Abstract
A fixture for use in mounting an accessory on the frame of an engine or mine and adapted for adjustments for aligning a shaft of the accessory with a power take-off shaft of the machine. The fixture comprises a housing in two parts, one of which is adapted for attachment to the frame of the engine and the other is adapted to receive the accessory. The housing includes means for angularly and laterally positioning the accessory shaft for aligning it in concentricity with the power take-off shaft.
Claims15
A fixture for use in mounting an accessory on a machine and adapted for adjustments for aligning a shaft of the accessory with a power take-off shaft extending from the machine comprising:
- a housing in two parts;
- a first part adapted to be attached to the frame of the machine and surrounding the power take-off shaft on the machine coaxially therewith;
- a second part carried outboard of the first part and adapted to receive an accessory having a shaft extending axially of the second part and directed toward the power take-off of the machine;
- said first and second parts obliquely mounted with respect to their axis so that upon selective rotation of the second part its axis may be angularly positioned with respect to the first part;
- means on the second part for selectively positioning the accessory so that the axis of its shaft may be selectively adjusted laterally;
- whereby upon adjustments the axis of the accessory shaft is adapted to be shifted angularly and laterally for alignment with the axis of the power take-off shaft.
A fixture for use in mounting an accessory on a machine and adapted for adjustments for aligning a shaft on the accessory with a power take-off shaft on the machine comprising:
- a housing including a first part rotatably carrying a shaft connector and adapted to be mounted on the frame of the machine with the connector drivingly secured to the power take-off shaft in axial alignment therewith;
- PG,12
- said housing including a second part in the form of a ring mounted outboard which is adapted to mount an accessory with a shaft thereof extending inwardly for axial connection with the connector;
- said first and second parts mounted on mating surfaces disposed at oblique angles with respect to their axis so that upon selective rotational adjustment of the second part its axis may angularly disposed into alignment or parallelism with the axis of the first part;
- said second part including means for selectively adjusting the accessory so that the axis of its shaft may be shifted laterally with respect to the axis of the second part;
- whereby upon rotational adjustment of the second part and lateral adjustment of the accessory on the second parts the axis of the accessory shaft may be brought into alignment with the connector for attachment and transmitting of rotary power.
The method of mounting an accessory on an engine and aligning its shaft with a power take-off shaft on the engine comprising:
- mounting an adjustable fixture on an engine surrounding the power take-off shaft;
- mounting an accessory on the fixture with its shaft extending generally toward the power take-off shaft;
- adjusting the fixture for angularly positioning the axis of the accessory shaft parallel to the axis of the power take-off shaft;
- and
- shifting the accessory on the fixture for moving its shaft laterally whereby its axis is moved from parallelism to concentricity with the power take-off shaft.
