June 30, 2023 Beam Couplings from Ruland for Robotics Applications

Ruland beam couplings are ideal for surgical, warehouse, and industrial robotics.

Marlborough, Massachusetts. Ruland beam couplings are ideal for surgical, warehouse, and industrial robotics due to their increased torque and torsional stiffness and ability to accommodate all forms of misalignment. Ruland manufactures four-beam couplings for encoders and six-beam couplings for light-duty power transmission, such as connecting a stepper or servo motor to a lead screw. This allows robotic designers to design a standard beam coupling into most systems.

Ruland machines beam couplings from a single piece of aluminum or stainless steel for a zero-backlash design and maintenance-free service life. Multiple sets of spiral cuts enable Ruland beam couplings to handle all forms of misalignment – angular, parallel, axial motion, and complex – through frequent starts and stops. The multiple-beam design also allows for higher torque and torsional stiffness than commodity-style single-beam couplings. Ruland manufactures beam couplings in 7075 aluminum for low inertia and 303 stainless steel for increased torque capacity.

Ruland F-Series six-beam couplings have two sets of three beams allowing them to maintain accuracy, repeatability, and reliability in robotic systems. They have larger body sizes than comparable four-beam couplings for increased torque and torsional stiffness. F-series clamp-style beam couplings are supplied with Ruland’s proprietary Nypatch anti-vibration hardware to prevent screws from loosening during operation

Ruland P- and MW-Series four-beam couplings have two sets of two beams for increased flexibility and reduced bearing loads compared to the six-beam style. They also have shorter lengths, making them suitable for space-restricted applications commonly found in encoders. MW-Series couplings have nominal metric dimensions to better fit with systems with metric components.

Ruland offers beam couplings with a clamp or set screw hub attachment with inch, metric, and inch-to-metric combinations ranging from 1/8 inch to ¾ inch and 3 mm to 20 mm. They are manufactured in Ruland’s Marlborough, Massachusetts factory under strict controls using proprietary processes. Non-standard designs such as anodizing, non-standard bore sizes, and special tolerances are available upon request.

Beam couplings are part of Ruland’s complete zero-backlash coupling line, including rigid, bellows, disc, jaw, oldham, controlflex, and slit couplings. Full product information, 3-D CAD files, and additional technical specifications are available at ruland.com.
