When the circular runout of wheel bearing is not too large, several grooves can be only set, a groove and its position are especially only set
Such as positioned at the centre of axial lip, without using having larger-diameter elastic component, saving material.In addition, this set
Meter also relaxes the size requirement to elastic component.
According to other embodiment of the present utility model, elastic component is spring, especially annular single-coil spring.
According to other embodiment of the present utility model, multiple axial directions are set in the cavity between skeleton and dust cap
Lip, elastic component as described above is set on the lip of at least one of which axial direction.These axial lips all can be fixed on skeleton,
And abreast axially extend towards dust cap and formed with dust cap and sealed, or wherein at least one axial direction lip is fixed
Extend on dust cap and towards skeleton and formed with skeleton and sealed, or one of them axial lip is fixed on skeleton and court
Extend to dust cap, and other in which axial direction lip is fixed on dust cap and extended towards skeleton, the two axial lips exist
Be in contact in cavity and formed sealing pair.One or more grooves as described above can be set on above-mentioned axial lip.
According to other embodiment of the present utility model, footpath labiad is set in the cavity, the footpath labiad along
Radially extend and form sealing with the axial segment of the dust cap.The footpath labiad can have similar set to axial lip
Meter, such as multiple footpath labiads are set in the cavity, such as one or more grooves are set on the labiad of footpath.
It is according to the advantages of embodiment of the present utility model：
1. make it that the cartridge seal device for wheel bearing is compacter；
2. improving the sealing of cartridge seal device, it is contaminated to be better protected from oil medium；
3. can not only under high pressure and can be with larger bounce according to sealing structure of the present utility model
In the case of work well.
