High Accuracy Gears LSN - II Series Model 20 Lightweight Strain Wave Reducer

LSN series are high torque housed component gear set combined with a precision cross roller output bearing & flange. It is a very compact, robust and easy to use gearhead solution. The LSN II series is available in 5 sizes with ratios 50:1 to 160:1. If your application does not require high torque, LSN series gearhead is a great alternative gearhead. There is also a lightweight version.

LSN series is the lightweight product line, designed to reduce the weight of the mechanical equipment itself and facilitate the lightweight construction of industrial robots. It enables higher speeds and increased payload capacity for industrial robots.

How it Works

The Flexspline is slightly smaller in diameter and has two fewer teeth than the Circular Spline. The elliptical shape of the Wave Generator causes the teeth of the Flexspline to engage the Circular Spline at two opposite regions across the major axis of the ellipse. For every 180 degree clockwise rotation of the Wave Generator the Flexspline teeth are advanced counterclockwise by one tooth in relation to the Circular Spline. Each complete clockwise rotation of the Wave Generator results in the Flexspline moving counter-clockwise by two teeth from its original position relative to the Circular Spline.

Key Features Zero Backlash Peak Torque at Start and Stop: 56Nm to 92Nm Reduction ratios 50:1 to 160:1 30% average lower weight than Standard Series High torsional stiffness High efficiency Compact and simple design Robust cross roller output bearing Output flange for direct mounting of load
