Abstract
A sun gear apparatus includes an axle, a sun gear rotatably supported around the axle, and a sun gear guide ring disposed between an inner peripheral surface of the sun gear and the axle. The sun gear guide ring minimizes or eliminates looseness in the coupling between the sun gear and the axle.
Claims38
A sun gear apparatus comprising:
- an axle;
- a first sun gear rotatably supported around the axle;
- and
- a first sun gear guide ring nonrotatably fixed to the axle between an inner peripheral surface of the first sun gear and the axle, wherein the first sun gear guide ring is unshiftable in an axial direction, wherein the first sun gear guide ring includes at least one of a locking projection and a locking groove that engages a corresponding at least one of a locking groove and locking projection disposed on the axle to nonrotatably fix the first sun gear guide ring to the axle, wherein the first sun gear guide ring does not form a part of another sun gear.
