Characteristics Of Cylindrical Gear Mechanisms

During meshing transmission, this gear mechanism exhibits a large tangential relative sliding velocity along the tooth length, resulting in significant wear. Furthermore, the two gear tooth profiles are in point contact, leading to high contact stress. This causes premature pressure feeding of the q-surface, accelerating tooth wear. Compared to parallel-axis helical gears, crossed-axis helical gear mechanisms have significantly lower service life and mechanical efficiency.
