The Economic Validity of Bearing Structure Reparation

Abstract

The arhaic elements of bearing structure or absence of them on the market are some of the reasons why observers of technical systems often decide for reparation or reconstruction of that spent systems fraction. From the aspect of economics, the specific meaning has the backing of primary geometrics and kinematic characteristics on spent parts in relation with buying new equipments. The aim of the work was to indicate on economical validity of applying reparation in reconstruction of damaged and spent fraction of shaft and roller bearing, with detail description of reparation process the often used in practical work.

Zastarelost elemenata ležišnog sklopa ili nedostatak istih na tržištu su neki od razloga zbog kojih se održavaoci tehničkih sistema najčešće odlučuju na popravku ili obnavljanje tih istrošenih delova sistema. Sa aspekta ekonomičnosti, od naročitog je značaja vraćanje prvobitnih geometrijskih i kinematskih karakteristika na istrošenim delovima u odnosu na kupovinu nove opreme. Cilj rada je bio da se ukaže na ekonomsku opravdanost primene reparacije u obnavljanju oštećenih i istrošenih delova vratila i kotrljajnih ležaja, sa detaljnim opisom postupaka reparacije najčešće primenjivanih u praksi.
