GIGAGER supplies a full size range of high cost performance reducers that matches the Japanese and American harmonic. They are the perfect alternative harmonic speed reducers for your limited budget.

1. Introduction

Invented by the American inventor C.W.Musser in 1955. It is a new type of transmission that utilizes the elastic deformation of the flexible working member into the motion or power transmission. It breaks through the mechanical transmission using rigid members. The mechanism’s model uses a flexible member to achieve mechanical transmission, resulting in a range of special features that are difficult to achieve with other transmissions. The deformation process of the intermediate flexible member is basically a symmetrical harmonic. In addition to the former Soviet Union referred to this type of transmission as wave drive or flexible wheel drive, the United States, Britain, Germany, Japan and other countries are called Harmonic Transmission.

3. System Configuration

Composed by three core parts, Circular Spline, Flexspline and Wave Generator.

Component
Wave Generator	The Wave Generator is a thin, raced-ball bearing fitted onto an elliptical hub. This serves as a high-efficiency torque converter and is generally mounted onto the input or motor shaft.
Flexspline	It is a non-rigid, thin cylindrical cup with external teeth on the open end of the cup. It fits over the Wave Generator and takes on its elliptical shape. The Flexspline is generally used as the output of the gear.
Circular Spline	It has two more teeth than the Flexspline and is generally mounted onto a housing.
