摘要： PROBLEM TO BE SOLVED: To solve the problems on a bearing, generally, a ball bearing which may be used in a vacuum atmosphere in the processes of manufacturing semiconductors, that it is difficult to endure bidirectional high load from the point of structural property, and on a conventional cross roller bearing that contact portions are fixed in severe environment or inconvenient dusting occurs. SOLUTION: The cross roller bearing comprises an inner ring having a V-groove in the outer diameter, an outer ring having a V-groove in the inner diameter, and rollers arranged in the V-grooves of the inner ring and the outer ring via a spacer retainer in an alternately crossing manner. Spacers are provided on the tops and the bottoms of the rollers which contact the V-grooves via the spacers. In the cross roller bearing, the tops and the bottoms of the rollers have no direct contact with the V-grooves of the inner ring and the outer ring, and so the contact portions are less fixed thereto and inconvenient dusting less occurs. Thus, the cross roller bearing can be used even in a vacuum atmosphere. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题为了解决轴承方面的问题，一般来说，可以在制造半导体的过程中在真空气氛中使用的滚珠轴承，从结构上难以忍受双向高负载并且在传统的交叉滚子轴承上，接触部分在恶劣环境中固定或发生不方便的除尘。解决方案：交叉滚子轴承包括外圈具有V形槽的内圈，内径具有V形槽的外圈和布置在内圈的V形槽中的辊和外圈以交替交叉的方式通过间隔件保持器。在通过间隔件接触V形槽的辊的顶部和底部上设置有间隔件。在交叉滚子轴承中，辊的顶部和底部与内圈和外圈的V形槽没有直接接触，因此接触部较少固定在其上，并且不太方便地除尘。因此，即使在真空环境中也可以使用交叉滚子轴承。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a radial-needle-shaped roller bearing and a pinion shaft which enable the securing of smooth rolling of a roller. SOLUTION: A spacer 53 is arranged at the midsection of a shaft so that the roller is not rolled to the midsection in the axis direction of the shaft where the amount of the bending of the shaft is maximized. Then a retainer 52 and the roller 51 (a gauge and a roller) are arranged on both sides of the shaft. Since the amount of the bending of the shaft in lines on both its sides does not become as large as that on its midsection, the smooth rolling of the roller is not interfered with.

摘要： PROBLEM TO BE SOLVED: To provide a spacer ball type rolling mechanism which is improved in rigidity compared with a conventional spacer ball type rolling mechanism and reduces noise by achieving high accuracy.
SOLUTION: A ball screw mechanism is provided between a screw spindle 11 and a nut 12. Spacer balls 15 retained by a spacer ball retainer 14 are arranged between effectively load supporting steel balls 13 of the ball screw. Each retainer 14 has spherical hollow space retaining portions 14a formed to hold the spacer balls 15. Both sides of the spacer ball 15 retained inside the spherical hollow space retaining portion 14a are exposed from the retainer 14 and are brought into contact with the steel balls 13 on its both sides. Further, the outside dimensions of the spacer ball retainer 14 are determined such that the rotation center of the spacer balls 15 approximately coincides with the circulation trajectory of the rotation center of the effectively load supporting steel balls 13.
