WORMSHAFT DAMPING APPARATUS OF ELECTRIC POWER STEERING

摘要

In order to effectively absorb the shock of a worm shaft, the present invention comprises a worm shaft which is connected to a worm wheel inside a housing using the gears to be rotated and which has a bearing at both ends to support the rotation of the worm shaft; a first plate with one side to come in contact with one or both outer wheels of the bearing by corresponding them; a shock absorbing member which is made of an elastically deformable material, of which one side comes in contact with the other side of the first plate by corresponding it, and which has intermittent elastically deformable grooves having a predetermine depth on the inner and outer circumferences; and a second plate to come in contact with the other side of the shock absorbing member by corresponding it.
