Shaft Coupling Description

TNM 112 Pb82 - Elastic Ring (82 Shore A, Black, Rubber, Formerly NORMEX) is a part designed for RINGFEDER TNM shaft couplings.

RINGFEDER TNM are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a rubber element. They transmit torque through pressure-stressed elastic buffers connected to each other in an intermediate ring, which absorbs shocks and torsional vibrations. This element is oil resistant and electrically conductive.

Formerly they were sold under the TSCHAN NORMEX designation.

Shaft Coupling Construction

RINGFEDER TNM E Coupling Construction

  1. One-piece hubs
  2. Elastic ring

Shaft Coupling Fields of Use

RINGFEDER TNM (formerly TSCHAN NORMEX) elastic couplings are designed for the highest requirements in a wide range of industries, especially for compressors, pumps, conveyors and many other machines.

Robust design and excellent damping properties guarantee users maximum operational reliability, especially in applications with significant shock, alternate or vibration loads.

Shaft Coupling Characteristics

  • Compensates for angular, parallel and axial shaft misalignments of the connected machines
  • Elastic elements of two different Shore hardness are available
  • Elastic elements operate in temperature ranges of −30 °C to +100 °C
  • Replacement of elastic elements without axial movement of the coupled machines (principle of the multi-part design)
  • Max. finished bore: 280 mm
  • Nominal torque of coupling TKn = 41,000 Nm / TKmax = 97,500 Nm
  • Operating speed to nmax = 5000 1/min
