In the first part of the paper we present the reasons for the occurrence of particles in a hydraulic fluid. The problem of using a standardized test dust due to its abrasiveness, which is much …
The article describes a web controlled pneumatic press as an example of a system designed to demonstrate the control of pneumatic devices via the Global Area Network (GAN).
When the situation with COVID-19 demanded closing nursery schools, primary and secondary schools, high schools, universities and colleges, and therefore demanded distance learning, the situation seemed complicated.
Reliable polymer gear design remains to date an open challenge due to a lack of data regarding the specific properties of polymer materials and due to complex relationships between the gears’ geometric parameters and the applied running loads.
In the first part of the paper, the reasons for the appearance of particles inside the hydraulic liquid are presented. These are the four possible types of wear, two-body abrasive wear, three-body abrasive wear, erosion and cavitation.
Submerged arc welding is one of most productive arc welding processes. In combination of narrow gap weld groove besides high melting rate, superior weld quality and…
Durability testing of polymer gears and integration of material database for more advanced calculation of power train application
In the past decades, polymer materials have been increasingly used in gears. There is lack of fatigue data, such as Woehler diagrams, wear coefficients of polymer gear pairs which allow…
Internal leakage occurs in a lot of hydraulic components; pumps, hydromotors, spool sliding valves. Inside of them a gap exists between the two elements with relative velocities.
Characterization of the surface topography of materials is important in applications involving friction, lubrication, and wear. The essential feature is the hardness of materials.
The viscosity of a hydraulic fluid is one of its most important material properties. The choice of the appropriate viscosity of the fluid for a particular application is one of the most important tasks of a hydraulic engineer.
