However, in terms of the rolling bearing retainer, ^^ is suitable for the engine to rotate at a higher speed, and the performance of the bower is improved. Compatible. The above-mentioned rolling bearing is manufactured by hand, and it is durable. However, the above-mentioned rolling shaft is used to make the inner circumference of the retainer slightly 疋. In the case of the large end, the thickness = the recessed portion has a meandering shape, and the surface contact is uneven. And the retainer is rotated by the ring material: when the inner end of the large end portion of the connecting rod, a lot of chips occur, and the chip must be pulled, and In addition to the processing cost, the above-mentioned retainer is rotated by a ring material to add a f. The concave portion has a gate shape, and the corner is smashed, and the processing is difficult, but due to the continuous shape of the U-shaped wall, the connecting rod Big end ===== , the shape of the continuous wall of the rugged wall is in the middle of February, and the rolling bearing is used to form a trapped shape. The moving method cannot make the orbital wheel into a high-precision shape. [Invention] The purpose of this month In order to solve the above-mentioned actions, and cheap, further development Please develop L to provide a rolling bearing to keep its ^, hold 1251057 shape, close _ processing speed rotation. ,,, near the hand, the zodiac b, can be correspondingly suitable for the high holder, and separately accommodated in the limb The column portion of the structure is characterized in that the rolling axis of the outer peripheral surface vi== of the retainer forms an inner peripheral recess, and the retainer=two: shape=form====moving and turning processing, etc. Adding the surface of j's curve: Vertical: The surface is formed to form a single-half straight line combined with a single-radius curved surface. Furthermore, the diameter is formed by the longitudinal section. '"Line^ length is equivalent to the rolling bearing. The bearing retainer is in the middle of the column, and the column portion is formed to prevent the inner side from falling off, and the inner holding claw is formed to prevent the inner side from falling off, and the rolling bearing is prevented from being flush with the outer peripheral surface of the holder. The outer peripheral side of the holding claw is formed to be respectively located with the inner holding claw to form a convex portion that abuts each position, and the inner concave side of the circumferential concave portion is located on the inner circumferential surface of the portion Flush. Or use the lateral section of the recess in the _ week (four) On the outer side, the column portion of the retainer is formed by a groove. The portion of the reduced portion 7 1251057 between the thick portions is formed by a portion of the reduced portion to form a meandering tube: 'including the step of holding the portion The wheel of the wheel is ί 冲 冲 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 可 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动 滚动Keeping the protruding column part 'device prevents the rolling axis from being repaired to the outer circumference size, and becomes the second and second: mouth'.

The lateral dimension of the pocket portion 5 is set to be only greater than the thickness of ί except for the size of the outer t6. Each crotch part 4 is: the diameter of the bearing 2 is smaller than the retainer! The axially outer peripheral surface of the annular portion 3; the long axially outer side surface 24' is formed outside the two portions. It is completely flat: therefore, the outer peripheral surface of the retainer 1 has a large contact area with the inner peripheral surface of the bag surface, and the opposite end of the large-end recessed portion of the connecting member of the holder 1 is in the inner side of the column portion 4 The inner circumference of the circular rolling bearing retainer retains the axial center Ο, reaching the section within the length of the section 5, forming a half ^, D. more outer 'accommodating the concave curved surface of the pocket recess 12 18 = ^ ^ half ring The shape is a half-ring inner thick portion 26, and is located at two ends 27 of the two thick joints. Both sides of the thick portion 26 and the reduced portion of the thick portion 26 1 are gradually thinned, and the side surfaces of the reduced portion are smoothed and partially reduced. In the circumferential direction, the column portion 4 is provided with cl·, 丄a 丨 rolling bearing 2 〇 outer peripheral surface When the annular portion 3 constituting the column portion 4 has a sectional shape ugly = the circumference is flush with each other, and the column portion 4 has a two-sectional shape, it is confirmed that the _' 丨 1 has a large rigidity due to the gate shape. In addition, the _ coefficient of Baobian = can be light weight and the thickness of the two ends of the column portion 4 is "two sides of the workpiece, the rolling bearing 2 ^, so the rolling bearing 2 is not only achievable - partial reduction portion 27 2 Opposite member obstruction surface 2223, slanting =, under-small, and with rolling bearing dynamic bearing retainer, its converter, in addition, the diameter of the circular diameter of the cylindrical retainer is small along the rolling axis 'Therefore, it is possible to increase the number of rolling bearings 2 groups. #=4The visibility size is relatively large, so it is suitable to use the high load capacity when necessary." As described