The drum gear coupling belongs to the rigid flexible coupling

The drum tooth coupling has a small radial size and large load-bearing capacity, and is commonly used for shaft transmission under low speed and heavy load conditions. The drum tooth coupling, which is dynamically balanced, can be used for high-speed transmission, such as shaft transmission of gas turbines. The gear blank only rotates, and the center of the hob moves in a circular arc to complete the vertical and horizontal feed of the gear blank. This method is used when the hobbing machine is equipped with a hob feed mechanism for processing drum shaped teeth; The drum type gear coupling is not suitable for machinery that requires vibration reduction, buffering, and strict alignment requirements. The surface needs to be carburized or tempered, otherwise the hardness of the tooth surface will be different.

When refueling, it is not advisable to add too much, as long as it reaches the standard value. Adding too much will only cause a burden on the machine and cause it to malfunction. The drum gear coupling has the ability to compensate for radial, axial, and angular axis deviations, and is particularly suitable for low-speed and heavy-duty working conditions such as metallurgy, mining, lifting and transportation industries. It is also suitable for shaft transmission of various machinery such as petroleum, chemical, and general machinery. The drum gear coupling is a rigid flexible coupling composed of internal gear rings with the same number of teeth and flange half couplings with external teeth, making it more convenient to use.

The drum tooth coupling

After a machine has been in use for a long time, its various parts will also age, and some may even be damaged during operation. If these hazards cannot be detected in a timely manner, it will not only cause low work efficiency during operation and use, but also may cause damage to workers. We usually use drum gear couplings the same way. Before each use, check the condition of each component to see if there is any damage or malfunction. If any damage is found, repair it in a timely manner and loosen the lubricating oil of the machine. If there is not much oil, add more.

External teeth are divided into two types: straight teeth and drum shaped teeth. The so-called drum shaped teeth refer to the spherical shape of the external teeth, with the center of the spherical surface on the gear axis and larger tooth side clearance than ordinary gears. The drum shaped tooth coupling can allow for larger angular displacement, improve the ability to transmit torque, extend service life, and maintain contact status along the tooth width when there is angular displacement. During operation, the drum gear coupling generates relative angular displacement between the two shafts, and the tooth surfaces of the inner and outer teeth periodically slide axially, resulting in tooth wear and power consumption. Therefore, the drum gear coupling needs to operate in a well sealed state.
