<p>An internal caliper brake includes a rotor including an annular support for securement to a shaft to be braked, the annular support mounting an annular U-shaped housing having an annular U-shaped cavity having spaced opposed friction surfaces on the opposed walls of the cavity. The side walls of the housing and the outer annular base wall thereof each have a multiplicity of openings and each have fins formed thereon. A stator portion includes an annular base member mounting a first annular piston within the cavity, the first piston carrying an annular flange overlying the mounting to form an annular cylinder within the annular cavity. A second annular piston is mounted in the cylinder with springs for normally urging the pistons together with friction rings carried by each of the pistons for engagement with the friction surfaces of the U-shaped cavity. Also, bearings rotatably mount the rotor on the stator together with a bracket maintain the stator stationary, and springs are mounted on the stator for a spring return of the brake.</p> |
