Title:
ONE-WAY CLUTCH
Document Type and Number:
WIPO Patent Application WO/2019/176225
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a one-way clutch that is simple and easy to manufacture, is compact and lightweight, is resistant to breakage, and can prevent abrasion of an inner peripheral engagement surface and an outer peripheral engagement surface of a cam during high-speed idling. This one-way clutch (100) comprises an inner ring (10) and an outer ring (50), a cam mechanism (40), and side plates (30), (54). A cam (42) is disposed between the outer ring (50) and the inner ring (10) and between the side plates (30), (54). Spaces between the respective side plates (30), (54) and the cam (42) are filled with a lubricant. When the outer ring (50) rotates, the side plates (30), (54) rotate in the same direction and the cam (42) also rotates in the same direction as the outer ring (50) due to the viscosity of the lubricant, and as a result, no conventional retainer is required. Accordingly, failure due to breakage of the retainer does not occur, and therefore the clutch is resistant to breakage, has a simple structure, is easy to manufacture, and is compact and lightweight.
