PROBABILISTIC STUDIES FOR (SLIDE&ROLLING) BEARING SEIZURE DETERMINATION
Journal Title: Tribologia - Year 2015, Vol 262, Issue 4
Abstract
Selection, montage, and lubrication are the fundamental conditions, which have an influence on the correct and long-lasting work of bearing without seizure. The temperature of a correctly assembled and lubricated bearing cannot exceed 70°C, and lower temperatures are recommended during extended operation. The seizure can be caused by excessive load from poor seals or insufficient bearing clearance. After considerations about the seized and damaged bearings, we can estimate the probabilistic values of seizing. Technical literature describes this problem very widely and indicates the reasons for seizures. However, this literature rarely indicates the probabilities for seizures and the related damage, and no probabilities are related to the number of starts of the engine. In this paper, the probabilities of seizing are attributed to the causes of damage using experimental results. The paper also presents a probability analysis of the prognosis of the chance of seizing. Moreover, the highest number of starts of the machine that produced the most expensive losses due to seizing was determined by probability, and numerical examples are given.
