Abstract
The utility model provides a rolling bearing which is lubricated by a thermoplastic polymer maintaining solid lubrication material. The solid lubricated rolling bearing includes an outer ring, an inner ring, a rolling body embedded between the outer ring raceway and the inner ring raceway, a maintainer which uniformly separates the rolling body along the peripheral direction, and a plasticized shaped body embedded between the outer ring and the inner ring and having a function of solid lubrication. The plasticized shaped body is in contact with the rolling body and the maintainer respectively. When the bearing is working, the micro-contact and colliding between the maintainer, the roller and the plasticized shaped body cause the solid lubrication material to drop, thus a solid-transfer lubricating film is formed on a working surface of a bearing part, and the lifetime maintenance-free lubrication of the bearing is realized. So, the manufacturing cost and maintenance cost of the bearing are reduced, and the running reliability and running life of the bearing under the conditions of low temperature, ultralow temperature, high temperature and ultrahigh temperature are greatly prolonged.
Description
Technical field
The utility model relates to the technical field of extraordinary rolling bearing, particularly a kind of rolling bearing that keeps solid lubricant to be lubricated by thermoplastic polymer.
Background technique
Be operated in low temperature ultralow temperature, high temperature superhigh temperature, radiation, the invasion and attack of extensive chemical medium, vacuum and do not allow the rolling bearing of any finish under polluting arranged at goods, because lubricating grease, lubricated wet goods fluid lubricant are difficult to adapt to these operating modes, adopting solid lubricant to carry out solid lubrication often becomes best or even unique selection.
The solid lubrication rolling bearing need to be selected solid lubricant and be introduced into bearing inside, and still, existing solid lubrication rolling bearing is selected or there is following defective in the mode that solid lubricant is introduced bearing inside solid lubricant:
1, directly in bearing, adds the solid lubrication powder such as graphite, molybdenum disulfide, cause is disposable adding, the amount that adds certainly will be more, will form like this gathering of powder, the powder that is inserted between rolling element and the raceway convergence gap is too much, eliminate the due working gap of bearing, hinder the normal operation of retardance rolling element and retainer, even cause bearing stuck; If the amount of powder that adds is very few, then can cause bearing to owe lubricated, cause the wear out failure of bearing, thereby affect the service life of bearing;
2, insert spacer rod or the spacing block that the solid lubricant such as graphite is made in the bearing between per two rolling elements, spacer rod or spacing block are too much because of degrees of freedom, easy deflection in the bearing operation process, and then hinder the normal operation of retardance bearing; Again it, the spacer rod piece is only suitable in without the retainer bearing, but in a single day bearing does not have retainer, each rolling element just can not get well isolation and motion guidance; Therefore, such introducing mode is only suitable in utmost point low speed bearing;
3, adopt organic self lubricating materials such as teflon, polyether-ether-ketone to make whole coronary band fore shaft retainer and insert bearing cavity, teflon, polyether-ether-ketone do not belong to free machining material, can bring the rising of processing cost; In the bearing movable process difficulty have solid lubricant to come off, can cause the Starved Lubrication between rolling element and the raceway, thereby affect the service life of bearing;
4, adopt the inorganic self lubricating material such as carbon graphite to make whole crown retainer and insert bearing cavity, the inorganic self lubricating material such as carbon graphite, matter is hard and crisp, be difficult to processing, cutting rate is very low, and this must cause the remarkable rising of bearing cost, in addition, also to install dust cover or collar etc. additional, prevent that retainer from withdrawing from bearing vertically in the bearing operation process.
The model utility content
