Compact Harmonic Speed Reducer Strain Wave Gear Model 25 Customized

30% Lighter Harmonic Reducer Gears Strain Wave Reducer

LSN series harmonic reducer is ideal for applications where weight is a critical factor, but high torque and zero backlash are required. LSN - 25 - XX - U - II is a 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. It is available in 5 sizes with ratios 50:1 to 120:1.

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: 98Nm to 167Nm Reduction ratios 50:1 to 120:1 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
