A gear mechanism () for a rolling mill drive includes at least one involute cylindrical gear tooth system between at least two intermeshing gear wheels () with asymmetrical gearing. The normal pressure angle of the load-bearing tooth flanks () of the gear wheels () is greater than 20° and less than or equal to 30°, and the normal pressure angle of the trailing flanks () of the gear wheels is greater than or equal to 14° and less than 22°. A rolling mill drive has a gear mechanism () of this type, and the gear mechanism () is used as a rolling mill gear mechanism.

The invention relates to a rolling mill drive () having an axially displaceable toothed articulated spindle () extending between a toothed articulated element (arranged between an interlocking chamber () on the roller side and a toothed articulated element () arranged in an interlocking chamber () on the transmission side, wherein at least one of the interlocking chambers () is filled with a lubricating medium, wherein the lubricating medium biases the toothed articulated spindle () with an axial force (F) directed towards the roll side (WS).

A position detector used with a roll stand having a fixed frame member and a roll-carrying member movable in a direction relative to the frame member, has first and second sleeves telescoping in the direction adjacent the members, a mount securing one of the sleeves to one of the members, and a fixed-length but elastically bendable link rod extending in the direction and having one end fixed to the other of the members and an opposite end fixed to the other of the sleeves. Thus on relative movement of the fixed and movable members the sleeves slide in the direction in each other. A sensor rod having one end fixed in the first sleeve extends in the direction into the second sleeve. A position sensor in the second sleeve juxtaposed with the sensor rod determines a position of the members relative to each other in the direction.
