Problems solved by technology
[0009] In the teaching process, usually teachers have to explain the cycloid in the parameter equation, and try their best to describe the formation and trajectory of the cycloid by drawing the cycloid on the blackboard. Since it cannot be described by simple drawing, it causes intuitive teaching difficulties

The invention discloses a cycloid trajectory display device. The cycloid trajectory display device includes a base, a first rotation wheel, a second rotation wheel and an eccentric transmission mechanism; a guide rail and a rack are arranged on the base, the guide rail is arranged horizontally, a sliding block capable of being slidably mounted is arranged on the guide rail, a first rotation shaftis vertically arranged on the sliding block, the first rotation wheel and the first rotation shaft are arranged coaxially, the first rotation wheel can be rotationally mounted on the sliding block through the first rotation shaft, a first tooth part is arranged at the periphery of the first rotation wheel, the rack is horizontally arranged at one side of the first rotation wheel, and the side, facing the first rotation wheel, of the rack is provided with a second tooth part meshing with the first tooth part; the second rotation wheel is coaxially arranged above the first rotation wheel and isfixedly connected with the first rotation wheel, and a hatching pen is arranged on the first rotation wheel and is located at the side, where a rotation shaft is located, of the first rotation wheel.By the adoption of the cycloid trajectory display device, a cycloid forming process is clearly displayed, and therefore visitors' or learners' perception on the formation and trajectory of a cycloid is greatly promoted.
Description
technical field [0001] The invention relates to the technical field of trochoid drawing, in particular to a trochoid track demonstration device. Background technique [0002] When a circle rolls on a fixed line, the trajectory of a fixed point on the circumference is also called circular rolling line and cycloidal line. [0003] The initial position of the fixed point on the circle is the coordinate origin, and the fixed line is the x-axis. After the circle rolls j angle, the fixed point on the circle reaches the point P from the O point. When the circle rolls a circle, that is, when j changes 2π from O, the fixed point on the moving circle draws the first arch of the cycloid. Roll forward for another week, draw the second arch at a fixed point on the moving circle, continue to roll, you can get the third arch, the fourth arch..., all these arches have exactly the same shape, and the arch height of each arch is 2a (i.e. the diameter of the circle), the arch width is 2πa (...
