Model utility content
Technical problem to be solved in the utility model is, provides a kind of assembled crankshaft, and its manufacturing is comparatively easy, and makes connecting rod neck that wearing and tearing be less likely to occur.
For solving the problems of the technologies described above, the assembled crankshaft that the utility model provides, it comprises multiple bent axle body, each bent axle body includes two main journals, two crankwebs and a connecting rod neck, main journal on all bent axle bodies is all coaxially set, all bent axle bodies are spaced along the axial direction of main journal, in two main journals on each bent axle body, one of them main journal is provided with an attachment hole, wherein another main journal is provided with a connecting head, being all connected with the interference fit of attachment hole by connecting head of arbitrary neighborhood two bent axle bodies;
Described connecting rod neck includes a central shaft and a metallic sheath, the two ends of central shaft are vertical with two crankwebs to be respectively connected, central shaft, two crankwebs and two one-body molded settings of main journal, metallic sheath activity is nested with on center shaft, the two ends of metallic sheath offset respectively at two crankwebs, metallic sheath are provided with the through hole for injecting lubricant oil to the gap between metallic sheath and central shaft.
As preferably, described through-bore axis all with the axis perpendicular of central shaft.
As preferably, described metallic sheath is made by No. 45 steel.
As preferably, on two main journals, equal fixed cover is equipped with an impeller.
After adopting above structure, the utility model compared with prior art, has following advantage:
When manufacturing assembled crankshaft of the present utility model, can first single bent axle body, bent axle body structure is comparatively simple, manufacture more for convenience, then bent axle body is connected with the interference fit of attachment hole by connecting head, namely complete the manufacture of assembled crankshaft of the present utility model, compared to bent axle made in one piece of the prior art, assembled crankshaft manufacturing of the present utility model is comparatively easy.
And, connecting rod neck comprises a central shaft and a metallic sheath, metallic sheath activity is nested with on center shaft, and lubricant oil can be injected by through hole to the gap between metallic sheath and central shaft, like this, assembled crankshaft of the present utility model operationally, metallic sheath can rotate, like this, suffered by the outer surface of metallic sheath is rolling friction, make the frictional force suffered by metallic sheath less, make metallic sheath that wearing and tearing be less likely to occur, and due to can lubricant oil be injected in the gap between metallic sheath and central shaft, make the frictional force between metallic sheath and central shaft less, make the frictional force between metallic sheath and central shaft very little.Like this, in use, wearing and tearing are less likely to occur connecting rod neck assembled crankshaft of the present utility model, make connecting rod neck be not easy distortion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, the utility model assembled crankshaft, it comprises multiple bent axle body, each bent axle body includes two main journals, 1, two crankwebs 2 and a connecting rod neck 3, in each bent axle body, the annexation of each parts is as follows: two crankwebs 2 are vertical with two main journals 1 to be respectively connected, connecting rod neck 3 is arranged between two crankwebs 2, and on the same line, the axis of connecting rod neck 3 parallels with the axis of main journal 1 axis of two main journals 1.
Main journal 1 on all bent axle bodies is all coaxially set, all bent axle bodies are spaced along the axial direction of main journal 1, in two main journals 1 on each bent axle body, one of them main journal 1 is provided with an attachment hole 101, wherein another main journal 1 is provided with a connecting head 102, being all connected by the interference fit of connecting head 102 with attachment hole 101 of arbitrary neighborhood two bent axle bodies.
Described connecting rod neck 3 includes central shaft 301 and a metallic sheath 302, the two ends of central shaft 301 are vertical with two crankwebs 2 to be respectively connected, central shaft 301, two crankwebs 2 and two one-body molded settings of main journal 1, metallic sheath 302 activity is nested with on central shaft 301, the two ends of metallic sheath 302 offset respectively at two crankwebs 2, metallic sheath 302 are provided with the through hole 3021 for injecting lubricant oil to the gap between metallic sheath 302 and central shaft 301.
When manufacturing assembled crankshaft of the present utility model, can first single bent axle body, bent axle body structure is comparatively simple, and each bent axle body structure is completely the same, manufacture more for convenience, then bent axle body is connected with the interference fit of attachment hole by connecting head, namely completes the manufacture of assembled crankshaft of the present utility model.
Assembled crankshaft of the present utility model operationally, metallic sheath 302 can rotate, make the frictional force suffered by metallic sheath 302 less, make metallic sheath 302 that wearing and tearing be less likely to occur, and due to can lubricant oil be injected in the gap between metallic sheath 302 and central shaft 301, make the frictional force between metallic sheath 302 and central shaft 301 less, make the frictional force between metallic sheath 302 and central shaft 301 very little.
