1) Description of Helical Gear Shaft
The helical gear shaft is a mechanical part that integrates the helical gear and the shaft, and the gear teeth are at a certain spiral angle with the axis,
which realizes the meshing transmission with other gears through the support of the shaft.
2) Advantage of Helical Gear Shaft
The structure is compact, the gear and shaft have no relative movement, and can withstand large axial and radial forces.
The existence of the spiral angle makes the gears meshed with high degree of coincidence, smooth transmission, and low impact and noise;
The overall rigidity is good, which can reduce the failure caused by loose connections.
3) Working Principle
When the power is input, the helical gear shaft mesh with the gear teeth of the paired gear through the spiral surface of the gear teeth,
transmitting torque and speed from one shaft to another.
4) Application of Helical Gear Shaft
It is often used in machine tool spindles, intermediate shafts of automobile gearboxes, etc., where the compactness of the structure
and the stability of transmission are high.
