Kuvaka hydraulic tensioner
Chinovhara tensioner chakaiswa parutivi rwakasununguka rwetiming system, icho chinonyanya kutsigira gwara rekutungamira retiming system uye chinobvisa kudedera kunokonzerwa nekuchinja-chinja kwe crankshaft uye polygon effect yacho pachayo. Chimiro chakajairika chinoratidzwa muMufananidzo 2, icho chinonyanya kusanganisira zvikamu zvishanu: shell, check valve, plunger, plunger spring uye filler. Oiri inozadzwa mukamuri ine low pressure kubva muoil inlet, uye inoyerera mukamuri ine pressure yakakwira inoumbwa neplunger ne shell kuburikidza necheck valve kuti ione kuti pressure yacho iri kupi. Oiri iri mukamuri ine pressure yakakwira inogona kubuda nepatangi re damping oil uye plunger gap, zvichikonzera simba guru re damping kuti ive nechokwadi chekuti system inofamba zvakanaka.
Ruzivo rwemashure 2: Hunhu hwe hydraulic tensioner inonyorovesa mvura
Kana kufambiswa kwesimba kwesimba remagetsi (harmonic displacement excitation) kwaiswa pakuisa tensioner muFigure 2, kuisa tensioner kunogadzira simba rekudzivirira simba rehukuru hwakasiyana kuti kuvhare simba rekunze kwesimba remagetsi pasystem. Inzira inoshanda yekudzidza hunhu hwe tensioner kuti ubvise simba uye data rekuchinja kwe tensioner uye kudhirowa damping characteristic curve sezvakaratidzwa muFigure 3.
Kavha ine hunhu hwekunyorovesa inogona kuratidza ruzivo rwakawanda. Semuenzaniso, nzvimbo yakavharirwa yekavha inomiririra simba rekunyorovesa rinodyiwa ne tensioner panguva yekufamba kwenguva nenguva. Nzvimbo yakavharirwa yakakura, simba rekunyorovesa re vibration rinosimba; Mumwe muenzaniso: kutsveyama kwekavha yechikamu chekudzvanya uye chikamu chekugadzirisazve zvinomiririra kunzwa kwekurodha nekuburitsa tensioner. Kutakura nekuburitsa nekukasira, kufamba kusina kunaka kwe tensioner kushoma, uye zvinobatsira zvikuru kuchengetedza kugadzikana kwesystem pasi pekufambiswa kudiki kwe plunger.
Ruzivo rwekutanga 3: Hukama huripo pakati pesimba replunger nesimba recheni rakareruka
Simba rekuregedzera recheni ndiko kuputsika kwesimba rekutenderedza re tensioner plunger richitevedza gwara rekutenderedza re tensioner guide plate. Sezvo tensioner guide plate ichitenderera, gwara rekutenderedza rinochinja panguva imwe chete. Zvichienderana nehurongwa hwenguva, hukama hunoenderana pakati pe plunger force ne loose edge force pasi penzvimbo dzakasiyana dze guide plate hunogona kugadziriswa, sezvakaratidzwa muMufananidzo 5. Sezvatinoona muMufananidzo 6, mafambiro ekuchinja kwesimba rekuregedzera uye plunger force muchikamu chekushanda akafanana.
Kunyangwe simba reparutivi rakamanikana risingawanikwe zvakananga nesimba replunger, zvichienderana neruzivo rweinjiniya, simba reparutivi rakamanikana rinopetwa ka1.1 kusvika 1.5 kupfuura simba reparutivi rakamanikana, izvo zvinoita kuti mainjiniya akwanise kufanotaura zvisina kunanga simba reparutivi rakamanikana resystem nekudzidza simba replunger.
