2. Learn more about TNM Normex E Ringfeder Germany shaft coupling:

The Ringfeder TNM E coupling (Elastomer Jaw Couplings TNM E) is a puncture-resistant torsion elastomer coupling. It balances angular, radial, and axial deviations within defined limits. The coupling transmits torque through resilient, load-bearing neoprene (Pb) buffers in an intermediate ring. The medial elastic ring can cushion impacts and torsional vibrations; It is oil resistant and conductive. The coupling can be used at any rotation angle and installation position.

3. Structural features of TNM Nor-mex E Ringfeder Germany shaft coupling:

- Nor-mex E coupling (Elastomer Jaw Couplings TNM E) is designed with 2 hubs and 1 damping rubber with different standard hardness: Pb72 and Pb82

- TNM Nor-mex E shaft coupling flexible in terms of torsion, axial, radial, and axial misalignment compensation

- Suitable for working in environments with temperatures from -30 degrees Celsius to +100 degrees Celsius

- The elastic ring can only be replaced by moving a part of the machine to be coupled

- Nor-mex E shaft coupling includes 18 sizes

- Inner diameter: d1 : 19 - 230 mm; d2 : 19 - 230mm

- Outer diameter D1 : 50 - 575 mm

- Overall length L: 52 - 488 mm

- Rotation speed: 1,800 - 5,000 rpm

- Torque Pb72: 13-27,000 Nm; Pb82 : 20-41,000 Nm

- Rubber shock absorbers can impact and torsional vibrations; It is oil resistant and conductive.

- Coupling can be used at any rotation angle and installation position

4. How to properly install TNM Nor-mex E Ringfeder Germany shaft coupling:

Before installing TNM E coupling, attention should be paid to:

- Risk of injury

- Disconnect the drive before doing any work on the coupling

- Protect the inverter from unintentional restart and rotation

- Improperly tightened bolts can cause serious personal injury and property damage

- To comply with accident prevention regulations, you need to protect all free-rotating components with permanently installed shields/cases against unintentional contact and falling objects

- To avoid sparks, covers of joints used in explosive atmospheres must be made of stainless steel.

- At a minimum, the housing shall be designed to prevent dust from accumulating in the coupling

- Make sure that the speed, torque, and ambient temperature are as stated in Chapter 6

'Technical data' should not be exceeded.

- Do not exceed the maximum allowable hole diameter.

- Check that the shaft-drum connections transmit the operating torques that occur safely.

- The standard tolerance of TNM couplings for finishing holes is H7.

- Standard keyways according to DIN 6885, sheet 1.

- Check the dimensions and tolerances of the shaft, shaft hole, key, and keyway.

- Set screws as required.
