ABSTRACT:
This invention pertains to gear reducers using the nutating principle. The tooth form is epicycloidal, but with the root or stem of the tooth also epicycloidal so that tooth contact between meshing teeth is essentially for one hundred eighty degress of arc of tooth contact with a uniting rather than a separating force. This tooth formation is used with a pinion beam rather than a pinion with two areas of teeth. This pinion beam has two rows of gear teeth with a relief therebetween for oil circulation. Cooling fins are provided on the housing which has a mechanism for restraining the rotational movement of the outer housing.
