Kuyo nayiphi na injini yanamhlanje kukho iiyunithi eziphakanyisiweyo, eziqhutywa ngebhanti.Ukusebenza ngokuqhelekileyo kwe-drive, iyunithi eyongezelelweyo ifakwe kuyo - i-belt belt tensioner.Funda konke malunga nale yunithi, uyilo lwayo, iintlobo kunye nokusebenza, kunye nokukhetha okulungileyo kunye nokutshintshwa kwinqaku.
Yintoni ibhanti lokuqhuba?
I-Tension belt tensioner (i-tension roller okanye i-drive belt tensioner) - iyunithi yenkqubo yokuqhuba iiyunithi ezifakwe kwi-injini yokutsha yangaphakathi;i-roller enentwasahlobo okanye enye indlela ebonelela ngeqondo elifunekayo loxinzelelo lwebhanti yokuqhuba.
Umgangatho wokuqhutywa kweeyunithi eziphakanyisiweyo - i-generator, ipompo yamanzi, ipompo yokulawula amandla (ukuba ikhona), i-compressor ye-air conditioner - ubukhulu becala ixhomekeke ekusebenzeni kweyunithi yamandla kunye nokukwazi ukusebenzisa isithuthi sonke.Imeko efunekayo yokusebenza okuqhelekileyo kokuqhutywa kweeyunithi eziphakanyisiweyo kukunyanzeliswa okuchanekileyo kwebhanti esetyenziswe kwi-drive - kunye noxinzelelo olubuthathaka, ibhanti liya kutyibilika kunye neepulleys, eziya kubangela ukunyuka kwamacandelo kunye nokuncipha kwi-pulleys. ukusebenza kakuhle kweeyunithi;Uxinzelelo olugqithisileyo lukwanyusa izinga lokunxiba lamacandelo okuqhuba kwaye kubangele imithwalo engamkelekanga.Kwiimoto zanamhlanje, iqondo elifunekayo lokunyanzeliswa kwebhanti yokuqhuba linikezelwa yiyunithi encedisayo - i-tension roller okanye i-tensioner nje.
I-tensioner yebhanti yokuqhuba ibalulekile ekusebenzeni okuqhelekileyo kweyunithi yamandla, ngoko ke le nxalenye kufuneka itshintshwe xa kukho nakuphi na ukungasebenzi.Kodwa ngaphambi kokuthenga i-roller entsha, kufuneka uqonde iintlobo zayo ezikhoyo, ukuyila kunye nomgaqo wokusebenza.
Iintlobo kunye noyilo lwee-tensioners zebhanti zokuqhuba
Nayiphi na i-tensioner yebhanti ye-drive iqulethwe ngamacandelo amabini: i-tensioning device eyenza amandla afunekayo, kunye ne-roller ehambisa eli gunya kwibhanti.Kukho nezixhobo ezisebenzisa i-tensioner-damper - aziboneleli kuphela ukunyanzeliswa kwebhanti efunekayo, kodwa zinciphisa ukugqithiswa kwebhanti kunye neepulleys zeeyunithi kwiindlela ezidlulayo zokusebenza kweyunithi yamandla.
I-tensioner ingaba ne-roller enye okanye ezimbini, ezi nxalenye zenziwe ngendlela yentsimbi okanye ivili leplastiki kunye nomsebenzi ogudileyo apho ibhanti lihamba khona.I-roller ifakwe kwi-tensioning device okanye kwi-bracket ekhethekileyo ngokusebenzisa i-rolling bearing (ibhola okanye i-roller, ngokuqhelekileyo i-single-row, kodwa kukho izixhobo ezine-double-row bearings).Njengomthetho, indawo yokusebenza ye-roller igudileyo, kodwa kukho iinketho ngeekholeji okanye iiprotrusions ezikhethekileyo ezithintela ibhanti ukuba iqhube ngelixa injini isebenza.
Iirola zifakwe ngokuthe ngqo kwizixhobo zoxinzelelo okanye kwiindawo eziphakathi ngendlela yezibiyeli zoyilo olwahlukeneyo.Izixhobo zoxinzelelo zinokwahlulwa zibe ngamaqela amabini ngokwendlela yokulungelelanisa amandla oxinzelelo lwebhanti yokuqhuba:
● Ngohlengahlengiso lwezandla lweqondo loxinzelelo;
● Ngohlengahlengiso oluzenzekelayo lweqondo loxinzelelo.
