Model FRP - 2/4 Discs Torque Limiter
From Safety Devices
2/4 DISCS TORQUE LIMITER WITH HELICAL SPRINGS AND FREE WHEEL, WITH FOOT MOUNTING. It’s a safety device that integrates the functions of clutch discs and freewheel, with foot mounting. The limitation of the torque to the calibration value, adjustable by changing the height of compression of the helical springs, takes place while maintaining the power transmission, with the components of the clutch sliding over two or four friction discs.

Characteristics and functioning
The torque limiter FRP is a safety device that integrates the combined functions of clutch discs and freewheel, with foot mounting.
The limitation of the torque to the preset value, which occurs while maintaining the transmission of power, is guaranteed by the slippage of the clutch components on discs of special material (asbestos-free). The value of torque setting can be adjusted by changing the height of compression of the helical springs. It’s available with two or four friction discs.
Special design on request.
Application
The torque limiter FRP is recommended to protect the driven machine by accidental overloads, without the need for interruption of torque. The intervention of the device produces heat, so it is advisable to reduce the slipping time in order to avoid excessive overheating that can degrade device performance.
It’s particularly suitable for power transmissions of machines with high rotational inertia (for example, round balers) because, being associated with a freewheel, in addition to absorbing the torque peaks of startup also avoids the return torque during deceleration or stop. The new grease seal and additional ball bearing help to limit the wear of the freewheel.
Maintenance
Before long periods of inactivity we recommend to unscrew the nuts that compress the springs as the pressure on the discs in wet environments causes sticking of the discs themselves. The setting can be modified by adjusting the nuts to change height springs.
Lubricate the clutch each eight hours using the greaser.
