Drum Gear Couplings

Drum Gear Coupling is an important mechanical basic component, belonging to rigid flexible coupling, and has a wide range of applications in the field of engineering technology. Drum Gear Coupling is composed of internal gear rings with the same number of teeth and flange half couplings with external teeth. Its core structure consists of an inner gear sleeve and an outer gear sleeve, and the outer gear adopts a drum shaped design with a spherical tooth tip. This design not only has a compact structure, but also has the characteristic of a small turning radius.

Advantages and Characteristics
Strong load-bearing capacity: Under the same outer diameter of the inner gear sleeve and the maximum outer diameter of the coupling, the load-bearing capacity of the Drum Gear Coupling is on average 15-20% higher than that of the spur gear coupling. This enables the drum toothed coupling to withstand greater loads and is suitable for various heavy-duty conditions.
Large angular displacement compensation: The Drum Gear Coupling has a large angular displacement compensation capability. When the radial displacement is equal to zero, the allowable angular displacement of the spur gear coupling is 1 °, while the allowable angular displacement of the drum gear coupling is 1 ° 30 ', an increase of 50%. This enables the Drum Gear Coupling to better adapt to axis deviations and ensure smooth transmission.
High transmission efficiency: The Drum Gear Coupling has a transmission efficiency of up to 99.7%, which can efficiently transmit power from the driving shaft to the driven shaft.
Low noise and long maintenance cycle: The drum shaped tooth surface improves the contact conditions between the inner and outer teeth, avoiding the drawbacks of edge compression and stress concentration at the straight tooth end under angular displacement conditions. At the same time, this design also improves the friction and wear of the tooth surface, reduces noise, and extends the maintenance cycle.
Easy to assemble and disassemble: The outer tooth sleeve of the Drum Gear Coupling has a trumpet shaped tooth end, making the assembly and disassembly of the inner and outer teeth very convenient and improving maintenance efficiency.

Drum Gear Couplings are particularly suitable for low-speed and heavy-duty working conditions, such as metallurgy, mining, lifting and transportation industries. At the same time, it is also suitable for shaft transmission of various types of machinery such as petroleum, chemical, and general machinery. Due to its many advantages, drum toothed couplings have been widely used in these fields.

Drum Gear Couplings come in various models and specifications, such as GICL, GIICL, WG, and more than ten other models. These models can meet the needs of different compensation requirements, brake function adaptation, and vertical installation scenarios. At the same time, different models of Drum Gear Couplings also have different load-bearing capacity, angular displacement compensation capacity, etc. Users can choose according to their actual needs.
