Influence of the Number of Planet Gears on Planetary Meshing Noise

抄録

Planetary gear trains (PGTs) are very popular for power transmission and extensively used in various industrial fields such as automobiles. Despite their advantages, negative impacts from noise and vibration on the customer perception of quality are an ongoing issue. In this study, an original full wireless test stand in an anechoic chamber was used to directly measure the sound levels of different numbers of planet gears to consider the noise problem of PGTs. Because the torque capacity changes with the number of planet gears, two conditions were considered: a constant output torque and a constant meshing stress.
