The drum-type coupling is a rigid flexible coupling with radial, axial and angular axis deviation compensation ability. Compared with the CL type straight-type coupling, it has the advantages of compact structure, small turning radius, large bearing capacity, high transmission efficiency, low noise and long maintenance cycle.
Basic introduction
- GICL, GIICL series drum gear coupling, especially suitable for low-speed and heavy-duty conditions, such as metallurgy, mining, lifting and transportation industries, but also suitable for petroleum, chemical, general machinery and other types of machinery shafting drive.
Equipment characteristics
Characteristics of drum type coupling (compared with straight type coupling has the following characteristics
- 1. Strong carrying capacity. Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the bearing capacity of the drum gear coupling is increased by 15 ~ 20% than that of the straight gear coupling on average.
- 2. Large amount of angular displacement compensation. When the radial displacement is equal to zero, the allowable angular displacement of the straight-gear coupling is 1º. The allowable angular displacement of the drum-type coupling is 1º 30 ", increased by 50%, under the same modulus, number of teeth, tooth width, drum teeth than the allowed angular displacement of straight teeth;
- 3. The drum tooth surface improves the contact conditions of the inner and outer teeth, avoids the disadvantages of the straight tooth end edge extrusion and stress concentration under the condition of angular displacement, improves the friction and wear of the tooth surface, reduces the noise, and has a long maintenance period; When increased by 50%, under the same modulus, tooth number and tooth width, the allowable angular displacement of drum teeth is larger than that of straight teeth.
- 4. the outer tooth sleeve tooth end is horn shape, so that the inner and outer teeth assembly and disassembly is very convenient.
- 5, transmission efficiency up to 99.7%. Based on the characteristics of warp, drum teeth have been widely used at home and abroad instead of straight gear coupling. UMA produces a complete range of drum gear couplings that meet the appropriate standards.
Drum gear coupling, its rigidity, flexibility, no elasticity, so it is not suitable for vibration reduction, buffering and two-axis alignment requirements of the strict machinery.
