Dayamita ya chozungulira cha treadmill: Chizindikiro chocheperako cha kulimba
M'makalabu akuluakulu olimbitsa thupi, ma roller a ma treadmill amalonda omwe akhala akugwira ntchito kwa zaka zoposa khumi nthawi zambiri amakhala okhuthala ndi 30% kapena kuposerapo kuposa a ma modelo apakhomo. Izi sizongochitika mwangozi koma chisankho chaukadaulo chomwe chimasankha nthawi yogwiritsira ntchito zidazo.
Anthu ogula malo olimbitsa thupi komanso mahotela akamayesa kufunika kwa makina ochitira masewera olimbitsa thupi kwa nthawi yayitali, nthawi zambiri amafufuza mosamala mphamvu ya injini ndi makulidwe a lamba wothamanga, koma nthawi zambiri amanyalanyaza chinthu chofunikira chonyamula katundu chomwe chimabisika mkati mwake - kukula kwa ma roller.
Chozungulira, monga maziko a makina opatsira magiya a treadmill, chimatsimikizira mwachindunji momwe magetsi amagwirira ntchito, kuchuluka kwa phokoso, komanso chofunika kwambiri, katundu pa mabearing ndi mota.
01 Mfundo Zauinjiniya Zonyalanyazidwa
Anthu ambiri akamaganizira kwambiri za ma treadmill, chinthu choyamba chomwe amawona ndi digito panel, m'lifupi mwa lamba wothamanga kapena mphamvu yamphamvu ya akavalo. Komabe, pansi pa ntchito yamphamvu kwambiri kwa maola angapo tsiku lililonse, ndi ma roller awiri achitsulo obisika pansi pa lamba wothamanga omwe amanyamuladi mphamvu yamakina yosalekeza.
M'mimba mwake mwa chozunguliracho kwenikweni ndi kugwiritsa ntchito kwenikweni kwa mfundo ya lever. M'mimba mwake waukulu umatanthauza kuti Ngodya yomwe lamba limapindika ndi yosalala, zomwe zimachepetsa mwachindunji kutentha kwamkati ndi kutayika kwa kukangana komwe kumachitika pamene lamba wothamanga akupindika. Mutha kuganiza kuti pamene chitoliro chamadzi chokhuthala ndi chitoliro chopyapyala chamadzi zimadutsa mumadzi ofanana, kukana kwa madzi mkati mwa chitoliro choyamba kumakhala kochepa kwambiri.
Mukagwiritsa ntchito mosalekeza, kukula kochepa kwa chozungulira kudzakakamiza lamba wothamanga kuti apinde ndi kukulunga pa ngodya yakuthwa. Izi sizimangowonjezera kutopa kwa lamba wothamanga, kufupikitsa nthawi yake yosinthira, komanso zimatumiza mphamvu yayikulu ya radial ku dongosolo lonyamula katundu kumapeto onse a chozungulira, zomwe zimapangitsa kuti chiwonongeke mwachangu.
02 Malingaliro a makina a mphamvu yonyamula katundu
Mphamvu yonyamula katundu ya chozungulira siimangogwirizana ndi kukula kwake kokha. Malinga ndi mfundo za kachitidwe ka zinthu, kukana kupindika kwa axis kumagwirizana mwachindunji ndi kyubiki ya kukula kwake. Izi zikutanthauza kuti kuwonjezera kukula kwa chozungulira kuchoka pa mamilimita 50 kufika pa mamilimita 55 (kuwonjezeka kwa 10%) kokha kungawonjezere mphamvu yake yopindika ndi pafupifupi 33%.
Kuwonjezeka kwa mphamvu kumeneku n'kofunika kwambiri kwazochitika zamalonda kapena zitsanzo zapakhomo zopangidwa kwa ogwiritsa ntchito olemera kwambiri.Pa nthawi yoyendetsa, mphamvu yogunda ya sitepe iliyonse yomwe wogwiritsa ntchito amafika imaposa kulemera kwake kosasinthasintha. Katundu wogundayu pamapeto pake amasamutsidwira ku ma roller akutsogolo ndi akumbuyo kudzera mu lamba wothamanga. Dayamita yokwanira imatha kufalitsa mphamvu zogundazi ndikuletsa ma roller kuti asawonongeke ndi microscopic.
Ngakhale kuti kusinthaku sikuoneka ndi maso, ndi chimodzi mwa zifukwa zazikulu zomwe zimapangitsa kuti bearing iyambe kulephera komanso phokoso losazolowereka la treadmill. Kupanikizika kosalekeza kungayambitse kuwonongeka kwa mabearing raceways, kusokoneza mafuta, ndipo pamapeto pake kumabweretsa phokoso komanso kumafuna kukonza kokwera mtengo.
03 Mulingo wa nthawi yolimba
Kulimba si mkhalidwe koma njira yomwe imawonongeka pakapita nthawi. Kukula kwa chozungulira kumakhudza mwachindunji kutsetsereka kwa curve iyi yochepetsera.
Ma roller okhala ndi mainchesi akuluakulu amakhala ndi mphamvu zochepa zonyamula katundu pa ma bearing awo. Pogwiritsa ntchito mphamvu yomweyo, nthawi yogwira ntchito yodalirika ya bearing mkati mwa moyo wake wovomerezeka ndi yayitali. Izi zikutanthauza kuti nthawi yosamalira zinthu nthawi yayitali imakhala yochepa komanso ndalama zosinthira ziwalo, zomwe ndi gawo lofunika kwambiri pakuwerengera ndalama zonse za umwini pakugula B2B.
