Abstract
A torque transducer which is constructed so as to be protected from an overload includes a measuring axle which extends through a housing and a take-up axle which also extends through the housing in parallel with the measuring axle. The portion of the measuring axle within the housing includes two spaced apart gear wheels which are respectively engaged with backlash with gear wheels on the take-up axle, the gear wheels on the measuring axle being larger in diameter than the gear wheels on the take-up axle. When the measuring axle is subjected to excessive torque, such that the portion thereof within the housing twists sufficiently, the gear wheels on the measuring axle will engage with the gear wheels on the take-up axle to transfer the excessive torque to the take-up axle.
