Kunoma iyiphi injini yesimanje kukhona amayunithi afakwe, ashayelwa ibhande.Ngokusebenza okujwayelekile kwedrayivu, kwethulwa iyunithi eyengeziwe kuyo - i-tensioner belt belt.Funda konke mayelana nale yunithi, ukwakheka kwayo, izinhlobo nokusebenza, kanye nokukhetha okulungile nokushintshwa esihlokweni.
Yini i-drive belt tensioner?
I-Tension belt tensioner (i-tension roller noma i-drive belt tensioner) - iyunithi yesistimu yokushayela yamayunithi afakwe enjini yangaphakathi yomlilo;i-roller ene-spring noma enye indlela ehlinzeka ngezinga elidingekayo lokungezwani kwebhande lokushayela.
Izinga lokushayela kwamayunithi agibelekele - i-generator, iphampu yamanzi, iphampu yokuqondisa amandla (uma ikhona), i-compressor ye-air conditioner - incike kakhulu ekusebenzeni kweyunithi yamandla kanye nekhono lokusebenzisa yonke imoto.Isimo esidingekayo sokusebenza okujwayelekile kokushayela kwamayunithi afakiwe ukungezwani okulungile kwebhande elisetshenziswa kudrayivu - ngokungezwani okubuthakathaka, ibhande lizoshelela eduze kwama-pulleys, okuzodala ukuguga kwezingxenye kanye nokuncipha ukusebenza kahle kwamayunithi;Ukucindezeleka okwedlulele kwandisa izinga lokuguga kwezingxenye zokushayela futhi kubangele imithwalo engamukeleki.Kumamotho anamuhla, izinga elidingekayo lokungezwani kwebhande lokushayela linikezwa iyunithi elisizayo - i-tension roller noma i-tensioner nje.
I-tensioner yebhande lokushayela ibalulekile ekusebenzeni okuvamile kweyunithi yamandla, ngakho le ngxenye kufanele ishintshwe uma kwenzeka noma yikuphi ukungasebenzi kahle.Kodwa ngaphambi kokuthenga i-roller entsha, udinga ukuqonda izinhlobo zayo ezikhona, ukuklama kanye nesimiso sokusebenza.
Izinhlobo kanye nomklamo we-drive belt tensioners
Noma iyiphi i-tensioner yebhande lokushayela inezingxenye ezimbili: idivayisi eqinisayo eyenza amandla adingekayo, kanye nerola edlulisela la mandla ebhandeni.Kukhona futhi amadivaysi asebenzisa i-tensioner-damper - awanikezi kuphela ukungezwani kwebhande elidingekayo, kodwa futhi anciphisa ukuqina kokugqoka kwebhande nama-pulleys amayunithi ezindleleni zesikhashana zokusebenza kweyunithi yamandla.
I-tensioner ingaba ne-roller eyodwa noma amabili, lezi zingxenye zenziwe ngendlela yensimbi noma isondo lepulasitiki elinomsebenzi osebenzayo lapho ibhande ligoqa khona.I-roller ifakwe kudivayisi ye-tensioning noma kubakaki abakhethekile ngokusebenzisa i-rolling bear (ibhola noma i-roller, ngokuvamile umugqa owodwa, kodwa kukhona amadivaysi ane-double-row bearings).Njengomthetho, indawo yokusebenza ye-roller ibushelelezi, kodwa kunezinketho ezinamakholomu noma ama-protrusions akhethekile avimbela ibhande ukuthi lingasheleli ngenkathi injini isebenza.
Ama-roller afakwe ngqo kumadivayisi okuqinisa amandla noma ezingxenyeni ezimaphakathi ngendlela yabakaki bemiklamo ehlukahlukene.Imishini yokuqinisa ingahlukaniswa ngamaqembu amabili ngokuya ngendlela yokulungisa amandla okucindezela ebhande lokushayela:
● Ngokulungiswa ngesandla kwezinga lokushuba;
● Ngokulungiswa okuzenzakalelayo kwezinga lokushuba.
