V-drive bhandi: yakavimbika dhiraivha yezvikamu uye zvishandiso
Magiya akavakirwa parubha V-mabhandi anoshandiswa zvakanyanya kutyaira injini zvikamu uye mukufambiswa kwemidziyo yakasiyana.Verenga zvese nezve drive V-mabhandi, marudzi avo aripo, maitiro ekugadzira uye hunhu, pamwe nekusarudzwa kwakaringana uye kutsiva mabhandi mune chinyorwa.
Chinangwa uye mabasa eV-mabhandi
Dhiraivha V-bhandi (fan bhandi, bhandi remotokari) irabha-jira risingaperi (rakakungurutswa mumhete) bhandi re trapezoidal (V-yakaumbwa) muchinjiko-chikamu, rakagadzirirwa kuendesa torque kubva ku crankshaft yesimba remagetsi kuenda kumayuniti akaiswa. , uyewo pakati pezvikamu zvakasiyana-siyana zvemigwagwa, michina yekurima, maturusi emuchina, maindasitiri uye kumwe kuisirwa.
Bhanhire rebhandi, rinozivikanwa kumunhu kwemakore anopfuura zviuru zviviri, rine zvipingamupinyi zvakawanda, pakati payo matambudziko makuru anokonzerwa nekutsvedza uye kukanganisa kwemagetsi pasi pemitoro yakakura.Kumwero mukuru, matambudziko aya anogadziriswa mumabhandi ane chimiro chakakosha - V-shaped (trapezoidal).
V-mabhandi ane huwandu hwakawanda hwekushandisa:
● Mumagetsi emagetsi emotokari nemimwe midziyo yekufambisa kutenderera kubva ku crankshaft kusvika kune zvakasiyana-siyana - fan, jenereta, pombi yekufambisa simba nezvimwe;
● Mukufambisa nemadhiraivha emugwagwa unozvifambisa wega uye unotevedza, zvekurima uye zvakakosha;
● Mukufambisa uye madhiraivha emichina yakamira, maturusi emuchina nemimwe midziyo.
Mabhandi anoiswa mukupfeka kwakanyanya uye kukuvadzwa panguva yekushanda, izvo zvinoderedza kuvimbika kweiyo V-belt kutapurirana kana kudzima zvachose.Kuti uite sarudzo yakarurama yebhanhire idzva, unofanirwa kunzwisisa marudzi aripo ezvigadzirwa izvi, maitiro avo uye maitiro.
Ndapota cherechedzai: nhasi kune V-mabhandi uye V-ribbed (multi-strand) mabhanhire ane maitiro akasiyana.Ichi chinyorwa chinotsanangura chete akajairwa V-mabhandi.

Mhando dzekutyaira V-mabhandi
Kune mhando mbiri huru dzeV-mabhandi:
- Smooth drive mabhandi (yakajairika kana AV);
- Nguva yekutyaira mabhandi (AVX).
Bhanhire rakatsetseka ndiro mhete yakavharwa ye trapezoidal cross-section ine nzvimbo yekushanda yakatsetseka pamwe chete nehurefu hwose.Pamusoro pekushanda kwe (matete) mabhanhire ekugadzirisa nguva, mazino ezvinyorwa zvakasiyana-siyana anoshandiswa, izvo zvinopa bhanhire kuwedzera elasticity uye inobatsira pakuwedzera kwehupenyu hwechigadzirwa chose.
Mabhandi akapfava anowanikwa mushanduro mbiri:
- Execution I - yakamanikana zvikamu, chiyero chenheyo yakafara kusvika pakukwirira kwebhanhire rakadaro riri muhupamhi hwe1.3-1.4;
- Kuuraya II - zvikamu zvakajairika, chiyero chehwaro hwakakura kusvika pakukwirira kwebhanhire rakadaro riri pakati pe 1.6-1.8.
Mabhandi anotsvedzerera anogona kunge ane dhizaini upamhi hwe8.5, 11, 14 mm (zvikamu zvakamanikana), 12.5, 14, 16, 19 uye 21 mm (zvikamu zvakajairika).Izvo zvinodikanwa kuratidza kuti dhizaini upamhi inoyerwa pazasi pehupamhi hwaro hwebhanhire, saka zviyero zviri pamusoro zvinoenderana nehupamhi hwehupamhi hwaro hwe10, 13, 17 mm uye 15, 17, 19, 22, 25 mm, zvichiteerana.
Mabhandi ekudhiraivha emuchina wekurima, maturusi emuchina uye akasiyana mirawo ekuisa ane yakawedzera huwandu hwehukuru hwaro, kusvika 40 mm.Dhiraivha mabhandi emagetsi emagetsi emidziyo yemotokari anowanikwa mumatatu matatu - AV 10, AV 13 uye AV 17.
Fani V-mabhandi
V-belt transmissions
Mabhandi enguva anowanikwa chete muRudzi I (zvikamu zvakamanikana), asi mazino anogona kunge ari matatu akasiyana:
● Sarudzo 1 - wavy (sinusoidal) mazino ane radius yakafanana yezino uye kureba kwepakati;
● Sarudzo 2 - ine zino rakatsetseka uye radius interdental chinhambwe;
● Sarudzo yechitatu - ine radius (yakatenderedzwa) zino uye kureba kwepakati pemazino chinhambwe.
Mabhandi enguva anouya mumasikisi maviri chete - AVX 10 uye AVX 13, saizi imwe neimwe inowanikwa nemhando dzose dzemazino matatu (saka kune marudzi matanhatu makuru emabhandi enguva).
V-mabhandi emarudzi ese anogadzirwa mune akati wandei mavhezheni zvinoenderana nemaitiro eiyo static magetsi kuchaja kuunganidza uye mamiriro ekunze ekushanda.
Zvinoenderana nehunhu hwekuunganidzwa kwe electrostatic charge, mabhandi ndeaya:
● Zvakajairika;
● Antistatic - ine simba rakaderedzwa rekuunganidza mari.
Zvinoenderana nemamiriro ekunze, mabhanhire ndeaya:
● Kunzvimbo dzine mamiriro ekunze anopisa (ane tembiricha yekushanda kubva -30 ° C kusvika + 60 ° C);
● Kunzvimbo dzine mamiriro ekunze anodziya (uyewo nekushanda tembiricha kubva -30 ° C kusvika + 60 ° C);
● Kunzvimbo dzine mamiriro ekunze anotonhora (nekushanda kwekushisa kubva -60 ° C kusvika + 40 ° C).
Kurongeka, maitiro uye kushivirira kweV-mabhandi emarudzi akasiyana-siyana anotungamirirwa nemitemo yepamba uye yepasi rose, kusanganisira GOST 5813-2015, GOST R ISO 2790-2017, GOST 1284.1-89, GOST R 53841-2010 uye magwaro akafanana.
