Abstract
The utility model provides a second-class bearing combination cage, belonging to the bearing fitting field. The utility model consists of two uniform cirque-type retaining rings and a plurality of columns arranged between the two retaining rings. The two ends of the columns are separately arranged in relevant column holes of the two retaining rings. A heat dissipation oil hole is arranged between two adjacent column holes of the same retaining ring; the middle of the two sides where the columns are contacted with a rolling body are separately concave internally to form a lubrication trough which is parallel to the axis of the column. The same side of the lubrication trough between two column edges is provided with an oil trough. The utility model is characterized in that the plane structure of the cirque-type retaining ring is changed into the flanging structure in the direction of the external side. As the retaining ring is changed from the plane structure to the externally flanging structure or internally flanging structure, the plane strength of the utility model is largely increased, the capability of anti-distortion and deformation resistance is reinforced, the axial bearing capability of the cage is relevantly reinforced, thus the service life of the bearing is improved, furthermore, the change of the structure relevantly saves the raw material, makes the processing easier and reduces the manufacture cost.
Description
(1) technical field
The utility model relates to a kind of Bearing fittings, specifically a kind of secondary bearing composite cage.
(2) background technique
The patent No. is that the utility model patent of ZL:200420098595.0 discloses " a kind of secondary bearing composite cage " technology.Defectives such as in this technology, the structure of back-up ring is a plane structure, in the application in practice process, exists the planar strength deficiency, and anti-twist deformability is weak and lack working life.In order to address the aforementioned drawbacks, need to increase the thickness of back-up ring, this has increased manufacture cost having wasted raw material virtually again; Increased simultaneously the own wt of retainer again, made that the frictional force between retainer and the rolling element increases, operating temperature raises, and then the working life of having reduced bearing.
(3) summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, thus provide a kind of reasonable in design, back-up ring thickness is constant or situation about suitably reducing under its intensity can increase the secondary bearing composite cage that satisfies usage requirement greatly on the contrary.
The technological scheme that its technical problem that solves the utility model adopts is:
This secondary bearing composite cage, comprise two identical circular back-up rings and be arranged on several pillars between these two back-up rings, the two ends of pillar are separately positioned in the corresponding post hole of two back-up rings, have a heat radiation oil hole in the middle of the adjacent two post holes of same back-up ring, pillar and the middle into formation lubrication groove parallel that concave respectively in contacted two sides of roller with pillar axes, for adding oil groove, its innovative point is the turnup structure of the oriented lateral direction of circular back-up ring between two pillar limits, the same side of lubrication groove.
Above-mentioned a kind of secondary bearing composite cage, thereby the outer ring of its circular back-up ring direction flange formation laterally flanging structure.
Above-mentioned a kind of secondary bearing composite cage, thereby the inner ring of its circular back-up ring direction flange formation laterally in-flanges structure.
A kind of secondary bearing composite cage of the present utility model compared with prior art, the beneficial effect that is produced is:
1) on the structural behaviour: circular back-up ring changes over flanging structure or in-flanges structure by plane structure, and its planar strength increases greatly, and anti-twist deformability strengthens, the also corresponding enhancing of the axial carrying capacity of retainer, thereby the working life of having improved bearing;
2) on the price: circular back-up ring needs the thickness of 6-7mm under situation without turn-ups; Thickness is reduced to 2-3mm and can satisfies usage requirement behind the flange, has saved raw material, makes processing easier, has reduced manufacture cost.
