The equations of motions between two teeth are … WebMar 4, 2024 · The most important contributing factor of dynamic behavior is the stiffness of the teeth, which changes constantly throughout the operation. The calculation of gear stiffness is important for determining the load dis- tribution between the gear teeth when two sets of teeth are in contact.

WebBending Stresses. The calculation of bending stress in gear teeth can be based on the Lewis formula. where W t = transmitted load (N), F = face width (m or mm), m = module (m or mm), and Y = the Lewis form factor and can be found from the below table. When teeth mesh, the load is delivered to the teeth with some degree of impact. WebMar 1, 1996 · To establish this fact, a dynamic analysis of the gear drive with involute tooth and modified tooth profiles (using C.S.) is performed. For this, first the tooth deformation is found and then the tooth dynamic load is determined for all reasonable speeds.
