Ibhande le-V-drive: ukushayela okuthembekile kwamayunithi nemishini

Amagiya asuselwe kumabhande enjoloba angu-V asetshenziswa kakhulu ukushayela amayunithi enjini nasekudluliselweni kwemishini ehlukahlukene.Funda konke mayelana namabhande e-V-drive, izinhlobo zawo ezikhona, izici zokuklama nezici, kanye nokukhetha okulungile nokushintshwa kwamabhande esihlokweni.

Inhloso kanye nemisebenzi ye-V-belt

I-V-belt (ibhande labalandeli, ibhande lemoto) iyibhande lerabha lendwangu engapheli (eligoqelwe eringini) lesiphambano se-trapezoidal (emise okwe-V), eliklanyelwe ukudlulisa i-torque isuka ku-crankshaft yesikhungo samandla iye kumayunithi agingqiwe. , kanye naphakathi kwamayunithi ahlukahlukene omgwaqo, imishini yezolimo, amathuluzi emishini, izimboni nokunye ukufakwa.

I-belt drive, eyaziwa ngumuntu iminyaka engaphezu kwezinkulungwane ezimbili, inezithiyo eziningana, phakathi kwazo izinkinga ezinkulu kakhulu ezibangelwa ukushelela kanye nokulimala kwemishini ngaphansi kwemithwalo ephezulu.Ngokwezinga elikhulu, lezi zinkinga zixazululwa ngamabhande anephrofayili ekhethekile - ene-V (trapezoidal).

Amabhande e-V anezinhlobonhlobo zezinhlelo zokusebenza:

● Ezimbonini zamandla ezimoto nezinye izinto zokusebenza zokudlulisa ukuzungeza kusuka ku-crankshaft kuya kumathuluzi ahlukahlukene - isiphephetha-moya, ijeneretha, iphampu yokuqondisa amandla nokunye;
● Ekuhanjisweni nasekushayeleni umgwaqo ozishayelelayo kanye nezilandelanayo, izinsiza zezolimo nezikhethekile;
● Ekuthumeleni nasekushayeleni imishini emile, amathuluzi emishini nezinye izinto zokusebenza.

Amabhande abhekene nokuguga okukhulu kanye nokulimala ngesikhathi sokusebenza, okunciphisa ukuthembeka kokudluliswa kwe-V-belt noma kukhubaze ngokuphelele.Ukuze ukhethe kahle ibhande elisha, kufanele uqonde izinhlobo ezikhona zale mikhiqizo, ukuklama nezici zabo.

Sicela uqaphele: namuhla kukhona amabhande e-V kanye ne-V-ribbed (multi-strand) anemiklamo ehlukene.Lesi sihloko sichaza amabhande e-V ajwayelekile kuphela.

Izinhlobo zama-V-belt

Kunezinhlobo ezimbili eziyinhloko zamabhande e-V:

Amabhande okushayela abushelelezi (ejwayelekile noma i-AV);
Amabhande okushayela isikhathi (AVX).

Ibhande elibushelelezi liyindandatho evaliwe ye-trapezoidal cross-section enendawo yokusebenza ebushelelezi kubo bonke ubude.Endaweni yokusebenza yamabhande esikhathi (amancane), amazinyo amaphrofayili ahlukahlukene asetshenziswa, anikeza ibhande ukwanda kwe-elasticity futhi abambe iqhaza ekwandiseni impilo yomkhiqizo wonke.

Amabhande abushelelezi atholakala ngezinguqulo ezimbili:

Ukubulawa I - izigaba ezincane, isilinganiso sesisekelo esibanzi ukuphakama kwebhande elinjalo lisebangeni le-1.3-1.4;
Ukubulawa II - izigaba ezijwayelekile, isilinganiso sesisekelo esibanzi kuya ekuphakameni kwebhande elinjalo lisebangeni le-1.6-1.8.

Amabhande abushelelezi angaba nobubanzi bomklamo obujwayelekile obungu-8.5, 11, 14 mm (izingxenye eziwumngcingo), 12.5, 14, 16, 19 kanye no-21 mm (izingxenye ezivamile).Kudingekile ukukhombisa ukuthi ububanzi bomklamo bulinganiswa ngaphansi kwesisekelo esibanzi sebhande, ngakho-ke ubukhulu obungenhla buhambisana nobubanzi besisekelo esibanzi se-10, 13, 17 mm kanye ne-15, 17, 19, 22, 25 mm, ngokulandelana.

Amabhande okushayela emishini yezolimo, amathuluzi emishini nokufakwa okuhlukahlukene okumile anobubanzi obunwetshiwe bosayizi basezindaweni, kufika ku-40 mm.Amabhande okushayela emishini yamandla ezinto zezimoto atholakala ngosayizi abathathu - AV 10, AV 13 kanye ne-AV 17.

Ukuhanjiswa kwebhande le-V

Amabhande esikhathi atholakala kuphela ohlotsheni I (izigaba eziwumngcingo), kodwa amazinyo angaba ngokwehluka okuthathu:

● Inketho 1 - amazinyo angamagagasi (sinusoidal) anendawo efanayo yezinyo kanye nebanga phakathi kwamazinyo;
● Indlela yesi-2 - enezinyo eliyisicaba kanye nebanga eliphakathi kwamazinyo;
● Inketho yesi-3 - ngezinyo eliyiradiyasi (eliyindilinga) kanye nebanga eliphakathi nendawo eliyisicaba.

Amabhande esikhathi afika ngosayizi ababili kuphela - i-AVX 10 ne-AVX 13, usayizi ngamunye utholakala nazo zonke izinhlobo ezintathu zamazinyo (ngakho kunezinhlobo eziyisithupha eziyinhloko zamabhande esikhathi).

Amabhande e-V azo zonke izinhlobo akhiqizwa ngezinguqulo eziningana ngokuya ngezakhiwo zokuqoqwa kweshaja kagesi omile kanye nezindawo zokusebenza zezulu.

Ngokusho kwezakhiwo zokuqoqwa kwe-electrostatic charge, amabhande yilawa:

● Okuvamile;
● I-Antistatic - enekhono elincishisiwe lokuqongelela imali.

Ngokusho kwezindawo zezulu, amabhande yilawa:

● Ezindaweni ezinesimo sezulu esishisayo (ezinamazinga okushisa okusebenza asuka ku -30 ° C kuya ku- + 60 ° C);
● Ezindaweni ezinesimo sezulu esipholile (futhi namazinga okushisa okusebenza kusuka ku -30 ° C kuya ku- + 60 ° C);
● Ezindaweni ezinesimo sezulu esibandayo (ezinamazinga okushisa okusebenza ukusuka ku -60 ° C kuya ku- + 40 ° C).

Ukuhlukaniswa, izici nokubekezelelana kwamabhande e-V ezinhlobo ezihlukahlukene kulawulwa izindinganiso zasekhaya nezamazwe ngamazwe, kuhlanganise ne-GOST 5813-2015, GOST R ISO 2790-2017, GOST 1284.1-89, GOST R 53841-2010 kanye nemibhalo ehlobene.
