Abstract
The invention relates to a high-speed ceramic ball bearing, and belongs to the field of rolling bearings. The technical key point is that a groove is formed between an outer ring and a middle ring of the bearing; a rolling body ceramic ball is arranged in a retainer and is embedded into the groove between the outer ring and the middle ring; a groove is arranged between the middle ring and an inner ring of the bearing; and the rolling body ceramic ball is arranged in the retainer and is embedded into the groove between the middle ring and the inner ring, wherein the middle ring combines the functions of both the inner ring and the outer ring. Due to the design of a dual-layer structure, the rotate speed and abrasion performance of the bearing are improved, and the service life of the bearing is prolonged. A bearing rolling body is a silicon nitride ceramic ball, the outer ring and the inner ring are made of GCr15 bearing steel, and the retainer is made of a nylon material.
Description
Technical fieldThe present invention relates to a kind of rolling element and be spherical bearing, the bearing that specifically to relate to a kind of high speed scroll body be ceramic ball.
Background techniqueBearing is widely used in the civilian nearly all industries of national defence such as machine-building, Aero-Space, communications and transportation, the energy, electric power, mining, metallurgy, building, chemical industry, IT, household electrical appliances.Rolling bearing is that a kind of axle that will turn round and the sliding friction between the axle bed become rolling friction, thus the mechanical component of a kind of precision of the loss of reducing friction, and the rolling bearing when being used for high speed rotating generally uses precision bearing.Rolling bearing is in the process that runs up, and rolling element will produce centrifugal force, and centrifugal action is in bearing ring, and it and plus load produce contact stress to lasso together.Contact stress is the main cause that bearing fatigue destroys.The way that addresses this problem at present is that rolling element adopts silicon nitride ceramic material, because the density of silicon nitride ceramic material approximately has only about 40% of Bearing Steel, the centrifugal force of generation also has only 40%.Because silicon nitride ceramic material is difficult to processing especially, in process of manufacture, technically be difficult to satisfy satisfactory ball bearing.
Summary of the inventionDefective in view of prior art exists the objective of the invention is to provide a kind of rotating speed height, the rotating speed that can reach capacity, long service life, wear-resisting ceramic ball bearing.
For achieving the above object, the technology used in the present invention solution is: be provided with groove between bearing outer ring and the centre circle, the rolling element ceramic ball is contained in the retainer, and in the groove between embedding outer ring and the centre circle; And between bearing centre circle and inner ring, be provided with groove, and the rolling element ceramic ball is contained in the retainer, and embeds in the groove between centre circle and the inner ring, and centre circle both plays as inner ring, again as the effect of outer ring.This double-deck design of the present invention has improved the rotating speed and the wear resistance of bearing, has prolonged the working life of bearing.Bearing roller adopts silicon nitride ceramic ball, and outer ring and inner ring adopt the GCr15 Bearing Steel, and retainer adopts nylon material.
Because the present invention has the rotating speed height, the rotating speed that can reach capacity, long service life, wear-resisting characteristics have reduced entreprise cost, are a kind of new products with promotional value.

Fig. 1 is a structural representation sketch of the present invention;
Reference character shown in Figure 1 is as follows: 1, outer ring, 2, retainer, 3, ceramic ball, 4, centre circle, 5, inner ring.
Embodiment
The specific embodiment of the present invention is: be provided with groove between bearing outer ring 1 and the centre circle 4, rolling element ceramic ball 3 is contained in the retainer 2, and in the groove between embedding outer ring 1 and the centre circle 4; And between bearing centre circle 4 and inner ring 5, being provided with groove, rolling element ceramic ball 3 is contained in the retainer 2, and in the groove between embedding centre circle 4 and the inner ring 5.Bearing roller adopts silicon nitride ceramic ball 3, and outer ring 1, centre circle 4 and inner ring 5 adopt the GCr15 Bearing Steel, and retainer 2 adopts nylon material.
