GB/T 12759-1991
ActiveDouble-circular-arc tooth profile of basic rack for cylindrical gears
双圆弧圆柱齿轮基本齿廓
Application Summary AI generated
This standard specifies the basic rack tooth profile geometry for cylindrical gears with double-circular-arc teeth, defining the precise dimensions and curvature of the tooth flanks. It is applied in the design and manufacturing of heavy-duty gear transmissions, such as those used in mining, cement mills, and marine propulsion systems, where high load capacity and improved contact fatigue resistance are required. The standard ensures interchangeability and consistent performance in industrial gearboxes operating under high torque and moderate speeds.
