Description
An item having one fixed gear and one free gear, both having the same complement of spur gear teeth, mounted on a common hub. The free gear is attached to the fixed gear by springs and operates as one gear. Upon installation with the mating gear, the teeth of the free moving gear are preset to mesh with teeth other than those of the fixed gear. This spring tension between the fixed gear and the free gear eliminates any free motion between the driver and the driven gear. The gear is used where identical and accurate transmitted motion between gears is required.
