Description
Technical Field
The utility model belongs to camshaft processing field, concretely relates to concatenation formula camshaft.
Background
The camshaft is a component in a piston engine. Its function is to control the opening and closing action of the valve. Although the rotational speed of the camshaft is half of that of the crankshaft in a four-stroke engine (the rotational speed of the camshaft is the same as that of the crankshaft in a two-stroke engine), the rotational speed is still high and the camshaft is subjected to a large torque, so that the camshaft is required to be high in strength and support in design, and the camshaft is generally made of high-quality alloy steel or alloy steel. Because the valve motion law is related to the power and the running characteristics of an engine, the camshaft design occupies a very important position in the design process of the engine.
In the production of camshafts, camshafts with longer shaft lengths are required, and in the production of the camshafts, because the circumference is longer, the produced camshafts are easy to deform and have inconsistent axes, and further the produced camshafts are unqualified, so that the problem of scrapping is solved.
