Zinthu zingapo zomwe zimakhudza kutentha kwa ntchito ya chogwirira

 

Pambuyo poti chogwiriracho chapanikizidwa muchogwirira, iyenera kuzungulira mosinthasintha popanda kumva ngati yatsekeka. Ngati pali kusinthasintha kwakukulu pakuzungulira, zikutanthauza kuti kukula kwa shaft ndi kwakukulu kwambiri ndipo kulekerera kuyenera kuchepetsedwa. Ngati kukanikizachogwirira chozungulira chozunguliraikakanikizidwa mu shaft ndikuzunguliridwa ndi dzanja ndi kumverera koonekeratu kwa "phokoso", mwina kulekerera kwa shaft ndi kwakukulu kwambiri kapena kuzungulira kwa shaft sikwabwino. Chifukwa chake, polamulira kulekerera kwa shaft ndi chipinda chonyamula, ndikofunikiranso kuwongolera kuzungulira, pakadali pano, opanga ambiri am'nyumba amangolamulira kulekerera, koma osati kuzungulira.

ChifukwachogwiriraNdi chinthu cholondola kwambiri, ngati sichinasonkhanitsidwe bwino, n'zosavuta kuwononga mbewa yonyamulira ndikuwononga bearing. Ma bearing a cylindrical roller ayenera kukhala ndi nkhungu yapadera akamasonkhana, sangagwedezedwe nthawi iliyonse, pamene kukanikiza mu shaft kungangokakamizidwa mu bwalo laling'ono, ndipo bwalo lalikulu lokha ndi lomwe lingalimbikitsidwe mukakanikiza bwalo lalikulu. Kusonkhanako kumafuna kugwiritsa ntchito pneumatic kapena hydraulic, ndipo ma dies apamwamba ndi apansi ayenera kukhala kunja kwa malo opingasa akamakanikiza, ngati pali kupendekera, ngalande yonyamulira idzawonongeka chifukwa cha mphamvu, ndipo bearing idzapanga phokoso.

1. Kodi chiyenera kuchitika chiyani pamenechogwirirakutentha kumakwera:

Kutentha kwa bearing kukakwera, choyamba dziwani ngati sikukugwira ntchito bwino, ngati kukakwera, chithandizo chotsatirachi chiyenera kuchitidwa:

(1). Onani ngati mafuta ali mu muyezo wa mafuta ndi abwinobwino, ngati si abwinobwino, onani ngati valavu yotulutsira mafuta ya thanki ya mafuta yatsekedwa. Ngati yatsekedwa bwino, mafuta ayenera kuwonjezeredwa, ndipo ngati gasket yotsekera mafuta ikutuluka, iyenera kutsekedwa.

(2). Tengani chitsanzo cha mafuta kuti muwone ngati mtundu wa mafutawo ukusintha, ndikuchita mayeso a labotale kuti muwone ngati wawonongeka. Ngati kuwonongeka kwatsimikizika, makinawo ayenera kuyimitsidwa ndikusinthidwa ndi mafuta atsopano.

(3). Yang'anani ngati bearing ili ndi phokoso losazolowereka, ndipo dziwani ngati bearing swing si yozolowereka.

(4). Kuthamanga kwa mafuta kwa gavana kuyenera kuyesedwa, ngati kuthamanga kwa mafuta kuli kochepa, kungayambitse valavu yamadzi ozizira kutseka.

(5). Yang'anani ngati kuthamanga kwa madzi ozizira, kuyenda kwa madzi, ndi njira ya mapaipi ndi zabwinobwino. Ngati kuthamanga kwa madzi kuli kochepa, mwina fyuluta yatsekedwa, ndipo ngati singachiritsidwe pa nthawi yake, ikhoza kuyimitsidwa kuti ichiritsidwe, ndipo ikatsimikizika kuti ingagwire ntchito, ikhoza kugwiritsidwanso ntchito.

2. Choyamba, tiyeni tiwone zifukwa zomwe zimapangitsa kuti kutentha kwa bearing kukwere:

(1). Zingakhale kuwonongeka kwa mtundu wa mafuta a bearing, mafuta okhawo sali oyera kapena mafutawo amawonongeka panthawi yogwira ntchito, monga kuwonjezeka kwa chinyezi mu mafuta kudzapangitsa kuti asidi a mafutawo achuluke, zomwe zimachepetsa mphamvu ya mafuta odzola, kotero kuti bearing pad imaphwanyika, zomwe zimapangitsa kuti kutentha kwa bearing kukwere.

(2). Zingachitike chifukwa cha kusokonezeka kwa madzi ozizira a bearing.
