Equivalent Substitution Of Theoretical And Experimental Tooth Profile Of The Two Tooth Difference Cycloidal Gear Planetary Transmission

The two teeth difference cycloid gearing now is widely applied in the low transmission ratio gearing because of its anti-gluing performance . For the sake of the non-continuity of the flank profile of cycloid gear in the two teeth difference , the complexity in manufacturing technology is resulted and the precision cannot be guaranteed . The document provides theory and method of the equivalent substitution on cycloid gear transmission in two teeth difference in accordance. With the above conditions , We carried out the trial study . A kind of practical product is selected and a model machine is made . The flank profile of the equivalent substitution is calculated based on the optimization design method about the model machine according to the previous cycloid gear in two teeth difference . The cycloid gear reducer in two difference which has the equivalent substitution gear profile.The comparative trial is engaged concerning temperature rise , noise , vibration and efficiency , etc. . of reducers made from cycloid gear with two different models on open-type testing stand . The force conditions of two types of cycloid gear are compared with each other . The trial research and the force analysis on the pin-cycloid gear in two teeth difference are finished based on the equivalent substitution method . We conclude that the cycloid gear in two teeth difference designed based on the equivalent substitution method is theoretically scientific and practically feasible . A way of making cycloid gear with two teeth difference is explored for the cycloid reducer manufactures in China.
