Ma shafts athu amagalimoto ali ndi mawonekedwe amphamvu kwambiri, zofunika kulondola kwambiri, kukana kuvala bwino, kukana kwa dzimbiri komanso magwiridwe antchito abwino kuti zitsimikizire kugwira ntchito ndi moyo wantchito wagalimoto.
Kupanga kwa shaft yosakaniza shaft kumafunika kuwongolera mosamalitsa zofunikira za zida, ukadaulo wokonza ndi mtundu wake kuti zitsimikizire kuti mawonekedwe ndi magwiridwe antchito a shaft amakwaniritsa zofunikira pakugwiritsa ntchito. Nthawi zambiri ganizirani mbali zotsatirazi:
1. Kusankha kwazinthu: Shaft yamoto nthawi zambiri imapangidwa ndi chitsulo champhamvu kwambiri kapena chitsulo chosapanga dzimbiri. Kusankhidwa kwa zinthu kumafunika kutsimikiziridwa molingana ndi zinthu monga chilengedwe chomwe chosakanizacho chimagwiritsidwa ntchito, katundu, ndi kukula kwa shaft.
2. Ukadaulo wokonza shaft: Ukadaulo wowongolera shaft yamoto nthawi zambiri umaphatikizapo maulalo angapo monga kutembenuza, kugaya, ndi kubowola. Maulalo awa amayenera kuwongolera mosamalitsa kulondola kwa makina kuti atsimikizire kuti m'mimba mwake, kutalika, kuzungulira ndi miyeso ina ya shaft ikukwaniritsa zofunikira.
3. Chithandizo chapamwamba: Kuti muwongolere mawonekedwe apamwamba komanso moyo wautumiki wa shaft yamoto, chithandizo chapamwamba chimafunikira nthawi zambiri. Mwachitsanzo, sandblasting, polishing, electroplating ndi njira zina zingagwiritsidwe ntchito pochiza pamwamba pa shaft.
4. Kusonkhana ndi kuyang'anitsitsa: Pambuyo pa kupanga shaft kutsirizidwa, kusonkhana ndi kuyang'anitsitsa kumafunikanso. Posonkhanitsa, chidwi chiyenera kuperekedwa ku malo ndi kukwanira kwa shaft kuonetsetsa kuti shaft ikhoza kuikidwa bwino mu chosakaniza. Pakuwunika, ndikofunikira kuyang'ana miyeso, kuuma, ndi kuthamanga kwa axial kuti muwonetsetse kuti shaft ikukwaniritsa zofunikira.
