Njengowona mthwalo ongundoqo-wecandelo elithwele izithuthi zemizi-mveliso, umgangatho wofakelo lwerim yamavili uchaphazela ngqo ukhuseleko lwesithuthi, uzinzo lokusebenza kunye nobomi benkonzo yeerim. Iinkqubo zokufakela ezichanekileyo kunye neenkqubo zokusebenza eziqhelekileyo zingundoqo ekuphepheni iingozi zokhuseleko kunye nokuqinisekisa ukusebenza kakuhle kwemveliso. Ukunceda abathengi ekufakeni iirimu zamavili ngokuchanekileyo kunye nokuthintela imiba efana nokuguqulwa, ukukhulula kunye nokuvuza komoya okubangelwa kufakelo olungafanelekanga, siya kuchaza ngokufutshane izikhokelo zofakelo ukunceda wonke umsebenzisi agqibe inkqubo yokufakela ngokukhuselekileyo nangokufanelekileyo.
Amalungiselelo Phambi koFakelo
Izixhobo:Lungisa iziklintshi ezifanelekileyo, isitshisi setorque, into yokutshintsha itayara, igeyiji yoxinzelelo lwamatayara, izixhobo zokucoca (iibhrashi, amalaphu) kunye nezixhobo zokukhusela (iiglavu, iiglasi zokhuseleko). I-torque wrench kufuneka ilinganiswe kwangaphambili ukuze kuqinisekiswe ukufundwa kwetorque echanekileyo kwaye kuthintele iibholithi ukuba zikhululeke okanye zonakaliswe ngenxa yokutenxa kwetorque;
Qwalasela amacandelo:Qinisekisa ukucaciswa kunye neemodeli zamacandelo afana neerim, amatayara, iibholithi zamavili, amandongomane kunye ne-O{0}}amakhonkco ukuqinisekisa ukuba ahambelana ngokupheleleyo nemodeli yesithuthi kunye neerim parameters. Kwimizila yesiko, ukongeza uqinisekise imilinganiselo yesiko kunye nokuhambelana kwesakhiwo kunye nesithuthi ukukhusela ukusetyenziswa kweendawo ezingahambelaniyo;
Ukuhlola:Hlola ungqameko ngalunye ngokweziphene ezifana nokonakala, iintanda okanye umhlwa; khangela ukuba intsimbi yetayara ilungile kwaye ayonakaliswa; qinisekisa ukuba iibholithi kunye namandongomane azikhulwanga okanye azikhubazekanga; kwaye uqinisekise ukuba izitywina azigugi okanye zonakaliswa. Ukuba kukho imiba echongiweyo, buyisela amacandelo ngokukhawuleza; ukusetyenziswa kwamalungu akumgangatho ophantsi wofakelo akuvumelekanga ngokungqongqo.
Inkqubo yoFakelo
Inyathelo 1: Ukucoca kunye nokuLungisa. Sebenzisa izixhobo zokucoca ukucoca ngokucokisekileyo indawo yokunyuka komphetho wevili, i-flange surface ye-hub, kunye nemingxuma yebholiti, ukususa naluphi na uthuli, igrisi, irusi kunye nenkunkuma phezu komhlaba. Qinisekisa ukuba umphezulu oxhomileyo usicaba kwaye ucocekile ukunqanda ungcoliseko ekubangeleni ukususwa kofakelo olugqithisileyo, okunokubeka esichengeni isiphumo sokhuseleko. Kwangaxeshanye, coca intsimbi yetayara kwaye ujonge ukuba indawo yokudibana phakathi kwentsimbi kunye nesondo ikwirimu ayichanekanga.
Inyathelo 2: Ukudityaniswa kweTire kunye nesondo. Beka itayara ngokukhuselekileyo kwisixhobo sokutshintsha ivili kwaye, ngokulandela iinkqubo ezisemgangathweni, nyusa ivili kwivili, uqinisekise ukuba izitulo zamaso ziqinile kumphetho wevili ukunqanda ukungahambi kakuhle okanye ukuminxeka. Emva kokuhlanganisana, jonga ukulingana phakathi kwevili kunye nevili ukuqinisekisa ukuba akukho mdlalo okanye ukulungelelaniswa.
Inyathelo lesi-3: Faka ivili levili. Lungelelanisa umphetho wevili odityanisiweyo kunye ne-hub flange, ulungelelanisa indawo yayo ukuze imingxunya yevili yebholithi ilungelelaniswe ngokuchanekileyo kunye nemingxunya ye-hub bolt. Isandla-qinisa zonke iibholiti kunye namandongomane ukuqinisekisa ukhuseleko lwangaphambili kwaye uthintele umphetho wevili ukuba ungashukumi.
