What is a Reaction Torque?
Reaction torque refers to the torque that is generated by other parts or supporting structures connected to an object. When it rotates, due to torque to maintain the balance and stability of the system.
Generation principle:
According to Newton’s third law (action and reaction), when an object is subjected to torque. An equal and opposite reaction torque will inevitably be generated.
It usually acts on the supporting structures connected to the original torque. Manifests as a reaction torque.
In a car engine, the crankshaft transmits the reaction torque to the engine body and frame through the connecting rod. And other mechanisms, while outputting torque to drive the wheels to rotate.
Impact and application:
It will affect the stability and durability of the mechanical system. Therefore, when designing a mechanical system, it is necessary to consider how to reduce or balance the impact of the reaction torque.
In some cases, the reaction torque can be used to achieve specific functions. Improve the efficiency of the system.
For example, in the design of a wind turbine, the reaction torque is generated by the wind. It can be used to enhance the output power of the generator by adjusting the angle of the blades.
How to Measure Reaction Torque?
The reaction torque sensor senses the change in torque by measuring the deformation of the elastic element.
This deformation causes the resistance value of the strain gauge to change. The change is converted into a current signal through a bridge circuit. Achieve accurate measurement of torque.
