The characteristics of drum-shaped gear coupling (compared with straight-tooth coupling, it has the following characteristics). 1. The bearing capacity is strong. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load-carrying capacity of the drum-shaped gear coupling is 15-20% more uniform than that of the straight-tooth coupling. 2. The angular displacement compensation is large. When the radial displacement is equal to zero, the allowable angular displacement of straight teeth coupling is 1 unite; while the allowable angular displacement of drum teeth coupling is 1 unite; 30', 50% progress. Under the same modulus, tooth number and tooth width, the allowable angular displacement of drum teeth is larger than that of straight teeth; 3. The contact condition of inner and outer teeth is improved by drum teeth surface to prevent it. Under the condition of angular displacement, the edge of straight teeth is extruded 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 period is long. 4. The tooth end of the outer gear sleeve is 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 meridian characteristics, drum teeth have been widely used to replace straight coupling at home and abroad. UMA consumption of drum-shaped gear coupling types and specifications are complete, and conform to the corresponding specifications. Drum-shaped teeth coupling is rigid, flexible and inelastic, so it is not suitable for machinery requesting shock absorption, cushioning and strict alignment of two axes.

The main advantages of WG type drum gear coupling are as follows: after carburizing and quenching treatment, the load-bearing capacity of the meshing surface of drum gear can be high; the main failure mode of drum gear is wear. After using forced light oil smoothing, the wear of the tooth surface can be greatly reduced, and the wear amount is about 10% of greasy smoothness. The rolling heat and rolling heat of roll end can be carried by circulating light oil. The heat generated by the friction of the gear teeth effectively avoids the reduction of the allowable contact stress on the surface of the gear teeth data; under normal conditions, the phenomenon of broken teeth will not occur to meet the requirements of the working characteristics of the continuous rolling mill; the drum-shaped gear coupling can meet the requirements of the rolling mill roll channeling, and the expansion is very convenient; safe, clean, efficient and so on. Characteristic.

Drum-shaped gear coupling can compensate for the self-adaptation and self-tuning technology of load variation, especially the high-end drum-shaped gear coupling with communication, networking function and integrated PLC. On the other hand, it is a simple or industry-specific drum-shaped gear coupling and a mechatronics, miniaturization drum-shaped gear coupling. Drum-shaped gear coupling is the key equipment to save energy. According to the statistics of network media, there are at least 180 million kilowatt motors with variable load and energy saving potential in China, which provides a huge market for the application of drum gear coupling. The application of drum-type teeth coupling has been extended from common fans and pumps to food, beverage, logistics, buildings and so on. From time to time, new energy-saving areas have been broadened, and its functions have been improved and diversified. On the one hand, it is fully digital and full-featured. In addition, due to the advent of new high-voltage power electronic devices, high and medium-voltage. Drum-shaped teeth coupling also has a considerable development.
