Abstract
A reducer of an electric power steering apparatus is disclosed. It reduces rattle noise generated by a backlash due to friction and wear of a worm and a worm wheel or an impact transmitted from a road surface through a wheel and a steering shaft and enhances a steering feeling of a driver by improving the catching phenomenon and rotational resistance generated between a worm shaft and a worm shaft bearing.
Claims8
A reducer of an electric power steering apparatus adapted to absorb vibrations and noise generated when a worm shaft is moved in an axial direction thereof or resiliently deformed at a certain angle from the axial direction, comprising:
- a guide configured to axially support a worm shaft bearing coupled to an end of a worm shaft opposite to a coupling portion of a motor shaft;
- a guide damper coupled to the guide and configured to provide the guide with an axial resilient force;
- and
- an adjusting plug coupled to one side of a gear housing so as to pass through the gear housing and configured to adjust a support force of the guide damper while axially supporting the guide damper.
