Abstract

Photovoltaic module installation equipment is a new type of special equipment. In order to reduce the vibration of the system and ensure the stable and accurate installation of the photovoltaic module, aiming at the fine-tuning condition of the dual power input of the planetary gear train in the power transmission system, this paper adopts the lumped mass method, considering the time-varying meshing stiffness, tooth side clearance and other nonlinear factors, a translation-torsion nonlinear dynamic model is established. On this basis, the influence of manufacturing and installation errors of each gear tooth on the vibration and load sharing characteristics of the gear train is studied. The research shows that when there are manufacturing and installation errors, the floating sun gear can automatically center to adapt to the influence of errors, and the sun gear deviates the farthest from the theoretical origin under the planet carrier error. Planetary gear error has the most significant impact on the system response, compared with other parts of the vibration displacement generated by the error magnitude difference. When all planetary gears produce the same error, the load sharing characteristics of the system will be better than that of a single planetary gear error.
