Camshafts composed of steel pipe shaft body and several cam pieces assembled in different ways.
● Heated assembly
● Rolling assembly
● Hydraulic expansion assembly
● Liquid nitrogen cooling assembly
● Mechanical expansion assembly
● Welding assembly
Advantages of assembled camshafts:
1. The weight is lighter, with a weight reduction of 30% to 50%.
2. They can reduce emissions and improve overall performance.
3. The manufacturing cycle is shortened, and later technology optimization is more flexible.
YINGANG adopts rolling assembly and hydraulic expansion assembly.
