Product Description
OEM ODM Aluminum 20CrMoTi 40Cr Brass Stainless Steel Spur Gear
Gear transmission relies on the thrust between gear teeth to transmit motion and power, also known as meshing transmission. With this gradual meshing, helical gears operate much more smoothly and quietly than spur gears. Therefore, almost all automobile transmissions use helical gears.Since the teeth on the helical gear present a certain angle, the gears will be under a certain amount of stress when they mesh. Equipment using helical gears is equipped with bearings to withstand this pressure.
