1) Descriptions of Transmission Gear Shaft
Shaft parts made of high-strength alloy steel or special materials, both the transmission function of gears and shaft support.
2) Features of Transmission Gear Shaft
a) Wear resistance: Surface heat treatment (e.g. carburising and hardening) extends the life.
b) Fatigue resistance: Good material toughness to adapt to cyclical loads.
c) Lightweight: Titanium alloy or composite materials are used in some scenarios.
3) Working Principle of Transmission Gear Shaft
Power is transmitted using contact stresses on the gear tooth surfaces, and the material properties ensure stable long-term operation.
4) Application of Transmission Gear Shaft
Aerospace, automotive engines, heavy machinery and other high-load areas.
