WGT type connecting middle sleeve drum gear coupling

WGT型接中间套鼓形齿式联轴器：

Drum gear coupling属于刚挠性联轴器，齿式联轴器是由齿数相同的内齿圈和带外齿的凸缘半联轴器等零件组成。外齿分为直齿和鼓形齿两种齿形，所谓鼓形齿即为将外齿制成球面，球面中心在齿轮轴线上， 齿侧间隙较一般齿轮大，鼓形齿联轴器可允许较大的角位移（相对于直齿联轴器），可齿的接触条件，提高传递转矩的能力，延长使用寿命。有角位移时沿齿宽 的接触状态。具有径向、轴向和角向等轴线偏差补偿能力，具有结构紧凑、回转半径小、承载能力大、传动、噪声低及维修周期长等优点，特别适用于低速重 载工况，如冶金、矿山、起重运输等行业、也适用于石油、化工、通用机械等各类机械的轴系传动。

When the intermediate sleeve drum gear coupling is working, the two shafts produce relative angular displacement, and the tooth surfaces of the inner and outer teeth periodically slide relative to each other in the axial direction, which will inevitably cause tooth surface wear and power consumption. Therefore, the gear coupling needs Work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shafting transmissions under low-speed and heavy-duty conditions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shafting. transmission.Because the angular compensation of drum gear couplings is greater than that of spur gear couplings, drum gear couplings are widely used. Straight gear couplings are obsolete products and should not be used as much as possible.

The characteristics of the drum gear coupling (compared with the straight gear coupling, it has the following characteristics):

1. Strong carrying capacity.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 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. The drum-shaped tooth surface enables the contact conditions of the inner and outer teeth to be obtained, avoiding the disadvantages of spur tooth end edge extrusion and stress concentration under the condition of angular displacement. At the same time, the friction and wear conditions of the tooth surface are reduced, and the noise is reduced. Long maintenance period.

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 teeth very 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.
