Drum gear couplingThere are Type I and Type II, which are suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries, and also suitable for shaft transmission of various machinery such as petroleum, chemical industry and general machinery.
The difference between Type I and Type II of the drum gear coupling: Type I-the sealed end is a separate type, with a large tooth spacing, which allows large radial displacements, and can be connected with Y, J1, and Z1 shaft extensions . Type II-sealing end is integral, with small tooth spacing, relatively small radial displacement, compact structure, small moment of inertia, and can be connected with Y and J1 shaft extensions.
The drum gear coupling is a rigid-flexible coupling. The gear coupling is composed of an internal gear ring with the same number of teeth and a flange half coupling with external teeth.The external teeth are divided into two types of tooth profiles: straight teeth and drum teeth. The drum gear coupling can allow a larger angular displacement (compared to the straight tooth coupling), which can improve the contact conditions of the teeth and increase the transmission torque. Ability to extend service life.
When the 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 to be in good condition. And work in a sealed state.Gear couplings have small radial dimensions and large carrying capacity. They are used for low-speed and heavy-duty conditions and shafting transmissions. High-precision and dynamically balanced gear couplings can be used for high-speed transmissions, such as the shafting of gas turbines. transmission.Because the angular compensation of drum-shaped gear couplings is greater than that of straight-tooth couplings, they are widely used at home and abroad
