Abstract
A support roller, particularly for rolling mill systems or equipment for casting, conveying or straightening metal products, including a cylindrical roller axle, a hollow cylindrical outer ring arranged concentrically in relation to the roller axle, and a plurality of rolling bodies arranged between the roller axle and the outer ring. The roller axle further including a cavity, at least in certain sections between its central axis and a load introduction point. Due to the provision of the cavity the load rating and the service life of the support roller are increased.
Claims20
A support roll for rolling mill systems or equipment for casting, conveying, or leveling of metal products, comprising:
- a substantially cylindrical roll axle;
- a hollow cylindrical outer ring arranged concentrically to the roll axle;
- and
- a plurality of rolling elements arranged between the roll axle and the outer ring,
- wherein the roll axle, at least in certain sections, comprises a cavity arranged eccentrically to a center axis of the roll axle, the cavity being arranged substantially between the center axis and a point at which load is introduced into a circumference of the support roll, wherein the cavity is configured as a bore that extends substantially parallel to the center axis of the roll axle, wherein a center axis of the bore is located in a plane passing between the load introduction point and the center axis of the roll axle.
A method for producing a support roll comprising a substantially cylindrical roll axle, a hollow cylindrical outer ring arranged concentrically to the roll axle, and a plurality of rolling elements arranged between the roll axle and the outer ring, wherein the roll axle, at least in certain sections, comprises a cavity arranged eccentrically to a center axis of the roll axle, the cavity being arranged substantially between the center axis and a point at which load is introduced into a circumference of the support roll wherein the cavity is configured as a bore that extends substantially parallel to the center axis of the roll axle wherein a center axis of the bore is located in a plane passing between the load introduction point and the center axis of the roll axle, the method comprising the steps of:
- providing a roll axle;
- introducing an eccentric bore into the roll axle so that the bore extends substantially parallel to the center axis of the roll axle wherein a center axis of the bore is located in a lane passing between the load introduction point and the center axis of the roll axle;
- and
- assembling the roll axle, rolling elements, and a hollow cylindrical outer ring to form the support roll, wherein the rolling elements form a rotatable bearing between the outer ring and the roll axle.
