The invention controls the rotation of the outer ring of the bearing by adopting the structures such as the outer spacer ring and the like. So that the bearing can work normally. Thereby prolonging the service life of the bearing and reducing the cost.
Description
Technical Field
The invention relates to the technical field of bearings, in particular to a novel double-row tapered roller bearing for bearing axial force.
Background
The double-row tapered roller bearing is applied to rolling mill equipment, and the structure comprises an inner ring, two outer rings and an outer spacer ring. The bearing bears axial force during operation, the outer diameter of the bearing is in clearance fit with the inner hole of the box body of the equipment, and the clearance amount is generally 0.15-2 mm. Radial forces are borne by the four-row cylindrical roller bearing. Therefore, the outer ring of the double-row tapered roller bearing is pressed by the axial positioning sleeve, and the outer ring is fixed. However, if the bearing is suspended on the roller with a gap when the bearing is not tightly pressed, the axial force is larger when a row of rollers works, and the gap between the outer ring and the shell is larger, so that the outer ring and the inner ring assembly of the bearing do not roll relatively, but rotate along with the shaft of the equipment. The bearing loses the rolling and bearing functions. Therefore, the locating sleeve of the fixed equipment has sliding friction with the outer ring, and the outer ring can be cracked due to serious friction.
Disclosure of Invention
The invention aims to solve the problems, and provides a novel double-row tapered roller bearing for bearing axial force, which prevents an outer ring from rotating, so that the defects of small bearing capacity, small rigidity, short service life, poor shock resistance and the like of the original double-row tapered roller bearing are overcome.
In order to solve the technical problems, the technical scheme of the invention is as follows: the novel bearing for bearing the axial force of the double-row tapered roller comprises an outer spacer ring, an outer ring, rollers, a retainer and an inner ring; rollers are obliquely and symmetrically arranged on the outer circumferences of the two sides of the inner ring, retainers are symmetrically arranged at the two ends of the inner ring, outer rings are symmetrically sleeved outside the rollers on the two sides, and the two outer rings are connected through an outer spacer ring; at least one section of arc-shaped bulge is arranged on the circumferences of the two ends of the outer space ring, at least one section of arc-shaped groove is correspondingly arranged on the circumference of the end face of the outer ring connected with the outer space ring, and oil holes are formed in the circumference of the outer space ring.
Further, the method comprises the steps of, arc-shaped bulge and outer ring of outer spacer ring the number of the circular arc grooves is equal.
The invention controls the rotation of the outer ring of the bearing by adopting the structures such as the outer spacer ring and the like. So that the bearing can work normally. Thereby prolonging the service life of the bearing and reducing the cost.

Detailed Description
Embodiments of the present invention will be further described with reference to fig. 1-10.
The novel double-row tapered roller bearing for bearing axial force comprises an outer spacer ring 1, an outer ring 2, rollers 3, a retainer 4 and an inner ring 5; the outer circumferences of the two sides of the inner ring 5 are inclined and symmetrically provided with rollers 3, the two ends of the inner ring 5 are symmetrically provided with retainers 4, the outer sides of the rollers 3 on the two sides are symmetrically sleeved with outer rings 2, and the two outer rings 2 are connected through an outer spacer 1; at least one section of arc-shaped bulge is arranged on the circumferences of the two ends of the outer space ring 1, at least one section of arc-shaped groove is correspondingly arranged on the circumference of the end face of the outer ring 2 connected with the outer space ring 1, the number of the arc-shaped bulge of the outer space ring 1 is equal to that of the arc-shaped groove of the outer ring 2, and oil holes are formed in the circumference of the outer space ring 1.
The two outer rings 2 are connected through the outer spacer ring 1, and the outer diameter of the outer spacer ring 1 is contacted with the shell to generate friction resistance, so that the purpose of preventing the outer rings 2 from rotating is achieved.
The present invention is not limited to the above-mentioned embodiments, but any person skilled in the art, based on the technical solution of the present invention and the inventive concept thereof, can be replaced or changed equally within the scope of the present invention.
