Abstract

The present invention relates to steel rolling mills tapered roller bearing, specifically a kind of tapered roller bearing with laminating formula spacer ring is mainly used on steel hot-rolled and cold-rolled machine equipment, to use as thrust bearing of the roll.The bearing includes outer ring, inner ring, rolling element, spacer ring, and the bearing outer ring is structure as a whole with spacer ring, forms inseparable integrated bearing.The laminating formula spacer ring structure of the present invention, spacer ring and outer ring are combined, a kind of overall structure is formed, bearing is facilitated integrally to be fixedly mounted, and realize easy for installation, while being greatly improved to bearing accuracy and service performance, reduction race deformation and abrasion.

Description

Tapered roller bearing with laminating formula spacer ring
Technical field
The present invention relates to steel rolling mills tapered roller bearing, specifically a kind of taper roller axis with laminating formula spacer ring It holds, is mainly used on steel hot-rolled and cold-rolled machine equipment, to be used as thrust bearing of the roll.
Background technique
In field of steel metallurgy, milling train tapered roller bearing is mostly separated type bearing, and this bearing installing and dismounting is cumbersome, If bearing Rig up error also results in the abrasion and deformation of bearing ring, the precision and service life of bearing are influenced.Therefore, it is necessary to Improvement is carried out to such bearing.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of tapered roller bearings with laminating formula spacer ring.
For achieving the above object, the invention adopts the following technical scheme:
A kind of tapered roller bearing with laminating formula spacer ring, the bearing include outer ring, inner ring, rolling element, spacer ring, the axis Bearing outer-ring is structure as a whole with spacer ring, forms inseparable integrated bearing.
A kind of above-mentioned tapered roller bearing with laminating formula spacer ring, spacer ring end face are equipped with fixed keyway, and outer ring is equipped with and hangs Hole is filled, outer ring and spacer ring fixation are integral by fixing screws through fixed keyway and hole for hoist；Spacer ring is equipped with fixing screw hole, outside Circle is equipped with annular groove, and spacer ring is extended on the outer diameter of outer ring and fixed with screw through fixing screw hole and annular groove, right The two-way positioning of outer ring axially and radially.
Compared with prior art, the invention has the benefit that the laminating formula spacer ring structure of the present invention, by spacer ring and outer ring group Be combined, form a kind of overall structure, bearing is facilitated integrally to be fixedly mounted, realize it is easy for installation, while to bearing accuracy It is greatly improved with service performance, reduces race deformation and abrasion.
Detailed description of the invention
Fig. 1 schematic structural view of the invention；
Fig. 2 spacer ring structural schematic diagram of the present invention；
Fig. 3 outer ring structure schematic diagram of the present invention.
Specific embodiment
The present invention will be further described below with reference to the accompanying drawings.
A kind of tapered roller bearing with laminating formula spacer ring, the bearing include outer ring 3, inner ring 5, rolling element 4, spacer ring 1, the bearing outer ring is structure as a whole with spacer ring, forms inseparable integrated bearing；Spacer ring end face is equipped with fixed keyway 7, Outer ring is equipped with hole for hoist 8, and outer ring and spacer ring fixation are integral by fixing screws 2 through fixed keyway and hole for hoist, facilitates bearing It is whole to be fixedly mounted；Spacer ring is equipped with fixing screw hole 9, and outer ring is equipped with annular groove 10, and spacer ring extends on the outer diameter of outer ring, with Screw passes through fixing screw hole 9 and is fixed into annular groove, to the two-way positioning of outer ring axially and radially, improves the steady of contact It is qualitative, reduce race deformation and abrasion.Spacer ring is widened and increases spacer ring intensity, reduces spacer ring deformation simultaneously, controls radial direction Play.Spacerband width is greater than outer ring and rolling element contact width, and without departing from bearing overall width.
