Extended range of disc couplingsThe range of Torsiflex disc couplings from Bibby Transmissions has been expanded to offer customers a greater selection for applications in process pumps, fan blowers, compressors and general industrial markets. The Torsiflex coupling consists of 2 hubs and a factory assembled transmission unit.
In the past, the size of the coupling was determined by a combination of shaft diameter and torque requirement - in some cases the size of the hub forced the use of a larger coupling than would otherwise have been nece-ssary. This con-straint has been solved by the introduction of the new AHX hub, which has been developed to accommodate large diameter shafts on process equipment.
The new AHX hub solves a number of issues within this area; the ability to accept larger shaft diameters means that coupling sizes can be kept to a minimum. Previously, equipment with a large shaft diameter necessitated a larger coupling which was not only more expensive, but also heavier, which could cause problems for the bearing assemblies. With the AHX hub, the weight is minimised and the performance of the plant maximised.
When it comes to maintenance, in applications such as pumps, compressors and fans, there can be a requirement for the coupling to be removed on a regular basis. The time required for this operation has been greatly reduced with the AHX hub, where the retaining bolt direction has been reversed to simplify this procedure.
