Definition Errors in Sprocket Ring on Passages at Gear Shaving

摘要

Sprockets with small number of teeth are widely applied in oil pumps, planetary transfers, and hydro engines. The Gear-Shaving process of such sprockets undergoes a difficulty in the manufacture, especially when accuracy of a process with more than 8-th degree is required, and when classical methods are applied. However, at processing of Sprockets Gear-Shaving, the factor of overlapping in tool grapping changes within the limits of 1.1 ...1.2. Therefore, the properties of the involutes of gearing shown clearly. Much works are devoted to study of sprockets with small number of teeth processed by Gear-Shaving operation, but no attempt has been carried out to define errors on each passage. Experimental results indicate that the change of crossbreeding angle of axes on each passage allows reducing number of draft passages. However, it shown that the errors of general length depend segnifically on previous process errors. The effect of preparation errors also taken under consideration in present study. Thus, reducing errors of gear ring of Sprockets may be consider as an important task for improving the loading ability of issue and technical level of the product.
