Abstract
A gerotor motor including a brake package, and a method for setting the load holding torque of the brake package. The endcap assembly ( ) defines a set of internal threads ( ) disposed adjacent a brake package piston member ( ). An enclosure member ( ) defines a spring seat ( ) for a set of Belleville washers ( ), and defines a set of external threads ( ) engaging the internal threads ( ). Upon assembly of the motor and brake package, a resistance load is applied to a motor output shaft ( ) corresponding to a desired load holding torque. The motor is pressurized sufficiently to rotate the output shaft in opposition to the resistance load. The enclosure member ( ) is rotated so that it moves axially in a direction to increase the bias preload on the Belleville washers ( ) until the output shaft ( ) no longer rotates.
