ʻO nā ʻāpana shaft kekahi o nā ʻāpana maʻamau i ʻike pinepine ʻia i nā mīkini.Hoʻohana nui ʻia e kākoʻo i ka hoʻoili ʻana

Nā ʻāpana, hoʻouna i ka torque a me ka ukana amo.ʻO nā ʻāpana shaft nā ʻāpana ʻoi aku ka lōʻihi ma mua o ke anawaena, a ʻo ka mea maʻamau i haku ʻia me ka ʻili cylindrical o waho, ka ʻili conical, ka lua i loko a me ke kaula o ka concentric shaft a me ka ʻili hope e pili ana.E like me nā ʻano hana like ʻole, hiki ke hoʻokaʻawale ʻia nā ʻāpana shaft i nā shaft optical, stepped shafts, hollow shafts a me crankshafts.

ʻO nā kumu me ka lākiō lōʻihi a me ka anawaena o ka liʻiliʻi ma lalo o 5, ua kapa ʻia ʻo nā kumu pōkole, a ʻo nā mea i ʻoi aku ka nui ma mua o 20, ua kapa ʻia nā kumu slender.ʻO ka hapa nui o nā pahu ma waena o nā mea ʻelua.

Kākoʻo ʻia ke kumu lāʻau e kahi bearing, a ʻo ka ʻāpana kumu i hoʻohālikelike ʻia me ka bearing i kapa ʻia ʻo ka puke pai.ʻO nā puke pai axle ka hōʻailona hui o nā shafts.ʻO ko lākou pololei a me ka maikaʻi o ka ʻili ke koi ʻia e kiʻekiʻe.Hoʻonohonoho ʻia kā lākou koi ʻenehana e like me nā hana nui a me nā kūlana hana o ka shaft, maʻamau nā mea aʻe:

(1) Ka pololei o ke ana.I mea e hoʻoholo ai i ke kūlana o ka lāʻau, pono maʻamau ka puke pai ʻana i ka pololei kiʻekiʻe (IT5 ~ IT7).ʻO ka maʻamau, haʻahaʻa haʻahaʻa ka nui o ka pololei o ka puke pai no ka hui ʻana i nā ʻāpana hoʻouna (IT6～IT9).

(2) Geometric shape accuracy ʻO ka pololei o ke ʻano geometric o nā ʻāpana kumu e pili ana i ka poepoe, cylindricity, etc. o ka puke pai, cone waho, Morse taper hole, etc. ʻO ka mea maʻamau, pono e kaupalena ʻia ke ahonui i loko o ka pae hoʻomanawanui.No nā ʻili o loko a me waho me nā koi ʻoi aku ka pololei, pono ke kaha ʻia ka ʻae ʻia ʻana ma ke kaha kiʻi.

(3) Kūlana Kūlike Kūlike ʻO nā koi kūpono o ke kūlana o nā ʻāpana shaft e hoʻoholo nui ʻia e ke kūlana a me ka hana o ka lāʻau i ka mīkini.ʻO ka mea maʻamau, pono ia e hōʻoia i nā koi coaxiality o ka puke pai o nā ʻāpana hoʻouna i hui ʻia i ka puke pai kumu kākoʻo, inā ʻaʻole ia e hoʻopilikia i ka pololei o ka lawe ʻana o nā ʻāpana hoʻouna (gears, etc.) a hoʻopuka i ka walaʻau.No nā lāʻau pololei maʻamau, ʻo ka holo ʻana o ka radial o ka ʻāpana kumu kūpono i ka puke pai kākoʻo ma ke ʻano he 0.01～0.03mm, a ʻo nā kumu kikoʻī kiʻekiʻe (e like me nā kumu nui) he 0.001～0.005mm.

(4) ʻO ka ʻili o ka ʻili ma ke ʻano maʻamau, ʻo ka ʻili o ke anawaena o ka lāʻau i hoʻohālikelike ʻia me ka ʻāpana hoʻouna ʻo Ra2.5～0.63μm, a ʻo ka ʻili o ke anawaena o ke kumu kākoʻo i hoʻohālikelike ʻia me ka bearing ʻo Ra0.63～0.16μm.

