Description
Technical field
The utility model relates to a kind of bearing support, particularly a kind of angular contact bearing seat.
Background technique
Due to the emission standard for Modern Internal-Combustion Engine increasingly stringent, make efforts especially to reduce weight, space and therefore reduce fuel consume.Especially, by reducing the weight of vehicle, can realize the minimizing of the fuel consume in vehicle internal combustion engine; Due to the high tenor of internal-combustion engine, it has sizable saving potentiality.Especially for supporting cam wheel axle, large and therefore heavier bearing support is out-of-date.Use lighter bearing support therefore will provide possibility for reducing weight.
Bearing support middle (center) bearing is equipped with retainer at present, but retainer is due to along center line symmetric design, causes retainer conventionally heavier, noise and friction are larger, the rotational resistance of camshaft and bearing support is increased, cause the Energy Intensity Reduction of internal-combustion engine, reduce the competitiveness of product in market.
Model utility content
Thereby the purpose of this utility model is to provide a kind of angular contact bearing seat because of lightweight energy efficient for above-mentioned shortcomings and deficiencies of the prior art.
The purpose of this utility model is realized by following technological scheme.
An angular contact bearing seat, comprises bearing base and is positioned at symmetrically arranged two the pedestal fixed holes in bearing base two ends; On described bearing base, be provided with a bearing bore, be provided with the bearing for support rotating axle in described bearing bore, this bearing comprises outer ring, inner ring, rolling element; Rolling element is between inner ring and the raceway of outer ring; It is characterized in that: described bearing base is one-body molded; In described raceway, be provided with for supporting the retainer of described rolling element, retainer is along the circumferential direction evenly separated rolling element in raceway; This retainer adopts italic formula, and the bottom, pocket hole of retainer is with tang.
Wherein, described outer ring and bearing bore interference fit.
Wherein, in the inner hole surface of described outer ring, be evenly provided with one deck outer ring self-lubricating sliding layer, on the outer side surface of described inner ring, be evenly provided with one deck inner ring self-lubricating sliding layer.
Wherein, described inner ring self-lubricating sliding layer, outer ring self-lubricating sliding layer are bonded on inner ring and outer ring by pyrolytic coating respectively.
Compared with prior art, the advantage of angular contact bearing seat described in the utility model is as follows:
1, the utility model, because bearing base is one-body molded, has reduced wall thickness, and the obvious weight that reduced that compared with prior art monoblock forms, realizes the minimizing of the fuel consume in vehicle internal combustion engine, reaches the object of energy-conserving and environment-protective.
2, retainer of the present utility model adopts italic formula, the bottom, pocket hole of retainer is with tang, limited the shifting amount of retainer, eliminated noise hidden danger, reduce friction, also alleviated the weight of retainer simultaneously, make the rotational resistance of camshaft and bearing support little, the Energy Intensity Reduction that causes internal-combustion engine, has improved the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the utility model angular contact bearing seat.
Fig. 2 is the right TV structure schematic diagram of the utility model angular contact bearing seat.
In figure: 1 inner ring, 2 inner ring self-lubricating sliding layers, 3 outer rings, 4 outer ring self-lubricating sliding layers, 5 rolling elements, 6 retainers, 7 pedestal fixed holes, 8 bearing bases.
Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2, further describe structure of the present utility model.
An angular contact bearing seat, comprises bearing base 8 and is positioned at symmetrically arranged two the pedestal fixed holes 7 in bearing base 8 two ends; Described bearing base 8 is one-body molded; On described bearing base 8, be provided with a bearing bore, in described bearing bore, be provided with the bearing for support rotating axle.The utility model, because bearing base 8 is one-body molded, has reduced wall thickness, and the obvious weight that reduced that compared with prior art monoblock forms, realizes the minimizing of the fuel consume in vehicle internal combustion engine, reaches the object of energy-conserving and environment-protective.
In described raceway, be provided with for supporting the retainer 6 of described rolling element 5, retainer 6 is along the circumferential direction evenly separated rolling element 5 in raceway; This retainer 6 adopts italic formula, and the bottom, pocket hole of retainer 6 is with tang.Retainer 6 of the present utility model adopts italic formula, the bottom, pocket hole of retainer 6 is with tang, limited the shifting amount of retainer 6, eliminated noise hidden danger, reduce friction, also alleviated the weight of retainer 6 simultaneously, make the rotational resistance of camshaft and bearing support little, the Energy Intensity Reduction that causes internal-combustion engine, has improved the competitiveness of product in market.
This bearing comprises outer ring 3, inner ring 1, rolling element 5; Rolling element 5 is between inner ring 1 and the raceway of outer ring 3; In the inner hole surface of described outer ring 3, be evenly provided with one deck outer ring self-lubricating sliding layer 4, on the outer side surface of described inner ring 1, be evenly provided with one deck inner ring self-lubricating sliding layer 2.The thickness of described inner ring self-lubricating sliding layer 2, outer ring self-lubricating sliding layer 4 is 0.03-0.1mm.Take polyimide as main self-lubricating sliding layer friction factor is low, hardness is high, lubricating ability is far away higher than traditional steel axle, its material itself has the characteristic of Wear-resistant, high-temperature resistant, by increasing this self-lubricating sliding layer, can effectively improve due to high temperature and bearing failure that at a high speed wearing and tearing cause, the working life of greatly having improved bearing.
