Cycloid teaching aid for university mathematics

Abstract

The invention discloses a cycloid teaching aid for university mathematics. The device comprises a frame body. A movable plate body is arranged on one side face of the frame body. Parallel racks are arranged on the two opposite inner side faces of the frame body. A limiting baffle is arranged at the position, close to the movable plate body, in the frame body. A disc rolling body is arranged in the frame body, and the disc rolling body is meshed with the racks. A through groove is formed in the disc rolling body, and the central axis face of the through groove passes through the central axis of the disc rolling body. Sliding rails are fixedly connected to the two sides of the through groove, and a sliding fit frame is arranged on the sliding rails. The sliding rails with scale marks are arranged on the two sides of the through groove, sliding relative to the sliding rails can be achieved through the sliding fit frame, then the position of chalk on the disc is controlled, and cycloid drawing demonstration at all positions is achieved. The sliding fit frame and the sliding rails can be fixed through fixing bolts on the two sides of the sliding fit frame, and a buffering piece arranged in an installation sleeve arranged on the bottom face of the sliding fit frame is used for clamping chalk so as to guarantee that cycloid drawing lines are clear and visible.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a cycloid teaching aid for university mathematics. Background technique [0002] The cycloid is one of the many fascinating curves in mathematics. It is defined as follows: a circle slowly rolls along a straight line, and the trajectory passed by a fixed point on the circle is called a cycloid. In the traditional mathematics teaching simulation, The teacher draws a number of circles on the blackboard with tools, and then reflects the law of the cycloid by finding points to connect the lines. This will invisibly affect the teaching efficiency, and the students' understanding is not very thorough. Some teachers do it after class. Good pictures are displayed during the teaching process. Although it solves the situation that there is no need to draw circles in class to a certain extent, students are not very intuitive in learning and cannot intuitively observe the stroke of the...

Problems solved by technology

[0004] The purpose of the present invention is to provide a cycloid teaching aid for university mathematics to solve the problem of unclear or wrong trajectory caused by the slippage of the end of the chalk during the use of the existing device, the inability to ensure the stability of the device on the blackboard, and the inability to engage the teaching aid in time problems with parts being lubricated
