I-roller chain igcina njani ukusebenza kwayo kwindawo enobushushu obuphezulu?
Kubalulekile ukugcina ukusebenza kwetyathanga le-roller kwindawo enobushushu obuphezulu kuba isetyenziswa kakhulu kwizixhobo ezinobushushu obuphezulu ezifana nezitofu zemizi-mveliso kunye neenjini, kwaye ukusebenza okuqhelekileyo kwezi zixhobo kuxhomekeke ekusebenzeni okuzinzileyo kwetyathanga le-roller. Ezi zilandelayo ziindlela eziphambili zokugcina ukusebenza kwetyathanga le-roller kwindawo enobushushu obuphezulu:

Ukukhethwa kwezinto kunye nonyango
1. Khetha izinto ezimelana nobushushu obuphezulu
Ukukhethwa kwezinto ezisetyenziswa kwiitsheyini eziqengqelekayo sisiseko sokugcina ukusebenza kwazo kwiindawo ezinobushushu obuphezulu. Izinto ezisetyenziswa rhoqo ezixhathisa ubushushu obuphezulu ziquka intsimbi ye-alloy kunye nentsimbi engagqwali. Intsimbi ye-alloy inokuphucula kakhulu ukumelana kwayo nobushushu kunye nokumelana ne-oxidation ngokongeza izinto ze-alloy ezifana ne-nickel kunye ne-chromium, ukuze ikwazi ukugcina amandla kunye nokuqina okuhle kubushushu obuphezulu. Iitsheyini zentsimbi engagqwali zineengenelo zokuxhathisa i-asidi, ukumelana ne-alkali, ukumelana nokubanda kunye nobushushu, kwaye zisetyenziswa kakhulu kwiimeko zobushushu obuphezulu nobuphantsi. Umzekelo, ezinye iitsheyini zobushushu obuphezulu zisebenzisa izinto ezikhethekileyo ze-alloy ezinokugcina ukuthambisa okuzinzileyo kunye neempawu zokuguguleka kuluhlu lobushushu oluqala kwi--10℃ ukuya kwi-230℃

2. Inkqubo yokunyanga ubushushu
Inkqubo yokunyanga ubushushu inokuphucula ulwakhiwo lwe-microstructure kunye neempawu zoomatshini zezinto ze-roller chain kwaye izilungelelanise neendawo ezinobushushu obuphezulu. Iinkqubo eziqhelekileyo zokunyanga ubushushu ziquka ukufakelwa, unyango lwesisombululo, unyango lokwaluphala, ukulungisa nokucima. Umzekelo, ukucima ipleyiti ye-roller chain kunokuphucula ubulukhuni bomphezulu wayo kunye nokumelana nokuguguleka, okwenza ukuba ingagugi kwaye ingabi nakuguquka kubushushu obuphezulu. Ukongeza, unyango lobushushu lunokususa uxinzelelo ngaphakathi kwezinto kwaye luthintele umonakalo wokudinwa obangelwa luxinzelelo lobushushu kwiindawo ezinobushushu obuphezulu.

Ukuthambisa kunye nokugcinwa

1. Sebenzisa ii-lubricants ezimelana nobushushu obuphezulu
Izinto zokuthambisa zidlala indima ebalulekileyo ekusebenzeni kwee-roller chain, ingakumbi kwiindawo ezinobushushu obuphezulu. Izinto zokuthambisa ezimelana nobushushu obuphezulu zinokugcina ukusebenza kakuhle kokuthambisa kubushushu obuphezulu kwaye azilula ukuzenza ziguquguquke okanye zonakale. Umzekelo, ukusetyenziswa kwe-NSF-H1 grade lubricants akulunganga kuphela kwiindawo ezinobushushu obuphezulu, kodwa kukwasebenza kakuhle xa i-chain kunzima ukuyibonelela ngeoyile. Ukongeza, izinto zokuthambisa zinokwenza ifilimu ekhuselayo kumphezulu we-roller chain, zinciphise ukungqubana nokuguguleka, kwaye zandise ubomi benkonzo ye-chain.

2. Ukugcinwa nokuhlolwa rhoqo
Ukugcinwa rhoqo kunye nokuhlolwa kwee-roller chain yindlela ebalulekileyo yokuqinisekisa ukusebenza kwazo okuzinzileyo kwiindawo ezinobushushu obuphezulu. Ukugcinwa kuquka ukucoca ioyile kunye nokungcola kumphezulu we-chain, ukujonga ukuqina kunye nokuguguleka kwe-chain, kunye nokulungisa nokutshintsha iindawo eziguguleke kakhulu ngexesha elifanelekileyo. Umzekelo, i-chain iya kwandiswa ngenxa yokuguguleka ngexesha lokusebenza. Xa i-chain yolulwe ngaphezulu kwe-3%, i-chain kufuneka itshintshwe ngexesha. Ukuhlolwa rhoqo kunokufumanisa iimpazamo ezinokubakho, njengokugoba nokujika kwe-chain, ukuthintela iimpazamo ezinkulu ezifana nokuqhekeka kwiindawo ezinobushushu obuphezulu.

