Abstract

PURPOSE:To provide a residual bending stress to a metallic belt and to lengthen its service life by press-rotating a metallic belt stretched around a guide roll with the aid of a small diametral pressing roll in manufacturing a metallic belt. CONSTITUTION:A metallic belt 1 is press-rotated by a pressing roll 3 which is smaller in diameter than a guide roll 2 by bringing the inner surface of belt 1 into contact with the guide roll 2. When a bending stress of about one-half of the maximum bending stress produced during operation is provided to the belt 1, a bending stress acting on the belt 1 becomes about one half of the maximum stress, and the service life of the belt 1 is remarkably improved.

σ、＝Ｅ、石でボされる。Detailed Description of the Invention (Industrial Application Field) The present invention relates to a method for imparting residual bending stress to a metal belt. The lifespan of metal belts such as torque transmission belts for transmissions depends on the amount of residual bending stress imparted to them. is said to be optimally set to about j times the stress. Here, the residual bending stress is defined as the residual bending stress, as shown in Fig. 1.
When the belt is cut, the cut part is deformed inward in a small arc shape.If the diameter of the belt is t, the thickness is t, and Young's modulus is E, then Bending stress σ, = E, broken by stone.

Therefore, in order to extend the life of the belt 1, it is a good idea to set the plastic deformation applied to the outer surface of the belt 1 to be a predetermined amount larger than the plastic deformation applied to the inner surface.

The purpose of this invention is to bring the inner side of the gold II belt into contact with the guide roller that guides the metal belt, and This method is characterized in that the outer surface of the metal belt is pressed by a guide roller and a pressure roller with a small diameter, and a metal belt h=4 is rolled by both rollers to impart residual bending stress. As a result, large plastic deformation is applied to the outer surface ill of the metal belt as well as to the inner l1L7 side. By applying a change to 41", the magnitude of the residual bending stress on the metal belt can be easily set to a desired size, thereby improving the life of the belt.

Next, when rolling forming the endless metal belt 1 while pressing the outer surface of the endless metal belt 1 with the suppression roller 3, since the suppression roller 3 has a smaller diameter than the guide roller 2, the pressure roller 3 The magnitude of the plastic deformation that the outer surface of the endless metal belt 1 undergoes is greater than the plastic deformation that the inner surface of the endless metal belt 1 receives due to the guide roller 2, and residual bending stress is imparted to the endless metal belt 1.
