Title:
POWER TRANSMISSION MECHANISM FOR WORKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/113541
Kind Code:
A1
Abstract:
Disclosed is a power transmission mechanism for a working device, in which the lubrication performance is enhanced by providing lubrication at any location. A first eccentric cam (13) and a second eccentric cam (14) are respectively provided at a phase offset of 180º in the direction of rotation on both faces of a driven gear (12) which meshes with a drive gear. The driven gear (12) has a configuration in which a plurality of gear plates (50 – 55) are stacked in the thickness direction. Through-holes (50a – 55a) are formed in the plane of the gear plates (50 – 55), and each gear plate (50 – 55) is welded in such a way that the through-holes (50a – 55a) communicate with a phase offset. By means of this, the through-holes (50a – 55a) open onto a different phase plane on either surface of the driven gear (12).
