Impembelelo yobushushu obuphezulu okanye obuphantsi kwizixhobo zeroller chain
Kwimisebenzi yemizi-mveliso, iiroller chains, njengecandelo elibalulekileyo lokudlulisa, zisetyenziswa kakhulu kwizixhobo ezahlukeneyo zoomatshini kunye nemigca yemveliso. Nangona kunjalo, iindawo zokusebenza ezahlukeneyo zinemfuno ezahlukeneyo zokusebenza kweeroller chains, ingakumbi kwiindawo ezinobushushu obuphezulu okanye obuphantsi, ukusebenza kwezinto zeroller chain kuya kutshintsha kakhulu, nto leyo echaphazela ngokuthe ngqo ubomi benkonzo kunye nokuthembeka kweeroller chains. Eli nqaku liza kuphonononga impembelelo yeendawo ezinobushushu obuphezulu okanye obuphantsi kwizixhobo zeroller chain ngobunzulu, kwaye libonelele abathengi bamazwe ngamazwe ngobuninzi ngesalathiso sokukhetha izixhobo ezifanelekileyo zeroller chain.

1. Isishwankathelo sezixhobo ze-roller chain
Iiroller chains zihlala zenziwe ngentsimbi yekhabhoni, intsimbi ye-alloy, intsimbi engatyiwayo nezinye izinto. Intsimbi yekhabhoni ineempawu zokuba nexabiso eliphantsi kunye namandla aphezulu, kodwa ayinamandla okuxhathisa ukugqwala kunye nokumelana nokugqwala; intsimbi ye-alloy iphucula amandla, ukuqina kunye nokumelana nokugqwala kwezinto ngokongeza izinto ezixutyiweyo ezifana ne-chromium, i-nickel, i-molybdenum, njl.njl.; intsimbi engatyiwayo inokumelana nokugqwala okuhle kakhulu, ukumelana nokugqwala kunye namandla aphezulu, kwaye ifanelekile kwiindawo zokusebenza ezinzima.

2. Impembelelo yobushushu obuphezulu kwizixhobo zeroller chain
(I) Utshintsho kumandla ezinto eziphathekayo
Njengoko ubushushu bunyuka, amandla ezinto ze-roller chain aya kuncipha kancinci kancinci. Umzekelo, amandla e-general carbon steel chain aqala ukwehla kakhulu xa ubushushu budlula i-200°C. Xa ubushushu bufikelela ngaphezulu kwe-300°C, ukuncipha kobulukhuni namandla kuya kuba yinto ebalulekileyo, nto leyo ebangela ubomi benkonzo ye-chain bufutshane. Oku kungenxa yokuba ubushushu obuphezulu buya kutshintsha isakhiwo se-lattice sezinto zesinyithi, buthathaka amandla okubopha phakathi kwee-athomu, kwaye ngaloo ndlela bunciphise amandla okuthwala umthwalo wezinto.
(ii) Isiphumo sokumelana ne-oxidation
Kwiindawo ezinobushushu obuphezulu, izinto ze-roller chain zidla ngokuchaphazeleka zii-oxidation reactions. Ii-carbon steel chains zisabela ngokulula kwi-oxygen ukuze zivelise i-iron oxide kumaqondo obushushu aphezulu, ezingadli nje kuphela izinto ngokwazo, kodwa zenza umaleko we-oxide kumphezulu we-chain, nto leyo ebangela ukwanda kwe-friction coefficient ye-chain kunye nokunyuka kokuguguleka. Ii-stainless steel chains, kuba ziqulathe izinto ze-alloy ezifana ne-chromium, zinokwenza ifilimu ye-chromium oxide exineneyo kumphezulu, enokuthintela ngempumelelo i-oxygen ekubeni iqhubeke nokuchitha ingaphakathi le-material, ngaloo ndlela iphucula ukumelana kwe-oxidation ye-chain.
(iii) Iingxaki zokuthambisa
Amaqondo obushushu aphezulu anokutshintsha ukusebenza kweoyile yokuthambisa okanye igrisi. Kwelinye icala, i-viscosity yeoyile yokuthambisa iya kuncipha, isiphumo sokuthambisa siya kuwa, kwaye ayiyi kukwazi ukwenza ifilimu yokuthambisa esebenzayo kumphezulu we-friction pair ye-chain, nto leyo ebangela ukwanda kokuthambisa kunye nokuguguleka okugqithisileyo; kwelinye icala, igrisi inokunyibilika, iphele okanye itshise, ilahlekelwe sisiphumo sayo sokuthambisa, kwaye ikhawulezise ukuguguleka kwe-chain. Ke ngoko, xa usebenzisa ii-roller chain kwiindawo ezinobushushu obuphezulu, kuyimfuneko ukukhetha ii-lubricants ezifanelekileyo kwiimeko zobushushu obuphezulu kwaye wonyuse i-lubrication frequency.
