The torque is transmitted by inserting the serpentine spring into the groove of the two half couplings. The serpentine spring is inserted into the groove of the two half couplings to realize the connection between the driving shaft and the driven shaft. During the operation of the serpentine spring coupling, the driven end is driven by the axial force of the driving end teeth to transmit torque to the serpentine spring, thus avoiding resonance to a large extent. The centrifugal force generated during high-speed operation will spray oil into the meshing part of the internal and external teeth to make them fully lubricated. In order to prevent corrosion, this phenolic resin is usually used to make half coupling.

The degree of disassembly of the serpentine spring coupling is generally determined by the maintenance requirements. Some require that the two shafts connected be separated, some require that the coupling be completely disassembled, and the hub be removed from the shaft. From the power machine to work, the main and driven ends are connected by one or several serpentine spring couplings of different varieties or different types and specifications to form a shafting transmission system. Due to the different working principles and structures of power machines, their mechanical characteristics vary greatly. Some operate smoothly and some have impact during operation, which has different effects on the transmission system.

The mechanical characteristics vary greatly, some operate smoothly and some have impact during operation, which has different effects on the transmission system. Generally, the short time load shall not exceed twice of the nominal torque. The assembly process is to assemble the snake-spring coupling according to the assembly requirements, so that the snake-spring coupling can transmit the torque safely and reliably. Disassembly is generally due to equipment failure or the coupling itself needs to be repaired, and the serpentine spring coupling is disassembled into parts. The space in the flange plate is small, so it is difficult to remove the spring plate of the serpentine spring coupling.
