Numerical simulation and experiment of non-circular gear transmission error and backlash
The difficulty in establishing the transmission error model of non-circular gears and obtaining the backlash limit its application in precision occasions.In order to improve the transmission accuracy of non-circular gears,the non-circular gear transmission error model and backlash model under bidirectional transmission are established based on the meshing line incremental method considering the eccentricity error.The influence of eccentricity and eccentricity error on bidirectional transmission error and backlash are analyzed,and the correctness of theoretical analysis is verified by transmission test.The analysis shows that the backlash of the non-circular gear can be obtained by the bidirectional transmission error.With the increase of eccentricity and eccentricity error,the two-way transmission error shows an increasing trend.Optimizing the initial phase can reduce the transmission error and backlash to a certain extent.As the load increases,the transmission error and backlash also show an increasing trend.And due to the existence of gear tooth deformation,there is a certain cumulative value of the backlash.
