Abstract
The invention relates to a connecting rod of a two-stroke diesel engine with opposed pistons. One end of the connecting rod (5) is a small-end side while the other end per se is a big-end side; the small-end side is set into a fork structure with a U-shaped middle hollow part; the fork structure is internally provided with a rocker arm lower pin (6); a rocker arm (13) is mounted in the U-shaped structure through the rocker arm lower pin (6); and the big-end side is internally provided with a bearing bush (4) which is connected with a crank pin of a crankshaft. The connecting rod of the two-stroke diesel engine with the opposed pistons, disclosed by the invention, has the advantages of realizing the purpose of connecting the crankshaft with the rocker arm and realizing power output as the small end of the connecting rod adopts a U-shaped structural design with the hollow middle part, and the rocker arm is mounted in the U-shaped small end through the rocker arm lower pin, simplifying the connecting rod structure, strengthening coupling stiffness and lowering reciprocating inertial force.
Description
Technical field
The invention belongs to technical field of internal combustion engines, be specifically related to a kind of opposed pistons two stroke diesel engine connecting rod.
Background technique
Connecting rod is important spare part in the motor, is bearing the effect that the straight reciprocating motion of piston is converted to the crankshaft rotating motion.On the opposed two stroke diesel engine with rocker structure, cylinder lies in a horizontal plane in bent axle top certain distance and parallel with crankshaft level, requires lower link to have the effect that connects bent axle and rocking arm, and conventional linkage can't meet the demands.
Summary of the invention
Technical problem to be solved by this invention provides a kind of opposed pistons two stroke diesel engine connecting rod, and this connecting rod can connect bent axle and the rocking arm of opposed pistons two stroke diesel engine smoothly, has realized power output.
The technical solution used in the present invention is: a kind of opposed pistons two stroke diesel engine connecting rod, one end of this connecting rod 5 is microcephaly's side, the other end is the major part side, described microcephaly's side is arranged to the middle fork configuration of opening shelves of U-shaped, in its fork configuration, be provided with rocking arm downside pin 6; rocking arm 13 is installed in this U-shaped structure by rocking arm downside pin 6, is provided with bearing shell 4 in the described major part side, and bearing shell 4 is connected with the crank pin of bent axle.
Preferably, the middle fork configuration inboard of opening shelves of U-shaped of the present invention is provided with false boss.
Preferably, the outside of rocking arm downside pin 6 of the present invention has the groove of 3mm, and groove top, bottom all offer through hole, and bolt 9 passes that lower through-hole is connected with nut 8 on this.
Preferably, a side of U-shaped microcephaly side of the present invention is provided with bolt combination part 7, prevents that rocking arm downside pin 6 from rotating and skidding off.
The present invention compared with prior art has following beneficial effect: open the U-shaped structural design of shelves in the middle of this connecting rod small end adopts, rocking arm is installed in the middle of the U-shaped microcephaly by the rocking arm downside pin, has reached the purpose that connects bent axle and rocking arm, has realized power output; Bar linkage structure is simplified, strengthened coupling stiffness; Reduced reciprocal inertia force.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the plan view of microcephaly's side structure among Fig. 1;
Fig. 3 is most preferred embodiment figure of the present invention.
Reference character represents respectively: 1-connecting rod cap, 2-connecting-rod bolts, 3-setting sleeve, 4-bearing shell, 5-connecting rod, 6-rocking arm downside pin, 7-bolt combination part, 8-nut, 9-bolt, 10-piston, the upper connecting rod of 11-, 12-pitman arm shaft, 13-rocking arm, 14-bent axle, 15-flywheel.
Embodiment
As shown in Figure 1, 2, a kind of opposed pistons two stroke diesel engine connecting rod, it comprises: connecting rod cap 1, connecting-rod bolts 2, setting sleeve 3, bearing shell 4, connecting rod 5, rocking arm downside pin 6, bolt combination part 7, nut 8, bolt 9; One end of this connecting rod 5 is microcephaly's side, the other end is the major part side, described microcephaly's side is arranged to the middle fork configuration of opening shelves of U-shaped, be provided with false boss in this fork configuration inboard, in its fork configuration, be provided with simultaneously rocking arm downside pin 6; rocking arm 13 is installed in this U-shaped structure by rocking arm downside pin 6, and the outside of rocking arm downside pin 6 has the groove of 3mm, be convenient to rocking arm downside pin 6 and pack into and compress; Groove top, bottom all offer through hole, are used for construction bolt 9 and nut 8, compress rocking arm downside pin 6, and a side of U-shaped microcephaly side is provided with bolt combination part 7, prevent that rocking arm downside pin 6 from rotating and skidding off; Connecting rod 5 is connected with connecting rod cap by being connected by connecting-rod bolts 2 behind setting sleeve 3 location, and bearing shell 4 is housed in the major part side, is used for the connecting crank pin; Lubricated by the rocker arm oil holes fuel feeding between rocking arm downside pin 6 and the rocking arm 13, connnecting rod big end be by crank pin oilhole fuel feeding, on the connecting rod 5 without oil duct.
Working procedure of the present invention is as follows: when piston 10 arrives inner dead centre, fuel gas buring in the cylinder, pushing piston 10 outwards moves, connecting rod 11 motions in the drive, thereby drive rocking arm 13 and swing (pitman arm shaft 12 is fixed on the body) around pitman arm shaft 12, and then promoting connecting rod 5, connecting rod 5 is with again dynamic crankshaft 15 to rotate, thereby realizes power output.When piston 10 moved to the bottom dead-centre, under the drive of flywheel 16 and bent axle 15 inertial force, connecting rod 5 promoted rocking arm 13 and swings, and rocking arm 13 promotes again connecting rod 11, and upper connecting rod 11 pushing pistons 10 move to inner dead centre.
