The Brake Wheel Plum Blossom Elastic Coupling is a specialized coupling that combines the functionality of a brake wheel with the characteristics of a plum blossom elastic coupling. It not only efficiently transmits torque but also provides vibration damping, cushioning, and compensation for shaft misalignment. By integrating a brake wheel with a plum-shaped elastic element, this coupling ensures stability under dynamic load changes and enables effective braking, making it suitable for machinery requiring smooth operation and emergency stopping.

Brake wheel plum elastic coupling Main Features:

  1. Structure: The Brake Wheel Plum Blossom Elastic Coupling consists of two metal hubs, a plum-shaped elastic element, and a brake wheel. The brake wheel is typically mounted on one end of the coupling and applies braking force through a braking system. The plum-shaped elastic element, made from high-elastic materials such as rubber or polyurethane, offers excellent cushioning and vibration damping. The metal hubs are connected to the elastic element using bolts, ensuring stable operation of the coupling.
  2. Working Principle: This coupling transmits power from the driving shaft to the driven shaft via the plum-shaped elastic element. While transmitting torque, the elastic element absorbs vibrations and shock loads effectively, reducing wear and noise in the transmission system. Simultaneously, the brake wheel applies braking force through the braking system, allowing the shafts to decelerate or stop quickly when needed.
  3. Applications: The Brake Wheel Plum Blossom Elastic Coupling finds widespread use in scenarios requiring precise control and high safety, such as cranes, elevators, and conveyors. It is particularly well-suited for applications demanding emergency stops or the ability to withstand significant impact loads. This coupling is ideal for equipment requiring both reliable power transmission and effective braking and damping capabilities.
  4. Design Advantages: This coupling not only ensures efficient power transmission but also minimizes vibrations and shocks through its elastic element, enhancing system stability. Furthermore, its brake wheel design enables rapid braking when necessary, ensuring safe operation of the machinery.

Advantages:

  • Vibration Damping and Cushioning: The plum-shaped elastic element absorbs vibrations and shock loads effectively, reducing wear on the equipment and extending its service life.
  • Emergency Stopping Capability: The brake wheel provides rapid braking when required, facilitating quick deceleration or emergency stops.
  • Strong Adaptability: This coupling accommodates certain axial, angular, and radial misalignments, making it suitable for systems with installation errors.
  • Smooth Operation: Its elastic design reduces noise and vibration during operation, ensuring stable and quiet performance.

Disadvantages:

  • Limited High-Temperature Resistance: The elastic element, often made of rubber or polyurethane, performs poorly in high-temperature environments, making it more suitable for normal or low-temperature conditions.
  • Moderate Load Capacity: Compared to some metal couplings, the Brake Wheel Plum Blossom Elastic Coupling has relatively lower load-bearing capacity, limiting its application to medium and light-load systems.
  • Wear and Tear: The elastic element may wear out over time, requiring regular inspection and replacement.

Additionally, the MLLZ Brake Wheel Plum Elastic Coupling has a wide operating temperature range, from -35°C to +80°C, and the nominal torque transmission range is from 250 to 31,500 Nm, with a permissible speed range of 950 to 4250 r/min. This coupling offers a variety of specifications and sizes to meet different application needs.
