The importance of using lubricating oil for GIICL drum gear coupling was analyzed

The drum teeth of GIICL type drum gear coupling are actually made into a spherical surface by the outer teeth, and the center of the spherical surface is on the axis of the gear, and the side clearance of the teeth is larger than that of the general gear. The tooth coupling allows a large angular displacement relative to the straight coupling. And the contact conditions of the teeth are improved, so that the ability to transfer torque is improved, and the service life of the coupling is extended.

Clearance fit directly affects the service life of GIICL type drum gear coupling, the clearance between the circumference and the hole, according to the standard to have the corresponding size fit, that is, the degree of accuracy; The gap between the connector and the coupling, its cooperation will not only affect the product damage life, but also bring the transmission performance of the whole equipment, rigid coupling will also cause noise. Coupling gap and other problems, in the operation of mechanical equipment if the transmission parts to move back and forth will bring friction, damping pad plum coupling, star coupling especially prominent friction will double damage the connecting pad. If the reliable operation of the drum gear coupling is ensured, good lubrication can effectively reduce the wear.

Most GIICL type drum type coupling is used lubricating oil, because oil is filtered by the high precision filter, less than 10 microns, the degree of tooth surface requires continuous lubrication, or tooth surface temperature will rise and the accumulated water and dirt, some GIICL type drum type coupling with the structure of the oil slot, sometimes That is, the oil collecting groove is processed in the shaft hole of the outer gear, and the oil hole communicated with the oil collecting groove is drilled out at the bottom of the tooth groove of the outer gear. In order to make it fully lubricated, the oil is sprayed into the meshing place of the inner and outer teeth by virtue of the centrifugal force generated by the high-speed operation of the drum gear coupling.
