Agricultural machinery four-wheel steering experimental device

Agricultural machinery four-wheel steering experimental device,Experimental device for testing heat transfer and heat transfer coefficient during steam condensation

1. Product introduction

This equipment is based on the refurbished tractor's four-wheel steering system and comprehensively demonstrates the structure and working process of the tractor's four-wheel steering system.

It is suitable for the teaching needs of tractor four-wheel steering system theory and m--ntenance tr--ning in secondary and higher vocational and technical colleges, general education colleges and tr--ning institutions, and meets the teaching functions of tractor four-wheel steering system structure display, work simulation, disassembly and assembly tr--ning, etc. .

2. Functional features

1. A real and operational tractor four-wheel steering system, fully demonstrating the structure of the tractor's four-wheel steering system.

2. The three-phase motor is used as the power source to drive the power pump to operate the steering wheel and simulate the four-wheel steering process.

3. The base of the tr--ning platform is welded with a steel structure, and the surface is spray-coated. It is equipped with self-locking casters, making it flexible to move, safe, reliable, sturdy and durable.

4. Mechanical assembly and fitter assembly virtual simulation software: This software is developed based on unity3d, with optional 6-level image quality. It is equipped with the design and virtual disassembly and assembly of reducers and shafting structures, the design and simulation of common mechanical mechanisms, and a mechanism resource library. For a typical mechanical mechanism (virtual disassembly and assembly of a gasoline engine), the software is a whole software and cannot be individual resources.

A. Reducer design and virtual disassembly interface can choose worm gear bevel gear reducer, two-stage expanded cylindrical gear reducer, bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, and one-stage cylindrical gear reducer. Gear reducer.

Worm and bevel gear reducer: After entering the software, the assembly content is automatically played, and each step in the video has text explanations.

Two-stage expandable cylindrical gear reducer: After entering the software, the content is played in the form of a video. The video content should include: part name (scan the QR code to see the name of the part), disassembly and assembly demonstration (including disassembly and assembly), virtual disassembly Installation (including overall, low-speed shaft, medium-speed shaft, high-speed shaft, box cover, box seat)

Conical cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, first-level cylindrical gear reducer: click to enter and automatically jump to the edrawings interface. The models are all three-dimensional models. Click on the component to display the component name. , can rotate, enlarge, reduce and translate 360° in all directions. At the same time, the entire reducer can be disassembled and assembled through the moving parts function. At the same time, the home button can be selected to return to the original state of the reducer. The bevel gear reducer and first-stage cylindrical gear reducer have added the function of inserting a cross section, and the cross section can be freely dragged to observe the internal structure of the reducer.