above, the rigid 1251057 retainer 1 has the inner peripheral side at both ends of the column portion 4. A pair of inner holding claws 7 are formed on both sides of the inner surface side at the boundary portion between the two thick portions 26 and the reduced portion 27 in the vicinity of the portion. Further, on the outer peripheral side of the retainer 1, approximately one side opposite to the inner holding claw 7 is formed. The holding claws 6. The outer holding claws 6 and the inner holding claws 7 are set to protrude toward the pocket portion 5, and the holding claws 6, 7 of the adjacent column portions 4 in the circumferential direction are spaced apart from each other, which is smaller than the diameter of the rolling bearing 2. Therefore, the rolling bearing 2 When moving to the outside, it is restricted by the outer holding claw 6, and the inner side is subjected to movement. The side retaining claws 7 are restrained from falling off from the retainer. Each of the column portions 4 is formed at a central portion in the axial direction and on both sides in the circumferential direction, and a widened portion 8 partially enlarged by the pocket portion 5 is formed, and the wide portions on both sides are formed. 16 is cut to a predetermined length to form the narrow portion 17. The bag portion 5 is widened at the center to increase the capacity of the rolling bearing holder to incorporate the lubricant (oil). The rolling bearing holder forms the pocket portion 5 at the center of the shaft of the column portion 4. The widened portion 8 is excellent in lubricity when attached to the large end portion of the connecting rod. The rolling bearing retainer, particularly as shown in Fig. 3, the outer peripheral surface 9 of the retainer 1 is flush in the axial direction, and the retainer 1 is The inner circumferential surface 11 is formed in the center of the axial direction, and the inner circumferential concave portion 12 formed by the semicircular concave groove formed by the concave curved surface is formed by rolling processing. Further, as shown in FIGS. 3 and 4, by holding The inner peripheral diameter of the maximum diameter of the bottom portion 31 of the inner circumferential recess 12 of the axial center of the inner portion of the inner circumference ,, that is, the inner diameter dl of the inner circumferential concave portion 12, that is, the circle at which the bottom portion 31 of the inner circumferential concave portion 12 is respectively coupled along the circumferential direction a diameter dl of the shape 30, characterized in that it is formed to be straighter than the pitch of the rolling bearing holder The PCD is large. The concave curved surface 18 of the inner peripheral recess 12, as shown in Fig. 3, is formed in a longitudinal section (axial direction) in a curved surface 10 of a single radius R. The column portion 4 of the retainer 1 is formed inside. The claws 7 prevent the rolling bearing 2 from falling inward. The inner holding claws 7 are formed flush with the inner peripheral surface 11 of the holder 1. This rolling bearing holder forms a partially flush pocket on the outer peripheral surface 9 of the holder 1. In the column portion 4, the claw portion 6 is formed on the outer side of the column portion 4 of the retainer 1 so as to prevent the rolling bearing 2 from falling outward, and the outer holding claw 6 is flush with the outer peripheral surface 9. Further, as shown in Fig. 2 The column portion 4 is widened by a portion of the pocket portion 5 at a height of 111251057 on both sides in the circumferential direction of the axial center to form a widened portion 8, so that lubricity flows well to improve lubricity. Here, the rolling bearing holder has a concave curved surface 18 shape of the inner circumferential concave portion 12, and the rolling processing step shown in the block diagram of Fig. 5 can be excellently performed. On the other hand, the known rolling bearing holder disclosed in Patent Document 1 of the present application can be processed by a turning process in a rectangular concave groove. The rolling bearing retainer has a concave curved surface in the concave portion of the inner circumference, and forms a circular shape having a single radius R. Since there is no 崚 corner angle, the lubricating oil also flows along the concave curved surface, so that the lubricity is good. In the central region of the inner circumferential recess 12, the diameter dl of the imaginary circle 30 centering on the axial center center is, in other words, the diameter dl of the bottom portion of the inner circumferential recess 12 is formed to be the diameter of the pitch circle from the rolling bearing holder. RC.D. extends to the outside. Although the center area of the inner circumferential recessed portion 12 is deep, the use of the rolling process ensures sufficient rigidity and strength, which is advantageous for the weight reduction of the retainer 1, and the centrifugal force load of the large end portion of the engine connecting rod is reduced due to the reduction of the retainer 1. . The rolling bearing 2 is in contact with both the thick portion 26 of the column portion 4 and the both side portions of the partial reduction portion 27, and is guided on both sides to reduce the skew of the rolling bearing 2. As shown in Fig. 4, the rolling bearing retainer is used for an engine, in particular, when it is assembled at the large end portion of the connecting rod, compared with the inner peripheral gap S2 between the crank pin and the outer peripheral