Supporting tr*ning guide, including system working principles, tr*ning subjects, fault setting and clearing and other key points. 15. 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 bevel gear reducer: After entering the software, the assembly content is automatically played. Each step in the video has a text description . Secondary 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 names of parts), disassembly and assembly demonstration (including disassembly and assembly), virtual disassembly (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. By clicking on the parts, the names of the parts are displayed, and the 360° view is av*lable Rotate, zoom in, zoom out, pan, and move parts to disassemble and assemble the entire reducer. At the same time, you can select the home button to return to the original state of the reducer. The bevel gear reducer and the 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.
