Abstract
The invention discloses a wear resistant bearing which comprises a bearing outer ring, a bearing inner ring and an annular raceway disposed between the bearing outer ring and the bearing inner ring; a ball is disposed in the annular raceway; the ball surface is coated with an oil film layer; inner walls at two sides of the annular raceway are coated with a wear resistant layer. Because the ball surface is coated with the oil film layer, and the inner walls at two sides of the annular raceway are coated with the wear resistant layer, the wear resistant bearing has greatly improved lubricity, reduced friction loss between parts, reduced noise generated during operation, and improved bearing service life.
Description
Technical field
The present invention relates to a kind of anti-friction 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, high temperature resistant, anticorrosive, the anti-friction bearing of stable chemical performance, long service life.
For solving the problems of the technologies described above; The technological scheme that the present invention adopts is: a kind of anti-friction 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, said ball surfaces coated is covered with oil lamella, is coated with wearing layer on the inwall of said ring raceway both sides.
In preferred embodiment of the present invention, said oil lamella is a silicon nitride.
In preferred embodiment of the present invention, said oil lamella forms through the plasma enhanced chemical vapor deposition plated film.
In preferred embodiment of the present invention, said oil lamella thickness is 1-3 μ m.
In preferred embodiment of the present invention, said wearing layer is a polyether-ether-ketone.
In preferred embodiment of the present invention, said wearing layer is coated on the inwall of ring raceway both sides through laser.
In preferred embodiment of the present invention, said wearing layer thickness is 2-5 μ m.
The invention has the beneficial effects as follows: anti-friction bearing of the present invention is owing to be covered with oil lamella in the ball surfaces coated; On the inwall of ring raceway both sides, be coated with wearing layer; Improved lubricity widely; Reduced the frictional loss between the component, the noise that has produced when having reduced work, the working life of having improved bearing.
Description of drawings
Fig. 1 is the perspective view of anti-friction 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, wearing layer.
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 anti-friction 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 ball 4 surfaces coated are covered with oil lamella, are coated with wearing layer 5 on the inwall of said ring raceway 3 both sides.
Said oil lamella is a silicon nitride, and oil lamella thickness is 1-3 μ m, and it is a kind of superhard material; Itself has lubricity, and wear-resistant, is atomic crystal; Anti-oxidant during high temperature, and it can also resist thermal shock, in air, is heated to more than 1000 ℃; Sharply cooling sharply heating can be not cracked more yet.Said oil lamella forms through the plasma enhanced chemical vapor deposition plated film, and the oil lamella deposition rate of this method moulding is fast, quality of forming film good, pin hole is less, be difficult for be full of cracks.
Said wearing layer 5 is a polyether-ether-ketone, and wearing layer 5 thickness are 2-5 μ m, and said wearing layer 5 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; Anti-friction bearing of the present invention is owing to be covered with oil lamella in ball 4 surfaces coated; On the inwall of ring raceway 3 both sides, be coated with wearing layer 5, improved lubricity widely, reduced the frictional loss between the component; The noise that has produced when having reduced work, 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.
