Abstract
The invention relates to a toothing, in particular of a drive spindle for driving a roll in rolling mills or continuous casting plants, which comprises 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 toothing, wherein the toothing (1) is designed as having at least one of the following modifications: a tooth root relief of the teeth (2), and/or a tooth tip relief of the teeth (2), and/or a twist of the teeth (2).

1-14. (canceled)
Spline toothing having a toothing (1) engaging in a second toothing, in particular of a drive spindle for driving a roll (13) in a rolling mill or a continuous casting installation, wherein the toothing (1) has many teeth (2), wherein a flank line (12) of the teeth (2) has a curvature and a deflection angle is formed between a rotational axis of the second toothing and a rotational axis of the toothing,
- characterized in that:
- the teeth (2) are formed with a twist in form of a profile angle deviation φ in direction of the flank of a tooth (2).
Device for driving a roll of a metallurgical installation, comprising a shaft (15) with a toothing (16, 17, 18, 19) having engaging in a second toothing, in particular of a drive spindle for driving a roll (13) in a rolling mill or a continuous casting installation, wherein the toothing (1) has many teeth (2), wherein a flank line (12) of the teeth (2) has a curvature and a deflection angle is formed between a rotational axis of the second toothing and a rotational axis of the toothing,
- characterized in that:
- the teeth (2) are formed with a twist in form of a profile angle deviation φ in direction of the flank of a tooth (2), wherein the shaft (15) includes the toothing (16, 17) of the spline toothing (16, 17, 18, 19).
Method of producing a spline toothing having a toothing (1) engageable in a second toothing wherein the toothing (1) has many teeth (2), wherein a flank line (12) of the teeth (2) has a curvature and a deflection angle is formed between a rotational axis of the second toothing and a rotational axis of the toothing,
- characterized in that:
- the teeth (2) are formed with a twist in form of a profile angle deviation φ in direction of the flank of a tooth (2), including the step:
- producing the toothing (1) with a plurality of teeth,
- characterized in that
- the following steps of after-treatment are carried out on the produced toothing so that a rotational axis of the toothing (1) can be driven at a deflection angle to a rotational axis of the second toothing:
- treating flank lines (12) of the toothing (1) so that those have a curvature;
- treating the teeth (2) so that they are formed with a twist in form a profile angle deviation φ in direction of the flank of the tooth (2).
