ʻO ka Wind Turbine Main Shaft Bearing Housing kahi mea hoʻokumu kumu i nā turbines makani axis horizontal, kuleana no ke kākoʻo ʻana i ka shaft rotor a me ka lawe ʻana i nā ukana aerodynamic i ka nacelle frame. Ke hana nei ma lalo o ka hoʻouka ʻana i ka pōʻaiapuni, nā ʻano wela wela, a me 20+ mau makahiki e pono ai ke ola ola, koi kēia ʻāpana i ka ikaika luhi ʻokoʻa, ke kūpaʻa dimensional, a me ke kani metallurgical.
Hoʻokumu ʻo Ningbo Ruican i kēia hale ma o ka hoʻoheheʻe ʻana i ka waiwai o QT700-2 ductile iron, a ukali ʻia e 5-axis CNC machining o nā ʻāpana noho koʻikoʻi, nā kumu hole bolt, a me nā pilina pili. ʻO kā mākou hana i hoʻohui ʻia e hōʻoia i ka traceability piha mai ka mea maka a hiki i ka mea i hoʻopau ʻia.
