The Poly Gear Couplings – RPG Series are advanced flexible couplings designed to combine the high torque capacity of gear couplings with the maintenance-free benefits of elastomeric materials. These couplings utilize a polyamide (nylon) gear sleeve in combination with metallic hubs to provide efficient torque transmission, excellent damping, and reduced maintenance requirements.
Engineered for reliability and performance, RPG Series couplings are ideal for applications requiring high strength, smooth operation, and lubrication-free performance.
Polyamide gear sleeve eliminates the need for lubrication, reducing maintenance cost and effort.
Capable of handling Low to Medium torque capacity with efficient power transfer.
Polymeric sleeve provides better damping compared to traditional all-metal gear couplings.
Polyamide material offers high resistance to corrosion and environmental factors.
Reduced weight compared to metal gear couplings, enabling easy handling and installation.
Reduces wear, noise, and extends service life.
Simple assembly with quick replacement of the sleeve element.
Components:
Metallic Gear Hubs:
• Precision-machined external gear teeth hubs made from steel
Polyamide Gear Sleeve (Internal Teeth):
• High-strength nylon sleeve that meshes with hub teeth
Working Principle:
Torque is transmitted through the meshing of metallic hub teeth and polyamide sleeve teeth. The flexible sleeve accommodates misalignment while providing damping and eliminating the need for lubrication, ensuring smooth and efficient operation.
Advantages
• Maintenance-free with no lubrication required
• Lightweight and corrosion-resistant design
