Abstract
A camshaft for machines relates to general gasoline engines, and comprises a shaft (1) with an exhaust cam (3) and an intake cam (4), and a transmission gear (2), wherein the shaft of the shaft (1) is sheathed with the transmission gear (2). Shafts between the shaft (1) and the transmission gear (2) are provided with a hole (5), a radial groove (6) is positioned between the shaft (1) and the transmission gear (2), and an annular groove (7) is positioned between the shaft (1) and the transmission gear (2). The shafts between the shaft and the transmission cam are of different shapes and structures in order to strengthen bonding force and the firmness of the transmission cam and the shaft made of enhancement engineering plastics. At the same time, the camshaft has characteristics of low noise during transmission, low processing cost, etc.
Description
One, technical field
The utility model relates to general gasoline engines, especially the camshaft of general gasoline engines.
Two, background technique
Deficiencys such as general gasoline engines (the be called for short logical machine) camshaft that uses is full steel structure, and other part processed complex of its metal, operation is many, cost is high, and the driving gear on the while cam shaft is that metallic material is made, and noise is big during transmission.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, adopts engineering plastics to make the logical machine camshaft of annexation between driving gear and the camshaft.
Technological scheme that the purpose of this utility model adopts is by being made up of axle, the driving gear of exhaust cam and intake cam on the axle, to be with driving gear on its axle.
The utility model, axle is gone up porose between described axle and the driving gear.
The utility model has radial groove on the axle between described axle and the driving gear.
The utility model has annular groove on the axle between described axle and the driving gear.
The utility model is having the difformity structure on the axle between axle and the driving gear, adhesive bond power, more firm between the driving gear made from the enhancement engineering plastics and the axle, characteristics such as noise is low during the while transmission, and processing cost is low.
Four, description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is embodiment's sectional structure of the utility model schematic representation;
Fig. 2 is another embodiment's sectional structure schematic representation of the utility model;
Fig. 3 is another embodiment's sectional structure schematic representation of the utility model.
Among the figure: the 6-radial groove 7-annular groove of 1-axle 2-driving gear 3-exhaust cam 4-intake cam 5-hole
Five, embodiment
As Fig. 1, Fig. 2, shown in Figure 3, by on the axle by the axle 1 of exhaust cam 3 and intake cam 4, driving gear 2 forms, is with driving gear 2 on its 1.Axle goes up porose 5 between described axle 1 and the driving gear 2.On the axle radial groove 6 is arranged between described axle 1 and the driving gear 2.On the axle annular groove 7 is arranged between described axle 1 and the driving gear 2.
The semi-finished product axle 1 of exhaust cam 3 and intake cam 4 and the driving gear 2 that engineering plastics are made are arranged on the axle, can adopt pressure injection technology to make, flow to the through hole 5 on the axle when making engineering plastics liquid, or radial groove 6, or annular groove 7, it is bonding between the two firm to make.
Claims (4)
1, a kind of logical machine camshaft is made up of axle (1), driving gear (2) that exhaust cam (3) and intake cam (4) are arranged on the axle, it is characterized in that being with driving gear (2) on axle (1) axle.
2, a kind of logical machine camshaft according to claim 1 is characterized in that axle is gone up porose (5) between described axle (1) and the driving gear (2).
3, a kind of logical machine camshaft according to claim 1 is characterized in that on the axle radial groove (6) being arranged between described axle (1) and the driving gear (2).
4, a kind of logical machine camshaft according to claim 1 is characterized in that on the axle annular groove (7) being arranged between described axle (1) and the driving gear (2).
