Description
【発明の詳細な説明】 〈産業上の利用分野〉 本発明は、自動車等の車輌用ディスクホイールの半径方
向の振れの測定装置に関する。DETAILED DESCRIPTION OF THE INVENTION <Field of Industrial Application> The present invention relates to an apparatus for measuring a radial runout of a disk wheel for a vehicle such as an automobile.
〈従来の技術〉 車輌用ディスクホイールは、その回転中心に対するビー
ド座部分の半径方向の振れを所定の値内に収める必要が
あって、全ての製品に対してこのチェックが行われてい
る。<Prior Art> For a vehicle disk wheel, it is necessary to keep the radial deflection of the bead seat portion with respect to its rotation center within a predetermined value, and this check is performed for all products.

ビード座は通常、回転軸に対して平行な円筒面を形成し

とθなる角度である場合には、ディスクホイールの軸方
向の振れをΔＬとしたとき、 ΔＥ＝ΔＬ・tan θ ……（１） なる誤差が、半径方向振れ測定値に含まれることにな
る。Conventionally, the shake is measured by attaching a disk wheel to a rotating shaft, rotating the disk wheel, applying a contact to the bead seat, and detecting the amount of movement in the radial direction. If the position of the contact is fixed in the direction of the rotation axis during this measurement, and if there is axial runout on the disc wheel,
The bead seat normally does not form a cylindrical surface parallel to the rotation axis but a conical surface. Therefore, if its generatrix is an angle of θ with the rotation axis, the axial direction of the disc wheel Assuming that the runout of ΔL is ΔL, an error of ΔE = ΔL · tan θ (1) is included in the radial runout measurement value.
以上の現象に対処する為に、従来、特公昭50−35282号

なわち半径方向の振れの測定位置を、フランジ面から常
に一定の距離を保った位置となるように規制していた。In order to deal with the above-mentioned phenomenon, conventionally, as shown in Japanese Patent Publication No. 50-35282, a bead seat of a disk wheel and an inwardly facing surface of a flange adjacent to the bead seat (hereinafter referred to as a flange surface), Use a contact formed by rollers that come into contact with each other at the same time so that the contact position of the contact with the bead seat, that is, the measurement position of the radial runout, is a position that always maintains a constant distance from the flange surface. Was regulated.

ある。<Problems to be Solved by the Invention> By the way, in the conventional device based on the above Japanese Patent Publication No. 50-35282, it is necessary to simultaneously press the contactor against the bead seat and the flange surface, and There is a considerable number of mechanically movable members between it and a sensor such as a differential transformer for detecting the amount of movement, and the measured value includes the cumulative value of mechanical errors due to the gaps between them. There is a problem.

という問題もある。In addition, when the disk wheel is rotated at a predetermined speed or more in relation to the contact between the contact and the bead seat and the flange surface of the disk wheel as the test body, for example, unevenness smaller than the diameter of the contact roller Is present on the contact surface, the contact roller is separated from the surface, and accurate measurement cannot be performed. Therefore, it is difficult to reduce the measurement time.
更に、試験体であるディスクホイールは、塗装されてい

う欠点もある。Further, the disc wheel, which is a test body, is often painted, and there is also a drawback that a so-called body part where the paint locally hardens is detected as a distortion (deflection) as it is.
更にまた、接触子の接触騒音が発生するという欠点もあ
る。Furthermore, there is a drawback that contact noise of the contact is generated.

なった。<Effect> As described above, according to the present invention, the radial runout of the bead seat and the axial runout of the flange surface adjacent to the bead seat are respectively detected by the non-contact displacement sensor,
Since it was configured to correct the detection error of the radial runout of the bead seat due to the axial runout of the disk wheel, the measurement was made in comparison with the conventional contact type measurement based on Japanese Patent Publication No.50-35282. Since the value does not include the cumulative value of mechanical error and it is not necessary to consider the adhesion to the test piece, the test piece can be rotated at high speed and more accurate measurement can be performed in a short time. Became possible. Further, since the body part of the paint is not detected as a strain, a more accurate measured value can be obtained. Further, since it is non-contact, noise is not generated during measurement, and at the same time, it is possible to perform stable measurement over a long time without consumption by contact as in the conventional case.
