Abstract
A toothing, in particular of a drive spindle for driving a roll in rolling mills or continuous casting plants, which has several teeth and meshes with a second toothing in the manner of a spline, wherein a flank line of the teeth has a curvature, and a deflection angle is formed between the rotational axis of the second toothing and the rotational axis of the drive spindle toothing, and wherein the teeth of drive spindle toothing have a twist in form of profile angle deviation over the tooth width in the flank direction.
Claims15
Spline spur toothing for force transmission from a drive shaft to a driven member arranged at angle to each other, comprising a first spur toothing (1) engaging in a second spur toothing provided on the driven member,
- wherein the first spur toothing (1) has a plurality of spur teeth (2), wherein a flank line (12) of each spur tooth (2) has a curvature, and a deflection angle (β) is formed between a rotational axis of the second spur toothing and a rotational axis of the first spur toothing, and
- wherein a flank of the spur tooth (2) is formed with a twist in form of a profile angle deviation (φ) in direction of the flank of the spur tooth (2) in a vertical plane.
Device for driving a roll in a rolling mill, comprising a shaft (15) with a first spur toothing (16, 17) engaging in a second spur toothing (18, 19) of a drive spindle for driving the roll (13), wherein each spur toothing has a plurality of spur teeth (2), wherein a flank line (12) of each spur tooth (2) of the first and second spur toothings (16, 17) has a curvature and a deflection angle (β) is formed between a rotational axis of the second spur toothing and a rotational axis of the first spur toothing, wherein, a flank of each spur tooth (2) of the first and second spur toothings is formed with a twist in form of a profile angle deviation (φ) in direction of the flank of the spur tooth (2) in a vertical plane, and wherein the first and second spur toothings (16, 17, 18, 19) are spline spur toothings.
