Abstract
A kind of R180 I. C. engine crankshaft, comprise 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, and the first axle journal is connected by smooth excessiveness between inner concave arc surface with the second axle journal, and the indent radius of inner concave arc surface is R1, second axle journal is provided with the outer convex globoidal be connected with inner concave arc surface, outer convex globoidal external convex radius is R1.5.Owing to have employed technique scheme, the utility model 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.
Description
Technical field
The utility model 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.
Model utility content
The purpose of this utility model 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 utility model 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, second axle journal is provided with the outer convex globoidal be connected with inner concave arc surface, outer convex globoidal external convex radius is R1.5.
Owing to have employed technique scheme, the utility model 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 utility model is described as follows.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged view of A in Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 1, 2, the utility model comprises 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.
This can increase the join strength between the axle journal of two different-diameters with novel employing inner concave arc surface, 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 utility model 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.
