Harmonic Drive Gearbox PG14

Principle of Harmonic Gear Operation

Harmonic gear drive is a new type of transmission mechanism that relies on elastic deformation to achieve motion. It breaks through the traditional rigid component model used in mechanical transmission by employing a flexible component for mechanical transmission, thereby obtaining 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, dual-stage from 3,000 to 60,000, and multi-stage from 100 to 140,000).

2. High return accuracy (due to numerous meshing teeth and low sliding speed of the tooth surfaces, resulting in high load-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 ordinary reducers, its parts are reduced by about 50%, and both volume and weight are reduced by over 1/3.

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

6. Transfer motion and power to sealed spaces using a sealed flexible-harmonic drive reduction unit, capable of driving mechanisms operating in high vacuum, corrosive, and other harmful environments.

Application Scenario

Installation Matters

During installation, it is crucial to ensure proper alignment of the drive center. When connecting the output and input shafts to the power source and matching machinery, the shafts must be aligned precisely with no eccentricity. Otherwise, it will significantly reduce the lifespan of the gearbox.

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

3. Recheck and verify the screws before startup to ensure 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 in operation to avoid 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 extended periods of work, to prevent burns due to excessive heat, wait approximately 10 minutes before touching the equipment after it has been turned off.
