Abstract

The invention relates to a bearing retainer, which comprises two identical edge retaining rings and pillars. The pillars connecting the two edge retaining rings to form a stand column structure. The retainer is placed between a bearing outer ring and an inner ring. The pillars and the edge retaining rings are all made of a steel material. Bearing rollers able to rotate freely are clamped between two adjacent pillars. An inward concave curved surface fitting the bearing rollers is formed on one pillar side facing the bearing rollers. The retainer is made of the steel material, so that the strength and hardness of the retainer can be effectively improved, and its service life can be prolonged. Also, a wear resistant layer is coated on the curved surfaces of the pillars, thus prolonging the service life of the pillars.

Description

Retainer
Technical field
The present invention relates to a kind of retainer.
Background technique
The effect of retainer in bearing mainly contains:
1, guiding and drive rolling element roll at correct raceway;
2, retainer is equally spaced with rolling element, is distributed on raceway and gets on the circumference when preventing work and run foul of each other and rub between rolling element;
3, in the divergence type bearing, rolling element and a collar combination are in the same place, come off to prevent rolling element.
So the intensity of retainer and stability directly have influence on quality and the working life of bearing, retainer links together the both sides back-up ring by pillar and forms column-type, connect the die cross section of usefulness take the front strut two ends as circular, it is cylindrical that die becomes, although this can play the effect of connection, along with bearing vibration and retainer at work rotates, because the effect of centrifugal force, retainer is loose or distortion easily, the situation such as cause that bearing is scrapped;
Retainer generally has nylon cages and brass retainer, the sliding capability that nylon cages has is lightweight, elasticity is strong, good and good marginal greasy property, but its running temperature is lower, running temperature needs less than 120 ℃, the brass retainer has high, the higher shockproof anti-acceleration performance of intensity and is fit to the ultra high speed running relevant with circulating oil lubrication, and is high but its price is but wanted relatively.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of retainer is provided, solve the low and not wear-resisting situation of traditional bearing retainer intensity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of retainer, comprise two identical side bumper circle and pillars, pillar connects the both sides back-up ring and forms column structure, described retainer is positioned between bearing outer ring and the inner ring, described pillar and side bumper circle all adopt steel material to make, hold bearing roller free to rotate between adjacent two pillars, pillar is formed with the curved surface with the suitable indent of bearing roller on the one side of bearing roller.
Furtherly, be coated with wearing layer on the described curved surface.
Furtherly, described pillar two ends is ellipsoidal structure.
The invention has the beneficial effects as follows: the invention provides a kind of retainer, retainer adopts steel material to make, and intensity and hardness that can the Effective Raise retainer prolong its working life; And be coated with coating rubbing-layer at the curved surface of pillar, prolong equally the working life of pillar.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 be among Fig. 1 A-A to sectional drawing.
Fig. 3 is the partial enlarged drawing at B place among Fig. 2.
Wherein: 1, side bumper circle, 2, pillar, 2-1, wearing layer.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of retainer shown in Figure 3 such as Fig. 1 Fig. 2, comprise two identical side bumper circles 1 and pillar 2, pillar 2 connects both sides back-up ring 1 and forms column structure, retainer is positioned between bearing outer ring and the inner ring, pillar 2 and side bumper circle 1 all adopt steel material to make, hold bearing roller free to rotate between adjacent two pillars 2, pillar 2 is formed with the curved surface with the suitable indent of bearing roller on the one side of bearing roller, be coated with wearing layer 2-1 on the curved surface, pillar 2 two ends are ellipsoidal structure.
Retainer adopts steel material to make, and intensity and hardness that can the Effective Raise retainer prolong its working life; And be coated with coating rubbing-layer 2-1 at the curved surface of pillar 2, and prolonging equally the working life of pillar 2, the end face of pillar 2 is oval, the attachment post of this ellipsoidal structure can make pillar 2 and side bumper circle 1 structure more stable.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.

Claims (3)
