Abstract

(57) [Abstract] [Name of device] Holding plate for one-way clutch [Purpose] To obtain a holding plate that prevents backlash in the circumferential, radial, and axial directions of the outer ring in a one-way clutch, and prevents noise from being generated. . [Structure] A claw portion 62 that contacts the inner peripheral surface of the housing is formed on the outer periphery of the pressing plate 60.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a holding plate for a one-way clutch.

[0002]

[Prior art]

 One-way clutches are widely used as components such as torque transmission and backstops in drive devices of automobiles and the like.

In order to understand the present invention, FIG. 6 is a side view showing an example of a one-way clutch partially broken away, and FIG. 7 is a sectional view taken along line XX of FIG. Is an inner ring, 30 is a housing, 12 is a spline protrusion of the outer ring 10, and 32 is a spline groove of the housing 30. Reference numeral 14 is a cam surface on the inner circumference of the outer ring, 50 is a roller, 70 is a spring, and 80 is a spring mounting plate. When the inner ring 20 rotates in the direction of arrow R _{1 in} FIG. 6, the inner ring idles, and when it rotates in the direction of arrow R _{2, a} locking action is performed and the inner ring 20 and the outer ring 10 rotate. (The one-wake latch is a well-known technique, and thus detailed description thereof is omitted.)

[0004]

【Problems to be solved】

Since the housing 30 is a cast product, it is difficult to finish it to a precise dimension, and the gaps a ₁ , a between the side surfaces A ₁ , B ₁ of the spline groove 32 and the side surfaces A ₂ , B ₂ of the spline projection 12 are difficult. ₂ is generated, and a gap c is formed between the housing 30 and the outer ring 10 in the radial direction.

As shown in FIG. 6, play is generated in the circumferential direction indicated by arrow E due to the gaps a ₁ and a ₂ and in the radial direction indicated by arrow F due to the gap c. In addition, as shown in FIG. 7, backlash also occurs in the axial direction indicated by arrow G, and eventually backlash in the three directions of arrows E, F, and G occurs, which causes noise during operation.

There is a problem that the number of parts increases if it is attempted to suppress the generation of noise due to these backlashes. In particular, it was difficult to suppress the play in the F direction in FIG.

[0007]

[Means for Solving the Problems]

 According to this invention, in order to eliminate the above-mentioned drawbacks, a holding plate for a one-way clutch is provided, in which an outer diameter side of the holding plate is provided with a claw which comes into contact with the housing, and the frictional force thereof eliminates the play in the three directions. Is what I got.

【Example】

 FIG. 1 is a side view of a one-way clutch to which the present invention is applied, FIG. 2 is an enlarged view of a main part of a holding plate, and FIGS. 3 to 5 are explanatory views of the application state of the holding plate. It is a one-way clutch portion that is interposed between the inner ring 20 and the inner ring 20 of the outer ring 10 and has the mechanism shown in FIG. A pressing plate 60 has a bent portion 61, a claw portion 62 that comes into contact with the housing 30, and a bent portion 63 on the outer peripheral edge.

FIG. 3 shows an example in which the pressing plate of the present invention is used. The outer ring 10 is formed with shoulder portions 11 on both sides, and when the pressing plate 60 is applied, the bent portion 61 is fitted and the pressing plate 60 is referred to as the outer ring 10. It is fixed to the outside of the clutch portion 90.

The bent portion 63 at the tip of the claw portion 62 is interposed between the gaps c shown in FIG. 6 and is in contact with the housing 30.

As described above, the claw portion 62 and the bent portion 63 formed on the outer periphery of the holding plate 60 fixed to the outer ring 10 are in contact with the housing 30, so that the friction causes the circumferential direction and radius of the outer ring described above. Directional and axial play is prevented and noise is prevented.

FIG. 4 shows another example, in which the bent portion 63 has a corrugated shape facing downward and is in contact with the housing 30.

FIG. 5 shows still another example, in which the bent portion 63 does not extend above the outer ring 10 and is formed so as to be interposed between the housing 30 and the outer ring 10. As a result, a restraining force acts between the outer ring 10 and the housing 30.

As can be seen from FIGS. 3 to 5, of the holding plates on both sides of the outer ring 10, the one of the present invention is one side.

[0015]

【effect】

 The one-way clutch retainer plate of the present invention has the above-mentioned structure, and prevents the play of the outer ring in the circumferential direction, the radial direction, and the axial direction in three directions without increasing the number of parts with a simple structure. It was possible to prevent the occurrence of. Further, this holding plate can be easily manufactured by press working, and the mounting space is not increased.
