How does a torque limiter work?<\/h3>\n

The LPB uses a ball-detent mechanism as its torque-sensing element. A set of hardened balls sits in conical seats machined into the drive hub. A spring pack holds the balls in position with a preset force that determines the trip torque. Under normal operating conditions, the balls remain seated, and the input and output flanges rotate together as a rigid coupling.<\/p>\n

 <\/p>\n

When the applied torque exceeds the set value, the force on the balls overcomes the spring preload, and the balls ride out of their seats. This disconnects the input from the output, and the flanges slip relative to each other. The slipping continues until the overload is cleared, at which point the balls drop back into the seats and the coupling re-engages. Re-engagement occurs at a defined angular position, which means the machine returns to the same mechanical reference after every trip.<\/p>\n

 <\/p>\n

The trip torque is adjusted by changing the spring preload. A sensor can be fitted to detect the slip event and send an electrical signal to the machine control system for logging or emergency stop triggering.<\/p>\n
