  • This invention relates generally to a method of producing a one-way clutch. More particularly, it relates to a method of producing a one-way clutch which includes a shaft member, an outer race disposed on an outer circumference side of the shaft member and having a plurality of pocket portions provided on an inner circumferential face thereof in such a manner as to be concave toward the outer circumference side, and a roller and a resilient member accommodated in each of the pocket portions .
  • a method of producing a one-way clutch which includes a shaft member, an outer race disposed on an outer circumference side of the shaft member and having a plurality of pocket portions provided on an inner circumferential face thereof in such a manner as to be concave toward the outer circumference side, and a roller and a resilient member accommodated in each of the pocket portions, the method comprising: a preparation step of providing a disk- shaped blank; a preforming step of performing cold presswork on the disk-shaped blank to reduce the thickness of the disk-shaped blank; a forming step of performing cold presswork on the disk- shaped blank subsequently to the preforming step to form a through-hole into which the shaft member is to be fitted and the pocket portions in the disk-shaped member to complete the outer race; and an assembling step of assembling the rollers and the resilient members into the pocket portions and fitting the outer race with the shaft member.
  • the one-way clutch production method is characterized in that cold presswork (forming step) is performed on a disk-shaped blank to produce an outer race.
  • cold presswork forming step
  • the outer race has retaining portions formed thereon for retaining the rollers and the resilient members so as not to come off from the pocket portions to the inner circumference side of the outer race.
  • FIG. 1 is a schematic sectional view of a one-way clutch according to an embodiment of the present invention
  • FIG.2 is an enlarged view showing a portion around a pocket portion of FIG. 1;
  • FIG. 3 shows side face of a disk-shaped blank for illustrating a preparation step in the one-way clutch production;
  • FIG. 4 shows the side face of the disk-shaped blank for illustrating a pre-forming step in the one-way clutch production

  • FIG.7 is an enlarged view showing a portion around a pocket portion of FIG. 6.
  • FIG.1 showing in section a one-way clutch 1 according to an embodiment of the present invention.
  • the one-way clutch 1 shown in FIG.1 comprises a shaft member 11, an outer race 12, rollers 13, resilient members 14, and a lid member 15.
  • the shaftmember 11 is a cylindrical member for transmitting a torque to the outer race 12.
  • the outer race 12 is an annular member metal and has a through-hole 12a formed at a center thereof for engaging with the shaft member 11, a plurality of pocket portions 21 (six in the illustrated embodiment) provided in an equidistantly spaced relation from each other in a circumferential direction on an inner circumferential face thereof in such a manner as to be concave toward the outer circumference side, and retaining portions 22, 23 (refer to FIG. 2) provided at edge portions of each of the pocket portions 21 in the circumferential direction in such a manner as to make the opening width of the pocket portion
  • an inclined face 21a is formed such that the distance between the concave face of the pocket portion 21 and the outer circumferential face of the shaft member 11 decreases toward one side in the circumferential direction (left side on the plane in
  • FIG. 2 shows a diagrammatic representation of FIG. 1 of FIG. 1.
  • Each of the rollers 13 is a cylindrical member provided corresponding to the inclined face 2la in the corresponding pocket portion 21 and is interposed between the shaft member 11 and the outer race 12 to transmit torque between them.
  • Each of the resilientmembers 14 is formed from, for example, an accordion spring formed by bending a plate-like member made of a metal and is provided so as to bias the corresponding roller 13 in the direction in which the distance between the corresponding inclined face 21a and the outer circumferential face of the shaft member 11 decreases.
  • the lid member 15 is a member for covering the outer circumferential face of the outer race 12 and the pocket portion 21.
  • each of the rollers 13 moves toward the R side of the corresponding pocket portion 21. Consequently, the roller 13 is bitten between the inclined face 21a of the pocket portion 21 and the outer circumferential face of the shaft member 11 to place the shaft member 11 and the outer race 12 into a mutually locked state. Consequently, the torque of the shaft member 11 is transmitted to the outer race 12 through the rollers 13.
  • each of the rollers 13 moves to the side opposite to the R side of the corresponding pocket portion 21 against the biasing force of the corresponding resilient member 14.
  • a method of producing the one-way clutch 1 is described.
  • the method of producing the one-way clutch 1 comprises the following steps: 1. Preparation Step
  • a metal blank such as a round bar is cut to provide a disk-shaped blank 31 from which the outer race 12 is to be formed (see FIG. 3) .
  • Step 1 cold presswork is performed on the disk-shaped blank 31 to reduce the thickness of the disk-shaped blank 31 approximately to the thickness of the outer race 12 after it is formed.
  • the cold presswork lines or swells on the surface of the skin of the disk face of the disk-shaped blank 31 can be reduced (refer to FIG. 4).
  • a metal die having a shape with which the through-hole 12a into which the shaft member 11 is to be fitted, the pocket portions
  • the resilient members 14 are assembled into positions of the pocket portions 21 of the outer race 12 at which the inclined faces 21a are not formed, and then the rollers 13 are pushed into the resilient members 14 at positions corresponding to the inclined faces 21a (refer to FIG. 6). Consequently, as shown in
  • the outer race 12 is produced by stamping (cold presswork) with a metal mold. Therefore, the number of man-hours can be reduced when compared with that of a conventional production method wherein a plurality of broaches are used. Further, since also the retaining portions 22, 23 can be formed simultaneously, the number of man-hours forworkingthe outer race 12 does not increase at all.
  • the rollers 13 and the resilient members 14 are retained so that they may not come off from the pocket portions 21 to the inner circumference side of the outer race 12. Therefore, even when the outer race 12 is fitted with the outer circumference of the shaft member 11 which is disposed in a horizontal direction at the assembling step, the rollers 13 and the resilient members 14 do not come off f om the pocket portions 21 at all.
  • the one-way clutch production method according to the present invention can reduce the number of man-hours because an outer race is produced by cold presswork of a disk-shaped blank.
  • the present invention is useful in the power machine industry.
