Can be produced in accordance with the requirements of regulation 94/9/CE (ATEX 95) of a group ll device, category 2G or 2D (zone 1) and temperature class T4.
With a flexible body that compensates misalignment and protects other components in the transmission system. These torsionally flexible couplings can be produced in accordance with
the requirements of regulation 94/9/CE (ATEX 95) of a group ll device, category 2G or 2D (zone 1) and temperature class T4.
The fundamental element of the tyre coupling is a neoprene rubber tyre reinforced with a synthetic mesh. It adapts itself to the working conditions, absorbing axial, radial, angular and torsional misalignments and prevents vibration via the transmission to the machines to which they are coupled. It compensates the defect of angular misalignments to 3º, radial misalignment by 4 mm, and axial misalignment of 6 mm.
These mechanical power transmission tyre couplings cushion the effects of overloading, absorb vibrations, reducing noise and protecting the machine from the destructive effects of vibration.
There is no metal to metal contact between the shafts and the hubs are completely isolated. No lubrication is needed.
Replacement: Easy and practical. There is no need to move the motor or other components within the transmission. It is sufficient to release the axial screws, so freeing the coupling. The result is better running of the machine and a longer life for the whole installation.
ONE of the most interesting characteristics of the trye coupling is the very simple way in which the rubber tyre couples. The rubber tyres are set on the coupling's hub and are fixed by means of fastening rings (2) and screws (4).
