A method for roll-forming disk carriers or the like, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in their interior, which roll out the disk carrier to be formed with their outer circumference and thus impart toothing on the disk carrier to be formed, wherein the forming depth of the profile rollers at the disk carrier to be formed is designed in such a way that a narrow, peripheral, self-contained, unformed bridge remains between the inner diameter and the outer diameter of the toothing, wherein the bridge increases the engine-speed strength of the disk carrier as a hoop band cylinder that is integrated into the toothing.
A method for roll-forming disk carriers, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in an interior of the profile rollers, the method comprising rolling out the disk carrier to be formed with an outer circumference of the profile rollers to form toothing on the disk carrier to be formed, the profile rollers having a forming depth at the disk carrier to be formed that creates a narrow, peripheral, self-contained, unformed bridge remaining between an inner diameter and an outer diameter of the toothing, wherein said bridge forming a hoop band cylinder that is integrated into the toothing to increase engine-speed strength of the disk carrier.
A profile roller set for roll-forming disk carriers, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a roll-forming tool, said cassettes having profile rollers arranged in an interior of the cassettes, which roll out the disk carrier to be formed with an outer circumference of the profile rollers to form toothing on the disk carrier to be formed, wherein a forming depth of the profile rollers at the disk carrier to be formed is dimensioned in such a way that a narrow, peripheral, self-contained, unformed bridge remains between an inner diameter and an outer diameter of the toothing, wherein said bridge is configured as a hoop band cylinder (16) that is integrated into the toothing to increase engine-speed strength of the disk carrier.
A method for spin-forming disk carriers, which are designed as a pot-shaped sheet metal part having inner and outer teeth, wherein a multitude of cassettes is equidistantly arranged on the circumference of a tool, said cassettes having spinning tools arranged in an interior of the cassettes and profile elements disposed at a front surface of the spinning tools, the method comprising shaping the disk carrier to be formed with an outer circumference of the profile elements to form toothing on the disk carrier to be formed, the profile elements having a forming depth for the disk carrier to be formed dimensioned such that a narrow, peripheral, self-contained, unformed bridge remains between an inner diameter and an outer diameter of the toothing forming a hoop band cylinder that is integrated into the toothing to increase engine-speed strength of the disk carrier.
