Analysis of Elastohydrodynamic Lubrication of Clamping Ball Screw of All-Electric Injection

Abstract:

This paper describes the development of all-electric injection molding machines, as well as the application of clamping ball screw, and elaborates the significance of researching lubrication of ball screw mechanism. The formula for calculating the minimum film thickness of ball screw is induced according to Hamrock-Dowson formula and contact parameters of ball screw mechanism. Using the parameters for a specific ball screw model calculates the minimum film thickness at the screw and ball contact. The lubrication state of ball screw is discussed. It provides a theoretical basis for the rational of ball screw lubrication and proper use.
