Harmonic Gearbox PG14

Harmonic Gear Operation Principle

Harmonic gear transmission is a novel mechanism that relies on elastic deformation for power transmission, breaking away from the traditional rigid component-based mechanical transmission models. It employs a flexible component for mechanical transmission, thereby achieving a range of special functions that are difficult to attain with other types of transmission.

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 accuracy, 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, 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 a smaller rotational inertia when using electromagnetic or disc wave generators.

6. Transfer 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 Scenario

Installation Matters

During installation, the alignment of the transmission center is crucial. When connecting the output and input shafts to the power and matching machinery, it is essential for the shafts to be aligned precisely, 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 from the left and right into the fixed screw holes. 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 start-up to ensure that 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 personal injury.

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 extended work, to avoid burns from high temperatures, wait approximately 10 minutes after shutdown before touching.
