Beam couplings for robotics

The multiple-beam pattern allows Ruland couplings to accommodate higher amounts of parallel misalignment than single beam couplings, while also allowing for high angular misalignment and axial motion.

Medical and surgical robots often combine a stepper or servo motor to a lead screw or encoder requiring a zero-backlash coupling for precise motion control. These systems have limited torque requirements; however, they may need high responsiveness and flexibility making a beam coupling a suitable choice. Ruland’s four-beam style couplings (P- and MW-series) have a more compact design that is paired best with light-duty applications such as servo motor to encoder connections.

The six-beam style coupling (F-series )has increased torque capacity and is well suited for light-duty power transmission applications such as connecting a motor to a lead screw.
