Flexible coupling / drum type

Barrel Drum coupling
The TONOFLEX drum coupling has an unmatched reputation
in Engineering Departments specialised in the hoisting
and handling this coupling has specially been designed
to eliminate the needs for considerable adjustment
normally associated with rigid transmissions.
DESCRIPTION
The hardened steel barrels are used as power transmission
elements, which are located between the hub and the ring.
From size 2, the NTT design provides great safety when
the TONOFLEX is used at the limits of its misalignment capacity.
This is achieved by axially locating the barrels by means
of heat treatment steel rings and circlips.
ADVANTAGES
Acceptance of large radial forces.
Possible angular misalignment up to ± 1°30? max.
Axial displacement from ± 3 mm to ± 8 mm can be absorbed according to the sizes.
Minimum movement of slipping the teeth, thanks to the barrel being balanced.
High safety against the overloads.
High wear resistance.
The design excludes the risk of tooth breakage due to the bending stress.
External control of wear is permitted thanks to an index fxed on the outer
cover without coupling dismantling.Thanks to this index and appropriate marks
on the coupling hub, the axial positioning of the cover into the hub is easier
