To assemble the Uneflex coupling, mount the hubs (1) together with the pressure rings (2) on the shaft ends and align the system parts. The distance between the hubs “n” must be the one indicated on the data sheet.
The tyre (3) is mounted on the coupling hubs, fitted to provide the smallest possible gap between its faces. For large couplings, before tightening the pressure rings, it is recommended to use clamping bands to fit the tyre. The tyre is secured with the prescribed wrench torque by means of the pressure ring and the screws (4). The fixation must be always carried out tightening two diametrally opposite screws in cyclic order, retightening the bolts after the first tightening as the rubber settles.
For replacing the tyre, only loosen the screws, until the tyre can be withdrawn.
Scope of delivery in the standard version includes:
| Component No. | Quantity | Description | Material |
|---|---|---|---|
| 1 | 2 | Hub | Steel |
| 2 | 2 | Pressure Ring | Steel |
| 3 | 1 | Tyre | Rubber |
| 4 | - | Screw | Steel |
Storage and maintenance
In order to ensure a long-life cycle of the rubber element, it is fundamental to store the tyre protecting it against ozone, light (specially ultra violet rays), heat and oxygen, in a room with a relative humidity of less than 65% with a storage temperature range between +10 °C and +25 °C and without storing in the same room disinfectants, acids, chemicals and other similar substances that may cause a depreciation of the tyres.
Further details of the guideline for rubber product storage can be found in the standard ISO 2230.
The coupling design allows a perfect inspection of the transmission tyre without dismantling the coupling, so a periodical visual inspection is recommended.
