Friction Involute gears normally mesh with 2 or 3 teeth in contact at the same time while cycloidal gears can be designed so that only 1 or 2 teeth are in contact at a time Because some sliding contact occurs in all gear designs involute gearing will tend to have more friction that a comparable cycloidal designGet Price List
