Quick Summary

A transmission dynamometer is a device used in mechanics to measure the mechanical force or power transmitted by a rotating shaft without absorbing or using up the power during transmission. It functions by measuring torque, which is the turning force. This torque is generated by the load the prime mover or machine is carrying.12

Transmission dynamometers work by measuring the elastic twist of the shaft or using a special torquemeter inserted into the shaft. This allows for the measurement of power, which is the product of torque and angular speed. The shaft's speed is measured separately. This is distinct from absorption dynamometers, which create a restraint to the shaft's rotation to measure power.2

dynamometer
Power-measuring dynamometers may be transmission dynamometers or absorption dynamometers. The former utilize devices that measure torque, in terms of the elastic twist of the shaft or of a special torquemeter inserted between sections of the shaft. The torque is produced by the useful load that the prime mover, motor,…