gap between the inner peripheral surface of the large end portion of the connecting rod. S1 is small (S2 > S1), and the outer circumference of the retainer 1 is guided by the inner peripheral surface of the connecting rod, that is, the cover. As described above, the outer peripheral surface of the retainer 1 is flush, so that the contact area between the outer peripheral surface 9 of the retainer 1 and the inner peripheral surface of the cover is increased, and the contact surface pressure is reduced, so that no lubricating oil is required. Metal contact. In particular, when the inner holding claw 7 is formed on the inner side of the retainer 1, the inner peripheral projection 21 extending toward the pocket portion 5 is formed at the same time as the rolling process (Fig. 7), and the inner peripheral projection 21 is utilized. The inner peripheral surface 11 of the retainer 1 is formed into a flush shape to form the inner holding claw 7, and therefore, the inner holding claw 7 is formed at a position flush with the inner peripheral surface 11 of the retainer 1, and is held by a conventional rolling bearing. In comparison with the device, the rolling bearing 2 does not easily come into contact with the inner holding claw 7. When the connecting rod rotates, the inner holding claw 7 does not easily contact the rolling bearing 2, and even if the engine rotates at a high speed, the retainer 1 is not easily burned, and the high performance of 12 l25l〇57 is higher than the conventional one, and the step of making the retainer is performed. Second action =; This rolling bearing retainer method, the original " tubular material, cut and cut, made: 匕 is the material of the retainer 1 material using rolling, the shape ^V step 1), ring 2 The retainer contour becomes a rolling plus 4 ^ week recessed shaped workpiece 14 along the circumference of the side 2) ° followed by 'rolling' into a boring product (step 3). =^=2 #Multiple pockets = The pillars 4' form the pocket portion 5 which prevents the rolling bearing 2 and the =:: port from forming the processed product 28 (step 4). The protrusion portion 21 is held by the dog outlet portion 21, and the projection portion (not shown) is formed on the inner circumference side of the outer side. Next, the width of the outer side of the processing is maintained to a predetermined width. The grinding process is performed, and the processing is modified, and the processing is performed. The durability is '3' and the outer peripheral grinding machine is drilled (step ^ _ pre-疋The outer circumference of the ruler, the surface treatment processing, so that the 'two:),. ^:=3 sharpener). The surface treatment of the holder 1 can be held in a state of 1 (step ^ ^ holder) through the above surface treatment Ding or Qian Yin, etc. = each bag portion 5, complete the inner circumference side, join the work insurance scroll The retainer contour in the processing is formed by the inner peripheral recess 12 forming a concave curved surface. 8. The mouth is formed in the movable workpiece 14 of the retainer 1 and the retainer contour on the surface of the retainer j is held by the gripper 7. Device: inside, part 21 'do not go to the outside and inside position, can be kept in the rolling bearing〗 〖Ying Shao 5 rotation from 13 1251057 holding the claw 7 J and other components of the cover 'handling easy. The St-bag portion 5 of the 4 is extended to make the circumferential direction: the car is protected by the bearing 2 ===, which is smaller than the diameter of the rolling bearing 2, "falling off. Also, the inner side: holding the claw = anti-rolling bearing 2 toward the retainer 1 The inner and outer movable bearing retainers are assembled in the function of the H-glazed bearing 2, and the rolling rolling bearing 2 is detached, so that the "f-jun" can be easily assembled to prevent the internal processing shown in Fig. 3 from being easy. The inner peripheral surface and the inner circumference are formed. The concave portion 12, 'on both sides in the circumferential direction of the g portion 4, the shape is formed into the inner circumferential surface U and the inner surface ^ ^ The inner side of the portion 4n is protruded. The inner holding claw 7 is formed by the method of forming the claw 7 in the above-described roll-rolling product 28, and the inner peripheral portion 21 is formed on the inner peripheral surface. The inner circumferential projection 21 is held in the a-shaped portion of the inner circumferential surface, and the inner side of the projection is held on both sides in the tight direction, and the circumference of the column portion 4 is flush with the inner circumferential surface 11 . The shell claws 7 are formed in contact with the movable bearing 2. The gap of the specific hole 2 is large, and it is difficult to be on the side of the roller diameter. The body 3 is located on the inner side of the fourth figure and the claw 7 is slightly inward. The third example is shown in Fig. 3. The second rolling groove of the second embodiment of the concave bearing 12 has a concave curved surface. The two-section is easy to enter, and the inner surface is half-tested by the curved surface 19, but according to the 8th of the concave radius of the radius R, the longitudinal section is viewed. The concave curved surface shape of the two single inner circumferential recesses 12 is formed in the composite semi-annular concave shape, that is, the same as in the plane joint application, 'through the axial center of the retainer 1 (10) 1251057, the ratio is ==== two ^.
