Abstract

A transverse-rotational-axial coupled dynamic model for a cylindrical gear pair was built considering excitations of time-varying mesh stiffness, gear error and meshing impact. And the effects of different helix deviations on the vibration of a spur and helical gear pair were investigated. The results showed that the helix deviation has little effects on the vibration of spur gears but has remarkable influences on the vibration of helical gears. The concave helix always brings the largest vibration, and the negative helix angle errors produce smaller dynamic loads than the concave helix. Under most load conditions, the positive helix angle errors bring a smaller vibration than the ideal helix does and the convex helix has the smallest vibration of all. Therefore, the helix deviation can be neglected when studying the dynamic responses of spur gears but should be taken into account when studying the dynamic responses of helical gears.
