ABSTRACT:
A set of modular elements for the construction of a driving pulley (1) for belt conveyors or the like comprises a steel shaft (3), at least one disk element (2) of synthetic material and at least two end pieces (8), similarly of synthetic material, plus a number of bolts (11) with nuts (12) arranged for the tightening together of the end pieces around the disk element(s) in such a manner that the shaft is secured in the pulley.
In the area for the disk elements (2), the shaft (3) is hexagonal in shape (5) and each disk element has a corresponding axial opening, and the shaft comprises an axial bearing journal (6) at each end and a trunnion (7) for at least one drive wheel (16).
The driving pulley is preferably coated with a rubber or rubber-like lagging (4).
