Abstract
The invention provides a rolling mill working roller thrust bearing which is manly applied to iron and steel industry and is used for the two ends of a Sendzimir rolling mill working roller. The rolling mill working roller thrust bearing is composed of a bearing outer ring, an inner ring, a retainer, a rolling body and a flat retainer ring, wherein the rolling body is a single-row cylindrical roller; the retainer is of a single-claw retainer structure; the inner ring is a single-flange inner ring; and the flat retainer ring is arranged on one flange-free side of the inner ring to form an open type structure. The single-row cylindrical roller and the single-claw retainer structure are adopted so that the machining difficulty of the retainer is lowered; the retainer adopts the special structure and a special relation between the retainer and an inner ring flange is utilized so that the axial and radial positioning effects of the retainer are realized; and the rolling mill working roller thrust bearing can be operated stably under the effects of high-speed rotation and impact loads. The inner ring adopts a single-flange structure so that the axial and radial positioning of the retainer can be realized and the retainer is convenient to mount; and the radial thickness of the retainer is increased and the strength of the retainer is enhanced.
Description
Technical field
The present invention relates to thrust bearing of rolling mill working roller, be mainly used in steel industry, be used in sendzimir mill work roll two ends.
Background technique
The former full-complement cylinder roller bearing adopting band back-up ring of high rotating speed sendzimir mill supporting roller bearing, mainly bears radial impact load, high to rotation speed requirements.Due to bearing structure feature, full-complement cylinder roller bearing rotating speed is lower, there is retaining ring sealing both sides, and lubricating condition is poor, often occur anxious acceleration or anxious situation of slowing down in using, during bearing high speed rotating, temperature rise is higher, and bearing and axle adopt transition fit, often there is relative movement in inner ring internal diameter and axle in running, causes the temperature of bearing to raise, often there is the cracked and phenomenon of " locking " in outer ring in bearing, working life is shorter.And because sendzimir mill requires relatively little again compared with Gao Erqi bearing herein to bearing accuracy, Product Precision does not reach requirement.
Summary of the invention
In order to solve above-mentioned prior art Problems existing, the invention provides a kind of high rotating speed sendzimir mill work roll thrust bearing
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is thrust bearing of rolling mill working roller, is made up of bearing outer ring, inner ring, retainer, rolling element and loose rib; Rolling element is single-row cylinder roller; Retainer is monodactyle retainer structure; Inner ring is single block border inner ring, and loose rib is arranged on inner ring without rib side, composition Open architecture.Described inner ring peripheral wall arranges several oilholes, and oilhole is through hole.Described retainer comprises the section of grabbing and connecting ring section, and connecting ring section is arranged in the fluted body space that surrounded by bearing outer ring and single block border side.
The concrete numerical value such as the impulsive load of bearing according to bearing and working speed, calculate by analysis, select the technological scheme that best, bearing structure, choose most suitable main parameter, comprise a single raceway outer ring thickeied, a single block border inner ring, loose rib, a monodactyle retainer and rolling element diameter, length, a quantity.Wherein rolling element is put into bearing outer ring and is evenly separated, then retainer is put into bearing outer ring, and rolling element is evenly separated, then put into inner ring from the same side, finally putting into loose rib by opposite side forms a set of complete bearing.
After adopting such scheme, compared with prior art there is following beneficial effect: adopt single-row cylinder roller and monodactyle retainer structure, reduce the difficulty of processing of retainer, retainer takes special structure, utilize the special relationship between itself and inner ring rib, reach the effect of retainer axis and the two-way location of radial direction, can smooth operation under High Rotation Speed and impact loading.Inner ring adopts single block border structure, not only can provide retainer axis and radial location, make retainer easier for installation, also make the radial thickness of retainer increase to some extent, strengthen the intensity of retainer.Have hole number and the single block border inner ring that add inner ring add the Open architecture of back-up ring, add the lubrication effect of oiling agent largely, solve the problems such as bearing bore diameter wearing and tearing, bearing locking, life-span be short well.
Accompanying drawing explanation
Fig. 1 is the structural drawing of thrust bearing of rolling mill working roller;
In figure: 1, bearing outer ring, 2, inner ring, 3, retainer, 4, rolling element, 5, loose rib, 3.1, the section of grabbing, 3.2, connecting ring section.
Embodiment
For understanding the structure of thrust bearing of rolling mill working roller in depth, composition graphs 1 is described as follows: thrust bearing of rolling mill working roller, is made up of bearing outer ring 1, inner ring 2, retainer 3, rolling element 4 and loose rib 5; Rolling element 4 is single-row cylinder roller; Retainer 3 is monodactyle retainer structure; Inner ring 2 is single block border inner ring, and loose rib 5 is arranged on inner ring 2 without rib side, composition Open architecture.Inner ring 2 peripheral wall arranges several oilholes, and oilhole is through hole.Retainer 3 comprises the section of grabbing 3.1 and connecting ring section 3.2, and connecting ring section 3.2 is arranged in the fluted body space that surrounded by bearing outer ring 1 and single block border side.
The concrete numerical value such as the impulsive load of bearing according to bearing and working speed, calculate by analysis, select the technological scheme that best, bearing structure, choose most suitable main parameter, comprise a single raceway outer ring thickeied, a single block border inner ring, loose rib, a monodactyle retainer and rolling element diameter, length, a quantity.Wherein rolling element 4 is put into bearing outer ring 1 and is evenly separated, then retainer 3 is put into bearing outer ring 1, and rolling element 4 is evenly separated, then put into inner ring 2 from the same side, finally putting into loose rib 5 by opposite side forms a set of complete bearing.
Adopt single-row cylinder roller and monodactyle retainer structure, reduce the difficulty of processing of retainer, retainer takes special structure, utilize the special relationship between itself and inner ring rib, reach the effect of retainer axis and the two-way location of radial direction, can smooth operation under High Rotation Speed and impact loading.Inner ring adopts single block border structure, not only can provide retainer axis and radial location, make retainer easier for installation, also make the radial thickness of retainer increase to some extent, strengthen the intensity of retainer.Have hole number and the single block border inner ring that add inner ring add the Open architecture of back-up ring, add the lubrication effect of oiling agent largely, solve the problems such as bearing bore diameter wearing and tearing, bearing locking, life-span be short well.High rotating speed sendzimir mill work roll thrust bearing, not only well meets rotating speed and loading demands, outer ring is cracked, bore wear, bearing burnt, the life-span is short, precision is low etc., and problem also obviously reduces.
