Flexible Tyre Couplings

Flexible Tyre Coupling is a special type of flexible coupling that combines the displacement compensation capability of flexible couplings with the elastic properties of tire structures.

Flexible Tyre Couplings belong to the category of mechanical power transmission components, which compensate for the relative displacement between two shafts through the elastic deformation of the tire ring, including axial offset, radial offset, and angular offset. This type of coupling usually consists of two outer cones, a flange, a cover, a pressure plate, and a tire ring with an Ω - shaped cross-section.

Structural Characteristics

• Tire ring: The tire ring is the core component of the Flexible Tyre Coupling, which is bonded to the steel skeleton by vulcanization method and has high elasticity and the ability to compensate for relative displacement between the two axes.
  

• Outer cone sleeve and flange: The outer cone sleeve and flange are connected by bolts to form the main structure of the coupling. The outer ring of the flange has holes evenly distributed in the circumferential direction for connecting with the shaft.
  

• Cover and pressure plate: The cover and pressure plate are located on both sides of the outer ring plate of the flange, used to clamp the tire ring and ensure the stable operation of the coupling.

Function Characteristics

• Displacement compensation: Flexible Tyre Couplings can compensate for various relative displacements between two shafts, ensuring the smooth operation of the transmission system.
  

• Vibration control: Due to the elastic properties of tire rings, Flexible Tyre Couplings can reduce the vibration amplitude of the transmission system and improve the operational stability of the equipment.
  

• Simple structure: The Flexible Tyre Coupling has a relatively simple structure, does not require lubrication, and is easy to install, disassemble, and maintain.

Flexible Tyre Couplings are widely used in transmission systems with axial, radial, or angular offsets, especially in working conditions with stable loads and minimal impact. For example, in heavy equipment such as steel mills and cement machinery, Flexible Tyre Couplings can compensate for axial, radial, or angular offsets between two shafts, ensuring the normal operation of the equipment.

Advantages:

• Strong compensation capability: able to compensate for significant relative displacement between two axes.
  

• Good vibration control effect: effectively reducing the vibration amplitude of the transmission system.
  

• Simple structure and easy maintenance: no need for lubrication, relatively simple assembly, disassembly, and maintenance.

Disadvantages:

• Limited load-bearing capacity: Compared to some rigid couplings, its load-bearing capacity may be lower.
  

• Larger external dimensions: Due to the presence of tire rings, the overall size of the coupling may be larger.

Flexible Tyre Coupling is a mechanical transmission device with displacement compensation capability and vibration control effect, suitable for transmission systems with various relative displacements. When selecting and using, comprehensive consideration should be given to specific working conditions and requirements.
