BuA camshaft is a component of a piston engine. Its function is to control the opening and closing of the valve. Although the speed of the camshaft in the four-stroke engine is half of the crankshaft (the camshaft speed is the same as the crankshaft in the two-stroke engine), but usually its speed is still very high, and it needs to withstand a lot of torque, so the design of the camshaft in terms of strength and support requirements are very high, and its material is generally high-quality alloy steel or alloy steel. The design of camshaft plays a very important role in the design process of engine because the movement of valve is related to the power and operation characteristics of an engine. It can be manufactured by CNC engraving, sand casting, transparent acrylic(PMMA/PC) 3D Printing.
The position of the camshaft has three types: lower, middle and upper. The camshaft of the lower valve mechanism is located in the crankcase, the camshaft of the middle valve mech…
