ActiveSynchronous belt drives—Curvilinear profile systems G、H、R and S belts and pulleys
同步带传动 G、H、R、S齿型曲线齿同步带与带轮
Application Summary AI generated
This standard specifies the dimensional characteristics, tooth profiles, and tolerances for curvilinear synchronous belts and pulleys in G, H, R, and S profiles. It is applied in the design and manufacturing of mechanical power transmission systems, particularly in automotive engines, industrial machinery, and precision equipment where high torque and synchronous motion are required. The standard ensures interchangeability and reliable performance between belts and pulleys from different manufacturers.
