The drum gear coupling is a rigid-flexible coupling, which is composed of an internal ring gear with the same number of teeth and a flange half coupling with external teeth. The external teeth are divided into two types of straight teeth and drum teeth. The drum gear coupling can allow a larger angular displacement (relative to the straight tooth coupling), which can improve the contact conditions of the teeth and increase the torque transmission. Ability to extend service life.

Drum gear couplings have the ability to compensate for axial deviations in radial, axial, and angular directions. Compared with straight gear couplings, they have a compact structure, a small radius of gyration, a large carrying capacity, high transmission efficiency, and low noise. The advantages such as long maintenance cycle are especially suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and pulping industry, as well as the shafting transmission of various machinery such as petroleum, chemical, and general machinery.

The drum gear coupling, model DC, is consisted of seals, the outer end cover, the load-carrying ring, the hub with. crowned spur gear teeth, the flanged housing with internal gear teeth, and the inner end cover.

Selection of drum gear coupling

When selecting a coupling, the coupling should be selected based on the needs of the drive system of the shaft system, and it should be avoided to simply consider the coupling between the master and driven ends. 8 points to consider
