Abstract
A rapid coupling for a supported, driven shaft is disclosed. The coupling includes a coupling sleeve which is axially slidable over a drive shaft but keyed to the drive shaft to ensure that the coupling sleeve rotates with the shaft. The coupling sleeve has a driven end which includes slots for engaging driven pins affixed to a driven shaft. The coupling sleeve slides over and supports the driven shaft in a coupled position. The coupling sleeve is held in the coupled position by a quick release pin received in a bore through the drive shaft. The advantage is a simple coupling that is easily manufactured, the coupling being serviceable in a very restricted space where the driven shaft must be uncoupled without axial movement of either shaft.
Claims15
A rapid coupling for coupling a drive shaft to a driven shaft, comprising:
- a coupling sleeve having a drive end with an end face, a driven end with an end face and an axial bore that extends from the drive end to the driven end and is sized to accommodate the drive shaft and the driven shaft and be axially slidable over the shafts, the driven end including slots for receiving driven pin ends affixed to the driven shaft;
- key means for connecting the coupling sleeve to the drive shaft for rotation therewith, the key means permitting axial movement of the coupling sleeve while inhibiting rotational movement of the coupling sleeve on the drive shaft, at least one key way cooperating with the key means to permit axial movement of the coupling sleeve, the key way extending from the end face of the drive end to the end face of the driven end of the coupling sleeve;
- and
- locking means associated with the drive shaft for locking the coupling sleeve in a coupled position wherein the coupling sleeve receives an end of the driven shaft, the driven pin ends are received in the slots and the driven shaft is axially rotated with the drive shaft.
A rapid coupling for coupling a drive shaft to a driven shaft supported by the drive shaft, comprising:
- a coupling sleeve having a drive end with an end face, a driven end with an end face and an axial bore that extends from the drive end to the driven end and is sized to accommodate the drive shaft and the driven shaft in an axially slidable relationship, the driven end including slots for receiving driven pin ends affixed to the driven shaft;
- a pin for connecting the coupling sleeve to the drive shaft for rotation therewith, the pin being received in a radial bore through the drive shaft and extending beyond a periphery of at least one side of the drive shaft, the pin engaging at least one key way in a wall of the axial bore in the coupling sleeve, the key way extending from the end face of the drive end to the end face of the driven end the coupling sleeve, thus permitting axial movement of the coupling sleeve while inhibiting rotational movement of the coupling sleeve on the drive shaft;
- and
- locking means associated with the drive shaft for locking the coupling sleeve in a coupled position wherein the coupling sleeve receives an end of the drive shaft, the driven pin ends are received in the slots and the driven shaft is supported for axial rotation with the drive shaft.
A rapid coupling for coupling a drive shaft to a driven shaft supported by the drive shaft, comprising:
- a coupling sleeve having a drive end with an end face, a driven end with an end face and an axial bore that extends from the drive end to the driven end and is sized to accommodate the drive shaft and the driven shaft and be axially slidable on the shafts, the driven end including slots for receiving driven pin ends affixed to the driven shaft;
- a pin for connecting the coupling sleeve to the drive shaft for rotation therewith, the pin being received in a radial bore through the drive shaft and extending beyond a periphery of each side of the drive shaft, the pin engaging opposed key ways in a wall of the axial bore in the coupling sleeve, the key ways extending from the end face of the drive end to the end face of the driven end of the coupling sleeve, thus permitting axial movement of the coupling sleeve on the drive shaft while inhibiting rotational movement of the coupling sleeve on the drift shaft;
- and
- a bore and pin combination associated with the drive shaft for locking the coupling sleeve in a coupled position wherein the coupling sleeve receives an end of the driven shaft, the driven pin ends are received in the slots and the driven shaft is supported for axial rotation with the drive shaft, the bore being an axial bore through the drive shaft located in an exposed position adjacent the drive end of the coupling sleeve when the coupling sleeve is in the coupled position.
