摘要： A linear motion guide unit is disclosed in which a slider moves relatively of and along a track rail by virtue of rolling elements of balls or rollers. The rolling elements are allowed to recirculate from a load raceway formed between the track rail and the slider to a non-loaded area composed of a turnaround formed in the slider to communicate with the load raceway, and a return passage formed in the slider to communicate with the turnaround. The return passage is encircled with a sintered resinous member of porous texture. Lubricant absorbed and held in voids in the sintered resinous member can be supplied over a prolonged period to the rolling elements, thereby lubricating the rolling elements to make the frictional resistance less, which might be encountered when the slider moves on the track rail, and ultimately helping ensure the improvement in durability.

摘要： A linear motion guide unit is disclosed wherein rolling elements are allowed to run smoothly through a turnaround and less subject to wear. Separators connected to elongated coupler members are allowed to travel ahead together with the rolling elements through a recirculating passage, which is composed of a load raceway, a return passage and turnarounds. The separator are each made unchanged in thickness at a limited zone over which a sliding contact point thereof with the associated rolling element changes place from S1 to S12 when the separator moves through the turnaround. The coupler member is made in the form of a flexible strip kept substantially constant in cross section throughout the overall length to bend uniformly with a fixed radius RB of curvature when moving in the turnaround. The coupler member in the turnaround travels along a curve having a radius RB of curvature, which is less than a radius RO of curvature of a locus of the center of the rolling element, but larger than a radius RS of curvature of a locus of the sliding contact point between the separator and the associated rolling element, which will change place from S1 to S12 when the separator moves through the turnaround.

摘要： A linear motion guide unit is disclosed wherein lubricant-containing members of sintered resinous components are fixed to core metals with either of mechanical means and adhesives whereby the lubricant-containing members may be kept in an accurate sliding contact with the raceway grooves on the track rail. Lubricating plate assemblies attached on end caps by bolts are each composed of the lubricant-containing member of sintered resinous component, core metal and dustproof cover. The lubricant-containing members are each fixed on the associated core metal with adhesives or with mechanical means such as claws, grasping fingers or the like, which are formed on the core metals. The core metals have rigidity sufficient to protect the lubricant-containing members from deformation, resulting in keeping the highly accurate sliding contact relation of the lubricant-containing members with the raceway grooves on the track rail.

摘要： A relatively movable unit with rolling elements, or balls, adapted for use in a linear motion guide unit or a ball nut screw assembly. The relatively movable unit has lubricating rings disposed between any adjoining balls to thereby lubricate the balls. In the linear motion guide unit employing this relatively movable unit, the balls are confined in raceways at the interfaces between a track rail and a slider, while the lubricating ring is arranged between the adjoining balls. The lubricating ring is provided therein with spherical pockets opened to each other through a window at the center of the ring. The lubricating ring may be produced by forming a mixture of lubricant of turbine oil with resinous material of ultrahigh molecular weight polyethylene powder in a mold under pressure, and heating the molded mixture under pressure.
