What is the irreversible mechanical torque limiter LPU?
The irreversible mechanical torque limiter LPU is a mechanism designed to protect industrial machines by limiting the rotation torque in one direction only. When this torque is exceeded, controlled slippage occurs between components to prevent damage. In the opposite direction, it imposes no limits on the torque transmitted.
An invaluable guardian for industrial machines
Torque limiters are mechanical devices designed to protect industrial machines from overloads. They function like mechanical fuses, safeguarding the integrity of machinery and preventing costly breakdowns. One of the most prominent torque limiters is the LPU, known for its ability to limit torque in only one direction of rotation.
The essential difference
Tanto the LPU torque limiter as the LPC mechanical torque limiter are torque limiters, but they have a key difference. The LPU is irreversible, which means that it limits torque in only one direction of rotation, while the mechanical torque limiter LPC can do it in both directions. This feature makes the LPU particularly suitable for applications where it is essential to avoid turning in a specific direction.
Operation of the irreversible mechanical torque limiter LPU
When the torque in the direction of actuation is exceeded in a machine equipped with a the LPU torque limiter, a safety mechanism is triggered. This causes a controlled slippage between components, such as the sprocket, chain, pulley, or any other element involved. This controlled slippage protects the machinery from damage and prevents damaging overloads.
No limits in the opposite direction
One of the advantages of the LPU torque limiter is that, as opposed to torque limiting, it imposes no restrictions on the torque transmitted. This means that the machine can run smoothly when the load is within acceptable limits, ensuring continuous and efficient operation.
