Introduction Story

The World of Motion Control Transformed by a Single Invention- Creation of a product that inherits the heritage of a gifted inventor -C.W. Musser, inventor of HarmonicDrive®

A Constant Search for Total Motion Control
Musser Heritage Room
The Musser Heritage Room was opened in October 2006.

We have been establishing total motion control by using the high-precision machining and control
technologies we have acquired over many years of operation. To maximize the performance ofHarmonicDrive®, we continue our efforts to improve it further toward higher levels of motion technology.

Musser’s wave-motion gearing mechanism was originally called “Strain-wave
gearing” and was patented under that name.
Subsequently in Japan, Harmonic Drive Systems Inc. succeeded in commercializing
the technology.
The technology today is generally referred to as a “wave-motion gearing
mechanism,” while the term HarmonicDrive® is a registered trademark thatapplies exclusively to the products manufactured by Harmonic Drive Systems Inc.
This trademark is registered not only in Japan, but also Taiwan and South Korea.

R Series

CSF/CSG Series

CSD Series

Our HarmonicDrive® technology has continued to evolve since its inception.
Compared with the R-series HarmonicDrive® introduced to the market in 1982,
today’s CSF, CSG series is only three-fifths as tall, but capable of twice thepower transmission. The latest of the CSD series is only one-third as tall as
the R series, but still maintain a high level of torque and positioning accuracy.

Ultra-small strain wave gear speed reducer

2Principles of motion

High Torque Capacity and Accurate Positioning in a Compact, Lightweight Design
Planetary speed reducers are made possible based on our
expertise in precision machining technology.

HarmonicDrive® gear utilizes the elastic mechanics of metals.
Comprised of just three basic components, HarmonicDrive® offers small angle feeding and superior positioning accuracy
with no backlash due to its special teeth movement (operation principle) unlike the movement of common gears.
Because more than 30% of the teeth mesh simultaneously at the two opposing points, high torque transmission is possible.

Harmonic Drive Systems Inc. has used its extensive knowledge of HarmonicDrive® gearing to develop a highly precise andrigid epicyclic speed reducer called HarmonicPlanetary®.
Equipped with a unique backlash prevention mechanism, HarmonicPlanetary® delivers a high level of rotational accuracy.

Wave generator
The wave generator consists of a thin ball andbearing that fit into the outer circumference ofthe elliptical cam. The inner ring of the bearing
is fixed to the cam, while the outer ring deforms
elastically via the ball. Normally, this is installedon the input shaft.

Flex spline
This is the thin, cup-like, metallic, and elastic body.
The outer circumference of the opening has theteeth. The bottom of the flex spline (bottom of thecup shape) is referred to as the diaphragm, and isinstalled on the output shaft in the normal fashion.
Rear-stage planetary gear

Front-stage carrier + Rear-stage pinion

Circular spline
This is the rigid and ring-shape component.
The inner circumference has the teeth, and thenumber of teeth is higher than the flex spline by
two teeth. Normally, it is fixed to the casing.

The wave generator deforms the flex

When the circular spline is fixed, andthe wave generator (input) is rotatedclock wise, the flex spline deforms
elastically, and the position where theteeth of the flex spline meshes with thecircular spline teeth moves sequentially.

W hen the wave generator rotatesclockwise up to 180 degrees, the flex
spline moves counterclockwise only by
one tooth.

When the wave generator rotates one
turn (360 degrees), the number of flex
spline teeth is lower than the circularspline teeth by two teeth, and the flex
spline moves counterclockwise onlyby these two teeth. Normally, thismovement is used for an output.

Front stage: C onsists of a speed reducer

The rear-stage pinion coupled with the front-stage carrier
serves as an input to the rear-stage speed reducing part,and causes the orbital motion of the rear-stage planetary
gears as in the front-stage speed reducing part. The orbital
motion is transmitted to the rear-stage carrier (the inner ringof the cross roller bearing) and then outputted. The directionof rotation of the rear-stage carrier is the same as the input
direction, as in the front-stage speed reducing part.

The rotation from the input pinion causes theorbital motion of the front-stage planetary gears
that mesh with it. The orbital motion is transmitted
to the front-stage carrier via the planetary shaft.
The direction of rotation of the front-stage carrieris the same as the input direction.

Contributing to Social andIndustrial Innovation- Creating compact, lightweight, and high-precision products -- Creating a sustainable society with our "Motion Technology" -[Research & Development Policies]
The ideal driving the research and development by the HDS Group is toprovide more advanced motion control. To that end, in our R&D we carry out
both research and development on next-generation technologies and also
development and design tailored to customer needs, as we seek to cultivateand expand core technologies with an eye to the future, while improving
our ability to provide solutions for today. We also devote considerable R&D
efforts to production technology, in the form of engineering methods andequipment as manufacturing expertise necessary for production.

The I.K KAN research annex was completed on April 1, 2002
on the premises of the Hotaka Factory as the prototype of anext-generation manufacturing facility, for moving closer toideal motion control with the HarmonicDrive®.
Targeting a ten-fold improvement in accuracy, we are
pursuing sub-micron level processing precision by equipping
the facility with machine tools and measuring instruments
capable of high-precision processing and measurement.

The HDS Group’s mission is to contribute to technological innovation through business in order to help solve various social
issues and improve society. In fulfilling this mission, we base our management philosophy on four pillars: 1) Respect
for the individual, 2) a company with purpose, 3) coexistence and co-prosperity, and 4) contribution to society. This
management philosophy was created in the early days of HDS and has been passed down from generation to generation
as the corporate culture of the Group.
We believe that our management philosophy is the foundation of our sustainability efforts, and that our corporate
activities themselves contribute to the realization of a sustainable society.
Based on this management philosophy, we have established a Charter of Conduct, which sets forth the basic rules that
all employees of the HDS Group must observe in order to ensure compliance with laws and regulations, conduct businessethically, and preserve harmony with various stakeholders.

Sustainability

Achieving a Sustainable Society- Having an impact on society with technological innovation to better people's lives -As a first step, with the aim of realizing a sustainable society and enhancing our corporate value
over the medium term, we have formulated the following Basic Policy of Sustainability, which wasapproved by our Board of Directors on March 25, 2022.

Basic Policy of Sustainability
As a technology and skills-based organization in pursuit of Total Motion Control, the HDSIOne tenet of the HDS Group management philosophy is coexistence and coprosperity with the employees,
shareholders, customers, suppliers, and local communities who support our efforts. To this end the Group companies
strive through our corporate activities to contribute to the betterment of society and to improve the environment andquality of the local communities to which we belong.
The mission of the HDS Group, as a technology and skills team providing total motion control, is to give birth to futuretechnologies from new ideas. The people involved in research and development need to have a passion for making
things and the sensitivity for producing creative ideas.
In 2020, Harmonic Drive Systems Inc. celebrated its 50th anniversary. Over the years since our founding, throughvarious cultural activities we have refined the sensitivity demanded for making things.

Group aims to enhance corporate value and realize a sustainable society by contributing
to technological innovation for the betterment of society. We intend to achieve these goals
