Harmonic Gearbox PG20

Harmonic Drive Principle

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

Advantages:

1. High transmission ratio (single-stage harmonic drive 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 load-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 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 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-disc harmonic drive reducer, capable of driving mechanisms operating in high vacuum, corrosive, and other harmful environments.

Application Scenarios

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, the shafts must be aligned precisely with each other, without any misalignment. Otherwise, it will significantly reduce the lifespan of the gearbox.

2. During installation, hammering is not permitted. Typically, use tooling fixtures or press into place using fixed screw holes from left to 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, 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 cutting your palm.

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

4. After extended periods of operation, avoid burns from high temperatures; wait about 10 minutes after shutdown before touching.
