SL-JZB Portable Mechanical System Transmission Innovation Combination Design Experiment Bench

The purpose of using the experimental box
The mechanical transmission device is the main component of the machine or unit and plays an important role in transmitting power or changing motion. Selecting the transmission type according to needs and combining a reasonable mechanical transmission scheme are important contents in the teaching of "Mechanical Design" course.
The purpose of use is to
deepen the perceptual and theoretical understanding of various types of mechanical transmission
By assembling various combined transmission schemes, the transmission characteristics of different schemes can be comparatively analyzed. This experimental box is An ideal platform for cultivating students' innovative abilities
This experimental box is portable, can be electric or manual, and can be configured in an open laboratory. Students can also borrow it and use their spare time to assemble it to improve students' hands-on ability and interest in learning.
Second Experiment Content
Assemble various types of mechanical transmission combinations, observe various single-stage transmissions, and analyze their transmission principles and characteristics
Comparatively analyze the characteristics of different combination transmissions.
Introduction to the three experimental boxes
Experimental box configuration and main technical parameters This experimental box is equipped with various self-made parts, standard parts and purchased parts, as well as various assembly tools. Most of the parts in the box are made of hard aluminum alloy, which has high processing precision and is light and convenient to use. The workbench panel is made of hard aluminum profiles with grooves, making assembly easy and fast. The names, quantities and main technical parameters of various parts are shown in the attached table.
Assembly scheme Dozens of mechanical transmission schemes can be assembled using the parts equipped in this experimental box, the main ones are
Single-stage transmission belt transmission chain transmission cylindrical gear transmission bevel gear transmission sheave mechanism single cross universal coupling transmission, etc.
The transmission is designed based on the precision lathe transmission. The manual sliding sleeve makes the two or three gears slide along the two spline shafts respectively. Through the meshing of different gears on the three transmission shafts (two spline shafts and one flat key shaft), the step transmission ratio can be obtained. The three transmission shafts can be arranged in a triangle or in a spread arrangement. Remove the flat key shaft and install the intermediate wheel shaft and intermediate wheel to obtain a gear transmission containing the intermediate wheel.
Multi-stage combined transmission can select two or more of the above-mentioned single-stage transmissions and transmissions, and use couplings or clutches to connect them to form a multi-stage combined transmission.
