The Poly Gear Couplings – RPS Series are high-performance torsional rigid curved tooth flange couplings designed to deliver efficient torque transmission with enhanced flexibility and maintenance-free operation. These couplings combine precision-machined metallic slit hubs with a polyamide (nylon) gear sleeve, offering a perfect balance between strength, damping, and ease of installation.
The RPS Series is especially suitable for applications where quick assembly, minimal downtime, and reliable performance are critical.
The two-piece (split) polyamide sleeve allows easy installation and replacement without moving connected equipment, reducing downtime significantly.
No lubrication required due to the use of polyamide gear sleeve, ensuring clean and cost-effective performance.
Designed to handle moderate to high torque loads efficiently.
Polyamide material provides improved damping compared to traditional all-metal gear couplings.
Non-metallic sleeve offers excellent resistance to moisture, chemicals, and environmental conditions.
Reduces wear, noise, and extends service life.
Simplifies handling and installation, especially in space-constrained applications.
Components:
Metallic Gear Hubs:
• External gear teeth hubs made from high-strength steel
Polyamide Gear Sleeve (Internal Teeth):
• Two-piece nylon sleeve that meshes with hub teeth and enables easy installation
Fastening Arrangement (if applicable):
• Ensures secure assembly of the split sleeve
Working Principle:
Torque is transmitted through the meshing of metallic hub teeth and polyamide sleeve teeth. The split sleeve design allows quick assembly, while the flexible polyamide material accommodates misalignment and absorbs vibrations, ensuring smooth and efficient operation.
Advantages
