Zvinoenderana nekutenderera kwemutoro unoshanda pabhero zvichienderana nering, kune marudzi matatu emitoro iyorolling bearring bears: mutoro wemunharaunda, cyclic load, uye swing load. Kazhinji, iyo cyclic mutoro (kutenderera mutoro) uye kutenderera mutoro unoshandisa kusimba kwakasimba; kunze kwezvinodikanwa zvakakosha zvemitoro yenzvimbo, kazhinji haina kukodzera kushandisa yakasimba. Kana rin'i inokunguruka ichiiswa pasi pemutoro une simba uye iine mutoro unorema, mhete dzemukati nedzekunze dzinofanira kutora kupindirana kwakakodzera, asi dzimwe nguva mhete yekunze inogona kuregedzeka zvishoma, uye inofanirwa kunge inokwanisa kufamba axially mune inotakura imba. imba gomba; apo Kana mhete yekutakura inoiswa pasi pemitoro inotenderera uye mutoro wacho wakareruka, zvishoma zvishoma zvakasununguka kupfuura zvakagadzikana zvinogona kushandiswa.

Saizi yemutoro

Kupindirana pakati pemhete yekutakura uye shaft kana gomba reimba kunoenderana nehukuru hwemutoro. Kana mutoro wacho uchirema, kupindira kukuru kunoshandiswa kunoshandiswa; kana mutoro wacho wakareruka, kupindira kuduku kunoshandiswa kunoshandiswa. Kazhinji, kana radial load P iri pasi pe 0.07C, iine mutoro wakareruka, apo P yakakura kudarika 0.07C uye yakaenzana kana pasi pe 0.15C, inowanzoitika, uye kana P yakakura kudarika 0.15C, iwo mutoro unorema (C ndiyo yakatemerwa dynamic load yekutakura).

Kushanda tembiricha

Kana kutakura kuri kushanda, kutonhora kwechigadziko kunowanzokwira kudarika kutonhora kwezvikamu zviri pedyo. Nokudaro, mhete yemukati yekutakura inogona kusununguka ne shaft nekuda kwekuwedzera kwekushisa, uye mhete yekunze inogona kukanganisa kufamba kweaxial yekutakura mugomba reimba nekuda kwekuwedzera kwekushisa. Paunosarudza iyo yakakodzera, mutsauko wekushisa uye kuwedzera uye kuputika kwechigadzirwa chekutakura kunofanira kuverengwa. Kana mutsauko wekushisa wakakura, kupindira kwakakodzera pakati pe shaft nemhete yemukati kunofanira kuva yakakura.

Kutenderera chaiko

Kana iyo kutakura iine yakakwirira kutenderera kwechokwadi zvinodiwa, kuitira kuti ubvise pesvedzero ye elastic deformation uye vibration, kushandiswa kwe clearance fit kunofanirwa kudziviswa.

Chimiro uye zvinhu zvekutakura imba yakabereka

Nokuda kwegomba reimba yepamutemo, hazvikurudzirwi kushandisa kupindirana kwakakodzera paunenge uchisangana nebhengi rekunze rinotakura, uye mhete yekunze haifaniri kutenderedzwa mugomba reimba. Pamabhengi akaiswa pamadziro akatetepa, simbi-yechiedza, kana maburi mashaft, akasimba anofanira kushandiswa pane madziro akakora, simbi, kana mashaft akasimba.

Kuisa nyore uye disassembly

Pamichina inorema, yakasununguka fit inofanirwa kushandiswa kune mabheya. Kana kusungirirwa kwakasimba kuchidikanwa, kutakura kwakaparadzaniswa, bheji rakaputika mukati memhete yemukati uye kutakura neadapter sleeve kana sleeve yekubvisa inogona kusarudzwa.

Axial kusimuka kwekubereka

Munguva yekukodzera, kana mhete yekutakura ichidikanwa kuti ikwanise kufamba axially panguva yekushanda, mhete yekunze yekutakura uye gomba reimba yekuberekaimba inofanira kutora yakasununguka fit.

Sarudzo yekukwana

Kufananidza pakati pekubereka uye shaft inotora base hole system, uye inofananidzwa neimba inotora base shaft system. Iko kukwana pakati pekubereka uye shaft kwakasiyana neiyo tolerance fit system inoshandiswa muindasitiri yekugadzira muchina. Iyo yekushivirira nzvimbo yemukati dhayamita yekubereka inonyanya pazasi shanduko. Nokudaro, pasi pemamiriro ehutano hwakafanana, chiyero chakakodzera chemukati wekubereka uye shaft inowanzova yakasimba. . Kunyangwe iyo nzvimbo yekushivirira yedhayamita yekunze yekutakura uye nzvimbo yekushivirira yeiyo base shaft system zvese zviri pazasi pemutsara zero, hunhu hwavo hauna kufanana neyakajairwa kushivirira system.
