Abstract
The utility model relates to a reinforced four-row cylindrical roller bearing, which comprises a bearing inner ring, two bearing retainers and a bearing outer ring, wherein the bearing inner ring is sleeved with the two bearing retainers; and the two bearing retainers are sleeved with the bearing outer ring. Riveting heads connected with edge check rings are arranged at two ends of a strut respectively; the section of each riveting head is oval, the riveting heads are longer than riveting holes, and the riveting heads are in interference fit with the riveting holes on the edge check rings; a curved surface matched with a roller is formed on a side face of the strut towards the roller; an oil groove is formed at an edge of the strut; and a lubrication groove which is communicated with the oil groove is axially formed at the bottom of the curved surface of the strut. The riveting heads of the strut in the bearing retainer are longer than the riveting holes and are in interference fit with the riveting holes, and the section of each riveting head is oval, so that the riveting heads are not easy to slip out of the riveting holes of the edge check rings, so as to improve the stability of the bearing retainer.
Description
Technical field
The utility model relates to a kind of enhanced four-row cylindrical roller bearing.
Background technique
Nowadays people often use the four-line column roller bearing that has comb type copper cage in steel rolling is produced; This bearing is under the condition of proper functioning; Bearing radial load satisfies the rolling using effect that requires fully can be fine, but the grinding undercut that bearing outer ring is provided with is more, and bearing load is less; Retainer intensity is lower, and lubricating status is bad.
When this class bearing is bigger in rolling load, impact load is bigger, and when speed was higher, the damage of bearings rate increased thereupon, brought bigger economic loss to steel mill.
The model utility content
The technical problem that the utility model will solve is: overcome the deficiency of existing technology, a kind of enhanced four-row cylindrical roller bearing is provided, solve retainer structural instability in the bearing, lubricated inadequate shortcoming.
The utility model solves the technological scheme that its technical problem adopted: a kind of enhanced four-row cylindrical roller bearing; Comprise bearing inner race, be socketed in two retainers and the bearing outer ring of two retainers of socket on the bearing inner race; The bearing outer ring both sides are provided with loose rib; Described retainer connects two side bumper circles by pillar and forms column structure, and the pillar two ends are the die of fillet back-up ring, and the rivet hole on die and the side bumper circle is an interference fit; Be formed for the pocket hole of clamp axis bearing roller between adjacent two pillars, be placed with two bearing rollers free to rotate in each pocket hole.
Furtherly, described pillar is formed with the curved surface suitable with roller towards the side of roller, and the seamed edge of described pillar was provided with oil groove, and the curved bottom portion of pillar axially offers and crosses the lubrication groove that oil groove communicates.
Furtherly, the length of described die is greater than the length of rivet hole.Die length is greater than the length of rivet hole, and pillar is after fixing like this, and die just has one section and stretches out outside rivet hole, and pillar just is not easy from rivet hole slippage and comes out like this, makes the stability of retainer higher.
Furtherly, described die cross section is oval.Ellipsoidal structure can make that pillar is difficult for rotating, and improves the stability of retainer.
Furtherly, said bearing outer ring offers the lubrication hole of the lubricant oil that is used to annotate.
Furtherly, described bearing outer ring, bearing inner race, retainer and roller all adopt steel material to process.Adopt steel material, can make bearing in light weight, 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.
The beneficial effect of the utility model is: the utility model provides a kind of enhanced four-row cylindrical roller bearing; Through the length of the pillar die in the retainer is arranged to greater than rivet hole length; It between die and the rivet hole interference fit; And the sectional shape of die is designed to ellipse, makes die be not easy from the rivet hole of side bumper circle slippage like this and comes out, and improves the stability of retainer; Bearing outer ring, bearing inner race, retainer and roller all adopt steel material to process, and can make bearing in light weight, and 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.

Embodiment
Combine accompanying drawing that the utility model is further described now.The schematic representation that these accompanying drawings are simplification is only explained the basic structure of the utility model in a schematic way, so it only shows the formation relevant with the utility model.
Shown in Figure 4 like Fig. 1 Fig. 2 Fig. 3; A kind of enhanced four-row cylindrical roller bearing; Comprise bearing inner race 1, be socketed in two retainers 2 and the bearing outer ring 3 of two retainers 2 of socket on the bearing inner race 1; Bearing outer ring 3 both sides are provided with loose rib; Retainer 2 connects two side bumper circles 25 by pillar 21 and forms column structure, and bearing outer ring 3 offers the lubrication hole 31 of the lubricant oil that is used to annotate, and bearing outer ring 3, bearing inner race 1, retainer 2 and roller all adopt steel material to process.
Be formed for the pocket hole of clamp axis bearing roller between adjacent two pillars 21; Be placed with two bearing rollers free to rotate in each pocket hole; Pillar 21 is formed with the curved surface suitable with roller towards the side of roller; The seamed edge of pillar 21 was provided with oil groove 23, and the curved bottom portion of pillar 21 axially offers and crosses the lubrication groove 24 that oil groove 23 communicates.
Die 22 length on retainer 2 B-C posts 21 are arranged to greater than rivet hole length; It between die 22 and the rivet hole interference fit; And the sectional shape of die 22 is designed to ellipse; Make die 22 be not easy from the rivet hole of side bumper circle 25 slippage like this and come out, improve the stability of retainer 2; Bearing outer ring 3, bearing inner race 1, retainer 2 and roller all adopt steel material to process, and can make bearing in light weight, and 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; Oil groove 23 and lubrication groove 24 were set on the pillar 21 of retainer 2, make bearing lubrication more abundant, the bearing oil content is higher, can deposit lubricant grease 10% more.
