Moteri crankshaft flywheel yibigize itsinda
Ubwa mbere
Crankshaft ni kimwe mu bice byingenzi bya moteri, imikorere yacyo ni ukurwanya umuvuduko wa gaze uva muri piston ihuza itsinda ryinkoni mu muriro wa crankshaft n’ibisohoka hanze, byongeye kandi, igikonjo nacyo gikoreshwa mu gutwara moteri ya valve ya moteri nibindi bikoresho bifasha (nka generator, abafana, pompe zamazi, pompe ziyobora ingufu, uburyo bwo kuringaniza shaft, nibindi)
Itsinda rya flake ya Crankshaft: 1- pulley; 2- crankshaft igihe cyumukandara wumukandara; 3- igikonoshwa; 4- Crankshaft; 5- crankshaft nyamukuru ifite (hejuru); 6- Flywheel; 7- Umuvuduko wibyuma byerekana ibimenyetso; 8, 11- gusunika padi; 9- crankshaft nyamukuru ifite (hepfo); 10- Crankshaft nyamukuru itwikiriye.
Iyo crankshaft ikora, igomba guhangana nimpinduka zigihe cyumuvuduko wa gaze, igasubirana imbaraga zidafite ingufu nimbaraga za centrifugal, hamwe nigihe cyumuriro nigihe cyo kugunama mugihe cyihuta cyihuse, byoroshye kugoreka no guhindagurika, kubwibyo, igikonjo kigomba kugira imbaraga zihagije no gukomera, kwambara neza no kuringaniza. Ubusanzwe igikonjo gikozwe mubyuma biciriritse bya karubone, kandi hejuru yikinyamakuru bivurwa no kuzimya inshuro nyinshi cyangwa nitriding. Shanghai Santana moteri crankshaft ikozwe mubyuma byo mu rwego rwo hejuru byuma bya karubone bipfa guhimba. Moteri ya Audi JW na Yuchai YC6105QC ikozwe mubiciro bidahenze, imbaraga-zidasanzwe zidasanzwe zidasanzwe zidafite imbaraga zo kwihanganira kwambara.
1. Imiterere ya crankshaft
Ubusanzwe igikonjo kigizwe numutwe wimbere, ijosi nyamukuru ryizosi, igikonjo, kiremereye, ikinyamakuru gihuza inkoni numutwe winyuma. Igikonoshwa kigizwe nikinyamakuru gihuza ikinyamakuru hamwe n'ibumoso n'iburyo by'ibinyamakuru. Umubare wa crank ya shitingi biterwa numubare na gahunda ya silinderi. Crankshaft ya moteri imwe ya silinderi ifite igikona kimwe gusa; Umubare wa crank ya crankshaft ya moteri kumurongo ungana numubare wa silinderi; Umubare wimigozi muri crankshaft ya moteri ya V ingana na kimwe cya kabiri cyumubare wa silinderi. Urupapuro rwimbere rwimbere rwa crankshaft rufite pulley, ibikoresho byigihe, nibindi, bikoreshwa mugutwara pompe yamazi hamwe nuburyo bwa valve. Ijosi rya spindle ya crankshaft ryashyizwe mubyicaro bikuru byumubiri wa silinderi kandi bikoreshwa mugushigikira igikonjo. Ikinyamakuru gihuza ikinyamakuru gikoreshwa mugushiraho inkoni ihuza, kandi igikona gihuza ikinyamakuru nyamukuru cya shaft nikinyamakuru gihuza inkoni. Kugirango uringanize imbaraga za centrifugal mugihe igikonjo kizunguruka, impagarike itangwa kumurongo. Ihuza rya flange ritangwa kumpera yinyuma ya crankshaft kugirango uhuze isazi na crankshaft na bolts. Kugirango usige amavuta ikinyamakuru gihuza, igice cyo gusiga cyacukuwe kuva ikinyamakuru kinini cya shaft kugeza ikinyamakuru gihuza. Igice cya crankshaft kiroroshye muburyo bwubaka, urumuri muburemere kandi rwizewe mubikorwa, kandi mubisanzwe bifata ibyuma byoroshye, bikoreshwa cyane muri moteri yo hagati na nto.
2. Ihame ryimiterere ya crank
Imiterere ya crankshaft nu mwanya ugereranije na buri crank biterwa ahanini numubare wa silinderi, gahunda ya silinderi hamwe nakazi ka buri silinderi. Mugihe utegura moteri ikurikirana, amategeko akurikira agomba gukurikizwa uko bishoboka:
Kora silindiri ebyiri zumurimo uhoraho kure cyane ishoboka kugirango ugabanye umutwaro wingenzi, kandi wirinde ko habaho imibiri ibiri ihujwe ifungura icyarimwe mugihe cyo gufata, kandi ibintu byo "gufata ikirere" bigira ingaruka kumafaranga. imikorere ya moteri.
(1) Intera ikora Inguni ya buri silinderi igomba kuba ingana kugirango byorohereze imikorere ya moteri. Muri Angle ya crankshaft aho moteri irangirira kumurongo wakazi, buri silinderi igomba gukora rimwe. Kuri moteri enye ifite moteri ya silinderi i, intera y'akazi Inguni ni 720 ° / i. Ni ukuvuga, buri 720 ° / i ya crankshaft igomba kugira silinderi kumurimo kugirango moteri ikore neza.
(2) Niba ari moteri yubwoko bwa V, inkingi yibumoso n iburyo ya silinderi igomba guhinduranya akazi.
3. Ibisanzwe byinshi-silinderi ya moteri ya crank gahunda na gahunda yo gukora
Itondekanya rya crankshaft na crank ya moteri kumurongo wa moteri enye. Intera y'akazi Inguni y'umurongo wa silindari enye ya moteri enye ni 720 ° / 4 = 180 °, inkono enye zitondekanye mu ndege imwe, kandi moteri ikora (cyangwa ikurikiranye) ni 1-3- 4-2 cyangwa 1-2-4-3. Igikoresho gikora cyizunguruka gikunze gukoreshwa gifite uruhande rumwe rwumuzingi ruzengurutse icyuma hamwe na anti-friction icyuma, crankshaft nyamukuru ifite flanging na ring ring ring ifite uburyo butatu. Igikoresho cyo gusunika ni urupapuro rw'icyuma gifite impeta ya anti-friction igaragara hanze, igashyirwa mu gikingi cy'umubiri cyangwa igifuniko kinini. Kugirango wirinde kuzunguruka kwa pisine, igikonjo gifite igituba gifatanye muri ruhago. Amashanyarazi amwe akoresha ibice 4 kugirango agire imipaka ibiri myiza yumuzingi, kandi bamwe bakoresha ibice 2 byimbibi. Uruhande rufite ibyuma birwanya friction bigomba guhangana na crankshaft.
Zhuo Meng Shanghai Auto Co, Ltd. yiyemeje kugurisha MG & MAUXS ibice byimodoka ikaze kugura.
