1)Descriptions of Helical Gear
Helical gears are a type of gear that optimizes the distribution of force through their helical teeth,
and are capable of withstanding greater loads.
2)Features of Helical Gear
a)Axial thrust will be generated during the meshing process.
b)The load is distributed across multiple teeth, resulting in a larger contact area.
c)The helix angle can be adjusted as needed (usually between 15 and 30 degrees).
3)Advantages of Helical Gear
a)The load-bearing capacity is 20-30% higher than that of the same-sized straight gears.
b)Longer service life: Evenly distributed load reduces local wear and tear.
c)Suitable for high-speed operation: The maximum linear speed can reach 1.5 times that of spur gears.
