance by processing technology. The reverse impact of the servo mechanism is large, the noise is large, and the dynamic characteristics...
