REDUCER OF ELECTRIC POWER AUXILIARY STEERING APPARATUS

摘要

Disclosed is a reducer of an electric power auxiliary steering apparatus. According to embodiments of the present invention, impulse noise of a worm shaft bearing caused by fluctuation of a worm shaft can be reduced, and strength of a damping member in a direction toward a worm wheel and an opposite direction thereto is lower than that in other directions, so that the fluctuation of the worm shaft can be more effectively alleviated.

主权项

1. A reducer of an electric power auxiliary steering apparatus, comprising:
a damping member comprising an inner race and an outer race, wherein the inner race is mounted on an outer peripheral surface of a worm shaft bearing coupled to one end of a worm shaft engaged with a worm wheel, a motor shaft being coupled to the other end of the worm shaft, and the outer race is connected with connection parts formed at one portion orienting toward the worm wheel and an opposite portion thereto, respectively, of an outer peripheral surface of the inner race, provided around the inner race, and supported on an inner surface of a gear housing; and a bush member provided between the inner race and the outer race, and formed with through holes through which the connection parts pass, respectively, in a direction toward the worm wheel and an opposite direction thereto.
