The LPC torque limiter is a mechanism designed to absorb overloads in any type of machine, therefore they are mechanical “fuses”.
When the regulated torque is exceeded, a slip occurs between the chain sprocket, pulley, etc. and friction discs. The construction with helical springs gives it great regulation sensitivity and allows it to absorb wear without appreciable modification of the regulated torque.
Other applications of the LPC torque limiter, as a constant load element (retainers) or in single winding shafts, are possible as long as the heat generated is determined. Generally, low speed mechanisms lend themselves to this type of economical solution.
The nature of the nylon crown makes it more sensitive to heat. The possibility of using it as a continuous sliding element is more limited. In autonomous machines or where continuous slippage may not be detected by the operator, it is advisable to install an external speed detector that will act on an alarm or directly on the motorization.
