(1) Good meshing performance: the meshing process between helical cylindrical gear teeth is an excessive process, and the force on the teeth is gradually from small to large, and then from large to small; Helical gears are suitable for high speed and heavy load.
(2) Large coincidence degree: the increase of coincidence degree improves the bearing capacity of the gear. Thus, the service life of the gear is prolonged. The coincidence degree mainly depends on the meshing time, while the helical gear has long meshing time and large contact area, which reduces the stress. It makes the transmission stable and increases its economy.
(3) Compact structure: the less the minimum number of teeth, the more compact the structure is.
