Brake Disc Jaw Elastic Coupling

Overview of Elastic Coupling with Brake Disc

The Brake Disc Jaw Elastic Coupling is a reliable power transmission part for cranes, hoists, conveyors, and heavy-duty machinery. It combines torque transmission, vibration damping, and braking in one compact unit. This design improves safety and reduces space compared to traditional systems. Moreover, it ensures stable and efficient performance in demanding industrial conditions.

Structure and Design of Crane Jaw Coupling

This coupling includes two precision-machined hubs with curved jaws, a flexible elastic spider, and an integrated brake disc. The elastic spider, made from polyurethane or rubber, offers high durability, flexibility, and resistance to wear. In addition, its torsional elasticity reduces vibration, noise, and overload impacts while compensating for misalignment.

The integrated brake disc works directly with braking systems, delivering smooth and efficient stopping power. As a result, users eliminate the need for an extra brake wheel, which saves installation space and reduces maintenance costs.

Key Advantages of Brake Disc Elastic Shaft Coupling

• High torque capacity with compact structure

• Built-in braking disc for improved safety

• Elastic damping that absorbs shocks and vibration

• Compensation for axial, radial, and angular misalignment

• Durable elastic elements with oil resistance and long life

• Easy installation and low maintenance requirements

Applications in Cranes and Industrial Machinery

The coupling suits overhead cranes, hoists, metallurgy machinery, mining equipment, and conveyors. These industries often require frequent start-stop cycles and high safety standards. Therefore, the Brake Disc Jaw Elastic Coupling ensures smoother operation, longer machine service life, and reliable braking control.

Customization Options for Industrial Coupling

Customers can choose from various sizes and torque ranges. The brake disc is available in multiple diameters and thicknesses to match braking systems. Furthermore, our engineering team designs each coupling with strict material selection and precision machining.

Quality Assurance and Performance Testing

Before delivery, each coupling undergoes torque tests, dynamic balance checks, and braking efficiency tests. Consequently, the product guarantees stable performance in heavy-duty applications.
