WIPO Patent Application WO/2016/017351
Kind Code:
A1
Abstract:
This cycloidal speed reducer is provided with an input shaft (25), which has an eccentric section (25a, 25b), and roller bearings (37, 37) that rotatably support the input shaft (25) with respect to an output shaft (28). The input shaft (25) is provided with a lubricating oil path (25c) extending in the axial direction therewithin, and a first oil supply hole (P1) that extends in the radial direction and supplies the lubricating oil flowing through the lubricating oil path (25c) to roller bearings (41, 41) that support a curved plate (26a, 26b). The roller bearings (37, 37) are loosely fitted to the input shaft (25), and the input shaft (25) further has a second oil supply hole (P2) that extends in the radial direction and of which the inner end opens at the lubricating oil path (25c) and the outer end opens at the fitting section (M1, M2) of the roller bearings (37, 37).
