Material requirements and instructions for drum gear couplings

   　The internal structure of the drum gear coupling is very complicated, and the materials used can meet the requirements of torque and speed. Generally speaking, the commonly used materials are 42crmo and 45# steel forgings.These two materials are mainly used by themselves. The higher the hardness of the material, the greater the torque carried, and the longer the life of the coupling!

　　The 42Cr2Mo steel used in the drum gear coupling is a high-strength steel with strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue and toughness after quenching and tempering. Resistant to multiple impacts, good low-temperature impact toughness, and high creep strength at high temperatures.The steel usually uses surface quenching after quenching and tempering as a heat treatment plan
