GJC drum coupling(Q/YJ 16028X-2018)

The GJC type drum coupling is a high-performance transmission component specially designed for the drums of lifting machinery (such as cranes and hoists). Its main features are as follows:

1. Suitable angle compensation capability
With a drum-shaped tooth design, it allows for a significant angular displacement between the two axes (typically ±0.5°). This is highly adaptable to installation errors of the drum axis and the reducer axis in lifting machinery, as well as dynamic skew during operation.

2. High load-bearing capacity and rigidity
It has a high torque transmission capacity, a compact structure, and can withstand large impact loads and vibrations, meeting the heavy-load requirements of lifting operations.

3. Excellent lubrication and sealing
It is usually equipped with reliable sealing devices, which can effectively prevent lubricant leakage and the entry of dust and water, extending the service life of the tooth surface.

4. Convenient installation and maintenance
The design usually allows for a certain degree of adjustment under load and some models support axial installation or disassembly, facilitating maintenance in a confined space.

5. Special drum connection method
Specifically designed for the drum, it usually adopts direct connection between the inner tooth ring and the drum housing (welding or bolt connection), and the outer tooth sleeve is connected to the output shaft of the reducer to achieve the drive of the drum.

Summary: The GJC type coupling combines the flexibility of drum-shaped gears with the rigidity for heavy loads, and is a crucial component in the drive system of hoisting machinery drum.
