This standard is applicable to the transmission shaft system connecting two coaxial lines, which can limit torque and provide safe overload protection. The ambient temperature is -20+70C: the running torque is 0.315~8000kN·m. 2 Reference standards GB3507 GB3852 GB3931 GB4879 GB6388 GB7284 Packaging, storage and transportation pictorial signs Nominal torque series of mechanical couplings Types and dimensions of coupling shaft holes and keyways Terms of mechanical couplings Rust-proof packaging Transport packaging delivery and receipt signs Frame wooden boxes General technical requirements for packaging of electromechanical products GB/T 13384 JB3963 JB3965 Ultrasonic flaw detection of pressure vessel forgings Magnetic particle flaw detection of steel pressure vessels Sliding torque T The torque transmitted by the relative sliding moment of the driving and driven ends of the safety coupling, 4 categories There are seven types of safety couplings as follows, see Table 1.
