The inwall end of the outer ring offers the first seal groove, and the outer wall end of inner ring offers the second seal groove, and described first is close
Sealing ring is embedded between sealing groove and the second seal groove, leakproof alicyclic ring between sealing ring and ball, is provided with, leakproof alicyclic ring is near ball
Side be arc convex, the outer ring includes the heat resistant and wear resistant layer and the enhancement layer of outer layer of internal layer, heat resistant and wear resistant layer by
Primary crystal Si and Mg2The hybrid particles of Si are made.
The sealing ring is arranged between outer ring and inner ring and positioned at the top and bottom of annular chamber.
The leakproof alicyclic ring is arranged on the inner surface of outer ring.
The heat resistant and wear resistant layer and enhancement layer are layered molding by centrifugal casting.
The enhancement layer is made up of high-temperature-resistant steel.
Compared with the prior art, beneficial effects of the present invention are as follows：
The high rotating speed leakproof fat bearing of high temperature resistant of the present invention, good seal performance can effectively prevent the dust in air from entering
Enter Bearing inner, while prevent the leakage of bearing oils and fatss when running up, produce bearing removing oil and premature failure；And have
There are stronger wear resistance at elevated temperature and non-deformability, can run well in ambient temperature height, rotating speed compared with the case of；This
Invention can preferably prevent the leakage of grease by leakproof alicyclic ring is provided between sealing ring and ball, meanwhile, leakproof fat
Ring can bear the pressure effect of grease in bearer ring die cavity, it is to avoid grease is acted on to the direct pressure of sealing ring, from
And eliminate the grease leakage phenomenon for sealed ring deformation being made and being caused due to the pressure effect of grease；The leakproof alicyclic ring is leaned on
The side of nearly ball is arc convex, and arc convex increases the contact area with grease, and having further functioned as prevents lubrication
Fat is revealed from sealing ring；The outer ring adopts the enhancing Rotating fields of heat resistant and wear resistant layer and outer layer, and is layered by centrifugal casting
Molding, with preferable binding ability, the hybrid particles density of primary crystal Si and Mg2Si is less than high-temperature-resistant steel, centrifugal casting
Cheng Zhongxiang centers are gathered, and form heat resistant and wear resistant layer, and combine with outer steel infiltration, using the high intensity of steel, reach steady
The purpose of fixed structure, at the same can high temperature resistant wear-resistant, there is stronger wear resistance at elevated temperature and resistance after making bearing assembling
Shape ability, in the case of operating ambient temperature height, rotating speed height can remain normal and runs, solve bearing in high-speed and high-temperature
In the case of rotation, the abrasion of itself is reduced, so as to increase the service life.
