Abstract

The invention belongs to the technical field of harmonic drive, and particularly relates to a harmonic drive gear mesh and flexible gear deformation dynamic characteristic testing system which mainly comprises a base, a harmonic wave support, a motor support, a sliding frame and two laser displacement sensor horizontally-moving systems. A servo motor and a harmonic wave sensor are fixed on the motor support and the harmonic wave support respectively, and a high-sped camera is used for recording rotation of a wave generator. Two laser displacement sensors with the horizontal position and the vertical position adjustable are arranged on the sliding frame and used for detecting deformation of a flexible gear. The harmonic drive gear mesh and flexible gear deformation dynamic characteristic testing system is simple in structure and convenient to assemble and disassemble, different sensors and servo motors are selected to test various dynamic characteristics of harmonic wave reducers of different sizes, and a fine adjustment device of a pure mechanical structure is adopted to achieve precise adjustment.

Description

Technical field [0001] The invention belongs to the technical field of harmonic drive, and specifically relates to a test system for the dynamic characteristics of harmonic drive gear tooth meshing and flexible wheel deformation. Background technique [0002] Harmonic gear transmission is a new type of transmission in modern mechanical transmission. The harmonic transmission mechanism is mainly composed of a wave generator, a rigid wheel and a flexible wheel. The rotation of the wave generator makes the flexible wheel produce controllable elastic deformation and meshes with the rigid wheel to transmit motion and power; [0003] The main factors affecting the performance of harmonic transmission include nonlinear stiffness, friction, hysteresis and kinematic errors. Scholars at home and abroad have conducted in-depth studies on the above behaviors through a large number of experimental analysis and theoretical modeling, and have achieved certain results. Current research mostly ana...
