V-drive lamba: kuyendetsa kodalirika kwa mayunitsi ndi zida
Magiya opangidwa ndi malamba a V-rabara amagwiritsidwa ntchito kwambiri poyendetsa mayunitsi a injini komanso potumiza zida zosiyanasiyana.Werengani zonse za ma drive V-malamba, mitundu yawo yomwe ilipo, mawonekedwe ake ndi mawonekedwe, komanso kusankha kolondola ndikusintha malamba m'nkhaniyi.
Cholinga ndi ntchito za V-malamba
Lamba woyendetsa V-lamba (fan lamba, lamba wamagalimoto) ndi lamba wansalu wopanda malire (wokulungidwa mu mphete) lamba wa trapezoidal (V-wooneka ngati V), wopangidwa kuti azitumiza torque kuchokera ku crankshaft yamagetsi kupita ku mayunitsi okwera. , komanso pakati pa magawo osiyanasiyana amsewu, makina aulimi, zida zamakina, mafakitale ndi makhazikitsidwe ena.
Kuyendetsa lamba, komwe kumadziwika kwa munthu kwa zaka zoposa zikwi ziwiri, kumakhala ndi zovuta zingapo, zomwe zimakhala zovuta kwambiri chifukwa cha kutsetsereka ndi kuwonongeka kwa makina pansi pa katundu wambiri.Pamlingo waukulu, mavutowa amathetsedwa mu malamba okhala ndi mbiri yapadera - V-woboola pakati (trapezoidal).
V-malamba ali ndi ntchito zosiyanasiyana:
● M'mafakitale amagetsi a galimoto ndi zipangizo zina zotumizira mozungulira kuchokera ku crankshaft kupita ku zipangizo zosiyanasiyana - fan, jenereta, mpope woyendetsa magetsi ndi zina;
● Kutumiza ndi kuyendetsa misewu yodziyendetsa yokha komanso yodutsamo, zaulimi ndi zida zapadera;
● Potumiza ndi kuyendetsa makina oima, zida zamakina ndi zida zina.
Malamba amawonongeka kwambiri ndikuwonongeka panthawi yogwira ntchito, zomwe zimachepetsa kudalirika kwa kufalikira kwa V-lamba kapena kuzimitsa kwathunthu.Kuti mupange chisankho choyenera cha lamba watsopano, muyenera kumvetsetsa mitundu yomwe ilipo ya mankhwalawa, mapangidwe awo ndi makhalidwe awo.
Chonde dziwani: lero pali malamba a V ndi V-ribbed (multi-strand) omwe ali ndi mapangidwe osiyanasiyana.Nkhaniyi ikufotokoza ma V-malamba okha.
Malamba oyendetsedwa ndi V-malamba V
Mitundu yamagalimoto a V-malamba
Pali mitundu iwiri ikuluikulu ya malamba a V:
- malamba oyenda bwino (wamba kapena AV);
- Malamba oyendetsa nthawi (AVX).
Lamba wosalala ndi mphete yotsekedwa ya trapezoidal cross-section ndi yosalala yogwira ntchito pamtunda wonse.Pamalo ogwirira ntchito (opapatiza) malamba a nthawi, mano amitundu yosiyanasiyana amagwiritsidwa ntchito, omwe amapatsa lamba kuwonjezereka komanso kumathandizira kukulitsa moyo wazinthu zonse.
Malamba osalala amapezeka m'mitundu iwiri:
- Kupha I - zigawo zopapatiza, chiŵerengero cha m'munsi waukulu mpaka kutalika kwa lamba woteroyo chimakhala cha 1.3-1.4;
- Kupha II - magawo abwinobwino, chiŵerengero cha m'munsi mwake mpaka kutalika kwa lamba woteroyo chimakhala cha 1.6-1.8.
Malamba osalala amatha kukhala ndi makulidwe odziwika bwino a 8.5, 11, 14 mm (magawo opapatiza), 12.5, 14, 16, 19 ndi 21 mm (magawo wamba).Ndikoyenera kusonyeza kuti mapangidwe m'lifupi mwake amayezedwa m'munsimu lonse lamba, kotero miyeso pamwamba zikugwirizana ndi m'lifupi m'munsi lonse la 10, 13, 17 mm ndi 15, 17, 19, 22, 25 mm, motsatira.
Malamba oyendetsa makina aulimi, zida zamakina ndi makhazikitsidwe osiyanasiyana oyima amakhala ndi makulidwe oyambira, mpaka 40 mm.Malamba oyendetsa magetsi a zida zamagalimoto akupezeka m'miyeso itatu - AV 10, AV 13 ndi AV 17.
Mafani a V-malamba
Kutumiza kwa lamba wa V
Malamba a nthawi akupezeka mu Type I yokha (gawo lopapatiza), koma mano amatha kukhala amitundu itatu:
● Njira 1 - mano a wavy (sinusoidal) okhala ndi utali wofanana wa dzino ndi mtunda wapakati;
● Njira 2 - ndi dzino lathyathyathya ndi utali wotalikirana pakati;
● Njira 3 - ndi dzino lozungulira (lozungulira) ndi mtunda wosalala pakati pa mano.
Malamba anthawi amabwera mumitundu iwiri yokha - AVX 10 ndi AVX 13, makulidwe aliwonse amapezeka ndi mitundu yonse itatu ya mano (kotero pali mitundu isanu ndi umodzi ya malamba anthawi).
Malamba a V amitundu yonse amapangidwa m'mitundu ingapo molingana ndi momwe amapangira magetsi osasunthika komanso madera omwe amagwirira ntchito.
Malingana ndi katundu wa kudzikundikira kwa electrostatic charge, malamba ndi:
● Wamba;
● Antistatic - ndi kuchepetsedwa luso kudziunjikira malipiro.
Malingana ndi madera a nyengo, malamba ndi:
● Kwa madera omwe ali ndi nyengo yotentha (yomwe ili ndi kutentha kwa -30 ° C mpaka + 60 ° C);
● Kwa madera omwe ali ndi nyengo yabwino (komanso ndi kutentha kwa ntchito kuchokera -30 ° C mpaka + 60 ° C);
● Kwa madera omwe ali ndi nyengo yozizira (yomwe imagwira ntchito kutentha kuchokera -60 ° C mpaka + 40 ° C).
Magulu, mawonekedwe ndi kulolerana kwa V-malamba amitundu yosiyanasiyana amayendetsedwa ndi miyezo yapakhomo ndi yapadziko lonse lapansi, kuphatikiza GOST 5813-2015, GOST R ISO 2790-2017, GOST 1284.1-89, GOST R 53841-2010 ndi zolemba zofananira.
