Description
Technical field
The present invention relates to a kind of self oiling bearing, particularly relate to a kind of self oiling bearing that can work under rugged environment.
Background technique
Due to the requirement of special producing technique, some key equipment of industrial and mining enterprise moves under very severe operating mode.Because load is excessive, ambient temperature is high, in the large or air of dust containing sour corrosion gas CO, SO2 etc., bring a lot of problems to equipment lubricated, and fretting wear is serious, up to the present, domestic above-mentioned enterprise major part is still continued to use traditional oil, grease lubrication, and in fact these industrial and mineral conditions have exceeded scope oily, grease lubrication, and biting or killing of bearing and other friction pairs very easily occurs, cause serious parts depreciation and damage, regularly cause equipment to be stopped transport.In order to produce continuous operation, except requirement installation multiple devices wheel is repaiied in original design, also must drop into a large amount of maintenance mans.Seriously limiting the raising of productivity, standby redundancy and energy consumption are very big, have become the significant obstacle of developping production.The enterprises such as automobile making, manufacture of cement, petrochemical industry have all proposed to provide extraordinary lubriation material requirement under complex working conditions.For this reason, to self-lubricating composite research, in material prescription and preparation process, outstanding self-character, for enterprise has solved the lubrication problem under special operation condition, and has brought obvious economic and social benefit.But due to many reasons, domestic more enterprise not yet adopts, and above-mentioned condition still exists.
As can be seen here, above-mentioned existing bearing, in structure and use, obviously still has inconvenience and defect, and is urgently further improved.Therefore how to found a kind of self oiling bearing of new structure, also becoming the current industry utmost point needs improved target.
Summary of the invention
The object of the invention is to, overcome the defect that existing bearing exists, and provide a kind of self oiling bearing of new structure, technical problem to be solved is that it can be washed away at high speed, high oil gas, under the working environment of burn into high temperature, work for a long time, bearing only needs a small amount of lubricating grease, just can under rugged environment, work and reach more than 1 year, does not maintain in use or few maintenance.The lubricating grease of bearing previous work adds from bearing inside, and after later stage lubricating grease runs out of, the material of retainer can replace the effect lubricating bearings of lubricating grease, makes bearing be unlikely to stuck under the environment of dry friction, thus damage equipment.This bearing wear-resisting property is good, and friction factor is little, long service life, and the rolling element of use is ceramic ball, can rub for a long time, indeformable.This bearing also has appropriate elastoplasticity, can, by stress distribution on wider surface of contact, improve the bearing capacity of bearing.And bearing quiet, the coefficient of kinetic friction is close, thereby ensure mechanical operating accuracy.Bearing retainer material in operation process can form transfer membrane, plays the effect of protection rolling element and raceway groove.
The object of the invention to solve the technical problems realizes by the following technical solutions.A kind of self oiling bearing proposing according to the present invention, comprising: outer ring, retainer, inner ring, rolling element, dust cover; Wherein: in the raceway groove in the middle of described inner ring and outer ring, be equiped with rolling element; In the raceway groove in the middle of described inner ring and outer ring, be provided with retainer and be connected with moving rolling element; Described dust cover is arranged in one end of inner ring and outer ring;
The object of the invention to solve the technical problems also can be applied to the following technical measures to achieve further.
Aforesaid a kind of self oiling bearing, is characterized in that inner ring is provided with raceway groove.
Aforesaid a kind of self oiling bearing, is characterized in that outer ring is provided with raceway groove.
Aforesaid a kind of self oiling bearing, the material that it is characterized in that rolling element is ceramic ball.
Aforesaid a kind of self oiling bearing, is characterized in that moving in a circle in the raceway groove of rolling element in the middle of inner ring and outer ring.
The present invention compared with prior art has obvious advantage and beneficial effect.As known from the above, for achieving the above object, the invention provides a kind of self oiling bearing, comprising: outer ring, retainer, inner ring, rolling element, dust cover; Wherein: in the raceway groove in the middle of described inner ring and outer ring, be equiped with rolling element; In the raceway groove in the middle of described inner ring and outer ring, be provided with retainer and be connected with moving rolling element; Described dust cover is arranged in one end of inner ring and outer ring; In the raceway groove of rolling element in the middle of inner ring and outer ring, move in a circle, retainer guides and drives rolling element to roll on correct raceway, rolling element is equally spaced, being distributed on raceway obtains on circumference when preventing work and collides with each other and rub between rolling element, supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.
By technique scheme, a kind of self oiling bearing of the present invention at least has following advantages and beneficial effect:
1, only need a small amount of lubricating grease, just can under rugged environment, work and reach more than 1 year, do not maintain in use or few maintenance.
2, wear-resisting property is good, and friction factor is little, long service life.
3, the rolling element using is ceramic ball, can rub for a long time, indeformable.
4, bearing has appropriate elastoplasticity, can, by stress distribution on wider surface of contact, improve the bearing capacity of bearing.
5, bearing quiet, the coefficient of kinetic friction is close, thereby ensure mechanical operating accuracy.
6, bearing retainer material in operation process can form transfer membrane, plays the effect of protection rolling element and raceway groove.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of specification, and for above and other object of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