Iqembu lokuqala lihlanganisa izindlela ezilula ekwakhiweni, ezisebenzisa amadivaysi e-eccentric nama-slide acindezelayo.I-eccentric tensioner yenziwe ngendlela ye-roller ene-axis ye-offset, lapho ijikeleziswa lapho i-roller ilethwa eduze noma kude nebhande, okunikeza ushintsho kumandla okucindezela.I-tensioner yama-slide yenziwe ngendlela yerola efakwe kusilayidi esinyakazayo esikwazi ukuhamba emseleni wegayidi (ubakaki).Ukunyakaza kwe-roller eduze nomhlahlandlela kanye nokulungiswa kwayo endaweni ekhethiwe kwenziwa nge-screw, umhlahlandlela ngokwawo ufakwe i-perpendicular to the ibhande, ngakho-ke, lapho i-roller ihamba ngakho, amandla okucindezela ashintsha.
Amadivayisi anokulungiswa okubhaliwe kokungezwani kwebhande ezinjinini zanamuhla awavamile ukusetshenziswa, ngoba ane-drawback ephawulekayo - isidingo sokushintsha ukuphazamiseka ngesikhathi sokufakwa kokuqala kwale ngxenye futhi njengoba ibhande linwebeka.Ama-tensioners anjalo awakwazi ukuhlinzeka ngezinga elidingekayo lokungezwani kwebhande phakathi nayo yonke impilo yenkonzo, futhi ukulungiswa kwesandla akusindisi ngaso sonke isikhathi isimo - konke lokhu kuholela ekugqokeni okukhulu kwezingxenye zokushayela.
Ngakho-ke, izinjini zanamuhla zisebenzisa amadivaysi e-tensioning ngokulungiswa okuzenzakalelayo.Ama-tensioners anjalo ahlukaniswe ngamaqembu amathathu ngokuya ngomklamo nomgomo wokusebenza:
● Ngokusekelwe emithonjeni ye-torsion;
● Ngokusekelwe emithonjeni yokucindezela;
● Ngama-damper.
Amadivayisi asetshenziswa kakhulu asekelwe emithonjeni ye-torsion - ahlangene futhi enza imisebenzi yawo ngempumelelo.Isisekelo sedivayisi iyisiphethu esihlanganisiwe esinobubanzi obukhulu esibekwe enkomishini eyi-cylindrical.I-spring enekhoyili eyodwa eyeqisayo igxilile engilazini, futhi ikhoyili ephambene ihlezi kubakaki nge-roller, ingilazi kanye nobakaki kungaphendukiswa nge-engeli ethile ekhawulelwe yizitobhi.Ekwenziweni kwedivayisi, ingilazi kanye nabakaki kuzungeziswa nge-engeli ethile futhi kulungiswe kule ndawo ngedivayisi yokuphepha (hlola).Lapho ufaka i-tensioner enjinini, isheke liyasuswa futhi ubakaki uphambuka ngaphansi kwesenzo sentwasahlobo - ngenxa yalokho, i-roller iphumula ngokumelene nebhande, ihlinzeka ngezinga elidingekayo lokuphazanyiswa kwayo.Esikhathini esizayo, intwasahlobo izogcina ukungezwani okuhleliwe, okwenza ukulungiswa kungadingekile.
Amadivayisi asekelwe kuziphethu zokucindezela asetshenziswa kancane, njengoba athatha isikhala esiningi futhi awasebenzi kahle.Isisekelo sedivayisi ye-tensioning ibakaki ene-roller, enokuxhumana okujikelezayo ne-spring cylindrical spring.Ukuphela kwentwasahlobo kwesibili kufakwe injini - lokhu kuqinisekisa ukuphazamiseka kwebhande elidingekayo.Njengasesimeni sangaphambilini, amandla okucindezela entwasahlobo asethwe efektri, ngakho ngemva kokufaka idivayisi enjinini, isheke noma i-fuse yomklamo ohlukile iyasuswa.
Ukuthuthukiswa kwama-tensioners ngesiphethu sokucindezela kwakuyithuluzi elinama-dampers.I-tensioner inomklamo ofana nalokhu okuchazwe ngenhla, kodwa intwasahlobo ithathelwa indawo yi-damper, efakwe kubakaki nge-roller kanye ne-motor ngosizo lwama-eyelets.I-damper iqukethe i-compact hydraulic shock absorber kanye nesiphethu esihlanganisiwe, futhi i-shock absorber ingatholakala kokubili ngaphakathi kwentwasahlobo futhi isebenze njengesekelo lekhoyili yokugcina yentwasahlobo.I-damper yalo mklamo ihlinzeka ngokuphazamiseka kwebhande elidingekayo, kuyilapho ihambisa ukudlidliza kwebhande lapho iqala injini nasemamodi esikhashana.Ukuba khona kwe-damper kwandisa ngokuphindaphindiwe impilo yokushayela kwamayunithi afakwe futhi kuqinisekisa ukusebenza kwayo ngokuphumelelayo.
