Abstract
A method for producing a shaft and a device containing such a shaft (22), in particular an armature shaft (22) of an electric motor drive (10), which shaft is held by at least one shaft bearing (43), includes forming a bearing surface (40) for guidance in a shaft bearing (42) onto the shaft (22) at at least one point by positive displacement of material.
Claims9
A method of producing a shaft of an electric motor drive, which shaft is held by at least one shaft bearing, the method comprising the steps of forming first a worm onto the shaft;
- and after said forming the worm onto the shaft, forming at least one bearing surface for a guiding in a shaft bearing onto the shaft at at least one point in the region of the worm by means of positive displacement of material that includes at least partially cold-forming worm teeth in the positive displacement of material, and forcing a tooth material into tooth gaps to form said at least one bearing surface.
A method for producing a shaft of an electric motor drive, which shaft is held by at least one shaft bearing, the method comprising the steps of forming a bearing surface onto the shaft at at least one point by means of positive displacement of the material, said forming including forming at least one bearing surface by means of rolling, using smooth-rolling tools.
