Iziketanga zamaketanga ezithuthuthu: izivivinyo zokuqhathanisa, ukugcinwa kanye nethiyori

Amakhithi amaketango alula, ama-O-ring noma aphansi ayatholakala namuhla ngezimfanelo ezihlukahlukene, ukusebenza kwawo nokuqina kwawo kuzoncika endleleni obanakekela ngayo. Konke odinga ukukwazi ngesihloko ku-moto esiteshini.

Iketango kanye nebhande lamazinyo le-analogue livumela amagiya amabili ukuthi axhumeke aqhelelene kakhulu ukuze akwazi ukushayela ngqo. Ngakho-ke, iketango lidlulisa amandla aqinile ekugcineni kwawo okunwetshiwe ukusuka egiyeni eliqhutshwayo lokudlulisela kugiya lokushayela, eliqhelelene cishe ngamasentimitha angama-60. Liphindaphindwa ngobubanzi obukhulu begiya lendandatho, la mandla azodala "i-torque" eyengeziwe (noma torque) kunegiya elinendawo encane. Kodwa-ke, leli xabiso le-torque lesondo lomqhele liyafana nesondo elingemuva, ngoba lenziwe ngocezu olulodwa futhi line-eksisi efanayo yokujikeleza. Ngakho, i-torque ebalulekile esondweni lokushayela (emuva) kanye nesisindo esincane sezithuthuthu sichaza isikhathi sabo "se-canonical", ngisho nasendaweni yesi-6! Yiqiniso, i-torque yesi-5, yesi-4 noma ngaphansi, i-torque yegiya izohlale iphakeme, ngakho-ke i-torque emqhele futhi ngakho-ke isondo elingemuva izokwanda ngesilinganiso esifanayo. Ingabe uzolandela?

Izinhlobo ezahlukene zamaketanga

Iketango elilula iyona endala futhi ngokuqinisekile edume kakhulu. Ngenxa yokunakekelwa okunzima kakhulu (ngakho-ke ukuguga okusheshayo) nokusebenza okuphezulu kwezinjini zesimanje, sekunesikhathi eside wanyamalala ezithuthuthwini eziningi. Nokho, ngenxa yezizathu zezomnotho, 50 cm3 futhi mayelana 125 cm3 kwasala. Kodwa-ke, iketango elilula ligcina inzuzo enkulu: akukho ukungqubuzana emalungeni, njengoba kungekho ukungqubuzana, ngakho-ke akukho ukulahlekelwa! Izindleko ezinqwabelene ziphumelela kakhulu kuneketango le-o-ring, ngakho lisasetshenziswa kabanzi emqhudelwaneni...lapho ukusebenza kubalulekile futhi ukuqina kungokwesibili.

Indandatho yocingo kuvele ngokunembile ukuxazulula inkinga yokugcotshwa kwama-axles ama-roller. Ngempela, ngesikhathi sokusebenza, igrisi isuswa ngokushesha kule ndawo yamasu futhi kunzima ukuyishintsha, okuholela ekugqokeni okusheshayo emhlanganweni. Ukuze kulungiswe lokhu, abakhiqizi babe nombono wokufaka i-o-ring ebizwa ngokuthi "O'ring" (ngenxa yesigaba esiphambene kokuthi O) phakathi kwalawa maphini namapuleti awo aseceleni. Evalelwe, evikelwe emanzini, esihlabathini nakwezinye izinto, amafutha okuqala ahlala endaweni isikhathi eside, ngaleyo ndlela anakekele ama-axles futhi ngenxa yalokho anikeze impilo yesevisi eyengeziwe!

Kodwa-ke, lolu chungechunge lwe-O-ring alunayo isondlo: okokuqala khumbula ukulihlanza njalo bese ugcoba amarola angaphandle ngegiya legiya le-SAE 80/90 EP, njalo emazinyweni. Ngaphandle uma ukhetha okokuthambisa okuwuchungechunge njengeScottoiler, Cameleon Oiler noma okunye okuzoyigcoba isikhathi eside.

