Experiment table for detecting dynamic characteristics of harmonic reducers

Abstract

The invention discloses an experiment table for detecting dynamic characteristics of harmonic reducers, which comprises an X guide rail arranged on a bottom plate, as well as a first servo motor, wherein the first servo motor is fixed on the X guide rail and is axially connected with a follow-up harmonic reducer; the follow-up harmonic reducer is fixed on the X guide rail and is axially connected with a first torque sensor through a first torsion bar; the first torsion bar sensor is axially connected with a first angle measuring device; the first angle measuring device is connected with a first connecting shaft; and a detected harmonic reducer is arranged on the X guide rail through a mounting bracket and a positioning piece. The experiment table is characterized in that a Y guide rail perpendicular to the X guide rail is arranged on the bottom plate; when the detected harmonic reducer is a right-angled reducer, a second angle measuring device is arranged on the Y guide rail and is axially connected with a second torque sensor; and the second torque sensor is axially connected with a second servo motor. The experiment table has the advantages of good universality and capability of completing the task of testing the dynamic characteristics of a plurality of detected harmonic reducers on one experimental device.

Description

technical field [0001] The invention relates to a performance test bench for a harmonic reducer, in particular to a performance test bench for a general (including right-angle type) harmonic reducer. Background technique [0002] With the continuous development of high-precision motion control technology, high-reliability harmonic reducers are increasingly required in fields such as missiles, satellite pose control, robot joint transmission, and machine tool rotation. High-reliability harmonic reducers need corresponding testing methods to inspect their quality. Traditional harmonic reducer performance testing devices generally can only detect one or two dynamic characteristics of the reducer, which has poor versatility. Using traditional methods to detect all the dynamic characteristics of the reducer requires multiple tooling, which is time-consuming and laborious, and it is difficult to ensure the installation accuracy. In addition, most of the traditional detection dev...

The traditional harmonic reducer performance detection device generally can only detect one or two dynamic characteristics of the reducer, which has poor versatility

Using traditional methods to detect all the dynamic characteristics of the reducer requires multiple tooling, which is time-consuming and laborious, and it is difficult to ensure the installation accuracy

In addition, most traditional detection devices require operators to perform a large number of operations during the inspection process, and the degree of automation is low.

Because of the above problems, the traditional detection equipment is limited in practical use
