Abstract
An adjustable deflection roll is illustrated and described having a rotating roll jacket, a carrier which passes axially through the roll jacket and is rotationally fixedly held at its ends in frames and at least one support element which is arranged on the carrier and exerts a support force on the inner side of the roll jacket in a pressing plane. The roll jacket is rotatably held on a bearing housing secured against rotation in the region of at least one of its axial ends by at least one bearing. The roll is of simple layout and easy to exchange in that the bearing housing is secured against rotation at the carrier at at least one roll end within the roll jacket or within an axial projection of the roll jacket.
Claims26
Adjustable deflection roll comprising a rotating roll jacket (1), a carrier 3 which passes axially through the roll jacket (1) and is rotationally fixedly held at its ends in frames (2), and at least one support element (4) arranged on the carrier (3) at the inner side of the roll jacket (1) and exerting a support force in a pressing plane, wherein the roll jacket (1) is rotatably held in the region of at least one of its axial ends by at least one bearing (5, 5a) on a bearing housing (6) secured against rotation, wherein the bearing housing (6) is secured at the carrier (3) against rotation at at least one roll end within the roll jacket (1), or within an axial projection (13) of the roll jacket (1), and
- wherein at least one pair of guide elements (8, 9) which co-operate to secure the bearing housing (6) against rotation is provided at the carrier (3) and at a guide projection (7) of the bearing housing (6) which extends into an intermediate space formed between the carrier (3) and the roll jacket (1) or the axial projection (13).
Adjustable deflection roll comprising a rotating roll jacket (1), a carrier 3 which passes axially through the roll jacket (1) and is rotationally fixedly held at its ends in frames (2), and at least one support element (4) arranged on the carrier (3) at the inner side of the roll jacket (1) and exerting a support force in a pressing plane, wherein the roll jacket (1) is rotatably held in the region of at least one of its axial ends by at least one bearing (5, 5a) on a bearing housing (6) secured against rotation, wherein the bearing housing (6) is secured at the carrier (3) against rotation at at least one roll end within the roll jacket (1), or within an axial projection (13) of the roll jacket (1), and
- Wherein a pair of guide elements (8, 9) is provided between the carrier (3) and the guide projection (7) and in that a further pair of guide elements (10, 11) is preferably provided at the side of the carrier (3) opposite to the guide elements (8, 9), with the two pairs of guide elements (8, 9;
- 10, 11) being arranged on axially oppositely disposed sides of gear set (19, 20) forming the drive for the roll jacket (1).
Adjustable deflection roll comprising a rotating roll jacket (1), a carrier 3 which passes axially through the roll jacket (1) and is rotationally fixedly held at its ends in frames (2), and at least one support element (4) arranged on the carrier (3) at the inner side of the roll jacket (1) and exerting a support force in a pressing plane, wherein the roll jacket (1) is rotatably held in the region of at least one of its axial ends by at least one bearing (5, 5a) on a bearing housing (6) secured against rotation, wherein the bearing housing (6) is secured at the carrier (3) against rotation at at least one roll end within the roll jacket (1), or within an axial projection (13) of the roll jacket (1), and
- Wherein the bearing housing (6) is substantially freely movable relative to the carrier (3) essentially in the pressing plane and perpendicular to the roll axis;
- and in that the guide elements (8, 9;
- 10, 11) co-operate to guide the stroke movement/displacement movement.
