Large Hollow LHT - III Series Harmonic Gears

Product description

Strain wave gearing (also known as harmonic gearing) is a type of mechanical gear system that uses a flexible spline with external teeth, which is deformed by a rotating elliptical plug to engage with the internal gear teeth of an outer spline.

Strain wave gearing utilizes a unique operating principle which is based upon the elastic mechanics of metals. The greatest benefits are the zero-backlash characteristics and the weight and space savings compared to other gears because our gear mechanism consists of only three basic parts. They are the: Wave Generator, Flexspline and Circular Spline.

Strain wave reducer consist of three main components Wave Generator: An elliptical cam that fits inside a flexible cylindrical spline (Flexspline). The wave generator deforms the flexspline into an elliptical shape. Flexspline: A flexible cylindrical component with external teeth that match the internal teeth of the circular spline. Circular Spline: A rigid ring with internal teeth that engage with the flexspline.
