There’s nothing better than looking through some of the photos of jobs that have gone through the doors at All Torque Transmissions. We have our ‘Archives‘ page, which shows some of the gearboxes and other products from our history.
You can see that we get involved with the full gamut of the mechanical power transmission spectrum.
All Torque Transmissions distributes the Bonfiglioli helical-bevel gearmotor range, known as the ‘A’ Series. These gearboxes are very common for conveyor drives, where their relatively small size to output torque ratio helps to keep overall conveyor sizing down in compact areas.

All Torque Transmissions is a distributor for the Flender Fludex coupling range.
Fludex couplings are hydrodynamic fluid couplings which operate on the Föttinger principle. The coupling parts on the input and output sides are not mechanically connected to each other. Output is transmitted via the oil filling which rotates in the coupling and is conducted over radially arranged blades.
Fluid couplings limit starting and maximum torque in the drive train and, through the property of rotational slip, serve as an aid to starting the motor, as overload protection in the event of fault and for isolating torsional vibration.
When large masses are started up, the drive train is accelerated only at the torque determined by the coupling characteristic. The starting operation is spread over time, the driven machine started softly and smoothly.
In the case of special operating conditions, such as overload or blocking of the driven machine, the effect of the motor mass is eliminated and the maximum torque load of the drive train limited by the fluid coupling.
Fludex couplings are used in drives for conveyor systems such as belt conveyors, bucket elevators and chain conveyors. In heavy industry fluid couplings are used for applications such as blade wheel drives, crushers, roller presses, mixers, large ventilators, boiler feed pumps, large compressors, centrifuges and auxiliary drives for mills.
Further applications include pump drives, PTO generator drives, windpower systems and door and gate drives. In drives with diesel engines, Fludex couplings are used on driven machines with a high mass moment of inertia.
Fludex couplings are constructed of just a few, robust components. Internal components include the hollow shaft or solid shaft, to which the blade wheel is connected. The outer housing comprises the cover and the blade wheel housing. The joint is constructed as a bolted flange joint and sealed with an O ring. The outer housing and the shaft or hollow shaft have double bearing support and are sealed off to the outside with radial shaft seals.
The coupling is provided with two filler plugs with integral overflow protection and with one or two fusible safety plugs in the coupling housing for protection against overheating. The fusible safety plug or a screw plug fitted in the same position also serves as a fluid drain plug and with the aid of a scale marking on the housing can be used as a level indicator.
