Ground is against the end face of gear ring, so that gear ring is axially retained in shell.
Currently, common retaining ring is opening design.Based on application size, attaching/detaching method and manufacturing capacity come
Calculate the gap of retaining ring.However, at work, which will cause gear ring axial movement, thus gear ring and retaining ring it
Between generate vibration and tap, to cause Vehicular vibration noise (NVH) penalty.
Retaining ring is generally made of steel, it is impossible to have the damping function for absorbing vibration, reducing noise.
Therefore it currently urgently develops a kind of can absorb vibrate, reduce noise, and can be between effective compensation gear ring and retaining ring
The retaining ring axially retained.
Summary of the invention
To realize object above, the present invention adopts the following technical scheme:
The present invention provides a kind of retaining ring for axially retaining in the housing gear ring, and the retaining ring has opening,
And the surface of the end face against the gear ring of the retaining ring is provided with damping structure.
In one embodiment, the damping structure has semi-circular cross-section.
In one embodiment, the damping structure has quadrangular section.
In one embodiment, the damping structure passes through the institute by damping material with adhesive bonding to the retaining ring
It states surface and is formed.
In one embodiment, the damping structure is attached to the retaining ring by way of by damping material vulcanization
The surface and formed.
In one embodiment, the damping structure is arranged in the whole surface on the surface of the retaining ring.
In one embodiment, the damping structure is arranged in the part of the surface on the surface of the retaining ring.
In one embodiment, the damping structure is formed by elastomer.
In one embodiment, the surface opposite with the surface against the gear ring of the retaining ring is in radial side
To outside chamfering is set, the chamfering is for compensating axially retaining between the gear ring and the retaining ring.
In one embodiment, the chamfering is 15 degree.
Compared with prior art, the present invention provides a kind of retaining ring axially retained with damping function and compensation, make
Of the invention it must can obtain following technical effect:
1) damping structure is arranged in the end face of retaining ring side, absorbs the vibration generated between gear ring and retaining ring, reduces
Noise, to improve Vehicular vibration noise (NVH) performance.
2) chamfering structure is arranged in the end face of the retaining ring other side, to compensate for the axial direction between compensation gear ring and retaining ring
It keeps.
