The characteristics of drum gear couplings (compared to straight gear couplings with the following characteristics) 1. Strong bearing capacity.Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load-bearing capacity of the drum gear coupling can be evenly improved by 15-20% compared with the straight gear coupling; 2. 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; while the allowable angular displacement of the drum gear coupling is 1º; 30”, 50% improvement, in the same mold In terms of number, number of teeth, and tooth width, the allowable angular displacement of the drum-shaped tooth is larger than that of the straight tooth; 3. The drum-shaped tooth surface improves the contact conditions of the inner and outer teeth and prevents the edge of the straight tooth under the condition of angular displacement. The disadvantages of squeezing and stress concentration, while improving the friction and wear of the tooth surface, reducing noise, and long maintenance cycle; 4. The tooth end of the outer gear sleeve has a horn shape, 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-shaped gears have been widely used at home and abroad to replace straight-tooth couplings. The drum gear coupling produced by UMA has a complete range of specifications and conforms to the corresponding specifications.Drum-shaped gear couplings are rigid, flexible, and inelastic, so they are not suitable for machinery that requires damping, buffering, and two-shaft alignment.


The main advantages of the WG drum gear coupling are: after the drum tooth meshing tooth surface is carburized and quenched, the load capacity is high; the main failure mode of the drum tooth is wear, and the tooth surface is smoothed by forced thin oil. The wear is greatly reduced, and the amount of wear is about 10% of the smooth grease. The circulating thin oil can take away the rolling heat at the end of the roll and the heat generated by the friction of the gear teeth, effectively avoiding the reduction of the allowable contact stress on the surface of the gear teeth; under normal conditions , Will not show the phenomenon of broken teeth, and meet the requirements of continuous rolling mill working characteristics; the drum gear coupling can meet the requirements of rolling mill rolling, and the expansion is very convenient; the use of safe, clean, efficient and other characteristics.


Drum-type gear coupling can compensate for load changes with self-adaptive and self-tuning technology, especially the distributed high-end drum gear coupling with communication, networking functions and integrated PLC; on the other hand, it is 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 1.8 million kilowatts, which provides an extremely large market for the application of drum gear couplings.The application of drum gear couplings has expanded from common fans and water pumps to food, beverages, logistics, buildings, etc., and new energy-saving areas have been expanded from time to time. Its functions have also been improved and diversified. The functions are complete. 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.
