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).
Claims8
A process for connecting functional elements to a shaft of a mixer, kneader, stirrer or comminutor for polymer 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 and removing material from an 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 polymer materials.
