Brief: Explore what sets this solution apart in an easy-to-follow presentation. This video showcases the 3J-11J Gear Coupling, demonstrating its claw-type design that provides effective vibration damping and shock reduction. You'll see how it compensates for axial, radial, and angular displacement, and learn why its polyurethane construction offers superior wear resistance and a longer service life for air compressor OEM applications.
Related Product Features:
  • Claw-type surface-to-surface design provides protection with effective vibration and shock reduction.
  • Compensates for axial, radial, and angular displacement to avoid stress concentration.
  • Operates under extrusion pressure only, enabling it to withstand greater loads and offer better wear resistance.
  • Simple structure with stable performance and reliable operation for serious production lines.
  • Three-component structure for easy installation and maintenance in various environments.
  • Suitable for both horizontal and vertical installation in air compressor systems.
  • Elastic body isolates metal shaft hub contact, providing effective insulation without lubrication.
  • Manufactured with high-quality polyester or CSM/SBR for high tensile strength and oil resistance.
FAQs:
  • What temperature range can this polyurethane gear coupling withstand?
    This coupling is designed to operate effectively at working temperatures up to 120°C, making it suitable for demanding industrial environments.
  • How does the claw-type design benefit the coupling's performance?
    The claw-type teeth design with quincunx elastic body involute avoids stress concentration during installation deviations and effectively compensates for axial, radial, and angular displacement while providing vibration damping.
  • Is lubrication required for these gear couplings?
    No, the coupling's design includes a small protuberance pad on the elastic body that isolates metal shaft hub contact, providing effective insulation without requiring any lubrication.
  • What materials are used in manufacturing these couplings?
    They are manufactured by injection molding using high-quality polyester or CSM/SBR molds, providing excellent wear resistance, oil resistance, and high impact resistance.
