ʻEnekini crankshaft flywheel hui pūʻulu
ʻO ka mua, crankshaft
ʻO Crankshaft kekahi o nā mea koʻikoʻi o ka mīkini, ʻo kāna hana ka pale ʻana i ke kaomi kinoea mai ka piston connecting rod group i ka torque o ka crankshaft a me ka puka waho, ʻo ia hoʻi, ua hoʻohana ʻia ka crankshaft e hoʻokele i ka mīkini valve mechanical. a me nā mea kōkua ʻē aʻe (e like me nā mea hoʻomohala, nā pā, nā ʻōpala wai, nā paila hoʻokele mana, nā mīkini pale kaulike, etc.)
Huila huila Crankshaft: 1- pulley; 2- huila kāʻei niho crankshaft manawa; 3- sprocket crankshaft; 4- Crankshaft; 5- crankshaft kumu nui (luna); 6- Huila lele; 7- mīkini hana hōʻailona ʻike wikiwiki; 8, 11- pahu pahu; 9- Crankshaft kumu nui (lalo); 10- Crankshaft poʻi halihali nui.
Ke hana nei ka crankshaft, pono ia e pale i nā hoʻololi manawa i ke kaomi kinoea, ka hoʻihoʻi ʻana i ka ikaika inertial a me ka ikaika centrifugal, a me kā lākou torque a me ka manawa kulou ma lalo o ka hana kiʻekiʻe, maʻalahi ke kulou a wili i ka deformation, no laila, pono ka ikaika o ka crankshaft. a me ka ʻoʻoleʻa, ke kūpaʻa maikaʻi a me ke kaulike maikaʻi. Hana ʻia ka crankshaft me ke kila kalapona maʻamau, a mālama ʻia ka ʻili o ka puke pai e ka quenching kiʻekiʻe a i ʻole nitriding. Hana ʻia ʻo Shanghai Santana engine crankshaft me ke kila kalapona kiʻekiʻe kiʻekiʻe. Hana ʻia nā ʻenekini Audi JW a me Yuchai YC6105QC me ke kumu kūʻai haʻahaʻa, ikaika kiʻekiʻe o ka hao ductile honua me ke kūpaʻa maikaʻi.
1. ʻO ke ʻano o ka crankshaft
ʻO ka crankshaft ka mea maʻamau i ka hopena mua, kahi ʻāʻī kumu nui, kahi crank, kahi counterweight, kahi puke pai hoʻohui a me kahi hope. Hoʻokumu ʻia ka crank me kahi puke pai lāʻau hoʻohui a me kāna mau puke pai hema a ʻākau. ʻO ka helu o ka crankshaft e pili ana i ka helu a me ka hoʻonohonoho ʻana o nā cylinders. ʻO ka crankshaft o kahi ʻenekini cylinder hoʻokahi wale nō ka crank; Ua like ka heluna o ka crankshaft o ka enekini laina me ka helu o na cylinders; Ua like ka heluna o na cranks ma ka crankshaft o ka enegini V me ka hapalua o ka helu o na cylinders. ʻO ke kumu mua o ka crankshaft ua hoʻolako ʻia me ka pulley, ka mīkini manawa, a me nā mea ʻē aʻe, i hoʻohana ʻia no ka hoʻokele ʻana i ka paila wai a me ka mīkini valve. Hoʻokomo ʻia ka ʻāʻī spindle o ka crankshaft i loko o ka noho lawe nui o ke kino cylinder a hoʻohana ʻia e kākoʻo i ka crankshaft. Hoʻohana ʻia ka puke pai lāʻau hoʻohui no ka hoʻokomo ʻana i ke koʻokoʻo hoʻohui, a hoʻopili ka crank i ka puke pai kumu kumu me ka puke pai lāʻau hoʻohui. I mea e kaulike ai i ka ikaika centrifugal i ka wā e huli ai ka crankshaft, ua hāʻawi ʻia kahi poloka kaulike ma ka crankshaft. Hāʻawi ʻia kahi flange hoʻohui ma ka hope o ka crankshaft e hoʻopili ai i ka lele lele i ka crankshaft e nā bolts. No ka lubricate i ka puke pai lāʻau hoʻohui, ua wili ʻia kahi ʻāpana lubricating mai ka puke pai kumu kumu a i ka puke pai lāʻau hoʻohui. He maʻalahi ka crankshaft integral i ka hoʻolālā, māmā i ke kaumaha a hilinaʻi i ka hana, a maʻamau e hoʻohana i nā bearings maʻamau, i hoʻohana nui ʻia i nā ʻenekini liʻiliʻi.
