Abstract

The utility model relates to the technical field of ball bearings, particularly a gate ceramic ball bearing kit which is provided with a shaft sleeve and a bearing body, wherein the shaft sleeve is arranged on the shaft in a sliding mode; the bearing body comprises a bearing outer ring and a bearing inner race which form a spherical mesh; and the inner spherical surface and of the bearing outer ring and the outer spherical surface of the bearing inner race are respectively sprayed with a ceramic layer. The gate ceramic ball bearing kit has the advantages of high wear resistance, high corrosion resistance, favorable self-lubricating property and long service life.

Description

Gate ceramic ball bearing external member

Technical field

The utility model relates to the technical field of ball bearing, especially a kind of gate ceramic ball bearing external member.

Background technique

Because gate usually is relatively to work under the rugged environment, so the requirement to the accessory on the gate is relatively harsher, generally need use ball bearing on the gate, yet the bearing outer ring on the existing ball bearing and the wear-resisting property of bearing inner race and corrosion resistant performance are relatively poor, bearing outer ring and bearing inner race are easy to cause wearing and tearing and corrosion in long-term using process, cause shorten greatly the working life of ball bearing.The self-enrichment of ball bearing is relatively poor simultaneously, in order to reduce friction, usually needs to add lubricant oil.

The model utility content

The technical problems to be solved in the utility model is: in order to solve the shortcoming and defect that proposes in the above-mentioned background, the utility model provides a kind of gate ceramic ball bearing external member, owing to all be coated with ceramic layer on the bearing outer ring inner ball surface and on the bearing inner race outer spherical surface, so wear resistance, rotproofness and the self-enrichment of gate ceramic ball bearing external member are improved, also prolong greatly working life.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of gate ceramic ball bearing external member, axle sleeve with the axle that is slidingly located in, also has bearing body, bearing body comprises bearing outer ring and the bearing inner race of sphere engagement, all is coated with ceramic layer on the bearing outer ring inner ball surface He on the bearing inner race outer spherical surface.

Further: all be coated with ceramic layer on the sleeve outer surface of axle sleeve and bearing inner race touching position and the bearing inner race internal surface.

Further: bearing outer ring is the split structure.

The beneficial effects of the utility model: all be coated with ceramic layer on the bearing outer ring inner ball surface of gate ceramic ball bearing external member of the present utility model He on the bearing inner race outer spherical surface, and all be coated with ceramic layer on the sleeve outer surface of axle sleeve and bearing inner race touching position and the bearing inner race internal surface, so make gate ceramic ball bearing external member possess stronger wear resistance, rotproofness and self-enrichment, prolong working life greatly; Simultaneously because bearing outer ring is the split structure, so bearing body is more convenient quick when assembling.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is that gate ceramic ball bearing external member is installed in the use phase diagram on the gate;

Fig. 2 is structural representation of the present utility model.

Among the figure 1, axle, 2, axle sleeve, 3, bearing body, 3-1, bearing outer ring, 3-2, bearing inner race, 4, ceramic layer, 5, gate sheet.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

Gate ceramic ball bearing external member of the present utility model is installed in the two ends of the gate sheet of plane gate, also can be installed on the upstream and downstream face of gate sheet.As shown in Figure 1, gate ceramic ball bearing external member of the present utility model is installed on the two ends and downstream face of gate sheet 5 of plane gate.

Gate ceramic ball bearing external member as shown in Figure 2, axle sleeve 2 with the axle 1 that is slidingly located in, also have bearing body 3, bearing body 3 comprises bearing outer ring 3-1 and the bearing inner race 3-2 of sphere engagement, all is coated with ceramic layer 4 on the bearing outer ring 3-1 inner ball surface He on the bearing inner race 3-2 outer spherical surface.All be coated with ceramic layer 4 on axle sleeve 2 outer surfaces of its Intermediate shaft sleeve 2 and bearing inner race 3-2 touching position and the bearing inner race 3-2 internal surface.What bearing outer ring 3-1 adopted is the split structure, so bearing body 3 is more convenient quick when assembling.

Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