Uma iketango lingcole kakhulu, ungalixubha usebenzisa udizili, uphethiloli wasendlini, noma ngisho nophethiloli okhishwa iphunga elibi (bona, phakathi kwezinye izinto, okokufundisa okuhle kakhulu kwe-morphing kuforamu ye-ms). Isexwayiso: Ungalokothi usebenzise uphethiloli noma, ngaphezu kwalokho, i-trichlorethylene, njengoba lokhu kungalimaza ama-axle seals! Futhi qaphela ukuvikela isondo elingemuva kunoma iyiphi i-protrusions ngokulimboza ngendwangu.

Ngokunakekelwa okuhle, impilo yesevisi ye-o-ring chain iphindwe kabili ngokwesilinganiso uma iqhathaniswa neketango elilula, ngezinye izikhathi lidlula i-50 km. Olunye uhlangothi lohlamvu lwemali ukuthi kunokungqubuzana okuningi, ikakhulukazi uma kusha ngaphambi kokugijima! Ukuze uqiniseke ngalokhu, kwanele ukuqhathanisa amandla okugoba ezintambo ezinikezwa yi-AFAM, isibonelo, ngesikhathi semibukiso yezithuthuthu noma, okungcono nakakhulu, ukushayela isithuthuthu ngaphambi nangemva kokufaka iketanga ngaphandle kwe-O-rings ... , uma inyakaza, iketango kufanele ligobe ukuze lihlangane ngokuhambisana negiya nomqhele. Phakathi nalokhu kujikeleza, izimpawu zigubha phakathi kwamapuleti angaphakathi nangaphandle, zinciphisa ukunyakaza, ngaleyo ndlela "zidle" amandla, noma kunalokho, namuhla, ukwandisa ukusetshenziswa kukaphethiloli!

Kungenxa yalesi sizathu ukuthi low friction chain, eliziqhenya ngokuhlanganisa okuhamba phambili kwayo yomibili imihlaba: ukungqubuzana okuncane (okungakho ukuncipha kwamandla amancane) nokuqina okuhle. Kodwa kanjani-ke? Imfihlo ilele ekuma kwe-gasket - ukusuka ku-O'Ring kuye ku-X'Ring noma ukuzungeza ukuze uwele - kanye nokukhethwa kwezinto noma i-nitrile ye-gasket ye-X'Ring. Ngamafuphi, nansi umkhiqizo osephepheni unazo zonke izimfanelo noma kunjalo. Kusazobonakala, ukukala ebhentshini...

Iketanga, amafutha, amafutha kanye nokugqokwa

Iseluleko sikaSanson, esivela kunkundla ye-ms

Ukugcoba ngamafutha abushelelezi: akuwona amafutha.

Amafutha awuketshezi: ageleza ngokushesha noma kancane, kodwa ayenzeka.

Lokhu kuyindaba kawoyela wegiya "SAE 80/90 EP".

Eqinisweni, ngokusho kwamagama, kungamafutha e-axles yemoto (EP = Extreme Pressure).

Amafutha egiya avame ukuba mncane.

Amafutha yimikhiqizo emi-2; insipho namafutha. Umsebenzi wensipho ukumunca uwoyela njengesipontshi. Ngokuya ngengcindezi kanye ne-capillarity, insipho izokhafula amafutha.

Insipho ngokwamakhemikhali iwumkhiqizo wokusabela kwe-asidi enezinto ezinamafutha, okungukuthi insipho yensimbi, umphumela wokusabela kwe-fatty acid (stearic, oleic) nge-hydroxide yensimbi (i-calcium, i-lithium, i-sodium, i-aluminium, i-magnesium) noma into yokuthambisa. Sikhuluma ngezinsipho ze-lithium, isibonelo, usawoti we-lithium njengama-lubricant aqinile. (Igrisi ewuketshezi enombala ophuzi ilungele isivinini esikhulu (samafutha) nokucindezela okuphansi.)

Ngakho-ke, inkulumo ethi: "nge-lubricant yohlobo lwe-gearbox ye-SAE 80/90 EP" ayifaneleki: kulokhu umuntu kufanele athi "amafutha", noma kunalokho "gcoba".

