Idler Caterpillar 600-8739 za mačka 6015

V gradbeništvu se gosenice v prostem teku pogosto zapirajo med različnimi gradbenimi mesti z bagerji, kot so kopanje temeljnih jame in nošenje gradbenih materialov . Tempo gradbeništva tukaj je tesen, oprema pa se začne in ustavi, zato morajo prodajna kolesa nositi neenakomerne obremenitve in udarne sile, ustvarjene .

Pri obsežnih infrastrukturnih gradbenih projektih, kot so mostovi in ​​predori, so zemeljski pogoji zapleteni in spremenljivi, in lahko obstaja velika količina gradbenih odpadkov, kot so gramoz in jeklene palice . Ti odpadki bodo povzročili obrabo na tiru in vplivali na delovanje idlerja, ki se ukvarjajo z gradbenimi materiali, med konstrukcijo, kot je konstrukcijo, kot je bilo, da se med gradnjo, kot so konstrukcije, pa se med gradnjo, ki se nanašajo na gradbeništvo. kolesa, povečanje tekaškega upora in postavljanje višjih zahtev za čiščenje in vzdrževanje koles IDL .

Rudarsko okolje je eden najtežjih izzivov, s katerimi se sooča idler Caterpillar 6015. rudarske operacije se običajno izvajajo v odprtem ali podzemlju . v rudnikih odprtih pit je oprema izpostavljena soncu in dežju dolgo časa {{3}. Surface . podzemne mine se soočajo s težavami, kot so majhen prostor, slabo prezračevanje in visoka koncentracija prahu .

During the mining process, the excavator needs to dig hard rocks or ores. The huge digging force is transmitted to the idler through the crawler, which makes it bear great impact and tension. At the same time, rock fragments, slag, etc. in the mine are easy to splash around the idler, and even enter the gap between the idler and the crawler, aggravating obraba . Poleg tega gibanje opreme v rudarskih operacijah pogosto spremljajo veliki izboklini in vibracije, kar je tudi hud test za priključne dele in celotno strukturno trdnost idlerja .

Na vročih puščavskih območjih ali na zunanjih gradbenih mestih poleti vpliva visoke temperature na gosenice v prostem teku ni mogoče podcenjevati . visoka temperatura bo pospešila oksidacijo in izhlapevanje maščobne maščobe, kar bo mazanje postopoma poslabšalo, kar ima za posledico povečano trenje med komponenta

Moreover, metal parts will expand under high temperature, which may cause the clearance between the idler and the track to change, affecting the normal operation of the equipment. In outdoor operations, the idler will be exposed to strong sunlight for a long time, and the surface temperature will rise sharply, which will not only reduce the strength of the material, but also cause the seal to age and deform, causing oil leakage and other problems, affecting the service life and reliability of the idler .

During winter construction in cold northern regions, idler caterpillars face many problems caused by low temperatures. In extremely cold weather, the viscosity of the lubricating oil will increase significantly, resulting in increased resistance when the idler pulley rotates and difficulty in starting. In addition, metal materials will become brittle and hard at low temperatures, and their impact resistance will decrease, increasing the risk of the idler Razbijanje jermenic, ko jih prizadenejo zunanje sile .

In addition, in cold environments, the rubber parts of the tracks and idlers will become stiff and less elastic, affecting their fit with the ground and the idlers, which in turn reduces the driving stability and operating efficiency of the equipment. At the same time, in order to ensure the construction progress, the equipment often needs to be put into operation without being fully preheated, which is a great challenge to the performance and service life of the idlers .
