Umthengisi wezixhobo zokwakha izisombululo zoomatshini bokwakha kangangeminyaka engama-30.
Uninzi lweengxaki ze-mini excavator final drive zichongwa ngeempawu - ingxolo, ukuvuza, ubushushu, ukulahleka kwe-drive - ngaphandle kokufumanisa kuqala ukuba yeyiphi na kwicandelo ezimbini ezahlukeneyo zoomatshini ngaphakathi kweyunithi engasebenziyo. I-final drive kuyo nayiphi na imatshini ukusuka kwi-0.8 t ukuya kwi-6 t idibanisa i-hydraulic piston motor kunye ne-planetary reduction gearbox kwindawo enye. Zabelana nge-shaft kunye ne-case, kodwa iindlela zazo zokusilela, iintlobo zolwelo, kunye neziphumo zokulungisa zahlukile ngokupheleleyo. Ukuzidibanisa yimbangela eyintloko yokutshintshwa kweemoto ezingeyomfuneko kunye nokusilela kokwakhiwa kwakhona kwangaphambi kwexesha.
Ngaphambi kokuba uxilonge olunye, chonga ukuba loluphi uhlangothi loxinzelelo lokugqibela oluvelise uphawu. Eyona ndlela ithembekileyo ayifuni zixhobo: chonga ulwelo oluvuzayo okanye olungasebenziyo nge-viscosity.
Icala leMoto yeHydraulic
Ulwelo lubonakala lubhityile — lufana nolwelo lomatshini olukhanyayo okanye ulwelo lwebrake. Ukuvuza kuvela kwiindawo zokudityaniswa kwepayipi, kwindawo yokutywina umatshini, okanye ecaleni kwendawo yokutywina umbane. Iimpazamo apha: ukusilela kwetywina lombane, ukuguguleka kwepleyiti yeport, ukuguguleka kwebhareli/isiliphu, ukuguguleka kwepompo yokutshaja. Uphawu: ukulahleka kwamandla okujikeleza, ukuhamba kwamanzi aphezulu, ubushushu obugqithisileyo.
Icala leGearbox yePlaneti
Ulwelo luqinile kwaye luqinile — ioyile yegiya. Ukuvuza kuvela ebusweni bokufakelwa kwe-sprocket (ukusilela kwe-duo-cone seal) okanye kwipleyiti yesiciko segiya. Iimpazamo apha: i-floating face seal engasebenzi kakuhle, ii-planet gears ezigugileyo okanye ii-carrier bearings, ukwakheka koxinzelelo lwegiya ngenxa yokuvuza kwe-motor shaft seal. Uphawu: ioyile kwiitrekhi, ukugaywa phantsi komthwalo, i-locked drive.
Olu mahluko lubalulekile ngaphambi kokuvula nantoni na. Imoto entsha efakwe kwibhokisi yegiya engcolileyo - okanye i-gearbox eyakhiwe ngokutsha ngaphandle kokulungisa isitywina se-motor shaft esibangele ukungena koxinzelelo - iya kuphinda ingasebenzi kwiiyure emva kokuba ibuyele kwinkonzo.
Xa isitywino sangaphakathi se-motors sonakala, ulwelo lwe-hydraulic olunoxinzelelo oluphezulu luphuma igazi ludlule kwisitywino luze lungene kwigumbi lebhokisi yegiya yeplanethi. Ibhokisi yegiya ayinandlela yokunciphisa uxinzelelo. Njengoko ulwelo lwe-hydraulic luqokelelana, lususa ioyile yegiya kwaye lucinezele umngxuma. Uphawu lokuqala olubonakalayo yipleyiti yesigqubuthelo sebhokisi yegiya eqala ukulila okanye ukudumba - ukuvuza okuncinci, okuzinzileyo kweoyile yegiya phantsi koxinzelelo oluncinci oluvela kwisigqubuthelo esingaguqukiyo.
Ukuba oku akulungiswa, ipleyiti yokugquma iyahlukana phantsi koxinzelelo lokusebenza. Iseti yegiya, iibheringi zeplaneti, kunye negiya yeringi emva koko zichatshazelwa kuxinzelelo lwe-hydraulic ngqo, ungcoliseko olurhabaxa, kunye nokulahlekelwa kukuthambisa ngaxeshanye. Isiphumo sihlala sitshatyalaliswa ngokupheleleyo kwecandelo leplanethi ngaphakathi kweshifti enye yokusebenza.
Isalathisi sentsimi: Ukuba isigqubuthelo sebhokisi yegiya sivuza ioyile yegiya kodwa imotor ngokwayo ayibonisi kuvuza kwangaphandle kwi-hose fittings okanye kwi-case drain, isitywino se-motor shaft singumthombo wempazamo - hayi i-cover gasket. Buyisela isitywino se-motor shaft uze uhlambe ioyile yebhokisi yegiya ngaphambi kokuba uphinde uyihlanganise. Ukufaka i-cover gasket entsha kukodwa akuyi kuyisombulula le nto.
