Description

The Sling Coupling is a revolutionary concept for transmitting torque from the gear to the mill top in heavy-duty industrial applications. Designed to replace traditional square couplings and tail bars, the Sling Coupling consists of a driving and driven half, connected by flexible polyester slings. This innovative design allows the coupling to accommodate significant misalignment between the gear and the mill top roller, ensuring smooth power transmission and reducing mechanical stress.

The Sling Coupling directly connects the final speed reducer of the mill drive to the top roller, with the driving half secured to the square end of the speed reducer output shaft and the driven half attached to the square end of the mill’s top roller. The use of polyester slings provides flexibility, absorbing axial and radial misalignments without generating the high bending moments associated with traditional couplings. This results in enhanced mill performance, lower power consumption, and minimal maintenance.

Advantages

  • Enhances the Mill’s extraction performance. The typical tail bar obstructs the mill top roller from freely floating. The Multi Misalignment coupling does not constrain the top roller. With the top roller free-floating, the mill operates at the planned setting and optimal hydraulic pressure, resulting in increased efficiency.
  • If placed at the end of the milling process, the final bagasse moisture content will be lower.
  • Misalignment between the square end of the gear shaft and the top roller, either as a result of the Top Roller tilting or as a result of an initial alignment issue in installations where the Sling Coupling is entirely absorbed. As a result, the final gear receives no considerable lateral force or bending moment.
  • Mill torque and power usage are reduced.
  • Crown pinion and top roller breakage are entirely eliminated.
  • Negligible upkeep.

Key Features

  • Flexible design: Utilizes polyester slings to accommodate significant misalignments, ensuring smooth operation.
  • Direct connection: Links the mill drive’s final speed reducer directly to the mill’s top roller for efficient torque transmission.
  • Reduced mechanical stress: Eliminates the high bending moments and lateral forces caused by misalignments.
  • Improved mill performance: Allows the top roller to float freely, optimizing mill efficiency and reducing power consumption.
  • Low maintenance: Designed for long-lasting performance with minimal upkeep required.

Industrial applications

  • Sugar Industry: Specifically designed for sugar mills, the Sling Coupling enhances the extraction process, improves operational efficiency, and reduces power consumption.
  • Cane Processing Equipment: Ensures smooth torque transmission and mitigates mechanical stress in heavy-duty cane crushing operations.
