Abstract

Aiming at the problem of high vibration and noise caused by unstable meshing of driving chain in the actual working condition of power turret, based on the theory of non-linear dynamics and virtual prototyping technology, taking AK33125 power tool holder as the research object, a 6-level and 7-gear driving dynamic model of tool driving module is established. The dynamics of tool driving transmission chain was studied, and the dynamic response of relevant parameters to transmission chain was analyzed.The results showed that proper damping between gear pairs could improve the stability of transmission chain; smaller load torque could reduce the amplitude and frequency of speed fluctuation of transmission chain; the frequency and amplitude of speed fluctuation of transmission chain would increase with the increase of input speed of motor gear.In actual working conditions, the vibration noise of tool holder can be reduced by changing lubrication modes properly to increase meshing damping between transmission chain gears, adding cutting fluid to reduce cutting load properly and reducing motor speed properly without affecting cutting efficiency.
