What is a harmonic reducer?

A harmonic reducer is a type of gear mechanism used to achieve high torque and precision while maintaining a compact size. It operates based on the principles of harmonic drive, utilizing a flexible spline that deforms to engage with a rigid inner spline, allowing for significant speed reduction and increased torque multiplication. These reducers are commonly used in robotics, aerospace, and industrial automation applications due to their efficiency and low backlash. Their unique design enables smooth motion and high reliability in demanding environments.
