ROTEX® Hub / KTR Systems (Part Numbers - CAD Download)

Click on this image to zoom in.

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® Flexible Jaw Couplings

Hub Types

Due to the numerous applications of ROTEX® for many different applications and mounting situations, this coupling system is available with various hub types. These types mainly differ in that they offer either positive or frictionally engaged connections, but mounting situations like, for example, gear shafts with integrated transmission cams or similar applications are covered, too.

	Type 1.0 hub with feather keyway and setscrew Positive locking power transmission, permissible torque depending on the permissible surface pressure. Not suitable for backlash-free power transmission with heavily reversing operation. Type 1.1 hub without feather keyway with setscrew Non-positive torque transmission for crimp and glued connections. (No ATEX-release) Type 1.3 hub with spline bore (see page 20)			Type 2.0 clamping hub single slotted without feather keyway Frictionally engaged, backlash-free shaft-hub-connection-. Transmittable torques depending on bore diameter (see page 34). (For ATEX category 3 only) Type 2.1 clamping hub single slotted with feather keyway Non-positive torque transmission for crimp and glued connections. (No ATEX-release) Positive locking power transmission with additional frictionally engaged condition. The frictional engagement avoids or reduces the reverse backlash. Surface pressure of the keyway connection is reduced. Type 2.3 clamping hub with spline (see page 29/30)

	Type 4.2 hub with CLAMPEX® clamping set KTR 250 Frictionally engaged, backlash-free shaft-hub-connection for the transmission of average torques. Type 4.1 for CLAMPEX® clamping set KTR 200 type 4.3 for CLAMPEX® clamping set KTR 400 Frictionally engaged, backlash-free shaft-hub-connection for the transmission of high torques.			Type 6.0 clamping ring hub (see ROTEX® GS series) Integrated frictionally engaged shaft-hub-connection for the transmission of higher torques. Screwing on elastomer side. For details about torque and dimensions see page 29. Suitable for high speeds. Type 6.5 clamping ring hub (see ROTEX® GS series) Design like 6.0, except for clamping screws externally. As an example for radial disassembly of intermediate pipe (special design).

	Type 7.5 clamping hub type DH without feather keyway for double-cardanic connection Frictionally engaged, backlash-free shaft-hub-connection for radial assembly of coupling. Transmittable torques depending on bore diameter (For ATEX category 3 only) Type 7.6 clamping hub type DH with feather keyway for double-cardanic connection Positive locking power transmission with additional friction fit for radial assembly of coupling. The frictional engagement avoids or reduces the reverse backlash. Surface pressure of the keyway connection is reduced.			Type 7.8 clamping hub type H without feather keyway Frictionally engaged, backlash-free shaft-hub-connection for radial assembly of coupling. Transmittable torques depending on bore diameter (For ATEX category 3 only) Type 7.9 clamping hub type H with feather keyway Positive locking power transmission with additional friction fit for radial assembly of coupling. The frictional engagement avoids or reduces the reverse backlash. Surface pressure of the keyway connection is reduced.

	Type 7.0 SPLIT hub without feather keyway Split hub made of cast iron. Frictionally engaged, backlashfree shaft-hub-connection-. Transmittable torques depending on bore diameter (For ATEX category 3 only)			Type 7.1 SPLIT hub with feather keyway Split hub made of cast iron. Positive locking power transmission with additional frictionally engaged condition. The frictional engagement avoids or reduces the reverse backlash. Surface pressure of the keyway connection is reduced.

	FNN hub Coupling hub to be connected to an attachment such as brake drum, brake disk and fan.			SD hub shifting hub Coupling hub for separating or switching on the driving/ driven machine with standstill of the machine. Can be combined with slip ring and shiftable linkage.

	TB1 hub/TB2 hub Coupling hub for taper clamping bushes. TB1 screwed on cam side. TB2 screwed externally.			Type 3Na + 4N Driving flange with flange type K For type AFN and BFN: With type AFN the spider can be replaced while being assembled without having to disassemble the driving and driven side.

	Mitnehmerflansch Ausf. 3b Driving flange to connect to customer’s component. Abmessungen siehe Seite 38			Mitnehmerflansch Ausf. 3Na Driving flange to connect to customer’s component. Abmessungen siehe Seite 38