Nā hakahaka a me nā mea o nā ʻāpana lāʻau i pelu ʻia
(1) Nā ʻāpana shaft hiki ke koho ʻia nā ʻāpana shaft e like me nā blanks, forgings a me nā ʻano blank ʻē aʻe e like me nā koi hoʻohana, nā ʻano hana, nā kūlana lako a me ke ʻano.No nā lāʻau me ka liʻiliʻi o ke anawaena o waho, hoʻohana mau ʻia nā mea pā;no nā kuʻekuʻe wāwae a i ʻole nā ​​kumu koʻikoʻi me nā anawaena nui o waho, hoʻohana pinepine ʻia nā forgings, e mālama ai i nā mea a hoʻemi i ka hana o ka mīkini.E hoʻomaikaʻi i nā waiwai mechanical.

Wahi a nā unahi hana like ʻole, ʻelua ʻano o nā ʻano hana forging blank: free forging a make forging.Hoʻohana nui ʻia ka forging manuahi no ka hana liʻiliʻi a me ka liʻiliʻi, a hoʻohana ʻia ka die forging no ka hana nui.

(2) Pono nā ʻāpana shaft e koho i nā mea like ʻole a hoʻohana i nā kikoʻī lapaʻau wela like ʻole (e like me ka quenching and tempering, normalizing, quenching, etc.) e like me nā kūlana hana like ʻole a me nā koi hoʻohana e loaʻa ai kekahi ikaika, paʻakikī a me ke kūpaʻa Abrasion. .

ʻO ke kila 45 kahi mea maʻamau no nā ʻāpana kumu.He mea liʻiliʻi a ma hope o ke kinai ʻana a me ka hoʻomaʻamaʻa ʻana (a i ʻole normalizing), hiki ke loaʻa ka hana ʻokiʻoki maikaʻi, a hiki ke loaʻa iā ia nā waiwai mechanical piha e like me ka ikaika kiʻekiʻe a me ka paʻakikī.Ma hope o ke kinai ʻana, hiki i ka paʻakikī o ka ʻili ke piʻi i ka 45 ~ 52HRC.

Ua kūpono ke kila kila Alloy e like me 40Cr no nā ʻāpana shaft me ka pololei kūpono a me ka wikiwiki kiʻekiʻe.Ma hope o ka hoʻopiʻi ʻana a me ka hoʻoulu ʻana a me ka hoʻopau ʻana, ʻoi aku ka maikaʻi o kēia ʻano kila.

Ke lawe nei i ke kila GCr15 a me ke kila puna 65Mn, ma hope o ka hoʻopiʻi ʻana a me ka hoʻoheheʻe ʻana a me ka hoʻopau ʻana i ka ʻili kiʻekiʻe, hiki i ka paʻakikī o ka ʻili ke piʻi i 50-58HRC, a loaʻa ke kūpaʻa luhi kiʻekiʻe a me ke kūpaʻa maikaʻi ʻana, hiki ke hoʻohana ʻia e hana i nā kumu kiʻekiʻe.

Hiki ke koho i ka 38CrMoAIA nitride kila ke kumu nui o ka mīkini paʻahana (e like me ka huila wili o ka mea wili, ka spindle o ka mīkini hoʻoheheʻe jig).Ma hope o ka hoʻopau ʻana a me ka hoʻoulu ʻana a me ka nitriding surface, ʻaʻole hiki i kēia kila ke loaʻa ka paʻakikī o ka ʻili kiʻekiʻe, akā mālama pū nō hoʻi i kahi kumu palupalu, no laila he hopena maikaʻi a me ka paʻakikī.Hoʻohālikelike ʻia me ke kila carburized a paʻakikī, loaʻa iā ia nā hiʻohiʻona o ka deformation mālama wela liʻiliʻi a ʻoi aku ka paʻakikī.

Hoʻohana nui ʻia ke kila 45 No.Akā, he kila kalapona waena kēia, a ʻaʻole maikaʻi kāna hana kinai ʻana.No. 45 kila hiki ke kinai i HRC42 ~ 46.No laila, inā makemake ʻia ka paʻakikī o ka ʻili a makemake ʻia ka ʻoihana ʻoi aku ka maikaʻi o ke kila 45 #, e hoʻopau pinepine ʻia ka ʻili o 45 # kila (kiʻekiʻe-frequency quenching a pololei quenching), i hiki ke loaʻa ka paʻakikī o ka ʻili.

'Ōlelo Aʻo: No. 45 kila me ke anawaena o 8-12mm hiki i nā māwae i ka wā quenching, he pilikia paʻakikī.ʻO nā ʻano hana i kēia manawa ʻo ka hoʻoulu ʻana o ka hāpana i ka wai i ka wā e hoʻopio ai, a i ʻole ka hoʻoluʻu ʻaila e pale aku i nā māwae.
