Further, along the oil guide slot offered in the radial direction for being communicated with described asphalt channel and connnecting rod big end outer surface of big end hole on the both sides end face of described big end hole.
The utility model has following beneficial effect: the connecting rod with sufficient lubrication function of the present utility model, primarily of connecting rod small end, shaft and connnecting rod big end three part composition, described connecting rod small end is provided with little head bore, described connnecting rod big end is provided with big end hole, described connnecting rod big end separates, half is connecting rod cap, second half and shaft are integrated, described big end hole is formed after both make-ups connect, described shaft both sides are processed with groove along on shaft length direction, the section of shaft is made to be I-shaped, described connnecting rod big end offers the first oilhole being communicated with big end hole circumferential surface and groove inner side surface.The connecting rod with sufficient lubrication function of the present utility model passes through on described connnecting rod big end, offer the first oilhole being communicated with big end hole circumferential surface and groove inner side surface, lubricant oil is entered in the first oilhole inflow big end hole contact in surface, and then solve the technical problem that lubrication is not in place and lubrication is insufficient adopting splash lubrication mode to cause to lubricate connecting rod.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is a kind of side structure schematic diagram that the utility model has sufficient lubrication function connecting rod;
Fig. 2 is the another kind of side structure schematic diagram that the utility model has sufficient lubrication function connecting rod.
Embodiment
Below with reference to accompanying drawing, the utility model is described in detail:
As shown in Figure 1: the connecting rod with sufficient lubrication function in the present embodiment, primarily of connecting rod small end 1, shaft 2 and connnecting rod big end 3 three part composition, described connecting rod small end 1 is provided with little head bore 1a, described connnecting rod big end 3 is provided with big end hole 3a, described connnecting rod big end 3 separates, half is connecting rod cap 3b, second half and shaft 2 are integrated, described big end hole 3a is formed after both make-ups connect, described shaft 2 both sides are processed with groove 2a along on shaft 2 length direction, the section of shaft 2 is made to be I-shaped, described connnecting rod big end 3 offers the first oilhole 2b being communicated with big end hole 3a circumferential surface and groove 2a inner side surface.Described groove 2a can play the effect of collecting oil droplet, sufficient lubricant oil can be had in the process of link motion to enter into the first oilhole 2b and flow in big end hole contact in surface, and then solve the technical problem that lubrication is not in place and lubrication is insufficient adopting splash lubrication mode to cause to lubricate connecting rod.
Preferably, as shown in Figure 2, the cross section of described groove 2a is trapezoidal, the aperture being opened in the first oilhole 2b on groove 2a inner side surface is positioned at the upper base side of trapezoidal groove 2a, what needs were illustrated is, described trapezoidal limit not necessarily straight line, also can be arc, the length of upper base side, described trapezoid cross section is identical with the aperture bore of the first oilhole 2b on groove 2a inner side surface, when groove 2a falls into oil droplet, oil droplet can be made to enter into the first oilhole 2b with certain pressure and impact force on the two waist inclined-planes of the high-speed motion lower trapezoid groove 2a of connecting rod, and then the friction bearing in big end hole 3a is lubricated more fully.
As the further improvement of technique scheme, described connecting rod cap 3b and shaft 2 have a junction plane 3c, the intersection of described junction plane 3c and described big end hole 3a circumferential surface processes oil guiding hole 3d, described oil guiding hole is the through grooves in the both sides of arc, preferably, aperture, the both sides edge chamfer of described big end hole 3a forms the asphalt channel 3e of annular.Along the oil guide slot 3f offered in the radial direction for being communicated with described asphalt channel 3e and connnecting rod big end 3 outer surface of big end hole 3a on the both sides end face of described big end hole 3a.In the present embodiment, described connecting rod cap 3b is also provided with one for evoking the sharp beam hanger 3g of oil droplet.During work, swash beam hanger 3g and splash on connecting rod by the lubricant oil of tank bottoms hook, lubricant oil enters into oil guiding hole 3d through oil guide slot 3f, asphalt channel 3e successively, makes big end hole bearing be able to sufficient lubrication.By processing oil guiding hole in the intersection of junction plane and described big end hole circumferential surface, make lubricant oil be entered into oil guiding hole fully to contact with the sliding bearing surface in big end hole or little head bore, and then solve the technical problem that lubrication is not in place and lubrication is insufficient adopting splash lubrication mode to cause to lubricate connecting rod.
As the further improvement of technique scheme, described connecting rod small end 1 top offers the second oilhole 1b being communicated with little head bore 1a circumferential surface, and preferably, the aperture being positioned at the second oilhole 1b on connecting rod small end 1 top is bell mouth shape.The aperture of the second oilhole 1b bell mouth shape can increase collecting area and oil-collecting amount, and then makes the bearing pin in connecting rod small end 1 also can be able to sufficient lubrication.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
