Meshing Efficiency Calculation of Inner Parallel Indexing Cam Mechanism
摘要
Abstract
In order to establish an efficiency model of inner parallel indexing cam mechanism,the relative sliding velocity between the cam and needle gears was analyzed. Meshing force between the cam and needle gears was calculated by consid-ering the influence of friction. Based on the velocity and the force,the meshing efficiency between the cam and needle gears was derived. The relationship between average meshing efficiency and key parameters were discussed. The average meshing efficiency formula was derived on the basis of the fitting theory with eccentricity and the needle gear distribution circle ra-dius as the independent variables. It is concluded that the average efficiency decreases with the increase of the needle gear distribution circle radius and increases with the increase of the eccentricity.关键词
