Harmonic Gearbox PG14/PG32

Principle of Harmonic Drive Gear Operation

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 instead. This approach enables a series of special functions that are difficult to achieve with other types of transmission.

Advantages:

1. High transmission ratio (single-stage harmonic drive transmission ratio ranges from 50 to 300, double-stage from 3000 to 60000, and multi-stage from 100 to 140000).

2. High return accuracy (due to numerous 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, achieving zero side clearance transmission)

4. Simple structure; compared to traditional general 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 disc wave generators.

6. Transmits 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

1. During installation, emphasize the alignment of the drive center. When connecting the output and input shafts to the power and auxiliary machinery, it is crucial that the shafts align perfectly; any misalignment will significantly reduce the gear box's service life.

2. During installation, hammering is not permitted. Typically, use tooling fixtures or press from the left and right into the screw holes. Improper installation may result in an irregular sound and could prematurely damage internal parts.

3. Recheck and verify the screws before starting, ensuring all fasteners are securely installed.

4. During operation, the machine 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 in operation to avoid injury to personnel.

Do not touch with your hands while in operation to prevent hand cuts.

3. Inspections should be conducted only after the machine has come to a complete stop.

4. After prolonged operation, to prevent burns from excessive heat, avoid touching the equipment for about 10 minutes after shutdown.
