Musiyano uripo pakati pecheni ye12B necheni ye12A

1. Mafomati akasiyana

Musiyano uripo pakati pecheni ye12B necheni ye12A ndewekuti cheni yeB ndeyehumambo uye inoenderana nezvinodiwa zveEurope (kunyanya zveBritain) uye inowanzo shandiswa munyika dzeEurope; cheni yeA inoreva metric uye inoenderana nezvinodiwa zvehukuru hwecheni yeAmerica uye inowanzoshandiswa muUnited States neJapan nedzimwe nyika.

2. Saizi dzakasiyana

Kureba kwecheni mbiri idzi i19.05MM, uye mamwe masayizi akasiyana. Chikamu chekukosha (MM):

12B cheni parameters: dhayamita yeroller i12.07MM, upamhi hwemukati mechikamu chemukati i11.68MM, dhayamita yepini shaft i5.72MM, uye ukobvu hwecheni plate i1.88MM;
12A cheni parameters: dhayamita yeroller i11.91MM, upamhi hwemukati mechikamu chemukati i12.57MM, dhayamita yepin shaft i5.94MM, uye ukobvu hwecheni plate i2.04MM.

3. Zvinodiwa zvakasiyana zvemagadzirirwo

Maketani eA series ane chiyero chakati kune maroller nemapini, ukobvu hweplate yemukati yecheni neplate yekunze yecheni zvakaenzana, uye simba rakaenzana resimba restatic rinowanikwa kuburikidza nekugadzirisa kwakasiyana. Zvisinei, hapana chiyero chiri pachena pakati pehukuru hukuru uye pitch yezvikamu zveB series. Kunze kwe12B specification iri pasi peA series, mamwe maspecification eB series akafanana nezvigadzirwa zveA series.
