Curved tooth couplings are suitable for large torque changes and forward and reverse working conditions, and have a good buffering effect, but the curved tooth shape is poor in manufacturability. Since the spring leaf is in point contact with the arc surface of the tooth, the coupling can obtain great flexibility and can be installed to work normally when there are radial, angular and axial deviations at the same time. There will inevitably be problems during use, and most of the problems that occur are vibration.

The curved tooth coupling has small radial size and large load capacity, and is often used for shaft transmission under low-speed and heavy-load conditions. The dynamically balanced tooth coupling can be used for transmission, such as the shaft transmission of gas turbines. Bearings and vibrations in all directions are dominated by power frequency, with relatively obvious double frequency components.

Couplings are suitable for the transmission connection between energy equipment and fans. They are mainly formed by unilateral half-couplings, sleeves and diaphragms between half-couplings. Double-flange couplings are suitable for two shaft ends with The long-distance and heavy-duty shaft connection can well compensate the different errors between the output shaft of the energy equipment side and the input shaft of the fan, and make the entire transmission system run stably.

The double flange coupling is one of the important transmission basic parts on the equipment. It is mainly used to connect the shafts of the two equipments to transmit torque and motion. It is mainly divided into rigid couplings and flexible couplings. We use Double flange coupling is a kind of flexible coupling. In the case of high torque and high speed, such as the energy equipment of high-speed trains, several components are output, which can withstand different types of parts.
