The RFM Series Torque Limiters are precision-engineered safety devices designed to protect mechanical drive systems from overload and torque spikes. These limiters ensure reliable disengagement or slipping when preset torque levels are exceeded, safeguarding critical components such as motors, gearboxes, couplings, and driven machinery.
Designed for high accuracy, repeatability, and durability, RFM Series torque limiters are ideal for applications requiring continuous operation, high reliability, and minimal downtime.
Types of Operation (Based on Design)
Friction Type Torque Limiter:
• Slips when torque exceeds preset value
• Ideal for applications with frequent overloads
• Smooth torque transmission without interruption
Ball Detent Type Torque Limiter:
• Disengages instantly when torque limit is reached
• High accuracy and repeatability
• Suitable for precision machinery
Resettable Safety Coupling:
• Automatically re-engages after overload removal
• Minimize production downtime
Provides precise and repeatable torque settings, ensuring consistent protection of machinery.
Quickly reacts to overload conditions, preventing damage and minimizing downtime.
Depending on configuration, allows automatic re-engagement or controlled slipping during overload.
Easily adjustable torque values to suit different operational requirements.
Space-saving construction with high mechanical strength for industrial environments.
Simple design allows easy inspection, adjustment, and servicing.
High-quality materials and precision engineering ensure durability under repeated load cycles.
Components:
Input & Output Hubs:
• Precision-machined for secure shaft mounting
Torque Limiting Mechanism:
• Friction plates / spring-loaded balls / detent system
Adjustment Assembly:
• Allows setting of torque limit using calibrated mechanism
Housing / Cover:
• Protects internal components and ensures operational safety
Working Principle:
Under normal conditions, torque is transmitted through the limiter. When the torque exceeds the preset value, the limiter slips or disengages, interrupting power transmission. Once the overload condition is removed, the system either automatically resets or requires manual re-engagement, depending on the design.
