Description
Technical field
The utility model belongs to technical field of bearings, more particularly, to a kind of new thrust bearing.
Background technology
At present, thrust bearing is generally thrust ball bearing and thrust roller bearing.Thrust ball bearing is using when running at high speed
The design of thrust load can be born, general carrying specific thrust roller bearing is small and can not bear radial load；Thrust roller bearing
For bearing axle based on axial load, united load, but radial load must not exceed the 55% of axial load.Therefore,
It is necessary to be improved.
The content of the invention
The purpose of this utility model be for above-mentioned prior art exist it is not enough there is provided a kind of new thrust bearing, it
The characteristics of with big load axially and radially and bearing capacity axially and radially and good airproof performance can be carried.
To achieve these goals, the technical scheme that the utility model is used is：A kind of new thrust bearing, including it is upper
The steel ball and retainer of the numbers such as piece, bottom sheet, multiple taper rollers and taper roller,
It is described upper piece and bottom sheet on be provided with the circular cone roller surface and and steel ball for matching and cooperating with taper roller
The arcuate groove face of matching, steel ball contacts to form contact angle r with arcuate groove face；
The tapered pocket hole matched with taper roller and the circular pocket matched with steel ball are arranged at intervals with described retainer
Ring packing boss is additionally provided with hole, the two sides of described retainer；
It is described upper piece and bottom sheet on be additionally provided with the annular groove coordinated with ring packing boss；
Described taper roller and steel ball by retainer keep being placed in upper piece between bottom sheet, taper roller can be along circular cone
Roller surface is rolled, and steel ball arcuately roller surface can be rolled, and ring packing boss cooperatively forms sealed end with annular groove.
Described taper roller and the quantity of steel ball are odd number.
The length of described circular cone roller surface be more than arcuate groove face, and circular cone roller surface two ends arcuate groove face it
Outside.
After said structure, the utility model is compared to the prior art advantageously：Knot of the present utility model
Structure is simple, the structure combined using taper roller with steel ball, and steel ball forms angular contact with arcuate groove face, therefore, can
Carry load axially and radially and bearing capacity axially and radially is all big；Ring packing boss cooperatively forms close with annular groove
End-blocking, makes its good airproof performance, can extend the service life of bearing.

It is described upper piece 1 and bottom sheet 2 on be provided with the circular cone roller surface 6 that matches and cooperate with taper roller 3 and with
The arcuate groove face 7 that steel ball 4 is matched, steel ball 4 contacts to form contact angle r with arcuate groove face 7.
The tapered pocket hole 8 matched with taper roller 3 and the circle matched with steel ball 4 are arranged at intervals with described retainer 5
Ring packing boss 10 is additionally provided with shape pocket hole 9, the two sides of described retainer 5.
It is described upper piece 1 and bottom sheet 2 on be additionally provided with the annular groove 11 coordinated with ring packing boss 10.
Described taper roller 3 and steel ball 4 keep being placed in upper piece between 1 and bottom sheet 2 by retainer 5, and taper roller 3 can
Rolled along circular cone roller surface 6, steel ball 4 arcuately roller surface 7 can be rolled, and ring packing boss 10 is cooperatively formed with annular groove 11
Sealed end.
It is preferred that, described taper roller 3 and the quantity of steel ball 4 are several numbers.
It is preferred that, the length of described circular cone roller surface 6 is more than arcuate groove face 7, and circular cone roller surface 6 two ends in arc
Outside shape roller surface 7, the normal rolling of taper roller 3 so can guarantee that.
