Method for roll-forming disk carriers or the like and the associated profile roller set

摘要

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.

1. 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.
