Harmonic Gearing –GCSG series

  Harmonic Gearing is also called as Strain wave gearing is a mechanical type of gearing system that has flexible spine with external teeth which is deformed by a rotating elliptical plug to engage with the internal gear teeth of an outer spine Some advantages of Harmonic Gearing ·         No backlash ·         Compactness and light weight ·         High gear ratios ·         Reconfigurable ratios within a standard housing ·         Good resolution ·         Excellent repeatability ·         High torque capability ·         Coaxial input and output shafts Strain wave gearing is commonly used in robotics and aerospace. It can be used in gear reduction but also in increase rotational speed. The strain wave or harmonic Gearing uses the elasticity of metal. The mechanism has three basic component 1)     Wave generator 2)       Flex spline 3)     Circular spline More complex version has fourth component normally used to shorten the overall length. But it also
