WebThe involute profile is made by taking a string and wrapping it around a cylinder. We then trace the curve of the end of the string as it unwinds. As you can see, a curve with a constantly increasing radius is made. This is very similar to the Fibonacci Curve sometimes known as the Golden Spiral. 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.
