company news about What is the concentricity deviation measuring device and measuring method of railway wheels?

The company has developed a concentricity deviation measuring device and measuring method for railway wheels, which belong to the technical field of concentricity inspection tools. The measuring device includes a positioning frame. A reference positioning part and a concentricity measuring part are provided, the reference positioning part is in conflict with the top of the wheel rim, and the concentricity measuring part is in conflict with the tread rolling circle to measure the radial distance difference between the top of the wheel rim and the tread rolling circle. The beneficial effects of the invention are that the overall structure of the measuring device is simple, the manufacturing cost is low, the concentricity deviation of the wheel can be quickly measured by using the measuring device, the measuring method is simple, and the measuring result is reliable.
