Shaft hole and connection size

Various formsCouplingIn the structural design and series design, based on the size of the transmission torque, the structure of the coupling and the strength of the hub, determine the shaft hole range (largest and smallest shaft hole) and the length of the shaft hole of the coupling of each specification , Each specification has only one shaft hole length! In foreign countries, no matter which country all the coupling manufacturers in different coupling standards, it is the only shaft hole of each specification length.Due to the misleading of GB/T3852, each specification in the coupling product standard of our country corresponds to the length of the shaft hole with the change of the shaft hole. When the foreign coupling standard is converted into the Chinese standard, it is also added. The length of the shaft hole, it seems that only this is the complete conversion!

      Shaft transmission system to transmit rotation or movement.The coupling is mainly due to the shaft connection of the motor, the reducer and the working machine. The shaft hole form, connection form and size mainly depend on the type and size of the connected shaft. The product design is generally based on the cylindrical and conical shaft depth. Standard design shaft, shaft depth standard is for shaft design.
