Abstract
The utility model discloses a novel angular contact ball bearing retainer, which belongs to the technical field of angular contact ball bearing retainers. The novel angular contact ball bearing retainer has a semi-enclosed structure; oil lines are formed on the surfaces of pockets of the retainer; pocket reinforcing claws are arranged in the pockets; and a stress release groove is formed between the two pockets on the retainer. According to installation test, compared with the conventional nylon retainer, the novel angular contact ball bearing retainer has the advantages: the bearing rotating speed is increased by 30 percent, the noise is reduced by 35 percent, the cost is reduced by 20 percent, the weight is reduced by 15 percent, and the service life is prolonged by 10 percent.
Description
Technical field
The utility model relates to a kind of novel angular contact ball bearing cage, belongs to the angular contact ball bearing cage technical field.
Background technique
The angular contact ball bearing limit speed is higher, can bear radial load and thrust load simultaneously, also can bear pure thrust load, and its thrust load ability is determined by wrapping angle, and increases with the increase of wrapping angle.Contact angle is generally: several types such as 15 °, 25 °, 40 °.Common structure is that Internal and external cycle is inseparable, and the fore shaft design of steel ball is in the outer ring.This class bearing is widely used in high rotating speed machine spindle such as machine tool chief axis, high frequency motors, gas turbine, centrifugal separator, compact car front-wheel, differential pinion-shaft.In recent years, along with the rapid development of mechanical field equipment performance, require this class bearing to have higher limit speed.At present, though angular contact ball bearing generally adopts traditional nylon cages alternative metals retainer to satisfy this demand, retainer receives the restriction of conventional construction, and rotating speed promotes amplitude and not obvious.
Summary of the invention
Defective in view of the prior art existence; It is lighter that the purpose of the utility model provides the traditional retainer of a kind of weight ratio, has higher rotating speed, more high mechanical properties, lower vibration, good wear resistance and the novel angular contact ball bearing cage of self-lubricating property.
For realizing above-mentioned purpose; The technical solution that the utility model adopted is: a kind of novel angular contact ball bearing cage, be semi-closed structure, and at retainer pocket hole surface oily line is set; The pocket hole is set in the pocket hole strengthens pawl, between two pocket holes stress relief grooves is set on the retainer.
The diameter of pawl aperture less than steel ball strengthened in said pocket hole.
The assembly process of said novel angular contact ball bearing is following: earlier with the inner ring horizontal positioned; Retainer is sleeved on the inner ring, steel ball is evenly packed in the retainer pocket hole again, the hold depth that steel ball relies on retainer pocket hole to strengthen pawl is fixed steel ball; At last; Outer ring level cover is pressed on the inner assembly that inner ring, steel ball and retainer assemble, relies on fore shaft and the inner assembly of outer ring to be integrally formed, the assembling of completion bearing.
The beneficial effect of the utility model: semi-closed structure is adopted in retainer pocket hole, reduces area of contact, alleviates retainer weight; Increase oily line at retainer pocket hole surface, guarantee that steel ball obtains sufficient lubrication when work, reduce pivot friction, improved bearing running accuracy and rotating speed, reduced Rotation Noise; Optimize the containing coefficient in steel ball and pocket hole, reduced the vibrating noise of steel ball; Increase the retainer stress relief grooves, avoid stress to concentrate, effectively guarantee retainer circularity, avoided the unbalance stress phenomenon of steel ball running; Warp is installed and is tested contrast, compares with traditional nylon cages, and bearing rotating speed raising 30%, noise reduction by 35%, cost reduction by 20%, weight reduction by 15%, life-span increase by 10%.
Description of drawings
Fig. 1 is a kind of novel angular contact ball bearing assembly structure schematic representation;
Fig. 2 is a kind of novel angular contact ball bearing cage overall structure schematic representation;
Fig. 3 is a retainer pocket hole A-A sectional view among Fig. 2.
Among the figure: 1, inner ring, 2, retainer, 3, the outer ring, 4, steel ball, 5, oily line, 6, stress relief grooves, 7, the pocket hole strengthens pawl.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
Like Fig. 2, a kind of novel angular contact ball bearing cage shown in 3, be semi-closed structure, at retainer pocket hole surface oily line 5 is set, the pocket hole is set in the pocket hole strengthens pawl 7, between two pocket holes stress relief grooves 6 is set on the retainer.
The diameter of pawl 7 apertures less than steel ball 4 strengthened in said pocket hole.
The assembly process of novel angular contact ball bearing as shown in Figure 1 is following: earlier with inner ring 1 horizontal positioned; Retainer 2 is sleeved on the inner ring 1, steel ball 4 is evenly packed in the retainer 2 pocket holes again, it is fixing with steel ball 4 that steel ball 4 relies on retainers 2 pocket holes to strengthen the hold depth of pawls 7; At last; Outer ring 3 level covers are pressed on the inner assembly that inner ring 1, steel ball 4 and retainer 2 assemble, rely on fore shaft and the inner assembly of outer ring 3 to be integrally formed, the assembling of completion bearing.
