Agricultural Machinery Started Electrical Training Desk

The device adopts the actual object of the 750P tractor starting system to fully display the structure and work process of the starting system.

It is suitable for the teaching needs of school theory and m--ntenance tr--ning for starting systems.

2. Functional characteristics

1. Real and running starting system, fully display the composition of the starting system.

2. Manipulate the starting switch, start motor work, and realize the work process of the starting system. The process of starting the current and battery voltage during the starting process can be observed through the current meter and voltage meter on the panel.

3. The panel adopts a ** aluminum -plastic plate with 4mm thick corrosion, strike, pollution resistance, fire prevention, and moisture -proof, and the surface is sprayed with primer p--nt by special crafts; the panel prints with color circuit diagrams that will never fade; students can intuitively compare the circuit diagram of the circuit diagram And real, understand and analyze the working principle of the car starting system.

4. There is a total motivation component on the panel, which can intuitively understand the constituent structure of the starting motivation.

5. The detection terminal is installed on the panel to detect the electrical signals of the circuit components of the starting system directly on the panel, such as resistor, voltage, current, frequency signals, etc.

6. The panel part uses a 1.5mm cold plate stamping and forming structure, which is beautiful in appearance; the bottom part is welded with steel structure, the surface is treated with spraying process, a self -locking wheel device, and a desktop of about 40cm on the base of the teaching plate, which is convenient for placing. Data, light detection instruments, etc.

7. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D. It can select 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical institutions, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.

A. Turbine design and virtual disassembly interface can be selected from turbine sn--l pole cone gear reducer, second -level pilot gear reducer, conical cylindrical gear reducer, coaxial cylindrical gear reducer, cone gear reducer, first -class cylindrical, first -class cylindrical, Gear reducer.

The gear transmission intensity design is one of the important chapters in the "Mechanical Design" course. The experimental device has not been comprehensively tested and analyzed for the bending strength and contact intensity of gear transmission at home and abroad. A blank provides an indispensable experimental equipment for mechanical students to deeply understand the strength of gear transmission strength design.

Experimental project content:

1. Understanding, observation and analysis of the working principle of the mechanical transmission ch--n and the structure of the component structure, and disassemble the experiment.

2. The understanding of the electrical signal control and transmission ch--n of the experimental desk, observation and analysis of the principles of work.

3. Operation experiment:

(1) Calculation calculation of the tooth root bending intensity of str--ght tooth and oblique tooth cylindrical gear transmission;

(2) The stress testing and comparative analysis of the stress test and comparative analysis of the stress test and comparative analysis of the str--ght tooth cylindrical gear and the oblique cylindrical gear at the same center;

(3) Stress testing and comparative analysis of stress testing and comparative analysis of different loads and equivalent loads at the same speed;

(4) Stress test and comparative analysis when the load is equal to different speeds;

(5) Battle and force analysis of gear transmission ch--n.

M--n technical features:

1. Using an equivalent test method with no damage to the contact surface to solve the problem of measuring the contact stress of the tooth surface, and using the str--n test method to test the bending stress of the tooth to fill the gap at home and abroad.

2. The bending str--n of the wheel teeth and the signal of the contact str--n adopt a non -declining rotor to make the collection signal the real, stable, and reliable.

3. The experimental desk is equipped with a special comprehensive analysis software. Students can independently carry out the gear transmission strength comprehensive design under the guidance of the software, and assemble the gear transmission based on the design parameters. Dedicated software can automatically process and save data, draw experimental curves and have printing functions.
