Description

Technical Field

[0002] The engine camshaft hole provides a position for installing and supporting the camshaft, ensuring that the camshaft can accurately control the opening and closing time of the valve, thereby realizing the normal intake, compression, power generation, and exhaust cycles of the engine. The dimensional accuracy and shape accuracy of the camshaft hole directly affect the installation accuracy and running smoothness of the camshaft. Usually, it needs to be precisely machined to ensure that parameters such as the hole diameter, cylindricity, and straightness meet strict technical standards, and it has good wear resistance: Since the camshaft rotates and rubs continuously in the hole, the camshaft hole needs to have good wear resistance. Generally, special materials or surface treatments such as quenching and carburizing are used to improve its hardness and wear resistance. Good lubrication conditions: In order to reduce the friction and wear between the camshaft and the hole, the camshaft hole is usually connected to the engine's lubrication system to ensure sufficient lubricating oil supply during operation.
