Ko A uye B munhamba yeketani zvinorevei?

Kune maviri akatevedzana eA uye B munhamba yeketani.Iyo A nhevedzano ndiyo saizi yakatarwa inoenderana neAmerican chain standard: iyo B yakatevedzana ndiyo saizi yakatarwa inosangana neEuropean (kunyanya iyo UK) chain standard.Kunze kwechimiro chimwe chete, ivo vane maitiro avo mune mamwe maitiro.Misiyano mikuru ndeiyi:
1) Ukobvu hwemukati cheni cheni uye yekunze cheni ndiro yeA akateedzana zvigadzirwa zvakaenzana, uye yakaenzana simba mhedzisiro yeiyo static simba inowanikwa kuburikidza nekugadziriswa kwakasiyana.Iyo yemukati cheni ndiro uye yekunze cheni ndiro yeB yakatevedzana zvigadzirwa zvinogadziriswa kuti zvive zvakaenzana, uye iyo yakaenzana simba mhedzisiro yeiyo static simba inowanikwa kuburikidza neBaidu dzakasiyana.
2) Zviyero zvikuru zvechikamu chega chega cheA nhevedzano ine imwe reshiyo kune pitch.Zvakadai se: pini dhayamita = (5/16) P, roller dhayamita = (5/8) P, cheni yendiro ukobvu = (1/8) P (P ndiyo nhanho yeketani), nezvimwewo. Zvisinei, hapana reshiyo iri pachena. pakati pehukuru hukuru uye kukwirira kwezvikamu zveB zvakatevedzana.
3) Kuenzanisa kukosha kwekutyoka kwemaketani egiredhi rimwechete, kunze kwekunge iyo 12B yakatarwa yeiyo B yakatevedzana yakaderera pane iyo yeA nhevedzano, zvimwe zvese zvakatemwa zvakafanana neA akatevedzana zvigadzirwa zvegiredhi rimwechete. .

Chiyero chechigadzirwa chakaenzana nechiyero chepasi rose ISO9606: 1994, uye chimiro chayo chechigadzirwa, saizi uye kukosha kwekuremerwa zvinonyatsoenderana neyakajairwa pasi rose.
Zvimiro zvechimiro: Cheni inoumbwa nemukati cheni mahwendefa, rollers uye maoko, ayo akachinjika akasungirirwa necheni dzekunze, ayo anoumbwa nekunze cheni mahwendefa uye pini shafts.
Nekusarudzwa kwechigadzirwa, iyo inodiwa ketani yakatarwa inogona kusarudzwa maererano nemagetsi curve.Kana yakasarudzwa zvinoenderana nekuverenga, iyo yekuchengetedza chinhu inofanira kunge yakakura kupfuura 3.
