POWERTRAIN AND VEHICLE DYNAMICS
Introduction
Gearboxes are essential components in many mechanical systems, including automobiles, motorcycles, and power tools. They allow for the transmission of power from one shaft to another, and they can also be used to change the speed or direction of rotation.
In this assignment, you will be designing an engine gearbox for a specific application. You will need to consider the following factors:
• The type of engine
• The desired output speed and torque
• The number of gears
• The gear ratios
• The layout of the gearbox
Objectives
The objectives of this assignment are to:
• Learn about the principles of gear transmission
• Design a gearbox that meets the specific requirements of an application
• Analyse the performance of the gearbox
Assignment Requirements (100 Marks)
1. Select an engine for your gearbox. This will determine what gearbox considerations you will make.
2. Determine the desired output speed and torque for your gearbox. This will depend on the application of the gearbox.
3. Determine the number of gears for your gearbox. The number of gears will affect the range of speeds and torques that the gearbox can provide.
4. Determine the gear ratios for your gearbox. The gear ratios will determine the speed and torque multiplication provided by each gear.
5. Lay out the gearbox. This will involve determining the location of the gears, shafts, bearings, and other components.
6. Analyse the performance of the gearbox. This will involve calculating the efficiency, torque capacity, and speed range of the gearbox.
Resources
There are many resources available to help you with this assignment. Some of these resources include:
• Textbooks on gear design
• Online tutorials on gear design
• Gear design software
Grading
Your assignment will be graded on the following criteria:
• Completeness of the design
• Accuracy of the design
• Performance of the design
Submission
Please submit your assignment as a report that includes the following:
• A description of your engine and application
• A diagram of your gearbox layout
• A table of gear ratios
• A calculation of the efficiency, torque capacity, and speed range of the gearbox
Deadline
This assignment is due on 23rd November 2023.
Additional Notes
• You are encouraged to explore and innovate in your designs.
