Abstract
The invention belongs to the field of bearings, and relates to a bearing and a seal assembly thereof, in particular to a high-temperature bearing and a seal assembly thereof. The existing seal washer with a standard structure is removed, outside diameters of a seal ring and a bearing inner ring are matched to realize sealing, the dimensions and quantity of spare parts are reduced, the angle and elastic deformation of a seal lip are designed scientifically, the sealability is not reduced, and the friction is reduced.
Description
Technical field
The present invention relates to a kind of bearing and black box thereof, specifically relate to a kind of high temperature resistant bearing and black box thereof, it belongs to field of bearings.
Background technique
The high temperature such as automobile retarder and mining equiment rotating machinery is more and more stricter to the requirement of heat-resisting quantity, volume miniaturization with bearing.At present, the high temperature resistant bearing that automobile retarder and mining equiment etc. generally use adopts the structure of bearing, seal washer and seal ring, and it takes up room greatly, and each element size is large, and number of spare parts is many; More and more can not satisfy automobile retarder and mining equiment etc. to the requirement of high temperature resistant bearing.
Summary of the invention
Problem in view of prior art exists the objective of the invention is to provide a kind of high temperature resistant bearing of new structure and black box that is applied to the rotation class mechanical structure of high temperature high leak tightness.
To achieve these goals, the technical solution adopted in the present invention is high temperature resistant bearing and black box thereof, it comprises: housing, axle rubber body, shield bearing and seal ring, shield bearing is installed between housing and the axle rubber body, housing and axle rubber body directly are sealed into one, the shield bearing top is provided with seal ring, and seal ring matches with the external diameter of bearing inner race.
Described sealing cast has metal frame and rubber ring to consist of, the rubber ring clad metal skeleton outside.
The lips structure of the full clad metal skeleton of described rubber ring or half clad metal skeleton.
The material of described seal ring is for adopting fluorine rubber.
The seal lip of described seal ring and the magnitude of interference of counterpart are 0.1 ~ 1.2.
The invention has the advantages that: the seal washer of present normal structure is removed, seal ring cooperates to realize sealing with the external diameter of bearing inner race, reduce element size and amount of parts, angle and the elastic deformation amount of science design sealing lip, reach and do not reduce sealing, the function of reducing friction again.
Description of drawings
Fig. 1 is the structural representation of existing high temperature resistant bearing and black box thereof;
Fig. 2 is structural representation of the present invention;
Among the figure: 1, housing, 2, seal ring, 3, shield bearing, 4, seal washer.
Embodiment
In order further to understand this high temperature resistant bearing and black box thereof, accompanying drawings is described further.
High temperature resistant bearing and black box thereof, it comprises: housing 1, axle rubber body, shield bearing 3 and seal ring 2, shield bearing 3 is installed between housing 1 and the axle rubber body, housing 1 directly is sealed into one with the axle rubber body, shield bearing 3 tops are provided with seal ring 2, seal ring 2 matches with the external diameter of bearing inner race, the seal washer 4 of present normal structure is removed, seal ring 2 cooperates to realize sealing with the external diameter of bearing inner race, reduce element size and amount of parts, namely reach the effect of refractory seal, reduced again the volume and weight of bearing.
