Ordinary gear train and epicyclic gear train function display and contrastive analysis platform

Abstract

The invention belongs to the fields including gear train combination comprehensive analysis and teaching instrument technologies and discloses an ordinary gear train and epicyclic gear train function display and contrastive analysis platform which is mainly applied to mechanical principle teaching for science and engineering students in colleges and universities. The platform mainly solves the problems of teaching complanation and experimental unicity. The platform is composed of an ordinary gear train unit, a planetary gear train unit, a differential gear train unit, an epicyclic gear train unit and a power shunting unit, wherein the ordinary gear train unit mainly displays ordinary gear train transmission ratio calculation and determination of the steering relation between the head wheel and tail wheel of an ordinary gear train, the differential gear train unit mainly displays composition and decomposition of motions of a differential gear train, the planetary gear train unit and the epicyclic gear train unit mainly display the functions of an epicyclic gear train and the influence of tooth number change on the transmission ratio, and the power shunting unit mainly displays the application of the gear trains. By the adoption of the platform, students can grasp the basic theory, basic knowledge and basic skills of the mechanical principle and develop the capacity for mechanical motion scheme determination and mechanism analysis and design preliminarily.

Description

technical field [0001] The invention is mainly used in the teaching of mechanical principles of science and engineering in colleges and universities, and belongs to the fields of comprehensive analysis of wheel train combinations, teaching instrument technology and the like. Background technique [0002] In the current experimental teaching, especially in the experimental teaching process of gear trains, there are mainly two teaching methods, one is to use animation simulation to demonstrate the movement relationship of each mechanism, and students cannot experience the movement relationship in person; The other is to use the physical model to demonstrate statically, and students cannot understand the transmission relationship of each component. [0003] The characteristics of various gears, the calculation method of transmission ratio, and the combination function of gear trains are described in the current university mechanical design courses; in the experimental teaching ...

AI Technical Summary

Problems solved by technology

However, this is only an abstract description in the book, and in the experimental session, students cannot assemble and design the wheel train combination by themselves, and cannot explore the differences between various wheel trains

Generally speaking, at present, the content of mechanical courses set up by various colleges and universities is abstract, students lack interest in learning, and the operability of experimental demonstration equipment is not strong, and most of them are placed in the laboratory. It is also relatively rigid, has no sense of reality, and cannot arouse students' interest in learning

Therefore, there is currently a lack of a new type of teaching aid that integrates physical display, motion analysis, experimental exploration, multi-knowledge point explanation, and students' independent design and assembly.
