Coupling materials are roughly divided into sections (round steel), castings (cast iron or cast steel), forgings, etc., and cast steel and forgings are most of the choices of coupling materials.
Due to various reasons, the center of mass or inertial principal axis of the diaphragm coupling does not coincide with the axis of rotation, and the phenomenon of unbalanced centrifugal inertial force, centrifugal inertial couple force and dynamic deflection (vibration shape) will occur during operation, which is called the phenomenon of rotor Imbalance.
Because hot-loading is performed under high temperature and stress, it is necessary to have sufficient estimates of possible problems and try to avoid them in advance. If it happens, you should also panic on the spot and take timely measures to deal with it.
Cast steel: Cast steel has poor mechanical properties and small applications. It is usually used to make large gears, large gear rings, etc. that cannot be forged!
Able to withstand large fleeing, such as different types of finished parts.
The diaphragm coupling bolt connection does not need to be threaded on the connecting piece, the use is not restricted by the connecting piece, the structure is simple, and the disassembly and assembly are convenient.
Coupling inspection is a key link related to installation, use and life. Reasonable inspection in accordance with inspection procedures will help provide working speed to avoid missed inspections and false inspections during production.
The plum coupling is processed by machining methods such as turning, milling, and broaching, and then undergoes overall heat treatment.
