Embodiment Construction
[0016] In conjunction with the accompanying drawings, the specific description is as follows:
[0017] Such as figure 1 As shown, 1 incident beam, 2 reflected beam, 3 curved mirror.
[0018] The angle between the incident beam and the normal of the reflected surface is 45 degrees, and the direction is from right to left. The angle between the reflected beam and the normal of the surface is also 45 degrees, and the direction is from top to bottom. The gear radius is set to unit 1, that is, R=1, thickness L=0.2 (unrestricted), number of teeth N=8, the distance from the incident beam direction to the center of rotation is 0.7071, and the angle formed by each curved mirror to the center of rotation is 36 degrees, the reflected light beam is translated between the gears by H=0.2. Establish a local coordinate system on a tooth, the coordinate origin is at the tooth tip, the y coordinate is along the opposite direction of the gear radius, and the x coordinate is along the vertical ...
