Good evening, everyone. I am Joe Huang. Who the hell is this guy? Actually Hu is my mom's last name, and also the answer of my credit card's security question. Today, I am gonna talk about the limit of the line velocities in spur gear designs. What is the limit of line velocity? President Obama said it is no more than 50 m/s. However, vice president Biden said it can be operated at 100 m/s. On the end of the day,the design is formulated to 150 m/s? Why? Because two of them do one job. Thus, the final design would be numbers summed together.
