The bearing capacity of the bearing of camshaft and bearing support is inadequate, easily causes the life-span of bearing support to reduce.But the bearing capacity that increases bearing, means the volume and weight that need to increase bearing, can directly cause like this oil consumption of internal-combustion engine to strengthen, reduce the competitiveness of product in market.The bearing capacity that how can significantly improve again bearing support in the situation that space and weight can not significantly increase is the current technical issues that need to address of those skilled in the art.
Ball between inner ring and the outer ring of the bearing in bearing support is outside exposed, airborne dust can enter in the lubricant oil of raceway, causes the frictional force between ball and raceway to increase, and bearing operation noise is large, very easily cause the bearing failure that wearing and tearing cause at a high speed, the working life of having reduced bearing support.How to eliminate the wearing and tearing of bearing after dust enters, the Security, reliability and the bearing capacity that improve bearing are the current technical issues that need to address of those skilled in the art.
Model utility content
Thereby the purpose of this utility model is to provide a kind of high-mechanic sealed bearing because of lightweight energy efficient for above-mentioned shortcomings and deficiencies of the prior art, this bearing support can not only effective sealing bearing, prevent that dust from entering in raceway, can effectively improve due to the bearing failure that wearing and tearing cause at a high speed, the working life of greatly having improved bearing support; And in the situation that can not significantly increasing, space and weight significantly improves the bearing capacity of bearing support.
The purpose of this utility model is realized by following technological scheme.
A kind of high-mechanic sealed bearing, 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 inner ring, outer ring, rolling element, retainer; Rolling element is between inner ring and the raceway of outer ring; Described retainer adopts italic formula, and the bottom, pocket hole of retainer is with tang; It is characterized in that: described bearing base is one-body molded; Between described inner ring and outer ring, also comprise two ring-type oil sealings, these two ring-type oil sealings lay respectively at described multiple rolling elements both sides; Raceway between described inner ring and outer ring is the 30-50mm of being separated by between two roller path structures and two raceways.
Wherein, described outer ring and bearing bore interference fit.
Wherein, in the inner hole surface of described outer ring, be evenly provided with one deck outer ring self-lubricating sliding layer, on the outer side surface of described inner ring, be 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 by pyrolytic coating respectively.
Compared with prior art, the advantage of high-mechanic sealed bearing described in the utility model:
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 raceway between outer ring of the present utility model and inner ring is two roller path structures, in the situation that not strengthening bearing boundary dimension, significantly promote the load-carrying properties of bearing, the bearing capacity that significantly improves bearing support in the situation that space and weight can not significantly increase, has improved the competitiveness of product in market.
3, the utility model arranges ring-type oil sealing, and energy effective sealing bearing, prevents that dust from entering in raceway, and bearing operation noise is low, rubs little, can effectively improve due to the bearing failure that wearing and tearing cause at a high speed, the working life of greatly having improved bearing support.
Brief description of the drawings
