WebOne thing that was mentioned in few places was that involute geometry makes weaker gears with low tooth count. Playing with some web tools ( cycloid, involute ), the results … WebThe involute of the cycloid has exactly the same shape as the cycloid it originates from. This can be visualized as the path traced by the tip of a wire initially lying on a half arch of the cycloid: as it unrolls while remaining tangent to the original cycloid, it describes a new cycloid (see also cycloidal pendulum and arc length ). The cycloidal gear profile is a form of toothed gear used in mechanical clocks and watches, rather than the involute gear form used for most other gears. This is for three reasons. 1. To reduce friction, watch and clock movements require teeth and pinion leaves to be polished. Cycloidal gears can be designed so that the pinions have flat surfaces. This makes them easier to polish without adversely changing their profile. hbr electron geometry
