GB/T 18842-2008

GB/T 18842-2008 specifies the dimensions, tolerances, and inspection methods for taper cylindrical involute splines, which are used in mechanical transmission systems requiring high torque capacity and precise axial positioning. This standard is applied in the design and manufacturing of automotive drivetrains, heavy machinery gearboxes, and aerospace components where splined connections must withstand variable loads and maintain alignment under angular misalignment. It ensures interchangeability and reliability of splined joints in applications like steering columns, power take-offs, and rotor hubs.
