Kufananiza ma bearings ogubuduza ndi mabere omveka

Za ntchitomayendedwe, katundu mkangano wa mayendedwe okwera akhoza kugawidwa mu mayendedwe kugubuduza ndi kutsetsereka mayendedwe, tikhoza kusankha mitundu yosiyanasiyana yonyamula malinga ndi zofunika zenizeni za ntchito, kugubuduza fani ndi kutsetsereka ndi makhalidwe osiyana ntchito,

Mfundo zazikuluzikulu zakugudubuza mayendedwendi:

1. Small kukangana damping (zogwirizana ndi sanali madzi kukangana kutsetsereka kutsetsereka), kusintha koyambira;

2. Ikhoza kunyamula katundu wa radial ndi axial panthawi imodzimodzi, kufewetsa dongosolo lothandizira;

3. Chilolezo cha radial ndi chaching'ono, ndipo chilolezocho chingathenso kuthetsedwa ndi njira yobweretsera, kotero kuti kulondola kozungulira kumakhala kwakukulu;

4. Kusinthana kwabwino komanso kukonza kosavuta.

 

Mfundo zazikuluzikulu zazimbalangondondi:

1. Ntchito yokhazikika komanso yopanda phokoso;

2. Kulondola kozungulira kwakukulu;

3. Small kukangana imfa pa madzi kondomu;

4. Kukula kwa radial yaying'ono;

5. Kulemera kwakukulu.

 

Kodi ubwino ndi kuipa kotani kwa ma bearings odzigudubuza poyerekezera ndi ma faniko opanda kanthu? Kusanthula kuli motere:

 

Poyerekeza ndi zimbalangondo zowoneka bwino, zogudubuza zili ndi zabwino izi:

1. Kuthamanga kwapakati kwa ma bearings ogubuduza ndi kakang'ono kuposa kamene kamayenda, ndipo mphamvu yotumizira ndi yokwera kwambiri. Nthawi zambiri, mikangano ya ma bearings otsetsereka ndi 0.08-0.12, pomwe kugundana kwa ma bearings ndi 0.001-0.005;

2. Mapiritsi opukutira adakhala okhazikika, osasinthika komanso okhazikika, oyenera kupanga ndikupereka zambiri, ndipo ndiosavuta kugwiritsa ntchito ndikusunga;

3. Mapiritsi ogubuduza amapangidwa ndi zitsulo zokhala ndi zitsulo ndipo amapatsidwa chithandizo cha kutentha, kotero kuti zitsulo zogudubuza sizingokhala ndi zida zapamwamba zamakina ndi moyo wautali wautumiki, komanso zimatha kupulumutsa zitsulo zamtengo wapatali zopanda chitsulo zomwe zimagwiritsidwa ntchito popanga zitsulo zoyendetsa;

4. Chilolezo chamkati cha kugubuduza ndi chaching'ono kwambiri, ndipo kulondola kwa makina a gawo lililonse ndikwapamwamba, kotero kuti kuthamanga kwachangu kumakhala kwakukulu. Panthawi imodzimodziyo, kukhwima kwa kubereka kungawonjezedwe ndi preloading. Izi ndizofunikira kwambiri pamakina olondola;

5. Ma bere ena ogubuduza amatha kunyamula katundu wa radial ndi axial load nthawi imodzi, kotero kuti kamangidwe kameneka kamakhala kosavuta;

6. Chifukwa cha kufalikira kwapamwamba komanso kutsika kwa kutentha kwa mayendedwe ogubuduza, kugwiritsa ntchito mafuta opaka mafuta kumatha kuchepetsedwa, ndipo kudzoza ndi kukonza kumakhala kosavuta;

7. Mapiritsi ogudubuza angagwiritsidwe ntchito mosavuta ku uranium kumbali iliyonse ya danga.

 

 

Komabe, zonse zimagawidwa pawiri, ndipo mayendedwe ogubuduza amakhalanso ndi zovuta zina, zazikulu ndi izi:

1. Katundu wonyamula katundu wa mayendedwe ogubuduza ndi ochepa kwambiri kuposa a mayendedwe otsetsereka a voliyumu yomweyi, motero, kukula kwa radial kwa mayendedwe ogubuduza ndi akulu. Chifukwa chake, munthawi yonyamula katundu wambiri komanso nthawi yomwe imafunikira kukula kwa radial yaying'ono ndi mawonekedwe ophatikizika (monga injini yoyaka mkati mwa crankshaft kunyamula), mayendedwe otsetsereka amagwiritsidwa ntchito kwambiri;

2. Kugwedezeka ndi phokoso la mayendedwe ogubuduza ndi aakulu, makamaka kumapeto kwa ntchito, choncho, pamene zofunikira zolondola zimakhala zapamwamba kwambiri ndipo kugwedezeka sikuloledwa, mayendedwe oyendayenda ndi ovuta kukhala oyenerera, ndipo zotsatira za mayendedwe otsetsereka ndi zambiri bwino;

3. Mapiritsi ogubuduza amakhala okhudzidwa kwambiri ndi matupi akunja monga zitsulo zachitsulo, ndipo zinthu zakunja zikalowa m'chifanizirocho, zidzatulutsa kugwedezeka kwakukulu kwapakatikati ndi phokoso, zomwe zidzayambitsanso kuwonongeka koyambirira. Kuphatikiza apo, mayendedwe ogubuduza amathanso kuwonongeka koyambirira chifukwa cha zitsulo zophatikizika. Ngakhale kuwonongeka koyambirira sikunachitike, pali malire pa moyo wa ma bearings ogubuduza. Mwachidule, mayendedwe ogubuduza amakhala ndi moyo wamfupi wautumiki kuposa ma fani wamba.

 

Poyerekeza ndi kugubuduza fani ndi kutsetsereka mayendedwe, aliyense ali ubwino wake ndi kuipa, ndipo aliyense occupies zina ntchito nthawi, Choncho, awiri sangathe kwathunthu m'malo wina ndi mzake, ndipo aliyense akufotokozera mu njira inayake ndi kumawonjezera munda wake. Komabe, chifukwa cha zabwino zomwe zimagubuduza ma bearings, pali chizolowezi choti ochedwa apambane. Pakalipano, mayendedwe ogubuduza apangidwa kukhala mtundu waukulu wothandizira wa makina, ndipo amagwiritsidwa ntchito kwambiri.
