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 high-mechanic selflubricating flange bearing of high lubricating effect, this bearing not only bearing capacity is strong, and having solved bearing of the prior art, that required auxiliary component is installed is many, the large problem of weight after installing.
The purpose of this utility model is realized by following technological scheme.
A high-mechanic selflubricating flange bearing, comprises bearing outer ring, bearing inner race and steel ball, and described steel ball is between bearing outer ring and the raceway of bearing inner race; It is characterized in that: in described bearing inner race, have axis hole, the upper end of described axis hole has a plurality of oilholes, the oil duct that described oilhole forms runs through the inwall of connecting shaft hole and the outer side wall of bearing inner race; Raceway between described bearing outer ring and bearing inner race is the 30-50mm of being separated by between two roller path structures and two raceways; On the outer side surface of described bearing outer ring, be provided with flange, described flange extends radially outwardly along described bearing outer ring, and a plurality of through holes are set on described flange.
Further, described through hole is along the described flange of axial perforation of described bearing outer ring.
Further, in the inner hole surface of described bearing outer ring, be evenly provided with one deck self-lubricating sliding layer; The thickness of described self-lubricating sliding layer is 0.03-0.1mm.
Further, described self-lubricating sliding layer is bonded in the inner hole surface of described bearing outer ring by pyrolytic coating.
Further, be also provided with two ring-type oil sealings between described bearing outer ring and bearing inner race, these two ring-type oil sealings lay respectively at described raceway both sides.
Compared with prior art, high-mechanic selflubricating flange bearing tool described in the utility model has the following advantages:
1, the raceway between bearing outer ring of the present utility model and bearing inner race is two roller path structures, significantly promotes the load-carrying properties of bearing in the situation that not strengthening bearing boundary dimension, more meets the usage requirement of wind electricity pitch variable bearings.
2, the utility model is provided with flange on the outer side surface of bearing outer ring, bearing and flange are carried out to Integration Design, the outer shroud that is flange and bearing is designed to integrative-structure, do not need when mounted lining and back-up ring, pad, reduced bearing the required auxiliary component number in location has been installed, simplified installation procedure, avoided auxiliary component in mechanical movement, to occur damage and caused transmission system failure likelihood, reliability while having increased transmission system operation, the while has also alleviated the weight of transmission system.
3, the utility model inserts axis hole by axle, 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, 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.
Accompanying drawing explanation
Fig. 1 is that cross-sectional view is looked on the right side of the utility model high-mechanic selflubricating flange bearing.
Fig. 2 is the main TV structure schematic diagram of the utility model high-mechanic selflubricating flange bearing.
In figure: 1 bearing outer ring, 2 bearing inner races, 3 steel balls, 4 axis holes, 5 oilholes, 6 oil ducts, 7 self-lubricating sliding layers, 8 flanges, 9 through holes, 10 ring-type oil sealings.
Embodiment
Below in conjunction with accompanying drawing 1, Fig. 2, further describe structure of the present utility model.
A high-mechanic selflubricating flange bearing, comprises bearing outer ring 1, bearing inner race 2 and steel ball 3, and described steel ball 3 is between bearing outer ring 1 and the raceway of bearing inner race 2.Raceway between described bearing outer ring 1 and bearing inner race 2 is the 30-50mm of being separated by between two roller path structures and two raceways.Raceway between bearing outer ring 1 of the present utility model and bearing inner race 2 is two roller path structures, significantly promotes the load-carrying properties of bearing in the situation that not strengthening bearing boundary dimension, more meets the usage requirement of wind electricity pitch variable bearings.
