Outer and Inner Teeth Clutch Liner – Description

Outer and inner teeth clutch liners are specialized friction components used in clutch assemblies where the friction lining is designed with teeth either on the outer circumference (outer teeth) or on the inner circumference (inner teeth). These teeth engage with matching grooves or splines on the clutch housing or shaft, enabling torque transmission while providing secure, slip-free operation.

Key Features:

• Outer Teeth Clutch Liner:

  • The friction lining has teeth on its outer diameter.

  • These teeth mesh with the clutch drum or housing, which has matching grooves.

  • Common in multi-plate clutches where the clutch plates are stacked inside the drum.

• Inner Teeth Clutch Liner:

  • The friction lining has teeth on its inner diameter.

  • These teeth engage with the clutch hub or shaft splines.

  • Often used on the clutch plates that are mounted on the input or output shaft.

• Material:
  Made from high-friction, wear-resistant compounds such as organic composites, semi-metallic blends, or sintered materials, designed to withstand heat and mechanical stress.

• Precision Machined Teeth:
  The teeth are carefully shaped and dimensioned for tight engagement to minimize backlash and ensure smooth power transmission.

Functions:

• Torque Transmission:
  Teeth allow the liner to transfer rotational force from the clutch plate to the shaft or housing without slipping.

• Heat and Wear Resistance:
  Liner materials resist degradation under frictional heat and mechanical wear during clutch engagement and disengagement.

• Alignment and Stability:
  Teeth ensure proper alignment of clutch components, reducing vibration and noise.

Applications:

• Automotive multi-plate clutches (motorcycles, race cars)

• Industrial machinery clutches and brakes

• Agricultural and construction equipment

• Heavy-duty transmission systems requiring compact and efficient torque transfer

Advantages:

• Secure mechanical engagement prevents slippage

• High durability under repeated clutch cycles

• Smooth power transfer with minimal noise

• Customizable for different torque and speed requirements
