Kodi chilolezo ndi chiyani ndipo chilolezo chimayesedwa bwanji kwa ma bearings ogubuduza?

Chilolezo cha kugubuduza ndi kuchuluka kwa ntchito yomwe imagwira mphete imodzi m'malo mwake ndi ina mozungulira ma radial kapena axial. Ntchito yayikulu motsatira njira ya radial imatchedwa chilolezo cha radial, ndipo ntchito yayikulu motsatira njira ya axial imatchedwa axial clearance. Nthawi zambiri, chiwongola dzanja chokulirapo, chiwongolero chachikulu cha axial, ndi mosemphanitsa. Malingana ndi momwe chiberekero chimakhalira, chilolezo chikhoza kugawidwa m'magulu atatu awa:

I. Chilolezo choyambirira

Free chilolezo pamaso kubala unsembe. Chilolezo choyambirira chimatsimikiziridwa ndi kukonza ndi kusonkhana kwa wopanga.

2. Kukhazikitsa chilolezo

Zomwe zimadziwikanso kuti chilolezo choyenerera, ndi chilolezo pamene chotengera ndi shaft ndi nyumba zonyamula zida zakhazikitsidwa koma sizikugwira ntchito. Chilolezo chokwera ndi chaching'ono kusiyana ndi chilolezo choyambirira chifukwa cha kusokoneza, kuwonjezera mphete yamkati, kuchepetsa mphete yakunja, kapena zonse ziwiri.

3. Chilolezo cha ntchito

Pamene kubereka kumagwira ntchito, kutentha kwa mphete yamkati kumakwera kwambiri ndipo kuwonjezereka kwa kutentha kumafika pamtunda, kotero kuti chilolezo chonyamula chimachepetsa. Panthawi imodzimodziyo, chifukwa cha mphamvu ya katundu, kusinthika kwa zotanuka kumachitika pamalo olumikizana pakati pa thupi logudubuza ndi msewu wothamanga, zomwe zimawonjezera chilolezo. Kaya chilolezo chogwira ntchito ndi chachikulu kapena chaching'ono kuposa chilolezo chokwera chimadalira kuphatikizika kwazinthu ziwirizi.

Zina zogudubuza sizingasinthidwe kapena kupasuka. Amapezeka mumitundu isanu ndi umodzi, kuyambira 0000 mpaka 5000; Pali mtundu wa 6000 (makona olumikizirana) ndi mtundu 1000, Type 2000 ndi Type 3000 okhala ndi mabowo a cone mu mphete yamkati. Chilolezo chokwera cha mitundu iyi ya mayendedwe ogubuduza, mutatha kusintha, chidzakhala chocheperako kuposa chilolezo choyambirira. Kuphatikiza apo, mayendedwe ena amatha kuchotsedwa, ndipo chilolezocho chikhoza kusinthidwa. Pali mitundu itatu ya mayendedwe: Type 7000 (tapered roller bear), mtundu 8000 (kutulutsa mpira) ndi mtundu 9000 (kutulutsa kozungulira). Palibe chilolezo choyambirira mu mitundu itatu iyi ya mayendedwe. Kwa mtundu wa 6000 ndi mtundu wa 7000 wogubuduza mayendedwe, chilolezo cha radial chimachepetsedwa ndipo chilolezo cha axial chimachepetsedwa, ndipo mosemphanitsa, pamene mtundu wa 8000 ndi mtundu wa 9000 wogudubuza, chilolezo cha axial chokha ndichofunika kwambiri.

Chilolezo choyikira bwino chimathandizira kugwira ntchito kwanthawi zonse kwa cholumikizira. Chilolezocho ndi chaching'ono kwambiri, kutentha kwa kutentha kumakwera, sikungathe kugwira ntchito bwino, kotero kuti thupi lozungulira limakhala lokhazikika; Chilolezo chochuluka, kugwedezeka kwa zida, phokoso lozungulira.

Njira yowunikira ma radial clearance ndi motere:

I. Njira yachidziwitso

1. Ndi dzanja lozungulira lozungulira, kunyamula kuyenera kukhala kosalala komanso kosinthika popanda kumamatira ndi astringency.

2. Gwirani mphete yakunja ndi dzanja. Ngakhale chilolezo cha radial ndi 0.01mm kokha, kayendedwe ka axial pamwamba pa chigawocho ndi 0.10-0.15mm. Njirayi imagwiritsidwa ntchito pamzere umodzi wa mpira wapakati.

Njira yoyezera

1. Yang'anani ndi kutsimikizira malo olemera kwambiri a katundu wogubuduza ndi phokoso, ikani chomverera pakati pa thupi lozungulira 180 ° ndi mphete yakunja (yamkati), ndipo makulidwe oyenera a chomverera ndi chilolezo cha radial chonyamula. Njirayi imagwiritsidwa ntchito kwambiri pazinyalala zodziyimira pawokha komanso mayendedwe odzigudubuza a cylindrical.

2, yang'anani ndi chizindikiro choyimba, choyamba ikani chizindikiro choyimba kuti chikhale zero, kenako kwezani mphete yozungulira yakunja, chowerengera choyimba ndichochilolezo cha radial.

Njira yowunikira axial clearance ndi motere:

1. Njira zomverera

Yang'anani chilolezo cha axial cha kugudubuza ndi chala chanu. Njirayi iyenera kugwiritsidwa ntchito pamene mapeto a shaft awonekera. Pamene mapeto a shaft atsekedwa kapena sangathe kufufuzidwa ndi zala pazifukwa zina, yang'anani ngati shaft imasinthasintha mozungulira.

2. Njira yoyezera

(1) Fufuzani ndi chomverera. Njira yogwiritsira ntchito ndi yofanana ndi yoyang'ana chilolezo cha radial ndi feeler, koma chilolezo cha axial chiyenera kukhala.

C = lambda/sin (2 beta)

Kumene c -- axial chilolezo, mm;

-- makulidwe a geji, mm;

-- Bearing cone angle, (°).

(2) Yang'anani ndi chizindikiro choyimba. Pamene crowbar imagwiritsidwa ntchito kuwongolera shaft yosuntha kupita kumalo awiri ovuta kwambiri, kusiyana kwa kuwerenga kwa chizindikiro cha dial ndiko kuvomerezeka kwa axial kwa mayendedwe. Komabe, mphamvu yomwe imagwiritsidwa ntchito pa crowbar siyenera kukhala yayikulu kwambiri, apo ayi chipolopolocho chidzakhala ndi mapindikidwe otanuka, ngakhale mapindikidwewo ndi ochepa kwambiri, zidzakhudza kulondola kwa chilolezo cha axial.
