The tooth shape of elliptical arc tooth line cylindrical gears is elliptical arc, and the size of tooth width is also an important factor affecting the tooth shape of elliptical arc tooth line cylindrical gears, while ensuring a certain tooth line radius.
When b ≤ RT, the tooth line advantages of elliptical arc tooth line gears cannot be fully demonstrated, and their performance in all aspects is similar to that of straight cylindrical gears; When b>RT, the tooth line of the elliptical arc tooth line cylindrical gear is too prominent, causing the normal thickness on both sides of the gear teeth to be much smaller than the normal thickness in the middle of the gear teeth, resulting in poor rigidity of the gear teeth and affecting transmission stability.
Therefore, it is necessary to study the tooth width of cylindrical gears with elliptical arc tooth lines.
