Ulalo wogwirizira kuti chiwombankhangacho sichingasiyane kwenikweni ndi pamene chikugwira ntchito ndikusintha kwamafuta, chifukwa ngati gawo la pulley la slewing likugwira ntchito bwino, liyenera kukonzedwa ndi thermally poyamba, kuti lisunge bwino magwiridwe antchito anthawi zonse. kupha.Kupatula apo, kubera Kukagwiritsidwa ntchito, gawo la pulley ndi gawo lofunikira lomwe limatha kunyamula zinthu zonse moyenera, chifukwa chake tiyenera kulabadira zinthu zambiri pochita ndi ulalo wowotchera, ndiye lero tili pano kuti tichite. ulalo wowotchera wowotchera wowotcha.Zolemba zikufotokozedwa mwatsatanetsatane.
Nthawi zambiri, pamene ng'anjo ikuwotcha, njira zoyenera zogwirira ntchito ziyenera kuchitidwa poyamba.

Njira zodziwika bwino ndi izi: kufota→kukalipa→kuzizimitsa ndi kutenthetsa →kumaliza→njira yozimitsa lawi lamoto →kugaya pamwamba ndi zina.Chimodzi mwa malo othamanga ndi moto wozimitsidwa kupanga gulu lofewa.Zomwe zimatchedwa lamba wofewa ndi malo omwe sanatenthedwe kutentha.Mapangidwe a lamba ofewa ndi ofunikira kuti azitha kutentha.M'machitidwe omaliza ochizira kutentha, popeza kutalika kwa bwalo lamsewu wowombera ndi wokulirapo, kuzimitsa moto kumagwiritsidwa ntchito.Njirayi ndikugwiritsa ntchito acetylene kutentha pamwamba pa workpiece kuti ikhale yolimba ndikuwonjezera madzi.Kuzizira, ndondomekoyi ikuchitika mosalekeza.Mfuti yamoto yoyaka moto ndi mfuti yamadzi imayikidwa palimodzi pamene ikupanga kuzungulira mozungulira bwalo la workpiece.M'machitidwe omaliza ochizira kutentha, popeza kutalika kwa bwalo lamsewu wowombera ndi wokulirapo, kuzimitsa moto kumagwiritsidwa ntchito.Njirayi ndikugwiritsa ntchito acetylene kutenthetsa pamwamba pa workpiece kuti ikhale yolimba ndikuwonjezera madzi kuti ikhale yozizira.Mfuti yamoto yotentha yamoto ndi mfuti yamadzi imayikidwa palimodzi pamene ikupanga kuyendayenda mozungulira mozungulira bwalo la workpiece.

Pamene kusuntha kuli pafupi ndi madigiri a 360, kutentha ndi kupopera madzi kumayimitsidwa nthawi yomweyo.Ndiko kuti, madera ozungulira otenthetsera ndi kupopera madzi samadutsana.Ming'alu mu workpiece ikhoza kuchitika ngati malo ozungulira omwe kutentha ndi kutsitsi kwa madzi kumachitika (mankhwala otentha pamakona apamwamba kuposa madigiri 360 pa bwalo).Kutalika kwa tangential kwa malo osatenthedwa nthawi zambiri kumakhala 15 mm.Dera la 15mm ili limatchedwa lamba wofewa mu mphete yophera.Mu Chingerezi, nthawi zambiri imakhala SOFT ZONE.Muzochitika zachilendo, khalidwe lachitsulo "S" limayimiridwa pa malo omwe lamba wofewa alipo mu workpiece kuti asonyeze malo enieni a lamba ofewa.Zogulitsa kunja kapena zapakhomo nthawi zambiri zimakhala ndi chizindikiro chofunikira kwambiri ichi.

Pazodziwikiratu zoyenera pakuwotcha pakugwira ntchito yotentha, izi ndizofanana ndi zoyambira zomwe takupangani pamwambapa, chifukwa chake tiyenera kulabadira ndikuzimvera chimodzimodzi.Choncho, ntchito yolondola ya gawo la pulley ya kupha anthu imatsimikiziridwa bwino.
