1) Descriptions of Helical Gear
The gears that transmit power and change motion through helical tooth profiles are called helical gears.
During their operation, the contact between the teeth is of the line contact type.
2) Advantages of Helical Gear
a) Stable transmission ratio: During the transmission process, due to the special shape of the gear teeth of helical gears,
the transmission ratio can be ensured to remain constant, achieving precise speed and torque transmission.
b) Axial force: During the transmission, helical gears will generate axial forces. By reasonably designing
and installing thrust bearings and other measures, this force can be effectively utilized or counteracted,
optimizing the performance of the transmission system.
3) Applications of Helical Gear
It is indispensable in equipment that requires precise transmission ratios, such as clocks, instruments,
and automated production lines; at the same time, in large-scale power transmission equipment,
by reasonably controlling the axial component forces, efficient and stable power transmission can be achieved.
