Abstract

A multi-collar linkage middle and high speed durable bearing which comprises an outer ring (1), one or more middle rings (3) and an inner ring (7) from the outside in, wherein an outer collar retainer (5) is arranged between the outer ring and the middle rings; rolling bodies are arranged on the retainer; middle collar retainers are arranged between the middle rings; rolling bodies are arranged on the retainers; an inner collar retainer (6) is arranged between the middle rings and the inner ring; and rolling bodies are arranged on the retainer. According to the bearing, high-speed friction of each collar, and noise can be reduced, and the service life of the bearing is prolonged. The security assurance is improved, and the service cost and maintenance cost are lowered.

Description

The durable bearing of many ring interlock high speeds

Technical field

The present invention relates to a kind of bearing, is a kind of many collar bearings specifically.

Background technique

The rolling element of general bearing is all to turn round on the retainer between inside and outside two circles, and rotating speed is higher, temperature arrising caused by friction is higher, directly affects bearing working life, has increased and has changed and maintenance number of times, has affected greatly working efficiency, has fault occurred frequently and potential safety hazard.

Summary of the invention

The object of the present invention is to provide the durable bearing of a kind of many ring interlock high speeds, its rolling element is more than two circles, when needs high speed turns round, makes total rotational speed be assigned to respectively each circle,

Reduced and respectively enclosed unit speed, reduced unit high-speed friction degree, reduced noise, improved bearing working life, obtained the unapproachable high rotating speed of plain bearing.

Technological scheme of the present invention is as follows:

The durable bearing of ring interlock high speed, it for outer ring, centre circle, inner ring form, establishes outer shroud retainer by outside to inside between outer ring and centre circle, has rolling element on this; Between centre circle and inner ring, establish interior ring retainer, on this, have rolling element.

The durable bearing of ring interlock high speed, it for outer ring, above centre circle, an inner ring form, establishes outer shroud retainer by outside to inside between outer ring and centre circle, has rolling element on this; Between centre circle and centre circle, establish middle ring retainer, on this, have rolling element; Between centre circle and inner ring, establish interior ring retainer, on this, have rolling element.

Above-mentioned retainer upper and lower surface is all equipped with rolling element.

Above-mentioned rolling element is ball.

The invention has the advantages that: 1, this device reduces every ring high-speed friction, reduce noise, improve bearing working life.2, increase safety guarantee, and reduce user cost and maintenance cost.3, the retainer of biserial is to dress, and rolling element degree of stability is high, allows close together between rolling element, can fill rolling element more, under the identical condition of rotating speed, increases whole load-carrying ability.

Fig. 2 is the single-row structure plan view of the embodiment of the present invention;

Fig. 3 is embodiment of the present invention double column structure generalized section;

Fig. 4 is embodiment of the present invention biserial outer shroud retainer plan view;

A in Fig. 5 Fig. 4 is to view.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

By Fig. 1-2, can be seen the single-row structure of this device, it for outer ring 1, centre circle 3, inner ring 7 form, establishes outer shroud retainer 5 by outside to inside between outer ring and centre circle, has ball 4 on this; Between centre circle and inner ring, establish interior ring retainer 6, on this, have ball 4.

By Fig. 3-5, can be seen the double column structure of this device, between above-mentioned outer ring and centre circle, 5 two of set outer shroud retainers, to dress, are provided with biserial ball 4; Between centre circle and inner ring set interior ring retainer 6 be also two to dress, be provided with biserial ball 4.The 8th, biserial ball retainer divides apart from nest; Retainer can be with having the synthetic light material manufacture of anticorrosion antiwear, and two back-to-back biserial ball centres that are clipped in have the effect of good maintenance spacing, easy for installation, reliable performance.

The design is a kind of acquisition under the prerequisite of required rotating speed, can design the above ball retainer of two circles from inside to outside, in every circle retainer, be provided with ball, its performance seems and is: bearing housing bearing, only centre circle plays dual role, is the outer ring of interior ring retainer ring rail and the inner lane of outer shroud retainer.Design gets up to obtain to be no less than at bearing operation total rotating speed that two circle balls are added up mutually and allowed like this, when needs high speed turns round, make total rotational speed be assigned to respectively each circle, reduced and respectively enclosed unit speed, reduce unit high-speed friction degree, reduce noise, improve bearing working life, obtain the unapproachable high rotating speed of plain bearing.This device can be designed to the single-row and double row bearing of high speed.

Bearing assemble on axle and on bearing support in the running, interior, in, outer ring ball variable speed rotating in same direction simultaneously, according to the requirement of rotating speed load, can make in design the interlock of bearing multi-turn and widen or thicken in encircle retainer or to filling.
