Research on Analysis of Force and Contact Strength for Translation Movable Teeth Drives

The force analysis of translating movable teeth under the conditions of oneface contact and twoface contact between the movable tooth and a guide slot is discussed in this paper. According to the characteristics of translating movable teeth drives, the deformationcoordination equation is established, and then forces acting on the movable teeth for above mentioned two cases can be determined. Based on it, the formulae of contact strength of mesh points between the movable teeth and the surge wheel, the movable teeth and the internal gear are derived. A numerical example is given. 
