LHD Shorten Thin Harmonic Gearbox

LHD Shorten Thin Harmonic Gearbox

LHD series's flex spline is a flanging ultra-short tube structure. The connection can be fixing the circular spline, flex spline as output; or fixing flex spline, circular spline as output. Without changing products' performance, LHD-I's axial length shortens 50%, LHD-III shortens 15%.


Application of this kind of strain wave reducer:

  • Industrial robots;

  • Humanoid robots;

  • Semiconductor manufacturing equipment;

  • FPD manufacturing equipment;

  • Space equipment.
