Abstract

A corner contact ball bearing belonging to a rolling bearing technical field includes an internal ring, an external ring, a rolling body which is arranged between the internal and external ring by a retaining frame, and a pair of sealing rings which are arranged at two ends of the internal and external rings; the external round surface of the internal ring and the internal round surface of the external ring are respectively concavely provided with a raceway which is arranged for the rolling of the rolling body; the utility model is characterized in that retaining edges at two sides of the raceway of the internal ring are designed as sidesteps. As the retaining edges at two sides of the raceway of the internal ring are designed as sidesteps by the utility model, therefore, no matter on the condition of positive installation or reverse condition, when released, the disassembly force imposed on the bearing can be born by a pair of sidesteps which has the function of retaining shoulder, in this way, the bearing can not disperse, thus the service life of the bearing is prolonged; meanwhile, the utility model has the advantages of simple structure, convenient disassembly and assembly, etc.

Description

Angular contact ball bearing
Technical field
The utility model relates to a kind of angular contact ball bearing, is to the improvement of the angular contact ball bearing structure on the existing wireline reel that particularly is applied to the high speed winding head on the chemical fibre spinning equipment, belongs to technical field of rolling bearings.
Background technique
Angular contact ball bearing on the wireline reel of the wrapping head of existing chemical fibre spinning equipment, its structure as shown in Figure 1, the a pair of seal ring 5 that it comprises inner ring 2, outer ring 1, is arranged at the rolling element 3 between the inside and outside circle 2,1 and is located at inside and outside circle 2,1 two ends by retainer 4, be concaved with the raceway 7,6 that rolls for rolling element 3 on the inner headed face of the periphery of described inner ring 2 and outer ring 1 respectively, one side rib of the raceway 7 of described inner ring 2 is designed to step 8, and opposite side one side of inner ring stress surface (promptly away from) rib is designed to slope 9.The angular contact ball bearing on this band slope 9, there is following defective in actual use: at first, when mounted, because because of carelessness and usually bearing can take place is mounted anti-situation, in case bearing is mounted instead, so when taking off bearing, need to unload bearing from wireline reel in axial reinforcing, like this, one side on the band slope 9 of inner ring 2 is not owing to there is to be provided with the step of shoulder block effect, thereby be easy to the split sequence of sanqu songs within a particular musical mode at the effect lower bearing of removal force, bearing is not also used just damaged; In addition, when bearing working needs maintaining after a period of time, also need to unload lower bearing, therefore, equally situation recited above can take place.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, mounting or dismounting are convenient, no matter positive and negative dress all can guarantee bearing can the split sequence of sanqu songs within a particular musical mode when unloading, be beneficial to the angular contact ball bearing that improves working life.
The purpose of this utility model is achieved like this, a kind of angular contact ball bearing, the a pair of seal ring 5 that comprises inner ring 2, outer ring 1, is arranged at the rolling element 3 between the inside and outside circle 2,1 and is located at inside and outside circle 2,1 two ends by retainer 4, be concaved with the raceway 7,6 that rolls for rolling element 3 on the inner headed face of the periphery of described inner ring 2 and outer ring 1 respectively, be characterized in: two side ribs of the raceway 7 of described inner ring 2 all be designed to step 8,8 '.
Step 8,8 ' symmetrically described in the utility model is distributed in the both sides of raceway 7.
Rolling element 3 described in the utility model is any one of steel ball or ceramic ball.
The utility model since with two side ribs of the raceway 7 of inner ring 2 all be designed to step 8,8 ', no matter thereby be under the situation of formal dress or anti-dress, when unloading, the suffered removal force of bearing can be by a pair of step 8,8 that plays the shoulder block effect ' bear, make the bearing can the sequence of sanqu songs within a particular musical mode like this, thereby can prolong the working life of bearing; Simultaneously, also have advantages such as simple in structure, that mounting or dismounting are convenient.
Description of drawings
Fig. 1 is the structure diagram of prior art of the present utility model.
Fig. 2 is a structure diagram of the present utility model.
Among the figure: 1. the outer ring, 2. inner ring, 3. rolling element, 4. retainer, 5. seal ring, 6. raceway, 7. raceway, 8. step, 8 '. step, 9. slope.
Embodiment
By following description to embodiment, will help to understand the utility model more, still, specific embodiment can't be considered as restriction to some extent to technical solutions of the utility model.
See also Fig. 2, Fig. 2 is the most common angular contact ball bearing that is applied on the wireline reel of wrapping head of chemical fibre spinning equipment, it mainly comprises inner ring 2, outer ring 1, rolling element 3, retainer 4 and a pair of seal ring 5, roller 3 can be the steel ball, it also can be the ceramic ball of making by silicon nitride material, rolling element 3 has one group, between cloth on retainer 4, in retainer 4 is placed in together with one group of rolling element 3 on it, outer ring 2, between 1, and one group of rolling element 3 is positioned at, outer ring 2,1 raceway 7, in 6, raceway 7,6 are respectively formed on the inner headed face of the periphery of inner ring 2 and outer ring 1, its sectional shape is an arc, its size should be complementary with the excircle dimension of rolling element 3, inner ring 2 rotates with respect to outer ring 1 by rolling element 3, retainer 4 plays isolation, divide equally rolling element 3 and prevent collision, reduce friction and improve effects such as lubricated, the rib of raceway 7 two sides all is designed to step 8,8 ', step 8,8 ' when unloading lower bearing, work to bear removal force, can guarantee that like this bearing can the sequence of sanqu songs within a particular musical mode, improve the working life of bearing.In addition, a pair of seal ring 5 of the present utility model is installed in the two ends of inside and outside circle 2,1, can prevent foreign or dust intrusion bearing inside, can also stop lubricating grease outwards to overflow simultaneously, guarantees that bearing has higher running speed.
The utility model is when assembling, and retainer 4 and one group of rolling element 3 can not be packed into from the slope 9 of Fig. 1 (for prior art) again, but adopts lasso mode eccentric and folder distortion outer ring to come running in bearings.
In the bearing working process, inner ring 2 drives rolling element 3 and retainer 4 rotates around bearing axis together, rolling element 3 had not only revolved round the sun but also rotation in the high speed rotating process of bearing, keep motionless relatively between outer ring 1 and a pair of seal ring 5, a pair of seal ring 5 remains minimum gap with inner ring 2 in the bearing rotary course, to guarantee both to have kept good sealing effect with inner ring 2, it is excessive to be unlikely to friction to occur again, produces superheating phenomenon.
