Abstract

A long cylindrical full roller bearing with an aligning housing ring and for a continuous casting machine comprises an outer ring and an inner ring, wherein the outer wall of the outer ring is a spherical outer wall; a column of long cylindrical rollers is installed inside a rollaway nest formed by the outer ring and the inner ring; the long cylindrical rollers are logarithmic curve modified rollers; the outer ring is sleeved with an aligning housing ring; the inner wall of the aligning housing ring is a spherical inner wall; the spherical outer wall of the outer ring is in matching contact with the spherical inner wall of the aligning housing ring, and the rotating center of the spherical outer wall of the outer ring is concentric with the spherical center of the spherical rollaway nest of the aligning housing ring, so that the long cylindrical full roller bearing with the aligning housing ring is formed. The long cylindrical full roller bearing with the aligning housing ring can adapt to flexure of the rollers under a heavy load and prevent accelerated abrasion and stripping caused by sharp increase of the edge stress of a rolling body; the inner ring structure has a high capability of satisfying the requirement of axial play; through design of the long cylindrical full roller bearing, the load capability of the bearing is improved to the maximum extent and the impact resistance is high; and the edge stresses of the rollers are reduced and the service lives of the rollers are prolonged.

Description

Long cylinder full type roller bearing with aligning housing ring for a kind of casting machine

Technical field

The utility model relates to a kind of bearing, particularly relates to a kind of traditional conticaster roller free end side long cylinder full type roller bearing that is installed in.

Background technique

The bearing of the free end installing on traditional conticaster roller is generally selfaligning roller bearing, traditional selfaligning roller bearing is by outer ring, inner ring forms with the two row rollers that are installed in outer ring and inner ring formation raceway, although this bearing is conducive to the together configuration of bearing housing, but bearing is not strong to the flexible adaptability of axle, under hot environment, working stability descends, owing to can not absorbing well the axial displacement produced because of thermal expansion, easily make the distortion of roller generation flexing, once the distortion of roller generation flexing just needs to change, thereby affect the working stability of casting machine, reduced manufacturing efficiency, improved cost of production.

The model utility content

The purpose of this utility model, be to provide the long cylinder full type roller bearing with aligning housing ring for a kind of casting machine.Resistance to high temperature is good, support rollers normal operation that can be reliable and stable under 1500 ℃ of hot environments, and bearing load is large, and shock resistance is strong.

The technological scheme adopted is:

Long cylinder full type roller bearing with aligning housing ring for a kind of casting machine, comprise outer ring, inner ring, it is characterized in that:

The outer wall of outer ring is the sphere outer wall;

Be equiped with a row long cylinder roller in the raceway that outer ring and inner ring form; The long cylinder roller is that logarithmic curve is repaiied type;

Outer ring sleeve is equipped with aligning housing ring, and the inwall of aligning housing ring is the sphere inwall; The sphere outer wall of outer ring contacts with the sphere inwall of aligning housing ring coupling, the radial clearance that 0.05-0.1mm is arranged between outer ring and aligning housing ring, and the center of rotation of this outer spherical surface outer ring is concentric with the spherical raceway centre of sphere of aligning housing ring, thereby the long cylinder formed with aligning housing ring completely fills roller bearing; Described long cylinder roller refers to that cylindrical roller length is greater than the length of the cylindrical roller of installing in known selfaligning roller bearing, and the cylindrical raceway length that long cylinder roller length and outer ring of the present utility model inwall are offered adapts.

Advantage of the present utility model:

The utility model band aligning seat outer ring, can adapt to that the deflection of roller under heavy duty prevents the sharply increase of rolling element edge stress and accelerated wear test is peeled off;

The inner ring inner structure has the ability of good solution play requirement;

The design of the full roller of long cylinder has at utmost increased the bearing capacity of bearing, shock proof superior performance; Roller adopts the logarithmic Curve Design, reduces the roller edge stress, improves roller working life.

The utility model, for the free side on conticaster roller, has heat-resisting quantity, back-up roll system normal operation that can be reliable and stable under 1500 degree hot environments; There is the ability that moves axially that absorbs roller expanded by heating amount; Can self-aligning have solved the Guide roller large load of bearing a heavy burden thereby the problem of deflection deformation has occurred; The load of bearing is large, and shock resistance is superior; Wear-resistant lubricated strong adaptability.

Drawing reference numeral: 1 is that outer ring, 2 is that inner ring, 3 is that long cylinder roller, 4 is that aligning housing ring, 5 is that logarithmic curve, 6 is the rounding off face.

Embodiment

Long cylinder full type roller bearing with aligning housing ring for a kind of casting machine, comprise outer ring 1, inner ring 2, it is characterized in that:

The outer wall of outer ring 1 is the sphere outer wall;

Be equiped with a row long cylinder roller 3 in the raceway that outer ring 1 and inner ring 2 form; Long cylinder roller 3 is repaiied type for logarithmic curve 5;

Outer ring 1 is set with aligning housing ring 4, and the inwall of aligning housing ring 4 is the sphere inwall; The sphere outer wall of outer ring 1 contacts with the sphere inwall of aligning housing ring 4 coupling, the radial clearance that 0.05-0.1mm is arranged between the sphere outer wall of outer ring 1 and the sphere inwall of aligning housing ring 4, and the center of rotation of the sphere outer wall of outer ring 1 is concentric with the spherical raceway centre of sphere of aligning housing ring 4, thereby the long cylinder formed with aligning housing ring completely fills roller bearing.
