Understanding Strain Wave Gears

Strain wave gears, also known as harmonic drive gears, are unique mechanical assemblies that convert rotary motion into precise movement. Their structure typically consists of three main components—an input cam, a flexible spline, and a circular splined output. This design allows for high gear ratios in a compact space, making them particularly appealing for robotic applications, automation, and various industrial sectors.

Key Characteristics of Strain Wave Gears:

• High torque density
• Zero backlash
• Compact design
• Excellent precision
