Kwimeko enzima yezityalo zesamente, ii-elevator zebhakethi azixhomekekanga kuphela kwiikhonkco eziqinileyo ezijikelezayo kodwa nakwizihlanganisi ezibalulekileyo ezisebenza njengonxibelelwano oluyimfuneko phakathi kwetshane kunye neebhakethi. Ezi zihlanganisi, zihlala zihambelana nemigangatho ye-DIN 745 kunye ne-DIN 5699, ziibhulorho zoomatshini ezidlulisela amandla okuphakamisa ukusuka kwitshanethi ukuya kwiibhakethi ezithwele izinto ezirhabaxa ezifana ne-clinker, i-limestone, kunye nomgubo oluhlaza.
Iinkokheli zoshishino ezifana ne-RUD, i-CICSA, kunye ne-Heko zinamava akhethekileyo kwezi zinto zenziwe ngobunjineli, zisebenzisa iinkqubo eziphambili zesinyithi kunye nonyango lobushushu ukwandisa ubomi benkonzo phantsi kweemeko ezinzima.
Uyilo oluqhelekileyo kunye nezicelo
Imigangatho emibini ephambili yokudibanisa ilawula ishishini lesamente:
- Iikhamandela ze-DIN 745inomzimba oqingqiweyo wohlobo lwe-U onepleyiti yomgama kunye nendibano yeenati, eyenzelwe iilifti zetyathanga eliphakathi ezisebenza ngokubanzi, ezinomthwalo omkhulu. Ezi ziqhagamshelo zincamathisela ngqo iibhakethi kwimicu yetyathanga.
- Iikhamandela ze-DIN 5699Inika iprofayili ethe tyaba kunye nejometri encinci, enezikhondo ezinde ezinemisonto ezivumela ukuba iipleyiti zomgama zifakwe phakathi kwebhakethi kunye netsheyini. Olu yilo lubonelela ngokhuseleko olungcono lokusebenza kunye nokumelana nokuqhekeka nokudinwa okuphuculweyo xa kuthelekiswa ne-DIN 745, nto leyo eyenza ukuba zifaneleke kwiindawo ezixineneyo zebhakethi kunye neelifti ze-PCD ezincitshisiweyo.
Zombini ezi migangatho zenzelwe ukusebenza ngokungenamthungo ngemicu yetyathanga ehambelana ne-DIN 764 kunye ne-DIN 766.
Inkqubo yoKhetho lweZinto kunye nokuQongwa
Ngokungafaniyo nevaliweyoiikhonkco ezijikelezileyo, izihlanganisiinoyilo oluvulekileyo olunephini elinqamlezileyo elisuswayo, nto leyo edala indawo yoxinzelelo oluqhelekileyo. Ukulungisa oku, izihlanganisi ezikumgangatho ophezulu ziveliswa ngokufaka ngokuchanekileyo amaconsi kusetyenziswa iintsimbi ze-alloy ezicolekileyo. Izinto eziqhelekileyo ziquka intsimbi engama-45# enyangwa bubushushu, ii-Cr-Mo (chromium-molybdenum), kunye neentsimbi ze-alloy ze-Cr-Ni-Mo (chromium-nickel-molybdenum). Udidi lwesihlanganisi olufunekayo lumisela ukhetho oluthile lwentsimbi ye-alloy. I-Drop forging ilungelelanisa ukuhamba kweenkozo kunye nomgca wesihlanganisi, nto leyo ephucula kakhulu ukumelana nokudinwa phantsi kwemithwalo eqhubekayo yokuxinana kunye nefuthe efunyanwa kwimisebenzi yesityalo sesamente.
Ukuqina Okubalulekileyo kunye noLawulo loMgangatho
Ukuqinisekisa ukuba izihlanganisi ziyanyamezela ukuguguleka okufana neekhonkco ezijikelezileyo ze-carburised, abavelisi abaphambili kushishino basebenzisa unyango olukhethekileyo lokuqinisa kwiindawo ezidibeneyo zokunxibelelana nekhonkco. Ezi zinokuhlulwa ngolu hlobo:
- Izihlanganisi eziqiniswe ngomphetho/eziqiniswe ngokungeniswa: Eziqiniswe ngokujikeleza ukuya kuthi ga kumandla okutsalwa kwezinto amalunga ne-950–1100 N/mm², kunye nokuqina kwe-inductive kwiindawo zoqhagamshelwano ezidibanisayo okufikelela kubunzima bomphezulu obuyi-600 HV1 (55HRC) ubuncinane.
- Izihlanganisi eziqinileyo/ezifakwe i-carburing: Kwizicelo ezirhabaxa kakhulu, abavelisi abanjengoPewag banikezela nge-carburing eyongezelelweyo, nto leyo efikelela kubunzima bomphezulu obuyi-750 HV1 okanye ngaphezulu kwiindawo zoqhagamshelwano phakathi kwe-interlink.
