momwe mungasankhire kukula kwa unyolo wozungulira

Ma roller chain ndi chinthu chofunikira kwambiri m'mafakitale osiyanasiyana monga makina, magalimoto ndi ulimi. Ma roller chain amenewa amapangidwira kuti azitha kugwiritsa ntchito mphamvu zamakanika bwino, zomwe zimapangitsa kuti akhale gawo lofunika kwambiri pa ntchito zambiri. Komabe, kusankha kukula koyenera kwa roller chain nthawi zambiri kumakhala kovuta, makamaka kwa omwe angoyamba kumene ntchito. Buku lotsogolerali likufuna kufotokoza momveka bwino momwe zinthu zilili komanso kuti ogwiritsa ntchito azitha kudziwa kukula koyenera kwa roller chain malinga ndi zosowa zawo.

Dziwani zambiri za kukula kwa unyolo wozungulira:

Tisanaphunzire zovuta posankha kukula koyenera kwa unyolo wozungulira, tiyeni tidziwe bwino njira yomwe imagwiritsidwa ntchito pofotokoza kukula kwake. Unyolo wozungulira umadziwika ndi mtunda wake, womwe umayimira mtunda pakati pa malo awiri ozungulira omwe ali pafupi. Kuzungulira kumawonetsedwa mu mainchesi kapena mayunitsi a metric (mwachitsanzo, mainchesi 0.375 kapena mamilimita 9.525).

Gawo 1: Dziwani zofunikira zanu:

Kuti mudziwe kukula koyenera kwa unyolo wozungulira, ndikofunikira kuwunika zofunikira pa ntchito inayake. Ganizirani zinthu zotsatirazi:

1. Kutumiza Mphamvu: Imawerengera mphamvu zomwe zimafunika pa dongosololi mu mayunitsi a mphamvu ya akavalo (HP) kapena kilowatts (kW). Dziwani mphamvu yochuluka yomwe imatulutsa komanso momwe mphamvuyo ingathere.

2. Liwiro: Dziwani liwiro lozungulira (RPM) la sprocket yoyendetsa ndi sprocket yoyendetsedwa. Ganizirani liwiro logwirira ntchito lomwe mukufuna komanso kusinthasintha kulikonse kwa liwiro komwe kungachitike.

3. Zinthu zokhudzana ndi chilengedwe: Ganizirani momwe zinthu zimagwirira ntchito monga kutentha, chinyezi, fumbi, kapena zinthu zina zilizonse zowononga zomwe zingakhalepo.

Gawo 2: Werengani kutalika kwa unyolo:

Zofunikira zikatsimikizika, gawo lotsatira ndikuwerengera kutalika koyenera kwa unyolo. Izi zimatsimikiziridwa ndi mtunda pakati pa malo oyambira a sprocket yoyendetsera ndi sprocket yoyendetsedwa. Gwiritsani ntchito njira iyi:

Utali wa unyolo (pitch) = (chiwerengero cha mano pa sprocket yoyendetsa + chiwerengero cha mano pa sprocket yoyendetsa) / 2 + (mtunda wapakati / pitch)

Gawo 3: Ganizirani Zofunikira pa Mavuto:

Kukakamira koyenera ndikofunikira kwambiri pa moyo ndi magwiridwe antchito a unyolo wozungulira. Kukakamira kosakwanira kungayambitse kutsetsereka kwa unyolo, zomwe zimapangitsa kuti kuwonongeke msanga komanso kuchepetsa mphamvu yotumizira. Mosiyana ndi zimenezi, kukakamira kwambiri kungayambitse kukangana kwakukulu komanso kusweka. Funsani buku la wopanga kuti mudziwe kuchuluka kwa kukakamira komwe kukugwirizana ndi kukula kwa unyolo wanu ndi momwe mungagwiritsire ntchito.

Gawo 4: Tsimikizani kuchuluka kwa katundu:

Kulemera kwa unyolo wozungulira kumatsimikiziridwa ndi kukula kwake. Ndikofunikira kutsimikizira kuti unyolo wosankhidwayo ungathe kuthana ndi katundu woyembekezeredwa. Opanga nthawi zambiri amapereka machati a mphamvu yonyamula katundu omwe amaganizira zinthu zosiyanasiyana monga mphamvu yokoka, kukula kwa roller ndi zinthu. Sankhani unyolo wozungulira womwe umaposa zofunikira za katundu womwe mukufuna kugwiritsa ntchito kuti muwonetsetse kuti umakhala nthawi yayitali komanso wodalirika.

Kukula koyenera kwa unyolo wozungulira kumachita gawo lofunika kwambiri pakugwira ntchito bwino kwa makina otumizira mphamvu. Kukula koyenera kwa unyolo kumatha kudziwika bwino powunika mosamala mphamvu, liwiro, momwe zinthu zilili komanso zofunikira pakukakamiza. Kumbukirani kuyang'ana malangizo a wopanga ndi machati a mphamvu yonyamula katundu kuti muwonetsetse kuti makina anu akhala nthawi yayitali komanso odalirika. Mukamvetsetsa bwino momwe amagwirira ntchito, mutha kusankha motsimikiza unyolo woyenera wa roller womwe mungagwiritse ntchito, zomwe zingakuthandizeni kuti mugwire bwino ntchito komanso kuti zinthu zikuyendereni bwino.
