GICL type-drum gear coupling (JB/T 8845. 3-2001) is a rigid-flexible coupling. The gear coupling is a semi-connected inner ring gear with the same number of teeth and a flange with outer teeth. It is composed of shafts and other parts.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Drum gear couplings are allowed. Larger angular displacement (compared to straight tooth coupling) improves the torque transmission capacity and prolongs the service life.The contact state along the tooth width when there is angular displacement.It has the ability to compensate for axis deviation in radial, axial and angular directions, and has the advantages of compact structure, small turning radius, large carrying capacity, low transmission, low noise and long maintenance period. It is especially suitable for low-speed and heavy-duty working conditions, such as metallurgy, It is also suitable for shaft transmission of various machinery such as petroleum, chemical industry, general machinery, etc. in mining, lifting and transportation industries.
The characteristics of drum gear couplings (compared to straight gear couplings with the following characteristics) 1. Load bearing.Under the same outer diameter of the inner gear sleeve and the large outer diameter of the coupling, the load-bearing capacity of the drum gear coupling is 15-20% higher than that of the straight gear coupling on average; 2. Large angular displacement compensation.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, 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 makes the inner side and avoids the disadvantages of the edge of the straight tooth end being squeezed under the condition of angular displacement and stress concentration. At the same time, the friction and wear conditions of the tooth surface reduce the noise and the maintenance cycle is long; 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 easy. 5. The transmission reaches 99.7%.Based on the characteristics of the warp, at present, drum-shaped teeth have generally been substituted for straight-tooth couplings. The varieties of drum-shaped gear couplings produced by UMA meet 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-shaft alignment.
