Abstract

The invention provides a low-friction retainer of a super-huge type bearing, which comprises a retainer body, wherein the retainer body is ring-shaped, a pocket for installing a running pulley is arranged on the retainer body, drainage slots are arranged on the upper end face and the lower end face of the retainer body and the end face of the inner circumferential face, the drainage slots are arranged on each end face of the retainer body at intervals, a gap exists between the tops of every two adjoining drainage slots, guide slots are symmetrically arranged on two inclined faces of V-shaped slots, and the directions of the guide slots are extended from the bottom of the drainage slots to the top of the drainage slots. The guide slots are symmetrically arranged on the two opposite inclined faces of the drainage slots, lubricating oil in a bearing heavy-load industrial mine evenly flows along the guide slots on the two inclined faces through the bottom of the slots, and the running stability of the bearing is kept according to the ordered flow of the lubricating oil, so that the instability of the disordered motion of the lubricating oil can be greatly reduced when the lubricating oil is guided, and the damping effect of bearings can be improved.

Description

A kind of low friction retainer of extra large size bearing

Technical field

The present invention relates to a kind of extra large size bearing, specifically a kind of low friction retainer of extra large size bearing.

Background technique

At present, in field of bearings, for guaranteeing running accuracy and the working life of bearing, all requiring each end face of retainer is smooth surface, lubricant oil is infused between retainer and bearing enclose for lubricated, yet extra large size bearing is not in use like this, due to this class bearing in use need to bear larger axially, radial load and tilting moment, load is carried on retainer greatly, be easy to make the damage of retainer, reduced the working life of extra large size bearing, on the end face that some enterprises contact with bearing enclose at retainer through research and development, hook groove is set, in groove, form oil film so that retainer and Internal and external cycle are separated, this kind of structure effect on lubricating is better, thereby yet in heavy duty running, exist during lubricating oil flow in due to hook groove very large unstability very easily to occur vibrations in causing such bearing operation, greatly reduce antiwhip.

Summary of the invention

The object of the invention is the deficiency for solving the problems of the technologies described above, a kind of low friction retainer of extra large size bearing is provided, it is simple in structure, while being used in conjunction with extra large size bearing, has greatly reduced vibration, improves antiwhip.

The present invention is the deficiency solving the problems of the technologies described above, the technological scheme adopting is: a kind of low friction retainer of extra large size bearing, be provided with support body, support body is annular, on support body, be provided with the pocket hole that roller is installed, upper-end surface at support body, the end face of lower end surface and inner peripheral surface is provided with drainage trough, described drainage trough is set in distance on each end face of support body, between the groove top of two adjacent drainage troughs, spacing is 20-30 ㎜, the drainage trough of upper-end surface and lower end surface radially arranges along support body, the drainage trough of inner peripheral surface axially arranges along support body, described drainage trough is V-shaped groove, the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, on two plane of inclination of V-shaped groove, be arranged with guide slot, guide slot direction is extended to groove top from the bottom land of drainage trough.

The invention has the beneficial effects as follows:

One, upper-end surface at retainer, lower end surface and inner peripheral surface are provided with drainage trough, described drainage trough is V-shaped groove, when the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, between the groove top of two adjacent drainage troughs, spacing is 20-30 ㎜, the oil film better effects if now forming, the drainage trough of this structure and can play beyond thought effect in loading process simultaneously, as the oil film in V-shaped groove can produce a kind of elastic resistance in extrusion process while being subject to strong load or enormous impact, this drag is not only subdued a part of load, and in power transmittance process, avoid retainer to be directly subject to compared with damaging energetically, thereby greatly improved this class bearing effectiveness in vibration suppression, improve antiwhip and working life.

They are two years old, on two relative plane of inclination of drainage trough, be symmetrical arranged guide slot, lubricant oil is stored in groove, when this retainer is subject to certain load, lubricant oil through bottom land the guide slot that arranges along two plane of inclination to both sides Uniform Flow, rely on the stability that flows in order to keep bearing operation of lubricant oil, therefore in guided procedure, can greatly reduce the unstability of lubricant oil disordered motion, improve the effectiveness in vibration suppression of this class bearing, and owing to being provided with guide slot, speed at retainer and bearing enclose surface of contact formation oil film is faster, evidence: this structure makes bearing reduce friction in inside more than 50%, reduce heating, in using process, conventional Temperature bearing has reduced by 15-20 ℃, reduce noise and reach 10 decibels, greatly reduced vibration, improve antiwhip.

The drainage trough two, arranging on this retainer also helps storage and the revolution of lubricant oil, reduce the friction between retainer and raceway, the lubricant oil that arc oil duct stores can constantly discharge lubricant oil when pivoting support turns round, keep good lubrication effect, arc oil duct has effectively improved the lubrication effect of pivoting support, reduce the wearing and tearing between roller and raceway, increase the life-span of pivoting support.

Embodiment

As shown in the figure, a kind of low friction retainer of extra large size bearing, be provided with support body 1, support body 1 is annular, on support body 1, be provided with the pocket hole 2 that roller is installed, on the end face of upper-end surface 3, lower end surface 4 and the inner peripheral surface 5 of support body 1, be provided with drainage trough 6, this retainer in use, lubricant oil flow in drainage trough and and bearing enclose contact position form the very thin oil film of one deck, therefore make this retainer have and reduce friction, reduce bearing heating, reduce noise and reduce the object shaking.Described drainage trough 6 is set in distance on support body 1 each end face, between the groove top of two adjacent drainage troughs 6, spacing is 20-30 ㎜, this spacing is nearest distance between two adjacent drainage troughs, the drainage trough 6 of upper-end surface 3 and lower end surface 4 radially arranges along support body 1, the drainage trough 6 of inner peripheral surface 5 axially arranges along support body 1, described drainage trough 6 is V-shaped groove, the angle of V-shaped groove is 160 °, groove depth 1.5-2 ㎜, on two plane of inclination 7 of V-shaped groove, be arranged with guide slot 8, guide slot 8 directions are extended to groove top 602 from the bottom land 601 of drainage trough, the shape of described guide slot 8 is preferably used arcuate furrow, other groove shape structures all can.

The present invention is symmetrical arranged guide slot on two relative plane of inclination of drainage trough, lubricant oil is stored in drainage trough, when this retainer is subject to certain load, the bottom land of lubricant oil process drainage trough the guide slot arranging along two plane of inclination are to both sides Uniform Flow, rely on the stability that flows in order to keep bearing operation of lubricant oil, therefore in guided procedure, can greatly reduce the unstability of lubricant oil disordered motion, improve the effectiveness in vibration suppression of this class bearing, and owing to being provided with guide slot, speed at retainer and bearing enclose surface of contact formation oil film is faster, evidence: this structure makes bearing reduce friction in inside more than 50%, reduce heating, in using process, conventional Temperature bearing has reduced by 15-20 ℃, reduce noise and reach 10 decibels, greatly reduced vibration, improve antiwhip.
