This category introduces the principles, technical information, product lineup, tooth profile, transmission accuracy, backlash, wave generator, and product drawings of strain wave reducers.

The Harmonic Drive Gearbox, also known as a Strain Wave Gearbox, is irreplaceable in applications requiring high precision, compact size, and low load.It is widely used in collaborative robots, servo systems, precision positioning and scanning equipment, aerospace, defense, and other high-precision systems.Thanks to its zero backlash, high reduction ratio, lightweight design, high positioning accuracy, and excellent repeatability, the harmonic drive has become an essential precision transmission solution in many advanced fields.

The harmonic drive reducer is a high-performance reducer featuring a compact structure, large transmission ratio, light weight, minimal backlash, and high transmission accuracy. It is widely used in high-precision fields such as industrial robotics, medical equipment, aerospace, and intelligent manufacturing. As a key core component of industrial robots, its performance directly affects motion control accuracy, operational stability, and energy efficiency. The top-hat type harmonic drive reducer is developed based on the conventional harmonic drive reducer, with enhanced rigidity and extended service life.

The FHG-SJ series strain wave gearbox is engineered for high-torque and heavy-load applications, featuring compact axial dimensions compared to conventional reducers. It incorporates a top-hat style flexspline and an integrated cam wave generator, where the cam shaft bore is customizable to match specific motor models. The input shaft directly interfaces with the wave generator’s inner bore via a keyway connection. This series typically employs a fixed flexspline end and an output circular spline end configuration.
