After the coupling has been used for a period of time, it should be inspected and maintained regularly to reduce unnecessary damage.
1. Check the coupling body for cracks;
2. Check whether the key connection of the coupling is loose or rolling;
3. Check whether the lubrication condition of the coupling is good;
4. Check the complete condition, wear condition of the coupling gear and the meshing condition of the internal and external gears;
5. Whether the coupling connection is tight and firm;
6. Check whether there is radial circle runout and end face runout when the coupling rotates.