I-PS: Amafutha awafaneleki ukuthambisa amaketanga: azosebenza njenge-solvent, anciphise i-lubricant. Ngenxa yalokho, amafutha azosuswa lapho kufanele abe khona (azungeze i-axis yesixhumanisi). Ngisho noma kukhona ama-o-rings noma ama-X-rings, uphawu lukude nokuphelela. Ukubekezela okudingekayo ku-O-ring yi-1/100 mm, okude kakhulu nokunemba kweketango.

Igrisi esekelwe ku-solvent kuphela ene-capillarity enamandla kakhulu ezoyivumela ukuthi ingene e-O-ring naphezu kwe-O-ring futhi ibambe i-shaft yesixhumanisi. Lapho i-solvent ihwamuka (ngokusabalalisa), amafutha ahlala futhi i-solvent ithwala amafutha.

Amazinyo egiya namarola akufanele agcotshwe. Akukho ukuguga kukho kokubili (ngezikhathi ezijwayelekile). Ngempela, okuthiwa ama-roller atholakala eduze kwezimbazo zezixhumanisi.

Ngaphezu kwalokho, igama eliqondile leketanga lezithuthuthu zethu "i-roller chain" (ingxenye engaphandle, evame ukucwebezela ngemva kwemvula, egingqika phezu kwamazinyo amagiya). Ngakho-ke, ama-roller awagugi uma eginqika kahle.

I-chain wear inemithombo emibili:

- eyokuqala ukugqokwa kwe-axis kanye nengxenye ye-cylindrical engenalutho yesixhumanisi. Njengoba iketango lizungeza, kuba nokungqubuzana phakathi kwalezi zingxenye ezimbili. Ngokujwayelekile akufanele kube khona ukuxhumana kwensimbi/kwensimbi kuleli zinga. Amafutha, ngenxa yokungaguquguquki kwawo kanye nezimpawu zokucindezela okukhulu, kufanele asebenze njengesixhumi esibonakalayo ukuze izindawo "zishelele" phezu kwamafutha.

Ngaphansi kwethonya lokucindezela okukhulu (ukushuba kwenjini ku-chain kulinganiswa ngamathani!) I-Lubricant ingageleza futhi amanzi angakwazi ukungena, ukuze ukuthintana kwenzeke ngokuqondile kusuka ensimbi kuya ensimbi. Bese kuba negebe lensimbi, esimweni esibi kakhulu, i-weld. Leli iphuzu eliqinile elaziwayo, ku-piston/cylinder lokhu kungaba ukufutha.

Lapho nje umuntu engena kulezi zindawo, lapho ukugcoba kungaphelele, i-geometry yezixhumanisi iyashintsha: iketango liyakhula ngenxa yemidlalo ekhulayo (yokugqoka). Iphimbo le-chain liyashintsha, ngakho-ke ukujikajika akusakwenziwa kahle egiyeni nasemqhele. Eketheni eligugile, kubonakala ngokucacile ukuthi ukuxhumana kweketango emazinyweni kusondele, iketanga elidlule izixhumanisi zokuqala liphumile. Amandla adlula kuphela izixhumanisi ezimbalwa, ezingaphansi kwengcindezi eyengeziwe futhi iketango liyandiswa nakakhulu.

- kancane kancane, futhi lokhu kuyimbangela yesibili yokuguga, ama-rollers awasagingqiki phezu kwamazinyo, kodwa awadabule, okuholela ekugugeni kwamazinyo omumo owaziyo: "ikamu leqhude" egiyeni lokukhiphayo gearbox. futhi "wabona amazinyo" emqhele.

Masithole indlela yokuhlala sinezimbazo ezigcwele amafutha, isixhumi esibonakalayo esifanele (kokubili okubandayo nokushisayo), futhi sinamaketango angagugi (noma angagugi kancane)!

Qaphela: Amaketanga esikhathi ekesini elivalekile nasebhavuni likawoyela anomsindo, kodwa awacekeleki neze.

Iqhubeka nombiko wethu wochungechunge lwezithuthuthu ...

