Drum gear coupling has the following characteristics: 1), good compensation performance.Because the outer gear bushing is a drum-shaped tooth, the coupling can avoid angular contact between the inner and outer gears when working, allowing the two-axis axis angular displacement of 1.5, and it can work reliably when the angular displacement is 2 to 3.Generally recommended
Drum gear coupling has the following characteristics:
1）、补偿性能好。由于外齿轴套为鼓形齿，联轴器工作时可避免内外齿棱角接触，允许两轴轴线角位移±1.5º，当角位移在2～3º时也能可靠的工作。一般推荐允许角位移1º30ˊ～2º30ˊ；
2). It can withstand heavy loads and impact loads, and its load-bearing capacity is 15-20% higher than that of straight gear couplings under the same angular displacement;
3) High efficiency, up to 0.99;
4) Good airtightness, reliable use, convenient loading and unloading and maintenance;
Compared with straight-tooth couplings, drum-shaped gear couplings have smaller dimensions, larger load-bearing capacity, and work reliably at high speeds.It is suitable for smelting, steel rolling, heavy machinery, steam turbine, petrochemical industry, shipbuilding and other industries.
