Uthini umahluko phakathi kwe 40 kunye ne 41 roller chain?

Ukuba ukwimarike yokurhweba koomatshini bakho bomzi-mveliso, usenokuba uye wadibana namagama “amatsheyina angama-40” kunye “netsheyini yokuqengqeleka engama-41.” Ezi ntlobo zimbini ze-roller chain ziqhele ukusetyenziswa kwizicelo ezahlukeneyo, kodwa yintoni ezahlulayo? Kule bhlog, siza kuphonononga umahluko phakathi kwe-40 kunye ne-41 roller chain ukukunceda wenze isigqibo esinolwazi malunga neemfuno zakho ezithile.

Okokuqala nokuphambili, kubalulekile ukuqonda ukuba zombini i-40 kunye ne-41 roller chain ziyinxalenye ye-ANSI (i-American National Standards Institute) yochungechunge oluqhelekileyo lwe-roller. Oku kuthetha ukuba zenziwa kwimilinganiselo ethile kunye nemigangatho yomgangatho, okwenza ukuba zitshintshwe kunye namanye amatyathanga asemgangathweni we-ANSI. Nangona kunjalo, nangona ukufana kwabo, kukho ukungafani okuphambili okubeka i-40 kunye ne-41 i-roller chain ngaphandle.

Omnye umahluko ophambili phakathi kwe-40 kunye ne-41 ye-roller chain ilele kwi-pitch yabo. I-pitch yetsheyini eqengqelekayo ibhekisa kumgama phakathi kwamaziko ezikhonkwane ezikufutshane, kwaye idlala indima ebalulekileyo ekumiseleni amandla ekhonkco kunye nomthamo wokuthwala umthwalo. Kwimeko ye-40 ye-roller chain, i-pitch ilinganisa i-intshi ye-0.5, ngelixa i-pitch ye-41 roller chain incinci kwi-intshi ye-0.3125. Oku kuthetha ukuba i-40 i-roller chain ifaneleka ngakumbi kwizicelo ezifuna amandla aphezulu kunye nokuqina, ngelixa i-41 i-roller chain ingaba yinto efanelekileyo yokusetyenziswa kwe-lighter-duty.

Ukongeza kwi-pitch, enye into ebalulekileyo ekufuneka iqwalaselwe xa uthelekisa i-40 kunye ne-41 roller chain ngamandla abo ahlukeneyo. Amandla e-tensile abhekiselele kubuninzi boxinzelelo lwe-tensile into enokumelana nayo ngaphandle kokwaphuka, kwaye yingqwalasela ebalulekileyo ekumiseleni ukufaneleka kwekhonkco le-roller kwisicelo esinikiweyo. Ngokubanzi, i-40 i-roller chain ivame ukuba namandla aphezulu xa kuthelekiswa ne-41 ye-roller chain, okwenza kube yinto ekhethiweyo yokukhetha izicelo ezinzima apho ikhonkco iya kuba phantsi kwemithwalo ebalulekileyo kunye nemikhosi.

Ngapha koko, imilinganiselo yamacandelo angama-40 kunye nama-41 ahluka kancinci. Ngokomzekelo, i-diameter ye-roller kwi-40 ye-roller chain ngokuqhelekileyo inkulu kune-41 ye-roller chain, evumela uqhagamshelwano olungcono kunye nokuzibandakanya kunye ne-sprockets. Lo mahluko kubungakanani be-roller unokuchaphazela ukusebenza ngokubanzi kunye nokusebenza kakuhle kwekhonkco kwizicelo ezahlukeneyo.

Olunye uqwalaselo olubalulekileyo xa ukhetha phakathi kwe-40 kunye ne-41 ye-roller chain kukufumaneka kwee-sprockets kunye nezinye izixhobo. Ekubeni i-40 i-roller chain isetyenziswa ngokuqhelekileyo kwimimiselo yezoshishino, kunokuba lula ukufumana uluhlu olubanzi lwee-sprockets ezihambelanayo kunye nezixhobo ze-40 roller chain xa kuthelekiswa ne-41 roller chain. Oku kunokuba yinto ebalulekileyo kwizicelo ezithile apho ubungakanani obukhethekileyo besprocket okanye uqwalaselo luyafuneka.

Ekugqibeleni, ukhetho phakathi kwe-40 kunye ne-41 roller chain luya kuxhomekeka kwiimfuno ezithile zesicelo sakho. Ukuba ufuna i-roller chain ekwazi ukuphatha imithwalo enzima kwaye inikeze ukusebenza okuthembekileyo kwiimeko ezifunekayo, i-40 roller chain ingaba yinto engcono. Kwelinye icala, ukuba isicelo sakho sibandakanya imithwalo ekhaphukhaphu kwaye ifuna uyilo oludityanisiweyo lwetsheyini, ikhonkco le-roller engama-41 inokufaneleka ngakumbi.

Ukuqukumbela, ngelixa i-40 kunye ne-41 i-roller chain zombini ziyinxalenye yoluhlu oluqhelekileyo lwe-ANSI, ziyahluka ngokwe-pitch, amandla okuqina, imilinganiselo yecandelo, kunye nokufaneleka kwesicelo. Ukuwuqonda lo mahluko kubalulekile ekukhetheni ikhonkco elifanelekileyo lomatshini wakho kunye nezixhobo. Ngokuqwalasela iimfuno ezithile zesicelo sakho kunye nokuqwalasela iimpawu ezizodwa zohlobo ngalunye lwe-roller chain, unokwenza isigqibo esinolwazi esiqinisekisa ukusebenza kakuhle kunye nokuthembeka. Nokuba ukhetha i-40 okanye i-41 roller chain, unokuthembela ukuba zombini iinketho zenziwe ngobunjineli ukuhlangabezana nomgangatho ophezulu kunye nemigangatho yokusebenza kwiimfuno zakho zoshishino.
