Abstract
The utility model discloses a novel camshaft, which comprises a shaft body, a cam and two cylindrical pins, wherein the shaft body is provided with a groove; the shaft body is provided with two positioning pin holes which are parallel to each other and pass through the groove transversely; the cam is also provided with two pin column holes which correspond to the positioning pin holes in the shaft body; and the cylindrical pins are inserted into the positioning pin holes and the pin column holes. Preferably, the positioning pin holes, the pin column holes and the cylindrical pins are the same in diameters. Preferably, the cylindrical pins are made of stainless steel. The novel camshaft has the beneficial effects that the novel camshaft is easy to process; and the cylindrical pins are used for clamping and connecting the cam with the shaft body tightly, so that the cam and the shaft body are connected more firmly, and the service life is further prolonged.
Description
Technical field
The utility model belongs to camshaft, particularly the camshaft on motor car engine.
Background technique
The camshaft of conventional engines adopts cam welding axis body, and stressed also very large because the cam work amount is large, the object of welding is difficult to reach requirement working life, and welding technique requires also very high.