Iqela lokuqala libandakanya ezona zixhobo zilula kuyilo, ezisebenzisa izixhobo ze-eccentric kunye nezilayidi.I-eccentric tensioner yenziwe ngendlela ye-roller ene-axis ye-offset, xa ijikelezwa ngeenxa zonke apho i-roller iziswe ngokusondeleyo okanye kude nebhanti, enika utshintsho kumandla oxinzelelo.I-tensioner yesilayidi yenziwe ngendlela ye-roller efakwe kwi-slider ehambayo enokuthi ihambe kunye ne-groove yesikhokelo (i-bracket).Ukuhamba kwe-roller kunye nesikhokelo kunye nokulungiswa kwayo kwindawo ekhethiweyo kuqhutyelwa nge-screw, isikhokelo ngokwawo sifakwe kwi-perpendicular kwibhanti, ngoko ke, xa i-roller ihamba nayo, amandla oxinzelelo atshintsha.
Izixhobo ezinokulungiswa kwesandla soxinzelelo lwebhanti kwiinjini zanamhlanje azifane zisetyenziswe, ekubeni zine-drawback ephawulekayo - imfuneko yokutshintsha ukuphazamiseka ngexesha lofakelo lokuqala lwale nxalenye kwaye njengoko ibhanti isolula.Abaxhaphazi abanjalo abanako ukubonelela ngeqondo elifunekayo loxinzelelo lwebhanti ngexesha lonke lobomi benkonzo, kwaye uhlengahlengiso lwezandla alusoloko lusindisa imeko - konke oku kukhokelela ekunxibeni okunzulu kwamacandelo okuqhuba.
Ke ngoko, iimotor zanamhlanje zisebenzisa izixhobo zoxinzelelo kunye nohlengahlengiso oluzenzekelayo.Ezi tensioners zahlulwe zibe ngamaqela amathathu ngokoyilo kunye nomgaqo wokusebenza:
● Ngokusekwe kwimithombo yokujijeka;
● Ngokusekelwe kwimithombo yoxinzelelo;
● Ngezidambisi manzi.
Ezona zixhobo zisetyenziswa kakhulu zisekelwe kwimithombo ye-torsion - zihlangene kwaye zenza imisebenzi yazo ngokufanelekileyo.Isiseko sesixhobo yintwasahlobo ephothiweyo enobubanzi obukhulu ebekwe kwikomityi ye-cylindrical.Intwasahlobo ene-coil enye egqithisileyo igxininiswe kwiglasi, kwaye i-coil echaseneyo ixhomekeke kwi-bracket kunye ne-roller, i-glass kunye ne-bracket inokujikelezwa kwi-angle ethile elinganiselwe ngokuyeka.Ukwenziwa kwesixhobo, iglasi kunye ne-bracket zijikelezwa kwi-angle ethile kwaye zilungiswe kule ndawo ngesixhobo sokhuseleko (khangela).Xa ufaka i-tensioner kwi-injini, isheke iyasuswa kwaye i-bracket igxininiswe phantsi kwesenzo sentwasahlobo - ngenxa yoko, i-roller ixhomekeke kwibhanti, inika iqondo elifunekayo lokuphazamiseka kwayo.Kwixesha elizayo, intwasahlobo iya kugcina uxinzelelo olumiselweyo, ukwenza uhlengahlengiso olungadingekile.
Izixhobo ezisekelwe kwimithombo yoxinzelelo zisetyenziswa rhoqo, njengoko zithatha indawo eninzi kwaye zingasebenzi kakuhle.Isiseko sesixhobo se-tensioning yi-bracket ene-roller, ene-swivel connection kunye ne-spring cylindrical spring.Ukuphela kwesibini kwentwasahlobo kufakwe kwi-injini - oku kuqinisekisa ukuphazamiseka okufunekayo kwebhanti.Njengoko kwimeko yangaphambili, amandla oxinzelelo entwasahlobo abekwe kwifektri, ngoko emva kokufaka isixhobo kwi-injini, isheke okanye i-fuse yoyilo olwahlukileyo luyasuswa.
Ukuphuhliswa kwee-tensioners kunye ne-spring compression spring yayiyisixhobo esinama-dampers.I-tensioner ine-design efana nale ichazwe ngasentla, kodwa intwasahlobo ithathelwa indawo yi-damper, efakwe kwi-bracket kunye ne-roller kunye ne-motor ngoncedo lwee-eyelets.I-damper iqukethe i-compact hydraulic shock absorber kunye ne-spring edibeneyo, kwaye i-shock absorber inokufumaneka zombini ngaphakathi kwentwasahlobo kwaye isebenze njengenkxaso yekhoyili yokugqibela yentwasahlobo.I-damper yolu yilo ibonelela ngokuphazamiseka okufunekayo kwebhanti, ngelixa ilula ukungcangcazela kwebhanti xa uqala injini kunye neendlela ezidlulayo.Ubukho be-damper ngokuphindaphindiweyo kwandisa ubomi bokuqhuba kweeyunithi eziphakanyisiweyo kunye nokuqinisekisa ukusebenza kwayo ngokufanelekileyo.
