Abstract

(TR)

Hidrostatik yataklar, yüksek basınçlı ve nispeten ince yağ filmleri sayesinde, yüksek sönümleme, rijitlik ve yük kapasitesi gibi avantajlarının yanında son derece düşük hareket hataları potansiyeline sahiptir. Genellikle boyutsal ve geometrik toleranslar son derece yüksek hassas olduğundan birçok makine üreticisi de kendi hidrostatik yatak sistemlerini tasarlamayı ve üretmeyi tercih etmektedirler. Bu makalenin amacı, bir eksenel hidrostatik yatağın performansını değerlendirebilecek ve yatak tasarımına yardımcı olabilecek bir analitik modeli gerçekleştirmektir. Böylece hidrostatik yatak geometrilerinin yük kapasitesi, gerekli debi, rijitlik, ve güç tüketimi için hesaplamaları yapılabilecektir. Aynı zamanda performans üzerinde etkili olan tasarım parametrelerinin cevap yüzeyi yöntemi (CYM) kullanılarak bir değerlendirilmesi de yapılarak optimal tasarımlar elde edilecektir.

Hydrostatic bearings have the advantages of high damping, stiffness and load capacity, as well as the potential for extremely low movement errors due to their high pressure and relatively thin oil films. Since dimensional and geometrical tolerances are usually extremely precise, many machine builders prefer to design and manufacture their own hydrostatic bearing systems. The aim of this paper is to realize an analytical model that can evaluate the performance of an axial hydrostatic bearing and assist in bearing design. This will enable the calculation of hydrostatic bearing geometries for load capacity, required flow rate, stiffness, and power consumption. At the same time, an evaluation of the design parameters affecting the performance using the response surface method (RSM) will be performed to obtain optimal designs.
