A harmonic gearbox, also known as a strain wave gear or harmonic drive, is a type of mechanical gear system that offers several advantages over traditional gearboxes. It consists of three main components: a wave generator (flexspline), a circular spline (outer ring), and a flexible spline (flexible inner ring). The interaction between these components produces a unique gearing mechanism that allows for precise motion control, compact design, high gear reduction ratios, and backlash-free operation.
- Nominal Output torque : 3.5Nm to 500Nm
- Backlash : less than 20 Arc-sec
- Available reduction ratio :1:50,1:80, 1:100, 1:120, 1:160
- High rigidity for stable precision work.
- SMD Harmonic Reducer also called as Strain Wave Gearbox is more compact and higher accurate.
- Applied in robot industry, especially for multi-axis robot joints.