Iiparamitha zolawulo lomgangatho eziphambili ezichazwe ngabavelisi abakhulu ziquka ubunzulu bokuqina (≥0.1 × d), ubunzima bomphezulu (ubuncinci be-600–750 HV1), kunye namandla okuqinisekisa nokuqhekeza alingana okanye adlula lawo makhonkco makhulu ahambelana nawo. Uvavanyo oluqatha lweparamitha zomgangatho womphezulu kunye nonyango lobushushu luqinisekisa ukumelana nokudinwa okuqhubekayo kuzo zonke iibhetshi zemveliso.
Imingeni yokusebenza kunye nokutshintshwa kwayo
Nangona izihlanganisi zenziwe zaqina kwaye ziqine ngokukhethekileyo ukuze zifikelele kumandla ezihlanganisi ezijikelezileyo, zihlala zingoyena mmandla ubuthathaka kwinkqubo ngenxa yejiyometri yazo evulekileyo kunye nezibophelelo ezinemisonto. Indawo yoqhagamshelwano phakathi kwesihlanganisi kunye nesihlanganisi setyathanga yenye yezona ndawo zixineneyo kakhulu kwinkqubo yonke yelifti, okwenza kube lula ukuguga, ukudinwa, kunye nokukhukuliseka kwamandongomane phantsi kokungcangcazela okuqhubekayo.
Iindlela eziqhelekileyo zokungaphumeleli ziquka:
- Ukonakala komphezulu: Ukukrala kwiindawo zoqhagamshelwano ezidibanisayo, okunciphisa indawo esebenzayo yokunqumla
- Ukuqhekeka kokudinwa: Uxinzelelo olujikelezayo luqala ukuqhekeka kwiindawo zoxinzelelo, eziqhubeka ngokuhamba kwexesha de kwaphuke
- Ukukhululeka kwezibophelelo: Ukukhululeka kweenati okubangelwa kukungcangcazela, okuhlala kuncitshiswa ziinati ezizitshixayo okanye ii-spring washers
Ukunciphisa le mingcipheko, uqhagamshelo olunemisonto kufuneka luqiniswe ngeenkqubo ezifanelekileyo zokuthintela, kwaye iipleyiti zomgama kufuneka zifakwe ngokuchanekileyo. Ukusetyenziswa kweendibano ezizitshixayo kunye nokumelana nokungcangcazela okuqhubekayo kunye nemijikelo yobushushu ziimpawu ezibalulekileyo zoyilo lobomi obude benkonzo.
Amava oshishino abonisa ukuba nangona ityathanga ngokwalo linokuba nobomi benkonzo obulinganiswa ngamakhulu amawaka eetoni ezithuthwayo, izincamathelisi zebhakethi kunye nezihlanganisi zinokufuna ukutshintshwa kwangoko kakhulu. Olunye ulwazi lwasentsimini lubonisa ukuba izincamathelisi zebhakethi zinokufuna ukutshintshwa emva kokuba ziphathwe malunga neetoni ezingama-400,000 zezinto, nto leyo ebonisa ithuba elibalulekileyo kwizityalo lokucwangcisa ulondolozo lokuthintela kunye nokunciphisa umngcipheko wokungasebenzi kakuhle okungacwangciswanga.
Iziqhagamshelo zekhonkco ezijikelezileyoZizinto ezicwangcisiweyo—ezivulekileyo kuyilo kodwa ezifunekayo ukuze zimelane nokungqubana okunzima, umthwalo oguquguqukayo, kunye neendawo ezirhabaxa ezifana neekhonkco ezivaliweyo ezizidibanisayo. Ngokusebenzisa ukubumba ngokuchanekileyo, ukukhetha izinto ezilungisiweyo, kunye nokuqina kwekhesi ekhethiweyo (i-carburizing) kwiindawo ze-interlink, abavelisi abaphambili abanjengo-RUD, CICSA, kunye no-Heko bavelisa izihlanganisi ezinikezela ukusebenza okuthembekileyo phantsi kweemfuno eziphezulu, eziqhubekayo ze-elevators zebhakethi zesityalo sesamente. Ukuhlolwa rhoqo kokuguguleka kwiindawo zoqhagamshelwano lwe-interlink, ukuqinisekiswa kokhuseleko lwe-fastener, kunye nokutshintshwa ngexesha elifanelekileyo ngokusekelwe kwi-tonnage ehanjiswayo zizinto ezibalulekileyo zokuthintela ukungaphumeleli okukhulu kunye nokwandisa ixesha lokusebenza kwenkqubo.
