- a further preferred embodiment of the cone-shaped sheet metal part is characterized in that the support leg, relative to the axis of rotation of the cone-shaped sheet metal part, is curved outward.

- the toothing serves to rotate the cone-shaped sheet-metal part, but in the axial direction limited to connect to a shaft, in particular a hollow shaft, on which a designed as a loose disk cone pulley is arranged with the cone-shaped sheet metal part according to the invention.
- a further preferred embodiment of the conical-plate shaped part is characterized in that from the free end of the conical leg a boundary plate extends, which extends parallel to the axis of rotation of the conical-plate shaped part.
- the boundary plate is preferably cohesively, for example by welding, connected to the cone limb.
- the boundary plate can also be integrally connected to the cone limb.
- the invention further relates to a conical disk with a previously described conical-shaped sheet metal part.
- the conical disk is preferably designed as a loose disk or distance disk, but may also be designed as a fixed disk. If appropriate, the invention also relates to a method and / or a tool for producing a previously described conical-disk sheet metal part.
