Kuphatikiza pazigawo zomwe zakhazikitsidwa kale, Timken wapanga njira zisanu zomwe zimagwiritsidwa ntchito nthawi zambiri zodzipangira zokha chilolezo (mwachitsanzo, SET-RIGHT, ACRO-SET, PROJECTA-SET, TORQUE-SET ndi CLAMP-SET) monga njira zosinthira pamanja.Onani Table 1-"Kufanizira njira zololeza zodzigudubuza" kuti muwonetse mawonekedwe osiyanasiyana a njirazi patebulo.Mzere woyamba wa tebuloli umafanizira kuthekera kwa njira iliyonse kuwongolera moyenera "mndandanda" wa chilolezo chokhazikitsa.Izi zimangogwiritsidwa ntchito kuwonetsa mawonekedwe onse a njira iliyonse pakukhazikitsa chilolezo, mosasamala kanthu kuti chilolezocho chimayikidwa "preload" kapena "axial clearance".Mwachitsanzo, pansi pa gawo la SET-RIGHT, kuyembekezera (nthawi yayitali kwambiri kapena 6σ) kusintha kwa chilolezo, chifukwa cha kulekerera kwapadera ndi kulamulira kwanyumba / shaft, kungakhale kosiyana ndi 0.008 mainchesi mpaka 0.014 mainchesi.Chilolezo chololeza chikhoza kugawidwa pakati pa chilolezo cha axial ndi preload kuti apititse patsogolo ntchito ya kubereka / kugwiritsa ntchito.Onani Chithunzi 5-"Kugwiritsa Ntchito Njira Yodziwikiratu Kuti Mukhazikitse Chilolezo".Chiwerengerochi chimagwiritsa ntchito kapangidwe ka thirakitala yaulimi ya mawilo anayi monga chitsanzo kusonyeza kagwiritsidwe ntchito ka njira yololeza kuloleza kuloleza zodzigudukira.
Tikambirana mwatsatanetsatane matanthauzo, malingaliro ndi njira zokhazikika za kagwiritsidwe ntchito ka njira iliyonse m'mitu yotsatirayi ya gawoli.Njira ya SET-RIGHT imapeza chilolezo chofunikira powongolera kulolerana kwa kunyamula ndi kukhazikitsa, popanda kufunikira kosintha pamanja TIMKEN tapered roller bear.Timagwiritsa ntchito malamulo a kuthekera ndi ziwerengero kulosera zotsatira za kulolerana kumeneku pakupereka chilolezo.Kawirikawiri, njira ya SET-RIGHT imafuna kulamulira kolimba kwa kulekerera kwa machining a shaft / nyumba yonyamula katundu, ndikuwongolera mosamalitsa (mothandizidwa ndi magiredi olondola ndi ma code) kulolerana kofunikira kwa mayendedwe.Njirayi imakhulupirira kuti chigawo chilichonse mumsonkhanowu chimakhala ndi zololera zovuta ndipo ziyenera kuyendetsedwa mkati mwazosiyana.Lamulo la kuthekera likuwonetsa kuti kuthekera kwa gawo lililonse mumsonkhano kukhala kulolerana kwapang'ono kapena kuphatikiza kulekerera kwakukulu ndi kochepa kwambiri.Ndipo kutsatira "yachibadwa kugawa kulolerana" (Chithunzi 6), malinga ndi malamulo ziwerengero, ndi superposition zigawo zikuluzikulu zonse amakonda kugwa pakati zotheka osiyanasiyana kulolerana.Cholinga cha SET-RIGHT njira ndikuwongolera kulolerana kofunikira kwambiri komwe kumakhudza kubereka chilolezo.Kulekerera uku kumatha kukhala mkati mwazonyamula, kapena kungaphatikizepo zida zina zomangirira (ie, m'lifupi A ndi B mu Chithunzi 1 kapena Chithunzi 7, komanso shaft yakunja ndi m'mimba mwake yamkati).Chotsatira chake ndi chakuti, ndi mwayi waukulu, chilolezo choyikapo chonyamula chidzagwera mu njira yovomerezeka ya SET-RIGHT.Chithunzi 6.
