How to debug the drum gear coupling?
2022-12-08

How should we debug the drum gear coupling after assembly? For this kind of coupling product, in the process of tightening the connecting bolt, it should be tightened symmetrically and gradually, so that the locking force on each connecting bolt is basically the same, so as not to cause the coupling to produce skewing phenomenon after assembly because of the uneven stress of each bolt. If possible, the torque wrench can be used. All kinds of drum gear coupling in the assembly, should be turned to see whether the rotation is good.

The correct installation of the drum gear coupling can reduce the vibration of the equipment and prolong the service life of the coupling. Inspection after assembly of the coupling product After assembly of the hub of the coupling on the shaft, should carefully check the hub and shaft perpendicularity and coaxiality. Generally, two dial gauges are set on the end face of the hub and the outer circle. When the wheel turns the shaft, the full runout of the hub is observed (including the end face runout and radial runout), and the verticality and coaxiality of the hub and the shaft are determined. Our factory produces plum couplings. Different speed of the drum gear coupling to the full runout of the required value is different, different types of coupling to the full runout of the required value is also different, but after the hub in the shaft assembly, make the hub full runout of the deviation value in the design requirements of the tolerance range, which is one of the main quality requirements of the coupling assembly. There are many reasons why the full runout value of the hub does not meet the requirements. First, it may occur in the manufacturing due to the error caused by processing. For the on-site assembly, it is mainly due to the improper treatment of the surface of the inner hole of the hub, so that the concentricity of the hub and the shaft will be deviated. Another reason is that when the key coupling is assembled, the improper assembly of the key causes the hub and the shaft to be different.

At present, there are many structural types of drum gear coupling, but the specific assembly requirements and use methods of coupling products are different. For installation, the general principle is to strictly comply with the requirements of drawings for assembly, and the specific can only introduce some problems that often need to be paid attention to in coupling assembly.
