WGT type intermediate sleeve drum gear coupling

WGT型中间套鼓形齿式联轴器的特点(与直齿式联轴器相比有以下特点)：

1、承载。在相同的内齿套外径和联轴器外径下，鼓形齿式联轴器的承载能力平均比直齿式联轴器提高15～20％

2. Large angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1o, and the allowable angular displacement of the drum gear coupling is 1o30', an increase of 50%.Under the same modulus, number of teeth, and tooth width, the allowable angular displacement of the drum gear is larger than that of the straight tooth.

3、鼓形齿面使内、外齿的接触条件      ，避免了在角位移条件下直齿齿端棱边挤压，应力集中的弊端，同时   了齿面摩擦、磨损状况，降低了噪声，维修周期长。

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 warp, at present, drum-shaped teeth have generally been substituted for straight-tooth couplings.

WGT型中间套鼓形齿式联轴器在工作时，两轴产生相对角位移，内外齿的齿面周期性作轴向相对滑动，必然形成齿面磨损和功率消耗，因此，齿式联轴器需在有良好和密封的状态下工作。齿式联轴器径向尺寸小，承载能力大，常用于低速重载工况条件的轴系传动，并经动平衡的齿式联轴器可用于高速传动，如燃汽轮机的轴系传动。由 于鼓形齿式联轴器角向补偿大于直齿式联轴器，均广泛采用鼓形齿式联轴器，直齿式联轴器属于被淘汰的产品，选用者应尽量不选用。
