GICL drum gear coupling belongs to rigid-flexible coupling. Gear coupling is composed of inner gear ring with the same number of teeth and flange half coupling with external teeth. External teeth are divided into two types of tooth shapes: straight teeth and drum teeth. The so-called drum teeth are made into spherical surfaces with the center of the sphere on the gear axis. The tooth side clearance is larger than that of general gears. Drum gear coupling can allow larger angular displacement (relative to straight gear coupling), which can improve the contact conditions of teeth, improve the ability to transmit torque and extend service life. The contact state along the tooth width when there is angular displacement. It has the ability to compensate for radial, axial and angular axis deviations, and has the advantages of compact structure, small turning radius, large load capacity, high transmission efficiency, low noise and long maintenance cycle. It is particularly suitable for low-speed and heavy-load conditions, such as metallurgy, mining, lifting and transportation, etc. It is also suitable for shaft transmission of various types of machinery such as petroleum, chemical industry, and general machinery.
