GBLZ Drum gear coupling with brake wheel (Q/YG 11005X-2018)

Product Overview:
The GBLZ Series Drum-Gear Coupling with Brake Wheel represents the forefront of mechanical engineering innovation, combining traditional drum-gear coupling designs with advanced braking technology. Engineered to deliver both efficient torque transmission and precise braking capabilities in industrial applications, this product is the ideal choice for environments where safety, efficiency, and reliability requirements are exceptionally high.

Key Features and Advantages:

1. Exceptional Torque Transmission and Misalignment Compensation: The coupling features a robust drum-gear design with internal gear teeth that ensure seamless torque transmission between shafts. This structure not only supports high torque loads but also compensates for angular, radial, and axial misalignments, thereby reducing mechanical stress and extending equipment service life.

2. Integrated Precision Braking Function: A unique feature of this product is the direct integration of a brake wheel into the coupling mechanism. This innovative design enables controlled deceleration or stopping—whether for gradual slowdowns during routine operations or immediate halts in emergency situations—providing precise speed control and significantly enhancing safety.

3. High-Quality Materials and Durability: Manufactured using high-grade steel or alloy steel, the product demonstrates exceptional durability, corrosion resistance, and reliability, even under heavy-load conditions.

4. Convenient Installation and Maintenance: Thanks to its modular and user-friendly design, the coupling integrates seamlessly into existing systems. Its maintenance process is straightforward, requiring minimal downtime for inspection, repair, or replacement, thereby optimizing overall productivity.

Key Technical Parameters:
According to technical documentation and data sheets, this series comprises various models ranging from GBLZ1 to GBLZ14. Key parameters include:

Nominal Torque (Tn): Ranging from 0.63 kN·m (GBLZ1) to 125 kN·m (GBLZ14).
Allowable Speed ([n]): Up to 4000 r/min (GBLZ1), with larger models—such as the GBLZ14—rated at 950 r/min.
Bore Diameter (d1, d2, dZ): Supports a wide range of sizes, with a maximum tapered bore diameter of up to 220 mm.
Brake Wheel Diameter (D₀): Standard sizes include 160mm, 200mm, 250mm, 315mm, 400mm, 500mm, 630mm, 710mm, and 800mm.
Brake Wheel Mass and Moment of Inertia: For example, a 160mm brake wheel has a mass of 2.83 kg, while an 800mm brake wheel reaches a mass of 203 kg.

Structural Types:
This product is available in two primary structural types (Type I and Type II) to accommodate various installation requirements. In the design, dimension B₂ is specifically designated as the clearance space required for seal replacement.

Application Industries:
The GBLZ-type coupling, manufactured by MCC Heavy Industry Technology (Zhenjiang) Co., Ltd., is widely utilized in the following industries:
- Metallurgical Equipment and Mining Machinery
