Structure for input fixing of RV reducer comprehensive performance test equipment

Abstract

The invention discloses a structure for input fixing of RV reducer comprehensive performance test equipment. The structure comprises a tested RV reducer, a reducer mounting bracket, a positioning disk, a connection positioning sleeve, an input fixer, a reducer input shaft, an input flange and an input main shaft, wherein the positioning disk is mounted on the reducer mounting bracket through a group of screws; the connection positioning sleeve is mounted on the positioning disk from the input end side; the connection positioning sleeve has an inner ring and an outer ring and is provided with two groups of mounting holes; the tested RV reducer is mounted on the connection positioning disk through the group of mounting holes on the inner ring; and the input fixer is mounted on the connectionpositioning sleeve through the group of mounting holes on the outer ring. According to the structure, the input end of the tested reducer is fixed, the fixing manner is simple and rapid, and the favorable fixing effect is capable of enabling the return difference static measurement result to be more reliable.

Description

technical field [0001] The invention relates to a novel RV reducer comprehensive performance test equipment with a fixed input structure, which belongs to the fields of precision test and measurement technology, precision instruments and mechanical transmission. Background technique [0002] As one of the most basic mechanical transmission components, precision reducers are widely used in the field of high-precision transmission represented by industrial robots. RV reducer has a series of characteristics such as compact structure, light weight, large transmission ratio, stable transmission, low vibration, low noise, high efficiency, long life, etc., and has self-locking function under certain conditions. the key of. [0003] Domestic research on RV is still in its infancy. In order to guide and improve the design of RV reducer and improve the transmission accuracy, it is particularly critical to design a comprehensive performance test equipment for RV reducer to measure its...

Problems solved by technology

[0005] (1) The locking side is not uniform. Most of the existing RV reducer test benches do not adopt the measurement method of locking the input end and loading the output end according to the national standards, resulting in poor reference of the measurement results.

[0006] (2) The locking effect is poor, and the input end of the tested reducer cannot be completely fixed. The compensation method is used to compensate the error caused by the rotation angle of the input end, resulting in inaccurate measurement results.
