Abstract
The invention relates to a four-row cylindrical roller bearing for a rolling mill. Two freely rotatable rollers are clamped between two adjacent pillars in a bearing retainer. End faces of the rollers are equipped with inward concave oil storage grooves, and the edges of the pillars are provided with oil-passing grooves. A curved surface fitting the rollers is formed on one pillar side facing the rollers. The curved surface bottom of each pillar is axially provided with lubrication grooves communicated with the oil-passing grooves. A bearing outer ring, a bearing outer ring, the retainer, and the rollers are all made of a steel material. The middle retaining ring in an original bearing outer ring is abolished in the bearing, and is changed into a rolling body bearing area, the rollers are lengthened, the dynamic load of the bearing is enhanced by about 15%, and the service life is effectively improved. The adopted steel retainer has the advantages of light weight, high strength and good lubrication, thus being suitable for an expanded bearing use surface that is at a high rotation speed and does not deform in a high temperature environment.
Description
Technical field
The present invention relates to technical field of bearings, especially a kind of four-row cylindrical roller bearing for rolling mill.
Background technique
Nowadays the normal four-line column roller bearing that uses with comb type copper cage of people in steel rolling is produced, this bearing is under the condition of normal operation, bearing radial load satisfies the rolling using effect that requires fully can be fine, but the grinding undercut that bearing outer ring arranges is more, bearing load is less, retainer intensity is lower, and lubricating status is bad.
When this class bearing is larger in rolling load, impact load is larger, and when speed was higher, the damage of bearings rate increased thereupon, brought larger economic loss to steel mill.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, a kind of four-row cylindrical roller bearing for rolling mill is provided, solve bearing when the steel of rolling ask for something, the shortcoming that bearing intensity is low, lubrication effect is poor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of four-row cylindrical roller bearing for rolling mill, by two identical retainer juxtapositions on bearing inner race, two retainers all are provided with corresponding bearing outer ring, be provided with middle ring washer between two bearing outer rings, the outer side of two bearing outer rings is provided with the both sides back-up ring, in the retainer between adjacent two pillars clamping roller free to rotate is arranged, the quantity of the roller of clamping is 2 between described two pillars, the oil storage tank that has indent on the roller both ends of the surface was provided with oil groove on the seamed edge of pillar.Oil storage tank can effectively be stored the lubricant oil of annotating in the bearing, makes roller end face remain lubricated, prolongs roller working life.
Furtherly, described pillar is formed with the curved surface suitable with roller towards the one side of roller, and the curved bottom portion of pillar axially offers the lubrication groove that communicates with the mistake oil groove.The design of crossing oil groove makes things convenient for lubricant oil to contact with roller, and lubrication groove is provided, and prolongs the lubrication time of roller.
Furtherly, described two bearing outer rings offer the lubrication hole for charging-up lubricant oil.
Furtherly, described bearing outer ring, bearing inner race, retainer and roller all adopt steel material to make.
The invention has the beneficial effects as follows: the invention provides a kind of four-row cylindrical roller bearing for rolling mill, this bearing changes the middle-grade limit cancellation of former bearing outer ring into the rolling element bearing area, and roller lengthens, and improves bearing movable load about 15%, and the life-span effectively improves; Designed oil groove on the cage pin, and made bearing lubrication more abundant, the bearing oil content is higher, can deposit lubricant grease 10% more; Adopt the steel retainer, lightweight, intensity is high, lubricates, and is applicable to high rotating speed, can be indeformable under hot environment, and the use face of the bearing of expansion.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 be bearing partly cut open schematic diagram;
Fig. 2 is the structural representation of retainer.
Fig. 3 is the structural representation of A-A among Fig. 2.
Fig. 4 is the layout enlarged view at B place among Fig. 2.
Fig. 5 is the structural representation of roller.
Wherein: 1, roller, 1-1, oil storage tank, 2, pillar, 2-1, lubrication groove, are crossed oil groove at 2-2, and 3, bearing inner race, 4, bearing outer ring, 4-1, lubrication hole, 5, the side bumper circle, 8, middle ring washer.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Such as Fig. 1 such as Fig. 2 Fig. 3 Fig. 4 a kind of four-row cylindrical roller bearing for rolling mill shown in Figure 5, by two identical retainer juxtapositions on bearing inner race 3, two retainers all are provided with corresponding bearing outer ring 4, be provided with middle ring washer 8 between two bearing outer rings 4, the outer side of two bearing outer rings 4 is provided with 5, two bearing outer rings 4 of both sides back-up ring and offers lubrication hole 4-1 for charging-up lubricant oil;
In the retainer between adjacent two pillars 2 clamping the quantity of the roller 1 of clamping between roller free to rotate 1, two pillar 2 is arranged is 2, have the oil storage tank 1-1 of indent on roller 1 both ends of the surface; Oil storage tank 1-1 can effectively store the lubricant oil of annotating in the bearing, makes roller 1 end face remain lubricated, prolongs 1 working life of roller.
Bearing outer ring 4, bearing inner race 3, retainer and roller 1 all adopt steel material to make.
The present invention has cancelled the middle-grade limit of bearing outer ring 4, changes the zone on original middle-grade limit into the rolling element bearing area, and roller 1 just can become longer like this, improves bearing movable load about 15%, and the life-span effectively improves; Designed oil groove 2-2 on the cage pin 2, and made bearing lubrication more abundant, the bearing oil content is higher, can deposit lubricant grease 10% more; Adopt the steel retainer, lightweight, intensity is high, lubricates, and is applicable to high rotating speed, can be indeformable under hot environment, and the use face of the bearing of expansion.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
