Harmonic Gear Reducer Transmission Error Analysis and Detection

Harmonic gear reducer is the key component of the electric servo system, its transmission error analysis and testing play a crucial role in the development, production, testing, assembly of gear reducer. According to the thin shell elastics deformation theory, the harmonic transmission principle is analyzed, and the harmonic transmission error sources. The calculation of transmission error is further discussed; the transmission error formula of harmonic gear reducer considering the case of gear backlash and stiffness is given. A harmonic gear reducer transmission error testing system is designed. This system can achieve the detection for the static and dynamic transmission error of harmonic gear reducer, the accuracy of measuring angular is batter than .
