Method for producing a bearing seat on shaft for electric machine e.g. small motor, involves producing a ribbed profile on a shaft with milling tools.

摘要

A shaft (1) has first (A), second (B) and third (C) areas. The first is a standard shaft area with a diameter (D). The second shows the shaft after a first cold reduction stage for producing a rib profile (2) with humps (3) and hollows (4) each forming a V-shape. Each hump is next to a hollow. The humps and hollows run over the whole circumference of the shaft each lying parallel to each other. An Independent claim is also included for a milling device for producing a surface or a fit on a rotationally symmetrical component.
