This standard specifies the structural type, main dimensions and technical requirements of H-shaped elastic block couplings. This standard is applicable to couplings that connect two coaxial transmission shaft systems and have certain capabilities of compensating the relative displacement of the two axes and buffering and damping properties. The operating temperature is -30~80℃, and the nominal transmission torque is 18~62N·m.
