Each coupling should have a protective device to close the coupling and the shaft to prevent people or objects from entering this dangerous area when the unit is running.The protective device should be easily disassembled so as not to affect the connected machine when the coupling is overhauled and maintained.The structure of the protective device must have sufficient rigidity. When bearing a static load of 900N, its deflection shall not exceed 0.0005 times the unsupported length of the protective device.The protective device of the coupling that needs lubrication should be sealed.When necessary, the protective device should be equipped with anti-movement baffle to reduce the influence of gas or oil.Flange-connected cylindrical shell guards are usually used on medium and high-speed gear couplings and diaphragm couplings.
The structure of the protective device is cylindrical and split along the axial direction, and the protective device is connected to the corresponding equipment in the unit by flanges at both ends.There should be an expansion joint at one end of the protective device, and an O-ring seal should be installed at the expansion joint.If the coupling is working under corrosive conditions and needs protection, the protective device must be equipped with pipe joints to allow access to dry air or inert gas.Protective device for continuous lubrication of the controller.Each fuel injection nozzle must be screwed to the protective device in the appropriate direction, so that the oil sprays in the direction of rotation.If the unit is running in forward and reverse directions, the oil will be injected along the axial direction.The oil nozzle or oil pipe is not allowed to rub against the coupling.
