Alignment: use a dial indicator to detect the runout of the end face and outer circle of the coil spring coupling. When the outer circle of the coil spring coupling is less than 250mm, the runout value should not exceed 005mm; when the outer circle of the flange plate is larger than 250mm, the runout value should be Should not be greater than 008.

Install the snake spring coupling: Insert the snake spring coupling from the outside of the small hole of the flange, and put it on the buffer sleeve, elastic washer, twist the nut from the outside of the large hole of the other flange, and use a wrench to Tighten the nut. If it is not suitable for installation or removal and replacement without damaging the shaft and half coupling of the spring coupling, please use the tools as shown in Figure 3 to Figure 7 and install it. After installation, it is better to rotate freely.

Notes to the operator of the snake spring coupling: Before starting the equipment, check whether the nut of the coupling is loose or falling off. If necessary, tighten the nut with a wrench in time. The equipment should be started with no load for 1 minute and then the valve of the load line should be opened; the shutdown sequence is reversed. (Please brush the outside of the snake spring coupling with oil once a month)

Practice has proved that if the installation, maintenance and operation are carried out according to the instructions and requirements, the number of daily starts of the snake spring coupling is 15 times, and the service life of the snake spring coupling is at least 5 years. If the installation and maintenance are not carried out according to the requirements of the manual , operation, especially if the bolts are installed in the wrong direction to deform the diaphragm or the two axes of the prime mover and the working machine are too large, the diaphragm will be damaged in advance.

The snake spring coupling is a mechanical part used to connect two shafts (driving shaft and driven shaft) in different mechanisms to rotate together to transmit torque. In high-speed and heavy-load power transmission, some snake spring couplings also have the functions of buffering, damping and improving the dynamic performance of the shaft system. The snake spring coupling consists of two halves, which are respectively connected with the driving shaft and the driven shaft. Most of the general power machines are connected with the working machine by means of a snake spring coupling. The elastic movable coupling (referred to as elastic coupling) uses the elastic deformation of the elastic element to compensate for the deflection and displacement of the two shafts, and the elastic element also has buffering and vibration damping properties, such as snake spring coupling, radial Multilayer leaf spring coupling, elastic ring pin coupling, nylon pin coupling, rubber sleeve coupling, etc. Snake spring couplings are somewhat standardized. When selecting, first select the appropriate type according to the work requirements, then calculate the torque and speed according to the diameter of the shaft, then find out the applicable model from the relevant manual, and finally make necessary checks on some key parts.
