新型齿形链的啮合机制及仿真分析

The Meshing Mechanism and Simulation Analysis of a New Silent Chain

在分析研究新型齿形链与链轮的啮合机制的基础上,使用ADAMS建立了新型齿形链与链轮传动系统的数字化三维仿真模型,分析了新型齿形链内侧齿廓曲线的综合曲率半径和齿形链伸出量随链条节距、链轮齿数以及链轮齿形的变化规律.模型的仿真分析表明,对于新型齿形链与链轮传动系统,建立数字化的三维仿真模型可以有效地分析其设计参数对多边形效应的影响.试验结果表明,新型齿形链的啮合机制可以减小多边形效应的影响和减小链传动的磨损.

Based on the study of the meshing mechanism of a new silent chain and sprockets, a parametric simulation model which analyzes the meshing of a new silent chain and sprockets was built by ADAMS （automatic dynamic analysis of mechanic systems software）. The law varying of synthesized curvature radius of inside tooth outline curve and protrude value of new silent chain with the chain pitch, the teeth number of sprocket and sprocket teeth outline was analyzed. The simulation analysis shows that the meshing simulation model analysis is feasible. The test result shows that the wear of the new silent chain is decreased.
