Abstract
Welded axle housings with hollow axles are manufactured by providing the edges of the axle housing with beadings and finishing the fitting and abutment surfaces thereof as well as of the hollow axles, assembling the axle housing and the hollow axles, clamping in the assembly and connecting its parts by electron beam welding along frontal abutment faces on said beadings.
Claims1
In a method of manufacturing axle housings of sheet metal with hollow axles, the steps of:
- forming a beaded edge on each side of a sheet metal axle housing by means of plastic deformation;
- machining both the axle housing and the hollow axles so as to have mutually abutting front surfaces;
- fitting the hollow axles each in one of the beaded edges of the axle housing along said mutually abutting front surfaces;
- clamping the axle housing with the fitted in hollow axles in a clamping device;
- and connecting the hollow axles with the axle housing along said mutually abutting front surfaces by means of electron beam welding.
