Description

A kind of high temperature resistant bearing support
Technical field
The utility model relates to a kind of bearing support, particularly relates to a kind of high temperature resistant bearing support of the camshaft for supporting internal-combustion engine.
Background technique
Bearing support in Modern Internal-Combustion Engine is used to the component of spring bearing and camshaft.The material of bearing support is all generally that special bearing support steel is made by various process, then the limiting temperature that good bearing support steel also has them to use.Current bearing support does not all arrange cooling unit, in a state of use, if temperature is too high, be easy to make bearing support surface occur segmentation crack, the too high bearing support of temperature is also easy to occur segmentation crack meeting under cold state, causes the product produced to occur being out of shape, pulls, the situation such as sticking to mould.
Due to the emission standard for Modern Internal-Combustion Engine increasingly stringent, make efforts to reduce weight, space and therefore reduce fuel consume especially.Especially, the weight by reducing 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sizable saving potentiality.Especially for supporting cam wheel axle, greatly and therefore heavier bearing support is out-of-date.Use lighter bearing support therefore will provide possibility for reducing weight.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, thus causes the energy consumption of internal-combustion engine to increase, because this increasing fuel consume.Along with today more and more higher to the requirement of quality of product and Product Precision in recent years, the fitting surface lubrication effect of the bearing of camshaft and bearing support is not good will directly cause oil consumption to increase, and reduces the competitiveness of product in market.
Model utility content
The purpose of this utility model is to provide for above-mentioned shortcomings and deficiencies of the prior art a kind of because of the lightweight thus high temperature resistant bearing support of energy efficient, this bearing support not only solves the not good and problem causing oil consumption high of the fitting surface lubrication effect of the bearing of camshaft of the prior art and bearing support, improve the competitiveness of product in market, and significantly reduce 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 high temperature resistant bearing support, comprises bearing base and is positioned at symmetrically arranged two the pedestal fixed holes in bearing base two ends; Described bearing base is provided with a bearing bore, and 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:
The inner hole surface of described outer ring is evenly provided with one deck outer ring self-lubricating sliding layer, the outer side surface of described inner ring is evenly provided with one deck inner ring self-lubricating sliding layer; Described inner ring self-lubricating sliding layer, outer ring self-lubricating sliding layer are bonded on inner ring and outer ring respectively by pyrolytic coating;
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.
Wherein, described outer ring and bearing bore interference fit.
Wherein, between described outer ring and inner ring, be also laterally provided with two annular oil seal, these two annular oil seal lay respectively at described multiple rolling element both sides.
Compared with prior art, the advantage of high temperature resistant bearing support described in the utility model:
1, the utility model is provided with a cooling bath around bearing bore in bearing base, cooling water tank is communicated with by connecting tube, by cooling water, bearing support is cooled, significantly reduce the temperature of bearing support, prevent bearing support Yin Wendu too high and cause the appearance of segmentation crack, the situations such as being out of shape, pulling appears in the product avoiding production, sticking to mould, extend the working life of bearing support.
2, the utility model due to bearing base one-body molded, decrease wall thickness, compared with prior art monoblock formed considerably reduce weight, realize the minimizing of the fuel consume in vehicle internal combustion engine, reach the object of energy-conserving and environment-protective.
3, camshaft is inserted axis hole by the utility model, bearing inner race and outer ring are provided with the self-lubricating sliding layer based on polyimide, because self-lubricating sliding layer friction factor is low, lubricating ability is far away higher than traditional steel axle, make the fitting surface high lubricating effect of the bearing of camshaft and bearing support, camshaft rotational resistance is little, causes the energy consumption of internal-combustion engine to reduce, improves the competitiveness of product in market.
Accompanying drawing explanation
Fig. 1 is the structural representation of the high temperature resistant bearing support of the utility model.
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 bearing bases, 7 pedestal fixed holes, 8 cooling baths, 9 connecting tubes.
Embodiment
Structure of the present utility model is further described below in conjunction with accompanying drawing 1.
A kind of high temperature resistant bearing support, comprises bearing base 6 and is positioned at symmetrically arranged two the pedestal fixed holes 7 in bearing base 6 two ends; Described bearing base 6 is provided with a bearing bore, in described bearing base 6, is provided with a cooling bath 8 around bearing bore, outside described bearing base 6, be also provided with a cooling water tank, this cooling water tank is communicated with described cooling bath 8 by a connecting tube 9.The utility model is provided with a cooling bath 8 around bearing bore in bearing base 6, cooling water tank is communicated with by connecting tube 9, by cooling water, bearing support is cooled, significantly reduce the temperature of bearing support, prevent bearing support Yin Wendu too high and cause the appearance of segmentation crack, the situations such as being out of shape, pulling appears in the product avoiding production, sticking to mould, extend the working life of bearing support.
