Abstract

The utility model discloses a novel high-speed deep groove ball bearing holder, wherein annular recesses are respectively formed in the outer side and the inner side of the inner surface of the holder, and wear resistant blocks are embedded in the end face of the outer side of the holder at intervals. The outside diameter of the holder is smaller than a common size. The novel high-speed deep groove ball bearing holder disclosed by the utility model is integrally thin and light, thereby both reducing the cost and reducing the friction between a bearing and an outside diameter blocking edge in the starting process to effectively prolong the service life of the bearing.

Description

Novel high speed deep groove ball bearing retainer

technical field:

The utility model relates to a kind of deep groove ball bearing retainer, particularly relates to a kind of novel high speed deep groove ball bearing retainer.

background technique:

Large high-speed deep groove ball bearing retainer all adopts solid cage, and conventionally by inner ring or outer ring flange, is guided.Retainer conventional structure forms by two, by rivet, connects (referring to Fig. 1).When bearing height turns round, lubricant oil is subject to the effect of centrifugal force, can flow to outer ring, so high speed deep groove ball bearing retainer adopts outer ring flange guiding more, greasy property is better.But large-scale deep groove ball bearing retainer weight ratio is heavier, when bearing shuts down, retainer is fallen on outer ring flange, and when starting, retainer can produce friction with outer ring flange, and this friction often produces fatal impact to bearing, easily causes bearing premature failure.

model utility content:

Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of modern design, lightweight and rub novel high speed deep groove ball bearing retainer little is provided.

The technical solution of the utility model is: a kind of novel high speed deep groove ball bearing retainer, the outside of the internal surface of retainer and inner side arrange respectively annular groove, and on the outside end face of described retainer, interval is inlaid with wear-resistant block.

Described wear-resistant block is bakelite piece.The external diameter of described retainer is less than stock size.

The beneficial effects of the utility model are:

1, the utility model arranges respectively groove in the outside of the internal surface of retainer and inner side and reduces the outside dimension of retainer, retainer integral thinned is lightened, both reduced costs, when reducing again bearing and starting and the friction of external diameter rib, effectively extended bearing working life.

2, the utility model diminishes retainer outside dimension, and inlays bakelite piece at external diameter, can not only make retainer weight saving, has reduced the area of contact of retainer and external diameter rib simultaneously, has reduced friction factor.

3, the utility model is novel in design, lightweight and rub littlely, and it is applied widely, is especially applicable to

High-speed ball bearing, is easy to promotion and implementation, has good economic benefit.

accompanying drawing explanation:

Fig. 1 is the structural representation of retainer in prior art;

Fig. 2 is the structural representation of novel high speed deep groove ball bearing retainer;

Fig. 3 is A-A sectional view in Fig. 2.

embodiment:

Embodiment: referring to Fig. 2 and Fig. 3, in figure, 1-annular groove, 2-wear-resistant block.

A deep groove ball bearing retainer, the outside of the internal surface of its retainer and inner side arrange respectively annular groove 1, and on the outside end face of retainer, interval is inlaid with wear-resistant block 2.Wear-resistant block 2 can adopt bakelite piece, also can adopt other materials.The external diameter of retainer is less than stock size.

The utility model lightens retainer integral thinned, both reduces costs, and when reducing again bearing and starting and the friction of external diameter rib, has effectively extended bearing working life.

The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.

Claims
