Abstract
Provided is a reducer of an electric power steering apparatus. The reducer has a significantly reduced volume, a decreased number of components, and a shortened production process and can prevent vibration and noise generated during power transfer while removing noise caused by a clearance between a shaft and a power transfer member.
Claims14
A reducer of an electric power steering apparatus in which a first shaft and a second shaft are connected to each other to transfer driving force of a driving motor, the reducer comprising:
- an inner rotor including an insertion hole formed axially with respect to the second shaft and a first protrusion formed radially with respect to the second shaft;
- an elastic body formed to surround an outer circumferential surface of the inner rotor, the elastic body including a second protrusion formed radially with respect to the second shaft and an elastic protrusion formed on the second protrusion axially with respect to the second shaft;
- and
- an outer rotor coupled to the inner rotor, the outer rotor including a third protrusion coupled to the first shaft and formed radially with respect to the second shaft.

A reducer of an electric power steering apparatus, the reducer comprising:
- a first shaft having at least one protrusion provided at an outer circumferential surface;
- a second shaft having at least one axial extension at one end;
- and
- a power transfer member having a first coupling part including an insertion hole, into which the protrusion is to be inserted so that the first shaft is coupled to the first coupling part, in a center area, and a second coupling part, on which the extension is to be mounted so that the second shaft is coupled to the second coupling part, on an outer circumferential surface.
