1. High deceleration ratioSingle stage coaxial can achieve a high reduction ratio of 1/30 to 1/320. The structure and construction are simple, yet it can achieve a high reduction ratio device.
2. Small backlashHarmonic Drive ® Unlike meshing with ordinary gears, the backlash is extremely small, which is an indispensable element in the field of controllers.
3. High precisionMultiple teeth mesh simultaneously, and there are two 180 degree symmetrical gears meshing, so the influence of gear pitch error and cumulative pitch error on rotation accuracy is relatively even, achieving extremely high levels of position accuracy and rotation accuracy.
4. Less components and easy installationThe three basic components achieve a high reduction ratio, and they are all coaxial, so the kit is easy to install and has a simple design.
5. Small size and light weightCompared with previous gear devices, with a volume of 1/3 and a weight of 1/2, it can achieve the same torque capacity and reduction ratio, achieving small and lightweight design.
6. High torque capacityThe flexible wheel material uses special steel with high fatigue strength. Unlike ordinary transmission devices, the number of teeth meshing simultaneously accounts for about 30% of the total number of teeth, and it is in surface contact, which reduces the pressure borne by each gear and allows for high torque capacity.
7. High efficiencyThe sliding of the meshing part of the gear teeth is very small, reducing the power loss caused by friction. Therefore, while obtaining a high reduction ratio, high efficiency can be maintained, and the miniaturization of the driving motor can be achieved.
8. Low noiseThe meshing speed of the gear teeth is low, and the transmission of motion force is balanced, so the operation is quiet and the vibration is minimal.

The Harmonic Drive that produces this high-precision transmission ® The unique mechanism principle can be seen from its meshing.

• Wave generator
The elliptical cam is embedded with thin-walled ball bearings on its outer circumference. The inner wheel of the bearing is fixed on the cam, and the outer wheel undergoes elastic deformation through ball bearings. Usually installed on the input shaft.

• Flexible wheel
Metal elastomer components with thin-walled cup shape. The outer circumference of the opening is engraved with gears. The bottom of the flexible wheel (the bottom of the cup) is called a diaphragm and is usually installed on the output shaft.

• Steel wheel
Rigid circular component. The inner circumference is engraved with gears, which have two more teeth than flexible wheels. Usually fixed on the shell.

Harmonic DriveIt is composed of three components: harmonic generator, rigid wheel, and flexible wheel. Any one of these three components can be fixed to become a deceleration transmission or an acceleration transmission, or a generator, a rigid wheel drive, and a flexible wheel driven to become a differential mechanism.

The servo actuator is an optimized combination of a zero backlash harmonic reducer for precision control and a servo motor. Flat and hollow axis servo actuators are widely used in cutting-edge fields such as semiconductor liquid crystal production equipment, photovoltaic production equipment, medical devices, and work machine tools. The essence of a hollow servo motor is an engine that operates in a servo system. Its working mode is to control the operation of mechanical components, and its function is to help the motor achieve indirect speed changes. It can effectively control speed and achieve precise positioning by converting voltage signals into torque and speed to drive the controlled object. The speed of the hollow servo motor is controlled by its input signal, which can react in a short time and convert the electrical signal into angular velocity or angular displacement output on the machine shaft. It is mainly used in enclosed environments and has significant advantages over other motors in terms of speed, stability, comfort, and timeliness.
