Application of harmonic drive in machining industry -- end extension of truss manipulator

Working condition:

1. For injection molding machines and CNC machine tools, commonly used truss manipulators could realize more dimensional motion by adding one or two harmonic reducers, which can meet the needs of complex applications.

2. Output speed of truss manipulator's end joint is generally low, the speed ratio of reducers is between 80-160, and working conditions are not harsh.

Technical advantages:

1. Japanese HD brand reducers are replaced by ours, and the cost is reduced by more than 20%, and customized reducers are provided and delivery time is shortened by more than half.

2. Customer also uses Japanese brand Shrimpo planetary reducer. High-precision planetary reducer is expensive, and large ratio planetary reducers have two-stage planetary carriers with long axial dimensions, which affected design and compactness. Compared with planetary reducer, harmonic reducer has many advantages: higher accuracy; axial dimension is not affected by reduction ratio; specification III is hollow, and could go through cable, which is convenient for a customer design.

Future trends:

Order quantity of integrated customers has been increasing steadily in recent years. More and more end-users demand to add a multi-axis to end joint of truss manipulator to meet more complex application requirements.
