Filter speed reducer

Abstract

The invention discloses a filter speed reducer, which comprises an eccentric shaft, a split spine half-axle dual gear, a fixed gear, an output gear and a rubber alloy layer. The split spine half-axle dual gear, the fixed gear and the output gear are helical bevel gears which are organically meshed to form a backlash-free precise transmission pair and can adaptively compensate for abrasion of tooth surfaces; the rubber alloy layer adhered on the split spine half-axle dual gear can ensure that a transmission component filters fluctuation caused by the conversion of a low speed and high torque into a high speed and low torque of a motor, processing and mounting errors and the like through a controllable elastic distortion quantity in a designed transmission accuracy and bearing capacity range, effectively prevents generation of nonlinear coupled vibration of a transmission system caused by influences of extreme working conditions and special environments, and solves the problems of generation of jam even inflexible lock and the like of the transmission component. Thus, the filter speed reducer has the advantages of high precision, high reliability, long service life, high torque, low energy consumption, small volume and the like, and can be widely applied to equipments in engineering fields, such as robots, space flights, ships and vehicles.

AI Technical Summary

Problems solved by technology

[0003] In the prior art, although precision transmission parts and systems such as harmonic reducers and RV reducers are widely used in electromechanical transmission systems for important equipment in robotics, automation, aviation, aerospace and other engineering fields, since the motor is used as the power source of the transmission system , the mechanical energy produced is in the state of high-speed and small torque, and when output through the reducer, it becomes a state of low-speed and high-torque, which inevitably leads to fluctuations in the torque of the transmission system, the assembly and manufacturing errors of each component itself, and the synchronism of the shaft system. Axiality and transmission meshing errors, wear of components in the transmission mechanism, especially under the influence of extreme working conditions and special environments, the large fluctuations generated will make the operating state of the transmission mechanism worse, and inevitably increase the operation of the transmission mechanism. Vibration and noise, resulting in "stuck" or even "stuck" phenomenon

For example, the single-stage transmission ratio range of harmonic transmission is limited (usually <360), and there are disadvantages such as low torsional stiffness, small torque, and poor reliability of elastic elements, and it is easy to generate nonlinear coupling vibration with solar panels and other executive systems and cause stalling Serious problems such as "jamming" or even "jamming" occur, making the execution systems such as the solar panel deployment mechanism unable to work normally, causing the satellite to lose control or even be completely scrapped
