Abstract

The present invention discloses a portable gear drive and processing demonstration instrument. The portable gear drive and processing demonstration instrument comprises a rack, a generating motion chain configured to drive the autorotation of a gear drive wax blank, a cutting motion chain configured to drive the rotation of a hob and a feed motion chain configured to drive the motion of the hob along the vertical direction. Because the mechanism of the portable gear drive and processing demonstration instrument is abundant, the portable gear drive and processing demonstration instrument may be used for displaying driving of common gears for students at mechanical subject classes, may be used for allowing students to do gears having different number of teeth by themselves, and may be also used for allowing the students to more vividly understand the undercutting phenomenon when an undercutting gear is processed. Therefore, through adoption of the portable gear drive and processing demonstration instrument, the class becomes more active, lively and interesting; and moreover, the portable gear drive and processing demonstration instrument is applicable to most of teaching of mechanical subjects and is able to allow students deeply understand the gear drive principle and the gear processing principle.

Description

technical field [0001] The invention relates to a teaching instrument, in particular to a portable gear transmission and processing demonstration instrument. Background technique [0002] With the continuous development of modern university education, classroom expressions emerge in endlessly. However, it is particularly difficult to demonstrate and explain the principles of mechanical principles in mechanical courses, especially professional basic courses. The gear transmission and its processing principle are more important chapters of mechanical principles. At present, there is still a lack of a portable device that can demonstrate gear transmission and its machining process in the classroom. In the traditional teaching process, the teacher can only abstractly explain the gear transmission and its processing principle to the students or play similar videos of the gear transmission and the processing process, which makes it difficult for the students to understand. Now ...
