Ni izihe nganda zikoreshwa mu bwoko bwihariye bwa bearings?

Ibyuma by’imitako bitandukanye bikoreshwa cyane mu nganda zitandukanye bitewe n’imiterere yabyo n’itandukaniro ry’imikorere. Sobanura uburyo bikoreshwa mu buryo busanzwe hamwe n’uburyo bishyirwa mu byiciro:

1. umwobo muremure Imipira yo guterura

• moderi ntoya (nk'iziri muri 606):

Udukoresho two mu rugo two gukurura, ibyuma bito bito bikoresha moteri, ibikoresho by'ubuhanga.

• Urutonde rusanzwe (nk'ibice 6000, 6002):

Moteri y'imodoka, pompe y'amazi, ibikoresho by'amashanyarazi (imashini ikoresha amashanyarazi, icyuma gisya inguni).

• Ingero z'impeta z'imbere nini (nk'izifite 6204, 6304):

Amafeni yo mu nganda, umukandara w'imodoka ikizingos, amasanduku y'ibikoresho by'ubuhinzi

2. amapine y'imizingo afite uburebure

• moderi nto n'iziciriritse (nk'izi 30205):

Amapine y'imodoka, ibikoresho byo gutwara ibintu, imigozi y'ibikoresho by'imashini.

• Ingano za arge (nk'izi 30310):

Imashini z'ubwubatsi (uruziga rw'icyuma gicukura), umugozi munini w'icyuma gicukura amabuye y'agaciro, imashini igabanya amakamyo aremereye.

3. Ibyuma bizunguruka by'uruziga (NN/NU series)

• NN3020K (inkingi ebyiri):

Imashini ikora ibyuma, rotor yihuta cyane, ijosi ry'uruganda rukora neza.

• Urukurikirane rw'ubu:

Inkunga nini ya stator ya moteri, agasanduku k'axle yo gutwara gari ya moshi.

Amategeko y'ingenzi agenga ikwirakwizwa ry'inganda:

1. Inganda z'imodoka ‌ (zifite 43%)

Amabereyingi y'aho bigira (amabereyingi y'imizingo irekuye), amabereyingi y'umuyoboro utera amashanyarazi (amabereyingi y'umupira urekuye), amabereyingi y'isanduku (amabereyingi y'umupira ufatanye n'impande)

2. Ingufu n'inganda zikomeye

Umugozi mukuru wa turbine y'umuyaga (imigozi yigenga), icyuma gitanga ingufu z'ubushyuhe (imigozi y'imigozi ya cylindrical)

3. Ibikoresho byo mu rwego rwo hejuru

Umugozi mukuru wa moteri y'indege (amabara ya keramike), agasanduku k'imodoka gakoresha umuvuduko mwinshi (amabara ya keramike akoresha umuvuduko mwinshi).

Inama yo guhitamo: Ibyuma by’icyitegererezo kimwe bishobora gukoreshwa mu bihe bitandukanye bitewe n’ingano yabyo y’ubuziranenge (P5/P4). Urugero, imashini zikoresha ibyuma zikenera ingano y’ubuziranenge ya P4 cyangwa irenga. Ibyuma by’ingufu z’umuyaga bisaba imiterere yihariye yo kurwanya ingese n’ubuzima bw’imashini. Ku bipimo by’icyitegererezo runaka, nyamuneka reba igitabo cy’amabwiriza cya tekiniki cy’uwabikoze.

Ibisabwa by'ingenzi kugira ngo imikorere y'ubwikorezi iratandukanye cyane mu nganda zitandukanye, cyane cyane hibandwa ku bipimo nko gukora neza, umuvuduko wo kuzenguruka, ubushobozi bwo gutwara imizigo, no kwihutisha ibidukikije.

Inganda z'imodoka

1. Ibyuma bishya bitwara moteri bikoresha ingufu: Bisabwa kugira umuvuduko ntarengwa (agaciro ka dm•n ≥ 70.000 mm·r/min), ubudahangarwa n'ubushyuhe bwinshi (> 150℃), n'ubudahangarwa n'ingufu nyinshi. Ibikoresho bigomba kugira ubudahangarwa bwinshi, kandi sisitemu yo gusiga amavuta igomba guhuza n'imikorere y'imodoka.

1. Ibyuma bya moteri bisanzwe: Ibyuma bya moteri bikoresha tensioner pulley na idler pulley bearing bigomba kuba biramba cyane kandi bifite urusaku ruke kugira ngo bihuze n'ibisabwa mu gutwara neza moteri hakurikijwe uburyo bwo kubungabunga ingufu za moteri.

3. Ibyuma bipima uburebure: Ibyuma bipima uburebure bigomba kwihanganira imitwaro y’imiterere y’ikirere mu gihe byujuje ibisabwa mu buryo bworoheje kandi burambye (nk’ibirometero birenga miliyoni 1).

Ibyerekeye ikirere

1. Umupaka ntarengwa: Ubushobozi bwo kwihanganira ibyuma bya moteri bigomba kuba milimetero ≤0.005 (milimetero 5), kandi moderi za gisirikare zisaba ubuziranenge bwa mikoro 0.1.

2. Ubwihangane bukabije ku bidukikije:

• Ibyuma byo mu kirere bigomba kuba birwanya ubushyuhe buri hejuru n'ubuke (-180℃ kugeza 300℃), imirasire kandi bikagira imyuka mike ihindagurika.
• Kosora ikibazo cyo gusiga amavuta hakoreshejwe icyuma gishyushya amazi ukoresheje ibikoresho bya ceramic cyangwa amavuta ya perfluoropolyether (PFPE).

3. Kwizerwa: Amahirwe yo gutsindwa 20.000 revolutions ku munota).

Ingufu n'Inganda Zikomeye

1. Ingano y'umuyoboro mukuru wa turbine y'umuyaga:

Ibyuma bizingira ikirere byigenga bigomba kwihanganira ihindagurika rikomeye ry’umuyaga n’ibihe byo kurenga, kandi irangi rirwanya ingese rigomba kuba ryaragenewe ahantu haterwa umunyu.

Igihe cyo gushushanya ni imyaka > 20, igihe cyo kubungabunga ni imyaka ≥ 5.

2. Ibikoresho by'ingufu zishyuha/amazi:

Ibyuma binini byo gutwikira ibyuma bifite imitwaro ya radial ingana na toni amagana kandi bikoreshwa hamwe na sisitemu yo gukonjesha yo hanze kugira ngo bigenzure izamuka ry'ubushyuhe.

Ibyiciro byihariye by'icyuma (nk'icyuma cya M50) bitoranywa mu bice bifite ubushyuhe bwinshi.
