PURPOSE:To preform good lubrication even when a machine is in a low speed, by extending an oil pipe with the bottom part being immersed in lubricating oil in the axial direction of a wave generator engaging each gear of a flexing spline and a circular spline. CONSTITUTION:A reduction machine has a wave generator 12 engaging each gear of a circular spline fixed to a main unit 9 and a flexing spline 10 connected with an output shaft 11. The above machine, extending in the axial direction an oil pipe 14 consisting of a fine tube through the wave generator 12, immrse the bottom of a tilt part 14a of the oil pipe 14 in lubricating oil 15. Now if the wave generator 12 is driven, lubricating oil 15a accumulated in the tilt part 14a rises in the oil pipe 14 by centrifugal force by rotating the oil pipe 14, being allowd to flow out from the upper end. As a result, a ball bearing 13 and a gear part of said each spline 8, 10 are lubricated. In this way, the machine, even when it is in a low speed, can be well lubricated. |
