Abstract
The utility model relates to a sealed and separated two direction thrust angular contact ball bearing, comprising an outside track (1), an inner track (2), a steel ball (3) and a cage (4); wherein, the inner track is composed of two symmetrical ferrules which have subdivision part and are mutual independent and reciprocating; the two sides of the groove on the inner track are provided with upright rib, and the steel ball is arranged in the groove; two cage with identical structure and size are applied to control the number of the steel ball placing in the two sides; the outer margin of the steel ball is controlled by the outside track body which has two outside rollaway nests; and the two head face of the outside track are respectively provided with an independent seal ring (5). The cage is made of glass fiber enhanced nylon through mould pressing. The structure of the utility model applies the slit seal to depollute the bearing face; and the separated type and the application of fat as lubricant helps increase the type of the bearing and widen the application filed of the bearing.
Description
Technical field
The utility model belongs to technical field of bearings, particularly a kind of sealed type divergence type bidirectional angular contact thrust ball bearing.
Background technique
Existing bidirectional angular contact thrust ball bearing mostly is 2344 and 2347 series, and nominal contact angle is 60 °, is mainly used in supporting precision machine tool main shaft.It is by an outer ring, two inner rings, and a middle spacer ring, two retainers and steel ball are formed.Bearing is detachable, but the element of forming them can not exchange with other identical bearing element, and end face is not with sealing.Preloading by the decision of the spacer ring between last two inner rings of axle of bearing, both usable oils was lubricated for it, also can use grease lubrication, was applicable at a high speed.
Summary of the invention
For solving the existing existing problem of bidirectional angular contact thrust ball bearing, sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model, having solved bidirectional angular contact thrust ball bearing does not have sealing problem, and the new structure of being given birth to makes bidirectional angular contact thrust ball bearing have separable type.
In order to realize the foregoing invention purpose, the utility model has adopted following technological scheme:
Described sealed type divergence type bidirectional angular contact thrust ball bearing is made up of outer ring, inner ring, steel ball, retainer, its inner ring by two symmetries have a subdivision structure and the mutually independent lasso that can exchange constitute, the bear inner ring grooved railway both sides are straight rib, steel ball is housed on raceway groove, and controls the quantity of both sides steel ball by two retainers with same structure and shape respectively; The integral outer ring of two outer raceways of outer cause band of steel ball controls, and two end faces are equipped with separately independently seal ring in the outer ring.
Described sealed type divergence type bidirectional angular contact thrust ball bearing, its retainer material is glass-fiber reinforced nylon, is made by the mold pressing injection moulding.
Owing to adopted technological scheme as mentioned above, the utlity model has following good effect:
1) sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model is a kind of bearing of new structure, overcomes close some shortcomings of serial bearing, has increased the type of bearing, has enlarged the application area of bearing.
2) 72 series of the internal diameter of sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model and outside dimension and angular contact ball bearing, 73 series and standard ball screw bearing internal diameter are consistent with outside dimension, width is the twice of single cover angular contact ball bearing width, not with lock mouthful of its outer ring belongs to outer ring divergence type bearing.
3) nominal contact angle of sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model is 60 °, is the configuration of " O " type after the assembly, can bear bidirectional propulsion thrust load and radial load.
4) retainer is made by glass-fiber reinforced nylon, and it has extraordinary slip and self-lubricating property, can be lower than long time continuous working under 120 ℃ the condition in temperature, and the guidance mode of retainer is the ball guiding.
5) the reconditioning quality size decision that preloads the face that is close to by two relative lassos in the bearing pack timing reconditioning bearing inner race of bearing, bearing assembling back applies with accurate locking nut and preloads.
6) clearance seal is adopted on the bearing two sides, can prevent to pollute, and lubricating system is a grease.
Description of drawings

Among Fig. 1: the 1-outer ring; The 2-inner ring; The 3-steel ball; The 4-retainer; The 5-seal ring.
Embodiment
As shown in Figure 1: sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model is made up of outer ring (1), inner ring (2), steel ball (3), retainer (4), its inner ring (2) by two symmetries have a subdivision structure and the mutually independent lasso that can exchange constitute, inner ring (2) raceway groove both sides are straight rib, steel ball (3) is housed on raceway groove, and controls the quantity of both sides steel ball (3) by two retainers (4) with same structure and shape respectively; The integral outer ring (1) of two outer raceways of outer cause band of steel ball (3) controls, and (1) two end face is equipped with separately independently seal ring (5) in the outer ring.
Sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model, its retainer (4) material is glass-fiber reinforced nylon, is made by the mold pressing injection moulding.
Sealed type divergence type bidirectional angular contact thrust ball bearing of the present utility model, 72 series of its internal diameter and outside dimension and angular contact ball bearing, 73 series and standard ball screw bearing internal diameter are consistent with outside dimension, width is the twice of single cover angular contact ball bearing, not with lock mouthful of its outer ring belongs to outer ring divergence type bearing.The nominal contact angle of bearing is 60 °, is the configuration of " O " type after the assembly, can bear bidirectional propulsion thrust load and radial load.
In addition, retainer of the present utility model is made by glass-fiber reinforced nylon, and as PA66-GF25, it has extraordinary slip and self-lubricating property, can be lower than long time continuous working under 120 ℃ the condition in temperature, and the guidance mode of retainer is the ball guiding.Bearing assembling and after testing after, generally can stamp identical mark with the inner ring of side end face with the outer ring at bearing, purpose is in order to reach best usability, to advise that inner ring does not exchange rigging position at this moment.The reconditioning quality size decision that preloads the face that is close to by two relative lassos in the bearing pack timing reconditioning bearing inner race of bearing, bearing assembling back applies with accurate locking nut and preloads.Clearance seal is adopted on the bearing two sides, can prevent to pollute.Lubricating system is a grease.
On it is used, owing to be the configuration of " O " type after this airframe bearing assembly, be equivalent to (DB) pairing use back-to-back of the single-row angular contact ball bearing of two covers, therefore it can to replace nominal contact angle fully be 60 °, two covers are fitted in together precision ball screw bearing in the mode of (DB) back-to-back, are applied to the supporting of precision machine tool ball screw.According to different applications, the nominal contact angle of bearing can be designed to 40 °, to satisfy different usage requirements.
