摘要： PROBLEM TO BE SOLVED: To prevent vibration and noise from occurring by minimizing the wear of separators in a rolling bearing.
SOLUTION: In this rolling bearing having the separators 5 and 6 installed between rolling elements 3 and 3, both the separators 5 and 6 are formed of a solid lubricant, and at least one of the separators 5 and 6 is formed so that a groove-like recessed face 5d is formed in a side face part in contact with the rolling elements 3 starting at the axial one end thereof toward at least the center part thereof. By this, since the separator 5 having the groove-like recessed face 5d can be inserted for assembly into clearances between the rolling elements 3 and 3 along the axial direction without being caught even if the clearances are small, the clearances between the rolling elements 3 and the separators 5 and 6 can be reduced. Also, a contact between the rolling elements 3 and the separator 5 is brought into a line contact or a contact similar to the line contact.

摘要： PROBLEM TO BE SOLVED: To provide a ball bearing which can maintain a smooth rotation for a long time without increasing a torque even when the number of separators arranged between raceways is large.
SOLUTION: In the ball bearing having balls 3 and cylindrical separators 4 alternately arranged in the peripheral direction between the raceways for rolling elements, the length L of the separators 4 in its longitudinal direction is formed so as to be 1.3 to 2.0 times as long as the diameter D of the balls 3. By this configuration, the separators 4 do not tilt in the peripheral direction even when forces are applied to the separators 4 from balls 3, 3 arranged next to both sides of the separators in the peripheral direction, and as a result, the resistance for the rotation of an inner race relative to an outer race is prevented. Further, the corners 4a, 4a at both ends of the separators 4 in its longitudinal direction are chamfered, and a recess 4c in the peripheral direction having the shape nearly equal to the curve of the bottom of an inner race side raceway groove 2a is formed at the central portion of the peripheral surface of the separators. By this configuration, the local wear due to the sliding of the separator with the inner race and the outer race can be prevented.

摘要翻译：要解决的问题：即使当设置在滚道之间的分离器的数量大时，也可以提供能够长时间保持平稳旋转而不增加转矩的滚珠轴承。＆lt; P＆gt;解决方案：在具有滚珠3和圆筒形隔板4的滚珠轴承中，在圆周方向上在滚动元件的滚道之间交替布置，隔板4在其纵向上的长度L形成为1.3至2.0倍只要球3的直径D即可。通过这样的结构，即使在从分离器4的旁边配置的球3,3向周边方向施加力，也不会在圆周方向上倾斜，方向，从而防止内圈相对于外圈旋转的阻力。此外，隔板4的长度方向的两端的角部4a，4a被倒角，形成与内圈侧滚道槽2a的底面的曲线几乎相等的圆周方向的凹部4c 在分离器的外周表面的中心部分。通过这种构造，可以防止由于分隔件与内圈和外圈的滑动导致的局部磨损。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a ball bearing capable of smoothly maintaining rotation by reducing the rise of a rotating torque when balls are clogged even when the number of separators disposed in a rolling element raceway is large.
SOLUTION: Either of a spherical separator 4 and a columnar separator 14 having a diameter smaller than that of balls 3 is disposed in the same rolling element raceway for the balls 3 carrying the load of the bearing. By this, the bearing torque when the balls are clogged can be reduced more than that in a conventional bearing in which only the columnar separator 14 is disposed. As a result, even the number of the separators disposed in the raceway is large, the rise of the torque in rotating can be suppressed to maintain the smooth rotation of the ball bearing.

摘要翻译：要解决的问题：为了提供一种滚珠轴承，即使当设置在滚动体滚道中的分离器的数量大时，也可以通过减小滚珠堵塞时的转矩的上升来平稳地保持旋转。解决方案：具有小于滚珠3的直径的球形分离器4和柱状分离器14中的任何一个设置在承载轴承负载的滚珠3的同一滚动体滚道中。由此，与仅设置柱状分离器14的常规轴承相比，球体堵塞时的轴承转矩可以降低。结果，即使设置在滚道中的分离器的数量大，也可以抑制旋转中的转矩的上升，以保持滚珠轴承的平稳旋转。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a ball bearing, capable of maintaining smooth rotation without having increase in torque even when a large number of separators are disposed in a raceway.
SOLUTION: In this ball bearing, balls 3 and columnar separators 4 are alternately disposed in the circumferential direction in the raceway of a rolling element. Both end surfaces 4a of the separator 4 are tapered in mutually symmetric form to a center axis of the length of the separator in such a way that a plane of projection as seen in the axial center direction of the bearing is trapezoidal. In this constitution, even when balls are stuck in the bearing during rotation, the separator 4 is pressed on either one side toward an outer ring side raceway surface 1a or an inner ring side raceway surface 2a only, thereby they are prevented from becoming resistance to rotation between the inner and the outer rings.

摘要翻译：要解决的问题：为了提供一种滚珠轴承，即使在轨道中设置大量分离器的情况下，也能够保持平稳的转动而不增加扭矩。解决方案：在该滚珠轴承中，滚珠3和圆柱形分离器4在滚动体的滚道中沿圆周方向交替布置。分离器4的两个端面4a以分离器的长度的中心轴线相互对称的形式呈锥形，使得在轴承的轴向中心方向上看到的突起平面是梯形的。在这种结构中，即使在旋转期间将球粘附在轴承中时，隔板4仅在外圈侧滚道表面1a或内圈侧滚道表面2a的一侧被按压，从而防止隔离件内圈和外圈之间的旋转。版权所有（C）2006，JPO＆NCIPI
