Further, radially offered on the inner headed face of inner ring two respectively with two raceways on inner ring periphery
One-to-one dress ball, angle is 90 ° either 120 ° or 150 ° to two dress ball in a circumferential direction, is installed in dress ball
There is plug.
Further, the axially disposed taper pin-hole having for fixing plug on the end face of inner ring, it is equipped with taper pin-hole
There is taper bolt.
Further, the retainer is annular shape, and plurality of pockets, pocket hole have along the circumferential direction been uniformly arranged on retainer
For cylindricality pore structure radially.
Further, it is provided with the end face of inner ring and outer ring for injecting lubricating oil or lubricating grease into raceway
Oil filler point.
Further, some mounting holes have along the circumferential direction been uniformly arranged on the end face of inner ring and outer ring.
Further, the installation portion of column, and the central axis of installation portion and outer ring are provided with the periphery of outer ring
Central axis overlap.
Further, the connecting portion of column, and the central axis and inner ring of connecting portion are provided with the inner headed face of inner ring
Central axis overlap.
Because using above-mentioned technical proposal, the utility model has following superiority：
1st, the inner ring of existing bidirectional angular contact thrust ball bearing is split type two halves structure, inner ring of the present utility model
For monolithic construction, minimize two halves inner ring connecting bolt, the rigid influence of bearing fit relation shaft, pass through reality
Proof is trampled, is rigidly greatly improved using the shafting of the type bearing of integral inner ring structure.
2nd, the inner ring of existing bidirectional angular contact thrust ball bearing be split two halves structure, in order to ensure overall precision and
Rigidity after bearing installation, so bearing bore diameter and fitted shaft must be tight fits during installation, client is extremely difficult when installing；This
The inner ring of utility model is monolithic construction, only needs radial positioning or interference fits during client's hosted mounting design,
Installation difficulty is greatly reduced, improves installation effectiveness.
3rd, the outer ring of existing bidirectional angular contact thrust ball bearing is multilayer steps axle construction, and the effective thickness of raceway is relative
Relatively thin, the structural rigidity of bearing in itself is weaker, and simply the bearing stand under load of small dimension size is typically small, in the use of reality simultaneously
Will not shaft rigidly have a great impact performance, the utility model shoals outer ring Step Shaft constructional depth, is not influenceing axle
Hold and bearing self structure rigidity is effectively improved on the premise of installing and using.
4th, the utility model is by increasing plug（Fill ball）Meet bearing with the method for changing retainer contour structures
Outer ring and the integrally-built design of inner ring, ensure that the stabilization of bearing arrangement overall performance.
5th, the utility model designs oil filler point in outer ring and the end face of inner ring, client is added the maintenance works such as lubricating grease
It is convenient and swift.
