Accuracy Measuring For the RV Reducer Cycloid Gear and Manufacturing Error Analysis

摘要

RV reducer is an important function part of industrial robot joints. The cycloid gear measuring problem is the key part of high precision RV reducer manufacturing. A brief introduction to the forming principle and formulas of RV reducer cycloid tooth contour. A new method for measuring the contour accuracy of RV reducer cycloid gear is proposed in the paper, which is used coordinate measuring machine to detect the tooth contour error of cycloid gear. The measuring method, steps and precautions in measuring are discussed in detail. Proposing a data processing and verification program and the cycloid gear manufacturing error is also analyzed. The detection method is certified to meet the application requirements through actual measurement.
