  • WGT Type Intermediate Sleeve

The WGT type intermediate sleeve drum gear coupling is a high-performance mechanical transmission component, mainly composed of half couplings with internal and external gear structures and a drum gear intermediate sleeve. It achieves efficient torque transmission through the special geometric design of the drum gear and features axial, angular, and radial displacement compensation functions. It is widely used in heavy machinery, lifting equipment, metallurgy, chemical industry, and other fields. This product integrates the core technology of "Meichen Couplings," combining strong load capacity, wide compensation range, and reliable operation.

Classification

1. By structural form: Drum gear coupling (split structure with intermediate sleeve)
2. By application field: Heavy-duty machinery couplings, lifting equipment couplings, metallurgical transmission couplings
3. By compensation function: Angular compensation type, axial compensation type, comprehensive displacement compensation type
4. By model series: WGT series (specifically refers to drum gear couplings with intermediate sleeves)

Product Advantages

The core structure of the WGT type intermediate sleeve drum gear coupling includes:

- Drum gear intermediate sleeve: Uses high-precision drum gear design, with gear surfaces specially heat-treated, providing excellent load capacity and wear resistance. It is the key component for compensating relative displacement between two shafts.

- Half couplings: Used in conjunction with the intermediate sleeve, connected by high-strength bolts to form a separable split structure, facilitating installation and maintenance.

- Sealing and lubrication system: Built-in high-efficiency sealing rings prevent grease leakage while ensuring sufficient lubrication of gear surfaces, reducing friction loss.

- High load capacity: The drum gear design effectively disperses stress, with a maximum transmitted torque reaching tens of thousands of Newton-meters.

- Large angle compensation: Allows a maximum angular displacement between two shafts of 3°-5°, adapting to shaft alignment deviations under complex working conditions.

- Long service life: Made of high-quality alloy steel and precision manufacturing processes, combined with reliable lubrication, ensuring continuous operation life exceeding 8000 hours.

- Easy maintenance: The split design of the intermediate sleeve allows component replacement without moving the main machine, reducing maintenance costs.

Scope of Application

1. Lifting equipment: Drum drive systems (such as the "Beijing Drum Coupling Model" mentioned in the picture), crane slewing mechanisms, hoist lifting mechanisms.

2. Heavy machinery: Mining machinery (crushers, conveyors), port machinery (ship loaders, gantry cranes), construction machinery (excavators, bulldozers) transmission shafts.

3. Metallurgical industry: Shaft connections for rolling mills, fans, and pump equipment.

4. Power transmission: Torque transmission between diesel engines, motors, and reducers, especially suitable for frequent start-stop and impact load conditions.

Working Principle

Torque transmission: The torque from the motor or power source is transmitted through the internal gear ring of the driving half coupling to the external gear shaft of the drum gear intermediate sleeve, then meshed by the internal gear of the intermediate sleeve with the external gear of the driven half coupling, finally transmitting torque to the driven equipment.

Displacement Compensation:

- Angular compensation: When angular displacement occurs between two shafts, the special curved surface of the drum gear allows sliding motion between gear surfaces, reducing friction through grease lubrication, achieving automatic angular displacement adjustment.

- Axial compensation: The axial clearance design between the half coupling and the intermediate sleeve absorbs axial displacement.

- Radial compensation: Combined with angular and axial compensation, indirectly adapts to radial deviation.

Lubrication and sealing: Grease fills the gear cavity, and sealing rings prevent impurities from entering, ensuring long-term operation of gear surfaces under low friction conditions.
