Specific embodiment
A specific embodiment of the invention is described in detail below with reference to Figure of description.It needs to illustrate
It is, in the present invention, unless otherwise specified, axial direction that is axial, radially and circumferentially referring respectively to stretcher, radially and circumferentially；Axis
Refer to that the top of Fig. 1 b, Fig. 2 a and Fig. 2 b, the axial other side refer to the lower section of Fig. 1 b, Fig. 2 a and Fig. 2 b to side.
As shown in Figure 2 a, the decoupling type stretcher of the basic structure and the prior art of stretcher according to the present invention is basic
Structure is identical, and the two is the difference is that space of the stretcher according to the present invention between rotating part 1 and fixed part 2
Cartridge seal structure 6 is provided in G.
In the same manner as the structure of the decoupling type stretcher of the prior art, stretcher according to the present invention include rotating part 1,
Fixed part 2 and the bearing being arranged in the circular space G between rotating part 1 and fixed part 2 (oscillation bearing 3 and
Axial bearing 4), rotating part 1 be installed on fixed part 2 and can around fixed part 2 axis relative to 2 turns of fixed part
Dynamic, the radial outside ora terminalis of axial bearing 4 is provided with sealing element 5.In the present embodiment, stretcher further includes cartridge seal knot
Structure 6, the cartridge seal structure 6 are set at an axial side opening G2 for the top towards Fig. 2 a of space G.
As shown in Figure 2 a and 2 b, cartridge seal structure 6 include be fixed on rotating part 1 shell 11 dust ring 61,
It is fixed on the sealing 62 of the sleeve 22 of fixed part 2 and is attached to the wavy rubber 63 of the radial outer side of dust ring 61,
Wherein sealing 62 includes two contact seal lips (the first contact seal lip that dust ring 61 is extended to from fixed part 2
621 and the second contact seal lip 622).Further, since processing and manufacturing needs and setting connector such as rivet
Reason, the shell 11 of rotating part 1 are formed with the multiple lug bosses 12 protruded towards fixed part 2, multiple 12 court of lug boss
To radially inner side protrusion and multiple lug bosses 12 are arranged between two adjacent lug bosses 12 with being circumferentially spaced
Form notch.Dust ring 61 is fixed on multiple lug bosses 12, to cover the interval between multiple lug bosses 12 from axial side.
In the present embodiment, dust ring 61 is made of metal, and dust ring 61 circumferentially continuously extends on complete cycle.
As shown in Figure 2 b, dust ring 61 includes along the radial R dust ring radial component 611 extended and from the dust ring radial component
The 611 radial outside end dust ring axial component 612 that axially A extends towards axial side.In the present embodiment, prevent
Dirt ring 61 is fixed on rotating part 1 by interference fit, as shown in Figure 2 a, when dust ring 61 is fixed on the shell of rotating part 1
When 11, dust ring radial component 611 is connected to lug boss 12 from axial side, and dust ring axial component 612 is passed through from radially inner side
The inner surface of shell 11 is connected to by wavy rubber 63, so that dust ring radial component 611 and following sleeve radial components 221
Opposite and dust ring axial component 612 and following sleeve axial components 222 are opposite.
In the present embodiment, wavy rubber 63 circumferentially continuously extends on complete cycle and is attached to by vulcanization
The radial outer side of dust ring axial component 612.The radial outer side of the wavy rubber 63 has to be alternately arranged on axial A
Protrusion 631 and recess portion 632 and formed wave-like.Specifically, as shown in Fig. 2 b and Fig. 2 c, the diameter of the wavy rubber 63 is outside
Totally three recess portions 632 that side is formed with totally four protrusions 631 and is formed between adjacent every two protrusion 631.Therefore, exist
In the case that the inner surface of shell 11 has irregular shape due to processing needs and setting parting line, dust ring axial component
612 can be in close contact via the inner surface of the wavy rubber 63 and shell 11 so that improve dust ring axial component 612 with
Sealing effect between the shell 11 of rotating part 1.
In the present embodiment, sealing 62 is made of rubber, and sealing 62 circumferentially continuously extends on complete cycle,
Sleeve 22 is fixed in the vulcanization of sealing 62.Sleeve 22 includes along the radial R sleeve radial component 221 extended and from the set barrel dliameter
To the radially inner side end sleeve axial component 222 that axially A extends towards the axial other side of part 221, sealing 62 is solid
Due to the part including radial outside end of sleeve radial component 221.
The first contact seal lip 621 in two contact seal lips of sealing 62 is approximately along radial R towards diameter
Extend to dust ring axial component 612 outward, the second contact seal lip 622 in two contact seal lips approximately along
Axial A extends to dust ring radial component 611 towards the axial other side, so that the first contact seal lip 621 and the second contact
Formula sealing lip 622 is connected to dust ring 61, to realize contact seal.More specifically, the first contact seal lip 621 exists
Extend while extension towards radial outside towards axial side, the second contact seal lip 622 prolongs towards the axial other side
Extend while stretching towards radial outside.In this way, the two contact seal lips 621,622 can above be mentioned in axial A and radial direction R
For good sealing effect, wherein the second contact seal lip 622 can be considered as primary seal lip.
It is used in addition, being surrounded between the first contact seal lip 621, the second contact seal lip 622 and dust ring 61
Accommodate the oil pocket S of grease.Grease is filled in oil pocket S.On the one hand, grease can be improved the sealing effect of cartridge seal structure 6
Fruit；On the other hand, grease can be between the first contact seal lip 621 and the second contact seal lip 622 and dust ring 61
Contact site be lubricated.
By using above-mentioned scheme, pollutant can be effectively prevented by cartridge seal structure 6 from the close of space G
An axial side opening G2 for oscillation bearing 3 enters the inside of space G, and the sealing effect of the cartridge seal structure 6 is steady for a long time
It is fixed effective.
Although technical solution of the present invention is explained in detail in above specific embodiment, also need to illustrate
:
1. although illustrate that the sealing 62 of cartridge seal structure 6 includes two contacts in above specific embodiment
