Couplings manufactured to orderIn addition to being available in the widest choice of materials to suit the application, Huco Dynatork reports that its Oldham can now be manufactured, in small batches from bar, in as little as two working days. This is a market leading response time. This customer benefit has been achieved through a combination of investment in flexible production technology and the adoption of lean techniques.
"This has given us ultimate manufacturing flexibility and one piece flow," explains managing director David Lockett. "And furthermore this improved service comes at no extra cost to the customer. It means minimal inventory and better business efficiency all round."
The Huco Dynatork Oldham is precision engineered throughout and comprises two hubs with inward facing tenons. These engage with matching slots spaced at 90° 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 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.
If severely overloaded the torque disc will break, acting as a mechanical fuse, thereby protecting associated equipment from damage. A replacement torque disc quickly restores the drive without the need to dismantle the drive system.
