Ukwakhiwa kwe-hydraulic tensioner
I-tensioner ifakwe ohlangothini olukhululekile lwesistimu yesikhathi, esekela kakhulu ipuleti lokuqondisa lesistimu yesikhathi futhi isuse ukudlidliza okubangelwa ukushintshashintsha kwejubane le-crankshaft kanye nomphumela we-polygon ngokwawo. Isakhiwo esijwayelekile siboniswe kuMfanekiso 2, ohlanganisa kakhulu izingxenye ezinhlanu: igobolondo, i-check valve, i-plunger, i-plunger spring kanye ne-filler. Uwoyela ugcwaliswa ekamelweni lokucindezela okuphansi kusuka endaweni yokungena uwoyela, bese ugeleza ungene ekamelweni lokucindezela okuphezulu elakhiwe yi-plunger kanye negobolondo nge-check valve ukuze kutholakale ingcindezi. Uwoyela ekamelweni lokucindezela okuphezulu ungavuza ngethangi likawoyela elimanzi kanye negebe le-plunger, okuholela emandleni amakhulu okumanzisa ukuqinisekisa ukusebenza kahle kwesistimu.
Ulwazi lwangemuva 2: Izici zokudambisa i-hydraulic tensioner
Uma kusetshenziswa i-harmonic displacement excitation ku-plunger ye-tensioner ku-Figure 2, i-plunger izokhiqiza amandla okunciphisa osayizi abahlukene ukuze inciphise ithonya le-external excitation ohlelweni. Kuyindlela ephumelelayo yokufunda izici ze-tensioner ukukhipha idatha yamandla kanye ne-displacement ye-plunger bese udweba i-damping characteristic curve njengoba kuboniswe ku-Figure 3.
Ijika eliyisici sokudambisa lingabonisa ulwazi oluningi. Isibonelo, indawo evalekile yejika imelela amandla okudambisa asetshenziswa yi-tensioner ngesikhathi sokunyakaza okuvamile. Uma indawo evalekile inkulu, kulapho amandla okumunca ukudlidliza eqina khona; Esinye isibonelo: ukuthambeka kwejika lesigaba sokucindezela kanye nesigaba sokusetha kabusha kumelela ukuzwela kokulayisha nokukhulula i-tensioner. Uma ukulayisha nokukhulula ngokushesha, kulapho ukuhamba okungalungile kwe-tensioner kuncipha, futhi kuzuzisa kakhulu ukugcina ukuzinza kwesistimu ngaphansi kokuhamba okuncane kwe-plunger.
Ulwazi lwangemuva 3: Ubudlelwano phakathi kwamandla e-plunger kanye namandla axegayo e-chain
Amandla onqenqema olukhululekile lweketanga ukuwohloka kwamandla okucindezela kwe-tensioner plunger eceleni kwendlela eqondile yepuleti lomhlahlandlela we-tensioner. Njengoba ipuleti lomhlahlandlela we-tensioner lijikeleza, indlela eqondile iyashintsha ngasikhathi sinye. Ngokusho kohlelo lwesikhathi, ubudlelwano obuhambisanayo phakathi kwamandla e-plunger kanye namandla onqenqema olukhululekile ngaphansi kwezikhundla ezahlukene zepuleti lomhlahlandlela bungaxazululwa cishe, njengoba kuboniswe kuMfanekiso 5. Njengoba kungabonakala kuMfanekiso 6, indlela yokushintsha kwamandla onqenqema olukhululekile kanye nendlela yokushintsha kwamandla e-plunger esigabeni sokusebenza iyafana ngokuyisisekelo.
Nakuba amandla aseceleni aqinile angeke atholakale ngqo yi-plunger force, ngokusho kokuhlangenwe nakho kobunjiniyela, amandla aseceleni aqinile aphezulu cishe aphindwe izikhathi ezingu-1.1 kuya kwezingu-1.5 kune-free side force ephezulu, okwenza kube nokwenzeka ngonjiniyela ukubikezela ngokungaqondile amandla aphezulu eketanga lesistimu ngokutadisha amandla e-plunger.
