, it so can also avoid the problem of hysteresis be present between retainer and spring abutting plate, so as to also it is prevented that ripple
Spring abuts the problem of plate slides with retainer and spring, and then extends the service life of ripple spring.
Preferably, the spring abuts is provided with breach between plate and power transmission shaft.
By using above-mentioned technical proposal, due to also having the effect extruded, institute with spring to meet that spring abuts plate pair
Abutting plate with spring can typically be made into than relatively thin state, and spring compresses the breach opened up between plate and power transmission shaft, can
Preferably facilitate spring to abut plate to deform upon, and then also just reduce spring and compress abrasion caused by between plate and power transmission shaft.
Preferably, the end that the ripple spring abuts plate with spring is connected.
By using above-mentioned technical proposal, due to spring compress plate threshold value fixing point can compare it is remote, so
During deformation, its Bending Deformation can compare obvious, and such ripple spring also can be more for the sealing compensation of rotating ring
Significantly.
Preferably, the section of the ripple spring is W fonts.
By using above-mentioned technical proposal, because W fonts are symmetrical, stress can during flexible for such spring
It is more symmetrical, so as to be also beneficial to the life-span that extension spring uses.
Preferably, the rotating ring abuts the step trough for abutting against one end and being provided with annular of plate, the step trough with spring
Interior to be provided with sealing ring, the seal ring set is located on power transmission shaft.
By using above-mentioned technical proposal, the work of sealing so can be further played to space between retainer and rotating ring
With.
Extend preferably, rotating ring direction vertically is continued in the convex edge, and abutted against with the outer surface of rotating ring.
It is fold-line-shaped by using above-mentioned technical proposal, between such retainer and rotating ring, and the extension of convex edge
Point it is what is abutted against with the outer surface of rotating ring, so can further improves the leakage efficiency between retainer and rotating ring.
Preferably, the end of the extension of the convex edge is provided with projection, and raised and step trough to rotating ring direction
It is corresponding.
By using above-mentioned technical proposal, the extension of such convex edge can bring some pressure to bear to rotating ring so that dynamic
It can be more preferably close together between ring and sealing ring, so be also beneficial to improve leakage efficiency.
In summary, the utility model has the advantages that：
1. retainer, spring and spring abut plate three and be made into integration, be so advantageous to spring relative to transmission
Seat and spring abut plate and slid, and then are advantageous to improve the service life of spring；
2. the end that ripple spring abuts plate with spring is connected, such ripple spring can for the sealing compensation of rotating ring
It is more sensitive；
3. convex edge extends to rotating ring direction, and is provided with projection in end and is abutted against with rotating ring, can so increase to rotating ring
Pressure, so as to improve the tight ness rating between rotating ring and sealing ring.
