摘要： A rolling bearing provided with measures to suppress a rise in temperature. The rolling bearing comprises inner and outer races, a plurality of rolling elements 16 interposed between the inner and outer races, and a cage for retaining the rolling elements 16. On the use conditions that the direction of load is stationary to the outer/inner race and rotational with respect to the inner/outer race of the two races, the cage 17 is guided for rotation with outer/inner regions of its pocket surfaces in contact with the rolling elements 16. It is also intended to facilitate satisfactory lubrication by means of grease and to enhance the durability and life of the bearing. For that purpose, a bearing 21 incorporated into a main motor is arranged with both end faces adjoining end members 24 and 25 that have grease pockets 22 and 23 formed therein, respectively. The bearing 21 includes an outer race 27 whose bore surfaces 33 and 34 on its ribs 31 and 32 are flush with the inner peripheries 35 and 36 of the grease pockets 22 and 23 in the end members 24 and 25, respectively.
摘要翻译：一种具有抑制温度上升的措施的滚动轴承。滚动轴承包括内圈和外圈，插入在内圈和外圈之间的多个滚动元件16和用于保持滚动元件16的保持架。在负载方向固定到外/内圈的使用条件并且相对于两个座圈的内/外座圈旋转，保持架17被引导以与其凹部表面的与滚动元件16接触的外部/内部区域一起旋转。其还旨在通过以下方式促进令人满意的润滑：润滑脂，增强轴承的耐用性和使用寿命。为此，组装在主电动机中的轴承21被布置成两个端面分别邻接形成在其中的油脂袋22和23的端部构件24和25。轴承21包括外圈27，其外侧表面33和34在其肋31和32上分别与端部构件24和25中的油脂袋22和23的内周边35和36齐平。

摘要： A ball screw for a vacuum apparatus which includes a screw shaft having a spiral inner raceway formed on an outer peripheral surface thereof, a ball nut having a spiral outer raceway formed on an inner peripheral surface thereof, a plurality of balls disposed in a spiral space defined between the inner raceway and the outer raceway, and circulating members connecting ends of the spiral space to each other to define a continuous ball circulating passage. The plurality of balls are first balls formed of high polymer material containing polytetrafluoroethylene as a main component and second balls formed of either a metallic material or a ceramic material. The first balls circulate through the circulating passage together with the second balls. The second balls have lubricating films of crystalline polytetrafluoroethylene formed on the surface thereof.
