How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more
The study investigates the influence of the load distribution on lubricant film thickness between the rolling elements and raceways of the deep groove ball bearing using the conventional theory of elastohydrodynamic lubrication (EHL) with an applied original mathematical model of load distribution between the rolling elements developed by the autho...
Taguchi method has been used to analyse the influence of the coefficient of the trochoid radius, the number of revolutions and the working pressure on the change in the flow rate and the volumetric efficiency of the trochoidal rotary pump with internal gearing. The coefficient of the trochoid radius, as a geometrical parameter and the number of rev...
ABSTRAcT The timing belt drives are synchronous drives that transmit power and motion via side surfaces of belt teeth and, partially, through friction between belt teeth and belt pulley teeth. Failure of the timing belt drives occurs due to wear of its compo-nents. Analysis of process of friction, as a main cause of wear, is conducted based on coup...
The paper presents results of theoretical and experimental research into the scoring resistance of plane convex-concave gears. There are generalized basic relations of the integral temperature criterion for all kinds of path of contact in defined plane cylindrical gears given. Theoretically obtained relations are illustrated by the results of the s...
In case of contaminated machine environment with dust, sand or minerals, small solid debris particles could be involved into rolling bearing lubricant. Solid and very sharp non-metal particles cause intensive abrasive wear of rolling bearing parts. This process could leads to change of rolling bearing macro geometry and contact surfaces micro geome...
