A Study of the Thermal Characteristics of the Leading Edge Groove and Conventional Tilting Pad Journal Bearings
Kingsbury, Inc., Philadelphia, PA 19154 In this paper dealing with the tilting pad journal bearing, experim'ental results are presented which show that, at higher shaft speeds, the leading-edge-groove (LEG) design has significantly lower operating temperatures to those of the conventional design of tilting pad journal bearing. Subsequent theoretical analysis has shown that this reduction in pad...
متن کاملProposal Performance Measurement of ATSP Coating and Bulk PEEK Faced Tilting - Pad Thrust Bearings
Background: Under severe operating conditions, such as lubricant contamination, elevated temperatures and high unit loads, the hydrodynamic (HD) lubrication condition in a HD bearing may degrade and be reduced to mixed and boundary lubrication conditions, which traditional pad bearing materials (Babbitt metal) are not able to sustain. For example, Electrical Submersible Pump (ESP) systems are r...
متن کاملThermohydrodynamic Characteristics of Journal Bearings Running under Turbulent Condition
A thermohydrodynamic (THD) analysis of turbulent flow in journal bearings is presented based on the computational fluid dynamic (CFD) techniques. The bearing has infinite length and operates under incompressible and steady conditions. In this analysis, the numerical solution of Navier-Stokes equations with the equations governing the kinetic energy of turbulence and the dissipation rate, couple...
متن کاملOn the Characteristics of Misaligned Journal Bearings
Journal bearing misalignment arise generally from the shaft deformation under load, deflection of the shaft, manufacturing and assembly errors, improper installation, and asymmetric loading. During operations, misalignment has a considerable effect on the static and dynamic performances. It could cause wear, vibration and even system failure. In this article, a literature review of misalignment...
متن کاملFault Diagnosis of Journal Bearings Based on Artificial Neural Networks and Measurements of Bearing Performance Characteristics
Two of the most common defects in rotating systems are abnormal wear of the bearing bushing and bearing misalignment. The present paper introduces a new fault diagnosis model that uses artificial neural networks (ANN) in order to identify the increase of wear depth and/or the increment of the misalignment angle. Reynolds equation is solved by FEM and provides data about bearing wear and misalig...
