REDUCER OF ELECTRIC POWER STEERING APPARATUS

摘要

Discloses is a reducer of an electric power steering apparatus. The reducer of the electric power steering apparatus can reduce the rattling noise caused by an increase of backlash due to friction and abrasion of a worm and a worm wheel or by an impact transferred through a wheel and a steering shaft from the road and allowing a pivotal movement of a worm shaft, while decreasing a rotation resistance and blockage of a worm shaft and a worm shaft bearing to increase steering feel of a driver.

主权项

1. A reducer of an electric power steering apparatus, the reducer comprising:
a worm shaft bearing mounted on one end of a worm shaft connected to and proximal to a motor shaft; a damper which encloses both sides and an outer race of the worm shaft bearing, for providing an elastic force to the worm shaft bearing in axial and radial directions; and a plug bolt which is coupled to a gear housing, for supporting an outer peripheral surface and a side end of the damper in the axial and radial directions.
