Embodiment Construction

[0022] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0023] Including bevel gear transmission module, cylindrical gear transmission module and planetary gear train module.

[0024] The bevel gear transmission module is composed of a handle 1, a small bevel gear 13, a large bevel gear 14, a first shaft 2, a second shaft 4, a first base 3 and a second base 5; the handle 1 and the first small bevel gear 13 are respectively fixed Installed on both sides of the first shaft 2, the user shakes the handle 1 to rotate, driving the first shaft 2 and the first small bevel gear 13 to rotate, the small bevel first gear 13 meshes with the large bevel first gear 14, and passes through the second The transmission of the shaft 4 transmits the motion to the cylindrical gear module to drive the rotation of the first cylindrical gear 15 .

[0025] The cylindrical gear transmission module consists of guide rail 17, first cyl...

Abstract

The invention discloses a comprehensive gear train training aid for a mechanical principle, and relates to the related field of mechanical subject teaching. The comprehensive gear train training aid comprises a bevel gear transmission module, a cylindrical gear transmission module and a planetary gear train module. The relevant knowledge points of the mechanical principle gear chapter are covered; comprehending of students on gear transmission can be deepened; different rotation ratios can be obtained by adjusting the position of a gear base or a movable planet wheel shaft; the gear transmission process is relatively intuitively displayed; learning and the comprehending of the students are facilitated; and meanwhile, the interestingness of classroom teaching is increased. Compared with an existing teaching aid, by using the training aid disclosed by the invention, the knowledge is relatively comprehensive; through the combined transmission of a bevel gear, a cylindrical gear and a planetary gear train, the structure is simple; the comprehending is facilitated; the defects that in traditional teaching, focus is input on theory, and the content is boring are compensated; and the comprehensive gear train training aid conforms to the idea of modern education.

Description

technical field [0001] The invention relates to teaching aids for mechanical principles course teaching aids for mechanical majors, in particular to a comprehensive gear train teaching aid for mechanical principles. Background technique [0002] "Mechanical Principles" is an important basic course for mechanical majors in colleges and universities. It is a key course for students to learn mechanical professional knowledge well. Its most notable feature is the combination of basic theory and engineering practice. However, traditional classroom teaching focuses on theory. Most of them are mainly taught by teachers. Traditional demonstration teaching aids have single functions, fixed content, boring process, and lack of change, so it is difficult to stimulate students' interest in learning. [0003] The current teaching aids for mechanical principles mainly include: gear tooth profile processing demonstration teaching aids, four-link movement demonstration teaching aids, cam de...
