    • PROBLEM TO BE SOLVED: To provide a compressor capable of preventing seizure between a rear shaft of a shaft and a rear bearing, by reducing a surface pressure between the rear shaft of the shaft and the rear bearing.SOLUTION: The diameter R2 of a rear shaft 12b of a shaft 12 is smaller than the diameter R1 of a front shaft 12a of the shaft 12. The rigidity of rear-side elastic sections 64 is less than the rigidity of front-side elastic sections 54. When this compressor is operated, the deflection of the rear shaft 12b is greater than the deflection of the front shaft 12a. However, the elastic deformation of the rear-side elastic sections 64 is capable of becoming larger than the elastic deformation of the front-side elastic sections 54. Thus, the surface pressure between the rear shaft 12b and the rear-side elastic sections 64 can be reduced, and seizure of the rear shaft 12b and rear bearings 60 can be prevented.
    • 要解决的问题:通过减小轴的后轴和后轴承之间的表面压力,提供一种能够防止轴的后轴与后轴承之间发生咬合的压缩机。 解决方案:轴12的后轴12b的直径R2小于轴12的前轴12a的直径R1。后侧弹性部64的刚性小于前侧的刚性, 当该压缩机被操作时,后轴12b的偏转大于前轴12a的偏转。 然而,后侧弹性部64的弹性变形能够变得大于前侧弹性部54的弹性变形。因此,后轴12b与后侧弹性部64之间的表面压力 可以防止后轴12b和后轴承60的卡住。 版权所有(C)2013,JPO&INPIT
