Several matters needing attention when adjusting the coupling

　　(1) If the concentricity of the coupling is tested before the anchor bolts are tightened, there is no need to rush to remove the measuring tool after adjustment.Because in the process of tightening the anchor bolts, due to improper tightening method, or the shim near the anchor bolts are not really supported, etc., the installation accuracy after tightening will change.It is generally required to check again after tightening, or check while tightening, to ensure the concentricity of the two shafts.
　　(2) When installing on site, due to conditions, the pad irons used to adjust the level are mostly iron plates with different thicknesses.When in use, clean the burrs, welding slag and other debris on the edge of the iron plate to prevent the debris from breaking due to vibration and other reasons after the adjustment of the parts, the shim support is not strong, the parts sink or the position changes , So that the concentricity of each coupling changes, causing the equipment installation accuracy to fail to meet the requirements.Generally, after the adjustment meets the requirements, the pad iron is welded into a whole.
　　(3) When installing, first install the roller components, and then use the roller spindle as the reference axis to measure the concentricity between the output shaft of the reducer and the roller spindle.After the reducer components are adjusted to meet the requirements, the concentricity of the motor shaft is measured with the input shaft of the reducer as the reference axis.However, because the brake wheel coupling is installed on the input shaft of the reducer, the motor and brake are installed on the motor base.Before adjusting the motor shaft, take the brake wheel as the reference, and adjust the concentricity of the motor shaft and the input shaft of the reducer after adjusting the brake shoe on the brake.
