Description
Technical field
The utility model belongs to field of mechanical technique, especially relates to a kind of crankshaft rod assembly.
Background technique
Connecting rod is the power-transmission system in reciprocating internal combustion engine.Connecting rod is that motor realizes work cycle, completes the major moving parts of transformation of energy.
Its large end of traditional connecting rod is demountable structure, is connecting rod tip taken apart when mounted, is set on rod journal, then is fixed, although connecting rod tip is detachably convenient to install, because the activity of connecting rod tip place is comparatively frequent, easily causes connection loosing.
The length of traditional connecting rod is certain, and be installed to by connecting rod after on rod journal, the length of connecting rod will be fixed, and if desired change the length of connecting rod, then need whole connecting rod to disassemble, and unloading process comparatively bothers.
Model utility content
The purpose of this utility model to solve the deficiencies in the prior art part, and provide a kind of adjustable link length, the crankshaft rod assembly of adjustment transitive relation.
The purpose of this utility model is solved by following technical proposal:
A kind of crankshaft rod assembly, is characterized in that: comprise bent axle and be located at the connecting rod on bent axle;
Described bent axle comprises rod journal, is provided with left crank arm on the left of described rod journal, is provided with left main journal on the left of left crank arm, is provided with right crank arm on the right side of described rod journal, is provided with right main journal on the right side of right crank arm;
Described connecting rod comprises large end, big-end bearing, the body of rod and small end; Described big-end bearing is set on rod journal, and described large end is set in outside big-end bearing, and described large end outer wall is provided with a projection, projection offers a mounting groove, and described projection sidewall has multiple tapped through hole; The described body of rod and one end are provided with one and the mounting blocks that matches of mounting groove, the position that described mounting blocks matches with tapped through hole has tapped blind hole, also include the bolt matched with tapped through hole, tapped blind hole, the described body of rod is fixedly connected with large end by bolt; The described body of rod the other end is provided with small end.
Further, rod journal described in the utility model and left crank arm are welded and fixed; Described rod journal and right crank arm are welded and fixed.
Further, small end described in the utility model and the body of rod one-body molded.
Further, tapped through hole diameter described in the utility model and tapped blind hole equal diameters.
Compared to the prior art the utility model has following characteristics and beneficial effect:
1, rod journal and left crank arm are welded and fixed, and rod journal and right crank arm are welded and fixed, and connecting rod tip is integral type structure, add overall fastness.
2, between the body of rod of connecting rod and large end for removably connecting, if desired change the length of the body of rod, only the body of rod need be disassembled between large end, replace with the body of rod of other required sizes, Renewal process is simpler.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model body of rod and large end joint structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, a kind of crankshaft rod assembly, the connecting rod 2 comprising bent axle 1 and be located on bent axle 1.
Described bent axle 1 comprises rod journal 3, is provided with left crank arm 4 on the left of described rod journal 3, is provided with left main journal 5 on the left of left crank arm 4, is provided with right crank arm 6 on the right side of described rod journal 3, is provided with right main journal 7 on the right side of right crank arm 6.Described rod journal 3 and left crank arm 4 are welded and fixed; Described rod journal 3 and right crank arm 6 are welded and fixed.Left crank arm 4 and right crank arm 6 are all fixed on rod journal 3, and in operation process, left crank arm 4, relative movement can not occur between right crank arm 6 and rod journal 3, the soundness of crankshaft-link rod entirety is better.
As shown in Figure 2, described connecting rod 2 comprises large end 8, big-end bearing 9, the body of rod 10 and small end 11.Described big-end bearing 9 is set on rod journal 3, and described large end 8 is set in outside big-end bearing 9, and described large end 8 outer wall is provided with a projection 13, projection 13 offers a mounting groove 14, and described projection 13 sidewall has multiple tapped through hole 15.
The described body of rod 10 and one end are provided with one and the mounting blocks 16 that matches of mounting groove 14, the position that described mounting blocks 16 matches with tapped through hole 15 has tapped blind hole 17, also include the bolt 18 matched with tapped through hole 15, tapped blind hole 17, the described body of rod 10 is fixedly connected with large end 8 by bolt 18; The described body of rod 10 the other end is provided with small end 11, described small end 11 and the body of rod 10 one-body molded.
For removably connecting between the body of rod 10 of described connecting rod and large end 8, if desired change the length of the body of rod 10, only the body of rod 10 need be disassembled between large end 8, replace with the body of rod 10 of other required sizes, Renewal process is simpler.
