Arrangement for inclined rolling of tube-shaped or bar shaped rolling products

An arrangement for inclined rolling of tube-shaped or bar-shaped rolling products, comprising at least two rollers adapted to receive therebetween a rolling product so as to determine a longitudinal axis of the rolling product, said rollers being driveable and rotatable about said longitudinal axis, said rollers having roller axes inclined at an inclination angle relative to said longitudinal axis, said roller axes being inclined in such a plane which, when considered in or against the longitudinal axis, extends parallel to said longitudinal axis at a radial distance from it;

• means for driving said rollers, said driving means including a sun gear and drive gears provided with an axis-offset bevel gear toothing and surrounding a respective one of said roller axes, said drive gears engaging with said sun gear so that said rollers are driven by said sun gear through said drive gears, said drive gears which engage said sun gear having a hub region provided with a hollow toothing;
• a plurality of shafts each supporting a respective one of said rollers and having an outer toothing engaging in said hollow toothing;
• and rotatable eccentric bushings each supporting a respective one of said shafts so that said shafts are transversely adjustable relative to said drive gears and said longitudinal axis.

An arrangement for inclined rolling of tube-shaped or bar-shaped rolling products, comprising at least two rollers adapted to rotate about an axis of a rolling product and having roller axes which extend at an inclination angle to the axis of the rolling product and also, for producing a rolling product feed are arranged at a radial distance from said longitudinal axis of the rolling product;

• means for driving said rollers and including a sun gear which surrounds the longitudinal axis of the rolling product and drives said rollers, said means for driving also including drive gears each engaging with said sun gear, each surrounding an axis of a corresponding one of said rollers and driving said corresponding one of said rollers, and each provided with an axis-offset bevel gear toothing.

An arrangement for inclined rolling of tube-shaped or bar-shaped rolling products, comprising at least two rollers adopted to receive therebetween a rolling product so as to determine a longitudinal axis of the rolling product, said rollers over their whole axial length being conical and each supported only at one axial end, said rollers being driveable and rotatable about said longitudinal axis, said rollers having roller axes inclined at an inclination angle relative to said longitudinal axis, said roller axes being inclined in such a plane which, when considered in or against the longitudinal axis, extends parallel to said longitudinal axis at a radial distance from it;

• and means for driving said rollers, said driving means including a sun gear provided with outer bevel-gear toothing and arranged to surround the rolling product and also drive gears provided with an axis-offset bevel gear toothing and surrounding a respective one of said roller axis, said drive gears directly engaging outside with said sun gear so that each of said rollers is driven by said sun gear through a single one of said drive gears, said rollers being adjustable in a direction of said roller axes.

An arrangement for inclined tolling of tube-shaped or bar-shaped rolling products, comprising at least two rollers adapted to receive therebetween a rolling product so as to determine a longitudinal axis of the rolling product, said rollers over their whole axial length being conical and each supported only at one axial end, said rollers being driveable and rotatable about said longitudinal axis, said rollers having roller axes inclined at an inclination angle relative to said longitudinal axis, said roller axes being inclined in such a plane which, when considered in or against the longitudinal axis, extends parallel to said longitudinal axis at a radial distance from it;

• and means for driving said rollers, said driving means including a sun gear provided with outer bevel-gear toothing and arranged to surround the rolling product and also drive gears provided with an axis-offset bevel gear toothing and surrounding a respective one of said roller axis, said drive gears directly engaging outside with said sun gear so that each of said rollers is driven by said sun gear through a single one of said drive gears;
• and shafts supporting said rollers, said drive gears which engage with said sun gear being arranged on said shafts and connected with said shafts for joint rotation therewith.
