Modeling and Analysis for the Transmission Characteristics of a Proposed Dual-Drive Hydrostatic Lead Screw SystemSource: Journal of Tribology:;2022:;volume( 144 ):;issue: 007::page 71202-1DOI: 10.1115/1.4052422Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a novel dual-drive hydrostatic lead screw system (DDHLS). The design enables a lower feed speed and a better transmission performance than the conventional hydrostatic lead screw (HLS). Considering the nut-misalignment, the lubricating mathematical model of the DDHLS is established based on the perturbation method and solved by the finite difference method. The influences of the nut-radial-displacement, the nut-tilt, and the dual-drivable design on the transmission performance of the DDHLS are researched. The results show the nut-misalignment can regularly reduce or increase the axial load capacity (ALC), the axial stiffness coefficient (ASC), and the axial damping coefficient (ADC). Significantly, the dual-drivable design can improve the axial load capacity and the axial stiffness coefficient while hardly affects the axial damping coefficient.
