US Patent:

40474526, Sep 13, 1977

Filed:

Mar 15, 1976

Appl. No.:

5/667022

Inventors:

Robert Truman Eddy - South Bend IN

Assignee:

Reliance Electric Company - Mishawaka IN

International Classification:

F16H 374

US Classification:

74752C

Abstract:

A drive mechanism for a belt conveyor system having a driven pulley and a belt trained thereon, the mechanism including a speed reducer disposed in the pulley and having coaxial input and output shafts, the output shaft being a reaction shaft for the rotatable housing of the speed reducer. The housing of the speed reducer is in axial alignment with the pulley and is connected thereto for driving the pulley. A brake is provided for restraining the rotation of the output shaft, and may consist of a disc rotatable with the output shaft and a hydraulically operated head controlled by a system including a pump driven by the output shaft in response to the load on the belt of the conveyor. The drive for the pump senses the load on the conveyor belt by the reaction response of the output shaft, thereby varying the rate at which the pressure in the hydraulic system increases to control the friction head indirectly in response to the conveyor load. A second brake, which may be a disc type with a hydraulically operated caliper head, is preferably included for controlling the conveyor system.

International Classification:

F01b 1306

US Classification:

Abstract:

A hydraulic device which is primarily intended for use as a motor, includes an annular stator having an internal cam surface consisting of a plurality of outwardly and inwardly extending reaction surfaces, and a rotor disposed within said stator having a plurality of open-ended fluid pressure chambers with a rolling element therein engaging the outwardly and inwardly extending reaction surfaces and extending the width of the rotor. The rotor is mounted on a shaft and when operating as a motor is rotated by the rolling elements reacting on the outwardly extending reaction surfaces to rotate the shaft. Fluid inlet and outlet passages are disposed in a port plate disposed along the side of the rotor and communicate with the fluid pressure chambers through one of their open ends.
