Abstract
The utility model discloses a novel four-row tapered roller bearing. The four-row tapered roller bearing comprises a double outer ring, single outer rings, holding racks, an inner ring spacer ring, outer ring spacer rings, tapered rollers, inner rings and inner holes, wherein the double outer ring is arranged in the middle position of the bearing, the two single outer rings are arranged on two sides of the bearing, the outer ring spacer ring is arranged between each single outer ring and the double outer ring respectively, the bearing is provided with two inner rings, and the inner ring spacer ring is arranged between the two inner rings; the tapered rollers are arranged between the inner rings and the double outer ring, and between the inner rings and the single outer rings, and are fixed through the holding racks, and inner holes are formed in the inner rings. The hardening process is performed to the inner ring spacer ring, and the surfaces of the inner holes are processed to take the shapes of spiral lines.
Description
Technical field
The utility model relates to technical field of bearings, concrete relates to the novel four-row tapered roller bearing on the low speed milling train in a kind of being applicable to.
Background technique
Four-row tapered roller bearing is one of main rolling bearing, and the radial and axial load-carrying ability of this class bearing is all bigger, can bear bigger bi-directional axial load, but limit speed is lower, the supporting of thick in mainly being used as (steel) plate mill back-up roll.Traditional supporting roller bearing, when taking transition fit or Spielpassung to install between roller neck and the bearing bore diameter, greasy dirt in the slit and minute impurities can make roll neck and bearing bore diameter surface friction, thereby produce wearing and tearing.
Summary of the invention
In view of the defective that existing procucts exist, the purpose of this utility model is that the novel four-row tapered roller bearing on the low speed milling train in a kind of being applicable to will be provided.
For achieving the above object, the technical solution that the utility model adopted mainly is made up of two outer rings, single outer ring, retainer, inner ring spacer ring, outer ring spacer ring, tapered roller, inner ring and endoporus.Described pair of outer ring is in the neutral position of this bearing, and there is an outer ring spacer ring two single outer rings in these bearing both sides between single outer ring and the two outer ring; This bearing has two inner rings, and an inner ring spacer ring is arranged between two inner rings; Between inner ring and two outer ring, the single outer ring tapered roller is set, described tapered roller is fixed by retainer, and the inner ring the inside is an endoporus.
Described inner ring spacer ring is through cure process.
Described bore area is processed into spiral yarn shaped.
Because the inner ring spacer ring of this bearing process cure process, thereby make surface abrasion reduce to minimum.Bore area is processed into spiral yarn shaped, and greasy dirt in the slit and minute impurities can be discharged from helix, alleviates roll neck and bearing bore diameter surface abrasion, so that the suitable complex environment of bearing and prolong bearing working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Fig. 1 reference character is as follows: two outer rings 1, single outer ring 2, retainer 3, inner ring spacer ring 4, outer ring spacer ring 5, tapered roller 6, inner ring 7, endoporus 8.
In novel four-row tapered roller bearing schematic representation shown in Figure 1, its main structure comprises two outer rings 1, single outer ring 2, retainer 3, inner ring spacer ring 4, outer ring spacer ring 5, tapered roller 6, inner ring 7 and endoporus 8 compositions.Described pair of outer ring 1 is in the neutral position of this bearing, and there is an outer ring spacer ring 5 two single outer rings 2 in these bearing both sides between single outer ring 2 and the two outer ring 1; This bearing has between 7, two inner rings 7 of two inner rings an inner ring spacer ring 4 is arranged; Between inner ring 7 and two outer ring 1, the single outer ring 2 tapered roller 6 is set, described tapered roller 6 is fixing by retainer 3, and inner ring 7 the insides are endoporus 8.
