Problems solved by technology

[0005] The existing RV reducer rotary transmission accuracy error measurement test bench only considers the influence of the cycloid gear tooth profile error, and does not take into account the errors of other components other than the cycloid gear, and the calculation is complicated
Therefore, when there are RV reducers with multiple crankshafts, double cycloid wheels, and complex input and output mechanisms, as well as processing and assembly errors and clearances of high-speed stages and other components, the rotary transmission can be obtained according to existing methods. The error is more complicated

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to help understand the content of the present invention.

[0034] like Figure 4 As shown, the present invention provides an RV reducer slewing transmission accuracy error measuring platform, including a dividing head 8, a measuring block 4, an RV reducer 2 and a measuring instrument for determining the position coordinates of a measuring point on the measuring block 4; The instrument is a coordinate measuring instrument 5 . During measurement, the three-coordinate measuring instrument 5 determines the position of the coordinate axis of the reducer and the coordinate origin, and establishes a space rectangular coordinate system with a fixed point on the frame as the coordinate origin, wherein the axis of the reducer is one of the coordinate axes and locked to make the three The coordinate measuring machine 5 is fixed in the direction of th...

Abstract

The invention discloses a test bed and method for measuring the rotation transmission precision error of an RV reducer. The method includes the steps of a, measuring the slope k0 of the connecting line between two selected detecting points on a measuring block fixed on the output shaft of the RV reducer; b, allowing the input shaft of the RV reducer to rotate a certain angle phiin, n, and measuring the slope kn of the connecting line between the two detecting points on the measuring block again, wherein the plane changing times of the measuring block during the rotation is m; c, calculating the rotation transmission error epsilon according to the kn, k0, m and phiin, n. The method has the advantages that the measuring of existing methods is simplified, the problems that many parameters exist in the measuring process and calculation is complicated are solved, the method is simple in calculation and few in measuring parameters, and the rotation transmission precision error can be obtained simply.

Description

technical field [0001] The invention relates to a measurement technology for the rotation accuracy error of an RV reducer, in particular to a test bench for measuring the rotation accuracy error of an RV reducer and a measurement method. Background technique [0002] The rotary transmission accuracy is one of the main performance indicators of the RV reducer. It refers to the difference between the actual output rotation angle and the theoretical output rotation angle when the input shaft rotates through any angle. The performance of the RV reducer directly affects the positioning accuracy of industrial robots, so how to improve the rotary transmission accuracy of the reducer is of great significance to the theoretical research and practical application of the reducer. [0003] The popularization of industrial robots is an effective means to realize automated production, improve social production efficiency, and promote the development of enterprise and social productivity. ...
