Abstract
The utility model is mainly applied in steel industry, and relates to a self-pretightening double-row tapered roller bearing used on the roller of a rolling mill. The bearing comprises two single-rolling path outer rings, an inner ring, setup springs, a retainer and a roller, wherein, eight to sixteen setup springs are mounted in grooves on two end surfaces of each outer ring; the retainer, the roller and the inner ring from a double row tapered inner component; the double row tapered inner component and the single-rolling path outer ring form a complete bearing; and the inner ring is provided with an inclined key slot for positioning. The utility model has the benefits that not only can the axial load requirements be met, but also the problems of low clearance control probability, bearing inner ring creepage, short service life and high temperature rise are effectively solved.
Description
Technical field
The utility model relates to a kind of steel industry that is mainly used in, and is used in the self-pretightening double-row tapered roller bearing on the rolling mill roll.
Background technique
Traditional roller-mill bearing was the normal configuration double-row conical bearing originally, bore thrust load.Because these bearing structure characteristics, bearing are in installation process, dress back play can only rely on the operator rule of thumb to adjust, and very wayward, the excessive or too small bearing that all can cause damages in advance.
The model utility content
Bearing dress back play is wayward, bearing inner race is wriggled, working life is low, the problem of temperature rise in order to overcome, and the utility model provides a kind of self-pretightening double-row tapered roller bearing.
The technical solution of the utility model is: a kind of self-pretightening double-row tapered roller bearing, comprise two single raceway outer rings 2, inner ring 5, loaded spring 1, retainer 3 and a roller 4,8～16 loaded springs 1 respectively are installed in the groove of outer ring 2 both ends of the surface, retainer 3, roller 4 and inner ring 5 are formed biserial circular cone inner assembly, complete bearing is formed in biserial circular cone inner assembly and single raceway outer ring 2, and wherein inner ring 5 has the taper key groove and positions structure.
The beneficial effects of the utility model are: not only well satisfy the thrust load requirement, and solved effectively that play is wayward, bearing inner race wriggling, working life are low, the problem of temperature rise.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, loaded spring, 2, the outer ring, 3, retainer, 4, roller, 5, inner ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, a kind of self-pretightening double-row tapered roller bearing, comprise two single raceway outer rings 2, inner ring 5, loaded spring 1, retainer 3 and a roller 4,12 loaded springs 1 respectively are installed in the groove of outer ring 2 both ends of the surface, retainer 3, roller 4 and inner ring 5 are formed biserial circular cone inner assembly, complete bearing is formed in biserial circular cone inner assembly and single raceway outer ring 2, and wherein inner ring 5 has the taper key groove and positions structure.
