Abstract
The utility model relates to a bearing, in particular to a bearing with filleted corners on flanges, which is designed by aiming at solving the technical problems that the groove design of the traditional similar bearing is not good enough, so that a steel ball is easy to abrade. The bearing comprises an inner ring, an outer ring, the steel ball, a retainer and a dust cover, wherein the inner ring and the outer ring are respectively provided with a groove and the flange. The bearing has the design point that the surface shape at the part of each groove, which is intersected with the flange, is formed by a filleted corner and a chamfered surface. The bearing has the advantages that the structure and the processing technology are simpler; the frictional contact between the grooves and the steel ball is effectively improved; and the vibration measurement yield of the bearing and the installation yield are improved. The bearing is suitable for serving as the structural improvement of the traditional similar product.
Description
Technical field
The utility model relates to a kind of bearing, is called a kind of bearing of flange belts fillet.
Background technique
National Specification the maximum value and the minimum value of rolling bearing assembling chamfering, but groove curvature and the chamfering and the shape of shelves intersection, limit are stipulated, so each producer does not do requirement to the shape of raceway groove and rib intersection aborning yet.Because the chamfering and the shape of the intersection on raceway groove and rib limit are stipulated, therefore raceway groove often forms wedge angle with the intersection on shelves limit, this wedge angle causes the bearing steel ball of easily damaging when trap is installed steel ball, the vibration measurement of bearings up-to-standard rate is reduced, in a single day such bearing is delivered for use, and bearing installation up-to-standard rate also decreases.Especially more and more higher in the face of the usage requirement of existing bearing, as high-grade rotating speed of motor all in thousand, even very little friction also can cause very big wearing and tearing to bearing.Therefore, it is imperative with the installation up-to-standard rate that improves bearing to improve this class bearing.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model is to provide a kind of bearing that improves the flange belts fillet of vibration measurement of bearings and assembling up-to-standard rate to related domain, and it is not good enough to make it solve existing similar bearing channel design, easily causes the technical problem of steel ball wearing and tearing.The utility model purpose is achieved by the following technical solution.
The bearing of this kind flange belts fillet comprises inner ring, outer ring, steel ball, retainer, dust cover, and inner ring, outer ring are respectively equipped with raceway groove and rib, and its structure outline is that the surface configuration of described raceway groove and rib intersection is made of the corners and fillets face.Substitute original wedge angle by the corners and fillets face, efficiently solve the raceway groove wedge angle easily to the problem of steel ball contact wear.
Described fillet connects rib, and described chamfer surface connects raceway groove.
Described fillet radius is 0.8～1.0mm, and described chamfer surface and described groove curvature tangent direction are 15 ° of angles, and this angular range is a preferred value.
The utility model structure and processing technology are comparatively simple, effectively improve the rubbing contact between raceway groove and the steel ball, have improved vibration measurement of bearings up-to-standard rate and installation up-to-standard rate, are suitable as the architecture advances of existing like product.
Description of drawings
Fig. 1 is a part-structure sectional view of the present utility model, has done A portion among the figure and has confined.
Fig. 2 is an A bilge construction enlarged view among Fig. 1.
Embodiment
Now in conjunction with the accompanying drawings, the utility model is further described.The name of sequence number is called among the figure: inner ring 1, rib 101, raceway groove 102, outer ring 2, steel ball 3, retainer 4, dust cover 5, fillet 6, chamfer surface 7.
As shown in Figure 1, the bearing of this flange belts fillet is to be combined by inner ring, outer ring, steel ball, retainer, dust cover, its processing technology is basic identical with existing known bearing processing, main difference is that inner ring, outer ring are when cutting, the surface configuration of the intersection of raceway groove and rib along 15 ° of chamfer surfaces of groove curvature tangent direction car, form fillet in continuation turning between this 15 ° chamfer surface and rib, fillet radius is controlled at 0.8～1.0mm and gets final product.Use Form tool when that is to say the turning circular arc, Form tool has ground these two lines, and during Vehicle Processing, lathe tool one leans on.
Except that normal inspection, the also close inspection of surface configuration of raceway groove and the intersection on shelves limit is carried out normal heat after the assay was approved and is handled during the laggard factory of Internal and external cycle Vehicle Processing.
This bearing enclose after heat treatment on the basis of former deep groove ball bearing technology each parameter of raceway groove grinding to Internal and external cycle carried out strict control, for bear vibration is met the requirements, except the surface configuration of checking raceway groove and rib intersection, strengthened Internal and external cycle and finish grinded super smart quality control behind the ditch; Trap, cleaning, greasing, gland adopt automatic trap and clean the greasing gland machine automatically, the cleaning of bearing assembly environment, thus guaranteed that bearing reaches the requirement of vibration.
