GIICL type drum gear coupling is up to standard

In short, the correct installation of GIICL type drum gear coupling can improve the running condition of the equipment, reduce the vibration of the equipment and extend the service life of the coupling. Inspection after assembly of GIICL type drum gear coupling After assembling the hub of the coupling on the shaft, the hub should be carefully checked for perpendicality and coaxiality to the shaft. Is generally set in the hub end face and the outer circle of two dial indicator, turning the shaft rotation, observe the hub of the full runout (including end runout and radial runout) value, determine the hub and shaft perpendicularity and coaxiality of the situation. I plant the production of plum coupling. Different speed of the coupling on the full runout requirements of different values, different types of coupling on the full runout requirements of different values, however, after the hub in the shaft assembly, make the hub full runout deviation value in the design requirements of the tolerance range, this is GIICL type drum gear coupling assembly of one of the main quality requirements. There are many reasons why the hub runout value does not meet the requirements. First of all, it may occur in the manufacturing due to the error caused by processing and for on-site assembly, mainly due to the improper treatment of the surface of the hub hole, so that the concentricity of the hub and the shaft deviation. Another reason is that there is a key coupling in the assembly, due to the improper assembly of the key causes the hub and the shaft is not coaxial. The correct installation of the key should make the two sides of the key closely fit with the wall of the keyway. It is generally checked by coloring method during assembly. If the fit is not good, it can be repaired by file or shovel knife to make it meet the requirements. For the coupling that needs to be used for a long time, it should be coated with antirust oil maintenance. There are many structural types of coupling, and the specific assembly requirements and methods are different. For installation, the general principle is to assemble in strict accordance with the requirements of the drawings, and the specific can only introduce some problems that often need to be paid attention to in the assembly of coupling.

GIICL type drum gear coupling assembly after how to debug? When tightening the connecting bolt, the coupling transmission should be symmetrical and tightened gradually, so that the locking force on each connecting bolt is basically the same, so that the coupling will not produce skew phenomenon after assembly because of the uneven force of each bolt, and the torque wrench can be used if possible. After the assembly should check whether the rigid movable parts of the coupling can be moved a small amount, there is no card astringent phenomenon. All kinds of couplings in the assembly, should be turned to see whether the rotation is good.

The upper part of the key of GIICL type drum gear coupling generally needs to leave a gap, the gap is about 0.1-0.2mm. Because some high-speed rotating machinery for hub and shaft coaxiality requirements are high, with single key connection can not get high coaxiality, with double key connection or spline connection can make the two coaxiality. The parts of the coupling should be cleaned before installation. After cleaning, the parts should be dried with washing oil. The coupling ready to run in a short time can be coated with turbine oil or oil on the surface of the parts after drying to prevent rust.
