AbstractPurpose -The journal bearings subjected to heavy load and slow speed operate in mixed lubrication regime causing contact between the interacting surfaces and resulting in wear. Complexity of wear behavior and lack of unifying theory/model make wear-control very challenging. Design/methodology/approach -In the present research work, theoretical and experimental investigations have been conducted to explore the effect of grooving arrangements on the wear behavior of journal bearing operating in mixed lubrication regime. The theoretical model of Hirani (2005) that uses mass conserving cavitation algorithm has been used to determine the bearing eccentricity for different groove arrangements (with varying groove location and extent) for identifying a groove arrangement that minimizes the wear. The wear tests on the grooved bearings were conducted after suitable running-in of the new bearings on a fully automated journal bearing test set-up. A load and speed combination required to operate the bearing in mixed lubrication was used. The performance of different arrangement of bearing was evaluated by measuring their weight loss after the test. Findings -Wear was significantly reduced with the use of proper groove arrangement for a bearing operating in mixed lubrication regime. Originality/value -The improvement in bearing performance by providing grooves has been the subject matter of several studies in the past, but these studies were confined to the hydrodynamic operative regime of the bearing. In the present work, seven different combinations of axial and radial groove arrangement were tried, which has not been reported in any other work.Lijesh K.P. can be contacted at: lijesh_mech@yahoo.co.in For instructions on how to order reprints of this article, please visit our website: www.emeraldgrouppublishing.com/licensing/reprints.htm Or con...

“…Spherical bearing is an important part of the motor to achieve rotation and support. Even in the process of using precision machinery manufacturing, wear, depression, peeling 3 and other phenomena may have an irreversible impact on the dynamic characteristics of the spherical bearing. Therefore, the most important thing is to improve the bearing capacity of spherical bearing and reduce the vibration caused by the change of contact stiffness of rotor and stator with time.…”

Based on the liquid suspension three-degree-of-freedom motor, the three-degree-of-freedom dynamic model of spherical bearing is established. The spatial distribution of the radial electromagnetic force is calculated. The results show that the second harmonic has the greatest influence on the motor vibration. At the same time, considering the roughness of rotor surface, the pressure distribution and film thickness distribution of oil film are calculated by the finite difference method. Through the finite element method, the force of the stator spherical shell and the rotor is analyzed when the rotor slips. Moreover, the oil film modal is calculated and it is found that the forward precession is stronger when the oil film whirls. Finally, the experimental platform is built. The vibration amplitude of the spherical bearing under the condition of normal operation and oil whirl was measured. By comparing the relationship between vibration amplitude and vibration frequency, it is found that oil whirl causes negative vibration growth of spherical bearing, which leads to dry friction between rotor and stator. It provides a good theoretical basis for the practical application and further optimization design of spherical bearing.

“…Phosphor bronzes exhibit superb spring-like qualities, a high fatigue resistance, excellent formability and solderability, and a high corrosion resistance. Further, they allow for twice the maximum pressure than that for tin bronze bearings [ 9 , 10 , 11 ]. Further, their high strength and wear resistance make them suitable for applications involving high degrees of wear and abrasion.…”

Restoration of Worn Movable Bridge Props with Use of Bronze Claddings

This article examined the possibility of using CuSn6P claddings in sliding bearing renovation of movable pontoon bridge props. The bronze layer was welded on cylinders of the high-strength steel S355J0WP EN 10155-93, in an inert atmosphere using an automated welding method (gas tungsten arc welding). Pulsed arc welding was used to minimize the effects of heat on the cladding area, while also accounting for the differences in the physical properties of the joined metals. The sliding bearing was created in two layers. The quality of the cladding layer was evaluated by nondestructive and/or destructive tests. The quality of the surface was assessed by visual inspection (visual testing) in accordance with the EN ISO 17637 standard. The quality of the claddings was evaluated by metallographic analysis, performed using light microscopy. The microhardness values of a few weld areas were determined by Vickers tests, performed according to the EN ISO 9015–2 standard. The analyses confirmed that the welding parameters and filler material used resulted in high-quality weld joints with no internal (subsurface) or metallurgical defects.
