Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The present invention is to realize the space-saving, material-saving, convenient and flexible design requirements of the "wheel train compound transmission time meter", which is easy for students to learn and understand. The wooden board with a very small area is used as the bottom board, which is convenient for teachers to carry it to class. The "gear train compound transmission chronometer" is generally composed of a fixed-axis gear train and two epicyclic gear trains. When the fixed-axis gear train is driven, the rotation axis of all gears has its fixed position. It can not only do long-distance transmission and obtain a larger transmission ratio, but also verify whether multiple transmission ratios can be obtained by changing the driven wheel. . It is precisely by using the good characteristics of the fixed-axis gear train that ...

Abstract

The invention discloses a composite gear transmission time instrument teaching aid, wherein a first gear is meshed with a second gear and an eleventh gear; the second gear, a third gear, a fourth gear, a fifth gear, a sixth gear and a first annular gear are meshed sequentially; the first annular gear is fixed; the sixth gear is connected with a shaft of an eighth gear by a connecting rod; the eighth gear, a ninth gear and a tenth gear are meshed sequentially; a first pointer is arranged on the tenth gear; the eleventh gear, a twelfth gear, a thirteenth gear, a fourteenth gear, a fifteenth gear, a sixteenth gear and a second annular gear are meshed sequentially; the second annular gear is fixed; the sixteenth gear is connected with the shaft of an eighteenth gear by the connecting rod; the eighteenth gear, a nineteenth gear and a twentieth gear are meshed sequentially; and a second pointer is arranged on a transmission shaft of the twentieth gear. The invention has the benefit that the provided composite gear transmission time instrument teaching aid can demonstrate the inter-gear mechanical transmission principle well.

Description

technical field [0001] The invention belongs to the technical field of teaching aids, and relates to a gear train compound transmission time meter teaching aid. Background technique [0002] With the development of the country and the teaching background of the current society, knowledge is becoming more and more important. It is very important for students to master certain theoretical knowledge during school, especially for students majoring in mechanical engineering. . Because mechanical knowledge is difficult to understand and difficult to understand, only certain teaching aids can enable teachers to teach more clearly, and also enable students to grasp and use this knowledge more clearly. [0003] This "Gear Train Compound Transmission Time Meter" is designed to enable students to have a good understanding of mechanical knowledge in the classroom: such as the direction of the gear train transmission, how to quickly find the gear ratio of the gear train, what is the str...
