Tapered roller bearings are often used to support pinions in gear units of electric trains. On the other hand, recently, the application of cylindrical roller bearings with ribs has also been proposed, in which the internal clearance changes little depending on the operating conditions. This study aims to elucidate the effect of differences in just these two types of pinion bearings on the performance of gear units and thereby verify the applicability of cylindrical roller bearings with ribs to railway gear units. Tapered roller bearings and cylindrical roller bearings with ribs of the same dimensions were subjected to rotational tests in the same gear unit. The results showed that the effects of the atmospheric temperature on the maximum temperature, the maximum rate of temperature rise, and the torque of the bearings were not significantly different between the tapered roller bearings and the cylindrical roller bearings with ribs. As the atmospheric temperature decreases, the maximum temperature decreases, and the maximum rate of temperature rise and the torque increase. On the other hand, the endplay values had a significant effect on these values in the tapered roller bearings, while they had little effect on the cylindrical roller bearings with ribs.

Concern over commercial mineral-based grease’s impact on the environment and its unrenewable resources requires a more sustainable alternative in lubrication. In this research, a palm olein-based grease was developed, and the effect of particle size of molybdenum disulphide (MoS2) additives on the grease performance was experimentally evaluated. Molybdenum disulphide additive of 0.5 wt.% concentration that varied in size was added to the palm olein grease. The friction reduction and wear characteristics of the developed lubricants were evaluated using a four-ball tribometer. The wear surfaces were analyzed by scanning electron microscope, energy dispersive spectroscopy and infinite focus microscope. It was discovered that MoS2 improved the grease performance, and a nano size of 90 nm exhibited the best performance in reducing friction coefficient, wear parameters and surface roughness. This study suggests the potential of palm olein-based grease with MoS2 additive to be used as a lubricant.

The application of data mining technology has intensively advanced tribology research. While recent lubrication studies have highlighted the importance of data mining, researchers have not fully bridged the gap between massive lubrication data and intrinsic lubrication mechanisms. Thus, by revisiting lubrication modelling from the data-driven and physics-informed perspectives, we aim to construct a hybrid approach for hydrodynamic lubrication classification and prediction, where data-driven methods are combined with physics-informed approaches to achieve a fast and accurate prediction of the hydrodynamic lubrication scenario. Our approach will spur the application of data mining methods in lubrication studies.

Lead-bismuth bearing performance and dynamic properties are crucial for ensuring the steady operation of lead-bismuth liquid metal pumps since they are one of the primary supporting elements in the lead-bismuth cold fast reactor system. To study and analyze the lubrication performance of lead-bismuth bearings as well as the influence of the viscous-temperature property of lead-bismuth medium on the bearing load performance, a hydrodynamic model based on CFD (Computational Fluid Dynamics) is established. The performance of lubrication comprises addressing the static and dynamic properties of lead-bismuth bearings. The pressure and temperature flow fields of the Lead-bismuth bearing under various working conditions were determined by solving the N-S equation and energy equation. The numerical findings demonstrate a clear strip-like distribution in the temperature and pressure flow fields of the lead-bismuth bearing. The pressure flow distribution in the working and feedback grooves is symmetrical, the temperature flow distribution is isotropic, and the temperature increase is mostly proportional to the rotation speed. As the rotation speed becomes larger, the force in the y-direction, power loss, and leakage flow rate all increase. Bearings with small radius clearance and greater rotation speeds have superior stability than those with big radius clearance and lower speeds. The findings of this paper serve as a point of reference for the study of the viscosity-temperature effect and lubrication theory of lead-bismuth bearings and supply the foundation for subsequent rotor dynamics calculations.

