What is a torque limiter or a safety clutch?

A torque limiter is a mechanical drive element that is used in machines and systems to protect them from damage caused by overload. It enables the drive components to be disconnected if a predefined torque value is exceeded.

How does a torque limiter work?

The function of a torque limiter is based on the principle of friction. E.g. during normal operation, the input and output are connected to each other via friction linings and transmit the torque. However, if a predefined torque is exceeded, the friction linings slip and separate the connection. This prevents costly damage, repairs and downtime.

Where are torque limiters and safety clutches used?

Torque limiter are used in many industries and drive systems. They are used to prevent expensive damage to machines and systems due to overload and to ensure operational safety. The toothed SecMatic overload clutch is used, for example, to protect extruder screws from damage.

What are the advantages of torque limiters?

Torque limiter or safety clutches protect machines and systems from overload damage, thereby reducing downtime and repair costs. They also offer a simple and cost-effective way to improve machine safety. In addition, they enable a quick and easy resumption of operation after an overload situation.

How to choose the right torque limiter?

Selecting the right torque limiter depends on various factors, such as the required torque range, operating speed, environmental conditions and the specific requirements of the application. When selecting this complex drive element, it is advisable to seek expert advice.

Torque limiters from Mönninghoff: Because every application needs a different safety device

The selection of the suitable torque limiter always depends on the specific application as well as on torque, speed, moment of inertia, unbalance and other criteria. The design engineers at the Maschinenfabrik Mönninghoff will be pleased to adapt this important element for you up to a fully automatable, electromechanical solution.

As an expert in drive technology and as a manufacturer of clutches and couplings, Mönninghoff offers various operating principles:

SecMatic torque limiters: Our SecMatic torque limiters are maintenance-free torque limiting clutches with a diaphragm spring as central element. They offer a form-fit torque transmission with minimum reaction time. The switching process is extremely precise under both static and dynamic loads. The overload torque can be reproduced very well due to a special coating of the teeth. The SecMatic clutches have been specially developed to provide maximum safety with very easy integration due to their compact design.

Electromagnetic clutches: Electromagnetic clutches are can also be used as overload clutches. Compared to adjusted, mechanical clutches, they offer the advantage that the torque can be flexibly adjusted by regulating the voltage and current supply. Since movements in the limit range are also excluded, the overload clutch operates wear-free. The uncompromising safety and reliability, the simple control via direct current as well as the optimized magnetic flux guidance make the electromagnetic overload clutch an integrated, easy-to-install system solution even for extraordinary loads such as extreme temperature.

Multiplate torque limiter: Multi-plate torque limiter, on the other hand, offer high torques in a small installation space and can be used both in dry and oil running, whereby a special friction lining ensures low wear. The transmittable torque can usually be infinitely adjusted in the range of 80 to 110% of the nominal torque. The set torque is maintained even in case of overload.

A wide range of operating principles, materials and designs allow the construction to be extremely varied depending on your requirements. Together with our customers we develop extraordinary solutions for extreme operating conditions with the absolute focus on safety. We guarantee a long service life and high functional reliability of our systems.
