Aodisi GIICL Type Drum Gear Metal Couplings (applies to JB/T8854.2-2001)

·Model: GIICL Type

·Norminal Torque: 0.4kN. M – 4500kN. M

·Allowed Rotation Speed: 4000rpm -460rpm

·Connection:Keyway & Shaft hole

·Shaft Hole Diameter: 16mm – 1040mm

·Shaft Hole Length (Y): 42mm – 1100mm

·Applications: Metallurgy, mining, lifting and transportation industries, petroleum, chemical, general machinery and other heavy machinery shaft drive.

GIICL-type drum gear coupling sealed end is integrated type, the tooth space width is small, the allowable radial displacement is small, compact structure, small inertia, and can connect Y, J1-type shaft hole.

Drum-type Gear Coupling Features (compared with the straight-type coupling):

• High carrying capacity

The bearing capacity of the drum-type gear coupling is 15 to 20% higher than that of the straight-type coupling in the same outer diameter and the maximum outer diameter of the coupling.

• Large angular displacement compensation

When the radial displacement is equal to zero, the allowable angular displacement of the straight-tooth coupling is 1°, but the allowable angular displacement of the drum gear-type coupling is 1°30", 50% increased. With the same modulus, tooth number, tooth width, the allowable angular displacement of the drum teeth is larger than of the straight teeth.

• Drum-type gear surface has improved the internal and external contact conditions, which avoids the drawbacks of angular displacement of the mandibular tooth edge extrusion and stress concentration, in the meanwhile improves the tooth surface friction, wear conditions, reducing noise, long maintenance cycle.
• The tooth end of outer teeth set is horn shape, so that the internal and external tooth assembly and disassembly is very convenient.
• Transmission efficiency is up to 99.7%.

• Main dimensions for your kind choice.
