Abstract
A crank assembly for displacing a load includes a motor and a displacement arm assembly. The motor includes a rotatable output shaft that defines a rotation axis. The displacement arm assembly includes a swingable crank arm and a support roller bearing. The swingable crank arm is coupled to the output shaft to swing about the rotation axis when the output shaft rotates. The swingable crank arm defines a pivot end adjacent the rotation axis and an opposite displacement end. The support roller bearing is rotatably supported on the swingable crank arm proximate the displacement end. The support roller bearing is configured to engage the load. The support roller bearing defines a bearing axis, which is substantially parallel to and offset from the rotation axis.
