Abstract
The utility model discloses a conical roller bearing with a self-lubricating function. The conical roller bearing comprises an outer ring and a plurality of inner ring assemblies, wherein the inner ring assemblies are mounted in the outer ring; the inner ring assemblies comprise a framework-shaped retainer and an inner ring; the inner ring is sleeved with the framework-shaped retainer; the framework-shaped retainer is embedded with a plurality of tapered rollers; the tapered rollers are coated with self-lubricating material layers; and a dust-proof cover plate is mounted between the outer ring and the framework-shaped retainer. According to the conical roller bearing with the self-lubricating function, the two inner ring assemblies are symmetrically mounted in the outer ring so that the conical roller bearing can bear a great radial load and has a high limit speed; the tapered rollers are coated with the self-lubricating material layers and the bearing still has a low friction coefficient under the condition of not adding a lubricant, so that the reliability of the bearing can be guaranteed when the bearing is operated at a high speed; and the dust-proof cover plate can effectively prevent dust and impurities from entering the inner ring assemblies of the bearing and the service life of equipment is prolonged.
Description
[technical field]
The utility model relates to the technical field of tapered roller bearing, particularly has the technical field of the tapered roller bearing of self-lubricating function.
[background technique]
Bearing is in mechanical transmission course, to work the parts of fixing and reducing load friction factor.Also can say, in the time that other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in power transmission process.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, the mechanical load friction factor in order to reduction equipment in transmission process.Although the friction factor of the tapered roller bearing of prior art is less much than sliding bearing, but tapered roller bearing is installed in comparatively airtight mechanical structure mostly, add comparatively difficulty of lubricant oil, be difficult to comprehensively bearing is lubricated to maintenance, and lubricated inadequate bearing is running up the lower wearing and tearing that easily cause, cause the working life of bearing lower.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of tapered roller bearing with self-lubricating function is proposed, can in the situation that not add oiling agent, appoint and so make bearing there is lower friction factor, ensure the reliability of bearing in the time running up, extended the working life of bearing.
For achieving the above object, the utility model proposes a kind of tapered roller bearing with self-lubricating function, comprise outer ring and some inner ring assemblies, described inner ring assembly is installed in outer ring, described inner ring assembly comprises shaped as frame retainer and inner ring, and described shaped as frame retainer is set on inner ring, is embedded with some conical rollers on shaped as frame retainer, on described conical roller, be coated with self lubricating material layer, between described outer ring and shaped as frame retainer, dust cover be installed.
As preferably, the quantity of described inner ring assembly is two, and two inner ring assembly symmetries are installed in outer ring, and the internal surface of described outer ring is provided with pyramidal projections structure, makes tapered roller bearing can bear larger radial load, and has higher limit speed.
As preferably, described dust cover comprises mounting plate and dust guard, and described mounting plate is between outer ring and shaped as frame retainer, and dust guard lid is located at the surface of shaped as frame retainer and inner ring, and dust cover can prevent that dust, impurity from entering in bearing.
As preferably, described dust guard adopts fixed plate and nut to be fixedly installed in inner peripheral surface, and dust cover is installed more firm.
As preferably, the upper surface of described conical roller contacts with the internal surface of outer ring, the lower surface of conical roller contacts with the outer surface of inner ring, described self lubricating material layer is polyflon layer, make bearing appoint so to hold in the situation that not adding oiling agent and there is lower friction factor, extended the working life of bearing.
The beneficial effects of the utility model: the utility model is by two inner ring assemblies of symmetrical installation in outer ring, make tapered roller bearing can bear larger radial load, and there is higher limit speed, by apply self lubricating material layer on conical roller, make bearing appoint so to hold in the situation that not adding oiling agent and there is lower friction factor, ensure the reliability of bearing in the time running up, dust cover can effectively stop dust, impurity to enter in the inner ring assembly of bearing, has extended the working life of equipment.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