Sengiphetha, kufanele kuqashelwe ukuthi umklamo ochaziwe unama-tensioners ane-roller eyodwa nambili.Kulesi simo, amadivaysi anama-roller amabili angaba nedivayisi eyodwa evamile yokucindezela, noma ahlukanise amadivaysi e-roller ngayinye.Zikhona ezinye izixazululo ezakhayo, kodwa ziye zathola ukusatshalaliswa okuncane, ngakho ngeke sizicabangele lapha.
Izinkinga zokukhetha, ukushintshwa nokulungiswa kwe-tensioner yebhande lokushayela
I-tension roller yebhande lokushayela, njengebhande ngokwalo, inomthombo olinganiselwe, ukuthuthukiswa okufanele kushintshwe.Izinhlobo ezahlukene ze-tensioners zinezinsiza ezihlukile - ezinye zazo (i-eccentric elula kakhulu) kufanele zishintshwe njalo futhi kanye nokushintshwa kwebhande, futhi amadivaysi asekelwe emithonjeni kanye nama-dampers angasebenza cishe phakathi nesikhathi sonke sokusebenza kweyunithi yamandla.Isikhathi nenqubo yokushintsha amadivaysi okucindezela kuboniswa ngumkhiqizi weyunithi ethile yamandla - lezi zincomo kufanele zilandelwe ngokuqinile, ngaphandle kwalokho imiphumela emibi ehlukahlukene yeyunithi yamandla ingenzeka, kufaka phakathi ukugcwala kwayo (ngenxa yokushisa ngokweqile ngenxa yokumisa iphampu. ).
Yilezo zinhlobo kuphela namamodeli ama-tensioners anconywe umenzi weyunithi yamandla okufanele athathwe ukuze ashintshwe, ikakhulukazi izimoto ezingaphansi kwewaranti.Amadivayisi "okungewona awomdabu" angeke ahambisane nezici "zendabuko", ngakho-ke ukufakwa kwawo kuholela ekushintsheni kwamandla okucindezela kwebhande kanye nokuwohloka kwezimo zokusebenza zedrayivu yamayunithi afakiwe.Ngakho-ke, ukushintshwa okunjalo kufanele kusetshenziswe kuphela ezimweni ezimbi kakhulu.
Lapho uthenga idivayisi tensioning, kufanele uthenge zonke izingxenye ezidingekayo ngoba (uma zingafakiwe) - fasteners, abakaki, iziphethu, njll Kwezinye izimo, awukwazi ukuthatha tensioners lonke, kodwa ukulungisa kits - rollers kuphela efakiwe. ama-bearings, amabakaki, ama-dampers ahlanganiswe neziphethu, njll.
Ukushintshwa kwe-tensioner yebhande lokushayela kufanele kwenziwe ngokuhambisana nemiyalelo yokukhanda nokugcinwa kwemoto.Lo msebenzi ungenziwa kokubili ngebhande elifakiwe futhi ibhande lisusiwe - konke kuncike ekwakhiweni kwedrayivu kanye nendawo yedivayisi yokucindezela.Kungakhathaliseki ukuthi yikuphi, ukufakwa kwe-spring tensioners kuhlale kwenziwa ngendlela efanayo: idivayisi kanye nebhande kuqala ukufakwa endaweni yabo, bese isheke lisusiwe - lokhu kuholela ekukhululweni kwentwasahlobo kanye nokungezwani kwengcindezi. ibhande.Uma nganoma yisiphi isizathu ukufakwa kwe-tensioner enjalo kwenziwa ngokungalungile, kuyoba nzima ukuphinda uyifake.
Uma idivayisi yokucindezela ikhethwe kahle futhi ifakwe enjinini, idrayivu yamayunithi izosebenza ngokujwayelekile, iqinisekise ukusebenza ngokuzethemba kwayo yonke iyunithi yamandla.
