Abstract
A retainer mechanism for an axial piston machine embodies a shoe plate having a plurality of openings defined in a circumferential outer portion thereof to receive a plurality of shoes and a biasing mechanism operative during assembly to apply a force to an inner portion of the shoe plate to hold the plurality of shoes against a swashplate disposed in the axial piston machine. Prior to assembly the shoe plate has a force transferring surface that is generally frusto-conical in shape. During assembly, the biasing mechanism applies a force to the inner portion of the shoe plate to generally flatten the frusto-conical shaped force transferring surface and urge it against a flat bearing surface of the respective shoes.
