Abstract
The utility model discloses a cam shaft for a junk head. The cam shaft for the junk head comprises a hollow shaft body and a cam arranged on the hollow shaft body. An oil outlet is arranged on the curved surface of the cam, the curved surface of the cam is further provided with an oil groove surrounding the curved surface of the cam, and the oil outlet is communicated with the oil groove. The cam shaft for the junk head with the oil groove arranged on the outer surface of the cam enables lubricating oil to flow circularly, prevents parts inside the junk head from causing breakdown due to friction overheating, and therefore prolongs the service life of the junk head.
Description
Technical field
The utility model relates to a kind of cylinder, is specifically related to the camshaft that a kind of cylinder head is used.
Background technique
The camshaft that existing a kind of cylinder head is used comprises hollow shaft and the cam that is arranged on the hollow shaft, be provided with oil outlet on the curved surface of cam, but the lubricant oil that uses can't spray enough amounts from this oil outlet, thereby cause producing larger heat energy because of friction between each component in the cylinder head, make each component produce easily fault, affect the working life of cylinder head.
The model utility content
The technical problem that (one) will solve
The technical problems to be solved in the utility model provides a kind of each component that can prevent because of the overheated fault that produces that rubs, and the camshaft used of the cylinder head that prolongs cylinder head working life.
(2) technological scheme
For solving the problems of the technologies described above, the camshaft that the utility model provides a kind of cylinder head to use, it comprises hollow shaft and the cam that is arranged on the hollow shaft, is provided with oil outlet on the curved surface of cam, also offer the oil groove around this cam curved surface on the curved surface of cam, oil outlet is connected with oil groove.
Wherein, this cam is one-body molded on hollow shaft.
(3) beneficial effect
Compared with prior art, the utility model is provided with oil groove at the outer surface of cam, makes lubricant oil capable of circulation mobile, prevents each interior component of cylinder head because of the overheated fault that produces that rubs, and then has prolonged the working life of cylinder head.
Description of drawings
Fig. 1 is the structural representation of the camshaft used of the utility model cylinder head.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but can not be used for limiting scope of the present utility model.
As shown in Figure 1, the camshaft that this cylinder head is used comprises hollow shaft 1 and the cam 2 that is arranged on the hollow shaft 1, be provided with oil outlet 4 on the curved surface of cam 2, also offer the oil groove 3 around these cam 2 curved surfaces on the curved surface of cam 2, oil outlet 4 is connected with oil groove 3.
Wherein, this cam is one-body molded on hollow shaft.
The utility model is provided with oil groove at the outer surface of cam, and oil groove is communicated with oil outlet, makes lubricant oil capable of circulation mobile, prevents each interior component of cylinder head because of the overheated fault that produces that rubs, and then has prolonged the working life of cylinder head.
It below only is preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
