Flange coupling features: simple structure, low cost, can transmit large torque, does not allow relative displacement of the two shafts, without buffering.
Uses: Widely used in occasions with low speed, no impact, high shaft rigidity and good neutrality.
Slider coupling: The groove on the half coupling and the tenon of the middle slider-moving pair-can compensate for the offset of the two axes. Features and applications: no buffer, the moving pair should be lubricated for low-speed transmission.
Features of the elastic coupling: Buffer and absorb vibration, which can compensate for large axial displacements, small radial displacements and angular displacements.
Application: There are many positive and negative changes, and the high-speed axis that starts frequently.
Rigid coupling does not have the ability to compensate for the relative deviation of the axis of the two coupled shafts, nor does it have cushioning and shock absorption performance; but the structure is simple and the price is cheap.Rigid couplings can only be used when the load is stable and the speed is stable, and the relative deviation of the axes of the two shafts to be coupled is extremely small.
The flexible coupling has a certain ability to compensate the relative offset of the two shafts being coupled, and the maximum amount varies with different models.
Flexible coupling without elastic elements: large load-bearing capacity, but also does not have cushioning and shock absorption performance, and there will be impact noise at high speed or unstable rotation or frequent forward and reverse rotation.It is suitable for occasions with low speed, heavy load and stable speed.
The flexible coupling of non-metallic elastic elements has good cushioning and shock absorption performance when the speed is not stable; but due to the low strength of non-metallic (rubber, nylon, etc.) elastic elements, short life, small load-bearing capacity, and high temperature resistance Low temperature, so it is suitable for high speed, light load and normal temperature occasions.
Flexible coupling of metal elastic elements: In addition to having better cushioning and shock absorption performance, it has a large load-bearing capacity, and is suitable for large changes in speed and load and high or low temperature occasions.
