Icyuho ni iki kandi icyuho gipimwa gute ku miyoboro izunguruka?

Icyuho cy'umugozi uzunguruka ni ingano ntarengwa y'ibikorwa bifata impeta imwe mu mwanya wayo indi mu cyerekezo cya radial cyangwa axial. Igikorwa ntarengwa ku cyerekezo cya radial cyitwa radial clearance, naho igikorwa ntarengwa ku cyerekezo cya axial cyitwa axial clearance. Muri rusange, uko radial clearance iba nini, ni ko axial clearance iba nini, n'ibindi. Dukurikije imiterere y'umugozi, clearance ishobora kugabanywamo ubwoko butatu bukurikira:

I. Icyemezo cy'umwimerere

Irekurwa ry'ubuntu mbere yo gushyiraho veriti. Irekurwa ry'umwimerere rigenwa n'uburyo uwakoze imashini atunganya kandi agateranya.

2. Shyiramo aho binjirira

Nanone izwi nka fit clearance, ni impushya iyo bearing n'umugozi n'aho bashyira ferrite byashyizweho ariko bitarakora. impushya zo gushyiraho ni ntoya ugereranije n'impushya za mbere bitewe n'impushya zo gushyiraho, haba kongera impeta y'imbere, kugabanya impeta y'inyuma, cyangwa byombi.

3. Kwemererwa akazi

Iyo icyuma gifata imizigo kiri mu kazi, ubushyuhe bw'imbere bw'impeta buzamuka bukagera ku rwego rwo hejuru kandi ubushyuhe bukagera ku rwego rwo hejuru, bityo aho icyuma gifata imizigo kikagabanuka. Muri icyo gihe, bitewe n'ingaruka z'umutwaro, guhindagurika kwa elastic bibaho aho icyuma gihurira n'umuhanda, ibyo bikaba byongera aho icyuma gifata imizigo kigera. Niba aho icyuma gifata imizigo ari kinini cyangwa gito ugereranyije n'aho icyuma gifata imizigo giherereye, biterwa n'ingaruka z'ibi bintu bibiri.

Hari ibyuma bizunguruka ntibishobora guhindurwa cyangwa gusenywa. Biboneka mu buryo butandatu, kuva kuri 0000 kugeza kuri 5000; Hari ubwoko bwa 6000 (ingular contact bearings) n'ubwoko bwa 1000, Ubwoko bwa 2000 n'ubwoko bwa 3000 bifite imyobo y'inyuma mu mpande y'imbere. Aho gushyira ubwo bwoko bwa ibyuma bizunguruka, nyuma yo guhindurwa, bizaba bito ugereranije n'aho byari biherereye mbere. Byongeye kandi, hari ibyuma bizunguruka bishobora gukurwaho, kandi aho byari biherereye hashobora guhindurwa. Hari ubwoko butatu bwa ibyuma bizunguruka: Ubwoko bwa 7000 (tapered roller bearing), ubwoko bwa 8000 (thrust ball bearing) n'ubwoko bwa 9000 (thrust roller bearing). Nta hantu hari umwimerere muri ubwo bwoko butatu bwa ibyuma bizunguruka. Kuri ibyuma bizunguruka byo mu bwoko bwa 6000 n'ubwoko bwa 7000, aho radial ihagarara haragabanuka kandi aho axial ihagarara na ho haragabanuka, naho ku mpande zombi, mu gihe kuri 8000 n'ubwoko bwa 9000, aho axial ihagarara niho honyine hafite akamaro kanini.

Uburyo bwo gushyiramo neza butuma icyuma gifata neza imikorere isanzwe. Aho giparika ni hato cyane, ubushyuhe bw'icyuma gifata buriyongera, ntibikore neza, bigatuma igice gifata kigwa; Ahantu hanini cyane, ibikoresho bihinda umushyitsi, urusaku rw'icyuma gifata.

Uburyo bwo kugenzura aho imirasire inyura ni ubu bukurikira:

I. Uburyo bwo kumva

1. Iyo bearing izunguruka n'intoki, bearing igomba kuba yoroshye kandi yoroshye idafata cyangwa ngo ikomere.

2. Kungura impeta y'inyuma y'icyuma gifata icyuma n'intoki. Nubwo aho uburebure bwacyo bwaba ari 0.01mm gusa, uburebure bw'ingingo yo hejuru y'icyuma gifata icyuma ni 0.10-0.15mm. Ubu buryo bukoreshwa ku migozi y'umupira w'umurongo umwe.

Uburyo bwo gupima

1. Genzura kandi wemeze aho umutwaro ntarengwa w’icyuma gizunguruka uherereye ukoresheje icyuma gizunguruka, shyiramo icyuma gizunguruka hagati y’umubiri uzunguruka 180° n’impeta y’inyuma (y’imbere), kandi ubugari bukwiye bw’icyuma gizunguruka ni aho icyuma gizunguruka kigarukira. Ubu buryo bukoreshwa cyane mu byuma bizunguruka byigenga n’ibyuma bizunguruka bifite icyuma cy’ingufu.

2, reba ukoresheje ikimenyetso cy'imashini, banza ushyire ikimenyetso cy'imashini kuri zeru, hanyuma uzamure impeta y'inyuma y'icyuma gizunguruka, ishusho y'ikimenyetso cy'imashini ni aho icyuma giherereye.

Uburyo bwo kugenzura aho umurongo uherereye ni ubu bukurikira:

1. Uburyo bwo gukoresha ibyuma bipima

Genzura neza aho icyuma gipfundika giherereye n'urutoki rwawe. Ubu buryo bugomba gukoreshwa iyo impera y'icyuma igaragaye. Iyo impera y'icyuma ifunze cyangwa idashobora kugenzurwa n'intoki kubera izindi mpamvu, reba niba icyuma gipfundika gihindura imiterere mu gihe cyo kuzenguruka.

2. Uburyo bwo gupima

(1) Suzuma ukoresheje umusemburo. Uburyo bwo gukora ni bumwe n'ubwo kugenzura aho imirasire iherereye ukoresheje umusemburo, ariko aho imirasire iherereye hagomba kuba

C = lambda/sin (2 beta)

Aho c -- aho umurongo uhagarara, mm;

-- Ubunini bw'igipimo, mm;

-- Inguni y'urukiramende, (°).

(2) Reba ukoresheje ikimenyetso cy'imashini. Iyo icyuma gikoreshwa mu kujyana umugozi wimuka mu myanya ibiri ikomeye cyane, itandukaniro ry'uburyo ikimenyetso cy'imashini gisomwa ni aho icyuma giherereye. Ariko, imbaraga zikoreshwa kuri icyuma gishyirwa ku mugozi ntizigomba kuba nini cyane, bitabaye ibyo icyuma kizagira imiterere ya elastic, nubwo imiterere yacyo yaba ari nto cyane, bizagira ingaruka ku buryo imiterere yacyo yapimwe.
