① Xa indawo yokunyamezela idiamitha yangaphakathi kunye nendawo yokunyamezela ishaft yenza ilingane, ikhowudi yonyamezelo eyiyeyenguquko eyiyeyona ingena kwisiseko somngxuma jikelele iya kuba yinto yokuphumelela ngaphezulu, njenge k5, k6, m5, m6, n6 , njl., kodwa isixa-mali esiphumeleleyo asisikhulu; xa ukunyamezela kwe-diameter yangaphakathi yokuthwala ihambelana ne-h5, i-h6, i-g5, i-g6, njl., akusiyo imvume kodwa i-over-win fit.

②Ngenxa yokuba ixabiso lonyamezelo lokuthwala i-diameter yangaphandle lihlukile kwi-shaft yereferensi ngokubanzi, ikwayindawo ekhethekileyo yokunyamezela. Kwiimeko ezininzi, ikhonkco yangaphandle igxininiswe kumngxuma wezindlu, kwaye ezinye iinqununu zokuthwala kufuneka zilungelelaniswe ngokweemfuno zesakhiwo, kwaye ukulungelelaniswa kwazo akufanelekanga. Iqinile kakhulu, ihlala isebenzisana ne-H6, H7, J6, J7, Js6, Js7, njl.

I-Attachment: Phantsi kweemeko eziqhelekileyo, i-shaft iphawulwe ngokubanzi nge-0 ~+0.005. Ukuba ayisoloko ichithwa, ingu +0.005~+0.01 uphazamiseko olufanelekileyo. Ukuba ufuna ukuqhawula rhoqo, lutshintsho olufanelekileyo. Kwakhona kufuneka siqwalasele ukwanda kwe-thermal ye-shaft material ngokwayo ngexesha lokujikeleza, ngoko ke ubukhulu becala, ukulungelelaniswa kwe-clean-clean ngu-0.005 ~ 0, kwaye ubuninzi be-clean clearance akufanele budlule i-0.01. Enye enye kukuphazamiseka kwekhoyili ehambayo kunye nokucocwa kwendandatho emileyo.

Ukuthwala ukulingana ngokuqhelekileyo kukutshintsha kokufaneleka, kodwa ukungenelela kokuphazamiseka kuyakhethwa kwiimeko ezikhethekileyo, kodwa kunqabile. Ngenxa yokuba umdlalo phakathi kwe-bearing kunye ne-shaft ngumdlalo phakathi kwendandatho yangaphakathi yokuthwala kunye ne-shaft, inkqubo ye-hole yesiseko isetyenziswa. Ekuqaleni, ukuthwala kufuneka kube ngu-zero ngokupheleleyo. Xa ubuncinci bobungakanani bomda buhambelana, i-ring yangaphakathi iyaqengqeleka kwaye yonakalise umphezulu we-shaft, ngoko ke umsesane wethu wangaphakathi wokuthwala unonyamezelo olusezantsi lokutenxa kwe-0 ukuya kwi-μ ezininzi ukuqinisekisa ukuba iringi yangaphakathi ayijikelezi, ngoko ke ukuthwala kukhetha ngokubanzi. utshintsho olulungeleyo, nokuba nokuba ukutshintshwa kwenguqu kukhethiwe, ukuphazamiseka akufanele kudlule iingcingo ezi-3.

Inqanaba lokuchaneka lokuchaneka likhethwa ngokubanzi kwinqanaba 6. Ngamanye amaxesha kuxhomekeke kwizinto eziphathekayo kunye nokucubungula iteknoloji. Kwithiyori, inqanaba lesi-7 lincinci, kwaye ukuba lihambelana nenqanaba lesi-5, ukugaya kuyadingeka.
