All-in-one combined shaft coupling and slip clutchThe Huco Dynatork clutch-coupling provides mechanical protection and misalignment compensation in a single, compact component. It combines two, time-served Huco Dynatork designs, the first of which is the Oldham coupling that has been an important part of the company's range since the mid-1980s.

Precision engineered throughout, the Huco Dynatork lateral offset Oldham coupling comprises two hubs with inward-facing tenons. These engage with corresponding perpendicular slots in a central lightweight torque disc. As the coupling rotates, the disc compensates for any parallel shaft offset by sliding the commensurate distance along each tenon in turn.

Quality of motion is a function of the carefully controlled relationship between the tenons and the slotted torque disc. The disc is precision moulded from high-grade engineering polymers and, being easily replaced at low cost, is the sacrificial element in the drive train; radiation- and heat-resistant torque discs are also available.

In a conventional Oldham coupling, severe overload will result in the torque disc breaking, thereby acting as a mechanical fuse and protecting associated equipment from damage. A replacement torque disc quickly restores the drive without the need to dismantle the drive system.

Combined coupling and clutch

However, the new Huco Dynatork clutch-coupling marries the ability of the Oldham coupling to compensate for misalignment with a proven slip clutch mechanism that maintains constant tension with no sudden shocks to damage fragile products. As well as tension control, the clutch provides repeatable cushioned torque for protection during overload conditions.

Seven sizes complete this new range, with bores from 12mm to 30mm and torque ratings up to 56Nm. Fixed-torque versions are also available to order. Follow the link for more information about the new Huco Dynatork clutch-coupling.
