Likarolo tsa sehlopha sa crankshaft flywheel enjene
Ntlha ea pele, ke crankshaft
Crankshaft ke e 'ngoe ea likarolo tsa bohlokoa ka ho fetisisa tsa enjene, mosebetsi oa eona ke ho mamella khatello ea khase e tsoang sehlopheng se kopanyang piston ho torque ea crankshaft le tlhahiso ea kantle, ho feta moo, crankshaft e boetse e sebelisoa ho khanna mochini oa valve oa enjene. le lisebelisoa tse ling tse thusang (tse kang lijenereithara, li-fan, lipompo tsa metsi, lipompo tse tsamaisang motlakase, mochine oa ho leka-lekana, joalo-joalo)
Sehlopha se fofang sa Crankshaft: 1- pulley; 2- lebili la lebanta la leino la crankshaft nako; 3- crankshaft sprocket; 4- Crankshaft; 5- crankshaft main bearing (top); 6- Flywheel; 7- Jenereithara ea pontšo ea lebelo; 8, 11- letlapa le phunyeletsang; 9- crankshaft main bearing (ka tlase); 10- Sekoaelo se seholo sa Crankshaft.
Ha crankshaft e sebetsa, e tlameha ho mamella liphetoho tsa nako le nako khatellong ea khase, ho khutlisa matla a inertial le matla a centrifugal, hammoho le torque ea bona le motsotso oa ho khumama tlas'a ts'ebetso e phahameng haholo, e bonolo ho kobeha le ho sotha deformation, ka hona, crankshaft e lokela ho ba le matla a lekaneng. le ho satalla, ho hanyetsa ho apara hantle le ho leka-lekanya hantle. Crankshaft hangata e entsoe ka tšepe e mahareng ea carbon alloy, 'me bokaholimo ba koranta bo alafshoa ke ho tima kapa ho tima nitriding hangata. Crankshaft ea enjene ea Shanghai Santana e entsoe ka tšepe ea boleng bo holimo ea carbon steel. Lienjineri tsa Audi JW le Yuchai YC6105QC li entsoe ka tšepe e theko e tlase, e matla e sa tloaelehang ea lefatše e nang le khanyetso e ntle ea ho apara.
1. Sebopeho sa crankshaft
Crankshaft ka kakaretso e entsoe ka ntlha e ka pele, molala o ka sehloohong oa shaft, crank, counterweight, koranta ea rod e kopanyang le karolo e ka morao. Crank e entsoe ka koranta ea rod e hokahanyang le likoranta tsa eona tsa mantlha le letšehali le ka ho le letona. Palo ea crank ea crankshaft e itšetlehile ka palo le tlhophiso ea li-cylinders. Crankshaft ea enjene ea cylinder e le 'ngoe e na le crank e le' ngoe feela; Palo ea crankshaft ea enjene ea in-line e lekana le palo ea li-cylinders; Palo ea li-crank ka har'a crankshaft ea V enjene e lekana le halofo ea palo ea lisilindara. Mokotla o ka pele oa crankshaft o na le pulley, lisebelisoa tsa nako, joalo-joalo, tse sebelisetsoang ho khanna pompo ea metsi le mochine oa valve. Molala oa spindle oa crankshaft o kentsoe setulong se seholo sa 'mele oa cylinder' me o sebelisetsoa ho tšehetsa crankshaft. Koranta ea rod e kopanyang e sebelisoa ho kenya molamu o kopanyang, 'me crank e kopanya koranta e kholo ea shaft le koranta ea rod e kopanyang. E le ho leka-lekanya matla a centrifugal ha crankshaft e potoloha, ho fanoa ka "balance block" holim'a crankshaft. Ho fanoe ka flange e hokelang pheletsong e ka morao ea crankshaft ho hokahanya flywheel le crankshaft ka liboutu. Ho tlotsa jenale ea lithupa tse hokelang, ho chekoa phaseje ea ho tlotsa ho tloha ho jenale ea mantlha ea shaft ho ea ho jenale ea lithupa tse hokelang. The integral crankshaft e bonolo ka sebopeho, e bobebe ka boima ba 'mele ebile e ka tšeptjoa ts'ebetsong,' me ka kakaretso e nka li-bearings tse hlakileng, tse sebelisoang haholo lienjineng tse mahareng le tse nyane.
2. Layout molao-motheo oa crank
Sebopeho sa crankshaft le boemo bo lekanyelitsoeng ba crank ka 'ngoe haholo-holo li itšetlehile ka palo ea li-cylinders, tokisetso ea li-cylinders le mokhoa oa ho sebetsa oa silinda e 'ngoe le e' ngoe. Ha u hlophisa tatellano ea mosebetsi oa enjene, melao e latelang e lokela ho lateloa ka hohle kamoo ho ka khonehang:
Etsa hore li-cylinders tse peli tsa mosebetsi o tsoelang pele li arohane ka hohle kamoo ho ka khonehang ho fokotsa mojaro oa thepa e kholo, 'me u qobe ho hlaha ha li-valve tse peli tse amanang le ho bula ka nako e le' ngoe nakong ea ts'ebetso ea ho noa, 'me ketsahalo ea "moea grab" e ama theko ea lichelete. katleho ea enjene.
(1) Nako ea ho sebetsa Angle ea silindara e 'ngoe le e' ngoe e lokela ho lekana ho thusa ho sebetsa hantle ha enjene. Ka har'a Angle ea crankshaft moo enjene e qetang potoloho ea ho sebetsa, silindara ka 'ngoe e lokela ho sebetsa hang. Bakeng sa enjene ea li-stroke tse 'nè e nang le nomoro ea cylinder i, nako ea mosebetsi Angle ke 720 °/i. Ke hore, 720 °/i e 'ngoe le e 'ngoe ea crankshaft e lokela ho ba le cylinder bakeng sa mosebetsi ho netefatsa hore enjene e tsamaea hantle.
(2) Haeba e le enjene ea mofuta oa V, litšiea tse ka letsohong le letšehali le tse ka ho le letona li lokela ho fapanyetsana mosebetsi.
3. Tloaelo e tloaelehileng ea enjene ea li-cylinder tse ngata le taolo ea ho sebetsa
Tlhophiso ea crankshaft le crank ea enjene e nang le methapo e mene. Nako ea ho sebetsa Angle ea in-line-cylinder four-stroke enjene ke 720°/4=180°, crank e mene e hlophisitsoe ka sefofane se le seng, le tatellano ea enjene ea ho sebetsa (kapa tatellano ea ho hotetsa) ke 1-3- 4-2 kapa 1-2-4-3. Sesebediswa se sebediswang hangata se na le lehlakore le le leng la semi-circle thrust pad e nang le anti-friction layer, crankshaft main bearing with flanging le round thrust ring e na le mefuta e meraro. The thrust pad ke semi-ring steel sheet e nang le anti-friction alloy layer ka ntle, e kentsoeng ka har'a groove ea 'mele kapa sekoaelo se ka sehloohong. E le ho thibela ho potoloha ha "thrust pad", "thrust pad" e na le leqhubu le khomaretsoeng ka har'a groove. Li-thrust pads tse ling li sebelisa likotoana tse 4 ho theha meeli e 'meli e chitja, 'me tse ling li sebelisa likotoana tse 2 tsa meeli. Lehlakore le nang le tšepe ea anti-friction le lokela ho shebana le crankshaft.
