JB/T 7684-2007 (English Version) PDF

Scope: This standard specifies the type, size, basic parameters, technical requirements and inspection rules of LAK saddle block elastic coupling (coupling for short). This standard applies to transmission shaft systems connecting two coaxial lines. It has certain radial, axial and angular compensation and shock absorption properties. The ambient temperature is -20℃～+80℃, and the nominal transmission torque is 63N·m～50000N·m.
