Component Specifications

Definition
A precision mechanical coupling component designed to connect the drive shaft to the rotary hook assembly in industrial sewing or textile machinery. It ensures efficient torque transmission while accommodating minor misalignments and maintaining rotational stability under variable loads.
Working Principle
Operates by transmitting rotational torque from the motor-driven shaft to the rotary hook through a rigid or flexible coupling mechanism. The connection maintains constant angular velocity while compensating for axial, radial, and angular misalignments through precision bearings or flexible elements.
Materials
Typically manufactured from case-hardened alloy steel (AISI 4140/4340) or stainless steel (316/304) with surface treatments including nitriding or chrome plating for wear resistance. High-precision applications may use titanium alloys or engineered polymers for specific requirements.
Technical Parameters
  • Weight 0.5-3.5 kg
  • Maximum RPM 3000-6000
  • Connection Type Keyed, Splined, or Clamp-type
  • Torque Capacity 50-200 Nm
  • Shaft Diameter Range 15-40 mm
  • Operating Temperature -20°C to 120°C
Standards
ISO 9001, DIN 748, ISO 2768, DIN 7182
