Abstract
A kind of R180 I. C. engine crankshaft axle journal, comprise 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, the diameter of the first axle journal is less than the diameter of the second axle journal, at the first axle journal right-hand member, axis direction is provided with keyway, the top of keyway is positioned at the right-hand member end of the first axle journal, keyway tail end is near the second axle journal, and the tail end of keyway is arc, 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, and the length of keyway is longer, and transmission of power is reliable and stable.
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, processing inconvenience between axle journal, and the step between axle journal is generally skew lines and connects, intensity is more fragile, makes its intensity lower, is easily fractureed, working life is short, the less stable of singular association, affects the transmission of power.
Model utility content
The purpose of this utility model is just to provide a kind of R180 I. C. engine crankshaft axle journal, 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: comprise 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, the diameter of the first axle journal is less than the diameter of the second axle journal, at the first axle journal right-hand member, axis direction is provided with keyway, the top of keyway is positioned at the right-hand member end of the first axle journal, keyway tail end is near the second axle journal, and the tail end of keyway is arc, 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, and the length of keyway is longer, and transmission of power is reliable and stable.
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 Fig. 1, shown in 2, the utility model comprises right axle journal 1 and equilibrium block 2, it is characterized in that: right axle journal 1 is made up of the first axle journal 3 and the second axle journal 4, the diameter of the first axle journal 3 is less than the diameter of the second axle journal 4, at the first axle journal 3 right-hand member, axis direction is provided with keyway 5, the top of keyway 5 is positioned at the right-hand member end of the first axle journal 3, keyway 5 tail end is near the second axle journal 4, and the tail end of keyway 5 is arc, first axle 3 neck is connected by smooth excessiveness between inner concave arc surface 6 with the second axle journal, the indent radius of inner concave arc surface 6 is R1, second axle journal is provided with the outer convex globoidal 7 be connected with inner concave arc surface 6, outer convex globoidal external convex radius is R1.5.
The utility model employing inner concave arc surface can increase the 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.The length of keyway is longer, and length is about 46, and make its surface of contact large, transmission of power is reliable and stable.
