ABSTRACT:
A torque limiting apparatus is located between a power source and a driven apparatus. A number of breakable power transmission members connect a drive rotor to a driven rotor. The breakable members are fractured to disconnect the driven rotor from the drive rotor when the load applied by the driven apparatus exceeds a predetermined value. A promoting member is located near at least one of the power transmission members for promoting breakage when the load causes the driven rotor to rotate relative to the drive rotor. The breakable members are broken consecutively. The breakable members are not significantly affected by fatigue.
