Shaft Coupling Description
TNM G 97 Pb82 (82 Shore A, Cast Iron, Formerly NORMEX) is a set of parts for assembling the RINGFEDER TNM shaft coupling.
RINGFEDER TNM is torsionally flexible, puncture-proof shaft coupling. It transmits 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.
This TNM coupling is of series G. One of the hubs is therefore composed of two parts – a flange hub and an outer claw ring, which is bolted to the hub. When replacing the worn flexible element, or disassembling and assembling, it is not necessary to move the individual machine parts, but it is sufficient to disassemble the two-piece hub.
TNM coupling hubs are made of gray cast iron as unbored. They are therefore supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.
TNM coupling can be used for both directions of rotation and each mounting position.
Formerly it was sold under the TSCHAN NORMEX designation.
Shaft Coupling Construction
- One-piece hub
- Flange hub
- Claw ring
- Pan-head screws with washers
- 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
- Max. finished bore: 280 mm
- Nominal torque of coupling TKn = 41,000 Nm / TKmax = 97,500 Nm
- Operating speed to nmax = 5000 1/min
