Harmonic Gear Operation Principle
Harmonic gear drive is a novel transmission mechanism that relies on elastic deformation motion to achieve transmission. It breaks through the traditional mode of mechanical transmission using rigid components, employing a flexible component for mechanical transmission, thereby achieving a series of special functions that are difficult to attain with other transmission methods.
Advantages:
1. High transmission ratio (single stage harmonic drive ratio ranges from 50 to 300, dual stage ratio from 3,000 to 60,000, and multi-stage ratio from 100 to 140,000).
2. High return accuracy (due to a large number of meshing teeth and low sliding speed on the tooth surface, resulting in high bearing capacity, smooth transmission, high accuracy, and low noise).
3. Minimal backlash (tooth side clearance can be adjusted, achieving zero side clearance transmission)
4. Simple structure; compared to traditional standard reducers, it reduces parts by about 50% and volume and weight by over 1/3.
5. High transmission efficiency (not affected by large gear ratios); smaller rotational inertia can be achieved when using electromagnetic or disk wave generators.
6. Transfers motion and power to sealed spaces, utilizing a sealed flexible-hub harmonic drive reducer. Capable of driving mechanisms operating in high vacuum, corrosive, and other harmful environments.

Application Scenarios
Installation Matters
During installation, attention should be paid to the centering of the drive center. When connecting the output and input shafts to the power and matching machinery, the shafts must be precisely centered with each other; any misalignment will significantly reduce the lifespan of the gearbox.
2. During installation, hammering is not permitted. Typically, use tooling fixtures or press from the left and right into the fixed screw holes. Improper installation may result in an uneven sound and could lead to premature damage to internal parts.
3. Recheck and verify the screws before starting, ensuring all fasteners are securely installed.
4. During operation, it should initially rotate smoothly at low speed without vibration, noise, or oil leakage, which indicates normal operation.
Safety matters
Do not check the tightness of screws while the equipment is in operation to prevent personal injury.
Do not touch with your hands while in operation to prevent cutting your palm.
3. Perform inspections and repairs only after the machine has come to a complete stop.
4. After extended periods of operation, to avoid burns from excessive heat, wait approximately 10 minutes before touching the machine after shutdown.
