Abstract
The utility model relates to a sealing device for a hub bearing, which comprises a framework and a sealing part. The framework is wrapped by the sealing part, one side of the sealing part is provided with at least two side sealing lips positioned on the same side of the sealing part, and one end of the sealing part is provided with two end sealing lips. By means of the technical scheme, the sealing device is capable of well preventing impurities such as dust particles, muddy water and the like form entering the hub bearing to lead to failure of the hub bearing.
Description
Technical field
The utility model relates to a kind of seal arrangement of hub bearing.
Background technique
The main effect of hub bearing is load-bearing and for the rotation of wheel hub provides accurate guiding, and it not only bears thrust load but also bear radial load, is very important component.Hub bearing is provided with outward flange, inner flange, and seal arrangement is arranged between outward flange, the inner flange.
The seal arrangement of existing a kind of hub bearing includes skeleton, is coated on the Sealing on the skeleton; The end that Sealing one side is provided with a side seal lip, Sealing also is provided with two end seal lips; Side seal lip, end seal lip are all realized sealing with the inner flange interference fit, and skeleton is processed by cold-rolled carbon steel thin plate and band, and side seal lip, end seal lip are processed by nitrile butadiene rubber; Gap location between side seal lip, end seal lip and the inner flange is added with grease; Can stop dust granule, muddy water etc. to break through the interference fit place effectively, enter into the inside of bearing, also can increase lubricating function; Reduce the friction between side seal lip, end seal lip and the inner flange, reduce the running torque of hub bearing effectively.
But the seal arrangement of this structure is owing to the gap of depositing grease between side seal lip, end seal lip and the inner flange is too small; Cause; The hub bearing running torque is excessive, and impurity such as some dust granules, muddy water can get into hub bearing inside, cause the inefficacy of hub bearing; And when the hub bearing operating mode was abominable, side seal lip, end seal lip resistance to high temperature difference and plastically deformable amount were little, and be aging in advance easily.
Summary of the invention
The purpose of the utility model: in order to overcome the defective of existing technology, the utility model provides a kind of seal arrangement of hub bearing, and it is inner to prevent well that impurity such as dust granule, muddy water from getting into hub bearing, causes the inefficacy of hub bearing.
The technological scheme of the utility model: a kind of seal arrangement of hub bearing; Include skeleton; Be coated on the Sealing on the skeleton; Sealing one side is provided with the side seal lip, and an end of Sealing also is provided with two end seal lips, and described side seal lip is at least two and all be positioned at the same side of Sealing.
Adopt technique scheme; Set up the side seal lip and can increase grease-filled gap; Can reduce the friction between side seal lip, end seal lip and the inner flange; Reduce running torque, and then it is inner to prevent well that impurity such as dust granule, muddy water from getting into hub bearing, causes the inefficacy of hub bearing.
The further setting of the utility model: described skeleton includes the bracing ring that axially is provided with along hub bearing; The inner ring plate, the outer ring plate that radially are provided with along hub bearing; Described inner ring plate, outer ring plate laterally arrange; Also including the connection that is used to connect inner ring plate, outer ring plate tiltedly encloses; Described Sealing is coated on inner ring plate, outer ring plate and connects tiltedly on the circle, and described side seal lip is positioned at outer ring plate one side, described end seal lip be positioned at inner ring plate with respect to its with is connected the other end that tiltedly encloses connection one end.
Adopt above-mentioned further setting, the skeleton of this structure can withstand shocks better, increases the rigidity of skeleton, makes that the sealing effect of Sealing is better.
Further being provided with again of the utility model: described side seal lip laterally arranges, and described side seal lip and the hub bearing angle between radially is 53 °.
Adopt above-mentioned further setting again, can increase the rebound elasticity of side seal lip effectively, reduce friction, in the hub bearing rotary course, also can effectively impurity such as dust granule, muddy water be thrown away.
The further setting of the utility model: described side seal lip, end seal lip are processed by fluorine rubber.
Adopt above-mentioned further setting, improved Sealing resistance to high temperature and resilience, prevent that effectively it is aging ahead of time.
