The Flexible Coupling can offset part of the circumferential stress with the stress produced, so as to reduce the stress error. Before fitting, the inner diameter of the outer cylinder of the double-layer combined jacket is slightly smaller than the outer diameter of the inner cylinder. Generally, the outer cylinder is heated to expand by the method of heat jacket, and the heat jacket is put on the inner cylinder. When the outer cylinder is cooled and contracted, the inner cylinder is tightly clamped; The multi-slit type allows for shortening the slit without weakening the tolerance capacity. The short slit makes the torque stiffness of the coupling increase and overlap, so that it can withstand considerable torque. The Flexible Coupling is suitable for light load applications.
The unreasonable structure of the Flexible Coupling will also bring additional load to the bearing, leading to premature failure of the bearing. In the start and stop system, it is recommended that users use the general Flexible Coupling with small inertia moment, which can reduce the energy consumption and the abrasion of parts during the start and delay. The vibration shall be reduced as much as possible when selecting Flexible Coupling, and the weight of machine tool will not be increased during the hot start time. High-quality images can only be taken when the machine is fully motioned in place and still. Shorter start-up time of the thermal engine can improve the productivity of the machine tool equipment. Industrial image system requires the Flexible Coupling to have a high torsional rigidity.
Flexible Couplings usually have two or three slits to deal with low torque rigidity. The multi-slit type allows for shortening the slit without weakening the ability to bear the deviation. The short slit makes the torque stiffness of the coupling increase and overlap, so that it can bear considerable torque. Flexible Coupling is suitable for the connection of servo motor and lead screw in light load applications. At the same time, this kind of performance is not without any negative effect. With the increase of the size of the slit exceeds that of the single-slit type, its bearing load will also increase, but in most cases, it can effectively protect the bearing.
