Hidrodinamik radyal kaymalı yataklarda yüzey pürüzlülüğünün sürtünme davranışları üzerindeki etkilerinin incelenmesi
Abstract
Hidrodinamik kaymalı yataklarda, sürtünme katsayısı, yağ film kalınlığı, basınç dağılımı, yağ debisi, vb gibi parametreler yatak tasarımı ve optimum enerji verimliliği açısından oldukça önemli tasarım kriterleridir. Bu çalışmada, hidrodinamik kaymalı yataklarda yüzey pürüzlülüğünün yatak performansı üzerindeki etkilerini incelemek amacıyla, yatak malzemesi aynı olan üç farklı yüzey pürüzlülüğüne sahip yatak zarfı kullanılarak farklı yüklerde ve sıcaklıklarda deneyler yapılmıştır. Deneylerin sonucunda, yüzey pürüzlülüğünün, özellikle sınır ve karışık sürtünme bölgesinde sıvı sürtünme bölgesinden daha fazla etkin olduğu belirlenmiştir. Artan yüzey pürüzlülüğü ile birlikte yağ filmi oluşum kabiliyeti azalırken, aşınma ve yataktaki güç kaybının arttığı tespit edilmiştir.

Investigation of the effects of surface roughness on friction behavior in hydrodynamic radial plain bearings
Abstract
In hydrodynamic plain bearings, parameters such as friction coefficient, oil film thickness, pressure distribution, oil flow, etc. are very important design criteria in terms of bearing design and optimum energy efficiency. In this study, in order to investigate the effects of surface roughness on bearing performance in hydrodynamic plain bearings, experiments were carried out at different loads and temperatures using two bearing envelopes with the same bearing material and with different surface roughness. As a result of the experiments, it was determined that the surface roughness was more effective especially in the boundary and mixed friction region than in the fluid friction region. It was determined that while the oil film formation ability decreased with increasing surface roughness, wear and power loss in the bearing increased.
