Wherein, the inner hole surface of described bearing outer ring is evenly provided with one deck self-lubricating sliding layer; The thickness of described self-lubricating sliding layer is 0.03-0.1mm; This self-lubricating sliding layer is bonded in the inner hole surface of described bearing outer ring by pyrolytic coating.
Wherein, be also provided with two annular oil seal between described bearing outer ring and bearing inner race, these two annular oil seal lay respectively at described raceway both sides.
Compared with prior art, the high temperature resistant bearing support tool of wear-resisting type described in the utility model has the following advantages:
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, axle is inserted axis hole by the utility model, adds oil in oilhole, and oil flows into the position at shaft hole inner wall and steel ball place by oil duct, high lubricating effect, bearing operation noise is low, effectively can improve the bearing failure because high-speed resistance causes, substantially increase the working life of the bearing of bearing support.
3, 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.
4, the raceway between bearing outer ring of the present utility model and bearing inner race 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.
