Abstract
The disclosure relates to a shaft adjuster, in particular a camshaft adjuster, comprising a drive gear having a spur gear toothing and a clamping gear which is arranged coaxially relative to the drive gear and which is loaded by a spring acting in the circumferential direction. The spring is also designed as an axial securing element for axially securing the clamping gear on the drive gear.
Claims19
A camshaft adjuster, comprising:
- a drive gear having a spur gear toothing, and
- a clamping gear arranged coaxially relative to the drive gear, the clamping gear loaded by a spring acting in a circumferential direction, and
- the spring is configured to axially secure the clamping gear on the drive gear.
An electromechanical camshaft adjuster, comprising:
- a drive gear having a spur gear toothing, and
- a clamping gear arranged coaxially relative to the drive gear, the clamping gear biased via a torsion spring arranged within a tangential groove of the drive gear, and
- the torsion spring is configured to axially secure the clamping gear on the drive gear, and
- the clamping gear is arranged between the spur gear toothing and the torsion spring in an axial direction.
1 more element
An electromechanical camshaft adjuster, comprising:
- a drive gear having a spur gear toothing and an annular projection, and
- a clamping gear arranged on the annular projection and axially retained on the annular projection via a torsion spring configured to load the clamping gear in a circumferential direction, and
- the annular projection having:
- internal toothing configured for a harmonic drive, and
- a tangential groove configured to receive the torsion spring.
