３２２１９５で開示されている方法である。For producing cages for ζ roller bearings from sheet metal, methods such as those described above are known, as well as the method of first stamping the rolling elements Ikerato into flat sheet metal strips. For the former method, for example, U33365775 and DI-0M7
This is the method disclosed in No. 322195.

Ｉケラトの寸法は不正確なものとなる。In the method according to U33365775, the weld seam is
Since the rolling elements are within the range of 0), the number of rolling elements is 4) 0
The narrow side rings K formed in 1i11i therefore require very short weld seams. However, with this method,
Since the rolling element I kerato is stamped at a depth of 110 mK at the end of the ring, the pitch and the dimensions of the rolling element I kerat formed in the region of the weld seam are inaccurate.

、し良がって側輪の幅にしか及ばない。DI-0M7B! The retainer according to 2195 is made in a similar manner. The weld seam lies within the range of the rolling elements I and thus extends only to the width of the side ring.

えるので、手間と材料費が高くなる。Among them, it is also known that the ends of a band wound in a ring shape are welded and then the rolling element I cerato is punched out (083699
793), the sequence of working steps offers some advantages in terms of the pitch of the rolling element pockets and the accuracy of the angle of inclination of the rounding web of the plate rolling element during the dimensions, but when the punching tool punches out the weld seam. A problem arises. Welded seams are usually made of thin sheet materials (thin sheets), which are usually very hard, so the punching tools will be damaged quickly. For this reason, there is a method 4 in which the punching process is not influenced by the weld seam and is arranged in such a way that it is arranged between two rolling elements, ie on one web 01. However, in this case, the welded seam spans the entire width of the cage, which increases labor and material costs.

れ喪ころがり保持器を提供するものである。The problem of this invention is to create a method in which the welded seam is short, the punching tool does not touch the welded seam, and the remainder of the welded seam does not protrude into the rolling element I, and the method can be manufactured by this method to maintain rolling performance. It provides equipment.

、自由端に開放し九切欠部が加工され。This task involves cutting the thin strip 10 at the same time as the cutting process 11, and cutting the thin strip 10 at both ends.
Within the width dimension range of the rolling element I kerato to be processed, nine open notches are processed at the free end.

堆夛のさいに同時に両自由端で加工し。The solution is that in the stamping process of the t+ rolling element I-ket, one of these rolling element I kerats is machined in the region of the seam point. Hereinafter, the width of the rolling element I kerat, the hole, and the notch refers to the dimension in the circumferential direction of the cage, and the length thereof refers to the dimension in the width direction of the cage.・Notch properties: Advantageously, the thin strip can be cut at both free ends at the same time during cutting and stacking.

ｔ）。For example, the window hole formed in IIK can be half the size of a rectangle. The dimension in the direction of the ring width is chosen to be just one wide strip to ensure sufficient strength for the weld 11. In any case, the rolling elements 1ei to be punched out along these dimension lines are such that the necessary punching tool does not touch the weld m, and furthermore, the weld seam can touch the rolling elements 1! (length of I-nit) must be correspondingly large. The width dimension of the notch in the circumferential direction of the cage is such that the edge thereof is punched out and is within the width of the four round plate moving bodies.

よって打落されるの社わずかな部分にすぎない。It should be chosen small enough to be punched out during this punching process. The sheet metal strip with a cutout at its free end is then bent into a ring, and the narrow free ends are joined and welded at their end faces. In the next step, the bent nine rings are punched with rolling elements I kerato at appropriate intervals. The punching is then started, for example, in the area of the weld seam, and the ring is positioned circumferentially in such a way that the window hole is within the width of the first rolling element pocket. ζThus, even though the guide surfaces of the rolling elements are formed in the region of the weld-eye as well in the rolling element pocket punching process, and the weld seam is effectively short and lies within the range of the rolling element pockets, this method Benefits are maintained. The guide surfaces of the end faces of the rolling elements in the circumferential direction of the cage are also formed by punching K of the rolling elements I kerato. In the area of the weld seam, only a small portion is knocked out by the machining of the window hole.

にとって有利に対称の状況が生じる。The elongated notch, which is arranged in the area of the weld seam and is created by the window hole and remains in the hole of the punching of the rolling element pocket, is in the middle of the rolling element Iket, so that it is advantageously symmetrical for the rolling element end IiO guide. The situation arises.

。In another variant, two circular holes are provided which are aligned in the width direction of the cage. This construction is advantageous when cutting thin strips from the strip, as the 0-circular holes can be punched out with easy-to-make tools! It is arranged in the width direction of the sheet metal strip so that it projects approximately half way above the edge of the rolling element pocket which is subsequently punched out. During cutting, the cutting edge passes through the center of the circular hole. After welding and welding, two circular holes are produced, which are welded only in the region of the side wheels.After punching out the rolling element pockets, the desired semicircular O-notch remains in the area of the weld seam.

At the same time, notches 2 are machined on both ends, so that edges 3 of a corresponding width O are left for later joining. The size of the notch is explained in the ninth KiI to make it easier to understand.
As shown in Figure bK, the thin plate strip 1 is attached to the ring 4.
As a result, a seam 6 is created at the free end 50. At this seam point 6, the free ends 5 of the sheet metal strips 1 abut with their edges 3, as shown in FIG. As a result, a window hole 7 is created. The free end 5 of the thin plate strip l is al1

から離れて位置すればよい。In the final bale process, as shown in FIG. 1, a ring 4 with rolling element pockets 8 is punched out. These O rolling element pockets 8 are arranged so that one of them is approximately symmetrical with respect to the center line of the existing window hole 7. Since the window hole 7 is longer than the length of the rolling element pocket 8 in the direction of the ring width,
The punching tool is used to punch out the weld seam 9 which is located a little distance away.Since the rolling element pocket 8 is relatively wider than the elongated window hole 7 in one direction of the ring 40jlll, it is necessary to punch out the weld seam 9 which is located at a distance. The rolling element pockets 8 shown are for cylindrical rollers, resulting in a round plate 4-piece pocket 8, which in terms of dimensions complies with the tolerances of the punching tool. The guide surface 10a of the roller end face of the side wheel and the long silk notch 1e where the window hole 7 is also left.
Since it is only slightly reduced by C, it has almost no effect on the guiding conditions of the end face of the cylindrical roller.The residual paper of the protruding weld seam does not touch the end face of the cylindrical roller.
Since there is no need to remove 70 rounds, there is no need for reworking at all, and the notch and window hole 7 can be made relatively longer by KiI. Therefore, the weld seam 9 is a cylindrical ζrowir*
It should be located far away from

部分１３が落下する。Figure 2 shows a cage for spherical rollers. A semicircular notch 11 is formed using a simple round punching tool when cutting the thin plate scrap l, and this notch is used to join and weld the free end 5 of the ring 4 as shown in the figure. O11 becomes a circular large 12. Since the rolling element pocket 8 is punched out as shown by the broken line, a semicircular notch 9 remains in the center of the ring, and the weld *a is moved away from the side of the ring by the cutout K. As a result of the punching, the inner, unconnected sheet metal parts 13 fall off.
