Abstract
The utility model relates to a bearing technology field, the technical scheme of adoption is: a steel ball that angular contact ball bearing assembles between bearing inner race and bearing inner race including bearing inner race, bearing inner race and through the holder be equipped with the pocket hole on the holder, the downthehole steel ball that is equipped with of pocket, at pocket hole axial one side opening, the opening part is equipped with the locking face that encloses into the fore shaft, the locking face include vertical plane section, joint face section and the level end face section that from interior to exterior arranged in proper order, vertical plane section and level end face section are connected through the joint face section. The utility model has the advantages of for, the holder fore shaft is rational in infrastructure, and the fore shaft size is controlled more easily, long service life, the improvement holder pulls out the power of taking off to the locking force and the improvement holder of steel ball.
Description
Technical field
This utility model relates to technical field of bearings, specifically a kind of angular contact ball bearing.
Background technology
As shown in Figure 1, the fore shaft of the retainer used on existing angular contact ball bearing is mutually about 120 degree inclined-planes by two and forms, physical dimension is difficult to detect control, bearing is in the case of having vibration or stress relatively big, if retainer fore shaft size is excessive, retainer lock ball power can be smaller, deviates from when causing steel ball stress bigger from retainer, and retainer rolls thus causes bearing initial failure.
It addition, existing angular contact ball bearing upper belt pulley is fixing through jump ring assembling, this structure is relatively low due to bearing load carrying capacity, and the life-span is the shortest.
Summary of the invention
The present utility model purpose: for the defect overcoming prior art to exist, this utility model provides a kind of retainer locking notch structure reasonable, fore shaft size is easier to control, service life length angular contact ball bearing, improve retainer and to the coupling mechanism force of steel ball and improve retainer pull-out force.
For achieving the above object, this utility model provides following technical scheme: a kind of angular contact ball bearing, include bearing outer ring, bearing inner race and be assemblied in the steel ball between bearing inner race and bearing outer ring through retainer, described retainer is provided with pocket hole, pocket is equipped with steel ball in hole, an axial side opening in pocket hole, opening part is provided with the locking face surrounding fore shaft, it is characterized in that: described locking face includes that perpendicular section, interface section and the horizontal end face section being sequentially arranged from the inside to the outside, described perpendicular section and horizontal end face section connect through interface section.
By using technique scheme, the locking face surrounding fore shaft uses syllogic design, and fore shaft size is easier to control, and increases fore shaft power, steel ball not readily disengages from out, it is greatly improved bearing rotating speed, increases steel ball self-lock ability, increase fore shaft intensity, reduce axial float, thus be not easy to come off by retainer after axial force, improve retainer pull-out force, extend bearing service life.
Preferably, described interface section is circular shape.Under the design of this structure, interface is rational in infrastructure, easy to process and intensity good.
Preferably, the outer circumference surface of described bearing outer ring is provided with and coordinates, for conveyer belt, the dentalation being in transmission connection.Under the design of this structure, being directly processed to form the dentalation coordinated for conveyer belt on bearing outer ring, belt pulley that will be traditional is one-body molded on bearing outer ring, reduce spare and accessory parts, compact conformation, reduce cost, reduce rigging error, increase bearing capacity, improve bearing life.
Below in conjunction with the accompanying drawings this utility model is further described.
Accompanying drawing explanation
Fig. 1 is structural representation at retainer fore shaft of the prior art；
Fig. 2 is the structural representation of this utility model specific embodiment angular contact ball bearing；
Fig. 3 is structural representation at this utility model specific embodiment retainer fore shaft.
Detailed description of the invention
See accompanying drawing 2 and accompanying drawing 3, a kind of angular contact ball bearing disclosed in this utility model, include bearing outer ring 1, bearing inner race 2, and it is assemblied in the steel ball 4 between bearing inner race 2 and bearing outer ring 1 through retainer 3, described retainer 3 is provided with pocket hole 31, steel ball 4 it is equipped with in pocket hole 31, an axial side opening in pocket hole 31, opening part is provided with the locking face 312 surrounding fore shaft 311, described locking face 312 includes the perpendicular section 3121 being sequentially arranged from the inside to the outside, interface section 3122 and horizontal end face section 3123, described perpendicular section 3121 and horizontal end face section 3123 connect through interface section 3122.Wherein preferred, described interface section 3122 is circular shape.Certainly as deformation program of the present utility model, interface section can also use the inclined design of inclination, but uses circular shape design, processes more convenient, and intensity is more preferable.
Angular contact ball bearing of the present utility model, the locking face surrounding fore shaft uses syllogic design, and fore shaft size is easier to control, and increases fore shaft power, steel ball not readily disengages from out, it is greatly improved bearing rotating speed, increases steel ball self-lock ability, increase fore shaft intensity, reduce axial float, thus be not easy to come off by retainer after axial force, improve retainer pull-out force, extend bearing service life.
It addition, the outer circumference surface of described bearing outer ring 1 is provided with coordinates, for conveyer belt, the dentalation 11 being in transmission connection.Bearing outer ring is directly processed to form the dentalation of the power transmission coordinated for conveyer belt, takes turns with conventional belt compared with being assemblied on bearing outer ring through jump ring, reduce spare and accessory parts, compact conformation, reduces cost, reduces rigging error, increase bearing capacity, improve bearing life.
