Combined quick-changing type transmission mechanism teaching aid

Abstract

The invention discloses a combined quick-changing type transmission mechanism teaching aid, and belongs to the field of education teaching instruments or demonstration tools. The teaching aid comprises a motive power platform and a transmission mechanism, wherein the motive power platform comprises a vertically arranged fixed panel; a motor, a worm and gear component, a bevel gear component, a chain wheel and an output shaft are arranged on the fixed panel; the worm and gear component is positioned right above the motor and is connected with a motor belt; the worm and gear component is in shaft connection with the bevel gear component; the chain wheel and the bevel gear component are arranged relative to the fixed panel and are in shaft connection with each other through the bevel gear; the chain wheel is connected with the output shaft through a chain; and the output shaft is connected with the transmission mechanism. Tape transmission, worm and gear transmission, bevel gear wheel transmission and chain transmission are performed on the motive power platform. Through the adoption of the various combinations, the teaching aid has the advantages that various experimental demonstrations such as gear train, crank connecting rod and sliding block and gear show processing can be realized; the experimental devices can be demounted and mounted quickly; and the mechanical transmission experiment teaching is facilitated.

Description

technical field [0001] The invention relates to a teaching tool for a transmission mechanism, which belongs to the field of educational teaching instruments or demonstration tools, in particular to a combined quick-change transmission mechanism teaching tool. Background technique [0002] The basic task of the transmission system in machinery is to transmit the movement and power of the prime mover to the actuator. Common mechanical transmissions include belt transmission, chain transmission, gear transmission and screw transmission. In order to make students more intuitively understand the characteristics of these four commonly used transmissions , working principle and structure, teaching aids that can demonstrate these four kinds of transmissions are generally used in teaching, and teaching aids for separate demonstrations are not convenient for students to watch and compare various mechanical transmissions at the same time, and also increase teaching costs.

AI Technical Summary

Problems solved by technology

This structure combines several mechanical transmissions into one, which must be demonstrated at the same time, and a single experimental demonstration cannot be realized, and the entire teaching aid is only for demonstration, and students cannot be disassembled by hand, which limits students' understanding and learning
