The installation method of the figure-eight coupling is as follows:
1. Calculate the required compensation amount based on the radial dimensions of the two connected shafts.
2. Select a suitable keyway coupling sleeve according to the calculated compensation amount, and its concentricity with the two connected axes should be within 0.05mm.
3. Check whether the keyway is suitable (including outer diameter size and end face shape). If it is not suitable, it should be trimmed.
4. Use a dial indicator to measure the verticality deviation of the two end surfaces should not be greater than 0.02mm/m.
5. Install the selected keyway into the shell, and make its axis parallel to or coincident with the center line of the inner hole of the shell
6. Use a feeler gauge to check whether the keyway is There is debris clogging.
7. After screwing in the nut, turn the bearing seat by hand so that the bearing seat can rotate freely.
