The Gear Flex Couplings – RLZ Series are high-performance couplings designed for high torque transmission, precision alignment, and reliable operation in heavy-duty industrial applications. These couplings utilize crowned gear teeth with precision-machined hubs and sleeves, enabling efficient torque transfer while accommodating misalignment.
Engineered for durability and performance, gear couplings are ideal for high-speed, high-load, and continuous-duty applications, where strength, reliability, and long service life are critical.
Capable of transmitting very high torque loads, making them suitable for heavy-duty machinery.
Delivers high torque in a relatively compact size compared to other coupling types.
Crowned gear teeth allow angular, parallel, and axial misalignment, ensuring smooth operation.
Precision gear design ensures uniform load distribution and reduced wear, extending operational life.
Minimal power loss due to positive mechanical engagement of gear teeth.
Designed to perform reliably under high rotational speeds and continuous operation.
Gear sleeves and seals can be serviced or replaced, reducing maintenance costs.
Construction & Working Principle
Components:
Gear Hubs:
• External gear teeth hubs made from high-strength alloy steel
Gear Sleeve / Outer Ring:
• Internally toothed sleeve with crowned gear profile
Sealing Arrangement:
• Retains lubricant and protects against contaminants
Lubrication System:
• Grease or oil lubrication for smooth gear engagement and wear reduction
Working Principle:
Torque is transmitted through the meshing of external hub teeth and internal sleeve teeth. The crowned gear profile allows misalignment while maintaining smooth engagement. Proper lubrication ensures reduced friction, minimized wear, and efficient operation.
