Abstract
A machine element is guided for linear movement along an I-beam by means of two endless rows of rolling elements on each side of the beam. The raceways for the roll bodies under load extend along the inner edges of the flanges of the beam, the raceways being positioned so that the force action lines on the roll bodies in the two raceways on each side of the beam converge in a direction away from the respective side of the beam.
Claims15
In a device for linearly guiding a machine element along a beam, wherein the beam and machine element define paths for two endless rows of circulating roll bodies on each side of the longitudinal median plane of the beam, the improvement wherein said beam has a center section joining a pair of end flanges, each end flange extending laterally of the beam on both sides of said longitudinal median plane, said machine element being positioned adjacent said flanges, a separate roll path for roll bodies under load being formed between said machine element and the inner edge of each said flange, said roll paths being positioned so that the force action lines on said roll bodies in the two roll paths on each side of the longitudinal median plane converge in the direction away from the respective side of said longitudinal median plane.
