Between described inner ring and outer ring, also comprise two annular oil seal, these two annular oil seal lay respectively at described multiple rolling element both sides.
Wherein, described outer ring and bearing bore interference fit.
Wherein, 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.
Compared with prior art, the advantage of refractory seal 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, the raceway between outer ring of the present utility model and inner ring is two roller path structures, the load-carrying properties of bearing are significantly promoted when not strengthening bearing boundary dimension, significantly improve the bearing capacity of bearing support when space and weight can not significantly increase, improve the competitiveness of product in market.
4, the utility model arranges annular oil seal, and energy effective sealing bearing, prevent dust from entering in raceway, bearing operation noise is low, rubs little, effectively can improve the bearing failure because high-speed resistance causes, substantially increase the working life of bearing support.
