Flange mechanical coupling JXL

pin and bushfor boatsfor ships

ATEX compliant 'JXL' torsionally resilient shaft couplings, of pin and bush design, comprise two fully machined steel flanges which are coupled via a series of drive pins and 'hytrel' flexible elements. The elements have the ability to absorb shock loads and dampen vibration. » The couplings do not produce static and do not sustain burning. » Maximum shaft diameters up to 400 mm. » Torques of 300,000 Nm. and » Speeds up to 11,000 rpm. can be accommodated. The 'JXL' range of resilient couplings is able to accept angular, radial and axial misalignment, they are torsionally resilient, non-lubricating and capable of operating between temperatures of –50°C and +105°C. The elements are flame resistant, anti-static and have NCB acceptance for use underground in coal mines number A2032. All ATEX compliant 'JXL' anti-static / flameproof couplings are capable of accepting a momentary overload of twice nominal torque. Couplings are selected on their ability to transmit torque between rotating shafts, with restricting factors being maximum speed and shaft diameter. (See selection notes below). Supplied in either shaft to shaft version or flange to shaft for drives that require a flywheel connection. Flanges or hubs can be supplied in carbon steel, stainless steel and other exotic materials. Torque in Nm (Newton metres) = Power (Kw) x 9550 Speed (RPM) Example 18.5 kW at 1500 rpm = 18.5 x 9550 = 117.783 Nm 1500
