Problems solved by technology

[0004] The precision of the RV reducer is high, which requires high precision of the test device. The traditional test device can only meet the requirements of measuring a single performance of the RV reducer. Several devices are required to measure multiple performance parameters. , which requires multiple disassembly and assembly of the reducer, and multiple disassembly and assembly will bring a large workload and installation errors

Abstract

The invention relates to a testing device for testing dynamic performance of various models of RV speed reducers, and belongs to the technical field of precision testing. The testing device is mainly characterized in that two high-accuracy angle encoders and two high-accuracy torque and revolution speed sensors are arranged at the two ends of an RV speed reducer to measure an input revolution speed, an input torque and an input angle as well as a revolution speed, a torque and an angle after speed reduction of the speed reducer; inputting is performed through a servo motor, and tail-end loading is performed through a magnetic powder brake to measure the performance of the speed reducer in various loading states; data acquisition and controlled operation are performed through an industrial tablet computer. The testing device is reasonable in structure, can be used for measuring performance such as transmission errors, transmission efficiencies, return differences and starting torques of various models of RV speed reducers in the loading states, and has relatively high accuracy. Thus, the testing device can be widely applied to the technical field of precision testing.

Description

technical field [0001] The invention relates to the technical field of precision testing, in particular to a testing device for testing the dynamic performance of various types of RV reducers. Background technique [0002] RV reducer is a new type of two-stage closed planetary reducer with small tooth difference. It is developed from the traditional cycloidal pin wheel planetary transmission. In recent years, it is mostly used in high-precision robot transmission. The transmission has a series of advantages such as large transmission ratio range, small size, light weight, high motion precision, small hysteresis, high transmission efficiency, stable transmission, and strong bearing capacity, so it has received widespread attention and developed rapidly. [0003] The RV reducer originated in Japan. At present, many domestic manufacturers have successfully developed serialized RV reducer products. Although my country has intensified research on the design theory and methods of ...
