PLANETARY GEAR SYSTEM

摘要

A planetary gear system with floating components includes design features that center the floating components radially and reduces sagging of the floating components under the force of gravity. An input carrier is centered by the use of an annular bearing in a distal central opening of the input carrier and a stationary end cap assembly that is received in the annular bushing. The bushing and end cap assembly support the input carrier radially. The stationary output carrier is centered by providing a pilot on the output carrier that is received in a circumferential recess in a fixed component, such as a reaction hub.

1. A planetary gear system connected to a fixed component, the planetary gear system comprising:
an input component having a primary axis and coupled to an input gear set, the input gear set meshed with an input set of teeth of a ring gear that surrounds the input gear set; the ring gear including an output set of teeth, the output set of teeth meshed with at least one output planet gear, the at least one output planet gear rotatably coupled to a stationary output carrier; and the stationary output carrier coupled to the fixed component with a tongue in groove connection that is transverse to the primary axis.
