The characteristics and requirements of gear couplings (XNUMX)

Author: admin Published: 2020-11-19

    The internal structure of the gear coupling is very messy, and the materials used have certain requirements to 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 to resist abrasion by themselves. The higher the hardness of the material, the better the resistance to abrasion. The greater the torque carried, the longer the service life of the coupling!Gear couplingThe 42Cr2Mo steel used is an ultra-high-strength steel with high strength and toughness, good hardenability, no obvious temper brittleness, small deformation during quenching, and high fatigue resistance after quenching and tempering. , Low-temperature impact toughness, high creep strength and long-term resistance at high temperature.The steel usually uses surface quenching after quenching and tempering as a heat treatment plan!Gear couplings transmit torque by connecting two front and back teeth and a central tube in series. If the distance between the motor and the reducer is too long, this type of coupling is used instead.Does the length of the central tube of the gear coupling have an effect on the torque? The gear coupling transfers torque by connecting two front and rear teeth and a central tube in series. If the distance between the motor and the reducer is too long, it is specially used. Replace this type of coupling.
