1, the transmission is stable:
When a pair of helical spur gears mesh, since the gear teeth are not parallel to the gear axis, the two-tooth tooth profile curved surface is in line with the line inclined with the axis. During the meshing transmission process, the tooth surface contact line is shortened and lengthened. It shortens from length to disengagement.
Therefore, the load on the gear teeth is gradually reduced from small to large, and then the transmission is relatively stable, and the impact, vibration and noise are also small, which improves the stability of the transmission.
2. High carrying capacity:
In the helical gear transmission, due to the inclination of the teeth, when one end of the teeth enters the engagement, the other end has not yet entered the engagement, and when one end of the teeth disengages, the other end continues to engage.
For example, the helical gear transmission with the same end size and width has more logarithmic gears than the spur gear, so the helical gear transmission has a greater degree of coincidence than the spur gear. It can make the transmission smooth and improve the bearing capacity of the gear.
