Performance of eccentric-cycloid engagement with change in the interaxial distance: Modification of tooth configuration

The influence of the interaxial distance of the gears on the performance of an eccentric-cycloid engagement is studied by computer simulation. With wide variation in the interaxial distance, there is little shift in the contact point of the profiles, which remains at the front of the cycloid curves describing the tooth shape. This greatly simplifies gear manufacture for such engagements, since the surface area to be finished is considerably reduced.
