Automatic transmission disassembly and detection training device

The equipment meets the requirements of the "National Vocational College Skills Competition" and "Automobile Automatic Transmission Disassembling and Detective" project competition. It can conduct the tr--ning and assessment of the automatic transmission disassembly and assembly skills.

 

2. Functional characteristics

1. Material:

The overall frame of the device is made of 40 × 40mm high -intensity square steel. It is welded with monomer plates around the steel plate.

2. Foundation:

The device is m--nly composed of the tr--ning table, mesh board, 2T manual bed and hidden deceleration flip mechanism.

The mesh plate is installed in front of the tr--ning table, equipped with a dedicated hook, equipped with special tools to facilitate the use of automatic transmission components and dedicated tools; 2T manual pressing bed is installed on the right side of the tr--ning table for transmission bearing for gearbox bearings. Disassembling operations; drawers with drawers on the front of the tr--ning table for dedicated measurement tools, and the lower part is a component storage cabinet; there is a hidden deceleration flip mechanism on the left side of the tr--ning platform, which can rotate the transmission at any angle and can arbitrarily arbitrarily arbitrarily arbitrarily Location is locked, which is convenient for students to disassemble and assemble from different angles; set up activity oil disks.

3. The device is equipped with Volkswagen 01M automatic transmission assembly (with electronic valve wiring, easy to disassembled), and is installed on a dedicated hidden deceleration flipper.

4. The bottom of the tr--ning table is a self -locking foot wheel and a fixed adjustment bolt, which can be convenient to move and fix.

5. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D, which can choose 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.

The experimental device is used to determine the basic content of the gradual opening gear and its meshing parameters, and verify the basic content in the chapter of "gear mechanism and its design". It is one of the basic equipment of the mechanical principle laboratory

Experimental project content:

1. Graduation of the measurement of str--ght -tooth cylindrical gear parameters.

2. Gradually open the gear meshing transmission demonstration and its weight -scale measurement.

3. Measurement of the type of transmission and meshing parameters.

M--n technical features:

1. Not only can the geometric parameters of a single gradient gear, but also the mesh parameters of the meshing gear, such as overlapping, central distance change coefficient, etc.

2. The measured gears include standard gears, positive position gears, negative variable gears; root -cut gears and non -root cut gears; standard pressure angle (α = 20 °) gears and small pressure angle (α = 15 °) gear ; Normal tooth -made gears and short -toothed gears. Standard gear transmission, height variable gear transmission (equal variable position), angle variable gear transmission (no change, that is, positive transmission and negative transmission).

M--n configuration and technical parameters:

1. 6 gears to be tested, M = 4mm Z = 35, 16, 15, 27, 23, 22 α = 20 °, 15 °;

2. 1 support platform board;

3. 4 pieces of transparent meshing lines;
