Ibhanti ye-V-drive: ukuqhuba okuthembekileyo kweeyunithi kunye nezixhobo
Iigiya ezisekelwe kwi-rubber V-ibhanti zisetyenziswa ngokubanzi ukuqhuba iiyunithi ze-injini kunye nokuhanjiswa kwezixhobo ezahlukeneyo.Funda konke malunga neebhanti ze-V zokuqhuba, iintlobo zazo ezikhoyo, iimpawu zoyilo kunye neempawu, kunye nokukhetha okuchanekileyo kunye nokutshintshwa kwamabhanti kwinqaku.
Injongo kunye nemisebenzi ye-V-belt
I-V-belt ye-drive (ibhanti lefeni, ibhanti lemoto) yirabha-ilaphu elingapheliyo (iqengqeleke kwindandatho) ibhanti yetrapezoidal (emilo engu-V) yecandelo elinqamlezayo, eyenzelwe ukuhambisa i-torque ukusuka kwi-crankshaft yeplanti yamandla ukuya kwiiyunithi ezinyusiweyo. , kunye naphakathi kweeyunithi ezahlukeneyo zendlela, oomatshini bezolimo, izixhobo zoomatshini, iifektri kunye nolunye ufakelo.
Ibhanti yebhanti, eyaziwayo kumntu ngaphezu kweminyaka engamawaka amabini, ineengxaki ezininzi, phakathi kwazo ezona ngxaki zinkulu zibangelwa yi-slippage kunye nomonakalo womatshini phantsi kwemithwalo ephezulu.Ubukhulu becala, ezi ngxaki zixazululwa kwiibhanti ezineprofayili ekhethekileyo - i-V-shaped (trapezoidal).
Iibhanti ze-V zinoluhlu olubanzi lwezicelo:
● Kwizixhobo zamandla zemoto kunye nezinye izixhobo zokuhanjiswa kokujikeleza ukusuka kwi-crankshaft ukuya kwizixhobo ezahlukeneyo - i-fan, i-generator, impompo yokulawula amandla kunye nabanye;
● Kuthutho kunye nokuqhubela phambili kwendlela eziqhubayo neziqhutywayo, izixhobo zolimo kunye nezixhobo ezizodwa;
● Kuthumelo kunye nokuqhuba koomatshini abamileyo, izixhobo zoomatshini kunye nezinye izixhobo.
Iibhanti ziphantsi kokugqithisa okukhulu kunye nomonakalo ngexesha lokusebenza, okunciphisa ukuthembeka kwe-V-belt transmission okanye ukuyikhubaza ngokupheleleyo.Ukwenza ukhetho olufanelekileyo lwebhanti entsha, kufuneka uqonde iintlobo ezikhoyo zezi mveliso, ukuyila kwazo kunye neempawu.
Nceda uqaphele: namhlanje kukho iibhanti ze-V kunye ne-V-ribbed (i-multi-strand) ezinemibala eyahlukeneyo.Eli nqaku lichaza kuphela iibhanti ze-V eziqhelekileyo.
Iibhanti zeV-V eziqhutywayo
Iintlobo zokuqhuba iibhanti ze-V
Kukho iindidi ezimbini eziphambili ze-V-belt:
- Iibhanti zokuqhuba ezigudileyo (eziqhelekileyo okanye i-AV);
- Iibhanti zokuqhuba ixesha (AVX).
Ibhanti eligudileyo liyindandatho evaliweyo ye-trapezoidal cross-section kunye nomsebenzi osebenzayo kunye nobude bonke.Kumsebenzi osebenzayo weebhanti zexesha (ezimxinwa), amazinyo eeprofayili ezahlukeneyo asetyenziswa, ezinika ibhanti ukwanda kwe-elasticity kunye negalelo ekwandiseni ubomi bemveliso yonke.
Iibhanti ezigudileyo ziyafumaneka kwiinguqulelo ezimbini:
- Ukubulawa I - amacandelo amancinci, umlinganiselo wesiseko esibanzi ukuya ekuphakameni kwebhanti enjalo ulele kuluhlu lwe-1.3-1.4;
- Ukubulawa kwe-II - amacandelo aqhelekileyo, umlinganiselo wesiseko esibanzi ukuya kubude bebhanti enjalo ulele kuluhlu lwe-1.6-1.8.
Amabhanti agudileyo anokuba nobubanzi boyilo oluqhelekileyo lwe-8.5, 11, 14 mm (amacandelo amxinwa), 12.5, 14, 16, 19 kunye ne-21 mm (amacandelo aqhelekileyo).Kuyimfuneko ukubonisa ukuba ububanzi boyilo bulinganiswa ngaphantsi kwesiseko esibanzi sebhanti, ngoko ke imilinganiselo engentla ihambelana nobubanzi besiseko esibanzi se-10, 13, 17 mm kunye ne-15, 17, 19, 22, 25 mm, ngokulandelelanayo.
Amabhanti okuqhuba oomatshini bezolimo, izixhobo zoomatshini kunye nofakelo olwahlukeneyo olumileyo lunoluhlu olwandisiweyo lobungakanani besiseko, ukuya kuthi ga kwi-40 mm.Iibhanti zokuqhuba zezixhobo zombane zezixhobo zemoto zifumaneka ngokobukhulu obuthathu - AV 10, AV 13 kunye ne-AV 17.
Umlandeli we-V-ibhanti
Ukuhanjiswa kwebhanti ye-V
Amabhanti exesha afumaneka kuphela kuHlobo lwe-I (amacandelo amxinwa), kodwa amazinyo anokuba zizinto ezintathu:
● Ukhetho loku-1 - amazinyo angama-wavy (sinusoidal) aneradiyasi efanayo yezinyo kunye nomgama phakathi kwamazinyo;
● Ukhetho lwesi-2 - ngezinyo elisicaba kunye nomgama ophakathi kwamazinyo;
● Ukhetho lwesi-3 - ngezinyo elijikelezayo (elingqukuva) kunye nomgama othe tyaba phakathi kwamazinyo.
Amabhanti exesha afika ngeesayizi ezimbini kuphela - i-AVX 10 kunye ne-AVX 13, isayizi nganye ifumaneka kuzo zonke iintlobo ezintathu zamazinyo (ngoko kukho iindidi ezintandathu eziphambili zamabhanti exesha).
Iibhanti ze-V zazo zonke iintlobo zenziwa kwiinguqulelo ezininzi ngokweepropati zokuqokelela intlawulo yombane we-static kunye nemimandla yemozulu yokusebenza.
Ngokweempawu zokuqokelelwa kwentlawulo ye-electrostatic, iibhanti zezi:
● Ngokwesiqhelo;
● I-Antistatic - ngekhono elincitshisiweyo lokuqokelela intlawulo.
Ngokwemimandla yemozulu, iibhanti zezi:
● Kwiindawo ezinemozulu yetropiki (kunye namaqondo okushisa asebenzayo ukusuka -30 ° C ukuya + 60 ° C);
● Kwiindawo ezinemozulu epholileyo (kunye namaqondo okushisa asebenzayo ukusuka -30 ° C ukuya + 60 ° C);
● Kwiindawo ezinemozulu ebandayo (kunye namaqondo okushisa asebenzayo ukusuka -60 ° C ukuya + 40 ° C).
Ukwahlula, iimpawu kunye nokunyamezela kweebhanti ze-V zeentlobo ezahlukeneyo zilawulwa yimigangatho yasekhaya nakwamanye amazwe, kuquka i-GOST 5813-2015, iGOST R ISO 2790-2017, iGOST 1284.1-89, iGOST R 53841-2010 kunye namaxwebhu ahambelanayo.
