    摘要： A ball bearing includes an outer ring having at two outer raceways and an inner ring having two inner raceways. A plurality of balls is disposed in each of the two inner and outer raceways. The plurality of balls include load bearing balls and spacer balls. The spacer balls are disposed between the load bearing balls. Each of the load bearing balls has a single point of contact with each of the two inner and outer raceways. The load bearing balls are preloaded between the outer ring and the inner ring at predetermined force.

    摘要： In a ball screw device comprising a screw shaft and a nut which make relative movement to each other through a multiplicity of balls, as well as in a linear motion device comprising an outer member and an inner member which make the relative movements to each other through the multiplicity of balls, a spacer having two concave surfaces facing respectively to balls, is disposed between the balls adjacent to each other. A section of each of the concave surfaces of the spacer is formed of two circular arcs of which central positions deviate from each other to form a Gothic arch. The spacer has such a configuration that the balls adjacent to each other come into contact with outer edges thereof or portions vicinal to the outer edges. The spacer also has such a configuration that the balls adjacent to each other come into contact with at least three or more outer edge portions thereof or portions vicinal to the outer edges. The spacer may have a through-hole formed in a thinnest portion thereof.

    摘要： In the ball screw, a ball circulation tube 20 is formed to have such a shape that the movable amount of balls 15 in a first direction (X) intersecting at right angles to the axis of the tube 20 is larger than the movable amount of the balls 15 in a second direction (Y) intersecting at right angles to the first direction (X), and the ball circulation tube 20 is fixed to a nut 13 in such a manner that the outer surface 20a of the tube 20 extending in parallel with the first direction (X) is opposed to the outer surface of the nut 13. Accordingly, it is possible to provide a ball screw which can restrict variations in the torque of the ball screw caused by the mutual sliding movements of balls occurring within a ball circulation tube.

    摘要： This rolling bearing includes an inner race, an outer race, rolling members--either balls or rollers--disposed between these races and rotatably supporting them relative to one another, and generally cylindrical retainers disposed between these rolling members, each rolling on its two adjacent rolling members and keeping them apart. Each retainer has an axially central portion rollingly contacting with these two adjacent rolling members, a pair of circumferential grooves each near one of its ends, and a pair of disk shaped end portions each near one of its ends. These retainers are positioned by their disk shaped end portions rolling on the one radial sides of support rails defined on a pair of covers mounted each at one axial end of one race, and by their grooves being engaged over the other radial sides of free rings each at one bearing axial end. The retainers either may roll on the radially outer sides of the rails and on the radially inner sides of the rings, or vice versa. The covers may be mounted to the inner or outer race. Radial play may be available for the retainers between the rails and rings. The center line of each retainer and the locuses of symmetry of the two adjacent rolling members may be coplanar. The thickness of the rings may be greater remote from where they contact the grooves of the retainers than proximate thereto. A device may be provided for impelling lubricant through the space between the races.
