Abstract
A rigid arm supports the outboard end of a shaft of a power driven apparatus to minimize transverse deflection of the shaft under load. The arm extends through a loop formed by a flexible drive member and permits replacement of the drive member without removal of the arm. In a preferred embodiment, the arm is a cantilevered arm of substantially rectangular cross section which is bolted or otherwise secured to the apparatus and has a bearing at its outer end which engages the output shaft.
Claims15
Power driven apparatus comprising:
- frame means;
- a primary rotary structure mounted to the frame means and having an output shaft extending along a preselected axis of rotation to a free outer end;
- a secondary structure rotatably mounted to the frame means;
- means for transmitting rotational forces between the output shaft and the secondary structure, said force transmitting means comprising at least one flexible, elongated member which forms a continuous loop;
- and
- a support device having:
- a base portion mounted to the primary structure adjacent to the output shaft;
- a rigid arm extending from the base portion and through the loop formed by the flexible member to a location adjacent the free end of the output shaft;
- and
- a bearing portion carried by the rigid arm at said location to support the free end against transverse deflection.
A device for supporting a free end of an output shaft of a primary rotary structure which is linked to a secondary structure through at least one flexible force transmitting member forming a continuous loop, comprising:
- a base portion mountable to the primary structure in a preselected operative position of the support device;
- a rigid arm extending from the base portion and through the loop formed by the force transmitting member to a location adjacent the free end of the output shaft in said operative position;
- and
- a bearing portion carried by the rigid arm at said location to support the free end against transverse deflection.
