Method for measuring side run-out of wheel

摘要

A method for measuring side run-out of a wheel by turning the wheel mounted on a roller supported rotatably. It is judged whether or not the difference between the side run-out of a wheel at the start point onf one turn and the end point of one turn falls within a specified range or not. If it falls within the specified range, the difference between the maximum and minimum values of the side run-out during rotation is defined as the side run-out of the wheel. Even if the wheel is displaced during measurement to cause variation in the measurement value of the side run-out, the varied measurement value can be removed and highly accurate side run-out and side run-out width can be obtained.
