High speed Normal operation Flexible Disc Coupling for petroleum machinery

Transmission system of Flexible Disc Coupling shafting: Shafting transmission usually connects the main and driven shafts by one or several diaphragm couplings to form a shafting transmission system to transmit rotation or motion. Flexible Disc Coupling is mainly due to the shaft connection of the motor, reducer and working machine. Its 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 cylindrical and conical shaft depths. Standard design shaft, shaft depth standard is for shaft design. In the structural design and series design of various forms of metal Flexible Disc Coupling, the shaft hole range (maximum) of the metal diaphragm coupling is determined based on the size of the transmission torque, the structure of the Flexible Disc Coupling and the strength of the hub. and the minimum shaft hole) and the length of the shaft hole, each specification has only one shaft hole length.
