GAP Drum gear coupling with brake disc (Q/YG 12008X-2018)

Core Design and Structural Features:

1. Enhanced Misalignment Compensation Capability:
Compared with conventional models, the GAP coupling features a wider internal gear sleeve design. This specialized geometric structure provides superior axial displacement compensation capability, enabling the coupling to perform exceptionally well when handling complex alignment deviations.

2. Optimized Load Distribution Structure:
In typical industrial configurations, the GAP coupling is commonly paired with GBZ and GAZ couplings, with the intermediate shaft connected through the external gear sleeve end. The brake disc is directly mounted to the half coupling, allowing the weight load and vibration generated during braking to be fully absorbed by the half coupling. This design significantly improves the meshing performance of the crowned gear teeth during braking and greatly extends the service life of the entire transmission system.

3. Bidirectional Rotation Flexibility:
The product supports both clockwise and counterclockwise rotation, making it highly suitable for demanding operating conditions involving frequent starts, stops, and directional changes.

Key Performance Advantages:

1. Outstanding Power Transmission Capacity:
The product covers an extensive torque range, with nominal torque (Tn) capacities ranging from 630 N·m up to 112,000 N·m.

2. Strict Safety Standards:
To prevent mechanical damage, the design specification stipulates that the maximum braking torque (Tm) must not exceed twice the nominal torque (Tm ≤ 2Tn). This requirement provides a reliable safety margin for the entire transmission system.

3. High-Speed Performance:
Smaller models, such as the GAP1, offer allowable rotational speeds of up to 4,000 r/min while maintaining excellent rotational balance and low vibration levels even under high-speed operating conditions.

4. Maintenance-Friendly Design:
A dedicated dimension marked as “e” is defined within the structural parameters to provide the necessary clearance for seal replacement. This user-oriented design allows maintenance personnel to perform servicing and seal replacement conveniently without completely dismantling the system.

Technical Specifications Overview:
The GAP series is available in multiple models ranging from GAP1 to GAP14.

1. Bore Compatibility:
Supports a variety of shaft bore configurations, including Y-Y, J1-J1, and Z-Z combinations, providing flexibility for different installation requirements.

2. Brake Disc Specifications:
Standard brake disc diameters (D₀) range from 315 mm to 1000 mm, making the coupling compatible with a wide variety of mainstream disc brake systems.

3. Heavy-Duty Capability:
The maximum bore diameter (dz) reaches 220 mm, enabling the coupling to accommodate the power shaft systems of various heavy industrial machines.

Wide Range of Industrial Applications:
With its reliable braking integration and excellent compensation performance, the GAP coupling has become a preferred solution in numerous heavy industrial sectors.

1. Lifting and Port Machinery:
Serves as a critical component in hoisting and traveling mechanisms, ensuring precise starting, stopping, and positioning of heavy loads.

2. Metallurgical and Mining Equipment:
Maintains the stability of power transmission systems under severe operating conditions characterized by high temperatures and heavy impact loads.

3. Water Treatment, Paper Manufacturing, and Conveyor Systems:
Provides durable and reliable power transmission support in production lines requiring long shaft connections and frequent braking operations.
