Abstract
An overload safety device in an output gear box of a high speed turbine engine protects the output gears and shaft system of the turbine against damage due to instantaneous high loads imposed on the turbine as, for example, high loads due to out-of-phase paralleling of a generator. The device comprises interleaved friction discs normally compressed together under a predetermined load by a plurality of spring-biased clamping bars. When the torque load on the friction discs exceeds a predetermined amount, the discs will separate axially against the clamping bars whereby the torque overload is alleviated.
