For example, endless metal belts used in continuously variable transmissions for automobiles or general power transmission applications generally transmit power through pulleys 1, 1, as schematically shown in FIG. Therefore, during use, the endless metal belt 2 is subjected to tensile stress on the outside at the position of the pulleys 1, 1, and compressive stress on the inside, and is subjected to severe stress conditions such as repeated bending stress. used in

十分であつた。 For this reason, attempts have been made to apply tensile stress to the inner circumferential side of the metal belt or compressive stress to the outer circumferential side in advance, as seen in Japanese Patent Application Laid-open No. 53-42172, but this approach reduces the fatigue life. This was not enough to improve the situation.

The gist of the present invention is to provide a pair of tension rollers that wrap around an endless metal belt and apply tension while running the metal belt; a first rolling roller that presses the metal belt from the inner circumferential side toward the outer side in contact with the surface; and a first rolling roller that is provided on the outer circumferential side of the metal belt opposite to the first rolling roller. A second rolling roller having an outer diameter smaller than that of the roller and rolling the metal belt between the first rolling roller and the first rolling roller is provided.

とができる。 According to the above configuration, it is possible to apply stress to the metal belt by the pair of tension rollers, and also to apply bending to the belt by the first rolling roller. The belt is rolled by one rolling roller and a second rolling roller having a smaller diameter and paired therewith. Since the first roller has a larger diameter than the second roller, deformation of the inner peripheral side of the metal belt in contact with the first roller is restrained during rolling. On the other hand, the second
Since the rolling roller has a small diameter, the outer circumferential side of the metal belt is constrained relatively little by the second rolling roller. Therefore, during rolling, the outer circumferential side of the metal belt is expanded more than the inner circumferential side. As a result, it is possible to generate compressive residual stress on the outer circumference of the belt and tensile residual stress on the inner circumference of the belt, greatly improving the durability of this type of endless metal belt that is subject to repeated bending stress. can be improved.

An embodiment of the present invention will be described below with reference to FIG. In the figure, reference numerals 10 and 11 indicate tension rollers. These tension rollers 1
At least one of 0 and 11 is rotatably driven by a drive mechanism (not shown), and an endless metal belt 2 is wound around the belt 2 to cause the belt 2 to run endlessly. Furthermore, the tension rollers 10 and 11 are configured so that the distance between them can be changed and tension can be applied to the metal belt 2. For example, this metal belt 2 has a thickness of
It is preformed into an endless band shape from stainless steel or the like with a thickness of about 0.1 mm to 0.3 mm. However, the material and thickness do not matter.

られる。 A first rolling roller 12 is provided between the tension rollers 10 and 11. The first rolling roller 12 is in contact with the inner peripheral surface of the metal belt 2 and presses the belt 2 from the inner peripheral side toward the outside. Further, a second rolling roller is disposed on the outer peripheral side of the metal belt 2, facing the first rolling roller 12.
rolling rollers 13 are arranged. The second rolling roller 13 has a smaller outer diameter than the first rolling roller 12, and is adapted to roll the metal belt 2 between it and the first rolling roller 12. Further, in order to support the second rolling roller 13, a back up roller 14 is provided as necessary.

きる。 In the apparatus of the embodiment having the above configuration, rolling is performed by rolling rollers 12 and 13 while tension is applied to the metal belt 2. Thus, during this rolling, a part of the metal belt 2 is wrapped around the first rolling roller 12 located on the inner peripheral side of the metal belt 2, and this first rolling roller 12 is wrapped around the second rolling roller 12. Since the metal belt 2 has a larger diameter than the rolling roller 13, deformation of the inner peripheral side of the metal belt 2 in contact with the first rolling roller 12 is restrained during rolling. On the other hand, since the second rolling roller 13 has a small diameter, the outer peripheral side of the metal belt 2 is relatively restrained from being deformed during rolling. Therefore, during rolling, the outer circumferential side of the metal belt 2 is expanded more than the inner circumferential side. As a result, a compressive residual stress is applied to the outer circumferential side and a tensile residual stress is applied to the inner circumferential side, so that the endless metal belt 2 exhibits excellent durability. For example, when transmitting power via pulleys 1 and 1 as illustrated in FIG.
A strong tensile stress acts on the outside at the position of the pulleys 1, 1, and a compressive stress acts on the inside, but as mentioned above, the metal belt 2 is compressed in advance on the outer circumference side and then on the inner circumference side. Since tensile residual stress is applied, excellent fatigue life can be obtained even under severe stress conditions where repeated bending stress acts.

As described above, according to the present invention, it is possible to apply stress to the metal belt by the pair of tension rollers, and further to apply bending stress to the belt by the first rolling roller. Moreover, since the belt is rolled between this first rolling roller and a small-diameter second rolling roller placed on the outer circumferential side of the belt, it is effective in improving the durability of the endless metal belt. It is extremely effective in improving the fatigue life of endless metal belts.
