Okokuqala, qonda: Yintoni unobangela oyintloko wokuguqulwa kwe-roller chain welding?

Ngaphambi kokuba siyile isixhobo, kufuneka siqale siqonde isizathu esiyintloko sokuguqulwa kwe-roller chain welding—ukukhululwa koxinzelelo okubangelwa kukungena kobushushu okungalinganiyo kunye nokungathintelwa ngokwaneleyo. Iikhonkco ze-roller chain zihlala ziquka iipleyiti zangaphandle nezangaphakathi, ii-pin, kunye nee-bushings. Ngexesha lokudityaniswa, ukufudumeza okucwangcisiweyo kusetyenziswa ikakhulu kunxibelelwano phakathi kweepleyiti, ii-pin, kunye nee-bushings. Izizathu eziphambili zokuguqulwa ngexesha lale nkqubo zingashwankathelwa ngolu hlobo lulandelayo:

Ukusasazwa koxinzelelo lobushushu olungalinganiyo: Ubushushu obuphezulu obuveliswa yi-welding arc bubangela ukwanda ngokukhawuleza kwesinyithi kwindawo ethile, ngelixa iindawo ezingafudunyezwanga ezingqongileyo, ngenxa yobushushu bazo obuphantsi kunye nokuqina okukhulu, zisebenza njengesithintelo, zithintela isinyithi esishushu ukuba singakhuli ngokukhululekileyo kwaye sivelise uxinzelelo oluxinzelelweyo. Ngexesha lokupholisa, isinyithi esishushu siyancitshiswa, esithintelwa ziindawo ezingqongileyo, nto leyo ebangela uxinzelelo lokuxinana. Xa uxinzelelo ludlula inqanaba lemveliso yezinto, kwenzeka ukuguquka okungapheliyo, njengeekhonkco ezigobileyo kunye neephini ezingalungelelaniswanga kakuhle.

Ukuchaneka kokubekwa kwecandelo okunganelanga: I-roller chain pitch kunye ne-link parallelism zizibonakaliso eziphambili zokuchaneka. Ukuba ireferensi yokubekwa kwecandelo kwi-fixture ayicacanga ngaphambi kokuwelda kwaye amandla okubamba awazinzile, ii-components zisengozini yokungahambi kakuhle ecaleni okanye kwi-longitudinal phantsi kwesenzo soxinzelelo lobushushu ngexesha lokuwelda, okubangela ukuphambuka kwepitch kunye nokuphazamiseka kwe-link. Ukuhambelana okungekho kakuhle phakathi kokulandelelana kokuwelda kunye ne-fixture: Ukulandelelana kokuwelda okungafanelekanga kunokubangela ukuqokelelwa kobushushu kwindawo yokusebenza, okwandisa ukuguquguquka kwendawo. Ukuba i-fixture ayiboneleli ngemida enamandla ngokusekelwe kulandelelwano lokuwelda, ukuguquguquka kuya kuba nzima ngakumbi.

Okwesibini, imigaqo ephambili yoyilo lwezixhobo zokuwelda: indawo echanekileyo, ukubopha okuzinzileyo, kunye nokusasazwa kobushushu okuguquguqukayo.

Ngenxa yeempawu zesakhiwo see-roller chain (izinto ezininzi kunye neepleyiti ze-chain ezibhityileyo, eziguquka lula) kunye neemfuno ze-welding, uyilo lwe-fixture kufuneka lunamathele kwimigaqo emithathu ephambili yokulawula ukuguqulwa komthombo:
