Chipangizo cha ndodo zowongolera ndi trapezoid zagalimoto

Zingwe ndi ndodo zomwe zili pambuyo pa bipod ya makina owongolera nyongolotsi ndi cholumikizira ndi pinion zolumikizira zimapanga chiwongolero cha mawilo owongolera. Ngati makina onse pamwamba pake ali ndi udindo wopanga mphamvu yofunikira, mayendedwe ake ndi kukula kwake, ndiye kuti ndodo zowongolera ndi zida zothandizira zimapanga geometry ya chiwongolero chilichonse chotsatira njira yake. Ntchitoyo si yophweka, ngati tikumbukira kuti mawilo amayenda mozungulira mabwalo awo, omwe amasiyana ndi ma radii ndi kukula kwa njanji ya galimoto. Chifukwa chake, ma angles otembenuka ayenera kukhala osiyana, apo ayi mphira imayamba kutsika, kutha, ndipo galimoto yonseyo sidzayankha mokwanira pakuwongolera.

Kodi makina owongolera magetsi ndi chiyani?

Ma rack ndi pinion ndi ma giya a nyongolotsi ali ndi mapangidwe osiyanasiyana a ndodo zoyendetsa. Muzochitika zachiwiri, ndizozoloŵera kuzitcha trapezoid, ndipo kwa "ndevu" zosavuta zomwe zimachokera ku njanji, dzina lalifupi silinapangidwe.

Ndodo zomangira rack ndi pinion

Kuphweka kwa njanjiyi kunawonekeranso m'mapangidwe a kayendedwe kake. Kupatulapo zida zogwedezeka, zomwe zimagwirizana kwambiri ndi kuyimitsidwa, seti yonseyi imakhala ndi zinthu zinayi - ndodo ziwiri zokhala ndi zida za mpira ndi nsonga ziwiri zowongolera, komanso mawonekedwe a mpira, koma mosiyana ndi malo. Pazambiri zamunthu payekhapayekha, nomenclature ndi yotakata:

• ndodo zowongolera, zomwe nthawi zambiri zimakhala zofanana kumanzere ndi kumanja, zimaperekedwa ndi nsonga zozungulira;
• kuchokera ku zisonkhezero zakunja, zomangira za ndodo zimatetezedwa ndi anthers corrugated, pamtengo nthawi zina wofanana ndi ndodo;
• pakati pa ndodo ndi nsonga pali cholumikizira chala chala ndi mtedza loko;
• chiwongolero chowongolera nthawi zambiri sichimalekanitsidwa, cholondola ndi chithunzi chagalasi cha kumanzere, chimaphatikizapo thupi, pini yokhala ndi sphere, choyikapo, kasupe ndi nsapato za rabara.

Ma geometry amalola kuti mawilo azizungulira mosiyanasiyana, monga tafotokozera pamwambapa.

Chiwongolero cha trapezoid worm kapena screw gearbox

Apa ndipamene zinthu zimakhala zovuta kwambiri:

• ndodo zowongolera nthawi zambiri zimakhala zitatu, kumanzere, kumanja ndi pakati, palinso mapangidwe ovuta;
• ndodo iliyonse imayamba ndi kutha ndi nsonga chiwongolero cha mpira, ndi monyanyira amapangidwa collapsible chifukwa cha kukhalapo kwa chala cholumikizira chofanana chala mu gawo, kotero ife tikhoza kulankhula osati za ndodo ziwiri kwambiri, koma za nsonga zinayi chiwongolero, nthawi zina iwo ali. operekedwa mu mawonekedwe awa, ogawidwa mkati, kunja, kumanzere ndi kumanja;
• Chinthu china chinayambika pamapangidwewo, ndikupanga trapezoid symmetrical, kuchokera kumbali yotsutsana ndi kutalika kwa thupi kuchokera ku bipod ya bokosi la gearbox, lever ya pendulum yokhala ndi bipod yomweyi imayikidwa, kugwedeza kwapakati ndi kwakukulu kumangiriridwa. ku izo.

Trapezium mofananamo imagwirizanitsidwa ndi manja ogwedezeka, okhazikika pa nkhonya za node za hub. Kuzungulira kwa nkhonya kumachitika mumiyendo iwiri ya kuyimitsidwa.

Magulu a mpira wowongolera

Maziko a mfundo zonse za galimotoyo ndi zolumikizira mpira (SHS), zomwe zimatha kuzungulira mozungulira chala ndikugwedezeka m'ndege zonse, kusamutsa mwamphamvu kunjira yoyenera.

M'mapangidwe akale, malupu adapangidwa kuti azitha kukomoka, zomwe zikutanthauza kukonzanso kwawo ndikusintha zitsulo za nayiloni. Ndiye lingaliro ili linasiyidwa, komanso kukhalapo kwa zopangira mafuta pa lupu kuti abwezeretse mafutawo. Nsongayi imatengedwa kuti ndi yogwiritsidwa ntchito, yosavuta kusintha komanso yotsika mtengo, choncho kukonza kumaonedwa kuti n'kosatheka. Pa nthawi yomweyo, opaleshoni wokhazikika jekeseni wa hinges anachotsedwa mndandanda wa kukonza. Chifukwa chake ndiyodalirika komanso yotetezeka, kuyendetsa ndi hinge yokonzedwa kumadzaza ndi kulumikizidwa kwamphamvu pa liwiro ndi zotsatira zoyipa.

Mlandu wanthawi zonse wokonzanso ndikuwongolera kuyendetsa ndikusintha malupu onse, kenako dongosolo limasinthidwa kwathunthu ndipo chitetezo chimatsimikizika. Ndikoyenera kumvetsera chitetezo cha zophimba mphira poyang'ana chassis panthawi yokonza chizolowezi. Kukhumudwa kwa nsonga za mpira nthawi yomweyo kumabweretsa kulephera kwawo, popeza mkati mwake muli mafuta omwe amakopa mwachangu fumbi ndi madzi. Kubwerera kumbuyo kumawonekera mu nsonga, chassis imayamba kugogoda, zimakhala zoopsa kuyendetsa mopitilira.
