FLEXIBLE SHAFT COUPLING NOR- MEX H (TNM H) USE FOR PUMPING

DESCRIPTION:

The coupling Ringfeder Nor-Mex H (TNM H) is a torsionally elastic and puncture-proof claw coupling with a removable intermediate piece, mainly for the drives of pumps. It levels out angular, radial and axial shaft misalignments within defined ranges. The coupling transfers the torque via pressure loadable, elastic buffers of Perbunan (Pb) which are joined together as an intermediate ring. The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-tight and electrically conductive.

Both coupling halves are divided in two, which enables a radial installation and de-installation of the reduction sleeve. The de-installation measurement between the flange hubs allows the changing of the elastic intermediate ring or the dismounting of the bearing block of a centrifugal pump without moving the motor. The de-installation measurement between the flange hubs allows the changing of the elastic intermediate ring or the dismounting of the bearing block of a centrifugal pump without moving the motor. The coupling is usable in every sense of rotation and installation position.
