Description
Technical field
The utility model relates to a kind of bearing support, particularly relates to a kind of noise free from cooling bearing seat.
Background technique
Bearing support in Modern Internal-Combustion Engine is the member for spring bearing and camshaft.The material of bearing support is all generally that special bearing support steel is made by various processing, better bearing support steel also has the limiting temperature of their uses.Current bearing support does not all arrange cooling unit, under use state, if temperature is too high, be easy to make bearing support surface to occur segmentation crack, the too high bearing support of temperature is also easy to occur segmentation crack meeting under cold state, the situations such as the product that causes producing occurs being out of shape, pulls, sticking to mould.
Due to the emission standard for Modern Internal-Combustion Engine increasingly stringent, make efforts especially to reduce weight, space and therefore reduce fuel consume at present.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sizable saving potentiality.Especially for supporting cam wheel axle, large and therefore heavier bearing support is out-of-date.Use lighter bearing support therefore will provide possibility for reducing weight.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
The purpose of this utility model is to provide a kind of noise free because of lightweight energy efficient from cooling bearing seat 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, improve the competitiveness of product in market, and effectively reduced the temperature of bearing support, extend the working life of bearing support.
The purpose of this utility model is realized by following technological scheme.
A kind of noise free, from cooling bearing seat, comprises bearing base and bearing bore, and described bearing bore is arranged on bearing base, is symmetrically arranged with two pedestal fixed holes at bearing base two ends; In described bearing bore, be provided with the bearing for support rotating axle, 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 bearing base, be provided with a cooling bath around bearing bore, be also provided with a cooling water tank outward at described bearing base, this cooling water tank is communicated with described cooling bath by a connecting tube; 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, described cooling water tank is mainly made up of water pump, casing and turnover water pipe, the described turnover water pipe described connecting tube that is tightly connected.
Compared with prior art, noise free described in the utility model is from the advantage of cooling bearing seat:
1, the utility model is provided with a cooling bath around bearing bore in bearing base, be communicated with cooling water tank by connecting tube, carry out cooling by cooling water to bearing support, effectively reduce the temperature of bearing support, prevent that bearing support from causing the appearance of segmentation crack because of excess Temperature, the situations such as the product of having avoided producing occurs being out of shape, pulls, sticking to mould, have extended working life of bearing support.
2, 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.
3, 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.
