Abstract

The utility model relates to an outer ring guide V-shaped stamping holder bearing which comprises an outer ring, an inner ring, rolling bodies, and a holder, wherein both ends of the holder of the bearing are guided by the edge blocking path of the outer ring; a bag hole of the holder can be in the shape of a rectangle, a square, a waist drum, or an oval; convex beams of the holder respectively form a V shape; the rolling bodies are positioned in the bag hole of the holder, and the rolling bodies are assembled with the vertexes of the two convex beam of the holder to form a locking point. The utility model has the advantages of easy processing, raw material saving and a plurality of rolling bodies. In addition, the service life of the bearing is prolonged.

Description

Outer ring guide V-type stamping holder bearing

The utility model is the parts that belong in the common engineering machinery.

Be used for the single-row first post roller bearing of common engineering machinery, by inside and outside circle, rolling element, retainer is formed.Wherein the brass entity is the processing of car system, and rivet connects, and manufacturing efficiency is low, the product cost height; B-mode, the L type structure retainer of punching press commonly used, because due to the structure, manufacturability is relatively poor, and centering property and lock rolling element lock dot structure poor reliability, retainer noise height during rotation.

The purpose of this utility model is a kind of outer ring guiding of design V-type pressing cage bearing, owing to adopt the outer ring guiding, retainer is a v-shaped structure, and its simplified manufacturing technique improves structural reliability and economic benefit.

Of the present utility modelly mainly form, as shown in Figure 1 by outer ring 1, retainer 2, rolling element 3 and inner ring 4.This bearing is to adopt the outer ring guiding, and the protruding beam of retainer is a v-shaped structure.It is characterized in that: retainer 2 two ends are directly guided by the rib of outer ring 1; The pocket hole of retainer 2 can be rectangle, square, dolioform, oval, and the protruding beam of its retainer is the V-arrangement shape; Rolling element 3 places the pocket hole of retainer 2, forms the lock point with the summit of two protruding beams of V-arrangement of retainer, makes the lock point cross rolling element 3 maximum diameters, reaches the purpose of pinning rolling element 3; Shown in Fig. 3,5.The external diameter of retainer 2 and outer ring 1 rib are the gap guiding, as shown in Figure 1, can realize the outer ring guiding; Make compact structure like this, can adorn rolling element 3 more; Outer ring guiding rotation, centering property is good, and noise is low, and the rolling element exposed surface is big, is convenient to lubricate, and improves bearing life.

V-type retainer lock dot structure principle, show as Fig. 4: in a circle, angle theta, radius R, r are certain, and the pairing chord length of R, r is also certain.The chord length J of long radius R correspondence _R, the pairing chord length Jr of minor radius r sets up.

V-type retainer outer diameter D c=2R, the protruding beam circumcircle of retainer dc '=2r shows as Fig. 3.The rolling element that is lockable is between J _RAnd between the Jr, show as Fig. 5.

Rolling element diameter Dwe＜J _R, be convenient to put into rolling element, Dwe＞Jr is convenient to pin rolling element, and rolling element can not drop out from the Jr size, has guaranteed lock rolling element reliability.

Advantage that the utility model has compared with the prior art and effect:

V-structure retainer and brass entity and B-mode retainer ratio can be adorned the rolling element number more, improve bearing life 24%, and in conjunction with reinforced transformation, bearing life can be higher.

Save the brass metallic material, can reduce the retainer cost of production, on average reduce by 8～10 times.Reduce Production of bearing cost about 40%.

Reduce to produce man-hour: with brass solid cage ratio, when reducing worker about 80%; During the rigger about 30%.With B-mode retainer ratio, reduce about 70%.

With brass solid cage ratio, reduce die cost about 30%.

Embodiment of the present utility model:

The utility model mainly is made up of outer ring 1, retainer 2, rolling element 3, inner ring 4; Wherein inside and outside circle, rolling element is for selecting part for use; Through the blank moulding, bending towards the pocket hole, is radially given in car limit and cutting at the end after the shaping to retainer with sheet metal.

Retainer 2 is put into outer ring 1, and rolling element 3 is loaded in the pocket hole of retainer 2, and is crooked again along the axial reinforcing of the both ends of the surface of retainer 2 with mold, and inner ring 4 is introduced in the interior fourth contact of rolling element 3, forms outer ring guiding V-type pressing cage bearing.
