Problems solved by technology

[0008] There are two comprehensive error vectors with similar frequencies in the motion error of the harmonic reducer transmission, and the simple harmonic waveform changes. If the processing and assembly are improper, the amplitude of the two comprehensive error vectors with similar frequencies will be similar, and beats will occur. This beat frequency phenomenon will seriously affect the dynamic characteristics of the system
[0009] Furthermore, in the harmonic reducer, the flexible spline and the output shaft are generally rigidly connected, and the beat frequency phenomenon mainly generated by the comprehensive eccentric vector of the flexspline part as the error source will be amplified and transmitted, which will seriously affect System Dynamics

Abstract

The invention relates to a flexible gear output device used in a harmonic speed reducer, which includes a wave generator, and is characterized in that an input shaft is installed in the wave generator; a steel wheel is sleeved at the periphery of the wave generator; a flexible gear is sleeved at the front end of the steel wheel; an output shaft is arranged at the working end of the flexible gear; meanwhile, a buffering bedding assembly is arranged inside the working end of the flexible gear. Therefore, flexible gaskets are used for vibration absorption, the phenomenon of beat frequency is greatly weakened, and the flexible gear output device has a simple structure and is convenient for assembly and implementation.

Description

technical field [0001] The invention relates to a flexspline output device, in particular to a flexspline output device for a harmonic reducer. Background technique [0002] When the existing harmonic reducer is working, the dynamic measurement of its transmission motion error presents a "beat frequency" phenomenon in which the amplitude of the motion error varies from large to small, which requires dynamic performance of industrial robots, electronic manufacturing equipment, etc. Very disadvantageous for higher control systems. [0003] The beating frequency phenomenon is mainly determined by the comprehensive influence of the processing error and assembly error of each component that constitutes the harmonic reduction gear and the frequency characteristics of the harmonic drive. Harmonic transmission will form multiple simple harmonics. When the amplitudes of two simple harmonics are similar and the frequency difference is small, the superimposed composite waveform is the...
