摘要： The locus of the displacement of the centers of the balls of a ball bearing is made elliptical and the radial bearing rigidity of the ball bearing in one radial direction is made greater than the radial bearing rigidity in another radial direction orthogonal to the one radial direction, or at least one of the axial length of the portion on the inner diametral surface of the inner race of the ball bearing which is fitted to a shaft and the axial length of the portion on the outer diametral surface of the outer race of the ball bearing which is fitted to a housing is made 1/2 or less of the bearing width of the ball bearing, whereby the radial rigidity of a ball bearing device is made very small as compared with the radial rigidity in the prior art. As a result, the stability of a swing arm system can be enhanced and higher speed and higher accuracy of control become possible.

摘要： In the ball bearing inspection apparatus and method, the butting portion 7c of a skew drive shaft 7 rotatable coaxially with a spindle rotary shaft 1 is butted against steel balls 3 which are respectively held between the respective grooves of the inner ring 4b and outer ring 4a of a ball bearing 4 to be inspected, the spindle rotary shaft 1 is rotated while applying a pre-load to the outer ring 4a by a pre-load ring 5, and the skew drive shaft 7 is rotated while controlling the rotation speed of the skew drive shaft 7 in such a manner that the respective steel balls 3, which are being rotated on their own axes and around the spindle rotary shaft 1 due to the rotation of the spindle rotary shaft 1, is caused to make a skew movement due to the butting portion 7c. Therefore, physical quantities such as vibrations, sound pressures and the like generated from the ball bearing 4 to be inspected are measured in a condition that the respective balls 3 are making their respective skew movements in addition to their rotational movements on their own axes and around the spindle rotary shaft 1.

摘要： In superfinishing a Gothic-arch-shaped groove of a nut by using a superfinishing stone attached to the tip end of an oscillation arm while oscillating the superfinishing stone about the oscillation axis and, at the same time, moving the superfinishing stone in the longitudinal direction of the Gothic-arch groove, the oscillation axis is inclined by a predetermined angle with respect to the longitudinal direction of the Gothic-arch groove. The shape of the cross section of the Gothic-arch groove orthogonal to the oscillation axis is regarded as a single circular arc and, thus, both flanks of the Gothic-arch groove can be superfinished simultaneously.

摘要： In an annular member forming apparatus including: a forming roll rotatable in contact with an outer cylindrical surface of an annular workpiece; a mandrel relatively movable towards and away from the forming roll in contact with an inner cylindrical surface of the workpiece; and an outside diameter detecting device for detecting an outside diameter of the workpiece which is to be worked, the apparatus further includes a moving device for moving relatively the forming roll and the mandrel and for pressing the workpiece by the forming roll and the mandrel moved towards each other to subject the workpiece to rough rolling and to finish rolling. The moving device includes a retracting device for correcting an elastic deformation of the forming roll, the mandrel and the moving device occurring during the rough rolling, for a switching time from the rough rolling to the finish rolling by an output signal from the outside diameter detecting device. The moving device is moved backwardly away from the mandrel by a distance corresponding to a difference between amounts of elongation which are due to a rolling load during the rough rolling and due to a rolling load during the finish rolling for the switching time.

摘要： A ball polishing method includes the steps of rotating one of two plates through use of a rotating mechanism while balls are sandwiched between the plates, pressing one of the two plates against the other plate via a guide slide mechanism for guiding one of the two plates to the other plate by means of a pressing mechanism, and polishing the balls while the pressing force is regulated through use of a pressing force control mechanism. The method is further provided with rotary support means for supporting the rotating mechanism and guide support means for supporting the guide slide mechanism, and at least one of them utilizes hydrostatics. By virtue of this method, a machining pressure can be controlled with a high degree of accuracy, and the accuracy of polishing of balls can be improved.
