Harmonic Gear Operation Principle
Harmonic gear drive is a novel transmission mechanism that relies on elastic deformation motion to achieve power transmission. It breaks through the traditional mode of mechanical transmission, which uses rigid components, by employing a flexible component for mechanical transmission. This enables it to achieve a series of special functions that are difficult to attain with other transmission methods.
Advantages:
1. High transmission ratio (single-stage harmonic drive transmission ratio ranges from 50 to 300, dual-stage ratio from 3000 to 60000, and multi-stage ratio from 100 to 140000).
2. High return accuracy (due to a large number of meshing teeth and low sliding speed of the tooth surface, resulting in high load-bearing capacity, smooth transmission, high accuracy, and low noise).
3. Minimal backlash (teeth side clearance can be adjusted, achieving zero side clearance transmission)
4. The structure is simple, with approximately 50% fewer parts than traditional general reducers, and both volume and weight are reduced by over 1/3.
5. High transmission efficiency (not affected by large gear ratios); smaller rotational inertia can be achieved when using electromagnetic or disc wave generators.
6. Transfer motion and power to sealed spaces using a sealed flexible-harmonic drive reducer, capable of driving mechanisms operating in high vacuum, corrosive, and other harmful environments.

Application Scenarios
Installation Matters
During installation, emphasis should be placed on centering 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 gear box's service life.
2. During installation, hammering is not permitted. Typically, use work holding fixtures or press into place using the screw holes, left and right. Improper installation may result in an uneven sound and could lead to premature damage to internal parts.
3. Recheck and verify the screws prior to startup to ensure all fasteners are securely installed.
4. During operation, the machine should first rotate smoothly at a low speed without vibration, noise, or oil leakage, which indicates normal operation.
Safety matters
Do not check the tightness of screws while in operation to avoid injury to personnel.
Do not touch with your hands while in operation to prevent cutting your palm.
3. During shutdown inspections, repairs and inspections should be conducted only after the machine has come to a complete stop.
4. After prolonged operation, to avoid burns from excessive heat, wait about 10 minutes before touching after the machine is turned off.
