Which group Harmonic Drive (zero backlash) belongs to and how it is built
This subcategory covers components responsible for highly accurate torque transmission and speed reduction in robots, manipulators, and joint modules.
Harmonic Drive is a specialized strain wave gear valued in robotics for its high precision, very low backlash, and large gear reduction ratio in a compact form factor. It is widely used in the joints of industrial and humanoid robots, as well as manipulators with demanding accuracy requirements. Its compact construction enables the design of rigid, precise motion axes.
Strain wave gear design used in precision drive systems for robots and manipulators.
Basic physical properties of Harmonic Drive (zero backlash) — dimensions, weight and materials
Harmonic Drive (zero backlash) is a precision strain wave gear used in robotics wherever high positional accuracy, compact construction, and minimal backlash are required. Components of this type are widely used in robot joints, manipulators, robotic arms, axis drives, and positioning systems.
Key characteristics of this component class include very high precision, large gear ratios within compact dimensions, smooth operation, high repeatability, and suitability for applications requiring accurate motion control. In practice, a harmonic drive often appears as part of an integrated actuator or joint module alongside a motor, encoder, and controller.
