I-Genuine Original camshaft eyakhiwe ngezingxenye zemoto ye-cherry

I-camshaft adjuster iyi-valve yokulawula ukuphambuka kwe-cam, okuyi-valve ye-stroke ekhoneni, eyakhiwe i-activator kagesi ekhoneni kanye ne-eccentric hemispherical valve.I-actuator yamukela isakhiwo esihlanganisiwe, futhi i-actuator kagesi inesistimu ye-servo eyakhelwe ngaphakathi.

Isimiso: Shintsha isikhathi sokuvula sama-valve okungenisa nawokukhipha ngokuvumelana nezidingo zokusebenza zenjini.Lapho injini ingaphansi komthwalo omkhulu, isilungisi se-camshaft sisetshenziselwa ukwandisa i-valve overlap angle ngokuya ngesivinini senjini, ukuze inikeze umoya ohlanzekile omningi ekamelweni elivuthayo ngangokunokwenzeka, ukuze kuzuzwe amandla aphezulu kanye ne-angle egqagqene, ukuze unikeze igumbi elivuthayo ngangokunokwenzeka Umoya ohlanzekile ukuze uzuze amandla aphezulu kanye netorque.

I-camshaft iyingxenye yenjini ye-piston.Umsebenzi wawo ukulawula ukuvulwa nokuvalwa kwama-valve.Nakuba ijubane le-camshaft enjinini ye-stroke emine liyingxenye ye-crankshaft (ijubane le-camshaft enjinini enama-stroke amabili liyafana nele-crankshaft), ngokuvamile ijubane layo lisephezulu kakhulu futhi kudingeka phatha itorque enkulu.Ngakho-ke, umklamo unezidingo eziphakeme zamandla nokusekelwa kwendawo ye-camshaft, futhi impahla yayo ngokuvamile iyinsimbi ephezulu ye-alloy noma i-alloy steel.Ngenxa yokuthi umthetho wokunyakaza kwe-valve uhlobene namandla nezici zokusebenza zenjini, ukwakheka kwe-camshaft kudlala indima ebaluleke kakhulu enqubweni yokwakhiwa kwenjini.
Umzimba oyinhloko we-camshaft iyinduku ye-cylindrical cishe ngobude obufana ne-cylinder bank.Amakhamera amaningana anemikhono kuwo ukuze ashayele ivalvu.I-camshaft isekelwa emgodini ophethe i-camshaft ngokusebenzisa ijenali ye-camshaft, ngakho inani lamajenali e-camshaft liyisici esibalulekile esithinta ukuqina kokusekelwa kwe-camshaft.Uma ukuqina kwe-camshaft kunganele, ukuguqulwa kokugoba kuzokwenzeka ngesikhathi sokusebenza, okuthinta isikhathi se-valve.
Uhlangothi lwekamela lumise okweqanda.Iklanyelwe ukuqinisekisa ukungena okwanele kanye nokuphuma kwe-cylinder.Ngaphezu kwalokho, uma kucatshangelwa ukuqina nokusebenza kahle kwe-injini, i-valve ayikwazi ukuba nomthelela omkhulu ngenxa yenqubo yokusheshisa nokunciphisa izinga ekuvuleni nasekuvaleni isenzo, ngaphandle kwalokho kuzodala ukuguga okukhulu kwe-valve, ukwanda komsindo noma okunye okubucayi. imiphumela.Ngakho-ke, ikhamera ihlobene ngokuqondile namandla, ukuphuma kwe-torque nokusebenza kahle kwenjini.
Amaphutha avamile e-camshaft ahlanganisa ukuguga okungavamile, umsindo ongavamile nokuphuka.Ukuguga okungavamile kuvame ukwenzeka ngaphambi komsindo ongavamile nokuphuka.
(1) I-camshaft isicishe ibe sekupheleni kwesistimu yokugcoba injini, ngakho-ke isimo sokuthambisa asinalo ithemba.Uma ingcindezi yokunikezwa kwamafutha ephampu kawoyela inganele ngenxa yesikhathi eside sesevisi, noma uwoyela wokugcoba awukwazi ukufinyelela ku-camshaft ngenxa yokuvinjelwa kwephaseji likawoyela wokugcoba, noma uwoyela wokugcoba awukwazi ukungena ku-camshaft imvume ngenxa ye-torque yokuqina ngokweqile. we-fastening bolts of the bearing cover, i-camshaft izobe igqoke ngendlela engavamile.
(2) Ukuguga okungavamile kwe-camshaft kuzokwandisa igebe phakathi kwe-camshaft nesihlalo esinesihlalo, futhi i-camshaft izohamba nge-axially, kubangele umsindo ongavamile.Ukuguga okungavamile kuzophinde kwandise igebe phakathi kwekhamera yokushayela kanye ne-hydraulic tappet, futhi ikhamera izoshayisana ne-hydraulic tappet, kubangele umsindo ongajwayelekile.
(3) Ngezinye izikhathi kwenzeka amaphutha angathi sína njengokuphuka kwe-camshaft.Izimbangela ezivamile ukuhlukana kwe-tappet ye-hydraulic noma ukuguga okukhulu, ukugcotshwa okubi kakhulu, izinga eliphansi le-camshaft kanye nokuphuka kwegiya le-camshaft lesikhathi.
(4) Kwezinye izimo, ukwehluleka kwe-camshaft kubangelwa izici zomuntu, ikakhulukazi lapho i-camshaft ingahlakazwa ngendlela efanele ngesikhathi sokugcinwa kwenjini.Isibonelo, lapho ukhipha ikhava yokufaka i-camshaft, yingqongqoze ngesando noma uyicwecwe nge-screwdriver, noma ufake isembozo sokuthwala endaweni engafanele, okuholela ekungafanini phakathi kwekhava yokuthwala nesihlalo esiphethe, noma i-torque eqinisayo. amabhawodi okubopha wekhava yokuthwala makhulu kakhulu.Lapho ufaka isembozo esithwalayo, naka umcibisholo wesiqondiso, inombolo yesikhundla kanye namanye amamaki ebusweni bekhava elithwalayo, futhi uqinise amabhawodi okubopha wekhava elithwala ngesikrufu se-torque ngokuhambisana ngokuqinile ne-torque eshiwo.
