Abstract

The invention provides a device and a method for testing the service life of a precision cycloidal speed reducer of a robot. The reducer is subjected to service life prediction and testing by an accelerated degradation test. According to the device and the method for testing the service life of the precision cycloidal speed reducer of the robot, test cycle is greatly shortened by the accelerated degradation test, overall-process state change of the precision cycloidal speed reducer during operating can be reflected by means of continuous monitoring for reducer performance degradation by a sensor, a dynamic loading mode more accords with the actual load state of the reducer of the robot, and accordingly, accurate evaluation for the service life of the precision cycloidal speed reducer can be realized at lower cost.

Description

technical field [0001] The invention relates to the technical field of life test of a precision reducer for a robot, in particular to a life test device and method for a precision cycloid reducer for a robot. Background technique [0002] As we all know, the reducer is the most important basic component of industrial robots, and each joint needs to use different reducer products. As one of the three most important components of a robot, the cost of the reducer even accounts for more than 30% of the entire robot, while at present, more than 80% of the precision reducer for domestic robots depends on imports. The current high-precision robot reducers are mainly Japanese harmonic and RV, and their common characteristics are small size, large transmission ratio, high precision, and high torque. At present, many domestic manufacturing companies have begun to innovate and create the structure, manufacturing, and processing technology of robot precision reducers, and have also pro...
