In general, an annular clutch facing has a plurality of radial grooves 2 formed on the surface by connecting the inner and outer circumferential parts of the clutch facing 1, as shown in Fig. 4, and rivet holes are formed between these grooves. 9 and relief holes 3 are alternately bored. As shown in FIG. 6, the rivet hole 9 consists of a large-diameter hole 6 drilled from the surface of the clutch facing 1 halfway in the thickness direction, and a small-diameter hole 7 penetrating from its tip to the back surface of the facing 1. Then, the head of the rivet is locked at the boundary between the large diameter hole 6 and the small diameter hole 7, and the body of the rivet is passed through the small diameter hole 7 and loosely inserted into the cushion plate on the back side of the clutch facing (not shown). This secures the clutch facing to the plate. As shown in Fig. 5, two rivet holes 9, 9' and two relief holes 3, 3' are bored in the radial direction between the radial grooves 2 of the clutch facing, thereby increasing the strength of the rivet joint. A two-hole clutch facing 8 with an increased diameter is also commonly used.
ところが上記リベツト穴の大径穴６は通常摩擦
面に穿設するため第６図に示すように切削加工に
よる大径穴６の深さL2が大きく、クラツチ作動
時に該穴６の周囲に割れが発生し易く問題であつ
た。 However, since the large diameter hole 6 of the rivet hole is usually drilled on a friction surface, the depth L2 of the large diameter hole 6 is large due to the cutting process, as shown in Fig. 6, and cracks may occur around the hole 6 when the clutch is operated. This was a problem because it was easy to occur.

With this in mind, after various studies, we have developed a clutch facing with high strength around the rivet hole, which is an annular clutch facing with many radial grooves formed on the surface connecting the inner and outer peripheries. In the clutch facing, an expanded portion that expands to form a smooth convex shape on both sides in the circumferential direction is provided at one or more locations of every other groove in the circumferential direction, and rivet holes are drilled in the expanded portion. It is characterized by the fact that

Providing a wide expanded part in the groove and drilling a rivet hole in the expanded part in this way is different from the conventional method of creating rivet holes by cutting, and the expanded part of the groove that is not machined is created during the manufacturing process of the clutch facing. This is because the hard parts called black scales that are formed remain, and by drilling rivet holes in areas with a lot of black scales, the strength around the rivet holes is improved. Since the depth is reduced, the strength can also be improved from this point of view.
本考案を一実施例にて説明する。 The present invention will be explained using an example.

ーシング１の反対面に貫通している。Embodiment (1) As shown in Fig. 1, a radial groove 2 is formed on the surface of an annular clutch facing 1 to connect the inner circumference and the outer circumference.
, a relief hole 3 is formed between the grooves 2, and a rivet groove 5 is formed in which the central part is provided with an expanded part 4 that expands convexly on both sides in the circumferential direction. A rivet hole 6 was bored in the expanded portion 4. As shown in FIG. 2, the rivet hole portion has the same depth as the rivet groove 5 provided on the surface of the clutch facing 1 and the expanded portion 4, and the inner wall surface of the expanded portion 4 has black crust ( The center part of the clutch facing 1 is covered with a large diameter hole 6 for a rivet, and a small diameter hole 7 penetrates from the tip of the large diameter hole 6 to the opposite surface of the clutch facing 1. are doing.

優れている。されに第２図に示すように大径穴の
加工深さL1は従来の第６図に示すようなL2に比
べて小さいため、大径穴が表面割れに及ぼす影響
は極めて小さい。 In this way, the large-diameter rivet hole is formed in the expanded part of the rivet groove where the black crust remains, so when the clutch is activated, the frictional force acts on the black crust, so cutting is not required as in the conventional method. Unlike the parts that are coated and have no black skin, they have high strength and are resistant to cracking. Furthermore, as shown in FIG. 2, the machining depth L 1 of the large-diameter hole is smaller than the conventional L 2 shown in FIG. 6, so the effect of the large-diameter hole on surface cracking is extremely small.
