Abstract
A method for connecting functional elements (14) to a shaft (10, having the following steps: (a) forming elevations (12) for receiving the functional elements (14), said elevations (12) being machined out of the shaft (10) by removing material, and (b) welding the functional elements (14) to the elevations (12) on the shaft (10).
Claims11
A process for connecting functional elements to a shaft of a mixer, kneader, stirrer or comminutor for liquid or solid materials, comprising the following steps:
- (a) forming elevations on a shaft of a mixer, kneader, stirrer or comminutor for receiving functional elements wherein the elevations are formed by providing a circular-cylindrical shaft having an outer cylindrical surface without blade roots and removing material from the outer cylindrical surface of the circular-cylindrical shaft so as to define the elevations as continuous integral portions of the shaft;
- and
- (b) welding the functional elements to the elevations on the shaft, wherein the functional elements are bars, blades, arms, hooks, journals, helices, paddles, knives or studs for processing the liquid or solid materials.
