Abstract
The utility model discloses a small connecting rod for a single-cylinder horizontal type diesel engine, which comprises a crankshaft connecting head (1), a piston connecting head (2), wherein the crankshaft connecting head (1) and the piston connecting head (2) are respectively connected with both ends of a rod body (3). A central through hole (4) which is used for sheathing a crankshaft is arranged on the crankshaft connecting head (1), and a central through hole (5) which is used for sheathing a piston pin is arranged on the piston connecting head (2). The utility model is characterized in that the distance L between the shaft core lines of the central through holes (4), (5) is 180 mm to 184.5 mm. The utility model has the advantages of light weight, little working vibration, material saving and low cost, and the service life is extended.
Description
Technical field
The utility model relates to a kind of diesel engine part, especially a kind of single-cylinder horizontal use for diesel engine small rod.
Background technique
Connecting rod is one of strength member in the diesel engine, and it is being born straight reciprocating motion is converted to the important function that rotatablely moves, and is stressed bigger in its working procedure.One end of connecting rod links to each other with piston, the other end links to each other with bent axle, link to each other by the body of rod between two ends, be processed with the less through hole of diameter that wrist pin is installed on the end that connecting rod links to each other with piston, be processed with the bigger through hole of diameter that links to each other with bent axle on the end that links to each other with bent axle, distance between the central axis of two through holes directly has influence on the overall dimensions of diesel engine, and the distance between the central axis on the connecting rod of existing diesel engine is generally bigger, maximum reaches 210 millimeters, whole layout and size have not only been influenced, and motion-affecting conversion efficiency, the inertia that produces in movement process of the weight of connecting rod itself makes it to be in for a long time under the bigger stress in addition, very easily fatigue damage has aggravated the vibration of complete machine, influences the stability of other parts work.
Summary of the invention
The purpose of this utility model is the oversize problem of connecting rod that exists at existing single-cylinder horizontal diesel engine, under the prerequisite that does not influence its service behaviour, designs a kind of closely spaced single-cylinder horizontal use for diesel engine small rod.
The technical solution of the utility model is:
A kind of single-cylinder horizontal use for diesel engine small rod, comprise bent axle connecting head 1, piston connecting head 2, bent axle connecting head 1 links to each other with two ends of the body of rod 3 respectively with piston connecting head 2, bent axle connecting head 1 is provided with the central through bore 4 of suit bent axle, piston connecting head 2 is provided with the central through bore 5 of piston set pin, it is characterized in that the distance L between the shaft axis of central through bore 4,5 is 180mm～184.5mm.
The beneficial effects of the utility model:
1, on the basis that does not change existing bar linkage structure, by reducing the distance between its central axis, make the size of shaft part shorten greatly, not only reduced the overall weight of connecting rod, thereby can make that its vibration is littler.
2, reduce the use amount of material, reduce manufacture cost.
3,, and, can improve the yield rate of its casting greatly along with the shortening of its size because shank portion is generally foundry goods.
4, because the shortening of shaft length correspondingly can reduce its suffered moment of torsion, thereby reduce its fatigue strength, make to be further enhanced its working life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1.
A kind of single-cylinder horizontal use for diesel engine small rod, comprise bent axle connecting head 1, piston connecting head 2, bent axle connecting head 1 links to each other with two ends of the body of rod 3 respectively with piston connecting head 2, bent axle connecting head 1 is provided with the central through bore 4 of suit bent axle, piston connecting head 2 is provided with the central through bore 5 of piston set pin, and the distance L between the shaft axis of central through bore 4,5 can be chosen arbitrarily between 180mm～184.5mm.
