Harmonic Drive Systems Inc. is making every effort to develop supportive technologies for the
21st century, thereby contributing to the advancement of global technology.

Features

High rotational and positioning accuracy, compact and light weight, high reduction ratio, high torque capacity,
non-backlash, high efficiency, silent operation

Structure

Driven by a unique operating principle applying metal elastodynamics and comprising only three basic parts (a wave generator, flexspline and a circular
spline), our HarmonicDrive wave motion gearing (registered trademark) excel with superb characteristics that are not found in other wave motion gearing
products.

 

HarmonicDrive® Structure of HarmonicDrive® Unit (Component Type)

Flexspline

The Flexspline is a non-rigid, thin cylindrical cup with external teeth, with a slightly smaller pitch diameter than the Circular Spline. The bottom of the Flexspline is called the diaphragm, and is usually mounted onto the output shaft.

Wave Generator

The Wave Generator is a thin raced ball bearing fitted onto an elliptical hub serving as a high
efficiency torque converter, and is generally mounted onto the input shaft.

Circular Spline

The Circular Spline is a rigid ring with internal teeth of the same size as the Flexspline, but the
Circular Spline has two more teeth than the Flexspline and is generally mounted onto the housing.

Operating Principle 

There are three main components. The Flexspline is bent into an elliptical shape by the Wave Generator; and the teeth of the
long axis of the ellipse engage with the Circular Spline, whereas the teeth of the short axis are completely separated.
As the Circular Spline is fixed in place and Wave Generator (input) rotates in a clockwise direction, the Flexspline deforms elastically and the position where the gears mesh with the Circular Spline moves in turn. For each rotation of the Wave Generator, the Flexspline rotates backwards by only two teeth from its original position, or in other words in the reverse direction relative to the Wave Generator. This motion is generally retrieved as the output.

Tooth behavior and engagement

Unlike the motion of ordinary gears, the unique tooth behavior (operating principle) of the
HarmonicDrive® makes non-backlash motion possible, as well as infinitesimal angular feeding
(one-pulse feeding) and high positioning accuracy. More than 30% of all teeth simultaneously
engage in two locations in 180° symmetry, allowing for high torque capability.

CSG-2UH Series

Unit/High-torque & Light weight Type

To realize a high load capacity and high reliability, the torque capacity has been increased by 30% compared to the CSF
series.
A lightweight type has been added to the CSG series lineup. (Compared with the previous type, weight has been reduced by30%)

  • High torque capacity
  • High stiffness
  • Compact and simple design
  • Non-backlash
  • High positioning and rotational accuracies
  • Coaxial input and output
  • Light Weight

CSG-2UK Series

Unit/Sealed Structure, High-torque Type

This product provides ease of designing and handling by incorporating a sealed structure. Consider the use of this series for mechanical sections such as the work conveyers and magazine drivers of machine tools, or in general industrial machines.

  • High torque capacity
  • High stiffness
  • Compact and simple design
  • Non-backlash
  • High positioning and rotational accuracies
  • Sealed structure

CSD-2UH Series

Unit/Super Flat, High Load Capacity Type

In response to market needs, we have considerably downsized the products in our HarmonicDrive® CSD Series. The CSD-2UH is more compact than the CSF series of the equivalent torque capacity. The CSD-2UF has a hollow structure with an output side bearing that has around twice the load capacity as large as the same model no. product from the SHD series.

  • Super thin
  • Hollow structure
  • High positioning precision
  • High load capacity

CSD-2UF Series

Unit/Super Flat, High Load Capacity Type

In response to market needs, we have considerably downsized the products in our HarmonicDrive® CSD Series. The CSD-2UH is more compact than the CSF series of the equivalent torque capacity. The CSD-2UF has a hollow structure with an output side bearing that has around twice the load capacity as large as the same model no. product from the SHD series.

  • Super thin
  • Hollow structure
  • High positioning precision
  • High load capacity
