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).
Claims15
A set of modular elements for the construction of a driving pulley comprising:
- a metallic shaft having two ends at which are located an axial bearing journal and a coupling located at at least one of the two ends for attachment to at least one drive wheel which transfers driving power from the drive wheel to the driving pulley, at least one disk element and at least two end pieces each of a synthetic material and on the metallic shaft, a plurality of connectors for clamping the end pieces together around the at least one disk element, each disk element having a central axial polygonal opening which engages the metallic shaft which has a polygonal cross section corresponding to the polygonal opening, and a ratio between diameter of the metallic shaft and an outer diameter of the pulley is such that the outer diameter is between 2.5 and 4.5 times the diameter of the shaft.