[-hlukanisa: ukuqhathanisa-]

Ukuqhathaniswa kwamaketanga ezithuthuthu

Iqiniso Mayelana ne-O'ring kanye ne-X'ring Low Friction Ring Chains

Kunzima ukwenza isiphetho mayelana nokusebenza kahle kweketango ngaphandle kokuba nesilinganiso esisodwa sokuqhathanisa ebhentshini. Ukwenza lokhu, siqhathanise ikhithi ye-O-ring chain yakudala ye-Enuma (O'Ring) nenye imodeli ye-low-friction (X'Ring) evela ku-Prokit. Isithuthuthu se-Guinea Pig yi-Kawasaki ZX-6R, eyayibanjelwe e-Fuchs BEI 261 booth e-Alliance 2 Roues (Montpellier).

Kulolu vivinyo lokuqala, ibhayisikili lifakwe isethi ye-chain yasekuqaleni, okungukuthi imodeli enezindandatho zakudala ezifana ne-Enuma EK MVXL 525 enezixhumanisi ezingu-108 kanye ne-28 km, egcinwa isesimweni esihle futhi isesimeni esihle. Izilinganiso zebhentshi zibushelelezi:

I-ZX-6R Isilinganiso Ngochungechunge Lwendandatho: 109,9 HP ku-12 rpm kanye ne-torque engu-629 μg ku-6,8 rpm

Ilandela uchungechunge olujwayelekile lwe-O'Ring, ukungqubuzana okuphansi kwe-X'Ring kwembula izimfihlo zayo ...

Kusele ukuqaqa isethi yeketango elidala futhi esikhundleni salo kufakwe umhlangano we-Prokit EK + JT nge-525 UVX (obomvu!) Iketango eliphansi le-friction lokulinganisa okusha ebhentshini. Izimo zezulu ezicishe zifane kufanele zinikeze ukunemba kokulinganisa okufanayo. Ububi, njenganoma iyiphi ingxenye yemishini, ukuthi iketango lidinga ukugijima okungaba ngu-1 km. Lokhu kuhlolwa kokuqala kwenziwa kuphela ngemuva kwe-000 km, lapho iketango lisadinga ukuba "liqine" ngokwanele.

Noma kunjalo I-Ninjette ikhiqiza amandla angu-112. @ 12 rpm netorque engu-482 μg @ 6,9 rpm noma 10 hp futhi omunye 239 mcg! Ukusebenza okumangalisayo osekuvele kuvelele ngokungangabazeki kungabangelwa ama-X'Ring Quadra low loss seals adumile asuka kulungelo lobunikazi le-EK. Ngakho-ke, ukwanda kwe-30-50% kwe-chain friction nge-O-rings evamile kubonakala kuqinisekisiwe. Kusele ukuthi iphinde ihlole ngemuva kwe-1 km.

Ukuhamba kwesikhathi esisheshayo, isilinganiso sesibili sithathwa emasontweni ambalwa kamuva, ngemva kwekhilomitha elingu-1 "nxanxathela" ku-A000 yendawo: I-Kawasaki ZX-9R, efanayo ngazo zonke izici (kanye neketanga eligcotshwe kahle!), Ibuyela endaweni yokukala efanayo. . Ngokunengqondo, ama-roller namapuleti athathe indawo yawo, ama-X-Ring seal nawo, kufanele ngokunengqondo sithole izinzuzo ezibaluleke nakakhulu ... Ukushintshela ebhentshini ngandlela-thile kuyaphikisana nalokhu okulindelekile. Ukwanda kwamandla kanye ne-torque kuhliswe ngesigamu kuya ku-110,8 hp. i-torque ecishe ifane iyabonakala. Ungacabanga ukuthi ama-X-Rings aphuka ngokushesha ngenxa yokuncipha kwamaphoyinti okuxhumana? Ngakho-ke izindawo zokungqubuzana zizokwanda, okuholela ekulahlekelweni okulingana nalokhu kwamaketanga e-O-ring? Kunoma ikuphi, kuwukuqaphela okulandela kulokhu kuhlolwa okuqhathanisayo, amaketanga okungqubuzana aphansi agcina ebonise izinzuzo ezingabalulekile kunalokho ebesikulindele, kodwa akholisa ngokwanele kulokhu kuhlolwa ukuze afanele ukunaka kwethu.

Uthi bewazi?

