THE INFLUENCE OF BEARING INTERSPACE GEOMETRY ON HELICAL GROOVED JOURNAL BEARING LOAD CARRYING CAPACITY
Journal Title: Tribologia - Year 2010, Vol 233, Issue 5
Abstract
Investigations concerning the influence of a helical groove on the load carrying capacity of hydrodynamic plain bearing are presented in the paper. Two indicators were developed as a result of investigations. The first indicator is a quotient of groove volume and bearing interspace volume. It has been stated that, if the value of this indicator does not exceed 0.5% the load carrying capacity of the grooved bearing is above 90% that of classical bearing. The second indicator is a quotient of the groove’s cross-section area and bearing interspace cross-section area in the place of minimum bearing interspace thickness. It has been stated, that if the value of this indicator does nott exceed 2% load carrying capacity, the decrease in load capacity of the grooved bearing is less than 10% in relation to a bearing with smooth journal. The above mentioned dependencies are initial and should be studied in additional investigations.<br/><br/>
