Description
Technical field
The invention belongs to field of bearings, specifically a kind of self-lubricating bearing.
Background technology
Bearing is a kind of important spare part in contemporary mechanical equipment.Its major function is the mechanical rotary body of support, is reduced
Friction coefficient in its motion process, and ensure its rotating accuracy.It should be support to study carefully for it is acted on, i.e., literal interpretation is used for
Hold axis.Bearing can be divided into rolling bearing and sliding bearing, wherein rolling bearing needs are lubricated and are sealed to ensure bearing
Normal operation.The lubrication mesh of rolling bearing is reduced Bearing inner friction and abrasion, prevents from burning viscous or prevents from getting rusty, corrodes it
Effect.The lubricating method of bearing, is divided into grease lubrication and oil lubrication.If only considering lubrication, the lubricity of oil lubrication is dominant.But
It is that grease lubrication has the speciality that can simplify bearing surrounding structure, grease lubrication and the pros and cons of oil lubrication is compared.It is special when lubrication
Notice that dosage, either oil lubrication or grease lubrication, amount lubricate insufficient influence bearing life very little, amount will produce big too much
Resistance influences rotating speed and can cause to waste.The sealing of bearing be exactly in order to prevent dust, water and other sundries from entering bearing, and
Lubricant is prevented to be lost in.The sealing of bearing can be divided into included sealing and two classes of additional sealing.The additional sealing of bearing is divided into be connect to be non-
Two kinds of touch sealing and contact seal.Wherein non-contacting seal is suitable for high speed and high temperature applicationss, bearing on the market are close
Envelope is generally divided into contact seal and non-contacting seal, and contact seal is caused since sealing element and counterpart are in direct contact
It rubs when work larger, easily causes insufficient lubrication, sealing effect and performance is caused to decline；Non-contacting seal is due at work
Do not generate frictional heat, do not wear, thus be only suitable for high speed and high temperature applicationss, the lubrication and sealing problem of bearing it is urgently to be resolved hurrily.
Patent document 1：A kind of sealed rolling bearing of sand roller tug device, application number：2012200371597
Patent document 2：A kind of rolling bearing, application number：201310421419X
In above patent document 1, in order to realize the sealing of rolling bearing, needing will be by bearing seal in tugboat intracoelomic cavity
In, so that sand-lime is cannot be introduced into rolling bearing, greatly improves the service life of rolling bearing, but cage structure in tugboat body
Complexity, seal process is cumbersome, virtually increases the sealing cost of rolling bearing.
In above patent document 2, by the way that multiple interior grooves are arranged, make to maintain fluid lubricant in interior grooves, have
Effect ground forms the oil film for lubrication, and by the way that the kollag in exterior groove is arranged, and fluid lubricant immerses the solid
Lubricant can improve greasy property, but fluid lubricant is emulsified from the inner recess outflow on inner race track face with solid
When agent is merged, leaking for fluid lubricant is easily caused, to result in waste of resources, influences lubricant effect.
Invention content
