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® 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
