The training of gear train motion scheme design is a complex task involving many aspects, which needs to take into account many factors, such as the type of gear train, transmission ratio, motion law, connection mode between gear trains, etc. Here are some basic steps and considerations:
1.*Determine the type of gear train**: First of all, you need to determine the type of gear train, such as fixed shaft gear train, rotating gear train, planetary gear train, etc. Different types of gear trains have different characteristics and applications.
2.*Determine the transmission ratio**: According to the requirements, determine the transmission ratio between the wheels. The transmission ratio is the ratio of the number of teeth or diameter of the gear, which determines the speed and direction of movement of the gear train.
3.*Design gear**: According to the type of gear train and transmission ratio, select the appropriate gear material, accuracy level and number of teeth. When choosing gears, factors such as the strength, stiffness, and life of the gears need to be considered.
4.Determine the position of the shafts: Determine the location and number of shafts, and how they are connected to the gears. Consideration may need to be given to the strength, stiffness and life of the shaft, as well as how the shaft fits with the bearing.
5.*Consider the law of motion**: According to your needs, design the movement law of the gear train. This may involve the design of the controller to achieve the desired movement and speed changes.
6.Drawing: Convert a design into a drawing, including the location and connection of gears, shafts, bearings, and other parts. The drawings should be clear and accurate, which is convenient for subsequent manufacturing and assembly.
7.Simulation*** Simulate the design using 3D modeling software or simulation software. This helps to check the correctness and feasibility of the design, as well as to identify potential problems.
8.*Fabrication & Assembly**: Fabricate and assemble according to drawings, ensuring that each part is positioned and connected correctly. During the manufacturing process, there may be some technical issues that may need to be addressed.
9.Test & Adjust: After assembly, test and adjust to ensure that the gear train can move as designed. It may be necessary to adjust the position of some parts or the force of the fasteners.
10.*Maintenance & Maintenance**: After being put into service, regular maintenance and upkeep are required to ensure the normal operation of the gear train.
The test bench highlights the design and comprehensive experiments based on the wheel train and its function.
