A kind of single-groove grooved ball bearing
Technical field
The utility model belongs to technical field of bearing processing, is a kind of single-groove grooved ball bearing.
Background technique
Rolling bearing is widely used important mechanical basic part, is widely used in national economy and Defence business every field.Retainer partly wraps up all or part of rolling element, and the bearing parts of movement therewith, in order to separation roller, also guides rolling element usually and holds it in the bearing.
Rolling bearing is when work; Owing to sliding friction causes bearing heating and wearing and tearing, under the high temperature operation condition, the effect of inertial centrifugal force has aggravated friction, wearing and tearing and heating especially; Can cause retainer burn or fracture when serious, cause the bearing cisco unity malfunction.Therefore, assurance is lubricated effectively just seems most important.
Summary of the invention
The purpose of the utility model provides a kind of single-groove grooved ball bearing, the lubrication effect in the time of guaranteeing bearing working fully, the working life of prolongation bearing.
The technological scheme of the utility model is a kind of single-groove grooved ball bearing; Which comprises at least outer ring, inner ring, one group of steel ball and retainer, steel ball places on the hole of retainer, and groove is arranged in the middle of the inner ring; The groove that retainer and steel ball are sleeved on inner ring constitutes inner ring assembly; Inner ring assembly is with the outer ring outward, it is characterized in that: inner surface and inner ring outer surface all are furnished with some holes of hiding, and the surface of contact gap of retainer and steel ball and inside and outside circle all is filled with oiling agent.
Open lattice structure is adopted in the described hole of hiding, and the size in the hole of hiding is Φ 2.5mm*1mm, and adjacent two distances of hiding between the hole are 5mm.
Described oiling agent adopts solid lubricant, and the dosage of oiling agent uses standard freely to overflow oiling agent as the surface of contact place of retainer and steel ball and inside and outside circle.
The characteristics of the utility model are all to be furnished with some open dot matrix hole of hiding at inner surface and inner ring outer surface; The surface of contact gap of retainer and steel ball and inside and outside circle all is filled with solid lubricant simultaneously; Make it form the lubricated selfsealings effect of submarine; Prolong the working life of bearing, guaranteed the normal, steady, efficient of work.
Description of drawings
To combine embodiment that the utility model is further described below.
Fig. 1 is the structural representation of single-groove grooved ball bearing.
Fig. 2 is the retainer structural representation.
Fig. 3 is the inner ring structural representation.
Fig. 4 is the outer ring structure schematic representation.
Among the figure: 1, outer ring; 2, inner ring; 3, retainer; 4, steel ball; 5, the hole of hiding; 6, groove; 7, hole.
Embodiment
As illustrated in fig. 1 and 2, steel ball 4 places on the hole 7 of retainer 3, and retainer 3 constitutes inner ring assembly with the groove 6 that steel ball 4 is sleeved on inner ring 2, and inner ring assembly is with outer ring 1 outward, has then constituted single-groove grooved ball bearing.Retainer 3 all is filled with solid lubricant with the surface of contact gap of steel ball 4 and inside and outside circle, and the dosage of oiling agent uses standard freely to overflow oiling agent as the surface of contact place of retainer and steel ball and inside and outside circle.
As shown in Figure 3, there is groove 6 in inner ring one week of 2 intermediate portions, can guarantee that retainer 3 is sleeved on inner ring 2 outsides, and the outer surface of inner ring 2 adopts open dot matrix to hide and cheats 5, and the size in the hole of hiding is Φ 2.5mm*1mm, and adjacent two distances of hiding between the hole are 5mm.
As shown in Figure 4, the internal surface of outer ring 1 also adopts open dot matrix to hide and cheats 5, and the size in the same hole of hiding is Φ 2.5mm*1mm, and adjacent two distances of hiding between the hole are 5mm.
During work; Steel ball 4 is fixing down in the surface friction of inner ring 2 and outer ring 1 retainer 3, because inner surface and inner ring outer surface all are furnished with some open dot matrix hole of hiding, the surface of contact gap of while retainer and steel ball and inside and outside circle all is filled with solid lubricant; Make it form the lubricated selfsealings effect of submarine; And formed lubricant film at the internal surface of outer ring and the outer surface of inner ring, prolonged the working life of bearing like this, guaranteed the normal, steady, efficient of work.
