Coupling shaft hole and connection size

Shaft transmission usually consists of one or severalCouplingConnect the main and driven shafts to form a 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.

  In the structural design and series design of various types of couplings, based on the size of the transmission torque, the structure of the coupling and the strength of the hub, determine the shaft hole range of the coupling of each specification (the largest and the smallest shaft Hole) and the length of the shaft hole, each specification has only one length of the shaft hole.In foreign countries, no matter which country, all the companies that produce couplings have the only shaft hole length of each specification in the standards of different couplings.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, multiple types are also added. The length of the shaft hole seems to be the only way to be completely transformed.
