Problems solved by technology

[0007] However, it has the following problems: the metal element constituting the metal strip is a part that requires high dimensional accuracy, but, for example, when heat treatment is performed in the manufacturing process, slight deformation (bending, warping, deflection, etc.) may occur in the metal element. bending), if such a deformed metal element is wrongly assembled to the metal belt, the contact surface between the metal element and the pulley will slide during operation, so it will cause abnormal wear of the pulley, or cause transmission due to heat generation. Reasons for inefficiency

no. 1 Embodiment approach

[0051] First, according to Figure 1 to Figure 5 A first embodiment of the present invention will be described.

[0052] In addition, the definitions of the radial direction, width direction, and front-rear direction of metal elements used in this specification are as follows figure 1 shown. The radial direction is defined as the radial direction of the pulley in contact with the metal element, the side closer to the axis of the pulley is the radial inner side, and the side farther from the axis of the pulley is the radial outer side. In addition, the width direction is defined as the direction along the shaft of the pulley which abuts on the metal member, and the front-rear direction is defined as the direction along the moving direction of the metal member.

[0053] Such as figure 1 As shown, a metal belt 11 for a belt-type continuously variable transmission supports a plurality of metal elements 13... in a pair of left and right metal ring assemblies 12, 12. Each metal r...

no. 2 Embodiment approach

[0063] Next, according to Figure 6 and Figure 7 A second embodiment of the present invention will be described.

[0064] Such as figure 2 As shown, in the first embodiment, the light leaked from the gap between the metal elements 13... is visually observed, but as Figure 6 As shown, in the second embodiment, the light leaked from the gap between the metal elements 13... is observed by imaging with an imaging means 35 such as a CCD camera, for example.

[0065] The dummy pulley 32 of the second embodiment has the same circular shape as an actual pulley, and the dummy pulley 32 is rotatably supported by a rotating shaft 37 vertically fixed to the stay 31 . A light source 33 is fixed to the rotation shaft 37 , and an imaging member 35 is arranged on the radially outer side of the dummy wheel 32 so as to point to the light source 33 . Dummy wheel 32 is rotated by a predetermined angle (for example, 10°) each time metal element row 13 ′ is wound around V-shaped groove 32 b ...

no. 3 Embodiment approach

[0070] Next, according to Figure 8 A third embodiment of the present invention will be described.

[0071] In the third embodiment, two dummy wheels 32 , 32 are arranged adjacent to each other on a rotating shaft 37 , and metal element rows 13 ′, 13 ′ are wound around the two dummy wheels 32 , 32 , respectively, for inspection. In addition, the rotation shaft 37 of the dummy wheel 32 is arranged vertically, and the row 13' of the metal elements 13 moves in the horizontal plane. At this time, the two metal element rows 13', 13' are photographed by one imaging member 35, thus the two metal element rows 13', 13' can be inspected at the same time, and the work efficiency is improved. The number of imaging means 35 is reduced to save equipment costs.

[0072] If the method of finding the deformed metal element 13 according to the area of ​​each light image in the image captured by the imaging member 35 is adopted, then it can be known that the deformed metal element 13 is one of...

Abstract

A metal element deformation state detection device is provided in which since a plurality of the metal elements are in line contact with each other via a rocking edge and are aligned in an arc shape to form a metal element row, a light source is disposed on the radially inner side or the radially outer side of the arc of the metal element row, and a deformation state of the metal element is detected by observing passed-through light that has been emitted from the light source and has passed through a gap between adjacent metal elements, slight deformation in the metal element can reliably be detected.

Description

technical field [0001] The present invention relates to a deformation state detecting device of a metal element for detecting the deformation state of a metal element constituting a metal belt used in a belt type continuously variable transmission. Background technique [0002] The following Patent Document 1 discloses a structure in which a metal belt used for a belt-type continuously variable The metal belt of the transmission is supported by a pair of metal ring assemblies (rings) with a plurality of metal elements, and the direction of assembling the metal belt is determined according to the direction of the slope (locking edge) of the metal element determined from the image, or according to The type of metal strip is determined by the width of the metal element itself or the width of the ring groove of the metal element.