- sikwazile ukukala lokhu ebhentshini le-Fuchs: iketanga eligcotshwe kahle linganciphisa ukulahlekelwa kokudluliselwa kusuka ku-22,8 kuya ku-21,9 mN ngakho-ke buyisela amandla angu-0,8 amahhashi, okungukuthi cishe i-1% yamandla esimweni sokuhlolwa kwethu I-Kawasaki ZX-6R !

- iketango lama-520, lokhu kusho: 5 = chain pitch noma ibanga phakathi kwezixhumanisi ezimbili ezilandelanayo; 2 = ububanzi beketango

Sibonga i-Alliance 2 Wheels neFox ngosizo lwabo lobuchwepheshe.

Lonke ulwazi mayelana namaketanga e-Prokit EK aphansi aphikisanayo lapha.

Iqhubeka nombiko wethu wochungechunge lwezithuthuthu ...

[-hlukanisa: Isevisi-]

Uthi bewazi?

Kungani iketango liguga?

Kunezizathu eziningana zalokhu:

- izimo zomkhathi: imvula "igeza" iketanga, isusa amafutha, kodwa inamathele kuyo, ukungcola komgwaqo, okuhlanganisa isihlabathi, futhi le "slush yomgwaqo" yenza njenge-abrasive enamandla, ibhubhise ngokushesha kakhulu.

- ukuntuleka kokulawula ukungezwani: uma iketanga liqine kakhulu, isibonelo, ama-wheel bearings ikakhulukazi i-shaft yegiya ephumayo ye-gearbox ingahluleka ngokushesha, okuholela ezindlekweni eziphezulu zokulungisa! Ukukhululeka kakhulu, kuzodala ama-jerks futhi kugqoke nakakhulu.

– ngaphandle kokugcotshwa: nakuba iketango line-O'Rings noma i-X'Rings, ezinye izakhi, ikhanda, igiya nengxenye engaphandle yeketango kufanele kugcotshwe (ukungqubuzana okomile = ukugqokwa okusheshisa kakhulu).

- isitayela sokushayela: uma ugijima kuwo wonke amarobhothi futhi wenza ezinye izigigaba ze-acrobatic, imikhawulo yesifunda izobaluleke kakhulu. Ukuhlukunyezwa okunjalo kuzomenza buthaka ngokushesha, bese kumbhubhisa ...

Ukuze uthole okwengeziwe ngokulungiswa bheka futhi isifundo esihle kakhulu sesiteshi ku-ms forum

Isevisi, ukushintshwa

Iseluleko sochwepheshe

Kungcono ukusebenzisa isiphetho se-chain tensioner stroke kanye namazinyo acijile ebhithi ukuze ucabangele ukufaka esikhundleni sesethi yonke yeketango. Ngempela, izingxenye zekhithi (iketango, umqhele, igiya) zahlukana ngamakhilomitha. Uma igiya lokukhiphayo lihlala ligugile, isibonelo ukufaka iketango elisha kuzosheshisa ukuguga kwalo! Ngamafuphi, umbono omuhle wezomnotho ongamanga ...

Uma iketanga lingadingi ukuhlanganisa kabusha, okuyicala elivame kakhulu, ungaphinda ugaye isixhumanisi noma usebenzise i-diverter ukuze uhlukanise ngokushesha yonke into. I-Reassembly nayo iyashesha, kodwa ukunakwa okukhethekile kuzokhokhwa ku-rivet ye-master link kanye ne-centering yesondo elingemuva.

Ngaphambi kokuba ugcobe iketango, ungakhohlwa ukulihlanza: akukho phuzu lokumboza ukungcola okuqoqiwe nokulimaza kakhulu ngamafutha! Isicoci samanzi ashisayo esinengcindezi ephezulu siyasebenza, kodwa izingcindezi eziphakathi kuka-80 no-120 bar zingabangela ukuthi amanzi angene ngisho nakuma-O-rings! Ngakho-ke, khetha ukuhlanza kwebhulashi lakudala nalokho okubizwa ngokuthi "okungenantuthu" noma uwoyela kaphalafini.

Uma isithuthuthu sakho singenaso isitendi esimaphakathi, ujeke wemoto kanye nesitendi eseceleni esinwetshiwe kungasiza ngokuvumela isondo ukuthi lijikeleze endaweni engenalutho futhi lihlale lihlanza futhi ligcoba iketango laso.
