Installation of serpentine spring coupling

① Install the seal ring and half shaft sleeve

Installation of shaft sleeve seal ring of serpentine spring coupling

At the beginning, we must turn off the startup power supply, wipe the coupling and the two connected shafts, and then apply grease on the half coupling and the seal ring (see the figure, put the seal ring on the shaft first). The cold installed quick installed coupling does not need to be heated, and the interference fit needs to be heated for installation.

② Alignment of two coupling halves

Use a ruler to measure the clearance, alignment and coaxiality of the two shaft sleeves, and adjust the deviation to the allowable range of coupling installation, including angle deviation, parallel deviation and floating deviation. Only when the coupling is correctly aligned, can the long service life of Z and the maintenance of the coupling with small Z be achieved.

③ Installation of serpentine spring

Before installing the serpentine spring, we shall fill the groove between the coupling teeth with long-term lubricating oil, then buckle the spring into the coupling tooth groove, and gently tap it in with a wooden hammer (note that all the fractures of the installed spring face the same direction to facilitate the correct contact of the stop block on the housing). Then scrape the grease out of the overflow spring. Generally, oil shall be added once half a year.

④ Installation of coupling housing

The serpentine spring first places the coupling seal ring at a suitable position on the shaft sleeve, then inserts it into the groove of the lower half shell, installs the gasket, and then installs the upper half shell, closes it, and tightly assembles it with screws. After the installation is completed, check again, and confirm that all components are correctly installed, the coupling is closely connected with the shaft, and an oil plug is installed in the oil injection hole before the formal work of the coupling.
