ActiveInjection molding plastic cylindrical gears tolerance classification system—Definitions and allowable values of deviations relevant to flanks of gear teeth & double flank radial composite test
注射成型塑料圆柱齿轮精度制 轮齿同侧齿面偏差和径向综合偏差的定义和允许值
Application Summary AI generated
This standard defines a tolerance classification system for injection-molded plastic cylindrical gears, specifying allowable values for deviations on gear tooth flanks and for double flank radial composite testing. It is applied in the design, manufacturing, and quality inspection of plastic gears used in industries such as automotive, consumer electronics, and small appliances, where precise gear performance is critical. The standard provides a basis for ensuring consistent gear quality and interchangeability in mass production contexts.
