Abstract
Disclosed is a step actuator. The step actuator includes a housing; a stator installed in the housing; a rotor positioned radially inward from the stator, the rotor rotating and protruding from one side of the housing; a bearing installed at one side of the housing so as to be coupled with the rotor; a bearing cover coupled with one side of the housing to restrain movement of the bearing; a screw member coupled with the rotor to linearly move according to rotation of the rotor; and a mounting member coupled to the bearing cover to support the screw member.
Claims19
A step actuator comprising:
- a housing including a first housing and a second housing;
- a stator installed in the housing, wherein the stator includes a first bobbin, a second bobbin, a first yoke having a first tooth, and a second yoke having a second tooth installed between the first housing and the second housing;
- a rotor positioned radially inward from the stator, the rotor rotating and protruding from one side of the housing;
- a bearing installed at one side of the second housing;
- a bearing cover coupled with one side of the housing, wherein the bearing cover supports the bearing;
- a screw member coupled with the rotor;
- and
- a mounting member coupled to the bearing cover,
- wherein the first housing includes a third tooth protruding toward the second housing so as to be disposed between the first bobbin and the magnet by passing through a slit of the first bobbin,
- wherein the second housing includes a fourth tooth protruding toward the first housing so as to be disposed between the second bobbin and the magnet.

A step actuator comprising:
- a housing;
- a stator installed in the housing;
- a rotor positioned radially inward from the stator, the rotor rotating and protruding from one side of the housing, wherein the rotor includes a magnet installed within the stator to rotate while interacting with the stator and a nut member coupled to the magnet, wherein a spline is provided at an outer peripheral surface of the nut member, wherein the spline extends in an axial direction and coupled with an spline hole formed in the magnet;
- a bearing installed at one side of the housing;
- a bearing cover coupled with one side of the housing, wherein the bearing cover supports the bearing;
- a screw member coupled with the nut member to linearly move in a first direction and a second direction, which is opposite to the first direction, according to rotation of the rotor;
- and
- a mounting member detachably coupled to the bearing cover.
