Návrh hydrostatického vedení smykadla svislého soustruhu a návrh testovacího zařízení s uvedením základních dat řešeného případu včetně rovnic, popisujících vztahy mezi mechanickými a hydraulickými veličinami.

This article will focus on a computation of a hydrostatic guideway of a vertical lathe ram. Basic data of the solved problem are introduced as well as basic considerations concerning governing equations describing mutual relations between hydraulic and mechanic quantities. The equations of Reynolds, Laplace and Hagen-Poiseuille are mentioned. Computations carried out by means of Excel and Maple are discussed and some schemas and computation results are shown. The main goal of the computation and the design of the hydrostatic guideway of an vertical lathe ram was to prepare the basic documentation of a prototype for the ram maximum load of Fz=50 000 N, Fx=Fy=22 500 N whereas the maximum ram shift is 550 mm. The results of the computation of the hydrostatic guideway of the vertical lathe ram are introduced and the design of the hydraulic circuit is shown.