Ukulungiswa koyilo lwesakhiwo

1. Yandisa amandla okuxinana kwetsheyini

Kwiindawo ezinobushushu obuphezulu, amandla e-roller chain aya kuchaphazeleka ukuya kuthi ga kwinqanaba elithile, ngoko ke kuyimfuneko ukukhulisa amandla ayo okutsalwa ngokusebenzisa uyilo lwesakhiwo. Umzekelo, yonyusa ubukhulu bepleyiti ye-chain yangaphakathi ukuqinisekisa amandla okutsalwa kwe-chain. Ukongeza, ii-pins kunye nee-sleeves ezinamandla aphezulu zingasetyenziselwa ukuphucula amandla okuthwala umthwalo we-chain. Ii-pins ezinamandla aphezulu zinokudlulisela amandla ngcono, ngelixa ii-sleeves kufuneka zibe nokumelana okuhle kokuguguleka kunye nemiphumo yokuthambisa.

2. Cinga ngezinto zokwandisa ubushushu

Kwiindawo ezinobushushu obuphezulu, i-coefficient yokwandiswa kobushushu ye-roller chain iya kutshintsha, nto leyo enokubangela iingxaki ezifana nokungalingani kobukhulu be-chain kunye noxinzelelo. Ke ngoko, xa uyila i-roller chain, kuyimfuneko ukuqwalasela ngokupheleleyo i-thermal expansion factor, ukucwangcisa ngokufanelekileyo i-pitch kunye nobude be-chain, kunye nokuqinisekisa uzinzo olulinganayo kunye nokuchaneka kokudluliselwa kwe-chain kubushushu obuphezulu. Umzekelo, kwii-stainless steel chains, xa ubushushu obujikeleze umhlaba budlula i-400°C, kufuneka kunikwe ingqalelo ekhethekileyo kutshintsho lwe-gap olubangelwa kukwanda kobushushu.

Ukuphucula ukulungelelaniswa kwendalo
1. Amanyathelo okulwa ne-oxidation kunye nokulwa nokugqwala
Indawo enobushushu obuphezulu iya kukhawulezisa inkqubo yokubola kunye nokubola kwee-roller chains, ngoko ke kufuneka kuthathwe amanyathelo okulwa nokubola kunye nokubola. Umzekelo, unyango lomphezulu wee-roller chains, ezifana ne-nickel plating, i-Dacromet, i-phosphating, njl.njl., zinokwenza umaleko okhuselekileyo wokuthintela ukubola kunye nokubola kumaqondo obushushu aphezulu. Ukongeza, i-anti-oxidation coating ingafakwa kumphezulu we-chain ukuphucula ngakumbi ukumelana kwayo nobushushu obuphezulu.

2. Uyilo olukhethekileyo lokuziqhelanisa neemeko ezinzima
Kwiindawo ezinobushushu obuphezulu, iiroller chains zinokujongana nezinye iimeko ezinzima, ezinje ngokufuma, uthuli, ioyile, njl. Ke ngoko, iiroller chains kufuneka zibe nokuguquguquka okuhle kokusingqongileyo. Umzekelo, yila isakhiwo seroller esisebenza kakuhle ekutywineni ukuthintela uthuli kunye neoyile ukuba ingangeni kwiroiler kwaye ichaphazele ukusebenza kwayo okuqhelekileyo. Kwangaxeshanye, iindlela ezikhethekileyo zokuthambisa ezifana ne-oyile bath lubrication okanye i-pressure cycle lubrication nazo zingasetyenziselwa ukuziqhelanisa nobushushu obuphezulu kunye neendawo ezinzima.

Isishwankathelo
Isitshixo sokugcina ukusebenza kwee-roller chain kwiindawo ezinobushushu obuphezulu sikwimilinganiselo ebanzi efana nokukhethwa kunye nokucubungula izinto, ukuthambisa kunye nokugcinwa, ukwenziwa ngcono koyilo lwesakhiwo, kunye nokuphucula ukuguquguquka kwendalo. Ngokukhetha izinto ezinobushushu obuphezulu, ukwamkela iinkqubo ezifanelekileyo zonyango lobushushu, ukusebenzisa ii-lubricants ezinobushushu obuphezulu, ukugcinwa rhoqo kunye nokuhlolwa, ukuphucula amandla okuxinana kwe-chain, ukuqwalasela izinto zokwandisa ubushushu, ukuthatha amanyathelo okulwa ne-oxidation kunye nokulwa nokugqwala, kunye noyilo olukhethekileyo olulungelelaniswe neendawo ezinzima, ii-roller chain zinokugcina ukusebenza okuzinzileyo kwiindawo ezinobushushu obuphezulu, ukuqinisekisa ukusebenza okuqhelekileyo kwezixhobo zoomatshini kunye nenkqubela phambili egudileyo yemveliso yemizi-mveliso. Ngophuhliso oluqhubekayo lwesayensi yezinto kunye nobuchwepheshe bobunjineli, ukusebenza kwee-roller chain kwiindawo ezinobushushu obuphezulu kuya kuphucuka ngakumbi, kubonelela ngeziqinisekiso ezithembekileyo ngakumbi zokusebenza kwezixhobo ezinobushushu obuphezulu.
