Ndinofanira Kusimbisa Bolt kana Nut muBolt-Nut Connection?

Mukubatanidza kune threaded, ndingasarudza sei pakati pekuomesa nati nekusimbisa bhaudhi?

Mukubatanidza ne threaded, mubvunzo wekuti kuomesa nati kana kuomesa bhaudhi haidi kutariswa kune riveted rivets, rivet nuts, welded welded nuts, welded bolts, etc. Uyezve, kana uchishandisa zvidzitiro, hapana chikonzero chekufunga nezvenyaya iyi, iyo nut chete inogona kusimbiswa.

Kunyangwe kuomesa bhaudhi kana kuti nati inowanzoonekwa mune bolt-nut yekubatanidza. Mumamiriro ezvinhu akawanda ekushanda, kana pasina zvakakosha zvinodiwa, nut inonyanya kusimbiswa kuti isimbise kubatana. Zvisinei, mumamiriro ezvinhu anokosha apo nzvimbo yekushanda inogumira uye chigadziro chekusimbisa chisingagoni kushandiswa, nati inotanga kusungirirwa, uye ipapo bhaudhi ichasimbiswa kuti iwane kubatana kwakasimbiswa.

Ndeupi musiyano uripo pakati pekuomesa nati nekusimbisa bhaudhi?

Musiyano mukuru pakati pekusimbisa bhaudhi nekusimbisa nati ndeyekuti friction coefficient yakasiyana, izvo zvinozotungamira kune mutsauko mu preload simba rebhoti pasi peiyo torque imwechete. Kana iyo preload simba ichida kunyatsodzorwa, pachave nemusiyano pakati pezviviri. Nekudaro, kana iyo friction coefficient uye dhayamita yerutsigiro yakafanana, iyo tensile stress uye torsional shear stress yekusimbisa bhaudhi nenati zvakafanana, uye zvakanaka kuomesa imwe neimwe. Kubva pamaonero echivanhu, vanhu vanokasira nzungu kakawanda.

Iko hakuna chiyero chakakodzera chinoti mabhaudhi kana nzungu dzinofanirwa kukwizwa. Panyaya yezvishandiso zvekushandisa zvekumanikidza, chipanera chipfupi chesoketi chinogona kushandiswa kukwenya mabhaudhi. Paunenge uchitsvaira nzungu, kureba kwakafumurwa kwemabhoti kunoda kutariswa. Iyo socket wrench inowanzo shandiswa yakareba, izvo zvinogona kuwedzera mamwe mari. Nekudaro, mune akawanda anti-kutenderera tooling madhizaini, marefu socket wrenches anoshandiswawo kusevha mabhaudhi, saka mune iyi nyaya, screwing bolts uye screwing nzungu hazvina kunyanya kusiyana.

Chikonzero nei vanhu vachiwanzo kukora nzungu ndechekuti kana mabhaudhi asina kurongeka, pachave nekukweshana pakati pesikurwa negomba rakagara rakagadzirwa, nekudaro vachiwedzera friction torque uye kuwedzera torque yekupinza, nepo screwing nuts haina dambudziko iri.

Muchidimbu, screwing bolts uye nzungu zvakafanana muzviitiko zvakawanda. Kubva pakuona kwekureruka, nzungu dzinonyanya kupetwa. Kunze kwekunge zvisingaite kupura nzungu pasi pemamiriro ekushanda akakosha, wobva wasarudza kukora mabhaudhi. Ehe, zvakanakisa kutsanangura kana uchigadzira kana kupura nzungu kana mabhaudhi kuitira kuti uzadzise dhizaini preload zvinodiwa.
