Product catalog summary

Introduction
The DSM Modular Torque Limiter is designed for applications requiring up to 9,000 Nm of torque and a 140 mm bore. It is particularly suitable for high-speed and high-inertia environments, offering free rotation after disengagement without residual torque. The device is made from high-strength steel, ensuring reliability and maintenance-free operation.

Main Applications
The torque limiter is ideal for use in extruders, mills, the mining industry, heavy industry, earthmoving machines, and shredding/crushing machines. It provides protection against overloads, safeguarding both the product and the operational units of machines.

Advantages and Benefits
The DSM torque limiter protects against overloads, collisions, and external forces, preventing conveyor belt stoppages. It features a robust design with modular torque adjustment, allowing for quick and easy re-engagement.

Technical Specifications
The torque range is from 200 to 9,000 Nm with a maximum bore of 140 mm. The device is statically balanced, torsionally rigid, and allows for module replacement without removing other components. It includes integrated bearings for transmission support.

Dimensions
Dimensions vary by size, with specific measurements provided for sizes 0, 1, and 2. The device can be customized with finished bores, keyways, or locking assemblies.

Operation and Calibration
The DSM torque limiter operates by transferring torque through symmetrically arranged modules. In case of overload, the modules disengage, allowing free rotation. Calibration is performed manually with the device at rest, using an adjuster nut to set the torque value.

Additional Features
The device can be equipped with an overload detection ring and electromechanical switch or inductive sensor for monitoring and triggering alarms. It is protected from dust and dirt, ensuring long-term reliability.

Maintenance
The DSM torque limiter is maintenance-free, but torque calibration should consider factors like torque value, frequency of interventions, heat dissipation, rotational speed, and environmental conditions.

Order Example
An example order includes specifying the size, model, number of modules, finished bore, and torque requirements. The device is not self-supporting and requires proper shaft support with bearings.

Made in steel fully turned with high mechanical resistance. Ease of registration. Ease of manual re-engagement. Mounted on DSM devices for a torsionally rigid transmission. Disengaging with complete detachment between the driving and driven side. Available in two sizes. CALIBRATION ■ The key elements of the DSM module consist of the central piston (p) that will drive a hardened ball (s) into the location seat (t). Torque adjustment can be made also whilst the module is fitted to the torque limiter by the rotation of the hexagonal adjuster nut (r). Make sure that during the adjustment the fixing...
