Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of a compressor without increasing material cost from present cost by reducing leak loss while restraining friction resistance of a sliding surface of a roller end surface.
SOLUTION: Area filled with high pressure oil on a lower end surface is set same as or greater than area filled with high pressure oil on a roller upper end surface. Force pushing up the roller from a lower side to an upper side is generated thereby, and leak loss can be reduced since gaps of roller both end surfaces are in an equalizing direction. Even if the roller does not rise, sever slide is avoided and wear, seizure and the like are reduced since holding force from the upper side to the lower side is not added by pressure and the roller touches a lower bearing by only self weight.

解决方案：在下端面上装有高压油的区域设置在辊上端表面上与高压油填充区域相同或更大。 由此产生将辊从下侧向上推的力，由于辊两端面的间隙处于均匀方向，所以可以减少泄漏损失。 即使辊子不升高，也避免了滑动，并且由于从上侧到下侧的保持力不被加压而磨损，咬合等减少，并且滚子仅通过自重而接触下部轴承。 版权所有（C）2010，JPO＆INPIT
