Embodiment Construction

[0018] The structural arrangement of the patent of the present invention is as follows figure 1 It is a cubic box-shaped structure, in which the gears on the six sides are arranged on the box surface, and the specific arrangement on each surface is as follows: figure 2 shown. Put down support leg 17 during use and can show the cylindrical spur gear on the surface 2,3,6,7, bevel gear, parallel shaft helical gear, planetary gear train. Putting up the supporting legs 17 and putting down the supporting legs 16 can display the worm and worm gears and the cross-axis helical gears on the surfaces 4 and 5, which are visually independent and do not interfere with each other. The teacher only needs to rotate the gear on any one surface, that is, the driving gear on the display surface facing the students can be driven to rotate at the same rotational speed, and the operation is convenient.

Abstract

The invention relates to a teaching aid for demonstrating gears in six-sided mode and belongs to the field of teaching apparatuses. The teaching aid mainly consists of a box body, six types of basic gears, a central gear train linkage mechanism and supporting legs. The box body is of a cubic structure, six types of basic gears are arranged on the box faces, a gear shaft of a driving gear extends into the center of the box body, and a bevel gear at the shaft tail end form the central linkage mechanism. The supporting legs are arranged on two surfaces of the box body and support the teaching aid during demonstration. On the premise that the visual burden is not brought to students, integrated demonstration of various gears is achieved, and meanwhile creative teaching functions of six-sided linkage, independent exploration assembly, transmission ratio demonstration and the like are achieved.

Description

technical field [0001] The patent of the present invention relates to a teaching instrument, in particular to a gear teaching tool used in mechanical courses such as "mechanical principles". Background technique [0002] At present, courses such as "Principles of Machinery" and "Fundamentals of Mechanical Design" all involve chapters on gears, and the teaching of the corresponding parts includes the transmission characteristics of various types of gears and the distinction of various types of gear trains. However, the existing gear teaching aids generally have the disadvantages of single function and less applicable teaching content, which increases the teaching burden of teachers and affects the teaching effect. Contents of the invention [0003] Aiming at the shortcomings of the existing gear teaching aids, the patent of the present invention provides a gear display teaching aid more suitable for teaching. [0004] The purpose of the patent of the present invention is a...
