Abstract: The interior space of a cup-shaped flexible externally toothed gear of a cup-type wave gear device is divided into a front interior space and a rear interior space by a partition mechanism. A lubricant is filled in the front interior space at the side of a wave generator, to which lubrication is required. The volume of the front interior space is set so that a necessary amount of lubricant is filled. Since the lubricant is not necessary to fill in the entire interior space of the flexible externally toothed gear, the amount of lubricant to be filled can be reduced.

Abstract translation: 杯式波轮装置的杯形柔性外齿轮的内部空间通过分隔机构分为前内部空间和后内部空间。 润滑剂填充在需要润滑的波浪发生器侧的前部内部空间中。 前部内部空间的容积被设定为填充必要量的润滑剂。 由于润滑剂不需要填充柔性外齿轮的整个内部空间，因此可以减少要填充的润滑剂的量。
