Abstract
A three-layer thrust cylinder roller bearing comprises three housing washers, three shaft washers, three retainers, a cylinder roller, an outer ring spacer and an inner ring spacer, wherein the working surfaces of the three housing washers and the working surfaces of the three shaft washers are all plate surfaces; special-shaped solid retainers are adopted by the three retainers; a plurality of rows cylinder rollers are distributed on the retainers; the retainers provided with the cylinder rollers are arranged between the housing washers and the shaft washers; and three rows of thrust bearings are formed by the three housing washers, the three shaft washers and the three retainers. The three housing washers are respectively connected with one another through the outer ring spacer, and the three shaft washers are respectively connected with one another through the inner ring spacer. The three-layer thrust cylinder roller bearing has a compact structure, can bear ultrahigh two-way axial load, can greatly reduce the sizes of a matched shaft and a shaft shell hole, and is applicable to be used in a low-speed large-load part.
Description
Technical field
The utility model relates to bearing, particularly relates to three layers of cylindrical roller thrust bearing.
Background technique
The bearing of traditional accurate extrusion machinery, former employing single row roller bearing, but bearing capacity deficiency influence complete machine working life, if use than big-diameter bearing but insufficient space.
The model utility content
The technical problems to be solved in the utility model provides and a kind ofly can bear superelevation bi-directional axial load, significantly reduce to match axle and axle housing hole dimension, three layers of cylindrical roller thrust bearing of compact structure.
The technological scheme that adopts is:
Three layers of cylindrical roller thrust bearing comprise three seat rings, three blowout patches, three retainers, cylindrical roller, outer ring spacer, cone spacer.The working surface of described three seat rings and three blowout patches is planar surface, three retainers all adopt special-shaped solid cage, all lay many row cylinder rollers on the retainer, the retainer that cylindrical roller is housed is located between seat ring and the blowout patche, forms three row's thrust-bearings by three seat rings, three blowout patches and three retainers.Interconnect by outer ring spacer respectively between three seat rings, interconnect by cone spacer respectively between three blowout patches, constitute three layers of cylindrical roller thrust bearing.
The good effect that the utility model is obtained is:
1, the working surface of the seat ring of this bearing and blowout patche is planar surface, is easy to ensure high rotating accuracy.
2, bearing adopts the bunchiness pairing to use, and ensures that by adjusting cone spacer and outer ring spacer every row bearing is simultaneously stressed, reaches the function of average dispersion applied load.
3, this bearing adopts special-shaped solid cage, and satisfying increases rolling element quantity in maximum space.
4, this bearing structure compactness can be born superelevation bi-directional axial load, and can significantly reduce to match axle and axle housing hole dimension be adapted at the low-speed heave-load position and use.
