Visually perceived versatility is displayed by gripping the T-Bar Ends of the flexible Bellows/Spring Clutch SAFETY coupling in each hand & applying manual:-
1. bending, or push/pull actions – to show Angular & Axial misalignment capacity; or
2. twisting torque, to exceed the Safety overload (pre-set by rotating the spring pressure-holding nut to its marked position).
The resultant ‘free-wheel’ stems from ‘caged’ steel ball bearings rolling out along their detent grooves. Lowering torque below its overload limit again, returns them to the next hole, if ‘symmetrical’ (after 360°, if ‘asymmetrical’) & re-connects the drive. Response is exceptionally fast; within milli-seconds. A proximity switch can cut off power by detecting axial movement of the pressure plate.

Following a successful introduction on the first line, in 2006, the decision to replace a further 40 small hydraulic motors mounted on rolls, in pairs, on a second 20-stand food forming line was taken. As before, this included scrapping their inefficient, high energy consuming, hydraulic power pack source too. Higher efficiency, geared Electric Motor drive unit pairs, finely controlled by linked Inverters, provided the replacements. However, the smaller, light hydraulic motors were roll end mounted & adjusted their position with them – whereas, the much larger, longer and heavier, geared motor power units, could not be easily moved in tandem with roll adjustment and they had wider paired shaft centres than their roll centres, anyway.

Packing up POGGI Conical ‘LOK-FIT’ Rings for export to Indonesia, for mounting conveyor drive pulleys onto drive shafts, without Keys, in a cigarette production factory. The Conical Rings expand, both inwards onto the shaft and outwards onto the pulley bore, by tightening the ‘cones’ into each other. A number of axial tension bolts locate around the Ring annulus to achieve this. Distribution of applied transmission load over the total bore surface contact areas makes this an ideal shaft connection method, avoiding ‘fretting corrosion’ and offering any phasing position, with simple installation & removal.
