Abstract
A gear train is provided that includes at least one side gear comprising a helical face gear and a plurality of helical pinions in meshing engagement with the helical face gear. The gear train may further include an absorber configured to provide an axial force on at least one of the plurality of helical pinions. A differential may also be provided including a differential case and a gear train disposed in the differential case. The gear train includes at least one side gear comprising a helical face gear and a plurality of helical pinions in meshing engagement with the helical face gear. The gear train in the differential may further include a means for providing an axial force on at least one of the plurality of helical pinions.
Claims17
A gear train, comprising:
- at least one side gear comprising a helical face gear;
- a plurality of helical pinions in meshing engagement with the helical face gear;
- a first absorber configured to directly engage a first end of at least one of the plurality of helical pinions, the first absorber configured to provide an axial force on the at least one of the plurality of helical pinions in a first direction;
- and
- a second absorber configured to directly engage a second end of the at least one of the plurality of helical pinions, the second absorber configured to provide an axial force on the at least one of the plurality of helical pinions in a second direction opposing the first direction.
A differential, comprising:
- a differential case;
- and
- a gear train disposed in the differential case, the gear train comprising:
- at least one side gear comprising a helical face gear;
- a plurality of helical pinions in meshing engagement with the helical face gear;
- a first means configured to directly engage a first end of at least one of the plurality of pinions for providing an axial force on at least one of the plurality of pinions in a first direction;
- and
- a second means configured to directly engage a second end of the at least one of the plurality of pinions for providing an axial force on the at least one of the plurality of pinions in a second direction opposing the first direction.
