To the vibration problem of the ball screw mechanism of textile machine

the dynamic vibration model of ball screw transmission mechanism is established

the preload

the mass of work table

the torsional stiffness

the equivalent axial stiffness and the axial stiffness of ball nut and the mass of ball screw to influence on a ball screw drive system vibration characteristics are studied

in the form of vibration acceleration for the vibration characterization.The research results show that with the preload

the torsional stiffness and the equivalent axial stiffness

the axial stiffness of ball nut increase and the mass of work table

the mass of ball screw decrease

the vibration acceleration peak frequency of ball screw is increased.With the preload

the axial stiffness of ball nut increase and the mass of work table and ball screw decrease

the vibration acceleration peak value increase.With the increase of torsional stiffness

the vibration acceleration peak value shows the tendency of first decrease then increase at last decrease.With the increase of equivalent axial stiffness

the vibration acceleration peak value shows the tendency of first increase then decrease;with the increase of preload

the ball screw transmission power increase.
