Abstract
The utility model discloses a four-row roller bearing which is used for a rolling mill without eccentric load, which comprises double outer rings (1), an inner ring (2), two groups of retainers (6) between outer rings (1) and the inner ring (2). Two rows of roller are arranged on each retainer (6) along the circumferential direction. The four-row roller bearing which is used for the rolling mill without eccentric load is characterized in that a side retainer (11) is arranged on two end faces of outer rings (1), which makes the radial load and the axial load of the bearing bear respectively and doesn't generate bias carry. Thereby that the length of two rows of roller are increased, which makes the tray contact area increase and the radial load bearing force increase correspondingly, thereby lengthening the use life.
Description
Technical field:
The utility model relates to the four-line column roller bearing of sector applications such as a kind of milling train, electromechanics, metallurgy, the load-bias free four row roller bearing for rolling mill that especially a kind of durable, working life is long.
Background technique:
At present, the selfaligning roller bearing of sector applications such as milling train, its inside and outside state raceway promptly bears radial load and bears axial load again, in case when surpassing usage requirement, will cause a row overload, a row unloading, although not serious so, also can cause unbalance loading, quicken the fatigue ruption of a row bearing.Therefore the back-up roll of former hot and cold milling train and work roll are shorter with the selfaligning roller bearing life-span, and the later maintenance expense is higher.
Summary of the invention:
The utility model provides a kind of and can reduce unbalance loading at the above-mentioned deficiency of existing in prior technology, the load-bias free four row roller bearing for rolling mill that working life is long.
Technical solution of the present utility model is: a kind of load-bias free four row roller bearing for rolling mill, be provided with two foreign countries and inner ring, between foreign country and inner ring, be provided with two groups of retainers, along the circumferential direction uniform two line column rollers that are equipped with on each retainer, it is characterized in that: foreign both ends of the surface are provided with the side bumper circle.The side bumper circle can bear axial load.
The length of the columna roller in described each retainer is than the length long 1/4-1/2 of another line column roller.
The utility model adds the side bumper circle in foreign both ends of the surface, the bearing radial load is separated with axial load bear, and does not have unbalance loading, and increased the wherein length of two line column rollers, the raceway area of contact is increased, and the corresponding increase of radial load ability to bear has improved working life.

Fig. 2 is the structural representation of the utility model foreign country.
Fig. 3 is the structural representation of the utility model inner ring.
Fig. 4 is the structural representation of the utility model side bumper circle.
Embodiment:
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Shown in Fig. 1 ~ 4, a kind of load-bias free four row roller bearing for rolling mill is provided with two foreign countries 1 and inner ring 2, and foreign 1 both ends of the surface are provided with side bumper circle 11.Be provided with two groups of retainers 6 in foreign country 1 and 2 of inner rings, retainer lid 16 is connected by rivet 9 with retainer 6, along the circumferential direction uniform two line column rollers that are equipped with on each retainer 6, the length of the columna roller 4 in each retainer 6 is than the length long 1/4-1/2 of another line column roller 24.
Claims (2)
1. load-bias free four row roller bearing for rolling mill, be provided with two outer rings (1) and inner ring (2), between outer ring (1) and inner ring (2), be provided with two groups of retainers (6), along the circumferential direction uniform two line column rollers that are equipped with on each retainer (6) is characterized in that: outer ring (1) both ends of the surface are provided with side bumper circle (11).
2. load-bias free four row roller bearing for rolling mill according to claim 1 is characterized in that: the length of the columna roller (4) in described each retainer (6) is than the length long 1/4-1/2 of another line column roller (24).