A novel electrical contact wear simulation method was proposed to characterize the electrical contact wear of fittings in ultra-high-voltage transmission lines by combining line fittings with the Archard wear model and oxidation loss theory. In this method, a three-dimensional (3D) rough body was generated by using the Weierstrass–Mandelbrot fractal function to simulate the contact surface. An electrical contact wear subroutine was developed, and the wear state was updated using arbitrary Lagrangian–Eulerian adaptive grid technology. Finally, finite element software was used to perform thermal stress wear coupled analysis. The results show that the wear volume, wear depth and friction temperature obtained by the rough electric contact model were 2.71 times, 4.21 times and 2.18 times of the common ideal plane model, respectively. In the rough model, the wear depth of the nodes initially accelerated, subsequently slowed down, and again accelerated with time. The friction high temperature region was distributed in a point pattern, and the temperature difference between the contact region and the non-contact region became obvious.

The present article deals with the effects of deformable bearing shells on the performance of lobed slot-entry hybrid journal bearing systems. The influence of the deformation coefficient [Formula: see text] has been studied using the thin liner elasticity model, which measures the flexibility of the bearing liner. Recently, smart fluid, that is, electrorheological (ER) fluid has been used in various tribological systems to obtain better performance. Therefore, the influence of ER lubricant on the bearing performance characteristics has also been studied in this work. Bingham model constitutive relation has been used to analyze the non-Newtonian behavior of ER fluid. The performance of fluid film bearings is greatly influenced by the noncircularity of the bearings. Therefore, the behavior of deformable bearing shells in a slot-entry journal bearing for lobed conditions has also been studied in the present study. The results reveal that considering deformation in the bearing shell reduces the value of frictional torque, whereas the value of stiffness coefficients and stability threshold speed increases. However, ER lubricant enhances the value of film thickness, stiffness/damping coefficients, and stability threshold speed margin.

Composite materials have an ever-increasing demand for their application in numerous applications such as aerospace, automobile, petroleum, etc. These materials vary according to their chemical composition, properties, manufacturing techniques, etc. Natural fiber-reinforced composites are the composites where natural fibers such as plant, animal, and mineral fibers are used as reinforcement material. Reinforcement of these fibers yields composite material with extensive properties such as high strength, durability, reliability, etc. These properties lead them to commercial applications in several areas. Therefore, this paper describes various characteristics of the matrix, reinforcement, and resin used for natural fiber composite materials. Also, multiple parameters that affect the growth of these composites are investigated. The tribological behavior of natural fiber composites is focused mainly on friction, wear, and lubrication. Furthermore, the material's mechanical performance and metallurgical behavior are also given significant importance. These materials’ application in various fields is explored separately, and multiple conclusions are drawn.

Results of an experimental study on the levitation of a light object created by the squeeze-film mechanism under both vacuum and atmospheric conditions are presented and discussed. Two working substances were used, that is vacuum pump oil and ionic liquid. It was determined that vacuum pump oil produced a much higher levitation altitude of the floating light object compared to the ionic liquid. Also, it was established that levitation can be achieved under both vacuum and atmospheric conditions. The levitation height of the light object was slightly higher under vacuum conditions.

This paper presents a critical review on the measuring methods and parameters affecting nano-tribology in the context of nano-scale wear. Nano-scale wear phenomena play a crucial role in various industries, including micro/nano-systems, electronics, and biotechnology. The review begins by discussing the significance of nano-scale wear and its impact on device performance, lifespan, durability, energy efficiency, cost savings, and environmental sustainability. It then delves into the measuring methods employed to assess nano-scale wear, including scanning probe microscopy (SPM) techniques such as atomic force microscopy (AFM) and friction force microscopy (FFM). The capabilities of AFM and FFM in studying the roughness of surface, adhesion, friction, scratch, abrasion, and nano-scale material transfer are highlighted. Additionally, the review explores the parameters affecting nano-wear, such as lubrication strategies, stress levels, sliding velocity, and atomic-scale reactions. The article concludes by emphasizing the importance of advanced microscopy techniques in understanding tribological mechanisms at different scales, bridging the gap between macro and nano-tribology studies.
