Anthu akamakambirana za njinga zamoto zamawiro atatu ndi magalimoto ang'onoang'ono ang'onoang'ono ndi ma vani, nthawi zambiri amanena kuti ekseli iyi ikuyandama, ndipo ekseliyo imayandama pang'ono. "Kuyandama kwathunthu" ndi "semi-float" akutanthauza chiyani apa? Tiyeni tiyankhe funso ili pansipa.
Zomwe zimatchedwa "zoyandama zonse" ndi "zoyandama" zimatanthawuza mtundu wa kukwera kwa ma axle shafts agalimoto. Monga tonse tikudziwa, theka la shaft ndi shaft yolimba yomwe imatumiza torque pakati pa mawilo osiyanitsidwa ndi ma drive. Mbali yake yamkati imalumikizidwa ndi giya lam'mbali kudzera pa spline, ndipo mbali yakunja imalumikizidwa ndi likulu la gudumu loyendetsa ndi flange. Popeza theka la shaft liyenera kunyamula torque yayikulu kwambiri, mphamvu yake imafunika kukhala yokwera kwambiri. Nthawi zambiri, chitsulo cha alloy monga 40Cr, 40CrMo kapena 40MnB chimagwiritsidwa ntchito pozimitsa ndi kutentha komanso kuzimitsa pafupipafupi. Pogaya, pachimake chimakhala cholimba bwino, chimatha kupirira torque yayikulu, ndipo imatha kupirira katundu wina, womwe ungakwaniritse zosowa zamagalimoto pansi pamikhalidwe yosiyanasiyana.
Malinga ndi mitundu yosiyanasiyana yothandizira ya theka la shaft, theka la shafts limagawidwa m'mitundu iwiri: "yoyandama yonse" ndi "yoyandama". Ekiselo yoyandama ndi theka-yoyandama nthawi zambiri timatchula za mtundu wa shaft. "Float" apa akutanthauza katundu wopindika pambuyo pochotsedwa tsinde.
Zomwe zimatchedwa kuti shaft yoyandama yodzaza zimatanthawuza kuti theka la shaft limangokhala ndi torque ndipo silikhala ndi mphindi yopindika. Mbali yamkati ya shaft ya theka yotereyi imalumikizidwa ndi zida zam'mbali zosiyanitsira kudzera mu splines, ndipo mbali yakunja ili ndi mbale ya flange, yomwe imayikidwa ndi gudumu ndi mabawuti, ndipo gudumu limayikidwa pa chitsulocho kudzera pa ma roller awiri. mayendedwe. Mwanjira imeneyi, kugwedezeka kosiyanasiyana ndi kugwedezeka kwa mawilo, komanso kulemera kwa galimotoyo, kumapatsirana kuchokera kumawilo kupita ku ma hubs kenako kupita ku ma axles, omwe pamapeto pake amanyamulidwa ndi ma axle housings. Ma axle shafts amangotumiza torque kuchokera kumitundu kupita ku mawilo kuti ayendetse galimoto. Pochita izi, malekezero onse a theka la shaft amangonyamula torque popanda mphindi yopindika, chifukwa chake amatchedwa "yoyandama yonse". Chithunzi chotsatirachi chikuwonetsa mapangidwe ndi kukhazikitsa kwa shaft yoyandama yagalimoto. Mawonekedwe ake amapangidwira ndikuti gudumu la magudumu limayikidwa pa axle kupyolera muzitsulo ziwiri za tapered tapered, gudumu limayikidwa pa gudumu, mphamvu yothandizira imaperekedwa mwachindunji ku chitsulo, ndipo theka la shaft limadutsa. Zomangira zisanu ndi zitatu zimamangiriridwa ku hub ndikutumiza torque ku hub, ndikuyendetsa gudumu kuti litembenuke.
Theka yoyandama yodzaza ndi yosavuta kusokoneza ndikuyikanso m'malo, ndipo theka la shaft limatha kuchotsedwa pokhapokha pochotsa ma bolts okhazikika pa mbale ya flange ya theka shaft. Komabe, kulemera konse kwa galimotoyo pambuyo pochotsa theka-axle kumathandizidwa ndi nyumba ya axle, ndipo ikhoza kuyimitsidwa pansi modalirika; kuipa kwake ndikuti kapangidwe kake kamakhala kovutirapo ndipo mawonekedwe ake ndi akulu. Ndiwo mtundu womwe umagwiritsidwa ntchito kwambiri pamagalimoto, ndipo magalimoto opepuka, apakatikati komanso olemera kwambiri, magalimoto apanjira ndi magalimoto onyamula anthu amagwiritsa ntchito mtundu uwu wa axle shaft.
Zomwe zimatchedwa theka-yoyandama theka shaft zikutanthauza kuti theka la shaft silimangonyamula torque, komanso limanyamula mphindi yopindika. Mbali yamkati ya shaft yotereyi imalumikizidwa ndi mbali ya mbali yosiyana kudzera mu splines, mapeto akunja a shaft ya axle amathandizidwa ndi nyumba ya axle kudzera muzitsulo, ndipo gudumu limayikidwa pa cantilever kumapeto kwa kunja kwa chigawocho. chingwe cha axle. Mwanjira imeneyi, mphamvu zosiyanasiyana zomwe zimagwira pa mawilo ndi nthawi yopindika zomwe zimatsatiridwa zimaperekedwa mwachindunji kumitengo ya theka, ndiyeno kupita ku mayendedwe a mayendedwe. Pamene galimoto ikuthamanga, theka la shafts silimangoyendetsa magudumu kuti azungulira, komanso amayendetsa magudumu kuti azizungulira. Kuthandizira kulemera kwathunthu kwa galimotoyo. Kumapeto kwamkati kwa theka la shaft kumangokhala ndi torque koma osati mphindi yopindika, pomwe kumapeto kwakunja kumakhala ndi torque komanso mphindi yopindika, motero amatchedwa "semi-floating". Chithunzi chotsatirachi chikuwonetsa kapangidwe ndi kuyika kwa semi-axle yoyandama yagalimoto. Maonekedwe ake apangidwe ndi chakuti mapeto akunja amakhazikika ndikuthandizira pazitsulo zokhala ndi tapered pamwamba ndi fungulo ndi hub, ndipo mphamvu yakunja ya axial imayendetsedwa ndi kunyamula kwa tapered roller. Kunyamula, mphamvu yamkati ya axial imatumizidwa ku chodzigudubuza chonyamulira cha mbali ina ya shaft kudzera pa slider.
Njira yothandizira theka-shaft yoyandama ndi yaying'ono komanso yopepuka, koma mphamvu ya theka-shaft imakhala yovuta, ndipo kusokoneza ndi kusonkhana kumakhala kovuta. Ngati ma axle shaft achotsedwa, galimotoyo sichitha kuthandizidwa pansi. Itha kugwiritsidwa ntchito pamagalimoto ang'onoang'ono ndi magalimoto opepuka okhala ndi magalimoto ang'onoang'ono, gudumu laling'ono m'mimba mwake ndi chitsulo cholumikizira kumbuyo, monga mndandanda wamba wa Wu ling ndi mndandanda wa Song hua jiang.
