WebSpur gear imposes only radial load on bearings. Helical gear imposes radial load and axial thrust load on bearings. What are the two advantages of using helical gears over spur gears in a transmission system? Helical Gears have teeth that are set on an angle to the gear axis. Since the teeth engage more gradually, they have a smoother and ... 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.
