Siyini isizathu salokhu kulimala kwangaphambi kwesikhathi kuma-roller bearings?Umhleli olandelayo uzokutshela izizathu eziyinhloko zokwehluleka kwangaphambi kwesikhathi kwalokhu kuthwala kwerola ene-tapered:

(1) Ukuqina kwendandatho yokuthwala akuhambisani nobulukhuni berola.Ukuqina kwendandatho yangaphakathi kuphakeme kancane kunokwerola, okuthuthukisa ikhono lomjaho wangaphakathi wendandatho ukushiya unqenqema bese ucindezela ku-roller.

(2) Ukuthintana phakathi kwerola kanye nomzila womjaho werola ene-tapered ngaphansi kwesimo sikaziro kuwukuthinta umugqa.Ngenxa yokuthi umzila womjaho wendandatho yangaphakathi uphansi futhi ushiywe, ukuxhumana phakathi kwerola nerola kuyashintsha ukusuka koxhumene naye kulayini kuya koxhumene naye.Iphoyinti lokuxhumana eliseduze.Ngakho-ke, lapho i-bearing isebenza, ama-roller ayo angaphansi kokucindezeleka okukhulu kwe-shear, okuholela ekugxilweni kokucindezeleka.Lapho ukucindezeleka kwe-shear kudlula umkhawulo wokukhathala wezinto ezibonakalayo, ukuqhekeka kokukhathala kwenzeka.Ngesenzo sokulayisha okujikelezayo, imifantu yokukhathala isakazeka eduze kwemingcele yokusanhlamvu futhi yakha i-spalling, okuholela ekuhlulekeni kokuqala kokukhathala kokuthwala.

(3) Unqenqema lokugaya lwerola elicijile elithwele umzila womjaho wangaphakathi weringi libangelwa ukulungiswa okungafanele kwendawo yokubopha yomgwaqo kanye nesondo lokugaya ngesikhathi sokugaya okokugcina komzila womjaho wangaphakathi, noma ukukhetha okuncane kwesondo lokugcina lokugaya. ububanzi.

Kusukela ekuhlaziyweni okungenhla, kungabonakala ukuthi i-roller ene-tapered ephethe lapha ayiphumeleli ngenxa yonqenqema olusele kumzila womjaho wangaphakathi wendandatho phakathi nenqubo yokugaya indandatho engaphakathi ephethe.Ngakho-ke, phakathi nenqubo yokugaya yomjaho wendandatho yangaphakathi, ububanzi besondo lokugaya kufanele kukhethwe kahle futhi indawo yokubopha yomjaho wangaphakathi wendandatho kanye nesondo lokugaya kufanele kube nembayo ukuze kugwenywe ukukhiqizwa konqenqema lwendandatho yangaphakathi, ngaleyo ndlela. ukugwema ukwehluleka kokuqala kokuthwala.
