Bearing Hub, cum să înlocuiți butucul de la DAEWOO Nexia faceți-o singur

Când conduceți pe o mașină, este destul de des posibil să respectați apariția zuminiei caracteristice, care o poate suprascrie în timp. În plus, se schimbă în funcție de starea suprafeței drumului. Pe un drum bun - zumul dispare sau scade, deci poate părea că nu este nevoie să se repare, dar de îndată ce roțile merg la un drum rău - zumul apare din nou. În plus, la viteză mare, puteți auzi un anumit embosat. Motivul pentru apariția acestor simptome, de regulă, este defecțiunea purtării butucului. Este demn de remarcat faptul că, dacă nu înlocuiți o poartă în timp util, atunci când conduceți să se blocheze, care este extrem de periculos și reprezintă o amenințare la adresa vieții, prin urmare, cu cele mai mici manifestări ale simptomelor defecțiunilor descrise mai sus, Ar trebui înlocuit de lagărul de hub cât mai curând posibil. Despre acest lucru mai departe în articol.

Bearing Hub, ce sarcini efectuează

Rulmentul este un mecanism care susține o parte a sprijinului. Este capabil să mențină arborele, axa sau orice alt element, dar în orice caz, scopul său principal este fixarea arborelui în spațiu, care asigură distribuția sau rotirea sa liberă. A doua funcție a rulmentului hub este percepția sarcinii mecanice, precum și transferul acestuia către alte elemente.

Rulmentul butucului este un mecanism care este un rulment de rulare. Oferă o rotație netedă a roții din jurul axei. Aceste rulmenți sunt rânduri și dublu rând, precum și tipul deschis și închis. Acestea sunt folosite la pasageri și camioane. Rulmenții de roți pentru roțile din față și din spate diferă semnificativ una de cealaltă.

Rulmenții cu butuc de mașini sunt supuși în mod constant la sarcini extreme. Includerea diferențelor de temperatură ridicată, impactul asupra mediului, formarea de șocuri la intrarea în gropi, direcția, frânele, unitatea. Este demn de remarcat faptul că reacția nu trebuie să împiedice rotația roatei, care ar trebui să se rotească cu fricțiune minimă și zgomot admisibil.

Rulmenți, dispozitiv, avantaje și dezavantaje

Rulmenții cu role sunt foarte susceptibile la instalarea, care, dacă este efectuată incorect, este capabilă să elimine instantaneu partea în ordine. Newbies care nu știu despre această caracteristică a rulmenților cu role de role înșeală adesea lucrătorii lipsiți de scrupule din STO, care produc înlocuirea acestui element la mâna ambulanță și prost.

Diagonal, dispozitiv, avantaje și dezavantaje

Rulmenții diagonali sunt capabili să reziste la sarcini grele și să aibă o rezistență excelentă la uzură.

Cu toate acestea, munca lor, cum ar fi rulmenții cu role, depinde de instalarea corectă (strângere puternică), altfel vor eșua.

Momentul strângerii lagărului, ceea ce este și ca un cuplu al rulmentului afectează durata funcționării

Momentul strângerii lagărului este un eveniment care ar trebui făcut cu precizie în conformitate cu recomandările producătorului vehiculului. După cum sa menționat deja, setarea incorectă a rulmentului implică defalcarea sa.

Dacă mai devreme pentru ajustarea rulmentului necesită abilități speciale, precum și prezența unor instrumente speciale care au fost greu de găsit la acel moment, atunci astăzi nu există probleme în această privință. Acum, fiecare proprietar de mașini poate cumpăra un set de instrumente necesare și poate obține date care vă permit să controlați independent starea de lagăre și alte elemente de mașină.

Rulmentul de hub este defect, semne de rupere

Principalele semne ale defecțiunii lagărului mașinii sunt:

  1. Un zgomot puternic sau zgomot care se aude din spatele vehiculului. Dacă butucul de rulare este defect, zgomotul devine mai mult când întoarceți întoarcerea.
  2. Aspectul reacției din roata din spate, care este însoțită de zgomot sau de atingere.

Instrumente și corpuri de completare pentru înlocuirea lagărului, siguranța

  1. Un tractor special.
  2. Ciocan.
  3. Clește pentru a dezmembra o inele de oprire.
  4. Cheie pe 17.
  5. Un hexagon cheie pe 10.
  6. Şurubelniţă.
  7. Daltă.

Înainte de înlocuire, nu uitați să puneți barele anti-tartare sub roțile din spate și sub corp - focalizați.

  8. Cu o șurubelniță, scoatem clema și cu ajutorul unei daltă, bateți cu grijă inelul interior de pe axă.
  9. Vom prescrie un nou purtând cu ajutorul unui climat vechi.
  10. După asamblare, tragem piulița, aplicând un anumit efort.

După operație, ar trebui să conducă trei sau patru zile. Apoi trebuie să trageți din nou piulița pentru a elimina reacția.

Sfaturi Profi, cum să faceți un loc de muncă în mod corespunzător, care lubrifiant este mai bine de utilizat pentru rulment

  1. Este de dorit să se înlocuiască lagărele pe roțile din spate sau din față, indiferent dacă valoarea este partea de acolo.
  2. Alegeți lubrifiantul corect sub rulmenții.
  3. Este imposibil să bateți ciocanul drept pe rulment, este necesar să o faceți cu o tabletă din lemn.
  4. În nodurile Hub este imposibil să punem un decalaj, deoarece la fabrică au fost colectate ținând cont de lacunele.
  5. Când înlocuiți rulmentul, asigurați-vă că verificați starea axei și a carcasei.
  6. Nu puteți regla sau muta garnitura de pe nodurile roților.
