Study on the Lubrication of the Precision Ball Screw Mechanism
The lubrication effects of two types of universal lubrication methods for ball screw mechanism are firstly discussed.For lubrication in oil,the variation situation of the thinnest lubricating oil film thickness vary with the ball screw rotation is figured out according to the Hamrock-Dowson expressi...

| description | The lubrication effects of two types of universal lubrication methods for ball screw mechanism are firstly discussed.For lubrication in oil,the variation situation of the thinnest lubricating oil film thickness vary with the ball screw rotation is figured out according to the Hamrock-Dowson expression and the fact that the ball screw always runs on conditions of boundary lubrication is identified by the calculation of the film thickness ratio.For lubrication in grease,the fluctuation curve of the ball speed responds to the ball screw rotation is figured out through the analysis of their mutual motion and geometric relationship.The curve demonstrates that using the grease to lubricate the ball screw mechanism with high rotation rate will cause higher temperature rise.To overcome the above two shortages,a dynamic grease coating lubrication method is proposed.Lastly,a friction torque stabilization test and a temperature rise test are conducted to prove the superiority of the proposed method. |
