First sealing ring.
Compared with prior art, the utility model has the advantage of: the former of stator and the consistency of thickness of rotor, make cover plate
When being fixed on stator former, simultaneously and rotor seal, former is provided with the seal groove of annular, is entered by the first sealing ring cover plate
One step makes cavity be hedged off from the outer world, and product hermeticity is good, thus reliability when improve use.
As a kind of improvement of the present utility model, described cover plate is connected with stator by circumferentially disposed multiple bolts, institute
State that the former of stator is circumferentially-spaced is distributed with multiple radially inwardly projecting fixed part fixing for bolt, described fixed part
It is provided with bolt hole, by described improvement, makes by arranging fixed part the fixed-area of bolt increase, thus can be selected for more
Big bolt is so that cover plate is fixed on the former of stator more reliably.
Also having one to improve as of the present utility model, described seal groove has installed along stator radially-inwardly at spiro keyhole position
Protrude the inner fovea part bolt hole and cavity to be cut off, by described improvement, sealing ring when sealing, by bolt hole and cavity every
Disconnected, it is to avoid fluid is revealed at bolt hole.
Also having one to improve as of the present utility model, the shape of described seal groove is consistent with bore of stator shape, passes through
Described improvement, seal groove shape shape external with bore of stator is consistent, and i.e. seal groove is along the skew of stator diametrically bore of stator body wall
Measure identical, so that hydraulic oil keeps consistent to the impulsive force of the sealing ring in seal groove, thus avoid sealing ring certain point to answer
Power is concentrated and is caused decline service life.
Also having one to improve as of the present utility model, described rotor center is provided with for rotor and the stator initial bit of resetting
The returning device put, described returning device includes the spider of the spacing heart in the rotor of circumference, is fixed on the cover plate of stator side
The plug of center and the return spring being located between spider and plug, described return spring one end limits with spider circumference
Position, the described return spring other end is spacing with plug circumference, and by described improvement, return spring provides and is used for resetting rotor with fixed
The restoring force of the relative position that son is initial.
Also have one to improve as of the present utility model, between described plug and cover plate, be provided with the second sealing for sealing
Circle, by described improvement, prevents fluid from going out to ooze out from plug, improves the sealing of dry-type belt phaser further, thus carries
The reliability of high product.
