Tiivistelmä
The objective of this Bachelor’s thesis is to examine different manufacturing methods, heat treatment and material options for small spur gears. The thesis was commissioned by Metropolia Motorsport Formula Team and is intended to be used as a guide for further developing the team’s 4-wheel drive racecars drivetrain system.
Before the research process a baseline was established by going through the initial plans for the stepped planetary gear intended to be used in the season 2020 racecar.
The process of this thesis was started by familiarizing with both classic gear manufacturing literature as well as more contemporary manufacturing methods. Based on this research significant values for the strength of spur gears were catalogued and presented per each heat treatment method. Manufacturing methods were researched and recorded with notes on their qualities.
These findings were further narrowed down to form the results. Materials for manufacturing were considered during the research but they were not a deciding factor, as most materials are readily available for Metropolia Motorsport through their partners and sponsors.
As a result, a table and more detailed information about three different manufacturing methods were compiled according to the findings from the research in this thesis. In addition, several finishing methods in gear manufacturing were considered and recorded in a table. The complexity of gear manufacturing was clarified and a few suggestions for further development are given in the conclusions.
