GⅡCLZ drum gear coupling is composed of internal gear ring with the same number of teeth and flange half coupling with external teeth.The external teeth are divided into straight teeth and drum teeth. The so-called drum teeth means that the external teeth are made into a spherical surface. The center of the spherical surface is on the gear axis. The tooth side clearance is larger than that of ordinary gears. Allows a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth, increase the torque transmission capacity, and prolong the service life.The contact state along the tooth width when there is angular displacement. 

When the GⅡCLZ 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 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.due toDrum gear couplingAngular compensation is greater than straight gear couplings, and drum gear couplings are widely used. Straight gear couplings are obsolete products, and those who choose them should try not to choose them.

Maintenance method of GⅡCLZ drum gear coupling:

1. Check the tooth surface meshing of the drum-shaped gear coupling. The contact area is not less than 50% along the tooth height and not less than 70% along the tooth width. The tooth surface must not be severely corroded, worn or cracked.

2. The full circle runout of the outer gear ring of the drum gear coupling is not more than 0.03mm, and the end circle runout is not more than 0.02mm.

3. If you need to remove the gear ring, use tools and don't knock, so as to avoid bending or damage to the shaft.When reinstalling, heat the ring gear to about 200°C before installing it on the shaft.The interference between the outer gear ring and the shaft is generally 0.01~0.03mm.

4. When reinstalling the intermediate tube or other parts, it should be assembled according to the original markings and data.

5. Tighten the bolts evenly with a torque wrench.

What are the requirements of the GⅡCLZ drum gear coupling for the drum curve? The drum tooth surface of the non-conjugated tooth surface is formed by gradually displacing the different end sections, and the displacement is formed by the dashed line with the axial coordinate. It is called the drum curve, which is an important geometric parameter of the drum gear coupling.The bulge curve is mostly a segment of arc, and there are also three arcs. These circles are called bulge circles. In the arc bulge curve, there are bulge circles on the axis of the gear, and others not on the axis; The bulge circle coincides with the spherical surface of the tooth surface, and some do not. Usually the design is based on experience. In general, the GⅡCLZ drum gear coupling should meet the following requirements:

No edge contact occurs when the inclination angle between the shafts is large;

The smaller the gear tooth concentrated load is, the better, and the curvature of the tooth surface is proportional to the circumference of the drum, so the drum radius is as large as possible.The curvature radius of the bulge curve is proportional to the single-sided thinning of the internal tooth, so the bulge circle radius should be as large as possible.The radius of curvature of the bulge curve is proportional to the single-sided thinning of the internal tooth, that is, it is related to the meshing gap of the tooth. Insufficient thinning may cause interference, and excessive thinning will weaken the strength of the tooth, and the backlash will be large. .
