Kodi chilolezo ndi chiyani ndipo chivomerezo chimayesedwa bwanji?

Chilolezo chonyamula chozungulira ndi kuchuluka kwa ntchito yomwe imagwira ling'i imodzi m'malo ndi inayo munjira yowala kapena axial. Ntchito yayikulu motsatira malangizo a radial imatchedwa radial chilolezo, ndipo ntchito yayikulu kwambiri yolumikizira axial imatchedwa axial chilolezo. Nthawi zambiri, chilolezo chokulirapo, chokulirapo chilema, komanso mosemphanitsa. Malinga ndi momwe akumvera, chilolezocho chimatha kugawidwa m'njira zitatu zotsatirazi:

I. Chilolezo choyambirira

Chilolezo chaulere musananyamule kukhazikitsa. Chilolezo choyambirira chimatsimikizika ndi malo opanga ndi msonkhano.

2. Ikani chilolezo

Amadziwikanso kuti chilolezo chokwanira, ndicho chilolezo pomwe kubereka ndi kubowola ndi kupha nyumba zakhazikitsidwa koma sizinagwire ntchito. Chilolezo chokwera ndi chocheperako kuposa chilolezo choyambirira chifukwa chophatikizira, ndikuwonjezera mphete yamkati, kuchepetsa mphete yakunja, kapena yonse.

3. Chuma pantchito

Ngati kubereka kukugwira ntchito, kutentha kwamkati kwamkati ndi kuchuluka kwa mafuta okwanira, kotero kuti kuchotsedwa kumatsika. Nthawi yomweyo, chifukwa cha mphamvu, kuwonongeka kwa zotanuka kumachitika pakati pa thupi lozungulira komanso mtunduwo, womwe umachulukitsa chilolezo. Kaya kunyamula chilolezo chonyamula katundu ndi chokulirapo kapena chocheperako kuposa chilolezo chokwera kumadalira zinthu ziwiri izi.

Zovala zina zogubuduzika sizingasinthidwe kapena kusakazidwa. Amapezeka m'mitundu isanu ndi umodzi, kuyambira 0000 mpaka 5000; Pali mitundu 6000 (yolumikizana yolumikizana) ndi lembani 1000, lembani 2000 ndi mtundu wa 3000 ndi mabowo a cue wamkati. Kukhazikitsa kwamtunduwu kwa mitundu iyi yofuula, mutatha kusintha, kudzakhala kocheperako kuposa chilolezo choyambirira. Kuphatikiza apo, zimbalangondo zina zitha kuchotsedwa, ndipo chilolezo chimatha kusintha. Pali mitundu itatu ya mavalidwe: mtundu wa 7000 (wosungunuka), lembani 8000 (mtundu wa mpira wa 8000 (wobzala) ndi mtundu wa 9000 (wosungunuka). Palibe chilolezo choyambirira m'mitundu itatu iyi yamitundu ija. Pa mtundu wa 6000 ndi mtundu wa 7000 wogubuduza, chilolezo cha radial chimachepetsedwa ndipo chivomerezo cha axial chimachepetsedwa, komanso mosemphana ndi mitundu 8000 ndi mtundu wa axial 9000 ndi njira yofunikira.

Chilolezo choyenera chimathandizanso kugwira ntchito yobowola. Chilolezocho ndi chochepa kwambiri, kutentha kozungulira kumakwera, kulephera kugwira ntchito mwachizolowezi, kotero kuti thupi logwedeza limakhazikika; Chilolezo chochuluka kwambiri, kugwedezeka kwa zida, kugudubuza phokoso.

Njira ya radial Clearance ikuyendera motere:

I. Njira Yomvera

1. Ndi dzanja la dzanja, zonyamula ziyenera kukhala zosalala komanso zosinthika popanda kumamatira komanso kukhazikika.

2. Gwedezani mphete yakunja ya kuyanjana ndi dzanja. Ngakhale chilolezo cha radial chili ndi 0.01mm, kayendedwe kakang'ono kwa zonyamula ndi 0.10-0.15mm. Njirayi imagwiritsidwa ntchito pamtunda umodzi wa mzere wa centripetathal.

Njira Yoyeza

1. Chongani ndikutsimikizira gawo lalikulu lokhala ndi chilema, ikani chilema pakati pa thupi la 10 ndi lakunja, ndipo makulidwe oyenera ndi chilolezo cha kubereka. Njirayi imagwiritsidwa ntchito kwambiri pamayanjano odziyimira komanso ozungulira cylindrical.

2, onani ndi chizindikiritso choyimba, choyamba khazikitsani chizindikiro choyimbira kuti zire zero, kenako kwezani mphete yakunja, kuwerenga kwa dial ndi chilolezo chakuzirala.

Njira yoyendera ya axial chilolezo ndi motere:

1. Njira Yokongoletsera

Onani chilolezo cha mawu ozungulira ndi chala chanu. Njirayi iyenera kugwiritsidwa ntchito pomwe shaft imawululidwa. Shaft ikatsekedwa kapena sizingayang'anitsidwe ndi zala pazifukwa zina, onani ngati shaft imasinthika mosinthasintha.

2. Njira yoyezera

(1) Onani ndi chilema. Njira yogwiritsira ntchito ndi yofanana ndi yowunika radial chilolezo cholumikizira, koma axial alcrance ayenera kukhala

C = Nthambi / Tchimo (2 Beta)

Kumene c - axial chilolezo, mm;

- Makulidwe a Gauge, mm;

- Kunyamula conne ngodya, (°).

(2) Yang'anani ndi chizindikiritso choyimba. Pamene Crowbar amagwiritsidwa ntchito poyendetsa shaft yosunthika ku maudindo awiri owopsa, kusiyana kwa chisonyezo cha kuyimba ndi mawu a axial achulukitsa. Komabe, mphamvu yomwe imagwiritsidwa ntchito kwa Crowbar sayenera kukhala lalikulu kwambiri, apo ayi chipolopolo chidzakhala ndi kuphatikizika kwabwino, ngakhale kuwonongeka kwake kuli kochepa kwambiri, kumakhudza kulondola kwa chitsimikizo cha chilolezo cha axial.
