GAPK type with disc drum gear coupling (Q/YG 12009X-2018)

Product Overview: The GAPK type drum gear coupling with brake disc (standard: Q/YG 12009X-2018) is a transmission device specifically designed for use with disc brakes. This product supports bidirectional rotation, meeting the power transmission and braking requirements under complex working conditions.

Structural Features:

1. Double drum gear structure: Possesses excellent displacement compensation capability, effectively compensating for large axial misalignment.

2. Optimized brake disc arrangement: The brake disc is mounted on the driven end of the coupling, with the half-coupling fully bearing the weight, working braking load, and vibration of the brake disc. This design significantly improves the meshing performance of the drum gears during braking, enhancing the stability of the transmission system.

3. Insert-mount design: The brake disc adopts an insert-mount structure, allowing users to quickly replace the brake disc without disassembling the transmission equipment, greatly reducing maintenance time.

4. Compact structure and heat dissipation: The overall structural design is scientifically compact, providing excellent cooling and heat dissipation conditions for the brake disc, ensuring reliable performance under prolonged high-intensity operation.

Core Advantages:

1. High Safety: The maximum braking torque of the coupling is not limited by its own structural strength, ensuring safe and reliable performance.

2. Strong Load Capacity: Particularly suitable for heavy-duty applications with frequent changes in load, speed, and direction.

3. Versatile Configurations: Offers various shaft hole combinations (e.g., Y-Y, J1-J1, Z-Z, Z1-Z1, etc.) to adapt to different industrial interface requirements.

Technical Specifications:

1. Nominal Torque (T_n): 630 N.m to 112,000 N.m.

2. Permissible Speed (n): 1200 r/min to 4000 r/min (depending on the specific model).

3. Maximum Braking Torque (T_m): Should not exceed twice the nominal torque (i.e., T_m ≤ 2T_n).

4. Sizes: Covers various sizes from GAPK1 to GAPK14, adaptable to a wide range of shaft hole diameters.

Application Areas: This product series is widely used in heavy machinery industries with extremely high requirements for transmission precision and braking reliability, including: Metallurgical and Mining Equipment; Lifting and Port Machinery; Water Conservancy and Papermaking Equipment.
