  • Precision bearings for robotic applications

    The distance between gears’ teeth often results in lost motion, decreased speed, and not precise positioning. To keep RDrive robot joints fast and accurate, a zero-backlash harmonic gearbox is used. Strain wave or harmonic gearbox consists of an outer fixed ring, an inner flexible ring, and an elliptical wave generator with steel ball bearings.

  • CSC 297 Robot Construction: Joints

    2009-2-27 · Abstract: This paper presents a novel approach to the modeling and identification of elastic robot joints with hysteresis and backlash. The model captures the dynamic behavior of a rigid robotic manipulator with elastic joints. The model includes electromechanical submodels of the motor and gear from which the relationship between the applied torque and the joint torsion is identified.

  • xiros® ball bearings from igus®

    xiros polymer ball bearings to DIN 625 do not need any external lubrication, are corrosion-resistant (if glass or plastic balls are used) and, during operation, are extremely quiet. This makes them a cost-effective alternative to metal ball bearings. Made from a mixture of tribo-polymers, the iglidur material plastic components are light, resistant to chemicals and non-magnetic.
