- the tongue piece 20 ⁇ see FIG. 2 (B) ⁇ is not provided on the inner peripheral edge of each of the through holes 18b, 18b formed in the intermediate material 29b.
- a portion of the second intermediate material 29b radially inward of the chain line ⁇ ⁇ is plastically deformed into a conical cylindrical shape by the press machine shown in FIGS.
- the large-diameter flange 8a is then removed by pressing.
- a fourth intermediate material 38 as shown in FIG. 7D is formed.
- the inner peripheral edges of the pockets 10a, 10a formed in the main portion 7 constituting the fourth intermediate material 38 are subjected to face pressing or the like, so that these pockets 10a, 10a are formed. Adjust the shape and dimensions of a to complete the above cage 4a.
- FIG. 8 to 10 show a fifth embodiment of the present invention.
- the retainer 4b of the fifth embodiment first, the same as in the first embodiment shown in FIG. 2, the second embodiment shown in FIG. 5, and the third embodiment shown in FIG.
- a conical cylindrical main portion 7, a plurality of pockets 10 and 10, and a large-diameter side flange portion 8 are formed.
- each of the band-shaped portions 30 provided at the small-diameter end of the main portion 7 is compressed in the generatrix direction (or axial direction) of the main portion 7 to be plastically deformed.
- the strips 30 & (two T7 + ⁇ T1 + ⁇ T2) of the strips 30a, 30 &
- the thickness of each of the other parts of the main part 7 is larger than the thickness T7 (T30a> T7).
- the dimension ⁇ ⁇ 1 of the band portion 30 a is the cross-sectional height of the cage 4 b to the outer diameter side due to the plastic deformation of the band portion 30 before compression.
- the dimension T 2 indicates the amount of increase in the section height toward the inner diameter side.
- the inner surfaces of the strip portions 30a and 30a formed as described above are each a single plane. Has become.
- the plate thickness T30a of each of the strip portions 30a and 30a is larger than the plate thickness T7 of the other portions of the main portion 7. (T30a> T7). Therefore, the rigidity of each of the band portions 30a and 30a can be sufficiently secured without increasing the dimensions of each of the band portions 30a and 30a in the generatrix direction (or the axial direction). In addition, the area of the inner surface of each of the strip portions 30a, 30a can be increased. For this reason, the end faces of the rollers 3 and 3 should be guided over a wide area during use by the inner surfaces of the strips 30a and 30a, and the posture of the rollers 3 and 3 should be stabilized. Can be.
- each of the strip portions 30a, 30a is used as a guide surface for inserting each of the rollers 3, 3 into each of the pockets 10, 10. In this case, the import work of these rollers 3 and 3 can be easily performed.
- the respective pockets 10 and 10a are formed along with the formation of the conical cylindrical main portion 7.
- the peripheral edge of each of the pockets 10 and 10a was subjected to surface pressing ⁇ the work shown in Fig. 13 (G) ⁇ (H) was performed ⁇ .
- the surface pressing process is performed by previously performing a peripheral portion of each of the through holes 18a and 18b before forming the pockets 10 and 10a.
- the pockets 10 and 10a can be formed into desired shapes and sizes at the same time as the pockets 10 and 10a are formed.
- the surface pressing process is performed on the conical cylindrical main portion 7 formed above.
- the above-mentioned through holes 18a, 18b formed in the ring-shaped second intermediate material 29, 29a, 29b are less than the case of applying to the peripheral portion of each pocket 10, 10a.
- the method for manufacturing a roller bearing cage according to the present invention is characterized in that the cylindrical main portion (in the case of the invention according to claim 1, further includes an outwardly bent radially outward direction from one axial end edge of the main portion).
- Roller bearing cages with flange-shaped flanges regardless of the type of roller bearings that incorporate this roller bearing cage (self-aligning roller bearings, cylindrical roller bearings, tapered roller bearings, etc.). , Can be implemented.
- the present invention relates to a roller bearing that uses a roller as a rolling element and is applied to a rotation supporting portion constituting various types of mechanical devices.
- a roller bearing retainer that holds a plurality of rollers so as to freely roll, and a roller bearing retainer. It can be used for the production method of the container.
