Excavator Camshaft SK250-8 Engine Components VH135011610A
Construction Machinery Peculiarity 1. Material: camshafts are usually made of high-strength alloy steel to ensure sufficient strength, rigidity and durability. Sometimes, the surface of the camshaft will also undergo special treatment, such as hardening or coating, to improve its wear resistance and fatigue resistance. 2. CAM shape: The CAM shape on the camshaft directly affects the opening and closing time and lift of the valve. The specific CAM shape depends on the engine design and performance parameters, and can be optimized and adjusted according to needs. 3. CAM position: The CAM position on the camshaft determines the order and timing of the valve. Different arrangements (such as single camshaft, double camshaft, etc.) can meet different engine design requirements and performance requirements. 4. Transmission mode: The camshaft is usually connected with the crankshaft through the engine transmission system (such as belt, chain, etc.) to ensure the accurate rotation and smooth operation of the camshaft. 5. Rolling bearings: In order to reduce the friction loss of the camshaft and improve the rotational smoothness, the camshaft usually uses rolling bearings, such as roller bearings or sliding ball bearings. 6. Lubrication system: the camshaft needs to operate for a long time under high speed and high temperature conditions, so it needs to have a good lubrication mechanism. Engines are usually equipped with a corresponding lubrication system to ensure the lubrication and cooling of the camshaft and its associated components. 7. Heat treatment: The camshaft is usually subjected to heat treatment processes, such as quenching, tempering, etc., to improve its hardness and wear resistance.
