Drum gear couplings are adaptive and self-tuning technologies that can compensate for load changes, especially distributed high-end drum gear couplings with communication, networking functions and integrated PLC; on the other hand, they are simple or industry-specific Drum-shaped gear couplings and mechatronics, miniaturized drum-shaped gear couplings.

Drum-shaped gear coupling is a key equipment for energy saving. According to online media statistics, the current domestic motors with variable loads and energy-saving potential are at least 180 million kilowatts, which provides a huge market for the application of drum gear couplings. The application of drum gear couplings It has expanded from common fans and water pumps to food, beverages, logistics, buildings, etc., constantly expanding and new energy-saving fields, and its functions have also been improved and diversified. On the one hand, it is fully digital and fully functional. In addition, due to the new high-voltage power

With the advent of electronic devices, high-pressure and medium-pressure drum gear couplings have also made considerable progress. The characteristics of the drum gear coupling: strong load-carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load capacity of the drum gear coupling is on average higher than that of the straight gear coupling.

The angular displacement compensation is large. When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1º, and the allowable angular displacement of the drum gear coupling is 1º; 30'', an increase of 50%, under the same modulus, number of teeth, and tooth width, the allowable angular displacement of the drum tooth is larger than that of the straight tooth; 3. The drum tooth surface improves the contact conditions of the inner and outer teeth and avoids Under the condition of angular displacement, the disadvantages of the edge of the straight tooth are squeezed and the stress is concentrated. At the same time, the friction and wear of the tooth surface are improved, the noise is reduced, and the maintenance cycle is long.
