Gears. Cylindrical involute gears and gear pairs. Concepts and geometry Ingestion-build-81111 BS EN 2684 specifies the1 Scope This International Standard specifies the geometric concepts and parameters for cylindrical gears with involute helicoid tooth flanks. Flank modifications are included. It also covers the concepts and parameters for cylindrical gear pairs with parallel axes and a constant gear ratio, which consist of cylindrical gears according to it. Gear and mating gear in these gear pairs have the same basic rack tooth profile. The equations given are not
