SYNTEX® is a safety system operating with positive locking suitable for torques up to 525 Nm. The component transmitting the torque is a punched disk spring (protected by patent). The design of the coupling ensures short reaction times with high repeating accuracy.  Due to the special design it is easy to integrate the coupling in the drive.

Punched disk spring

SYNTEX® is an overload system with positive operation.

The punched disk spring serves as the component for torque transmission (registered patent).

Ratchet design DK

If the torque set is exceeded, there is a relative movement between the driving and driven side. The transmittable torque is decreased to a minimum.

The balls leave the indentations of the disk springs. After eliminating the overload, the balls engage automatically with the next following ball indentation of the disk springs.

Synchronous design SK

If the torque set is exceeded, there is a relative movement between the driving and driven side. The transmittable torque is decreased to a minimum.

The balls leave the indentations of the disk springs. After eliminating the overload, the balls re-engage automatically with the disk springs after a rotation of 360°. Driving and driven side are always placed in the same position to each other (other degrees of re-engagement, for example 180°, are also possible).

Information about selection of torque limiters

To make sure that the torque limiter does not yet release with torque peaks related to the process, the switching torque of the coupling should exceed the maximum operating torque by at least 30 % (see diagramme).

Torque limiters and overload systems which re-engage automatically should only be used with a reduced speed for higher release torques. Frequent or longer slipping or ratching increases the wear of the torque limiter.

After the torque limiter has disconnected driving and driven side in case of overload, it may take some time before the drive comes to standstill because of a high inertia in the drive train. This may cause higher wear on the torque limiter and the overload system re-engaging automatically. That is why we recommend the use of the overload system KTR-SI as an idle rotation type for drives with big inertias or with higher speeds.

We basically recommend electronic monitoring of the torque limiters in order to protect the drive in case of overload.

We will be pleased to support you with technical questions and with the selection of torque limiters. For that purpose we dispose of the latest simulation and calculation programs. Here the following fact applies: The more detailed the data, the more accurate are the calculation results.
