The primary function is to protect machinery from damage by limiting the maximum torque transmitted through a drive system. When torque exceeds a preset threshold, the limiter slips or disengages, interrupting torque transmission to prevent overload damage to gears, shafts, motors, or workpieces.
Selection is based on the application's torque requirement, which should fall within the rated torque range of 10–5000 N·m. Consider the adjustment range (50–100% of rated torque), maximum speed (3000–6000 rpm), operating temperature (-20 to 80°C), and shaft diameter (10–100 mm). Always verify these parameters with the manufacturer for your specific model.
Regular inspection of friction surfaces and mechanical parts is recommended. Check for wear, contamination, and proper torque setting. Service life is typically 10,000–50,000 cycles, depending on load and maintenance. Follow the manufacturer's guidelines for reset procedures after an overload event.
Common types include friction-type, shear-pin, and ball-detent. Friction-type limiters slip when torque exceeds the threshold, while shear-pin and ball-detent types disengage completely. Each type has different reset characteristics and suitability for various applications.
