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 rigid component-based mechanical transmission model, utilizing a flexible component for mechanical transmission, thereby obtaining a series of special functions that are difficult to achieve with other transmission methods.

Advantages:

1. High transmission ratio (single-stage harmonic drive transmission 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 of the tooth surface, resulting in high bearing capacity, smooth transmission, high precision, and low noise).

3. Low backlash (tooth side clearance can be adjusted for zero side clearance transmission)

4. Simple structure; compared to traditional general reducers, its parts are reduced by about 50%, and its volume and weight are reduced by more than 1/3.

5. High transmission efficiency (not affected by large gear ratios); achieves smaller rotational inertia when using electromagnetic or disc wave generators.

6. Transfer motion and power to sealed spaces using a sealed flexible belt 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 aligning the transmission center. When connecting the output and input shafts to the power and matching machinery, the shafts must be aligned precisely with each other; any misalignment will significantly reduce the gear box's service life.

2. During installation, hammering is not permitted. Typically, use fixture clamps or press into place using the screw holes on either side. Improper installation may result in an uneven sound and could lead to premature damage to internal parts.

3. Recheck and verify all screws prior to startup to ensure that all fasteners are securely installed.

4. During operation, the product should initially 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 the machine is running to prevent injury to personnel.

Do not touch with your hands while in operation to prevent cutting your palm.

3. 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 approximately 10 minutes before touching the machine after it's turned off.
