Title:
BEARING PART STRUCTURE AND ECCENTRIC OSCILLATION TYPE GEAR SYSTEM WITH THE BEARING PART STRUCTURE
Document Type and Number:
Japanese Patent JP2007240003
Kind Code:
A
Abstract:
To easily supply a lubricant to a needle-like roller 48 in a semi-sealed space 51 by a simple structure.
A lubricant passage 53 having one end connected with the semi-sealed space 51 and opened at a position radially overlapping with the needle-like roller 48 is formed in a crankshaft 35. Therefore, a large centrifugal force based on the rotation of the crankshaft 35 acts on the lubricant located in the vicinity of the one-end opening of the lubricant passage 53. The lubricant stored in a gear system is consequently carried in the lubricant passage 53, drawn from the one-end opening, and supplied to the needle-like roller 48 in the semi-sealed space 51.
