Abstract

See full text

A method for determining timing of oil filling for a ball screw can determine whether the oil film in a specific time period is sufficient, falling or insufficient, and then know the optimum timing of oil filling, by comparing the sum of the slope values within respective time periods with a predetermined value. The method is further capable of determining the timing of oil filling even when the rotation speed of the ball screw changes. The method includes a step of signal acquisition, a step of converting signal, a step of defining and saving eigenvalues, a step of calculating eigenvalues, and a step of determining oil filling.
