いる。 These thrust needle roller bearings are used in combinations that suit the purpose. However, it is inconvenient to assemble needle rollers with cages and raceway rings when assembling them into machines, etc., and a bearing in which raceway rings, rollers, and cages are assembled in a non-separable manner is desired. There is.

がある。 In another structure, as shown in FIG. 2, a cylindrical portion 6 is formed by bending the outer circumferential edge of the bearing ring 5 outward, and a retainer 7 and a cylindrical portion 6 are formed on the bearing ring 5. After the rollers 8 are assembled, the ends 6a of the cylindrical portion 6 are bent inward and locked to the cage 7 to prevent them from falling off, and the raceway ring 5, cage 7, and rollers 8 are non-separable. The end portion 6a of the cylindrical portion 6 is bent in advance, and the entire cylindrical portion 6 is pushed outward to the extent that the retainer 7 can be inserted.After inserting the rollers 8 and the retainer 7, the cylindrical portion is There is one in which the two are pressed inward and integrated.

いる。 In this way, in the conventional non-separable thrust needle roller bearing, after the retainer and rollers are assembled to the bearing ring, the other end 4b of the side ring 4 or the end 6a of the cylindrical part 6 of the bearing ring 5 is deformed. This is how they are combined. Therefore, in order to facilitate caulking, in the former case, the side ring 4 is not hardened, and in the latter case, when the bearing ring 5 is carburized and hardened, the cylindrical part 6 is treated to prevent carburization, or after carburizing and hardening. It is also tempered.

なかつた。 Therefore, in the former case, the number of parts is large, the number of assembly steps is increased, and the side wheels 4 and retainer 2 come into contact with each other, causing wear of the side wheels 4, and the bearing function cannot be fully demonstrated. Also in the latter case, the cylindrical portion 6 of the bearing ring 5
Various treatments had to be carried out to prevent the bearing from hardening, which increased the number of manufacturing steps and caused the cylindrical part 6 to come into contact with the retainer 7 and wear out, making it impossible to fully demonstrate the bearing function.

A ring having a ring-shaped bearing ring formed by bending the thin-walled part toward the roller side starting from the thin-walled base part and forming an annular locking flange extending all around the circumference, and a ring-shaped bearing ring that accommodates and holds a plurality of rollers at equidistant positions on the circumferential surface thereof. a cylindrical flange, one of which has a pocket hole that has a pocket hole, and whose outer and inner circumferential edges are bent in the same direction in the same direction to form a cylindrical flange that slightly interferes with the locking flange over the entire circumference; and a retainer in which the bent base of one cylindrical flange facing the locking flange is formed into an arc shape and an edge portion is formed at the opposite end, and the retainer is fitted into the cylindrical portion of the bearing ring. Since the edge of the cylindrical flange of the retainer and the locking flange are engaged and integrated in a non-separable manner, when the retainer is fitted into the raceway, the bent base of the retainer's cylindrical flange is The locking flange of the raceway ring is gradually elastically deformed by the arcuate portion and can be easily fitted.

も容易に適用できる。 This is the ring-shaped locking flange of the raceway.
The thin wall allows the locking flange to be easily elastically deformed, and the arcuate portion of the retainer serves as a guide surface that gradually causes the locking flange to undergo elastic deformation. This is due to its action and effect. Of course, since the locking flange is annular, deterioration in the strength of the cylindrical portion can be prevented, and it can also be easily applied to those with a short cylindrical portion (small diameter needle bearings).

There is no need for tempering after quenching, and manufacturing costs can be reduced. In addition, in making the bearing ring and retainer non-separable, a part of the bearing ring is used instead of a separate member, so the number of parts is small, and the bearing ring By incorporating the retainer using a method that utilizes elastic deformation, it can be assembled in a one-touch manner, eliminating the need for caulking work after assembly, and thus improving the workability of assembly.

スラスト針状ころ軸受。 A cylindrical portion is formed by bending either the outer or inner periphery of the rolling surface of the annular roller into an L-shape, and the cylindrical portion is made thinner than the cylindrical portion from the middle to the tip. The bearing ring has a thin-walled base as a starting point and the thin-walled portion is bent toward the roller side to form an annular locking flange extending all around the circumference, and the ring is shaped like a ring and accommodates and holds a plurality of rollers at equidistant positions on its circumferential surface. a cylindrical flange having a pocket hole, whose outer and inner circumferential edges are bent in the same direction into an L-shape, one of which slightly interferes with the locking flange over the entire circumference; A retainer is provided, the bent base of one of the cylindrical flanges facing the locking flange is formed into an arc shape, and an edge portion is formed at the opposite end, and the retainer is fitted into the cylindrical portion of the bearing ring. A thrust needle roller bearing characterized in that an edge portion of a cylindrical flange and a locking flange are locked and integrated in a non-separable manner.
