Abstract
The utility model belongs to the bearing technical field and relates to a double row cylindrical roller bearing for rolling mill, consisting of an outer ring, an inner ring, a cage seat, a cage cover, rollers and a rivet, wherein, the cage seat is placed between the outer ring and the inner ring; the rollers are put into the cage seat; the cage cover and the cage seat are connected through the rivet; the end face of the inner ring is provided with a side retaining ring. The utility model has the advantages that: the radial load and the axial load of the bearing are separately borne; the radial load is borne by a raceway; the axial load is borne by a retaining side; the life-span is improved by more than ten times as no offset load exists.
Description
Technical field
The utility model belongs to technical field of bearings, relates to a kind of rolling mill double-row cylinder roller bearing, is mainly used in industries such as milling train, electromechanics, metallurgy.
Background technique
The inside and outside circle raceway of selfaligning roller bearing not only bears radial load but also bear axial load, if when axial load surpasses usage requirement, causes a row overload, a row unloading, although so not serious, also can cause unbalance loading, quickened the fatigue ruption of a row bearing.
Former back-up roll and the work roll hot and cold milling train of aligning roller, the bearing life weak point is long-standing.
Summary of the invention
The purpose of this utility model is to propose a kind of rolling mill double-row cylinder roller bearing, and its inner ring two ends and be provided with the side bumper circle and need cut a hole on the external diameter of retainer and print lock ball just can prevent that steel ball from dropping out from external diameter.
The technical solution of the utility model is, a kind of Biserial cylindrical roller bearing for rolling mill, form by outer ring 1, inner ring 2, maintenance stand 3, retainer lid 5, roller 4 and rivet 7, keep stand 3 to place between outer ring 1 and the inner ring 2, roller 4 is packed into and is kept in the stand 3, retainer lid 5 is connected by rivet 7 with keeping stand 3, and the inner ring end face is provided with side bumper circle 6.
The beneficial effects of the utility model are, this bearing radially separates with axial load and bears: radial load is born by raceway; Axial load is born by rib, does not have the unbalance loading problem, so exceed working life more than 10 times.
Description of drawings
Fig. 1 is that milling train of the present utility model assembles schematic representation with the double-row cylindrical roller structure.
Among the figure, 1, the outer ring, 2, the outer ring, 3, keep stand, 4, roller, 5, the retainer lid, 6, the side bumper circle, 7, rivet.
Embodiment
As accompanying drawing 1, the utility model is made up of outer ring 1, inner ring 2, maintenance stand 3, retainer lid 5, roller 4 and rivet 7, keep stand 3 to place between outer ring 1 and the inner ring 2, roller 4 is packed into and is kept in the stand 3, retainer lid 5 is connected by rivet 7 with keeping stand 3, and the inner ring end face is provided with side bumper circle 6.Because inner ring 2 both ends of the surface have added side bumper circle 6, make bearing bear bi-directional axial load.Improved bearing life.
