Harmonic Drive

Through big data modeling, simulation optimization and performance
verification, Han's Motion team realizes the optimal design of tooth profile,
breaks through barriers of experience accumulation and correction in
transmission design, and continuously improves and innovates in the parameter
performance, product structure, processing technology, material and appearance
of harmonic drive actuator. Through long-term technical experience, Han's cheap
harmonic drive has improved in product accuracy, service life, stability, noise
control and some other key technologies have reached the highest level in the
world, and the technical indicators are in the forefront.

At present, Han's harmonic drive has independently developed and produced 11
product series and more than 300 harmonic drive and newly upgraded to high
torque series, which improves product accuracy and service life, reduces
vibration and noise, with more stable and reliable performance. Our harmonic
drive covers the intelligent manufacturing industry and are widely used in
aerospace, communication equipment, robots, semiconductor processing equipment,
medical equipment, testing and analysis equipment and other fields.

Harmonic Gear Transmission Principle
The harmonic gear drive was invented by an American inventor, C· W· Musser.
user in 1955, It is a new type of transmission, which uses the elastic
deformation of flexible components for motion or power transmission. It breaks
through the mode of using the rigid component to realize mechanical drive, but
with a flexible component instead, thus obtaining a series of special functions
that other transmissions cannot reach. Its name comes from the deformation
process of the intermediate flexible component, which is a symmetrical
harmonic. Except that the former Soviet. Union called this kind of
transmission"Wave Transmission" or "Flexible Gear Drive", other countries like
America, England, Ger many, and Japan all called it "Harmonic Drive'.

Harmonic Gear Deceleration Principle
The principle of harmonic drive china transmission deceleration is to use the
relative motion of the flexible gear, rigid gear, and wave generator (mainly
the controllable elastic deformation of the flexible gear), to realize the
motion and power transmission. The elliptical cam in the wave generator rotates
in the flexible gear, causing the flexible gear to deform. When the flexible
gear teeth and the rigid gear teeth at both ends of the long shaft of the
elliptical cam in the wave generator enter the engagement, the flexible gear
teeth at both ends of the short shaft are disengaged from the rigid gear teeth.
For the teeth between the long shaft and the short shaft of the wave generator,
the half meshing state that is gradually entering into the meshing along the
different parts of the circumference of the flexible gear and the rigid gear,
is called meshing and the half meshing state that is gradually disengaging is
called engaging-out. The continuous rotation of the elliptical cam in the wave
generator makes the flexible gear deform constantly, which causes the teeth at
the flexible gear and rigid gear to shift between the states of engaging-in,
meshing, engaging-out, and disengagement, thus realizing motion transmission
from active wave generator to the flexible gear.

The Composition Of The Harmonic Gear Assembly
Rigid gear: A rigid internal gear, usually 2 teeth more than a flexible gear,
usually fixed onto the case;

Flexible gear: Thin-cup metal elastic part with gears on the outer ring of the
opening part. It deforms with the rotation of the wave generator and is usually
connected to the output shaft;

Wave generator: Consisting of an elliptical cam and a flexible bearing, usually
connected with an input shaft. The inner ring of the flexible bearing is fixed
on the cam, and the outer ring can be elastically shaped into an ellipse
through the ball bearing.

Harmonic Drive Wiki
With the rapid development of artificial intelligence, the artificial labor in
many areas are now replaced by robots. Although the cost of robot is very high,
it has created huge benefits for enterprises. Not only saves labor greatly, but
also works efficiently. The wide use of industrial robots can not only improve
the quality and capacity, but also be of great significance to ensure personal
safety, improve the working environment, reduce labor intensity, improve labor
productivity, save raw material consumption and reduce production costs.

Planetary Gear Set
In recent years, as long as we talk about industrial robots, they will connect
to the harmonic reducers. The industrial robot industry chain can be divided
into core parts, manufacturing, and system-integrated application. Among them,
the core parts are the basis of robot development and cost up to 72% of the
total cost of the robot. And the most important is the precision china harmonic
reducer (mainly harmonic drive and RV Reducer) which cost accounts for 36%.

Harmonic gear drive reducer is widely used in the field of industrial
automation because of their small volume, light weight, large torque, compact
installation, large transmission ratio, and high transmission accuracy. At
present, with the rapid development of industrial automation, the demand for
harmonic reducers has also increased a lot, and the supply continues to exceed
the demand.

Right Angle Gearbox
Han's Motion is also one of the manufacturers engaged in the R & D and
production of Harmonic Drive. At present, its products are at the forefront of
China manufacturers. It has independently developed 12 product series and 300 +
harmonic drives, which have been widely used in the automation industry.

Over the past few years, this small but very important parts for the robot,
account for about 30% of the total cost of the robot. The cost accounts for the
highest proportion of all key parts. However, the development in China is not
so smooth. The reducer is called "nail house" and "big trouble" in the
development of domestic robots. Moreover, foreign brands almost occupy the
high-end application field, and the development of domestic robots still has a
long way to go.
