Abstract
The invention discloses a high-strength bearing, which comprises an bearing outer ring, a bearing inner ring and an annular rolling path arranged between the bearing outer ring and the bearing inner ring, wherein the annular rolling path is internally provided with a rolling ball, the section of the outer end of the bearing outer ring is trapezoid, the bearing inner ring is provided with an oil intake channel, the oil intake channel is connected with the annular rolling path, and a reinforcing layer is coated on the rolling ball. According to the high-strength bearing disclosed by the invention, because the section of the outer end of the bearing outer ring is trapezoid, the firmness of a stress point of the bearing is effectively improved, and the stress strength is enhanced; and because the bearing inner ring is provided with the oil inlet channel, when the high-strength bearing is used, lubricating oil can enter the annular rolling path through the oil intake channel, and therefore the lubricating performance of the rolling ball can be improved; and meanwhile, the reinforcing layer is coated on the rolling ball, the abrasive resistance of the rolling ball is increased and the service life of the bearing is improved.
Description
Technical field
The present invention relates to a kind of high tenacity bearing.
Background technique
Existing bearing generally comprise bearing outer ring, bearing inner race and be arranged on bearing outer ring and bearing inner race between ring raceway, be provided with ball in the ring raceway.Yet the existing bearing lubrication effect is relatively poor, after long-term the use, and the wearing and tearing that are prone to get rusty of the surface of ball and ring raceway thereof, and noise is very big, need make regular check on replacing, has improved cost.
Summary of the invention
The technical problem that the present invention mainly solves provides that a kind of high lubricating effect, noise are little, the high tenacity bearing of force bearing point firm, stable, long service life.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of high tenacity bearing is provided, comprise bearing outer ring, bearing inner race and be arranged on bearing outer ring and bearing inner race between ring raceway, be provided with ball in the said ring raceway; The outer end section of said bearing outer ring is trapezoidal; Offer oil inlet passage on the said bearing inner race, said oil inlet passage is connected with ring raceway, is coated with reinforced layer on the said ball.
In preferred embodiment of the present invention, the filler opening of said oil inlet passage is arranged on bearing inner race one side.
In preferred embodiment of the present invention, said reinforced layer is a polyether-ether-ketone.
In preferred embodiment of the present invention, said reinforced layer thickness is 0.2-0.5 μ m.
In preferred embodiment of the present invention, said reinforced layer is coated on the inwall of ring raceway both sides through laser.
The invention has the beneficial effects as follows: high tenacity bearing of the present invention is enhanced by force intensity because the outer end section of bearing outer ring is the trapezoidal soundness that can effectively improve shaft strength point, owing to offer oil inlet passage on the bearing inner race; During use, lubricant oil gets in the ring raceway through oil inlet passage, can improve the greasy property of ball; Simultaneously; Owing to be coated with reinforced layer on the ball, increased the wear resistance of ball, improved the working life of bearing.
Description of drawings
Fig. 1 is the perspective view of high tenacity bearing one preferred embodiment of the present invention;
The mark of each parts is following in the accompanying drawing: 1, bearing outer ring, 2, bearing inner race, 3, ring raceway, 4, ball, 5, oil inlet passage.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1, the embodiment of the invention comprises:
A kind of high tenacity bearing; Comprise bearing outer ring 1, bearing inner race 2 and be arranged on bearing outer ring 1 and bearing inner race 2 between ring raceway 3; Be provided with ball 4 in the said ring raceway 3, said bearing outer ring 1 outer end section is trapezoidal, offers oil inlet passage 5 on the said bearing inner race 2; Said oil inlet passage 5 is connected with ring raceway 3, is coated with reinforced layer on the said ball 4.
The filler opening of said oil inlet passage 5 is arranged on bearing inner race 2 one sides, and lubricant oil gets into from filler opening, and it is lubricated to get into 3 pairs of balls of ring raceway 4 through oil inlet passage 5.
Said reinforced layer is a polyether-ether-ketone, and reinforced layer thickness is 0.2-0.5 μ m, and said reinforced layer is coated on the inwall of ring raceway 3 both sides through laser.Polyether-ether-ketone high temperature heat-resistant performance is very outstanding, can use at 250 ℃ down long-term, moment serviceability temperature can reach 300 ℃; Its rigidity is big, dimensional stability, and linear expansion coefficient is less, approaches metal aluminium section; The polyether-ether-ketone chemical stability is good, and acid, alkali and nearly all organic solvent are all had very strong anti-corrosion capacity, has performances such as fire-retardant, radioresistance simultaneously; The excellent performance of anti-skimming wear of polyether-ether-ketone and fretting wear especially can keep high wear resistance and low friction coefficient down at 250 ℃; In addition, polyether-ether-ketone is easy to extrude and injection moulding.
Compared with prior art, high tenacity bearing of the present invention is enhanced by force intensity because bearing outer ring 1 outer end section is the trapezoidal soundness that can effectively improve shaft strength point; Owing to offer oil inlet passage 5 on the bearing inner race 2, during use, lubricant oil gets in the ring raceway 3 through oil inlet passage 5; Can improve the greasy property of ball 4, simultaneously, owing to be coated with reinforced layer on the ball 4; Increased the wear resistance of ball 4, the working life of having improved bearing.
The above is merely embodiments of the invention; Be not so limit claim of the present invention; Every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
