 | Flaton Clutches High Torque Clutches for Low Speed Applications |
|
|
|
 Flaton Clutches have long been recognized for their high torque capabilities in low speed applications. Flaton's compact designs have a high degree of repeatability and are available in a variety of configurations.
When a power transmission system is subject to sudden or excessive loads, Flaton Clutches prevent twisted shafts and broken gears, sprockets and chains. Once the unit is adjusted and locked, the clutch will slip automatically if the load exceeds the predetermined torque setting. When the overload is relieved, the clutch resets automatically and is ready to carry a normal load once again.
Flaton Clutches operate both clockwise and counterclockwise and function efficiently at moderate and low speeds, to less than one rpm. |
 Operating Mechanism
The operating principle is the same for all types of Flaton Clutches. A friction cone is fitted into the threaded and taper-bored housing, and this integral cone is backed up with a thrust bearing. An adjustment nut forces a rubber pressure ring against the bearing to hold the friction cone at the proper tension to transmit the required torque. The adjustment nut and locking mechanism allow for 40 standard torque settings. The amount of torque can be increased or decreased by tightening or releasing the adjustment nut as conditions require.

|
Clutch Location Flaton Clutches are designed to offer high torque capacity and compact size. The recommended clutch location is, therefore, at the high torque (low speed) area of the transmission train. Locating the clutch on the slow side of the transmission minimizes heat generation and results in longer wear life and minimal maintenance. |
