Distance Learning Opportunities. Will we be Able to Use Them in Future?
Dr. Vesna Trančar, univ. dipl. inž., ŠC Ptuj Abstract: 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...

Narrow gap submerged arc welding of heavy wall stainless steel forgings
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 of hydraulic Components
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.
Analysis parameters of laser hardening on robot cell
Characterization of the surface topography of materials is important in applications involving friction, lubrication, and wear. The essential feature is the hardness of materials.
Influence of the viscosity index of different hydraulic fluids on the operating temperature range
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.
Development and research of the prototype of the Stewart platform
Simulations of human emotions under real conditions are very popular nowadays. A simulation of six degrees of freedom was made possible by the development of the Gough-Stewart platform in 1947. The electrically driven miniature Stewart platform…
S-Gear Design Rules
Gears featuring the curved path of contact were implemented in heavy industry where it was proven that such gears can successfully replace involute gears. Purely graphical method of design was later replaced by an analytical definition…
