Coupling may consider what specific choice?
You may consider the following specific choice:
1) the size and nature of the required torque transmission and damping function of buffering requirements. For example, heavy-duty power transmission, the choice of gear coupling; severe shock loads or require the elimination of drive shaft torsional vibration, the choice of tire type couplings having a high elastic coupling.
2) the level of coupling operating speed and centrifugal force caused by the size. For high-speed shaft, the balance should be used in high precision couplings, such as a diaphragm couplings, etc., but should not use the presence of eccentric slider couplings.
3) two-axis size and direction of the relative displacement. After installation and adjustment, it is difficult to maintain a strict two-axis precision alignment, or work during two additional axes will have a greater relative displacement, flexible couplings should be used. For example, when large radial displacement, optional Oldham coupling, the angular displacement of the two axes intersect larger or optional universal connection couplings.
4) coupling reliability and working environment. Usually no lubrication of the coupling of a metal element made this more reliable; couplings require lubrication, lubrication performance vulnerable to the impact of the degree of perfection, and may pollute the environment. Coupling rubber and other non-metallic element contained in the temperature, corrosive media and other more sensitive to light, and easy to aging.
5) coupling manufacturing, installation, maintenance and costs. Under the premise of performance to meet it, it should be used to facilitate assembly and disassembly, easy maintenance, low cost of coupling. Such as a rigid coupling not only simple in structure, and easy assembly and disassembly, it can be used for low-speed, rigid shaft. General non-metallic elastic element coupling (such as an elastic sleeve pin coupling, flexible pin coupling, plum-shaped flexible coupling, etc.), due to good comprehensive ability, widely used in general, the small power transmission.
