Optimization Design of Precision Small Module Non-uniform Planetary Gear Transmission
This paper takes a precision small-modulus planetary gearbox as an example,analyzes the calcula-tion method and steps of the installation angle when the planet gears are non-symmetrically distributed.It com-pares the effects of different installation angles on radial forces and proposes that an installation angle as close as possible to an evenly distributed one can help minimize radial forces and improve system life.It also optimizes the shape of the non-uniform transmission to reduce the fluctuation of transmission error and improve the contact patch loading of the tooth surface,further improving the gear mesh quality and increasing the service life.