Kuchuluka kwa mainchesi kumatanthauzanso malo akuluakulu otenthetsera kutentha. Pakagwira ntchito mwachangu kwambiri, kukangana pakati pa ma rollers ndi lamba wothamanga kumabweretsa kutentha. Kutentha kwambiri kumatha kuwononga chophimba chakumbuyo kwa lamba wothamanga ndikukhudza magwiridwe antchito a mafuta opaka. Ma rollers okhuthala amatha kuyeretsa kutentha kumeneku bwino, zomwe zimapangitsa kuti makina onse otumizira magetsi azigwira ntchito kutentha koyenera.
Kutengera ndi zomwe zachitika, makina ambiri opumira omwe nthawi zambiri sagwira ntchito bwino nthawi zambiri amapeza kuti kukula kwa makina awo akutsogolo (ma drive rollers) sikukwanira atachotsedwa. Izi zimapangitsa kuti injini ifunike kutulutsa mphamvu zambiri kuti igonjetse kukana kowonjezereka, kukhalabe mu mkhalidwe wolemera kwa nthawi yayitali ndikufupikitsa moyo wonse wa makinawo.
04 Kugwirizana kosaoneka pakati pa Diameter ndi nthawi ya moyo wa malamba othamanga
Lamba wothamanga ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito pa treadmill. Mtengo wake wosinthira komanso nthawi yomwe sagwira ntchito zimakhudza mwachindunji zomwe ogwiritsa ntchito amakumana nazo komanso momwe amagwirira ntchito. Pali kulumikizana mwachindunji pakati pa kukula kwa chozungulira ndi nthawi yomwe lamba wothamanga amagwirira ntchito.
Lamba wothamanga akamazungulira chozungulira chaching'ono, kutopa kwake kopindika kumawonjezeka kwambiri. Nsalu ya ulusi ndi chophimba pamwamba pa lamba wothamanga zimakhala ndi ming'alu yaying'ono komanso kugawanika mwachangu mukapindika mobwerezabwereza. Izi zili ngati kupinda waya wachitsulo mobwerezabwereza. Ngodya ikakuthwa, imasweka mwachangu.
Mosiyana ndi zimenezi, ma rollers akuluakulu amapereka njira yosinthira yofewa ya lamba wothamanga, zomwe zimachepetsa kwambiri kupsinjika kumeneku. Izi sizimangowonjezera nthawi yogwira ntchito ya lamba mmodzi wothamanga, komanso zimaonetsetsa kuti imasunga kupsinjika kokhazikika komanso kugwira ntchito bwino nthawi yonse ya moyo wake.
05 Momwe Mungayesere ndi Kusankha
Kwa ogula akatswiri, ndikofunikira kumvetsetsa momwe angayesere kukula kwa ma roller. Izi sizikutanthauza kungoyang'ana nambala, koma kuiyika mkati mwa kapangidwe ka chinthu chonsecho.
Choyamba, chisamaliro chiyenera kuperekedwa ngati mainchesi a ma roller akutsogolo ndi akumbuyo ndi osiyana. Kawirikawiri, mainchesi a roller yakumbuyo (shaft yoyendetsedwa) ikhoza kukhala yaying'ono pang'ono, koma roller yakutsogolo (shaft yoyendetsa, yolumikiza mota) iyenera kuwonetsetsa kukula kokwanira chifukwa ndiyo gawo lalikulu lotumizira mphamvu ndi katundu.
Kachiwiri, ndikofunikira kuganizira kuchuluka kwa mphamvu zopitilira muyeso zamakina opondapo mapazi. Mphamvu yamphamvu ya akavalo iyenera kufananizidwa ndi kukula kwa roller diameter yayikulu kuti injiniyo ipereke mphamvu moyenera komanso bwino, m'malo mowononga mphamvu polimbana ndi kukana kosafunikira kwa makina.
Pomaliza, ganizirani mphamvu ya ogwiritsa ntchito omwe mukufuna kuwagwiritsa ntchito. Pa malo amalonda komwe kugwiritsidwa ntchito tsiku ndi tsiku kumapitirira maola 4, kapena pazitsanzo zapakhomo zomwe zimapangidwira ogwiritsa ntchito omwe ali ndi mphamvu zambiri, ndi bwino kuyika patsogolo kapangidwe ka roller yakutsogolo yokhala ndi mainchesi opitilira 55 kuti zitsimikizire kudalirika kwa nthawi yayitali.
Posankha, kukula kwa chozungulira sikuyenera kuwonedwa kokha, koma ngati chizindikiro cha ngati wopanga akufuna kuyika ndalama mu kapangidwe ka makina. Makampani omwe amasamala izi nthawi zambiri amagwiritsa ntchito miyezo yofanana ya uinjiniya m'zigawo zina zofunika monga ma mota ndi makina owongolera.
Pamene makampani opanga masewera olimbitsa thupi anasintha kuchoka pa kugulitsa zida kupita ku kupereka luso lolimba lokhazikika komanso lodalirika, kuyang'ana kwambiri pa kulimba kwa zida ndi ndalama zokonzera zida kunafika pamlingo wapamwamba kwambiri. Kukula kwa chozungulira, chomwe chimabisika pansi pa lamba wothamanga, ndiye maziko ofunikira kwambiri aukadaulo omwe amalumikiza chisankho choyamba chogula ndi kukhutira kwa nthawi yayitali pantchito.
Nthawi ina mukadzayesa makina opukutira matayala, mungafunsenso funso lina lokhudza kukula kwa ma roller. Yankho ili silimangowonetsa nthawi yomwe chipangizocho chidzakhalapo, komanso limasonyeza kumvetsetsa kwenikweni kwa wopanga za mtengo wa chinthucho kwa nthawi yayitali.
