Abstract

The utility model relates to a kind of noise free bearing support.This bearing support comprises bearing base and is positioned at symmetrically arranged two the pedestal fixed holes in bearing base two ends; On bearing base, be provided with a bearing bore, be provided with the bearing for support rotating axle in bearing bore, this bearing comprises outer ring, inner ring, rolling element; Rolling element is between inner ring and the raceway of outer ring; Bearing base is one-body molded; In inner ring, have axis hole, have uniformly some towards the open-topped oil groove of axis hole in the inwall surrounding of this axis hole.Bearing base of the present utility model is one-body molded, has reduced wall thickness, has obviously reduced weight, realizes the minimizing of the fuel consume in vehicle internal combustion engine.Simultaneously owing to having uniformly oil groove at shaft hole inner wall and can directly reduce the rubbing surface of camshaft and shaft hole inner wall, the fitting surface high lubricating effect of the bearing of camshaft of the present utility model and bearing support, camshaft rotational resistance is little, the Energy Intensity Reduction that causes internal-combustion engine, has improved the competitiveness of product in market.

Description

A kind of noise free bearing support
Technical field
The utility model relates to a kind of bearing support, particularly relates to a kind of noise free bearing support.
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, can realize the minimizing of the fuel consume in vehicle internal combustion engine by reducing the weight of vehicle; 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sizable saving potentiality.Especially for supporting cam wheel axle, large and therefore heavier bearing support is out-of-date.Use lighter bearing support therefore will provide possibility for reducing weight.
The fitting surface lubrication effect of the bearing of camshaft and bearing support is not good, easily causes the rotational resistance of camshaft to become large, thereby causes the energy consumption of internal-combustion engine to increase, and has therefore increased fuel consume.Along with more and more higher to the requirement of quality of product and Product Precision in recent years today, the fitting surface lubrication effect of the bearing of camshaft and bearing support is not good will directly cause oil consumption to increase, and reduce the competitiveness of product in market.
Model utility content
Thereby the purpose of this utility model is to provide a kind of noise free bearing support because of lightweight energy efficient for above-mentioned shortcomings and deficiencies of the prior art, it is good and cause the high problem of oil consumption that this bearing support has not solved the fitting surface lubrication effect of bearing of camshaft of the prior art and bearing support, improves the competitiveness of product in market.
The purpose of this utility model is realized by following technological scheme.
A kind of noise free bearing support, 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 inner ring, have axis hole, have uniformly some towards the open-topped oil groove of axis hole in the inwall surrounding of this axis hole.
Wherein, described outer ring and bearing bore interference fit.
Wherein, be also laterally provided with two ring-type oil sealings between described outer ring and inner ring, these two ring-type oil sealings lay respectively at described multiple rolling elements both sides.
Compared with prior art, the advantage of noise free bearing support described in the utility model is:
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, the utility model has some towards the open-topped oil groove of axis hole uniformly in the inwall surrounding of axis hole, when camshaft is inserted after axis hole, in some oil grooves of the inwall surrounding of this axis hole, inject lubricant oil, owing to having uniformly oil groove at shaft hole inner wall and can directly reduce the rubbing surface of axle and shaft hole inner wall, reduce the friction factor of axle and axis hole, the fitting surface high lubricating effect of the bearing of camshaft and bearing support, camshaft rotational resistance is little, the Energy Intensity Reduction that causes internal-combustion engine, has improved the competitiveness of product in market.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model noise free bearing support.
In figure: 1 inner ring, 2 rolling elements, 3 outer rings, 4 oil grooves, 5 axis holes, 6 bearing bases, 7 pedestal fixed holes.
Embodiment
Further describe structure of the present utility model below in conjunction with accompanying drawing 1.
A kind of noise free bearing support, comprises bearing base 6 and is positioned at symmetrically arranged two the pedestal fixed holes 7 in bearing base 6 two ends; On described bearing base 6, be provided with a bearing bore, be provided with the bearing for support rotating axle in described bearing bore, described bearing base 6 is one-body molded.The utility model, because bearing base 6 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.
Bearing in bearing bore comprises outer ring 3, inner ring 1, rolling element 2; Rolling element 2 is between inner ring 1 and the raceway of outer ring 3; In described inner ring 1, have axis hole 5, have uniformly some towards the open-topped oil groove 4 of axis hole 5 in the inwall surrounding of this axis hole 5.Have uniformly some towards the open-topped oil groove 4 of axis hole in the inwall surrounding of axis hole 5, when camshaft is inserted after axis hole 5, to the interior injection lubricant oil of some oil grooves 4 of the inwall surrounding of this axis hole 5, owing to having uniformly oil groove 4 at axis hole 5 inwalls and can directly reduce the rubbing surface of axle and axis hole 5 inwalls, reduce the friction factor of axle and axis hole 5, the fitting surface high lubricating effect of the bearing of camshaft and bearing support, camshaft rotational resistance is little, the Energy Intensity Reduction that causes internal-combustion engine, has improved the competitiveness of product in market.
