Description
Technical field
The present invention relates to a kind of chain roller, especially one kind to exempt from lubricating chain roller.
Background technique
Chain conveyer is that the movement of the drive sprocket with special tooth profile and power are transmitted to special tooth by chain
A kind of kind of drive of the driven sprocket of shape.Chain conveyer has many advantages, and compared with V belt translation, nonelastic sliding and skidding are existing
As average ratios are accurate, reliable operation, high-efficient；Transmitting power is big, and overload capacity is strong, the transmission size under identical operating condition
It is small；Required tensile force is small, and the pressure acted on axis is small；Can in high temperature, humidity, more dirt, have pollution etc. and work in adverse circumstances.
But chaindriven disadvantage is also obvious, and especially transmission stability is poor, and the precision of transmission is low, and it is at high cost, easily
Abrasion easily extends, and when operating can generate additional dynamic load, vibration, impact and noise.Therefore chain at work, needs
The position addition that roller and sleeve produce relative rotation is lubricated, reduces abrasion, reduces noise, while can also extend using the longevity
Life.
Currently, the lubrication of chain roller addition is mostly lubricating oil, the lubricating oil and mostly industrial lubricant, meanwhile, roller
Entire roller can be polluted so that lubricating oil is easy to overflow outside roller due to the defect of sealing after addition lubricating oil, it is also possible to
Other articles, especially foodstuff industry can be polluted, industrial lubricant is easy contaminated food products, influence the quality of food, and in order to
Guarantee that roller continues to keep the state of lubrication, also lubricating oil irregularly is added to roller, influence the continuity of entire operation.
Therefore a kind of structure that roller is new is needed, lubrication and pollution roller and ambient can be played the role of
Product will not influence the continuity of entire operation without periodically lubricating oil is added to roller.
Summary of the invention
The present invention solves existing roller and reduces by way of adding industrial lubricant the frictional resistance of roller, subtracts
The abrasion of few roller, be easy to cause lubricating oil to overflow and pollutes the defect of roller and periphery article, provide one kind and exempt from lubricating chain
Roller is arranged the copper sheathing of the graphite with lubrication in the inner wall of roller, and graphite is immersed in food-grade oil under stress,
Both can guarantee has enough lubricities between roller and sleeve, reduce rollers wear, improves roller and rotates happy property, simultaneously also
It is avoided that the article of lubricating oil exudation pollution roller and periphery.
This invention also solves lubricating oil after existing rollers wear to be not easy to keep here, and the defect of lubricant effect decline mentions
Exempt from lubricating chain roller for one kind, a copper sheathing is arranged in the inner wall of roller, and copper sheathing is internally provided with graphite, and graphite has and copper sheathing
The lubricant housings that inner surface matches, immerses graphite for food-grade oil under stress, does not have to add lubricating oil to roller again, even if
Roller is worn, and lubrication can be played by also playing the role of enough graphite, enhances the effect of lubrication.
The technical solution adopted by the present invention to solve the technical problems is: one kind exempting from lubricating chain roller, including outside steel
Set and copper inner sleeve embedded in outer casing inner wall, are provided with the graphite mounting portion of connection copper inner sleeve inner wall in copper inner sleeve, and
