Abstract

The utility model relates to a bearing and in particular relates to an angular contact bearing. The angular contact bearing comprises an outer ring, an inner ring, rolling bodies and cages, wherein the rolling bodies are arranged between raceways of the inner ring and the outer ring, and the cages separate the rolling bodies uniformly along the peripheral direction in the raceways. The bearing is characterized in that the cages are oblique, pocket bottoms of the cages are provided with conical roots, an outer ring self-lubricating sliding layer is uniformly arranged on the inner hole surface of the outer ring, and an inner ring self-lubricating sliding layer is uniformly arranged on the outer side of the inner ring. The angular contact bearing has the advantages that the angular contact bearing has a simple structure and has a lubricating capacity far higher than that of traditional steel shafts, the materials of the angular contact bearing have the characteristic of wear and high temperature resistance, and bearing failure caused by high temperature and high speed wear can be effectively improved by adding the self-lubricating sliding layers, so that the service life of the bearing is greatly prolonged.

Description

A kind of angular contact bearing

Technical field

The utility model relates to a kind of bearing, particularly relates to a kind of angular contact bearing.

Background technique

The angular contact bearing that uses traditional design method to design is difficult to meet user's actual demand, the design that retainer pocket hole is circular arc, and this type difficulty of processing is large, size is difficult for assurance, in addition large with the steel ball area of contact, while running up, steel ball easily slides, burn, and impact is normally used.

The Chinese invention patent that application number is 201110149852.3 discloses a kind of bearing, and this bearing consists of outer ring, steel ball, retainer, inner ring; Retainer adopts the italic formula, and the bottom, pocket hole of retainer is with tang.The retainer of this patent of invention adopts the italic formula, with the design in tang pocket hole, limited the shifting amount of retainer, eliminated noise hidden danger, also alleviated the weight of retainer simultaneously, make bearing operation more efficient, but, under the high-speed and high-temperature environment, its rate of wear is sharply accelerated, bearing can lose efficacy very soon, too early bearing failure meeting causes the shut-down of whole equipment, has reduced manufacturing efficiency, has increased cost of production.

The model utility content

The purpose of this utility model is to provide for above-mentioned shortcomings and deficiencies of the prior art the angular contact bearing that a kind of cost is low, high temperature resistant, wear-resistant, bearing capacity is high and friction factor is little.

The purpose of this utility model is realized by following technological scheme.

A kind of angular contact bearing, comprise outer ring, inner ring, rolling element, retainer; Rolling element is between the raceway of inner ring and outer ring; Retainer is along the circumferential direction evenly separated rolling element in raceway; It is characterized in that: described retainer adopts the italic formula, and the bottom, pocket hole of retainer is with tang; Evenly be provided with one deck outer ring self-lubricating sliding layer on the inner hole surface of described outer ring, evenly be provided with one deck inner ring self-lubricating sliding layer on the outer side surface of described inner ring.

Further, described inner ring self-lubricating sliding layer, outer ring self-lubricating sliding layer are bonded on inner ring and outer ring by pyrolytic coating respectively.

Compared with prior art, the advantage of angular contact bearing described in the utility model:

1, the utility model is simple in structure, application is convenient, take polyimide as main self-lubricating sliding layer friction factor is low, hardness is high, lubricating ability is far away higher than traditional steel axle, its material itself has the characteristic of Wear-resistant, high-temperature resistant, by increasing this self-lubricating sliding layer, can effectively improve due to high temperature and bearing failure that at a high speed wearing and tearing cause, the working life of greatly having improved bearing.

2, the shoulder block of the both sides of Internal and external cycle of the present utility model just differs, and is the low of the shoulder block of a side wherein processing for the more steel ball of packing into, and bearing load carrying capacity is strengthened.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model angular contact bearing.

In figure: 1 inner ring, 2 inner ring self-lubricating sliding layers, 3 outer rings, 4 outer ring self-lubricating sliding layers, 5 rolling elements, 6, retainer.

Embodiment

Further describe structure of the present utility model below in conjunction with accompanying drawing 1.

A kind of angular contact bearing, comprise outer ring 3, inner ring 1, rolling element 5, retainer 6; Rolling element 5 is between the raceway of inner ring 1 and outer ring 3; Retainer 6 is along the circumferential direction evenly separated rolling element 5 in raceway; Described retainer 6 adopts the italic formula, and the bottom, pocket hole of retainer 6 is with tang.Evenly be provided with one deck outer ring self-lubricating sliding layer 4 on the inner hole surface of described outer ring 3, evenly be provided with one deck inner ring self-lubricating sliding layer 2 on the outer side surface of described inner ring 1.The thickness of described inner ring self-lubricating sliding layer 2, outer ring self-lubricating sliding layer 4 is 0.03-0.1mm.

Described inner ring self-lubricating sliding layer 2, outer ring self-lubricating sliding layer 4 are made by the Wear-resistant, high-temperature resistant antifriction material; Described Wear-resistant, high-temperature resistant antifriction material be take polyimide as main, with the glass fibre of teflon, 6-8% molybdenum disulfide and the 2-5% of 6-8%, mixes.Inner ring self-lubricating sliding layer 2, outer ring self-lubricating sliding layer 4 are bonded on described inner ring 1, outer ring 3 by pyrolytic coating respectively, spread uniformly thickness 0.03-0.1mm, and the baking oven of then putting 300 ℃ of high temperature into solidifies and to combine firmly after 10 minutes.

The composition of above-mentioned inner ring self-lubricating sliding layer 2, outer ring self-lubricating sliding layer 4 is mainly polyimide, polyimide is the exsertile tip materials of a kind of property, with its wear resistance, high temperature resistant, radioresistance and physical and mechanical properties, be widely used on the transmission positions such as industrial machinery, building machinery, business machine and Weaving device.The utility model is the characteristic of the glass fibre of teflon, 6-8% molybdenum disulfide and the 2-5% by increasing 6-8% again, has greatly reduced again friction factor, has strengthened mechanical strength.

Bearing structure described in the utility model is simple, application is convenient, take polyimide as main self-lubricating sliding layer friction factor is low, hardness is high, lubricating ability is far away higher than traditional steel axle, its material itself has the characteristic of Wear-resistant, high-temperature resistant, by increasing this self-lubricating sliding layer, can effectively improve due to high temperature and bearing failure that at a high speed wearing and tearing cause, the working life of greatly having improved bearing.

Above demonstration and described basic principle of the present utility model and major character and advantage thereof.The technology personage of the industry should understand; the utility model is not subject to the restriction of above-mentioned implementing regulations; what in above-mentioned implementing regulations and specification, describe is for principle of the present utility model is described; under the prerequisite that does not break away from the utility model principle and scope; the utility model also can have various changes and modifications, and these changes and improvements all belong in claimed the utility model scope.
