Abstract

The utility model provides an automatic self-aligning bearing unit of half inner circle, includes bearing frame lower base, bearing frame upper cover, bearing assembly, two sealing rings and half outer lane, and bearing assembly installs in the bearing frame lower base, and the bearing frame upper cover is detained and is established in the upper end department of bearing frame lower base, its characterized in that bearing frame lower base inner wall is provided with the arc concave wall, and half outer lane outside periphery is provided with the arc convex wall, and half outer lane is sat and is established in the bearing frame lower base, and the convex wall of arc and the concave wall phase-match of arc, and a plurality of rollers in the bearing assembly are sat and are established on half outer lane. The utility model discloses have the function of automatic aligning, because the guide roll receives heavy burden and than big bearing, have the problem that takes place flexural deformation, shock resistance is superior, can absorb the shock wave energy under the complicated load, bear great impact load, stand wear and tear, life is higher than the roll.

Description

Semi-inner ring automatic aligning bearing unit

Technical Field

The utility model relates to a bearing unit technical field, in particular to automatic self-aligning bearing unit of half inner circle.

Background

The bearing of the continuous casting machine is in an environment with heavy load, low speed and high temperature, and must also operate in an environment seriously polluted by moisture, steam and iron oxide chips. The current development of the continuous casting process: under the conditions of high temperature and heavy load, the rollers expand by heating to generate axial displacement and can generate flexural deformation, the full-complement cylindrical roller bearing realizes the capacity of bearing heavy load and absorbing the axial displacement of the rollers expanded by heating, but the cylindrical roller bearing does not have the function of automatic centering, and the split bearing unit is required to solve the function of automatic centering.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at the above-mentioned problem that exists among the prior art, and provide a half inner circle automatic aligning bearing unit, this unit has the function of automatic aligning, bears great impact load, and life is higher than the roll, is applied to normal work under the adverse circumstances.

The utility model adopts the technical proposal that:

the utility model provides an automatic self-aligning bearing unit of half inner circle, includes bearing frame lower carriage, bearing frame upper cover, bearing assembly, two sealing rings and half outer lane, bearing assembly install in the bearing frame lower carriage, two sealing rings are installed respectively in the bearing assembly both sides, the bearing frame upper cover is detained and is established the up end department at the bearing frame lower carriage, the both sides up end butt joint of both sides lower end of bearing frame upper cover and bearing frame lower carriage and through bolt fixed connection an integrated structure. The bearing seat is characterized in that an arc-shaped concave wall is arranged on the inner wall of the lower seat of the bearing seat, an arc-shaped convex wall is arranged on the periphery of the outer part of the half outer ring, the half outer ring is arranged in the lower seat of the bearing seat in a seating mode, the arc-shaped convex wall is matched with the arc-shaped concave wall, and a plurality of rollers in the bearing assembly are arranged on the half outer ring in a seating mode.

The utility model has the advantages that: 1. the guide roller has the function of automatic centering, and has the problem of flexural deformation because the guide roller is loaded by a large load ratio; 2. the shock resistance is excellent, the shock wave energy under complex load can be absorbed, and larger shock load can be borne; 3. the wear resistance is higher than that of a roller in service life; 4. the lubrication adaptability is good; 5. the sealing performance is good, and the sealing device can normally work in severe working environments of acid water, dust, scale fragments and dirt.

Detailed Description

The utility model provides an automatic self-aligning bearing unit of half inner circle, includes bearing frame lower base 1, bearing frame upper cover 2, bearing assembly 3, two sealing rings 4 and half outer lane 5, bearing assembly 3 install in bearing frame lower base 1, two sealing rings 4 are fixed respectively and are installed in bearing assembly 3 both sides, bearing frame upper cover 2 is detained and is established in the up end department of bearing frame lower base 1, the both sides up end butt joint of terminal surface and bearing frame lower base 1's both sides up end of bearing frame upper cover 2 becomes the integral structure through bolt fixed connection. The bearing seat lower seat is characterized in that an arc-shaped concave wall 6 is arranged on the inner wall of the bearing seat lower seat 1, an arc-shaped convex wall 7 is arranged on the periphery of the outer portion of the half outer ring 5, the half outer ring 5 is arranged in the bearing seat lower seat 1 in a sitting mode, the arc-shaped convex wall 7 is matched with the arc-shaped concave wall 6, a plurality of rollers 8 in the bearing assembly 3 are arranged on the half outer ring 5 in a sitting mode, the arc-shaped convex wall 7 is in contact with the arc-shaped concave wall 6 to achieve the effect that the bearing unit bears eccentricity and has the automatic centering function, the problem of deflection of the rollers 8 under heavy load is solved, and the phenomenon that the edge stress of the rolling body is sharply increased to accelerate abrasion and stripping is prevented.
