Sınır yağlama koşullarında çalışan kaymalı yataklar için test düzeneği tasarımı, yapımı ve iş makinelerinde aşınma analizi.

Excavators which used as earthmoving machinery are exposed to heavy loads and operate long hours repeatedly. The forces that are transmitted trough pin bearings are observed to cause failure due to wear. Therefore, durability of bearings is crucial for excavators. The aim of this study is to perform wear analysis of excavator bearings running in boundary lubrication regime. A hydraulically powered test rig, which simulates the operating conditions of excavator bearings is designed and constructed. Wear is obtained applying both force and relative motion between pin and bearing on the test rig. Several tests are performed in this test bench. Force and material type are varied as the factors influencing wear. Results are compared and the effects of the factors on wear are determined.M.S. - Master of Scienc
