Abstract

The present invention discloses an RV speed reducer transmission return difference testing device which is formed by a base, a loading device, a measuring device and a locking device. The loading device is formed by a servo motor, a motor bracket and a motor-side coupler. The measuring device is formed by a torque rotation speed sensor, an input end coupler, an encoder, an input end flange, a coupler support seat, and a sensor support seat. The locking device is formed by a locking pin, an output end locking flange and a speed reducer support seat. Compared the a previous RV speed reducer transmission return difference testing method, the device has the advantages that the testing of static and dynamic return differences can be carried out, the efficiency is higher than that of the traditional return difference testing method, a program-controlled loading mode is employed, and the degree of automation is high. The device has the advantages of a simple structure, high testing precision, a low testing environment requirement, and a high degree of automation, and the high precision performance testing and detection requirements of an RV speed reducer by an industrial robot can be satisfied.

Description

technical field [0001] The invention relates to the technical field of precision gear transmission performance measurement, in particular to a transmission hysteresis test device for an RV reducer used in joints of industrial robots. Background technique [0002] With the arrival of my country's aging population, labor costs continue to increase. Industrial robots are more and more widely used in industrial production, especially in the automotive industry. At present, common industrial robots include welding robots, palletizing robots, assembly robots, etc. The common feature of all types of robots is that they require high repeat positioning accuracy. As a joint component of an industrial robot, the performance of the RV reducer directly determines the motion accuracy of the industrial robot. Especially the transmission hysteresis of the RV reducer has an important influence on the positioning accuracy of the reciprocating industrial mechanical arm. [0003] The transmi...
