Abstract
The present disclosure relates to a cam phase adjuster. The cam phase adjuster comprises a stator, a sprocket wheel and a cushioning ring, wherein the sprocket wheel radially protrudes from an outer side face of the stator, and the cushioning ring surrounds the outer side face of the stator. The stator and/or the sprocket wheel comprise(s) a trench feature region, which is formed on a surface, a plurality of trenches extending obliquely in a circumferential direction are formed in the trench feature region, and the cushioning ring is bonded to the trench feature region. The cam phase adjuster of the present disclosure is easy to produce.
Claims20
A cam phase adjuster, comprising:
- a stator,
- a sprocket wheel, and
- a cushioning ring, and
- the sprocket wheel radially protrudes from an outer side face of the stator, and the cushioning ring surrounds the outer side face of the stator, and
- at least one of the stator or the sprocket wheel comprises a groove feature region formed on a surface, the groove feature region comprising a plurality of grooves extending obliquely with respect to a circumferential direction, and the cushioning ring is bonded to the groove feature region.
A cam phase adjuster, comprising:
- a stator having:
- a sprocket wheel, and
- a radial outer surface axially adjacent to the sprocket wheel, the radial outer surface having a plurality of grooves extending:
- i) axially from an axial face of the stator, and ii) radially inwardly from the radial outer surface, and
- a cushioning ring extending circumferentially around the radial outer surface and bonded to the plurality of grooves.
A method for manufacturing a stator for a cam phaser, the method comprising forming the stator via a powder metallurgy process so as to simultaneously form a sprocket wheel and a grooved radial outer surface separate from the sprocket wheel, the grooved radial outer surface configured to receive an elastomeric cushioning ring.
