Abstract
Disclosed is a reducer of an electric power steering apparatus. In the reducer, the worm wheel is elastically supported by the elastic member in a direction to the worm wheel in order to compensate for the spacing between the worm shaft and the worm wheel, and an elastic force of the elastic member applied to the bearing bush or the worm shaft bearing is simply adjusted and measured by adjusting or measuring a load applied to the supporting member.
Claims11
A reducer of an electric power steering apparatus, the reducer comprising:
- a worm shaft bearing mounted on a distal end of a worm shaft which is tooth-engaged with a worm wheel and is connected to a motor shaft;
- a bearing bush having a side opened in an axial direction, in which the worm shaft bearing is inserted and supported, and an outer peripheral surface supported on an inner peripheral surface of a gear housing;
- an elastic member having one end thereof supported by the bearing bush or the worm shaft bearing so as to elastically support the worm shaft in a direction to the worm wheel;
- a supporting member coupled to the other end of the elastic member, in which an elastic force applied by the elastic member to the bearing bush or the worm bearing is adjusted and measured through an adjustment and a measurement of a load applied to the supporting member;
- and
- a hollow adjustment member in which the supporting member is inserted and supported, and coupled to the gear housing.
