Jiangsu WGT type intermediate sleeve drum gear coupling

The characteristics of WGT intermediate sleeve drum gear coupling (compared with straight gear couplings have the following characteristics):

1. Carrying.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 makes the contact conditions of the inner and outer teeth avoid the disadvantages of squeezing the edge of the straight tooth and stress concentration under the condition of angular displacement. At the same time, it reduces the friction and wear of the tooth surface, reduces the noise and maintenance The cycle is long.

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.

When the WGT type 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 The device needs to work in a good and sealed state.Gear couplings have small radial dimensions and large load-bearing capacity. They are often used in shaft transmissions under low-speed and heavy-duty conditions. The dynamically balanced gear couplings can be used for high-speed transmissions, such as gas turbine shaft transmissions.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.
