Shear bolt clutches
Clutches with once-only cut-out function
Clutches with once-only cut-out functionDie The shear-bolt clutch is the simplest form of torque-interrupting clutch. If the permissible clutch torque is exceeded, a bolt is sheared off and power transmission thus interrupted.
The energy to be transmitted is converted into plastic deformation energy. The transmissible clutch torque is dependent on the effective radius of the cross-sectional area of the bolt, and its shear strength.
