Embodiment
Below in conjunction with accompanying drawing, an embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.It will be appreciated that, mentioned in following mode of execution of the present utility model " on ", D score, " left side ", " right side ", " front " and " reverse side " all take the direction shown in each figure as benchmark, these words that are used for limiting direction are only for convenience of explanation, do not represent the restriction to the concrete technological scheme of the utility model.
Diesel engine connecting bar lining oil groove of the present utility model is simple and reasonable, makes lubricant film enter from the both sides end face between connecting rob bushing and wrist pin, has avoided getting out oil inlet hole and weakening connecting rod small end reliable transmission and safety coefficient at connecting rod small end.
As shown in Figure 1 to Figure 3, the concrete structure of this diesel engine connecting bar lining oil groove comprises: be communicated with the Circumferential oil groove 2, V-type oil groove 3 and the circular arc enlarging oil groove 4 that are opened in connecting rob bushing 1 inboard, wherein, Circumferential oil groove 2 is offered along the inner circumferential of connecting rob bushing 1, opening is left in lower end, for laying V-type oil groove 3.V-type oil groove 3 is two, be laid in respectively the two ends of Circumferential oil groove 2, in the middle of it, intersection is communicated with the two ends of Circumferential oil groove 2, and circular arc enlarging oil groove 4 is arranged on the two ends of V-type oil groove 3, as the wide-angle filler opening at V-type oil groove 3 two ends, introduces the lubricant oil splashed so far.Lubricant oil enters this diesel engine connecting bar lining oil groove from the circular arc enlarging oil groove 4 that is positioned at connecting rob bushing 1 both sides end face, be distributed to the connecting rob bushing inwall everywhere by V-type oil groove 3 and Circumferential oil groove 2 again, like this, avoided getting out oil inlet hole and weakening connecting rod small end reliable transmission and safety coefficient at connecting rod small end.
Wherein, the circular arc (do not form close ring) of Circumferential oil groove 2 for offering along the inner circumferential of connecting rob bushing 1, opening is left in lower end, for laying V-type oil groove 3.Circumferential oil groove 2 enters the lubricant oil of this diesel engine connecting bar lining oil groove through circular arc enlarging oil groove 4 and V-type oil groove 3 for reception, and the inboard to connecting rob bushing 1 is paved with the formation oil film by it, to lubricate connecting rob bushing 1 and wrist pin, improve the reliable transmission of the two.
V-type oil groove 3 is two, be laid in opposite directions the two ends of Circumferential oil groove 2, in the middle of it, intersection is communicated with the two ends of Circumferential oil groove 2, and V-type oil groove 3 is smoothly connected near the circular arc of lining side and circular arc enlarging oil groove 4, as the wide-angle filler opening at V-type oil groove 3 two ends, introduces the lubricant oil splashed so far.It is more even that the both sides that the V-type oil groove runs through connecting rob bushing 1 make to enter the oil film of this diesel engine connecting bar lining oil groove.In addition, two branches of V-type oil groove 3 extend to the upside of connecting rob bushing 1 respectively, increase by a larger margin the loaded area of connecting rob bushing, make its carrying more reliable.The v-angle of V-type oil groove 3 is 60 °～120 °.
