Elements of power transmission and motion, bearings and couplings
No full textLežajevi i spojke neophodan su i neizostavan dio ukupne izvedbe, sigurnosti i
pouzdanosti pomoćnih brodskih strojeva te su potrebni da bi sustav ispravno radio i imao
dugačak životni vijek. Učinkovitost prijenosa snage povećava se adekvatno odabranim i
servisiranim ležajevima i spojkama te oni kao takvi pogoduju smanjenju vremena zastoja,
troškova održavanja te pozitivno utječu na sigurnost plovila i posljedično posade.
S druge strane, zanemarivanje i neadekvatno održavanje ovih komponenti uvelike
može dovesti do tehničke neučinkovitosti, ugrožene sigurnosti i neočekivanih poremećaja u
brodskim pomoćnim sustavima i uređajima, te puno većeg troška ili havarije u konačnici.Bearings and clutches are a necessary and indispensable part of the overall
performance, safety and reliability of marine auxiliary machinery. They are necessary for
the marine engine to work properly and have a long life. The efficiency of power
transmission is increased by adequately selected and serviced bearings and clutches, and as
such they favor the reduction of downtime, maintenance costs and have a positive effect on
the safety of the vessel and, consequently, the crew.
On the other hand, neglect and inadequate maintenance of these components can
greatly lead to technical inefficiency, compromised safety and unexpected disruptions in the
ship's auxiliary systems and devices, and a much higher cost or breakdown in the end
