Henan rigid coupling

Rigid coupling is a torsionally rigid coupling. Even when it is under load, there is no backlash. Even when the load is caused by deviation, the rigid coupling still transmits torque rigidly.

Rigid couplingIt is composed of rigid force-transmitting parts, and the connecting parts cannot move relative to each other. Therefore, it does not have the ability to compensate for the relative offset of the two axes. It is only suitable for the strict alignment of the connected two shafts during installation, and no two shafts are generated during work. In the case of relative deviation, the flange coupling has no elastic elements, and does not have the function of damping and buffering. Generally, it is only suitable for working conditions where the load is stable and there is no shock and vibration.

Rigid couplings were also called fixed rigid couplings in the past, including flange couplings, radial key flange couplings, open shaft couplings, clamp couplings, sleeve couplings Wait.Rigid couplings are generally simple in structure and low in manufacturing cost.When selecting a rigid coupling, the axis alignment error of the connected two shafts should be minimized. In order to reduce the impact of additional load on the coupling, the distance between the coupling and the bearing should be minimized. .

The structure of the rigid coupling: The rigid coupling consists of two half couplings with grooves on the end faces and an intermediate disc with convex teeth on both sides. Because the convex teeth can slide in the grooves, Therefore, the relative displacement between the two shafts during installation and operation can be compensated. The rigid coupling also has two shaft sleeves and a central steel shell, of which the central steel shell is a torque transmission element.

Before disassembling the rigid coupling, make some marks on the coordinated positions of the various parts of the coupling for reference during reassembly.For Lingsi couplings used in high-speed machines, the connecting bolts have been weighed and marked clearly and cannot be mistaken.When disassembling the coupling, generally disassemble the connecting bolt first.Because a layer of grease, corrosion products and other deposits are deposited on the surface of the thread, the bolt is not easy to disassemble, especially for the heavily corroded bolt, it is very difficult to disassemble.

For the removal of connecting bolts, choose appropriate tools, because the bearing surface of the bolt's outer hexagon or inner hexagon has been slipped and damaged, and the disassembly will be more difficult.For bolts that have been rusted or have a lot of grease, solvents (such as rust loosening agent) are often used to spray the joints of the bolts and nuts to allow the solvent to penetrate into the threads, which will make it easy to disassemble the rigid coupling.
