Component Specifications

Definition
A mechanical device used in paper machine reel spools to connect the drive motor shaft to the spool shaft, enabling torque transmission while accommodating minor misalignments, reducing vibration, and protecting equipment from overload. It ensures smooth rotation during paper winding operations.
Working Principle
Transmits rotational force (torque) from the motor to the reel spool shaft through flexible or rigid elements, compensating for axial, radial, and angular misalignments to maintain efficient power transfer and reduce mechanical stress.
Materials
Typically made from high-strength steel (e.g., AISI 4140), stainless steel (e.g., 316L) for corrosion resistance, or alloy steel with elastomeric or metallic flexible inserts.
Technical Parameters
  • Max Speed 1500-3000 rpm
  • Bore Diameter 50-150 mm
  • Torque Capacity 500-5000 Nm
  • Operating Temperature -20°C to 80°C
  • Misalignment Tolerance ±0.5° angular, ±1 mm parallel
Standards
ISO 9001, DIN 740, ISO 14691

Frequently Asked Questions

What is the primary function of a drive coupling in a paper machine reel spool?

It transmits torque from the motor to the spool shaft while accommodating misalignments and dampening vibrations to ensure smooth paper winding.

How often should drive couplings be inspected in paper manufacturing?

Inspect every 6-12 months or per manufacturer guidelines, checking for wear, misalignment, and lubrication to prevent downtime.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
