1) Description of Helical Gear Shaft
In powertrains, helical shafts are a critical component for efficient power transmission through helical meshing,
and their gears are designed to optimize the transmission path of force.
2) Advantage of Helical Gear Shaft
High transmission efficiency, due to the relatively smooth meshing process of wheel teeth, less energy loss;
It can transmit a large amount of power, and under the same size, it transmits more power than a spur gear shaft;
The transmission efficiency and axial force can be adjusted by changing the spiral angle.
3) Working Principle
The power is transmitted to the helical gear shaft through the input end, and the spiral structure of the gear teeth
makes the meshing point gradually enter and exit the meshing, and the force transmission is carried out gradually,
reducing energy loss, so as to efficiently transmit power to the driven parts and achieve smooth transmission of power.
4) Application of Helical Gear Shaft
It is widely used in the transmission system of cranes, the power transmission device of mining machinery,
and other equipment that needs to transmit high power efficiently.
