What are the advantages of helical gear in the automotive and aircraft industry?

Helical gear is one of the most common parts in the automotive and aircraft industry,most of which are used in transmissions and engines.The function of the helical gear is rich,can make the power to any direction conduction,can also change the speed and torque instantaneously,it can be said that if there is no helical gear,there will not be the development of the current automobile aircraft industry.

Helical gear has the following advantages:

1.The mesh surface from small to large to small, smooth mesh, small impact noise.

2.The carrying capacity is large, can improve the life and stability

3.Not easy to cut small volume.

4.The axial thrust is relatively large

In the automotive and aircraft industry, helical gears are widely used in mechanical components such as engines and transmissions, which can increase the mesh effect and make the transmission more stable. In terms of mechanical industry characteristics,the working mode between precision spur gears is an infinite cycle of sudden loading and sudden exit, or they do not engage,and once engaged, they release a lot of torque. The helical gear is tilted because the teeth are tilted, the contact between each tooth is an indirect contact mode, the contact area is from point to surface, and the meshing torque is also from small to large. Precision helical gearboxes have a smaller impact when shifting more smoothly, and of course the noise is relatively low.
