Combination correction method of cycloid gear tooth shape and its optimization design

cycloidal wheels;  Composite shape method;  Tooth shape correction

For the cycloidal wheel whose tooth shape has been determined, the correction method and correction amount of cycloidal wheel are optimized and analyzed by the improved composite shape method when the correction method and correction amount are unknown. At the same time, the simple "equidistance + distance" correction method of the process is used to replace the more complex angle correction method of the process, and the method is used to calculate the amount of equidistance and distance correction quickly, and the work efficiency is significantly improved compared with the traditional calculation method. The calculation results show that among the various correction methods of cycloid gear tooth shape, the correction method of "positive equidistance + negative shift distance" is the ideal correction method for the tooth shape of cycloidal wheel. This correction method has an ideal tooth shape, simple processing technology, and has certain promotion and use value in design and manufacturing.
