    • PROBLEM TO BE SOLVED: To provide a highly efficient and highly reliable hermetic compressor, by preventing abrasion of an upper race and an upper race seating surface and abrasion of a lower race and a thrust sliding part, when operating the hermetic compressor.
      SOLUTION: The occurrent of abrasion in a contact part between the upper race 276 and a bore plane 266 and abrasion in a contact part between the lower race 278 and the thrust sliding part 230, is prevented by preventing the upper race 276 and the lower race 278 from rotating by being pulled by a ball 272, since the ball 272 rolls on the upper race 276 and the lower race 278 without sliding, by arranging the upper end 286 of a rotor 206 higher in the axis 228c direction than an upper end surface 253 of a stator 204 so that magnetic attraction force generated in the rotor 206 becomes the direction for sandwiching a thrust ball bearing 270 by the thrust sliding part 230.

    • 要解决的问题:当操作密封式压缩机时,通过防止上部座圈和上部座椅座面的磨损以及下部座圈和推力滑动部件的磨损来提供高效和高度可靠的密封式压缩机。 解决方案:通过防止上部座圈276和下部座圈276和下部座圈278之间的接触部分中的上部座圈276和孔面266之间的磨损以及下部座圈278和推力滑动部件230之间的接触部分中的磨损, 下座278由于被球272拉动而旋转,因为球272通过将转子206的上端部286布置在轴线228c方向上比上侧端部286更方向,而不会滑动而在上座圈276和下座圈278上滚动。 定子204的上端面253使得在转子206中产生的磁吸引力成为推力滑动部230夹持止推球轴承270的方向。(C)2009,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a rolling bearing mechanism making a pre-load providing function and a damping function compatible.
      SOLUTION: An intermediate ring 12 is inserted into an outer side in the radial direction from an outer ring 8 of a bearing 3 and an inner side from a housing 11 in play. A channel 13 is provided on an inner side of the intermediate ring 12 to hold adhesive lubricant between the intermediate ring 12 and the outer ring 8. A mechanical damper 16 as a damper member is fitted between the intermediate ring 12 and the housing 11. Pre-load is given to the outer ring 8 in the direction of central axis of the bearing 3. When the rolling bearing mechanism is constituted as mentioned above, pre-load is properly transmitted to the outer ring 8 without being absorbed by the damper member 16. A damper member 23 functions so as to damp vibration transmitted to the intermediate ring 12 from the bearing 3. Consequently, this rolling bearing mechanism damps vibration of the shaft by the damper members while applying proper pre-load continuously to support the shaft rotating at ultra-high speed.
