GENERAL INFORMATION TORQUE LIMITERS SINGLE POSITION MULTI-POSITION LOAD HOLDING GENERAL INFORMATION R+W safety couplings operate as spring loaded ball-detent clutches. They protect drive components (e.g. motors, transmissions, and spindles) from damage caused by machine crashes and other forms of overload. The torque is transmitted by hardened balls (4) loaded into conical detents (5). The balls are loaded into the detents by the spring disc system (2) across the switch plate (3). Note: Automatic re-engagement only occurs at low speed. The disengagement torque is continuously adjustable via the...

FULL DISENGAGEMENT FULL DISENGAGEMENT In the full disengagement version the spring system (7) snaps over center, eliminating residual force on the balldetent system. This causes a complete separation at overload, allowing shafts to spin freely until they are stopped. engaged e-engagement must be performed manually R (see figure at right). BALL-DETENT CLUTCHES ARE THE SAME DESIGN IN THE SK AND ES2 SIZES From size 60 and up a recess is included in the torque adjustment nut, allowing for 2 levers to be used in a self contained fashion, as shown in the figure on the right. ATEX CERTIFIED COUPLINGS...

GENERAL INFORMATION TORQUE LIMITERS BEHAVIOR AND CHARACTERISTICS R+W safety couplings work exclusively with a disc spring system with a special characteristic. Prior to the the torque adjustment nut coming into contact with the disc springs and applying pressure (1) no torque transmission is possible. Once the spring is loaded, the active range of the spring system had been reached, with the spring rate declining as further compression takes place, both prior to, and during disengagement (2). Once completely depressed, the spring system is rigid (3). SPRING CHARACTERISTIC special design TKN max...
