摘　　要：以精确保证多级平行轴齿轮减速器的总传动比为设计目标,研究了在给定中心距、总传动比条件下,齿轮各参数之间的数学关系;建立了多级减速器齿轮齿数选择的数学模型;开发了多级齿轮减速器的齿数计算程序,使设计者可以快速确定多级平行轴齿轮减速器各级齿轮的齿数组合,在合理的模数、螺旋角、变位系数取值范围内,保证各级中心距,并精确保证总传动比。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.
