Abstract
Power takeoff devices (PTOs) are useful for mounting on transmissions and for performing, directly or indirectly, useful work via the mechanical energy generated by the PTO's rotatable output shaft. Systems and methods for reducing PTO gear rattle include an input gear carried on a shaft sleeve mounted on a shaft extending between opposing spaced apart walls of a PTO housing. The shaft sleeve is moveable in an axial direction along the shaft, the travel of the shaft sleeve in each direction being limited by contacting the respective wall. The shaft sleeve is biased to remain spaced apart from the walls, thereby reducing or eliminating gear rattle.
Claims13
A gear system for a power takeoff, comprising:
- a PTO housing including a first wall opposing and spaced apart from a second wall;
- a shaft extending between the first wall and the second wall;
- a shaft sleeve carried on the shaft, wherein the shaft sleeve includes opposing first and second ends;
- an input gear carried on the shaft sleeve;
- and
- a biasing mechanism positioned between the shaft sleeve and at least one of the first wall and the second wall, wherein the biasing mechanism biases the shaft sleeve away from the at least one of the first wall and the second wall;
- wherein the shaft sleeve is axially moveable along the shaft between the first wall and the second wall;
- and
- wherein the biasing mechanism includes a first component positioned between the first end and first wall and a second component positioned between the second end and the second wall.
A gear system for a power takeoff, comprising:
- a PTO housing including a first wall opposing and spaced apart from a second wall;
- a shaft extending between the first wall and the second wall;
- a shaft sleeve carried on the shaft;
- an input gear carried on the shaft sleeve;
- and
- a biasing mechanism positioned between the shaft sleeve and at least one of the first wall and the second wall, wherein the biasing mechanism biases the shaft sleeve away from the at least one of the first wall and the second wall;
- wherein the shaft sleeve is axially moveable along the shaft between the first wall and the second wall;
- wherein at least one of the shaft sleeve and the PTO housing include a cavity, and wherein the biasing mechanism is positioned at least partially within the cavity.
A gear system for a power takeoff, comprising:
