WGCⅡ drum gear coupling
WGCⅡ drum-shaped gear coupling is a rigid-flexible coupling, with radial, axial and angular axis deviation compensation capabilities. Compared with the CL type straight gear coupling, it has a compact structure and a small turning radius. , The advantages of large carrying capacity, low transmission, low noise and long maintenance period.It is especially suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shafting transmission of various machinery such as petroleum, chemical, general machinery and so on.
The characteristics of WGCⅡ drum gear coupling are introduced:
1. Carrying.In the same inner gear sleeve outer diameter and couplingWith a large outer diameter, the load-carrying capacity of the drum gear coupling is 15-20% higher than that of the straight gear coupling on average;
2. Large amount of angular displacement compensation.When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1dm, and the allowable angular displacement of the drum gear coupling is 1dm, which is increased by 50%. Under the width, the 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 maintains it. Long cycle
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 the warp, drum-shaped teeth have generally been used instead of straight-tooth couplings.
With the rapid development of modern industrial technology, technical and economic indicators such as the carrying capacity, performance, efficiency, circumferential speed, volume and weight of the WGCⅡ drum gear coupling have been put forward increasingly high requirements. WGC Ⅱ drum gear coupling is developed on the basis of straight gear coupling to meet the technical requirements of large inclination angle, variable inclination angle, small size and high performance.The structure of the drum gear coupling is basically symmetrical.
