Abstract
The utility model relates to a bearing, in particular to a roll wheel bearing. A maintenance-free wheel bearing is a copper sliding bearing; 18 equal lubricating slots are formed in the outer surface of the outer ring of the bearing along the circumference according to an inclination angle of 15 degrees between the outer surface and the radial direction of the bearing; and graphite solid lubricants for dipping phenolic resin are embedded into the slots to form three columns in a triangular manner. The utility model also relates to a maintenance-free roll wheel, of which the bearing is the maintenance-free wheel bearing. The service life of the bearing can be prolonged, the abrasion of a bearing pedestal to the wheel axle of the roll wheel is reduced, and the daily maintenance work on the bearing and the wheel is reduced to the maximum extent.
Description
Technical field
The utility model relates to bearing, relates in particular to a kind of roll wheel bearing.
Background technique
Precision rolling working roll is owing to need advance roll and extraction when roll change; Use wheel to accomplish its action as rolling element, what wheel bearing used is roller bearing, and the relative precision rolling working roll of its radial load ability is relatively low; Again because the rolling line environment is abominable; The drier oil fat that replenishes before the machine on the bearing water that is cooled is washed away, the oil quantity deficiency can't be rolled, exert all one's strength and bear in a bit fully.The situation that the rolling element crushing in using process at ordinary times, usually occurs causes bearing failure, and is stuck, brings fault for the rolling line roll change.
Summary of the invention
The utility model is intended to address the above problem, and a kind of non-maintaining wheel bearing and roll wheel are provided.The bearing of the utility model can promote bearing life, reduces the wearing and tearing of bearing support breaker roll wheel hub, has reduced the line service to bearing and wheel to greatest extent.
For addressing the above problem; A kind of non-maintaining wheel bearing, it is copper sliding bearing, the bearing outer ring outer surface is by offering lubrication groove with bearing inclined 15 degree and along circumference 18 five equilibriums; Inlay in the groove with impregnated phenolic resin graphite solid oiling agent, make it line up three row with triangular form.
A kind of non-maintaining roll wheel, its bearing are said non-maintaining wheel bearing.
The utility model utilizes the soft relatively partially characteristics that can not cause wearing and tearing to the axle body of copper material with the big characteristics of sliding bearing bearing capacity, uses the copper metallic material as base-material.In use, for the slide relative friction factor that guarantees bearing is low, reduce the wear extent of bearing; The surface inlay with graphite be base-material and with the solid lubricant of solidifying such as phenolic resin, make it line up three row with triangular form, adopt die press technology for forming to process; Make solid lubricant and axle friction through frictional heat; Form oil, powder and deposit lubricated excellent condition, both protected axle not wear and tear, make the solid lubrication characteristic eternal again.The bearing of the utility model can promote bearing life, reduces the wearing and tearing of bearing support breaker roll wheel hub, has reduced the line service to bearing and wheel to greatest extent.
Description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is done further to specify:
Fig. 1 is said non-maintaining bearing radial cross-section.
Embodiment
As shown in Figure 1; A kind of non-maintaining wheel bearing, it is copper sliding bearing 1, bearing 1 outer ring outer surface is by offering lubrication groove 2 with bearing inclined 15 degree and along circumference 18 five equilibriums; Inlay in the groove with impregnated phenolic resin graphite solid oiling agent 3, make it line up three row with triangular form.
A kind of non-maintaining roll wheel, its bearing are said non-maintaining wheel bearing 1.
Claims (2)
1. non-maintaining wheel bearing; It is characterized in that it is copper sliding bearing, the bearing outer ring outer surface is by offering lubrication groove with bearing inclined 15 degree and along circumference 18 five equilibriums; Inlay in the groove with impregnated phenolic resin graphite solid oiling agent, make it line up three row with triangular form.
2. a non-maintaining roll wheel is characterized in that, its bearing is said non-maintaining wheel bearing.
