The embedding situation between various nanoparticles and rough surfaces affects the lubrication characteristics of rolling bearings. If not properly handled, this can easily lead to wear damage of rolling bearings. Therefore, the friction and wear mechanism of nano-lubricated high-speed rolling bearings under various nanoparticle embedded states is studied in this manuscript. Mixed oils containing different sized SiO2 nanoparticles and dispersants are prepared, and then the tribology test of nano-lubricated high-speed rolling bearings considering the interaction between various nanoparticles

Abstract:

This article discusses the evolution of bearings and its functional use in making a wheel work. The beginning of the anti-friction bearing industry started in the early 1880s when Friedrich Fischer in Germany developed a way to manufacture precision spherical balls economically in high volumes and gave birth to Fischer AG. As per the early technology for producing bearings, the factory’s grinders were driven by belt and pulley arrangements connected to a single power source. Developments in the electronic field gave the bearing industry the tools to verify these theories, to understand the fun

Abstract Bearings, as one of the most central components of rotating equipment, are widely used both in servo steering gear, aerospace and other fields. However, for extremely cryogenic conditions, the life of bearings is low, so it is necessary to carry out the tribological design of bearings to improve its cryogenic performance. In this paper, four kinds of optimized and improved plain bearings are designed. The tribological tests of these four bearings under extreme cryogenic working conditions were carried out using the developed bearing simulation test rig. The results show that under the

Friction wear is inevitable in roller bearings at high speeds, under heavy loads and vibration, and in other operating conditions. The use of grease can significantly reduce frictional wear. Sulfur–phosphorus additives have excellent anti-wear properties, oxidation resistance, and stability under high load and high-speed conditions. Their application in roller bearings enhances the performance of the grease, thus ensuring the normal operation of roller bearings.

The research purpose is to realize a multi-stage model developed by the authors to show fatigue failures accumulation and failures of anti-friction materials and layers in slider bearings.  The model describes: a scattered accumulation of micro-cracks, formation and development of a micro-crack system up to a limiting state of an object. There are solved some problems. The problem of model parameter identification on the basis of the analysis of babbit sample tests is solved with the use of the simplest optimization method – a method of a deformable polyhedron.  At that there are u

Abstract:

An essential condition to ensure an engine life having 300,000 – 1 000,000 km according to race consists in assurance of a minimum wear rate of crankshaft bearings. For such units as connectingrod bearings a maximum allowable value of bearing brass wear makes 100 mkm which corresponds to an integral linear wear intensity of 10-14 …10-13 that is possible only at a hydrodynamic mode of friction actually at all modes of engines operations. Ensuring liquid friction in all range of contact pressures is achieved both through design methods, and technological ones. To the latter belongs first of all

Abstract:

With a growing global railway market which needs to reduce its energy consumption and emissions, railway wheel-end bearing units are being optimized to further reduce power losses with no compromise on reliability. One of the different solutions being evaluated is the selection of the optimum surface engineering. Inner and outer rings of railway bearing units are currently coated with a zinc-calcium phosphate conversion coating designed for anti-corrosion, anti-fretting, and mounting properties. In this study, different conversion layers, like zinc-calcium phosphate, manganese-phosphate and tr

The method is based on the use of surface plastic exposure with the subsequent realization of the effect of thermal return of a thin surface layer. A number of most important descriptors of friction ensuring a durability of tribosystems in extreme conditions was considered. Basing of the laws of solid mechanics, principles of material sci

Abstract:

Catastrophic and premature bearing failure caused by excessive thermally-induced bearing preload is a major design problem for spindle bearings in high-speed machine tools. Due to a lack of low cost and easy to maintain on-line preload measuring techniques, the traditional solution is to limit the maximum spindle speed and the initial bearing preload. This solution is incompatible with the trend of high-speed machining, which requires increasing both spindle speed and spindle stiffness. Therefore, it would be valuable if thermally-induced preload can be monitored on-line for regulating bearing

Abstract:

Plain bearings are an important part of many large and critical units and assemblies used in the mining industry. They are widely used in power equipment, powerful pumps, compressors, electric motors and internal combustion engines (ICE). Plain bearings usually include an anti-friction bushing, part of the shaft surface (bearing journal) and an oil layer between them. These are complex and critical parts in which dangerous defects may occur and which directly affect the durability, accuracy and reliability of the entire assembly. To ensure high reliability of equipment with plain bearings used
