Trajektorija gibanja vretena ostrilnega stroja
Sebastjan Matkovič, Robert Kunc
Magistrsko delo
Oznake: magistrske naloge;tračne žage;ostrenje;oblika zob;procesiranje posnetkov;zaznavanje robov;trajektorija;
Uporabniki nizkocenovnih ostrilnih strojev orodji tračnih žag poročajo o težavah zaradi nemožnosti kakovostnega in ekonomsko sprejemljivega ostrenja orodji tračnih žag. Torej težave nastopajo tudi zaradi neustrezne programske opreme za upravljanje ostrilnih CNC - strojev. V magistrskem delu je preds ...

Effects of slide-to-roll ratio and temperature on the tribological behaviour in polymer-steel contacts and a comparison with the performance of real-scale gears
Sebastjan Matkovič, Mitjan Kalin
Izvirni znanstveni članek
Oznake: polymers;POM;steel;gears;slide-to-roll ratio (SRR);wear;friction;
Gearboxes that employ polymer gears are being used in an ever-increasing number of different applications. However, polymer-gear design suffers from a lack of understanding of their tribological behaviour under controlled - but at the same time realistic - conditions. One of the factors that is ofte ...

Effect of the coefficient of friction on gear-tooth root fatigue for both dry and lubricated running polymer gears
Sebastjan Matkovič, Mitjan Kalin
Izvirni znanstveni članek
Oznake: polymer gears;fatigue;friction;temperature;
Polymer gears are increasingly popular for a variety of applications due to their improved performance, light weight, ease of manufacture and low cost. However, the design of polymer gears and predictions of their useful operating lifetimes require refinements based on a better understanding of all ...

Effect of tribological properties on tooth root fatigue failure of polymer gears
Sebastjan Matkovič, Mitjan Kalin
Doktorska disertacija
Oznake: dissertations;polymers;tribology;friction;gears;tooth root;fatigue;
V zadnjih letih se je uporaba polimernih zobnikov v različnih aplikacijah, od avtomobilske industrije do gospodinjskih aparatov in industrijskih strojev, močno povečala. Povečanje uporabe polimernih zobnikov na vse več področjih je posledica materialnih lastnosti, kot so majhna masa, enostavna izdel ...

Tribological behaviour of green wood-based unrecycled and recycled polypropylene composites
Petra Jan, Sebastjan Matkovič, Marko Bek, Lidija Slemenik Perše, Mitjan Kalin
Izvirni znanstveni članek
Oznake: wear;polypropylene;bio composite;wood fillers;recycling;sustainability;
In this study we evaluated the tribological performance of polypropylene composites with wood-flour fillers obtained as a by-product from the wood-processing industry, which were based on unrecycled and recycled polypropylene polymer matrices. The mechanical properties of polypropylene-wood composit ...

Long-term creep compliance of wood polymer composites: using untreated wood fibers as a filler in recycled and neat polypropylene matrix
Marko Bek, Alexandra Aulova, Klementina Pušnik, Sebastjan Matkovič, Mitjan Kalin, Lidija Slemenik Perše
Izvirni znanstveni članek
Oznake: lesno-polimerni kompoziti;lezenje;vzdržljivost;les;recikliranje;wood–polymer composites;creep;durability;wood;recycling;
Neat (NPP) and recycled (RPP) polypropylene matrix materials were used to prepare wood–polymer composites with untreated wood fibers up to 40 wt.%. Long-term creep properties obtained through the time-temperature superposition showed superior creep resistance of composites with NPP matrix. In part, ...
