Japan: HDS, provided to “Hayabusa2”: Speed reducer for precision control
-A great deal of attention in space development, Japan’s “great company”-
World Space Exploration:
The United States and Russia have led the world in space development.
American Space Exploration:
Since the 1990s, the reduction of the US space development budget has become remarkable.
In 2011, after the Space Shuttle program was completed, NASA was using a Russian rocket.
In the future, NASA plans to use private spacecraft to keep costs down and maintain space development.
Japanese Space Development:
Another advance in space development is planetary exploration, with Japan leading the world.
In the field of spacecraft development and space passengers, the military will rise to the United States and China.
On the other hand, Japan is a leader in planetary exploration in scientific research.
JAXA project:
JAXA oversees the project
With NEC and Mitsubishi Heavy Industries playing a central role
The developed “Hayabusa2”
Parts from many Japanese companies are used.
Featured company is Harmonic Drive Systems (HDS)
HDS:
Reducers, bearings, etc.
Control equipment combined with a motor,
Total motion control,
As the world’s only one company, providing precision equipment.
Industrial robots
Surgical robots, etc.
Contributes to higher precision and lighter weight of various mechanical devices.
Indeed, it is indispensable for planetary explorers that require light weight and high accuracy.
Japanese planetary probe “Hayabusa2”:
HDS’s “Harmonic Drive” reducer has been introduced in the first and second generation “Hayabusa”.
Subaru Telescope on the Big Island of Hawaii:
In addition, HDS products such as Harmonic Drive are also used in the “Subaru Telescope” on the Big Island of Hawaii that observed “Hayabusa2”.
Return of “Hayabusa2
Hayabusa2 1 week to return.
Along with the results, We would like to pay attention to the growth of HDS.

2020/09/30 — NASA’s Mars exploration rover, which has already been launched, uses 19 harmonic reducers per unit.
Shipped from 1983 for space applications.
Since the wave gear device can obtain a high reduction ratio in one stage, it is suitable for space equipment that requires weight reduction.
Driving a rotating shaft to point the solar array paddle toward the sun,
Drive shaft applications for directing high-gain antennas to the earth,
For driving joints of space robots, etc.
Strain wave gearing has a wide range of uses in the space field. Also used to drive the axles of exploration rover traveling on celestial bodies
