A transmission shaft assembly for a rolling stand for use in a metal rolling mill is provided. The transmission shaft assembly transmits lubricant through the assembly. The transmission shaft assembly includes a shaft having an outer periphery and defining a centrally positioned longitudinal opening extending from a first end to an opposed second end of the shaft. The shaft defines a plurality of internal passageways in the shaft. The transmission shaft assembly also includes a rotary distributor mounted on the outer periphery of the shaft. The shaft assembly provides a conduit for the lubricant through the plurality of internal passageways in the shaft.

A method for producing an internally and/or externally toothed pot-shaped sheet metal part having teeth extending toward the pot center axis, wherein an un-toothed pot-shaped sheet metal part is inserted into a die and then, by means of a relative movement between the sheet metal part and associated profile rollers, a profile is rolled onto the pot-shaped sheet metal part by the profile rollers applied to the sheet metal part and thus alternating internal and external gear teeth are applied to the sheet metal part, wherein the profile rollers form the sheet metal part oriented radially from the inside toward the outside, in that the profile rollers roll along the inner circumference of the sheet metal part.

A roll for continuous casting comprises a cylindrical roll rotatably mounted on a fixed axle and having a cooling chamber that surrounds the axle for receiving a flow of coolant. The axle is mounted on a roll support system. The roll support system comprises a first roll support connected to a coolant supply system and a second roll support connected to a coolant drain system. The axle comprises a first inlet connected to the first roll support, a first outlet connected to the coolant chamber, a second inlet connected to the coolant chamber, and a second outlet connected to the second roll support. A coolant flow circuit has a flow path from the coolant supply system to the coolant drain system through the first roll support, the first inlet, the first outlet, the coolant chamber, the second inlet, the second outlet, and the second roll support.
