Three-dimensional combined transmission mechanism

Abstract

The invention discloses a multifunctional three-dimensional combined transmission teaching aid. A three-dimensional combined transmission mechanism comprises a rotating wheel mechanism used for conveying a small ball, a simple four-bar mechanism capable of switching two routes, a vertical route switching rotating wheel, a horizontal route switching rotating wheel, a cam ejector used for ejecting the small ball into a collection basket, a crank rocker type lifting device used for lifting the small ball, a multi-rod lifting mechanism, a chain wheel type carrying and lifting device, a cam intermittent lifting device, a pulley block lifting device and a base. With the movement of the small ball in the three-dimensional combined transmission mechanism as the clue, the movement laws of various mechanical structures such as a link mechanism and a cam mechanism are shown in a three-dimensional mode. The three-dimensional combined transmission mechanism is composed of multiple modules, autonomous design, combination and connection of the transmission module are conducted by taking the movement speed and the movement height of the small ball into consideration for each module, the theory of the mechanical structure and practical teaching supplement each other, and an open and interactive teaching atmosphere is formed; the method for displaying various types of mechanical transmission in a three-dimensional mode is adopted, and the optimal demonstration and teaching effect of the combined transmission mechanism is achieved by regulating parts inside all the modules.

Description

technical field [0001] The invention relates to a multifunctional three-dimensional combined transmission teaching aid. Background technique [0002] Teaching aids is an inseparable part of education, and the rise and fall of teaching aids reflects the rise and fall of education. The future and destiny of teaching aids are closely related to the country's politics, economy and culture, especially education. The overall situation determines the small situation. It is true that some teaching aids are relatively simple, but not all of them are "simple". Although some teaching aids with complex structures and functions are relatively expensive, they are indispensable. They have functions that simple teaching aids cannot do; teaching aids are not only for displaying knowledge, but also for cultivating students' innovative thinking and hands-on ability. Up to now, designing and making teaching aids by yourself is still a good way to consolidate knowledge and exercise thinking; en...
