Drum gear coupling

Drum gear couplings are rigid-flexible couplings, with radial, axial and angular axis deviation compensation capabilities. Compared with CL type spur gear couplings, they have compact structure, small gyration radius, and load-bearing capacity. It has the advantages of large capacity, high transmission efficiency, low noise and long maintenance period.

The drum gear coupling is suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical industry and general machinery.

The characteristics of drum gear couplings (compared to straight gear couplings with the following characteristics)

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

2. The angular displacement compensation of the drum gear coupling 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”, an increase of 50%, in the same mold Under the condition of number, tooth number and tooth width, the allowable angular displacement of drum gear is larger than that of straight tooth;

3. The drum-shaped tooth surface of the drum-shaped gear coupling improves the contact conditions of the inner and outer teeth, avoiding the disadvantages of spur tooth end edge extrusion and stress concentration under angular displacement conditions, and at the same time the tooth surface friction , Wear conditions, reduce noise, and long maintenance cycle;

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. High transmission efficiency.Based on the characteristics of the warp, drum-shaped teeth have generally been used instead of straight-tooth couplings.Drum-shaped gear couplings have complete varieties and specifications, and comply with 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.

Digital function

Drum gear coupling can compensate for load changes adaptive and self-tuning technology, especially distributed drum gear coupling with communication, networking 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, there are currently at least 1.8 million kilowatts of motors with variable loads and potential for energy saving, which provides a huge market for the application of drum gear couplings.The application of drum gear couplings has expanded from common fans and pumps to food, beverages, logistics, buildings, etc., continuously expanding the energy-saving fields, and its functions are also improved and diversified. On the one hand, it is fully digital and functional. 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.