Ukuqukumbela, kufuneka kuqatshelwe ukuba uyilo oluchaziweyo lune-tensioners zombini kunye ne-roller ezimbini.Kule meko, izixhobo ezinee-roller ezimbini zinokuba nesixhobo esisodwa esiqhelekileyo soxinzelelo, okanye izixhobo ezihlukeneyo zoluhlu ngalunye.Kukho ezinye izisombululo ezakhayo, kodwa zifumene usasazo oluncinane, ngoko asiyi kuziqwalasela apha.
Imiba yokukhetha, ukutshintshwa kunye nohlengahlengiso lwe-tensioner yebhanti yokuqhuba
I-roller ye-tension yebhanti yokuqhuba, njengebhanti ngokwayo, inomthombo olinganiselweyo, ukuphuhliswa kwayo kufuneka kuthathelwe indawo.Iindidi ezahlukeneyo ze-tensioners zinezibonelelo ezahlukeneyo - ezinye zazo (ezona zilula kakhulu) kufuneka zitshintshwe rhoqo kwaye kunye nokutshintshwa kwebhanti, kunye nezixhobo ezisekelwe kwimithombo kunye ne-dampers zinokusebenza phantse ngexesha lokusebenza kweyunithi yamandla.Ixesha kunye nenkqubo yokutshintsha izixhobo zoxinzelelo ziboniswa ngumvelisi weyunithi ethile yamandla - ezi ngcebiso kufuneka zithotyelwe ngokungqongqo, kungenjalo iziphumo ezibi ezahlukeneyo zeyunithi yamandla zinokwenzeka, kubandakanywa ukuxinana kwayo (ngenxa yokutshisa ngenxa yokumisa impompo. ).
Kuphela ezo ntlobo kunye neemodeli ze-tensioners ezicetyiswa ngumenzi weyunithi yamandla kufuneka zithathelwe ukutshintshwa, ngakumbi kwiimoto eziphantsi kwewaranti.Izixhobo "ezingezona zomthonyama" azikwazi ukuhambelana neempawu "zemveli", ngoko ke ukufakela kwazo kukhokelela ekutshintsheni kwamandla oxinzelelo lwebhanti kunye nokuwohloka kweemeko zokusebenza zokuqhutywa kweeyunithi eziphakanyisiweyo.Ngoko ke, ukutshintshwa okunjalo kufuneka kusetyenziswe kuphela kwiimeko ezinzima.
Xa uthenga isixhobo soxinzelelo, kufuneka uthenge zonke izinto eziyimfuneko kulo (ukuba azibandakanyi) - izibophelelo, izibiyeli, imithombo, njl.njl Kwezinye iimeko, awukwazi ukuthatha i-tensioners yonke, kodwa izixhobo zokulungisa - ii-roller kuphela ezifakelweyo. iibheringi, izibiyeli, iidampers ezidityaniswe nemithombo, njl.
Ukutshintshwa kwe-tensioner yebhanti yokuqhuba kufuneka kuqhutywe ngokuhambelana nemiyalelo yokulungiswa nokugcinwa kwesithuthi.Lo msebenzi unokwenziwa zombini kunye nebhanti efakwe kunye nebhanti isusiwe - konke kuxhomekeke kuyilo lokuqhuba kunye nendawo yesixhobo soxinzelelo.Kungakhathaliseki oku, ukufakwa kwe-spring tensioners kuhlala kuqhutyelwa ngendlela efanayo: isixhobo kunye nebhanti zifakwe kuqala kwindawo yazo, kwaye emva koko isheke iyasuswa - oku kukhokelela ekukhululweni kwentwasahlobo kunye nokuxinana kwe ibhanti.Ukuba ngenxa yaso nasiphi na isizathu ukufakwa kwe-tensioner enjalo kwenziwa ngokungalunganga, ngoko kuya kuba nzima ukuyifaka kwakhona.
Ukuba isixhobo soxinzelelo sikhethwe ngokuchanekileyo kwaye sifakwe kwi-injini, ukuqhutywa kweeyunithi kuya kusebenza ngokuqhelekileyo, ukuqinisekisa ukusebenza ngokuzithemba kwayo yonke iyunithi yamandla.
