BMG has been appointed distributor in southern Africa for the Vulkan Drive Tech product range, which includes couplings and braking systems. Included in the range are the Flexomax GBN maintenance-free couplings, with a maximum torque of 1288 kNm and shaft diameters up to 600 mm. These torsional flexible couplings are equipped with specially designed elastic elements which work in compression, allowing for maximum torque transfer, heat dissipation and product longevity.
The series is designed for applications such as low speed shafts on machinery driven by electric motors – even in harsh environments. These compact couplings allow for compensating axial, radial and angular misalignments and also protect the drivetrain from shock loads. The modular design enables the integration of brake discs, pulleys, shear devices and spacer shafts within the coupling. Radial removability of the coupling elements is possible, without having to move the connected machinery.
Vulkan’s vast range of highly engineered fixed speed and variable speed fluid couplings offers reliable functionality. The Flexomax GSND backlash-free couplings have been specifically designed for VFD high speed input shafts, offering multiple configurations to ensure coupling types meet all requirements. They eliminate the need for lubrication and allow radial removal of elements, without having to move machinery. Furthermore, the design incorporates air circulation slits to allow for a cooler element and thus a longer product life.
The shaft-to-shaft solenoid activated PSV–SP variable speed drain type fluid couplings are ideal for more demanding applications. These allow for larger heat dissipation in aggressive conditions, while the simple operating design reduces maintenance requirements.
