The Simulation Research on Center Distance of K-H-V Involute Planetary Gear Reducer With Small Tooth Number Difference

提出了考虑K H V型渐开线少齿差行星减速器在三种不同的中心距 ;理论中心距、齿厚减薄后最大中心距和试验中心距下的工作情况 ;通过输入齿轮精度等级和齿厚偏差代号确定齿厚减薄后最大中心距 ,并试输入小于齿厚减薄后最大中心距的试验中心距确定中心距的最大偏差范围 ,为制订最经济的中心距公差提供依据 ,并开发了仿真系统软件进行验证。

In the paper working conditions of K H V Involute Planetary Gear Reducer with Small Tooth Number Difference under three different center distance;theoretical center distance、the biggest center distance after reducing width of teeth and testing center distance are considered firstly.After inputting the precision rank and symbol of deviation of width of teeth of internal gear pair,the biggest center distance after reducing width of teeth can be determined.Furthermore,by trying to input testing center distance,which is small than the biggest center distance after reducing width of teeth,the biggest deviation range of center distance after reducing width of teeth,the biggest deviation range of center distance is found.All above mentioned could offer basis to lay out the most economical tolerance of ceenter distance.Finally,the simulation software is developed.By testing the reliability and accuracy of the software are very satisfactory.
