Which group Harmonic Drive CSD-25-2A belongs to and how it is built
Gearboxes & Transmission is a subcategory of mechanical components responsible for changing gear ratios, transmitting torque, and matching drive characteristics to application requirements. It includes planetary and harmonic gearboxes, reducers, transmission elements, and other mechanical assemblies used in joints, manipulators, and robotic drives. These components are critical to force output, motion precision, and dynamic performance.
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.
