Tooth Number Design of Multi-stage Parallel Shaft Gear Reducer based on Accurate Transmission Ratio

With the design objective of accurately ensuring the total transmission ratio of the multi-stage parallel shaft gear reducer,the mathematical relations among the gear parameters are studied under the condi?tions of given center distance and total transmission ratio.The mathematical model of gear tooth number selec?tion of multi-stage reducer is established.The program for calculating the number of teeth of the multi-stage gear reducer is developed,which enables the designer to quickly determine the number of teeth of each gear of the multi-stage parallel shaft gear reducer,and ensure the center distance of each stage and the total transmis?sion ratio accurately within the reasonable value range of modulus,helix angle and modification coefficient.
