Abstract
A gearing unit with planetary gearing stages employs a load sensor and a clutch for disengaging drive through the gearing should the sensor detect overloading. The load sensor is in the form of a stationary pin provided with a strain gauge transducer easily accessible via a bore in a housing. The pin bears on a rotatable component of one of the planetary gearing stages to hold this component stationary during operation and is subjected to force proportional to dynamic loading on the gearing. The clutch serves as a brake to hold a rotatable component of another planetary gearing stage stationary and on release permits this component to rotate to interrupt the drive.
