SCF Series Automatic Clutch Torque Limiter

SCF Series Automatic Clutch Torque Limiter

This device interrupts the transmission of power when the torque exceeds the setting. To automatically re-engage the device, slow down or stop the PTO. This device is sealed, and no additional lubrication is required.The Automatic Clutch torque limiter is a radial cam-type that operates in only one direction of rotation (a reversed version is also available), ensuring torque transfer to a calibrated value, preset by a set of springs. Upon intervention, the Automatic Clutch limiter disconnects power transmission, canceling the transmitted torque to less than the residual pulsating torsional torque necessary for continuous reset. Reset occurs automatically when the transmission speed is reduced to a minimum value sufficient for the purpose after the cause of the overflow has been eliminated. The calibration torque value is preset at the factory and can be changed by the user after replacing the spring assembly.Overheating and vibrations during intervention are also reduced due to the minimization of residual moments. The compact design, low weight, use of plain bearings, and high-quality materials allow the device to be used even at speeds over 1000 rpm. Hardened, slotted profile to standard. Special designs are available upon request.-Standard hardened, slotted profiles;-Special designs are available upon request.

We also supply PTO Shafts & Agricultural Gearboxes

Agricultural equipment is prone to damage due to constant stress and load. It's important to know exactly what's causing the damage to identify a solution. Constant compression of a PTO shaft can damage connecting shafts and connections. In turn, a damaged tractor or implement will result. Fortunately, the average torque on an input shaft increases with ground speed. Using a PTO shaft on an agricultural tractor is one of the best ways to transfer mechanical power from the engine to the equipment. A PTO shaft is crucial for a weed eater, a tiller, or a bush hog. Proper PTO size is vital to protect both the tractor and the equipment.As the population continues to grow, so does the need for food. Agricultural machinery manufacturers have to look for new ways to meet this growing demand. With this in mind, selecting a quality replacement is essential to maximizing agricultural equipment's potential. Raydafon stocks an extensive selection of agricultural PTO shafts and gearboxes. We offer both North American and Italian-style PTO shafts. In addition, the agricultural gearbox is in a wide range. Feel free to contact us if you are interested.
