Abstract
The utility model discloses a four-row roller bearing which is used for a rolling mill, which represents four-row structured and comprises two couples of the same double-row roller bearings which are juxtaposed. Each double-row roller bearing comprises an outer ring (1), an inner ring (2), double-row rollers (4) and a retainer. A ring diaphragm (7) is arranged between two outer rings (1). A baffle (8) is arranged on the outside of two couples of double-row roller bearings respectively. A through-hole is opened in each roller (4) along the middle axle. Each row of roller is limited in a sleeve of the retainer which comprises a pin shaft (6) for piercing the through-hole and pads (3) and (5) which are fixed by the pin shaft (6) on two sides of the roller. The four-row roller bearing which is used for the rolling mill of the utility model has the advantages of low cost, long use life and strong practicability.
Description
Technical field
The utility model relates to a kind of bearing, more particularly, relates to a kind of four-line column roller bearing.
Background technique
Current domestic large-sized rolling mills bearing generally adopts comb type retainer or rivet retainer, and not only manufacture cost height, and lasso and material that rolling element adopts are GCr15SiMn, in the real-world operation operating mode rating life shorter, bearing very easily is damaged.
Summary of the invention
At the problems referred to above, the utility model provides a kind of four-line column roller bearing that is mainly used in industries such as milling train, metallurgy, have not fragile, the characteristics that the life-span is long.
In order to achieve the above object, the utility model has been constructed a kind of four-row cylindrical roller bearing for rolling mill, is four array structures, by two pairs of identical Biserial cylindrical roller bearings and put and constitute.Each Biserial cylindrical roller bearing is made of foreign country, inner ring, double-row cylindrical roller and retainer.Be provided with spacer ring in the annular between the foreign country of two pairs of Biserial cylindrical roller bearings; The outside of two pairs of Biserial cylindrical roller bearings is respectively arranged with the side bumper circle.Each cylindrical roller offers through hole along axis, and every line column roller is defined in the cover retainer; Every cover retainer comprises the bearing pin that runs through through hole on each roller, and is positioned at every line column roller both sides by the fixing packing ring of bearing pin.
The utility model four-row cylindrical roller bearing for rolling mill, its improvement are that the bearing pin two ends are stepped, and end radius is less than the middle part radius; The pin-and-hole of packing ring is a unthreaded hole, is connected with the cold riveting form with bearing pin.
In addition, the foreign country middle part is provided with bulge loop.Bulge loop, middle spacer ring and side bumper circle define the axial position of every line column roller.Foreign country and middle spacer ring are provided with lubrication hole.
By technique scheme, four-row cylindrical roller bearing for rolling mill of the present utility model has that cost is low, long service life, practical characteristics.

Embodiment
Shown in Fig. 1-8, a kind of four-row cylindrical roller bearing for rolling mill of the utility model is made up of foreign country 1, inner ring 2 and first packing ring 3, second packing ring 5, cylindrical roller 4, bearing pin 6, middle spacer ring 7 and side bumper circle 8.Roller 4 is arranged among the pocket hole that first packing ring 3 and second packing ring 5 constituted, and roller 4 is a hollow roller; Pack into the pocket hole bottom of roller 4 is drilled with and the identical unthreaded hole of roller 4 quantity, is connected with second packing ring 5 with first packing ring 3 by bearing pin 6.Wherein, the two ends that packing ring is connected with bearing pin connect by the cold riveting form, thereby make first packing ring 3, roller 4 and second packing ring 5 form one.
Inside and outside lasso of the utility model four-row cylindrical roller roller-mill bearing and rolling element material are GCr15SiMn, and the short pawl of retainer carries unthreaded hole, and rolling element is with holes.
Among the figure, bearing is four array structures, by two pairs of identical Biserial cylindrical roller bearings and put and constitute; Each Biserial cylindrical roller bearing is made of foreign country 1, inner ring 2, double-row cylindrical roller 4 and retainer.Be provided with spacer ring 7 in the annular between two pairs of foreign countries 1; The outside of two pairs of Biserial cylindrical roller bearings is respectively arranged with side bumper circle 8.Each cylindrical roller 4 offers through hole along axis.Every line column roller is defined in the cover retainer, and every cover retainer comprises the bearing pin 6 that runs through each through hole, and is positioned at the packing ring 3 and 5 that every line column roller both sides are fixed by bearing pin 6.Under the optimal way, bearing pin 6 two ends are stepped, and end radius is less than the middle part radius; Packing ring 3 and 5 pin-and-hole are unthreaded hole, are connected with the cold riveting form with bearing pin 6.In addition, foreign 1 middle part is provided with bulge loop 101.Bulge loop 101, middle spacer ring 7 and side bumper circle 8 define the axial position of every line column roller 4.Foreign country 1 and middle spacer ring 7 are provided with lubrication hole.
