One of the directions of modernization of the power supply system for hydrostatic bearings is automatic adjustment of
stiffness and their load-bearing capacity. Therefore, the paper solves the problem of rapid, targeted force action on load
changes in hydrostatic resistances of technological equipment to compensate for loads occurring during the manufacturing
process of the part.
To solve these tasks, it is recommended to use high-and ultra-high-pressure jet technologies, which are widely used in
various industries. To do this, it is necessary to choose the optimal operating modes from the energy and consumption points
of view, and select the working fluid parameters individually. Well-known studies show that the performance of jet technologies
increases rapidly with increasing pressure of working fluids, so it is advisable to use high-and ultra-high-pressure liquid jets.
However, obtaining stationary jets with such parameters is associated with great technical difficulties.
Analysis of research and publications in the field of modernization of hydrostatic bearings based on jet technologies has
shown that the issues of controlling shaft movements under loads during rotation of the Rotary unit are currently given little
attention in the scientific literature.
The purpose of this work is to develop theoretical approaches and practical recommendations for the use of jet
technologies for force action on the shaft of a hydrostatic bearing to compensate for the radial displacement of the shaft under
load, reduce shock loads and wear of the support surfaces of the conjugated parts of the hydrostatic unit.
The performed studies made it possible to obtain pressure plots in the upgraded hydrostatic bearing based on jet liquid
supply technologies to the hydraulic unit. Computer modeling of the formation of pressure fields in a conventional and
upgraded hydrostatic bearing was also performed. |
