Reducer including planetary gear and steering apparatus for vehicle including the same

摘要

The present invention relates to a reducer including a planetary gear and a steering apparatus of a vehicle including the same, and more particularly to a reducer including a planetary gear which can compensate a gap generated by wear of gear teeth of planet gears, sun gears, and ring gears, and a steering apparatus of a vehicle including the same.

主权项

1. A reducer for a steering apparatus of a vehicle comprising:
a sun gear coupled to a hollow motor shaft; a plurality of first planet gears circumscribed about the sun gear and inscribed in a first ring gear that is coupled and fixed to an inner peripheral surface of a housing; a plurality of second planet gears inscribed in a second ring gear to which a pinion shaft, which is inserted into the hollow motor shaft, is coupled, the plurality of second planet gears being connected to the first planet gears via connecting shafts; a carrier, through which the pinion shaft passes, having coupling holes such that the connecting shafts pass through and are coupled to the coupling holes, in which a distance from the center of the carrier to the center of a first coupling hole of the coupling holes and a distance from the center of the carrier to the centers of the remaining coupling holes are different; and a first resilient member coupled between a first connecting shaft among the connecting shafts and the first coupling hole, wherein the first connecting shaft is inserted into the first coupling hole.
