Overload protection and torque limiters

Easily secures equipment against torque peaks

Overload couplings and torque limiters

What is an overload coupling?

In order to avoid considerable consequential costs in the event of undesired torque peaks, drive technology requires overload protection in the form of a safety coupling or a torque limiter. These safety couplings disconnect the connection between the two shafts above a certain torque, resulting in decoupling. This reliably prevents an overload of the drive and helps to protect your equipment or machinery.

Why is it important to install torque limiters?

Overload protection, also called torque limiters or overload couplings, are used to immediately interrupt an overload in the drive chain and thus reliably protect your machine. As soon as the torque drops below the set value again, input and output are automatically reconnected.

How does a torque limiter work?

The torque is set and monitored by the integrated torque spring. Torque limiters are particularly characterized by the fact that they are maintenance-free and do not require recalibration. When operating with two shafts, the element can also be used as a flexible coupling. Even use in oil is possible.

What are the different types of overload couplings?

The TT(01) model connects two shafts together, while the TT(03) model is suitable for belt pulley operation. For machine applications with high speeds up to 1800 rpm with shaft-shaft or shaft-hub connection, the backlash-free TT(01) or TT(03) torque limiter is perfect for torques between 0.2 to 200 Nm. In addition, parallel and axial offsets are compensated in your application.

The DMB torque limiter is particularly suitable for use with hand-operated assembly tools or as an attachment to hand levers. With the standardized inch connections, this is perfectly designed for recurring assembly work in the torque range of 3-30 Nm or 30-90 Nm. Depending on the size, our DMB torque limiter comes with 3/8″ or 1/2″ internal and external square drive and is ready for immediate use.

Where are torque limiters used?

Torque limiters are used wherever a certain torque must not be exceeded. For example, when it comes to safeguarding the torque of a machine tool or a paper processing machine. Our products are also used in shipbuilding and aviation or in railroad track construction as well as in textile, plastic and cardboard processing machines and many other industries.
