適用范圍

1.1.1 This Standard covers requirements for squareand rectangular parallel keys and keyways intended forboth alignment of shafts and hubs, and transmittingtorque between shafts and hubs. 1.1.2 Keys covered by this Standard have a relativelyloose width tolerance. All width tolerances arepositive. Keys with minus width tolerances and a smallertolerance range are covered by ASME B 18.25.lM. 1.1.3 The inclusion of dimensional data in thisStandard is not intended to imply that all sizes describedare production stock items. Consumers should consultwith suppliers concerning lists of stock items. 1.1.1 本標(biāo)準(zhǔn)涵蓋了用于軸和輪轂對(duì)中以及在軸和輪轂之間傳遞扭矩的方形和矩形平行鍵和鍵槽的要求。
1.1.2 本標(biāo)準(zhǔn)涵蓋的密鑰具有相對(duì)寬松的寬度公差。所有寬度公差均為正。具有負(fù)寬度公差和較小公差范圍的鍵由 ASME B 18.25.lM 涵蓋。
1.1.3 本標(biāo)準(zhǔn)中包含尺寸數(shù)據(jù)并不意味著所有尺寸都描述了生產(chǎn)庫(kù)存項(xiàng)目。消費(fèi)者應(yīng)就庫(kù)存物品清單向供應(yīng)商咨詢。
