HangzhouGICL type-drum gear coupling

GICL type-drum gear coupling (JB/T 8845.3-2001) is a rigid-flexible coupling. The gear coupling consists of an inner gear ring with the same number of teeth and a flange half coupling with external teeth. And other parts.The external teeth are divided into two types: 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-shaped gear couplings are allowed. Larger angular displacement (compared to spur gear couplings), the contact conditions of the teeth can be improved, the torque transmission capacity is improved, and the service life is prolonged.The contact state along the tooth width when there is an 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 gyration radius, large carrying capacity, low transmission, low noise and long maintenance period. It is especially suitable for low-speed and heavy-duty conditions, such as metallurgy, It is also suitable for shafting transmission of various machinery such as petroleum, chemical industry, general machinery, etc. in mining, lifting and transportation industries.

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

1. Carrying.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 on average 15-20% higher than that of the straight gear coupling; 

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

3. The drum-shaped tooth surface makes the contact conditions of the inner and outer teeth avoid the disadvantages of squeezing the edge of the straight tooth and stress concentration under the condition of angular displacement. At the same time, it reduces the friction and wear of the tooth surface, reduces the noise, and maintains it. Long 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 gears convenient. 

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 specifications of the drum-shaped gear coupling 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-axis alignment.
