Abstract

Trošenje je neizbježna pojava kod kontakta 2 ili više tijela u gibanju. Najčešće se definira kao negativna pojava jer dovodi do neželjenih stanja površina te gubitka materijala pa je potreban popravak ili zamjena istrošenih dijelova. Kako bi bolje shvatili i izbjegli neželjena trošenja razvila se znanstvena disciplina nazvana tribologija. Ona se bavi površinama u dodiru i relativnom gibanju te pratećim aktivnostima odnosno sveobuhvatno se bavi problemima trošenja i trenja.
Razvojem tehnologije i potrebom da se gledateljima prenese što realniji dojam uvode se noviteti u filmsku industriju u pogledu nove opreme. Time dolazi do izuma filmskih kranova koji omogućuju potpuno nove aspekte snimanja. Upotreba krana omogućuje nove kadrove, veći doseg, uklanjanje neželjene buke, veće brzine kretanja te mogućnost kretanja kamere u sve tri prostorne dimenzije
U ovom radu analizirat će se razlozi te mehanizmi trošenja koji su se pojavili na paru zupčanika elektromotora koji upravlja horizontalnim pomacima postolja kamera na kojem se nalazi kamera.

Abstract (english)

Wear is unavoidable interaction between 2 or more moving bodys in contact. Usually it is defined as undesired phenomenon which leads to unwanted surface conditions and loss of material therefor component needs to be fixed or replaced with a new one. In order to better understand and avoid unneccessary wear, a new scientific discipline called tribology has been developed. It is a discipline which includes interacting surfaces in relative motion.
Due to technology development and need for more realistic impression, innovations are introduced in the film industry in terms od the new equipment. Therefor film cranes are invented that allows completely new aspects of making movies. Utilization of crane enables new shots, greater reach, eliminates unwanted noise, higher speed of movement and ability to move the camera in all 3 dimensions.
In this work the reason of wear mechanisams has been analyzed which occured on pair of gears thar are in charge of horizontal camera movements.
