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 thwala 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 ukungenisa 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.
