Abstract
The utility model relates to a bearing, in particular to a novel ceramic needle bearing, belonging to the field of mechanical part manufacture. The novel ceramic needle bearing comprises an inner ring, an outer ring, a needle roller and threads, wherein the needle roller is arranged between the inner ring and the outer ring, and the threads are arranged at the edge of the outer ring. The novel ceramic needle bearing has the characteristics of simple structure and convenience in use. In the novel ceramic needle bearing, with the adoption of a ceramic material as a roller material, the problem of shortage of national expensive resources is alleviated; compared with the traditional bearing made of a copper alloy material, the novel ceramic needle bearing has the advantages that the oxidation resistance is high, the wear resistance is good, and the production cost is lowered; and meanwhile, with the arrangement of the threads, the threads of the outer ring of the bearing are closely matched and connected with the threads in an installation hole during installation, so that the connection of a fixing part and a rotary part is realized.
Description
Technical fieldThe utility model relates to a kind of bearing, concrete relates to a kind of new ceramics needle bearing, belongs to mechanical parts and makes the field.
Background techniqueIn the industry manufacturing and producing, bearing is requisite component in the course of working.It is used for the supported mechanical solid of rotation, in order to the mechanical load friction factor of reduction equipment in transmission process, thereby guarantees carrying out in order of production.At present, the kinds of bearings of domestic sale is varied, and the bearing commonly used according to the concrete needs of producing has: rolling bearing, thrust ball bearing, deep groove ball bearing, sliding bearing, friction bearing, combination bearing or the like.But in the bearing in sum, rolling element mostly adopts Cu alloy material to make.Because Cuprum alloy is relatively more expensive, is the short resource of country, therefore, adopts this kind manufacture of materials bearing just to bring serious resource loss to country.
Summary of the inventionThe utility model is in order to remedy above-mentioned technological deficiency, a kind of new ceramics needle bearing to be provided, and this bearing structure is simple, easy to use, with low cost, long service life.
The technological scheme of the utility model is: a kind of new ceramics needle bearing comprises inner ring, outer ring, needle roller and screw thread; Between needle roller arrangement and inner ring and the outer ring, marginal zone has screw thread in the outer ring.
Described needle roller is a stupalith, and composition is a silicon nitride.
The beneficial effect of the utility model is: this model utility has characteristics simple in structure, easy to use; Adopt stupalith as roller material; Not only alleviated national expensive resource problem of shortage, compared with the bearing of original Cu alloy material simultaneously, oxidative stability is high; Wear resistance is good, has reduced cost of production; The setting of screw thread simultaneously makes the screw thread of the outer ring of bearing when installing be connected with screw-thread fit in the mounting hole, is connected with revolving part with the realization fixed block.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, inner ring, 2, the outer ring, 3, needle roller, 4, screw thread.
Embodiment
