Abstract
The invention relates to a crankshaft for an R180 internal combustion engine. The crankshaft comprises a left journal, a right journal and a balance block and is characterized in that the right journal comprises a first journal and a second journal, and the first journal is positioned at the right side of the second journal; the diameter of the first journal is less than the diameter of the second journal, and the first journal is in smooth transitional connection with the second journal through an inwardly concave arc surface; the inwardly concave radius of the inner concave arc surface is R1, and an outwardly convex arc surface connected with the inwardly concave arc surface is arranged on the second journal; the radius of the outwardly convex arc surface is R1.5. By adopting the technical scheme, the strength between the large and small journals can be improved, so that the journals cannot be broken, and the service life is prolonged; the journal is also convenient to process.
Description
Technical field
The present invention relates to a kind of I. C. engine crankshaft.
Background technique
The diameter of the transmission of power end of existing bent axle is less, and processing inconvenience between axle journal, the step between axle journal is generally skew lines and connects, and intensity is more fragile, and easily fractureed, working life is short.
Summary of the invention
Object of the present invention is just to provide a kind of R180 I. C. engine crankshaft, can improve the intensity between small one and large one two axle journal, prevents from being fractureed, increases the service life and have, and easy to process.
The present invention realizes by the following technical solutions: it comprises left axle journal, right axle journal and equilibrium block, it is characterized in that: right axle journal is made up of the first axle journal and the second axle journal, first axle journal is positioned at the right side of the second axle journal, the diameter of the first axle journal is less than the diameter of the second axle journal, first axle journal is connected by smooth excessiveness between inner concave arc surface with the second axle journal, the indent radius of inner concave arc surface is R1, the second axle journal is provided with the outer convex globoidal be connected with inner concave arc surface, and outer convex globoidal external convex radius is R1.5.
Owing to have employed technique scheme, the present invention can improve the intensity between small one and large one two axle journal, prevents from being fractureed, increases the service life and have, and easy to process.
Accompanying drawing explanation
Accompanying drawing of the present invention is described as follows.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged view of A in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, the present invention includes left axle journal 1, right axle journal 2 and equilibrium block 3, it is characterized in that: right axle journal 2 is made up of the first axle journal 2-1 and the second axle journal 2-2, first axle journal 2-1 is positioned at the right side of the second axle journal 2-2, the diameter of the first axle journal 2-1 is less than the diameter of the second axle journal 2-2, first axle journal 2-1 is connected by smooth excessiveness between inner concave arc surface 4 with the second axle journal 2-2, the indent radius of inner concave arc surface 4 is R1, second axle journal 2-2 is provided with the outer convex globoidal 5 be connected with inner concave arc surface 4, outer convex globoidal 5 external convex radius is R1.5.
The present invention adopts inner concave arc surface can increase join strength between the axle journal of two different-diameters, and radius is R1, makes it easy to process, and outer convex globoidal external convex radius is R1.5 also antisitic defect, improves intensity, easy to process.Owing to have employed technique scheme, the present invention can improve the intensity between small one and large one two axle journal, prevents from being fractureed, increases the service life and have, and easy to process.
