Abstract
The utility model discloses a bearing long in service life. The bearing comprises bearing outer races, bearing inner races, and annular rollaway nests arranged between the bearing outer races and the bearing inner races, wherein balls are arranged in the annular rollaway nests; a shaft hole is formed in the centers of the bearing inner races; the bearing inner races are provided with oil passages penetrating through the shaft hole and the annular rollaway nests; and wear resistant layers are coated on the inner side walls of the two sides of the annular rollaway nests. According to the bearing, the wear resistant layers are coated on the inner walls of the annular rollaway nests between the bearing outer races and the bearing inner races, the bearing inner races are provided with the oil passages, and the oil passages can be used for injecting lubricating oil regularly, so that the lubricity is improved greatly, frictional losses between the balls and the annular rollaway nests are reduced, noises generated during bearing working are reduced, the service life of the bearing is prolonged, and the using cost is lowered.
Description
Technical field
The utility model relates to a kind of bearing, is meant a kind of bearing of long perfomance life more specifically.
Background technique
Bearing is a kind of base components important in all kinds of machineries that is widely used in, be used for motions such as bearing load and work rotate, swing or come and go, bearing generally comprise bearing inner race, bearing outer ring and be arranged on bearing inner race and bearing outer ring between ring raceway, be provided with ball in the ring raceway.
Yet the lubrication effect of existing bearing is relatively poor, bearing in use for some time, ball and ring raceway surface thereof get rusty easily or wear and tear, and cause bearing noise big, shorten the working life of ball, need make regular check on and change, and have increased user cost.Therefore, be necessary bearing structure is improved to improve its working life.
The model utility content
The utility model provides a kind of bearing of long perfomance life, to solve the existing bearing shortcomings such as wearing and tearing, noise is big and lack working life of easily getting rusty.
The utility model adopts following technological scheme:
A kind of bearing of long perfomance life, comprise bearing outer ring, bearing inner race and be located at bearing outer ring and bearing inner race between ring raceway, be provided with ball in the described ring raceway, described bearing inner race center is provided with an axis hole, described bearing inner race is provided with the oil duct that connects axis hole and described ring raceway, is coated with a wearing layer on the madial wall of described ring raceway both sides.
In preferred embodiment of the utility model, above-mentioned wearing layer is a polyethers ether copper layer, and wearing layer thickness is the 5-10 micron.
In preferred embodiment of the utility model, above-mentioned oil duct is four, and evenly distributes along the circumference of described bearing inner race.
By above-mentioned description to the utility model structure as can be known, compare the utility model tool with prior art
Following advantage is arranged: the bearing of this structure, on the ring raceway inwall between bearing outer ring and the bearing inner race, be coated with a wearing layer, bearing inner race is provided with oil duct simultaneously, can regularly inject lubricant oil for it, improve lubricity greatly, reduced the frictional loss between ball and the ring raceway, the noise that has produced when having reduced bearing working, improve the working life of bearing, reduced user cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described with reference to the accompanying drawings.
With reference to Fig. 1, a kind of bearing of long perfomance life, comprise bearing outer ring 1, bearing inner race 2 and be located at bearing outer ring 1 and bearing inner race 2 between ring raceway 3, be provided with ball 4 in the ring raceway 3, be coated with a wearing layer 31 on the madial wall of ring raceway 3 both sides.
Continuation is with reference to Fig. 1, and above-mentioned bearing inner race 2 centers are provided with an axis hole 21, and bearing inner race 2 also is provided with the oil duct 22 that connects axis hole 21 and described ring raceway 3, and the user can regularly be that it injects lubricant oil by oil duct 22.Above-mentioned wearing layer 31 is a polyethers ether copper layer, and wearing layer 31 thickness are the 5-10 micron; Oil duct 22 is four, and evenly distributes along the circumference of described bearing inner race 2.
The bearing of this structure, on ring raceway 3 inwalls between bearing outer ring 1 and the bearing inner race 2, be coated with a wearing layer 31, simultaneously by oil duct 22 complementary injection lubricant oil, improve lubricity greatly, reduced the frictional loss between ball 4 and the ring raceway 3, the noise that has produced when having reduced bearing working in the working life of improving bearing, has reduced user cost.
Above-mentioned only is embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
