Nā ʻāpana Sintered no nā ʻāpana kaʻa

Nā ʻāpana i hoʻopaʻa ʻiaʻO nā huahana sintered i hana ʻia mai ka pauka a hoʻoikaika ʻia e ka sintering. Hōʻike pinepine ʻia nā ʻāpana Sintered e nā ʻae paʻa a me ka maʻalahi o ka hoʻokomo ʻana. Aia i loko o ka hui ʻana o ka pauda kahi lubricant e hōʻemi i ka friction i hana ʻia i ka wā kaomi. ʻO ka hui pauka ka mea mua i hoʻohana ʻia i ka hana ʻana i nā ʻāpana sintered. Hiki ke hao maʻemaʻe ka pauka kumu, ke kila kila haʻahaʻa, ke kila kila a i ʻole ke kila māmā. Hiki ke hoʻololi ʻia nā waiwai o ka ʻāpana hope e ka hoʻohana ʻana i nā mea hoʻohui e like me carbon, alloying elements a me nā mea hoʻonui machinability. Loaʻa i nā huila pauda nā lubricants e hōʻemi i ka friction i hana ʻia i ke kaomi ʻana. ʻO ke ala maʻamau o ka paʻi ʻana ʻo ia ke kaomi axial i ke kila a i ʻole carbide make. Hiki i nā mīkini mīkini a i ʻole nā ​​kaomi hydraulic ke hana i nā koi koi o 400-800 MPa. Hiki ke paʻi ʻia nā ʻāpana ʻano paʻakikī i kahi kaʻina hana hoʻokahi a me ka huahana kiʻekiʻe a hiki i 25 mau ʻāpana i kēlā me kēia minuke. Ma hope o ke kaomi ʻana, paʻi ʻia nā ʻāpana i kahi ʻano i ʻike mua ʻia a me ka nui. Akā naʻe, ʻaʻole kēia ka nui a i ʻole ka ikaika.

Ka Pono oKaʻina Hana Metala Paʻa

1. Pono ke kumu kūʻai
Hiki ke hoʻopaʻa ʻia nā huahana hope me ke ʻano metallurgy pauka, ʻaʻole pono a hoʻopōkole paha i ka hana ʻana o ka mīkini.

2. Nā ʻano paʻakikī
Hiki i ka Powder mtallurgy ke loaʻa i nā ʻano paʻakikī mai ka mea hana paʻa, me ka ʻole o ka hana machining, nā niho, nā splines, nā profiles, nā geometries frontal etc.

3. Kiekie pololei
Hiki ke hoʻomanawanui ʻia i ka ʻaoʻao perpendicular o ka hoʻopaʻa ʻana ma ke ʻano he π 8-9 e like me ka sintered, hiki ke hoʻonui ʻia a hiki i T 5-7 ma hope o ka nui ʻana. Hiki i nā hana machining hou ke hoʻomaikaʻi i ka pololei

4. Lubrication pono'ī
Hiki ke hoʻopiha ʻia ka porosity pili o ka mea me nā aila, a laila e loaʻa iā ia kahi lubricating bearing: hāʻawi mau ka ʻaila. lubrication ma waena o ka bearing a me ka shaft, a ʻaʻole pono ka ʻōnaehana i kahi lubricant waho.

5. ʻenehana ʻōmaʻomaʻo
ʻO ke kaʻina hana o nā ʻāpana sintered i hōʻoia ʻia e like me ka ecological, no ka mea he haʻahaʻa loa ka ʻōpala, hiki ke hana hou ʻia ka huahana, a maikaʻi ka ikehu no ka mea ʻaʻole i hoʻoheheʻe ʻia ka mea.
