Embodiment Construction
[0030] The invention is a method for measuring the radius of curvature of a tapered roller. The invention uses a laser displacement sensor to measure the radius of curvature of two sections of different circular arcs at the same height of the tapered roller, and then uses the least square method to fit the radius of curvature at the height. , Repeat the same process to measure the radius of curvature at other heights, so as to calculate the total radius of curvature of the tapered roller, and judge whether the total radius of curvature meets the design requirements.
[0031] combine figure 1 , the method of the present invention uses a set of measuring devices, the measuring device includes a base 1, a two-dimensional mobile movable frame 2, a bracket 3, a laser displacement sensor 4, a clamping sleeve 6, an air bearing turntable 7, and an air bearing 8 And the servo motor 9, the rotation angle and the rotation speed v of the servo motor 9 1 and v 2 are controlled by compute...
