Analysis of modifying gear error based on grinding gear method

To solve the gengeated error in normal gear processing,the precision grinding of gears processing and advanced detective technology were applied to increase the level of gear,the corresponding relationship between the error factors and gear precision index was established by analyzing the error factors in gear processing production.Combined with the precision grinding gears characteristics and advantages,the method that gear precision be improved by the precision grinding of gears was proposed.On the premise of the gear error,the causes of error,gear grinding principle,modifying method were suggested to get perfect improved method,thus the impact of transmission mechanism precision by the error was avoided.The results suggest that,using precision gear grinding ways to modify the error,it is the shortcut in effective improving the accuracy of the gear,on the basis of the conventional methods,it can improve the level of 2 to 3 grades.
