5 ways to choose the right coupling

The following is Botou XINLAN coupling for you to analyze how to choose the right oneCouplingMethods:
1 The reliability and working environment of the coupling.Generally, couplings made of metal elements that do not require lubrication are more reliable; couplings that require lubrication are easily affected by the perfect degree of lubrication and may pollute the environment.Couplings containing non-metallic components such as rubber are more sensitive to temperature, corrosive media and strong light, and are prone to aging
2 The size and nature of the torque to be transmitted and the requirements for the buffering and damping function.For example, for high-power and heavy-duty transmissions, gear couplings can be selected; for transmissions that require severe impact loads or to eliminate shaft torsional vibration, tire couplings and other couplings with high elasticity can be selected.
3 The magnitude and direction of the relative displacement of the two axes.When it is difficult to maintain strict and precise alignment of the two shafts after installation and adjustment, or when the two shafts will have a large additional relative displacement during the working process, a flexible coupling should be used.For example, when the radial displacement is large, you can choose a slider coupling, and when the angular displacement is large or the connection of two intersecting shafts, you can choose a universal coupling.
4 Manufacturing, installation, maintenance and cost of the coupling.On the premise of meeting the convenience performance, couplings with convenient assembly and disassembly, simple maintenance, and low cost should be selected.For example, the rigid coupling is not only simple in structure, but also easy to assemble and disassemble, and can be used for low-speed, high-rigidity drive shafts.
5 The working speed of the coupling and the centrifugal force caused by it.For high-speed transmission shafts, couplings with high balance accuracy, such as diaphragm couplings, should be selected, rather than slider couplings with eccentricity.
