Tsanangudzo uye kuumbwa kwechain drive

Chii chinonzi cheni drive?Chain drive inzira yekufambisa iyo inofambisa kufamba uye simba rekutyaira sprocket ine yakakosha mazino chimiro kune inofambiswa sprocket ine yakakosha mazino chimiro kuburikidza neketani.
Iyo ketani yekutyaira ine simba remutoro rakasimba (yakakwira inobvumidzwa tension) uye yakakodzera kutapurirana pakati pemashaft akaenzana pamusoro pemarefu marefu (mamita akati wandei).Inogona kushanda munzvimbo dzakaoma dzakadai sekupisa kwakanyanya kana kusvibiswa kwemafuta.Iyo ine yakaderera kugadzira uye kuisirwa kururama uye yakaderera mutengo.Nekudaro, iyo yekukurumidza kukurumidza uye yekutapurirana reshiyo yeketani drive haisi nguva dzose, saka kutapurirana hakuna kugadzikana uye kune imwe mhedzisiro uye ruzha.Inonyanya kushandiswa mumigodhi, zvekurima, peturu, mudhudhudhu / bhasikoro uye mamwe maindasitiri nemichina, uye nhamba huru yehardware, midziyo yemumba, uye maindasitiri emagetsi.Mutsara wekugadzira unoshandisawo kaviri-kumhanya maketani kutakura maturusi.
Iyo inonzi double speed chain ndeye roller chain.Iyo inofamba kumhanya V0 yeketani inoramba isina kuchinjika.Kazhinji, kumhanya kwe roller = (2-3) V0.

Zvigadzirwa zveotomatiki zvakajairika hazviwanzo shandisa madhiraivha emaketani, nekuti izvo zvinodikanwa zvekuremerwa pasi pemamiriro ekushanda zvakanyanya hazvina kukwirira, uye kusimbiswa kwakanyanya kunoiswa pakumhanya kukuru, kurongeka kwepamusoro, kuderera kwekuchengetedza, kuderera kweruzha, etc. Aya ndiwo kushaya simba kwemaketani ekutyaira.Kazhinji, iyo shaft yemagetsi yekutanga dhizaini dhizaini inotyaira michina yeakawanda masisitimu kuburikidza neketani kutapurirana.Iyi "axis imwe, akawanda mafambiro" emidziyo yemhando yemodhi inoita kunge ine zvehunyanzvi zvemukati, asi haina kufarirwa izvozvi (kusagadzikana kuchinjika, kusagadzikana gadziriso, yakakwirira dhizaini zvinodiwa), nekuti nhamba huru yezvishandiso mukati mebhizinesi inonyanya kushandisa pneumatic michina, uye nzira dzakasiyana-siyana Dzese dzine simba rakazvimirira (cylinder), uye mafambiro acho anogona kudzorwa nyore nyore kuburikidza nehurongwa.
Chii chinonzi chetani drive?
Chain drive inzira yekutapurirana iyo cheni inotumira simba kuburikidza ne meshing yema rollers uye mazino e sprocket.Zvikamu zvinosanganisirwa mucheni drive zvinosanganisira sprockets, cheni, idlers uye zvine hukama zvishongedzo (senge tension adjusters, cheni madhairekitori), ayo anogona kuchinjika akafananidzwa uye kuiswa zvinoenderana nemamiriro chaiwo.Pakati pavo, ketani inoumbwa nema rollers, mukati uye kunze mahwendefa, bushings, pini uye zvimwe zvikamu.

Izvo zvakakosha paramita yeketani drive haigone kuregererwa.
1. Pitch.Chinhambwe chiri pakati penzvimbo dzemarori maviri akatarisana pane cheni.Iyo yakakura mbiru, iyo yakakura saizi yezvikamu, izvo zvinogona kutumira simba repamusoro uye kutakura mitoro mikuru (yepasi-kumhanya uye inorema-inorema roller cheni kutapurirana, pitch inofanira kusarudzwa saizi yakakura).Kazhinji, iwe unofanirwa kusarudza cheni ine diki pitch ine inodiwa yekufambisa simba (kana mutsara wemutsara mumwe chete usina kukwana, unogona kusarudza akawanda-mitsara cheni) kuti uwane yakaderera ruzha uye kugadzikana.
2. Pakarepo kutapurirana reshiyo.Iyo yekukurumidza kutapurirana reshiyo yecheni drive ndeye i=w1/w2, uko w1 uye w2 ari kutenderera kumhanya kweiyo sprocket yekutyaira uye inotyairwa sprocket zvakateerana.ndinofanira kusangana nemamwe mamiriro (nhamba yemazino ezvipembenene zviviri zvakaenzana, uye kureba kweparutivi ndiko chaiko kwakazara kwenguva dzepitch), inogara iripo.
3. Nhamba yemazino epinion.Kuwedzera zvakafanira nhamba yemazino epinion kunogona kuderedza kusaenzana kwekufamba uye mitoro ine simba.
