Problems solved by technology

[0014] Moreover, since the outer ring uses sintered parts, if it is used for a long time, the base oil component of the grease sealed in the wedge-shaped space of the outer ring will be absorbed by the porous part of the sintered part, and the viscosity of the lubricating oil will increase. Propensity
As a result, during long-term use, the viscosity of the lubricating oil becomes high, and when the shaft meshes with the rotating body, the responsiveness of the rotating body deteriorates, and poor meshing may occur.

Abstract

Provided is a one-way clutch which can prolong the service life of the felloe or leaf spring of a one-way clutch and a shaft, and prevent bad engagement between the shaft and a rotating body. The ring part of the leaf spring is located in a recess from the felloe of a sintering part; the pressing part of the leaf spring is located in a sphenoid space and presses the rotating body of the sphenoid space of the felloe. The inner of the recess of the felloe is provided with a footpace for preventing a cover member from contacting with the leaf spring so as to support the cover member, ensuring that the ring part of the leaf spring is a gap bending freely and increasing the effective length of the spring of the leaf spring. When rotating towards a narrow part from the wide width part of the sphenoid space, the shaft rotates integratedly with the felloe; while rotating to the wide width from the narrow part of the sphenoid space, the shaft is idle.

Description

technical field [0001] The present invention relates to a one-way clutch that transmits rotational force in only one direction. Background technique [0002] A one-way clutch is a clutch that transmits rotational force in only one direction of a shaft to an outer wheel (for example, refer to Patent Document 1). When the shaft rotates in the direction capable of transmitting the rotational force, the rotating body is pressed by the plate spring and becomes engaged, thereby transmitting the rotational force of the shaft to the outer ring, and the rotating body is provided between the wedge-shaped space formed on the outer ring and the shaft. On the other hand, when the shaft rotates in the opposite direction, the rotating body moves to the wide part of the wedge-shaped space, whereby the meshing state of the rotating body is released and the rotation of the shaft becomes idling, so that no rotational force is transmitted to the outer wheel. . Such one-way clutches are used i...
