摘要： A surface shape evaluation method for a spherical body comprising the steps of: providing a support hole having a smaller diameter than the spherical body and having a curved bearing surface formed on its opening to have a curvature substantially equal to the curvature of the surface of the spherical body, providing a rotation drive arm for transmitting only a rotation component to the spherical body, providing a vibration sensor having a probe with a flat tip end, rotating the spherical body on a predetermined center axis and on the opening, such that one portion in the radial direction of the spherical body comes into contact with the curved bearing surface while the portion opposite to the one portion in the radial direction of the spherical body comes into contact with the tip end of the rotation drive arm, abutting the flat tip end of the probe of the vibration sensor to a surface portion of the spherical body located on a hypothetical flat surface which is orthogonal to the center axis and passes through the central point of the spherical body to detect the surface shape from the surface portion as vibration amounts, from which the results are through a sampling process and an adding and averaging process in harmonization with rotation velocity of the spherical body, and a frequency analysis process are evaluated as a numerical value e.g. of at least displacement.

摘要： In a rolling bearing including an inner race; an outer race; a plurality of rolling elements rollingly arranged between the inner race and the outer race; and a cage holding the rolling elements, the cage has an annular shape and a plurality of pockets which are formed at plural positions in a circumferential direction of the cage, in which each of the pockets has an opening peripheral portion which is curved to a direction of increasing a distance from a center of the rolling elements. The opening peripheral portion forms a chamfered face or a convex face. The rolling bearing can sufficiently ensure the lubrication of sliding contact portions between the cage and rolling elements so that vibrations and noises of the rolling bearing are lowered.

摘要： The frequencies generated based on the undulations existing on the inner and outer ring raceways 8, 10 and on the rolling surface of the balls 11, 11 are out of coincidence with the rotational frequency itself of the rotation member supported by the rolling bearing, and with a frequency component which is a multiple of the rotational frequency, or kinds of frequencies generated due to the undulations are out of coincidence with each other in the natural frequency domain of a rotation system which is a rotation supporting portion having the rolling bearing incorporated therein, whereby without using a special grease, the self-excited frequency of the rolling bodies hardly grows to abnormal vibration, and a rolling bearing having sufficient durability and causing no abnormal vibration and noise even if used at low temperature is realized.

摘要： The pocket surface of a pocket with a ball stored therein has a pair of first pocket surfaces respectively formed inside a pair of pawls and a second pocket surface situated between the two first pocket surfaces. The second pocket surface is formed as a spherical-shaped concave surface having a radius of curvature the center of curvature of which is the rotation center of the ball in a no-load state. Each of the first pocket surfaces has a center of curvature shifted from the center of curvature of the second pocket surface toward the opposite side to the entrance (opening) of the pocket by an axially shifting quantity h1, and each of the first pocket surfaces is formed, starting from the present center of curvature, as a spherical-shaped concave surface with its radius of curvature set larger than the radius of curvature of the second pocket surface.

摘要： There is disclosed a device for detecting damage on rotators or rotary bodies such as for example ball bearings having rolling elements. A mechanical vibration or sound produced periodically due to damage on the rotator when it is rotated is converted into an electric signal. In order to identify such damage on the rotator by utilizing the periodic characteristic of said electric signal, a peak detector is provided for detecting a peak value of said electric signal, holding the detected peak value for a fixed period, and being reset to a base level by a reset signal.
