Abstract
The invention discloses a high-lubricating thrust bearing, which comprises a shaft ring, a pedestal ring, and a retainer positioned between the shaft ring and the pedestal ring and provided with a plurality of rolling bodies. The shaft ring is provided with an axial annular turnover edge along the inside diameter thereof, and the annular turnover edge carries out radial positioning for the retainer through a plurality of press claws on the edge thereof; and simultaneously, the pedestal ring is also provided with an axial annular turnover edge along the outside diameter thereof, and the annular turnover edge carries out radial positioning for the retainer through a plurality of press claws on the edge thereof. The high-lubricating thrust bearing is characterized in that the two annular turnover edges are provided with a lubricating oil passage. Because the lubricating oil passages are arranged on the shaft ring and the pedestal ring, smooth radial flowing of lubricating oil in the bearing is ensured, the flow rate of the lubricating oil is improved, and the activity of radial flowing of lubricating oil in the bearing is greatly improved, so that the lubricating oil can implement effective and sufficient lubrication for the bearing. Therefore, the integral durability and service life of the high-lubricating thrust bearing are greatly superior to those of the conventional thrust bearing.
Description
Technical field
The present invention relates to a kind of thrust-bearing, especially a kind of high-lubricating thrust bearing.
Background technique
Existing conventional thrust-bearing generally includes blowout patche, seat ring and is positioned between the two and is equipped with the retainer of some rolling elements; In order to prevent that retainer from producing play when the bearing working, influence the bearing control accuracy, also consider simultaneously the complexity of partial installation, blowout patche and seat ring all position retainer in the existing thrust-bearing, its concrete structural type is: the internal diameter along blowout patche is provided with axial annular flange, and this annular flange carries out radial location by some paws of being located on its edge to retainer; External diameter along seat ring also is provided with axial annular flange simultaneously, and this annular flange carries out radial location by some paws of being located on its edge to retainer.
Yet the structure as above-mentioned this thrust-bearing but exists very big defective at present: because two annular flange on blowout patche and the seat ring have been sealed the Internal and external cycle anchor ring of retainer respectively from both sides, make lubricant oil can only rely on blowout patche or seat ring to flow into the micro-gap that leaves between retainer and the outflow retainer reluctantly, flow is little, it is very not smooth to flow, greatly reduce the activity of lubricant oil Radial Flow in bearing, cause lubricant oil to go up substantially and can't effectively implement to lubricate bearing.Therefore usually because of lubricated insufficient early failue that causes, durability and working life are all shorter when work for existing this class thrust-bearing.
Summary of the invention
The present invention seeks to: provide a kind of high lubricating effect, the high-lubricating thrust bearing of long service life.
Technological scheme of the present invention is: a kind of high-lubricating thrust bearing comprises blowout patche, seat ring and is positioned between the two and is equipped with the retainer of some rolling elements; Described blowout patche is provided with axial annular flange along its internal diameter, and this annular flange carries out radial location by some paws of being located on its edge to retainer; Seat ring also is provided with axial annular flange along its external diameter simultaneously, and this annular flange carries out radial location by some paws of being located on its edge to retainer; Be equipped with grease channel on described two annular flange.
Grease channel described in the present invention preferably evenly is distributed on the corresponding annular flange.
Grease channel described in the present invention, its form can be the openings on the annular flange, also can be the holes of getting on the annular flange.
Paw described in the present invention also preferably is evenly distributed on the edge of respective annular flange.
The present invention is when concrete the use, and is the same with prior art, seat ring is fixed with bearing support or similar supporter, and blowout patche is fixing with axle; It in the running, lubricant oil on the axle flows in the retainer from the grease channel on the blowout patche annular flange endlessly, and under retainer and the formed centrifugal motion effect of inner rolling element high speed rotating thereof, accelerate Radial Flow, bearing inside is carried out lubricated fully, grease channel from the seat ring annular flange flows out then, has guaranteed can continue in the bearing to form continuous and sufficient lubricating film.
Advantage of the present invention is:
1. this high-lubricating thrust bearing of the present invention, owing on blowout patche and seat ring, be provided with grease channel, guaranteed lubricant oil Radial Flow unimpeded in bearing, improved flow of lubrication, improved the activity of lubricant oil Radial Flow in bearing greatly, make to continue to form continuous and sufficient lubricating film in the bearing, improved lubrication effect, guarantee that lubricant oil can implement effectively and lubricated fully bearing; So durability of integral body of the present invention and all be better than conventional thrust-bearing working life greatly.
Though the present invention is the slight improvements of being done on existing conventional thrust-bearing, but its actual effect highly significant of obtaining and outstanding: pass through comparative trial, high-lubricating thrust bearing of the present invention is compared the existing conventional thrust-bearing, its flow rate of lubricating oil has improved more than 3 times, then be increased to 3 times of conventional L10 average life, indivedual even reach 5 times of L10.
2. this high-lubricating thrust bearing of the present invention, it not only provides the oil circuit for the lubricant oil Radial Flow by on blowout patche and seat ring grease channel being set, and the wind path for the cooling air Radial Flow also is provided; Cooling air is walked inside and outside bearing fast when it turns round, produce self cooled effect, compare conventional thrust-bearing, can reduce the temperature of retainer and inner rolling element thereof greatly, reduce their loss, can improve the durability and the working life of bearing integral equally.
