Abstract
The utility model discloses a wear-resisting plastic bearing, including plastics inner circle, plastics outer lane, plastics holder and ball, the plastics holder is located between plastics inner circle and the plastics outer lane, the outer recess has on the plastics inner circle, the inner wall of plastics outer lane has the inner groovy, the ball free rotation just fixes a position through outer recess and inner groovy in the plastics holder, plastics inner circle both ends face is inlayed respectively and is had wear-resisting ceramic packing ring, the shaft hole both ends of plastics inner circle are inlayed respectively and are had wear-resisting ceramic packing ring, the inner aperture and the shaft hole aperture of wear-resisting ceramic packing ring equal. The advantages are that: the utility model discloses can improve wearability and radiating effect preferred.
Description
Technical Field
The utility model belongs to the technical field of the bearing, especially, relate to a wear-resisting plastic bearing.
Background
At present, the plastic bearing has wide application in industry due to the characteristics of light weight, low cost, good corrosion resistance and the like; however, due to the material characteristics of the plastic bearing, the shaft hole of the plastic bearing is easily abraded after long-time matching with the rotating shaft in use, and the heat dissipation effect is poor.
Disclosure of Invention
The utility model aims at the not enough of above-mentioned prior art existence, provide a wear-resisting plastic bearing, it has the characteristics that can improve wearability and radiating effect preferred.
In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a wear-resisting plastic bearing, includes plastics inner circle, plastics outer lane, plastics holder and ball, the plastics holder is located between plastics inner circle and the plastics outer lane, outer recess has on the plastics inner circle, the inner wall of plastics outer lane has the inner groovy, the ball free rotation just fixes a position through outer recess and inner groovy in the plastics holder, plastics inner circle both ends face is inlayed respectively and is had wear-resisting ceramic packing ring, the shaft hole both ends of plastics inner circle are inlayed respectively and are had wear-resisting ceramic packing ring, wear-resisting ceramic packing ring's inner aperture equals with the shaft hole aperture.
Preferably, the groove bottoms of the outer groove and the inner groove are respectively coated with a ceramic coating.
Preferably, the plastic holder is provided with a heat dissipation through hole.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model is embedded with the wear-resistant ceramic washer at the shaft hole, which can effectively improve the wear resistance and the heat dissipation effect after being matched with the rotating shaft, thus prolonging the service life; the ceramic coating at the bottom of the outer groove and the inner groove can improve the wear resistance between the outer groove and the ball, and meanwhile, the ceramic coating has a good heat dissipation effect.
Drawings
Fig. 1 is a schematic plan view of the present invention.
Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Example, see figure 1: a wear-resistant plastic bearing comprises a plastic inner ring 10, a plastic outer ring 11, a plastic retainer 12 and balls 13, wherein the plastic retainer 12 is provided with a plurality of accommodating cavities which are of a through structure, and the balls 13 are positioned in the accommodating cavities and can freely rotate in the accommodating cavities. The plastic retainer 12 is located between the plastic inner ring 10 and the plastic outer ring 11, an outer groove is formed in the plastic inner ring 10, an inner groove is formed in the inner wall of the plastic outer ring 11, the outer groove and the inner groove are of annular structures, the diameter of the ball 13 is larger than the distance between the plastic inner ring 10 and the plastic outer ring 11, and meanwhile the diameter of the ball is smaller than the distance between the bottom of the outer groove and the bottom of the inner groove, so that the ball 13 can be located and can rotate freely. Inlay respectively at the shaft hole both ends of plastics inner circle 10 and have wear-resisting ceramic packing ring 14, wear-resisting ceramic packing ring 14's inner aperture equals with the shaft hole aperture, and wear-resisting ceramic packing ring 14's external diameter is less than or equal to the external diameter of plastics inner circle 10, can avoid the wearing and tearing of plastics inner circle 10 shaft hole port through this structure setting, improves wear-resisting effect, and plastics are compared to pottery simultaneously still have better radiating effect, makes life obtain the extension like this. The bottoms of the outer grooves and the inner grooves are respectively coated with the ceramic coatings, the ceramic coatings can improve the wear resistance between the ceramic coatings and the balls, and meanwhile, the ceramic coatings have a good heat dissipation effect. The plastic retainer 12 is provided with a heat dissipation through hole, which can further dissipate heat attached to the ball 13 during operation to the outside, thereby further improving the heat dissipation effect.
