1) Descriptions of Helical Gear
In mechanical engineering design, according to specific transmission requirements and working conditions,
gears with helical teeth are designed, namely helical gears.
2) Advantages of Helical Gear
a) Flexible design: According to different requirements such as transmission ratio, center distance, and load,
the parameters of helical gears, including module, number of teeth, and helix angle, can be flexibly designed
to meet diverse engineering needs.
b) Optimize system performance: By reasonably designing helical gears, the structural layout of the entire mechanical
transmission system can be optimized, reducing the size and weight of the equipment,
and improving the overall performance and reliability of the system.
3) Applications of Helical Gear
During the research and design stage of mechanical products, helical gears are an important choice for engineers
to achieve efficient transmission and compact structural design. They are widely used in numerous engineering fields
such as automobiles, ships, and wind power generation.
