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. WebCalculating the forces on an involute spur gear is easy. Because of the involute tooth design, the worst loading cast is when the gears mesh where the pitch diameters intersect at the tangent point. Since the gears mesh at the pressure angle (14.5°, 20° or 25°). we will have two components to deal with. The tangential force and the radial force. how fast can ishowspeed run
