摘要
This article describes a theoretical analysis of a hydrostatic journal bearing for a crankshaft pin turner by considering the waviness error of the journal and bearing. The authors found adequate design parameters to operate the crankshaft pin turner bearing. The flow rate, radial clearance, and eccentricity were selected as the basic design parameters. The load-carrying capacity of the bearing as a function of the design parameters was studied in the case of a true circular journal and bearing. The influence of the waviness error on the load-carrying capacity was then investigated; cosine functions were selected for the waviness functions. As a result, the load-carrying capacity varied according to the amplitude and phase angle of the waviness functions. Thus, it was found that the influence of the waviness error is a significant factor in analyzing lubrication characteristics. %26lt;br%26gt;Run-out accuracy analysis method according to the waviness phase angles of the journal and bearing was suggested. It was found that the phase angles between the bearing load wave and load-carrying capacity wave are important factors that affect the running accuracy in addition to the amplitude of waviness error.