Ukungaphumeleli kokuhamba okungalinganiyo — enye indlela isebenza buthathaka okanye ingashukumi ngelixa enye isebenza ngokwesiqhelo — yeyona ndlela ixhaphakileyo yokusilela kwemoto yokuhamba ye-mini excavator. Kwakhona yeyona ndlela ixhaphakileyo yokufumanisa ingxaki. Iimpazamo ezimbini eziphezulu zivelisa iimpawu ezifanayo ngelixa ishiya idrayivu yokugqibela ingonakali kwaphela.
Ijoyinti ejikelezayo idlula unikezelo lwe-hydraulic kwaye ibuyele kuzo zombini iimoto zokuhamba ngomzimba ojikelezayo onezibuko ezininzi. Iiringi zokuvala zangaphakathi zahlula imijelo yokuhamba. Xa iringi enye inxiba okanye ifumana umngxuma kwimbobo yomzimba, ukuhamba kwemoto enye kuphuma igazi liye kwizibuko elikufutshane okanye kumgca wokubuyela ngaphambi kokuba ifike kwi-drive yokugqibela. Imoto echaphazelekayo ifumana uxinzelelo oluphantsi kunye nokuhamba; umqhubi ubona oku njengokusilela kwemoto. Faka i-pressure gauge kwizibuko lokungena kwemoto. Ukuba uxinzelelo lonikezelo kwimoto lungaphantsi kwe-30-40 bar ngaphantsi koxinzelelo lwesekethe ephambili ngexesha lovavanyo lwe-travel stall, ijoyinti ejikelezayo yimpazamo, hayi imoto.
Iimoto zokuhamba ezikwiimashini ezingaphezulu kwe-1.5 t zisebenzisa ibhreki yokupaka ekhutshwa yi-hydraulic efakwe kwintwasahlobo edityaniswe kwisivalo sesiphelo semoto. Ukuba i-port yokukhulula ibhreki ithintelwe — ngumgca womqhubi ovaliweyo, i-O-ring engaphumeleliyo kwivalvu yokukhulula, okanye isignali yomqhubi obuthathaka — ibhreki ayiphumi ngokupheleleyo. Imoto izama ukujikeleza ngokuchasene nokubandakanyeka kwebhreki engaphelelanga. Isiphumo: umzila ocothayo, ovelisa ubushushu kwindawo yemoto obungalinganiyo nomthwalo womsebenzi, kwaye onokubopha ngesantya esiphantsi ngelixa usebenza ngokukhululekileyo ngesantya esiphezulu njengoko uxinzelelo lwe-hydraulic luyoyisa amandla okuqhobosha angaphelelanga.
Ukusula i-drive housing yokugqibela kunye nokusebenzisa umatshini imizuzu eli-10 phantsi komthwalo — uze ujonge ngetotshi ngaphambi kokuba i-oyile isasazwe kwakhona — kuchonga indawo yokuqala yokuvuza ngaphandle kokususa. Iindawo ezintathu zibangela uninzi lwamatyala kudidi lwe-0.8 t–6 t:
Ukuvuza kobuso be-sprocket yioyile yegiya evela kwisitywina se-duo-cone esingasebenziyo (esidadayo). Isitywina sineendandatho ezimbini zesinyithi ezidityanisiweyo ezicinezelweyo ngezakhi zerabha ze-toroidal. Ukungaphumeleli kwesitywina kudla ngokubangelwa kukungcola okungena phakathi kobuso bokunamathela, ngokuqina kwento yerabha kwiimashini ezigcinwe ngaphandle kokusebenza rhoqo, okanye ngumzila ongalungelelananga ovelisa umthwalo we-axial kubuso besitywina. Ukutshintshwa kufuna izixhobo zokutsala isitywina kunye nomphezulu ococekileyo, othe tyaba wokudibana - ukufakwa ngaphandle kokuqinisekisa ukuba ubuso bebhore yendlu buthe tyaba kubangela malunga ne-30% yokungaphumeleli kwangaphambi kwexesha.
Ukuvuza kwepleyiti yokugquma phantsi koxinzelelo olukhaphukhaphu kubonisa ukuba i-gasket ye-O-ring ayisebenzi kakuhle (eqheleke kwiikhava ze-bolt-on emva kokujikeleza kobushushu) okanye ukwakheka koxinzelelo lwebhokisi yegiya ngenxa yempazamo yesitywina se-motor shaft echazwe apha ngasentla. Ezi zizathu zimbini zifuna ukungenelela okwahlukileyo ngokupheleleyo.
Isithuba sokukhupha amanzi okanye ukuvuza kwepayipi yi-hydraulic fluid, ayilo-oyile yegiya. Oku phantse kuhlala kukusilela kwe-fitting okanye i-hose clamp endaweni yempazamo yangaphakathi yemoto - kodwa ukuba uxinzelelo lwe-case drain luphakanyisiwe, lunokubonisa isihluzo se-case drain esivaliweyo kumgca wokubuyela, oya kuthi ekugqibeleni ucinezele i-seal ye-motor shaft ukuba ingasebenzi.
