Abstract
This invention relates to a drive coupling for connecting an output shaft such as for a motor to an input pinion such as for a reducer. A coupling member which has an intermediate portion supported for rotation in bearings in a bracket which is mounted on a motor. The coupling member has one end portion in the form of a slotted sleeve which extends about the motor shaft and is clamped thereto by a clamping collar. The other end of the coupling member is provided with a bore for receiving a pinion shaft in a force-fit relationshp. The pinion shaft may be pinned to the coupling member by means of a spiral pin and the slotted sleeve may be keyed to the motor output shaft by means of a suitable slot and key arrangement.
Claims17
A drive coupling for connection to an output shaft of drive means, said coupling comprising;
- a bracket adapted for securement to the drive means;
- a coupling member rotatably received within said bracket, including a first end portion defining a sleeve for securement to the output shaft, said sleeve defining at least one elongated slot therethrough, and said member further including an opposite end portion defining a coupling output shaft adapted for coupling to a pinion shaft;
- and
- clamping means received about said sleeve for tightening same about the drive means output shaft.
A drive coupling for connection to an output shaft of drive means, said coupling comprising;
- a bracket adapted for securement to the drive means;
- a coupling member rotatably received within said bracket, including a first end portion defining a sleeve for securement to the output shaft, said sleeve defining at least one elongated slot therethrough, and said member further including an opposite end portion defining a coupling output shaft;
- and
- means received about said sleeve for tightening same about the drive means output shaft;
- wherein
- said opposite end portion of said coupling member has a pinion shaft bore for receiving the shaft of a pinion in a force-fit relationship, and the drive means comprises a C-face electric motor;
- and further wherein
- said pinion shaft bore extends the length of said coupling member so as to communicate with said first end portion sleeve thereof to permit a pinion shaft received in said pinion shaft bore to be loosened therefrom by a rod inserted in said sleeve and directed along said extended bore towards said opposite end portion of said coupling member.
A drive coupling for connection to an output shaft of drive means, said coupling comprising;
- a bracket adapted for securement to the drive means;
- a coupling member rotatably received within said bracket, including a first end portion defining a sleeve for securement to the output shaft, said sleeve defining at least one elongated slot therethrough, and said member further including an opposite end portion defining a coupling output shaft;
- and
- means received about said sleeve for tightening same about the drive means output shaft;
- wherein
- said opposite end portion of said coupling member has a pinion shaft bore for receiving the shaft of a pinion in a force-fit relationship, and the drive means comprises a C-face electric motor;
- and further wherein
- the pinion shaft is pinned to said opposite end portion for rotation therewith.
A drive for a pinion comprising:
- (a) motor means having an output shaft;
- (b) a bracket supported by said motor means and adjacent to said output shaft thereof;
- (c) bearing means supported on said bracket;
- (d) a coupling member having an intermediate portion supported for rotation in said bearing means, a first end portion comprising a sleeve having at least one slot therein and disposed about the end of said motor shaft, and another end portion having a pinion shaft bore for receiving a pinion shaft integral with said input pinion;
- (e) a clamping collar disposed about said sleeve for clamping said sleeve to said motor output shaft and centered thereabout;
- and
- (f) an input pinion having integral therewith a pinion shaft disposed within said pinion shaft bore of said another end portion of said coupling member.
A drive shaft for a pinion comprising:
- (a) motor means having an output shaft;
- (b) a bracket supported by said motor means and adjacent to said output shaft thereof;
- (c) bearing means supported on said bracket;
- (d) a coupling member having an intermediate portion supported for rotation in said bearing means, a first end portion comprising a sleeve having at least one slot therein and disposed about the end of said motor shaft, and another end portion having a pinion shaft bore for receiving a pinion shaft integral with said input pinion;
- (e) a clamping collar disposed about said sleeve for clamping said sleeve to said motor output shaft and centered thereabout;
- and
- (f) an input pinion having integral therewith a pinion shaft disposed within said pinion shaft bore of said another end portion of said coupling member;
- wherein
- said pinion shaft is pinned to said another end portion for rotation therewith.
