ROTEX® Hub / KTR Systems

KTR SYSTEMS

ROTEX component 1a Positive-locking power transmission, permissible torque depending on the permissible surface pressure. Not suitable for backlash-free power transmission with heavily reversing operation.ROTEX® Standard - torsionally flexible jaw couplingThe original - renowned industrial standardThe torsionally flexible jaw coupling ROTEX Standard is an elastomer coupling with feather keyway and particularly low-cost due to its simple structure. For mounting the hubs of the elastomer coupling are simply pushed onto the shafts and axially fastened via setscrews.The coupling hubs of the flexible shaft coupling are available in the materials sintered steel, aluminium dieast, aluminium, cast iron and nodular iron.Our flexible elastomer couplings ROTEX Standard are provided with splines acc. to DIN and SAE as a standard.ROTEX couplings are suitable for universal use and applied as a flexible shaft connection in almost all ranges of general machinery and plant engineering.

ROTEX® star element for claw couplings / 64-98 Shore / KTR Systems

KTR SYSTEMS

The different degrees of hardness of the T-PUR-spider allow to adjust the level of damping and torsional stiffness of the elastomer coupling.ROTEX Spider / Elastomer Material :Our elastomer material T-PUR® (elastomer) 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 material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).The previous polyurethane spiders in the colours yellow, red and natural white with green marking of teeth continue to be available on request.Your Benefits:- Longer service life- Extended temperature range of more than 40 %- In the temperature ranges from +40° C to +90° C the temperature factor has been improved by up to 23 %- Maintaining all technical properties- Same price as the traditional spidersOTEX shaft couplings consist of two hubs (aluminium or steel) and a spider (elastomer ring / cam ring) made of T-PUR® (elastomer)

ROTEX® SPLIT hub / KTR Systems

KTR SYSTEMS

ROTEX SPLIT hub with feather keywaySplit hub made of sintered steel. Positive-locking power transmission with additional friction fit. The friction fit avoids or reduces reverse backlash. Surface pressure of the keyway connection is reduced.ROTEX® SH torsionally flexible coupling with split hubs / SPLIT hubsThe torsionally flexible jaw coupling ROTEX SH is an elastomer coupling with split hubs / SPLIT hubs (half shell coupling) easy to service and is characterized by easy assembly and disassembly.This design is also referred to as drop-our center design coupling, half shell coupling, clamping coupling, coupling with split hubs or elastomer coupling with split clamping hub.The hubs of the half shell coupling ROTEX SH have been split into two halves precisely, mechanically and reliably by "cracking". A rough surface with positive-locking connection ensuring an accurate fit of the two halves is generated. The contoured, rough cracked surfaces ensure ideal centering of the hub halves. The split hubs allow to assemble and disassemble the elastomer coupling radially via four screws without displacing the adjacent power packs. This makes the elastomer coupling with split clamping hub particularly easy to assemble and service.