2. Layout loina o ka crank
ʻO ke ʻano o ka crankshaft a me ke kūlana pili o kēlā me kēia crank e hilinaʻi nui ʻia i ka helu o nā cylinders, ka hoʻonohonoho ʻana o nā cylinders a me ke ʻano hana o kēlā me kēia cylinder. I ka hoʻonohonoho ʻana i ke kaʻina hana ʻenekini, pono e hahai ʻia nā lula e like me ka hiki:
E hana i na cylinders o ka hana mau e like me ka mamao e hiki ai ke hoemi i ka ukana o ka halihali nui, a pale aku i ka puka ana o elua mau kiwikā pili e wehe ana i ka manawa like i ka wā o ka intake kaʻina hana, a me ka hanana o "air hopu" pili i ka inflation. ka pono o ka enekini.
(1) Pono e like ka huina hana o kēlā me kēia cylinder i mea e maʻalahi ai ka hana ʻana o ka ʻenekini. I loko o ka crankshaft Angle kahi e hoʻopau ai ka ʻenekini i kahi pōʻai hana, pono e hana kēlā me kēia cylinder i hoʻokahi manawa. No ka enegini eha-hu'i me ka helu pahu i, o ka huina hana he 720°/i. ʻO ia hoʻi, i kēlā me kēia 720°/i o ka crankshaft e loaʻa i ka cylinder no ka hana e hōʻoia i ka holo pono o ka ʻenekini.
(2) Inā he ʻenekini V-type, pono e hoʻololi nā kolamu hema a me ka ʻākau o nā cylinders.
3. ʻO ka hoʻonohonoho ʻana o ka ʻenekini multi-cylinder maʻamau a me ke kauoha hana
ʻO ka hoʻonohonoho ʻana o ka crankshaft a me ka crank o ka mīkini ʻehā-stroke in-line. ʻO ka huina hana Angle o ka ʻenekini ʻehā pahu ʻehā i loko o ka laina he 720 ° / 4 = 180 °, ua hoʻonohonoho ʻia nā crank ʻehā ma ka mokulele hoʻokahi, a ʻo ke kaʻina hana o ka mīkini (a i ʻole ke kaʻina ignition) he 1-3- 4-2 a i ʻole 1-2-4-3. ʻO ka mea hoʻohana maʻamau i hoʻohana ʻia he ʻaoʻao hoʻokahi semi-circular thrust pad me ka anti-friction metal layer, crankshaft main bearing with flanging and round thrust thrust pad he ʻekolu ʻano. ʻO ka pahu pahu he ʻāpana kila semi-ring me ka ʻaoʻao anti-friction alloy ma waho, i hoʻokomo ʻia i loko o ke awāwa o ke kino a i ʻole ka uhi uhi nui. I mea e pale aku ai i ka hoʻololi ʻana o ka pahu pahu, ua hoʻopaʻa ʻia ka puʻupuʻu i loko o ke awāwa. Hoʻohana kekahi mau pads pad i 4 ʻāpana e hana i ʻelua mau palena pōʻai maikaʻi, a hoʻohana kekahi i 2 mau ʻāpana. ʻO ka ʻaoʻao me ka metala anti-friction e kū pono i ka crankshaft.
Ua kūpaʻa ʻo Zhuo Meng Shanghai Auto Co., Ltd. e kūʻai aku i nā ʻāpana kaʻa MG&MAUXS e hoʻokipa ʻia e kūʻai.