Inyathelo lesi-4: Ukuqinisa iTorque. Usebenzisa i-calibrated torque wrench, qinisa iibholithi kunye namandongomane ngokulungeleleneyo kwizigaba ezininzi, ulandela i-diagonal criss{2}}ipateni yomnqamlezo. Ukuthobela ngokungqongqo imigangatho yetorque echazwe ngumenzi wesithuthi okanye incwadana yerim. Uluhlu lwetorque yeerimu zemizi-mveliso ngokubanzi luqhelekile ukuba yi-120–180 N · m. Musa ukuziqinisa ngokugqithisileyo (oku kunokubangela ukwaphuka kwebholithi okanye ukuguquka kwerim) okanye uqinise ngaphantsi (oku kunokukhokelela ekuyekeleni xa uqhuba).
Inyathelo lesi-5: Ukunyuka kwamaxabiso kunye nokuhlolwa. Xa ukufakela kugqityiwe, sebenzisa igeyiji yoxinzelelo lwetayara ukujonga uxinzelelo lwetayara kwaye ululungelelanise kumgangatho ochaziweyo womenzi. Kwangaxeshanye, jonga umdibaniso phakathi komphetho kunye netayara ukuba akukho nakuphi na ukuvuza komoya, kwaye ujonge ukuba umphetho uyashukuma okanye uyashukuma. Kuphela kusemva kokuqinisekisa ukuba akukho ziphazamiso ekufuneka isithuthi sifakwe emsebenzini.
UFakelo lwamanyathelo
1. Ngaphantsi kweemeko kufuneka iibholiti kunye namantongomane eenkcazo ezahlukeneyo okanye izinto ezixutywe. Iimodeli ezahlukeneyo zerim kufuneka zifakelwe izibophelelo zeenkcukacha ezihambelanayo; iirimu ezenziweyo{2}ezenziweyo kufuneka zisebenzise iziqhoboshi ezizinikeleyo zomenzi;
2. Ngexesha lofakelo, qinisekisa ukuba i-rim mounting surface igungxulwa ngokupheleleyo ne-hub flange, ingabi nazikhewu okanye ilungelelanise kakuhle. Ukuba kukho umsantsa, khangela nayiphi na inkunkuma engacacanga okanye imiba yokuhambelana namacandelo;
3. Ukuqinisa iTorque kufuneka kulandele idiagonal criss-ulandelelwano lomnqamlezo, uqina kancinci kancinci kwizigaba ezi-2–3 ukunqanda uxinzelelo olungalinganiyo olubangelwa kukuqiniswa nje kanye;
4. Emva kofakelo, uvavanyo kufuneka luqhutywe. Emva kokuqhuba iikhilomitha ezi-1 ukuya kwezi-2 ngesantya esiphantsi, misa isithuthi ukujonga ukuqina kweebholiti kunye namantongomane, kwaye{4}uqinisekise kwakhona i-torque usebenzisa i-torque wrench ukuqinisekisa ukuba akukho ukukhululeka;
5. Kwizithuthi ebezingasetyenziswa ixesha elide okanye ezilandela ukutshintshwa kwerim yevili, uxinzelelo lwetayara kunye nokuqina kwebholithi kufuneka zitshekishwe rhoqo ngethuba lokuqala lokuqhuba, kwaye uhlengahlengiso lwenziwe ngokukhawuleza.
Isishwankathelo
Ufakelo oluchanekileyo nolufanelekileyo lubalulekile ekuqinisekiseni ukuba iirim zamavili zisebenza ngokusemandleni azo ngokupheleleyo kunye nokuqinisekisa ukhuseleko lokuqhuba. Ngoko ke sincoma ukuba bonke abasebenzisi balandele ngokungqongqo imiyalelo kwesi sikhokelo ukuqinisekisa ukuba zonke inyathelo zenziwa ngokuhambelana neenkcukacha. Oku kuya kuthintela ngempumelelo iingozi zokhuseleko ezibangelwa kufakelo olungafanelekanga, ukwandisa umthwalo{2}}umthamo wokuthwala iirimu zamavili, ukwandisa ubomi bawo benkonzo, kunye nokubonelela ngesiseko esiluqilima sokusebenza okuzinzileyo nokukhuselekileyo kwesithuthi.
