Poly Gear Couplings (RPS Series)

Product Overview

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.

Key Features & Benefits

Split Sleeve Design

The two-piece (split) polyamide sleeve allows easy installation and replacement without moving connected equipment, reducing downtime significantly.
Maintenance-Free Operation

No lubrication required due to the use of polyamide gear sleeve, ensuring clean and cost-effective performance.
High Torque Capacity

Designed to handle moderate to high torque loads efficiently.
Excellent Vibration Damping

Polyamide material provides improved damping compared to traditional all-metal gear couplings.
Corrosion Resistant

Non-metallic sleeve offers excellent resistance to moisture, chemicals, and environmental conditions.
No Metal-to-Metal Contact

Reduces wear, noise, and extends service life.
Compact & Lightweight Design

Simplifies handling and installation, especially in space-constrained applications.

Construction & Material Options

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
• Easy installation without disturbing equipment alignment
• Maintenance-free with no lubrication required
• Lightweight and corrosion-resistant design
• Reduced noise and vibration
• Quick sleeve replacement minimizes downtime

Typical Applications
Poly Gear Couplings (RPS Series) are widely used in:
• Harvesting Machines
• Construction Machines
• Hydraulic Pumps

These couplings are ideal for applications requiring quick maintenance, reliable torque transmission, and reduced operational downtime.

Optional Variants & Customization
• Different polyamide grades for enhanced performance
• Custom bore and keyway configurations as per DIN / ISO standards
• Custom sizes for specific industrial applications
