A comprehensive display teaching aid for transmission mechanism

Abstract

The invention discloses a typical transmission mechanism comprehensive demonstration teaching aid. Mechanical theories are high in theoretical property, most of motion forms are hard to image, and mechanical theory teaching aid models in laboratories are inconvenient to carry to classrooms and high in price. The typical transmission mechanism comprehensive demonstration teaching aid comprises a demonstration box, a crank rocker mechanism, a planar four-bar mechanism evolution mechanism, a cam mechanism, a gear mechanism, a gear train mechanism, a ratchet wheel mechanism, a sheave mechanism and a control module. The bottom of the demonstration box is provided with support legs, and the top of the demonstration box is provided with a handle; the crank rocker mechanism, the planar four-bar mechanism evolution mechanism, the cam mechanism, the gear mechanism, the gear train mechanism, the ratchet wheel mechanism and the sheave mechanism are all arranged on the side surfaces of the demonstration box and respectively powered by a servo motor arranged inside the demonstration box, and every servo motor is provided with a motor switch. By means of mechanical-electrical integration and through the wireless transmission technology, the typical transmission mechanism comprehensive demonstration teaching aid enables a typical transmission mechanism to move really and meanwhile helps detect the parameters of a motion mechanism for facilitating quantitative analysis.

Description

technical field [0001] The invention belongs to the field of teaching instruments, and in particular relates to a comprehensive display teaching aid for a transmission mechanism. Background technique [0002] Mechanics Principles is a subject that studies institutions and machines. It is a technical basic course that plays an important role in paving the way for the in-depth study of mechanical subjects in the future. However, such an important basic course makes many mechanical students quite a headache. After investigation, it was found that the mechanical principles were too theoretical, and it was difficult to imagine many forms of motion, and the descriptions in textbooks seemed boring. Therefore, in the class of mechanical principles, the demonstration and guiding role of teaching aids is very important. It allows students to understand and understand the mechanism more intuitively, and the large-scale mechanical principle teaching aid models in the laboratory are mor...

Problems solved by technology

After investigation, it is found that the mechanical principle is too theoretical, it is difficult to imagine many forms of motion, and the description in textbooks seems boring

Therefore, in the class of mechanical principles, the demonstration and guiding role of teaching aids is very important. It allows students to understand and understand the mechanism more intuitively, and the large-scale mechanical principle teaching aid models in the laboratory are more suitable for visiting. Inconvenient to carry to class to interact with classmates, and expensive

Teaching aids for a single demonstration of a mechanism, single function and cannot be quantitatively analyzed
