Embodiment Construction

[0023] Such as Figure 1-12 , the comprehensive experimental platform for a dynamic differential gear train, the comprehensive experimental platform uses a children's car as a carrier, and includes a frictional slip resistance increasing device, a swing arm device, a shaking head device and a dancing lower limb device, figure 1 Among them, the two small support wheels that are connected with the rear wheel of the children's car to prevent the dolly from falling are not shown.

[0024]In order to dynamically simulate the differential principle of the differential in real time, the frictional slipping method is used to simulate the friction force of the car on the two wheels during the turning process, so as to achieve the differential speed of the two differential wheels of the differential 6. Purpose. The frictional slip resistance increasing device is mainly composed of a slider crank mechanism 5, a resistance increasing mechanism and a differential mechanism. The different...

Abstract

The invention relates to a dynamic differential gear train comprehensive experiment platform, which is characterized in that the platform is mainly formed by a friction slip resistance increase device, a differential device, an arm swing device, a head shaking device and a lower limb dancing device. When running with joy (with a robot shaking its head, swinging its arms and moving its lower limbshappily), the platform, with a child bicycle as a carrier, not only can simulate the working principle of a differential dynamically and exaggeratedly, but also can lively and vividly demonstrate theworking process of an incomplete gear train, a four-bar mechanism and chain drive, so that students are allowed to play in the study and study in the play, and an effect of attaining the result with half effort is achieved; and in the process of teaching in joy, the platform demonstrates the differential velocity principle of the differential and the like to the students vividly and lively, and isa comprehensive experiment platform, which is extremely high in practicality and fun and entertainment. The platform is a dynamic teaching aid and a merry toy for children, and has a good applicationvalue and market prospect. The set of experiment device is novel in structure, high in knowledge comprehensiveness, simple to operate and low in cost.

Description

technical field [0001] The invention belongs to a teaching aid for mechanical principles, in particular to a dynamic comprehensive experimental teaching aid for differential gear trains. Background technique [0002] Teaching aid reform in the 21st century is based on the comprehensive promotion of quality education as the core, and the implementation of innovative education and practical education as the main educational model. However, there are still many problems in the current educational development. Taking mechanical experiments as an example, the content of mechanical experiments in many schools in our country is boring, the form is single, lack of freshness, dynamics and entertainment, and the teaching aids are insufficient, the experimental equipment is outdated and dull, and students only do experiments mechanically. The nature is completely inconsistent, so it cannot effectively stimulate students' interest in learning, so that the teaching work cannot be carried...
