Description
Increased demands on drive systems require special concepts in highly flexible couplings. This demands include low idle-running speeds and silent operation of gearboxes in lower speed ranges. To meet this need, VULKAN has developed a multi-stage coupling with progressive stiffness characteristics. The TORFLEX coupling is exclusively intended for installation in bell housings and can be used where the gearbox input shaft has an external spline or oilpressfit. The positive characteristics are reached through the combination of two flexible couplings. For the first stage, VULKAN uses the wellknown VULKARDAN-E element, working under shear. The second coupling consists of four rollers, loaded in compression. The rubber material is resistant to abrasion and can operate at temperatures to 100° C. As torque increases, the rotation of the rubber rollers guarantees a soft, continuous change between the couplings. The highly flexible TORFLEX coupling, with a progressive torsional stiffness, is specially designed to combat gear noise in marine transmissions. |
