The precision coupling for an extreme shaft offset in a small D.B.S.E. (distance between shaft ends)
The Schmidt coupling offsets like no other coupling. Many engineers come across the familiar problem of shaft misalignments within driven shaft applications. In some cases the parallel offset of the shafts are above and beyond the capabilities of standard shaft couplings and can often result in punitive drive shaft length, or elaborate mechanical solutions to move driver and driven shafts in unison, to overcome the offset.
The Schmidt-Kupplung is a compact, torsionally stiff performance shaft coupling that compensates for variable parallel shaft offset without side loads during operation. The extreme shaft offset capability combined with a small D.B.S.E. (distance between shaft ends) makes the Schmidt-Kupplung quite unique. Interestingly, its modular construction allows both torque transmission and radial offset capacity to be optimized for each application. For example it is possible to accommodate a parallel shaft offset of 275mm in an overall shaft coupling length of 284mm! (Offset Plus V3300 series). No other shaft coupling design can provide the parallel shaft offset to overall length ratio.
Our classic design for extreme parallel offset. The Schmidt-Kupplung is a compact, torsionally stiff performance shaft coupling that compensates for variable parallel shaft offset without side loads during operation. The Schmidt-Kupplung is the ideal precision component for shaft connection in confined spaces. Through its modular construction both torque transmission and radial offset capacity can be optimised for each application.

The video demonstrates one of the innovative and precision shaft couplings known as the Schmidt-Kupplung®. It is a torsionally stiff performance coupling that compensates for variable parallel shaft offset, up to a staggering 275 mm, without side loads and in a very compact envelope.
The well-balanced design transmits torque without adding side loads to the drive. The Schmidt-Kupplung@ is utilised in many applications, in fact the design can be utilised in any transmission design where high torque, high shaft offset and small DBSE is present. The precision coupling transmits torque under constant angular velocity at all possible offsets and can transmit torque ranges from 35 Nm to 6610 Nm. 2D and 3D CAD format drawings are available for all model types.
Applications of the Schmidt-Kupplung®
Typical applications are:
- printing machines
- roll forming machines
- laminating machines
- corrugated paper machines
- paper making machines
No Side Loads
The Schmidt-Kupplung does not add side loads to the drive system.
The coupling design of three discs and two sets of links delivers exceptional torque in a small D.B.S.E length and outside diameter .
The well-balanced dimensions of the components and the large effective radius of the links give the Schmidt-Kupplung exceptional torsional stiffness.
The Schmidt-Kupplung is available in 3 basic series for various performance levels. There are three different shaft-hub connections available, those being a taper lock, standard bore or flange mount.
By choosing the appropriate shaft-hub connection, a drop-out installation of the coupling is possible.
Torque is transmitted via compression and tension of the coupling lever links. This well balanced system transmits torque without adding side loads to the drive. Moreover, the Schmidt-Kupplung will not transmit radial vibration from the drive to the driven shaft.
For over 40 years the Schmidt-Kupplung has been successfully used in diverse applications all over the world.
