Chii chinonzi chain drive? Chain drive inzira yekutumira inotumira kufamba nesimba re driving sprocket ine chimiro chezino chakakosha ku driving sprocket ine chimiro chezino chakakosha kuburikidza necheni.
Cheni yekufambisa ine mutoro wakasimba (kumanikidzwa kwakanyanya kunobvumirwa) uye yakakodzera kutakurwa pakati pemashaft akafanana munzvimbo refu (mamita akati wandei). Inogona kushanda munzvimbo dzakaoma dzakadai sekusvibiswa kwekupisa kwakanyanya kana mafuta. Ine kurongeka kwakaderera kwekugadzira nekuisa uye mutengo wakaderera. Zvisinei, kumhanya nekukurumidza uye chiyero chekutumira cheni yekufambisa hachichinji, saka kutakurwa kwacho hakuna kugadzikana uye kune ruzha rwakati. Inonyanya kushandiswa mumigodhi, kurima, peturu, midhudhudhu/mabhasikoro nedzimwe nzvimbo nemishini, uye huwandu hwakawanda hwemidziyo, midziyo yemumba, uye maindasitiri emagetsi. Mutsetse wekugadzira unoshandisawo cheni dzinomhanya kaviri kutakura maturusi.
Chinonzi cheni inomhanyisa kaviri icheni inotenderera. Kumhanya kweV0 cheni hakuchinji. Kazhinji, kumhanya kwerori = (2-3) V0.
Midziyo yemagetsi inowanzo shandiswa otomatiki haiwanzo shandisi madhiraivha echeni, nekuti zvinodiwa pakukwanisa kutakura zvinhu pasi pemamiriro ekushanda akajairika hazvina kukwira, uye kusimbiswa kwakanyanya kunoiswa pakumhanya kwakanyanya, kunyatsoita zvinhu nemazvo, kugadzirisa kwakaderera, ruzha rwakaderera, nezvimwewo. Izvi ndizvo zvinokanganisa madhiraivha echeni. Kazhinji, simba remuchina wekugadzira michina yekutanga rinofambisa michina yemichina yakawanda kuburikidza nekutumira cheni. Iyi modhi yemichina ye "one axis, multiple movements" inoita kunge ine zvehunyanzvi, asi haisi kufarirwa pari zvino (kusachinjika kwakashata, kugadzirisa kusina kunaka, zvinodiwa pakugadzira zvakanyanya), nekuti huwandu hwakawanda hwezvishandiso mukati mebhizinesi zvinonyanya kuve michina yepneumatic, uye michina yakasiyana-siyana Yese ine simba rakazvimirira (cylinder), uye kufamba kunogona kudzorwa nyore nyore kuburikidza nekugadzira mapurogiramu.
Chii chinonzi chain drive?
Kufambisa chain inzira yekutumira simba iyo chain inotumira simba kuburikidza nemeshing yemaroller nemazino e sprocket. Zvikamu zvinobatanidzwa mukufambisa chain zvinosanganisira ma sprockets, macheni, ma idlers nezvimwe zvinoshandiswa (zvakadai se tension adjusters, chain guides), izvo zvinogona kuenzaniswa uye kushandiswa zvinoenderana nemamiriro ezvinhu chaiwo. Pakati pazvo, chain ine ma rollers, ma plate emukati nekunze, bushings, pini nezvimwe zvikamu.
Zvikamu zvakakosha zvechain drive hazvigone kuregeredzwa.
1. Kukwira kwenzvimbo. Kureba pakati penzvimbo dzemaroller maviri ari pedyo pacheni yeroller. Kukwira kwenzvimbo, kukura kwezvikamu, zvinogona kutakura simba rakawanda uye kutakura mitoro yakakura (yekutumira maroller chain ane kumhanya kushoma uye mutoro unorema, kukwira kwenzvimbo kunofanira kusarudzwa saizi yakakura). Kazhinji, unofanirwa kusarudza cheni ine kukwira kushoma ine simba rekutumira rinodiwa (kana cheni yemutsara mumwe isina kugona kwakakwana, unogona kusarudza cheni yemutsara yakawanda) kuti uwane ruzha rwakaderera uye kugadzikana.
2. Chiyero chekutumira pakarepo. Chiyero chekutumira pakarepo chechain drive i=w1/w2, apo w1 na w2 ndiwo kumhanya kwekutenderera kwesprocket yekutyaira uye sprocket inotyairwa zvichiteerana. i inofanira kusangana nemamiriro akati wandei (huwandu hwemazino emasprocket maviri hwakaenzana, uye kureba kwedivi kwakasimba ndiko kwakaenzana nenhamba yenhamba yenguva dzekupidigura), inguva isingachinji.
3. Huwandu hwemazino epinion. Kuwedzera mazino epinion zvakakodzera kunogona kuderedza kusaenzana kwemafambiro uye mutoro unoshanduka.
