ROTEX® Standard 0 – 35,000 Nm / torsionally flexible jaw coupling

The original – renowned industrial standard
The torsionally flexible jaw coupling ROTEX Standard is an elastomer coupling with feather keyway and particularly low-priced due to its simple structure.
For mounting the hubs of the elastomer coupling are simply pushed on the shafts and axially fastened via setscrews.
Their flexible elastomer coupling ROTEX Standard is provided with splines acc. to DIN and SAE as a standard.
The torsionally flexible ROTEX couplings are suitable for universal use, and applied as a flexible shaft connection in almost all ranges of general mechanical and plant engineering.

Features

• torsionally flexible coupling for torsional vibration-damping power transmission
• Low-cost standard type
• Standard spiders made of high temperature-resistant T-PUR
• Splines acc. to DIN and SAE
• Complying with ATEX (acc. to EU directive 2014/34/EU)

Product Details
The coupling hubs of the flexible shaft coupling are available in the following materials:

• Steel
• Sintered steel
• Stainless steel
• Aluminium wrought products
• Aluminium diecast
• Cast iron
• Nodular iron

General Description
ROTEX shaft couplings consist of two hubs (aluminium or steel) and a spider (elastomer ring / cam ring) made of T-PUR®(elastomer). The different degrees of hardness of the T-PUR® spider allow to adjust the level of damping and torsional stiffness of the elastomer coupling.
The coupling requires enough mounting space allowing easy assembly/disassembly. The numerous types provided for maximum flexibility and meet with the different mounting requirements, through various types of hubs.

Function

• Jaw couplings ensure torsional vibration-damping power transmission and offset shocks generated by irregularly operating machines.
• In contrast to flexible couplings the connecting elements of which are stressed on bending and therefore to earlier wear, the flexible teeth of ROTEX couplings (elastomers) are subjected to compressive stress only. The benefit of the elastomer coupling thus is to withstand significantly higher loads.
• The elastomers deform with load and high speeds. Sufficient expansion space must be provided.
• All sizes of ROTEX jaw couplings have a maximum torsion angle of 5°. They can be mounted both horizontally and vertically.

Material
Their elastomer material T-PUR® is resistant to higher temperatures and has a considerably longer service life than common polyurethanes. From a visual point of view we marked the T-PUR® (elastomer) material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).
