Abstract
The utility model discloses a four-row tapered roller bearing without spacer, which mainly comprises an outer ring, a second outer ring, an inner ring, a retainer and tapered rollers; both external sides of the bearing are respectively provided with two single-raceway outer rings and a double-raceway second outer ring disposed there between; and two inner sides are respectively provided two double-raceway inner rings; the tapered rollers are disposed between the inner ring, outer ring and second outer ring on each side; and all the tapered rollers are fixed by the retainer. Wherein the inner ring bore surface is designed into spiral shape. The utility model achieves the advantages of convenient installation, adjustable windage and high bearing capacity; and can improve the operation quality of rolling mill.
Description
Technical field
The utility model relates to technical field of bearings, concrete relates to a kind of cageless four-row tapered roller bearing that is used for rolling mill.
Background technology
Four-row tapered roller bearing is when bearing bigger radial load, can bear the axial load of both direction simultaneously, in general in bearing configuration, do not need other thrust bearing, successfully use steel rolling speed as low speed to the roll of the working roll of the rolling mill of middling speed and blooming mill.Because the design of four-row tapered roller bearing, this bearing must be installed on the roll chock as complete bearing, and in order to change roll fast, this bearing must loose fit on roll pins having.The shortcoming of loose fit is that inner ring is being wriggled on its pedestal under the main load-up condition; usually can cause the wearing and tearing of the pedestal that the hardness ratio race ring is low; and when taking interference fits or matched in clearance to install between roller neck and the bearing bore diameter; greasy dirt in the slit and minute impurities have been accelerated the rate of wear on roll neck and bearing bore diameter surface, influence the running quality of milling train.
Summary of the invention
In view of the defective that prior art exists, the purpose of this utility model is to provide a kind of easy to assembly, and bearing capacity is strong, and can reduce the cageless four-row tapered roller bearing of wearing and tearing.
For achieving the above object, the technical solution that the utility model adopted mainly comprises outer ring, second outer ring, inner ring, retainer and taper roller.This bearing both sides external is two single raceway outer rings and two raceway second outer ring between it, and there are two two raceway inner rings inner both sides, between inner ring and outer ring and second outer ring taper roller are set, and each taper roller is fixed by retainer.Described inner ring bore area is designed to helix shape.
The utility model has the advantages that: 1, compare, cancelled outer ring spacer and cone spacer, reduced bearing parts with band spacer ring bearing, simplified installation procedure, and in the long-term use, after play strengthens, can grind bearing face, to reach the purpose of adjusting play; 2, the rolling element size that can extend has improved bearing load carrying capacity; 3, the bearing inner race bore area has increased helix, when taking interference fits or matched in clearance to install between roller neck and the bearing bore diameter, greasy dirt in the slit and minute impurities can be discharged from helix, alleviate roll neck and bearing bore diameter surface abrasion, improve the milling train running quality.
The utility model installation is convenient, and play is adjustable, has high bearing capacity and can improve the milling train running quality.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Fig. 1 Reference numeral is as follows: second outer ring 1, outer ring 2, retainer 3, taper roller 4, inner ring 5.
In cageless four-row tapered roller bearing schematic diagram shown in Figure 1, its primary structure comprises outer ring 2, second outer ring 1, inner ring 5, retainer 3 and taper roller 4.This bearing both sides external is two single raceway outer rings 2 and two raceway second outer ring 1 between it, and there are two two raceway inner rings 5 inner both sides, and inner ring 5 and outer ring 2 and 1 of second outer ring are provided with taper roller 4, and each taper roller 4 is fixing by retainer 3.
Claims (2)
1. cageless four-row tapered roller bearing is characterized in that: mainly comprise outer ring, second outer ring, inner ring, retainer and taper roller; This bearing both sides external is two single raceway outer rings and two raceway second outer ring between it, and there are two two raceway inner rings inner both sides, between inner ring and outer ring and second outer ring taper roller are set, and each taper roller is fixed by retainer.
2. according to claim 1 described cageless four-row tapered roller bearing, it is characterized in that: described inner ring bore area is designed to helix shape.
