Harmonic Gearbox PG14

Principle of Harmonic Gear Operation

Harmonic gear drive is a novel transmission mechanism that relies on elastic deformation motion to achieve transmission. It breaks through the traditional pattern of mechanical transmission using rigid components, employing a flexible component to achieve mechanical transmission, thereby obtaining a series of special functions that are difficult to achieve with other transmission methods.

Advantages:

1. High gear ratio (single stage harmonic drive gear ratio ranges from 50 to 300, dual stage from 3000 to 60000, and multi-stage 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 (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 transmission 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 belt harmonic drive reducer, 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 auxiliary machinery, strict alignment between the shafts is required; any misalignment will significantly reduce the gear box's service life.

2. During installation, hammering is not permitted. Typically, use tooling fixtures or press in from the left and right of the 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 prior to startup, ensuring all fasteners are securely installed.

4. During operation, it 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 scratching your palm.

3. During shutdown inspections, repairs and checks should be conducted only after the machine has come to a complete stop.

After extended periods of work, to avoid burns from excessive heat, wait approximately 10 minutes after shutdown before touching.
