摘要： The present invention provides a transmission unit that can realize a high speed-shifting ratio, can realize reduced size, low cost and low noise, and is also capable of limiting slip loss. Outer peripheral surfaces of a small diameter rolling element and a supplementary rolling element are brought into contact with an outer peripheral surface of a large diameter rolling element. The supplementary rolling element is arranged at an almost opposite side to the small diameter rolling element, thus enclosing the large diameter rolling element between the small diameter rolling element and the supplementary rolling element. An inner peripheral surface of the pressure adjustment ring is brought into contact with the outer peripheral surface of the small diameter rolling element and the outer peripheral surface of the supplementary rolling element, and is supported by them. If the small diameter rolling element rotates, the pressure adjustment ring rotates by means of the large diameter rolling element and the supplementary rolling element. If load is applied to rotation of the large diameter rolling element, the pressure adjustment ring is made eccentric. In this way, the small diameter rolling element receives pressing force toward an inner side in the radial direction of the large diameter rolling element, from the pressure adjustment ring.
摘要翻译：本发明提供一种能够实现高速变速比的传动单元，能够实现尺寸减小，成本低，噪音低，并且还能够限制滑动损失。小直径滚动元件和辅助滚动元件的外周表面与大直径滚动元件的外周面接触。辅助滚动元件布置在与小直径滚动元件几乎相反的一侧，从而将小直径滚动元件与辅助滚动元件之间包围大直径滚动元件。压力调节环的内周面与小直径滚动体的外周面和辅助滚动体的外周面接触，并被其支撑。如果小直径滚动元件旋转，则压力调节环通过大直径滚动元件和辅助滚动元件旋转。如果对大直径滚动体的旋转施加载荷，则压力调节环偏心。以这种方式，小直径滚动元件从压力调节环向大直径滚动元件的径向内侧承受挤压力。

摘要： A refrigerating machine oil composition for vapor compression type refrigerating machines is disclosed which can be used with either of HCFC refrigerants and HFC refrigerants. The inventive machine oil composition comprises a polyol ester (ester compound) as a base oil. Furthermore, the base oil contains from 1.0 to less than 5.0% by weight of a phosphate, from 0.1 to 2.0% by weight of an alkyl phosphorothionate and/or an aryl phosphorothionate, and from 0.05 to 2.0% by weight of an epoxy compound. The composition is free from sludge formation and insufficient lubricity, which are drawbacks of the polyol ester, due to the synergistic effect of these additives. On the other hand, the inventive composition provides the desirable properties of a polyol ester base oil, namely, good compatibility with refrigerants, high electrical insulating properties, and low hygroscopicity.
