1. Strong carrying capacity.Under the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the carrying capacity of the drum gear coupling is on average 15-20 higher than that of the straight drum gear coupling;

　　2. Large amount of angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the straight drum gear coupling is 1º; while the allowable angular displacement of the drum gear coupling is 1º; 30”, an increase of 50, at the same Under the modulus, number of teeth, and tooth width, the allowable angular displacement of the drum gear is larger than that of the straight tooth;

　　3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of squeezing the edge of the straight tooth and stress concentration under the condition of angular displacement, and at the same time improves the friction and wear of the tooth surface, and reduces Noise, long maintenance period;

　　4. The tooth end of the outer gear sleeve is in the shape of a horn, which makes the assembly and disassembly of the inner and outer teeth very convenient.

　　5. The transmission efficiency is as high as 99.7.Based on the characteristics of warp, drum gears have generally been used inside and outside to replace straight drum gear couplings. The drum-shaped gear coupling produced by UMA has a complete range of specifications and conforms to the corresponding standards.Drum-shaped gear couplings are rigid, flexible, and inelastic, so they are not suitable for machinery that requires damping, buffering, and two-axis alignment.

　　Drum-shaped drum-shaped gear couplings are adaptive and self-tuning technologies that can compensate for load changes, especially distributed drum-shaped gear couplings with communication, networking functions and integrated PLC; on the other hand, simple or industrial Special drum-shaped gear coupling and mechatronics, miniaturized drum-shaped gear coupling.Drum-shaped gear coupling is a key equipment for energy saving.According to online media statistics, the current motor with variable load and energy saving potential is at least 1.8 million kilowatts, which provides a huge market for the application of drum gear couplings.The application of drum-shaped gear couplings has expanded from common fans and 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 full Digitization and complete functions. In addition, due to the advent of new high-voltage power electronic devices, high-voltage and medium-pressure drum gear couplings have also made considerable progress.
