Web17 aug. 2024 · Most common gears have teeth which are involutes, a class of curve defined by “unrolling” another shape. Our gear teeth are circular involutes, which are made by unrolling a circle. The reason we use this shape for our teeth is that it will always contact a rack with no slipping or interference. http://www.j-mst.org/On_line/admin/files/24-J2009-12618.pdf
