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. WebThis is called the gear ratio. If a driven gear with 24 teeth is meshed with a drive gear with 48 teeth, there is a 1:2 gear ratio. That means the driven gear will turn twice as fast as the drive gear. Gears are found in many machines where there is the need to control the speed of rotary movement and turning force. road accident fund affidavit
