Product Description
Compared with the LSS series of small harmonic drive, the LSN harmonic reducer has the same structure and performance as the LSS harmonic reducers. The only difference and advantage is its lighter weight; the weight of the LSN is 30% lighter. This is because we changed the material of the circular spline from steel to aluminum alloy.

What is a harmonic drive box?
+A harmonic drive box is a type of gear system that produces high reduction ratios in a compact size. It uses the mechanics of a flexible element deforming to transmit motion and achieve high precision and torque.
-
How does a harmonic gear box work?
+A harmonic gear box works by using a circular spline, flexspline, and a wave generator. The wave generator deforms the flexspline into an elliptical shape, which then engages with the teeth of the circular spline at two points, providing a high reduction ratio through the difference in tooth count between the engaged elements.
-
What are the main components of a strain wave drive?
+The main components are the circular spline (fixed outer ring), the flexspline (flexible inner ring with fewer teeth), and the wave generator (an elliptical disc that fits inside the flexspline).
-
What are the advantages of using harmonic/harmonic drive boxes?
+Strain wave/harmonic gearboxes offer high precision, zero backlashes, high torque capacity, compact size, and lightweight. They are also known for their excellent positional accuracy and repeatability.
-
What applications are harmonic-type drives used in?
+They are used in applications requiring high precision and reliability, such as robotics, aerospace, defense, medical equipment, and semiconductor manufacturing equipment.
-
How do you select a strain wave drive for a specific application?
+Selection depends on factors like torque requirements, desired reduction ratio, space constraints, load capacity, and environmental conditions. It's essential to consult with manufacturers or experts to choose the appropriate model.
-
What are the different types of Strain Wave Gearboxes?
+Circular Spline Gearboxes
Cup-Type Gearboxes
Flat Gearboxes
-
What is a Circular Spline?
+The Circular Spline in Strain Wave Gearboxes are characterized by their robust design.
