Abstract

The utility model relates to the technical field of thrust bearings, in particular to a water-turbine ceramic thrust bearing. The water-turbine ceramic thrust bearing comprises a thrust runner collar and a thrust bearing bush, wherein the lower surface of the thrust runner collar, contacted with the thrust bearing bush, is coated with a first ceramic layer, and the upper surface of the thrust bearing bush, contacted with the thrust runner collar, is coated with a second ceramic layer. The water-turbine ceramic thrust bearing is strong in abrasion resistance, corrosion resistance and self-lubricating ability, and relatively long in service life.

Description

Water turbine pottery thrust-bearing

Technical field

The utility model relates to the technical field of thrust-bearing, especially a kind of water turbine pottery thrust-bearing.

Background technique

Runner plate in the thrust-bearing of existing water turbine and wear-resisting property and the corrosion resistant performance of thrust bearing segment are generally relatively poor, runner plate and thrust bearing segment are easy to cause wearing and tearing and corrosion in long-term using process, thereby cause shorten greatly the working life of thrust-bearing.

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 water turbine pottery thrust-bearing, because the upper surface with thrust bearing segment on the lower surface of the runner plate of runner plate and thrust bearing segment touching position all is coated with ceramic layer, so wear resistance, rotproofness and the self-enrichment of water turbine pottery thrust-bearing are improved, and also prolong working life greatly.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of water turbine pottery thrust-bearing, have runner plate and thrust bearing segment, be coated with first ceramic layer on the lower surface of the runner plate of runner plate and thrust bearing segment touching position, be coated with second ceramic layer on the upper surface of runner plate and the contacted thrust bearing segment of thrust bearing segment.

The beneficial effects of the utility model: the upper surface with thrust bearing segment on the lower surface of the runner plate of water turbine pottery thrust-bearing of the present utility model and the runner plate of thrust bearing segment touching position all is coated with ceramic layer, so wear resistance, rotproofness and the self-enrichment of water turbine pottery thrust-bearing are all improved accordingly, and also prolong greatly its working life.

Description of drawings

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

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the enlarged view at A place among Fig. 1.

Among the figure 1, runner plate, 1-1, first ceramic layer, 2, thrust bearing segment, 2-1, second ceramic layer.

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.

Water turbine pottery thrust-bearing as depicted in figs. 1 and 2, have runner plate 1 and thrust bearing segment 2, be coated with the first ceramic layer 1-1 on the lower surface of the runner plate 1 of runner plate 1 and thrust bearing segment 2 touching positions, be coated with the second ceramic layer 2-1 on the upper surface of runner plate 1 and thrust bearing segment 2 contacted thrust bearing segments 2.

Because of on the lower surface of runner plate 1 and the runner plate 1 of thrust bearing segment 2 touching positions and the upper surface of thrust bearing segment 2 all be coated with ceramic layer, so wear resistance, rotproofness and the self-enrichment of water turbine pottery thrust-bearing are all improved accordingly, and also prolong greatly its working life.

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.
