Abstract
The utility model discloses a high power medium-speed diesel connecting rod which is easy forging, has low price and is convenient dismounting, comprising a connecting rod body and a connecting rod lid which is parting cut into a top lid and a lower lid, the connecting rod body and the lower lid fixedly connected with each other by a binding bolt are a packaged structure, the top lid and the lower lid are fixedly connected with each other by a bolt, the parting cut surface of the top lid and the lower lid is vertical with the central axis of the connecting rod body. The connecting rod of the utility model satisfies the requirement of domestic forging and machining, manufacturing cost can be substantially reduced, the connecting rod also overcomes the caused damage of the binding bolt by the miscut force between the top lid and the lower lid when the original connecting rod is in application course, thereby effectively avoiding accidents occurring.
Description
Technical field
The utility model relates to employed connecting rod in the high-power medium speed diesel.
Background technique
At present, employed connecting rod in the high-power medium speed diesel, its structure as shown in Figure 1, be made up of connecting rod shank 1 and connecting rod cap, connecting rod shank 1 and connecting rod cap are the integral structure of solid forging, during use, its connecting rod cap cuts into loam cake 21 and lower cover 22, be connected by connecting bolt 23 between loam cake 21 and the lower cover 22, and the branch tangent plane of loam cake 21 and lower cover 22 is the tilting structure, that is: this minute tangent plane with the central axis of connecting rod shank 1 between become angle about 45 degree.The shortcoming of the connecting rod of above-mentioned conventional construction is: because single-piece connecting rod blank weight blanking reaches 350 kilograms, domestic manufacturer is subjected to the restriction of forging equipment ability, now not having a family to forge enterprise can be controlled at single-piece blank weight error in 650 grams, so this large link rod is also whole dependence on import at present, price is very expensive; In addition, because the branch tangent plane of loam cake 21 and lower cover 22 is the tilting structure, because factors such as narrow space, installation or removal are very inconvenient, and this tilting structure connects the pulling force that the crankshaft crank footpath influences connecting bolt 23 easily, cause connecting bolt 23 loosening, cause connecting bolt 23 fractures, have major accident hidden danger.
The model utility content
Technical problem to be solved in the utility model is: provide a kind of and can be convenient to forge, price is lower, the high-power medium speed diesel connecting rod of convenient disassembly.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: high-power medium speed diesel connecting rod, comprise: connecting rod shank and connecting rod cap, connecting rod cap cuts into loam cake and lower cover, connecting rod shank is a modular construction with lower cover: connecting rod shank is fixedlyed connected by connecting bolt with lower cover, loam cake and lower cover are bolted to connection, and the branch tangent plane of loam cake and lower cover and the central axis of connecting rod shank are perpendicular.
Between connecting rod shank and the lower cover, and loam cake and lower cover between be provided with the assembling and positioning pin.
The beneficial effects of the utility model are: connecting rod described in the utility model is designed to split formula structure with connecting rod shank and connecting rod cap, the processing of coming of connecting rod shank and connecting rod cap branch, satisfied the processing request of domestic forging equipment, make the production domesticization of high-powered medium-speed diesel engines connecting rod become possibility, greatly reduce the manufacture cost and the process-cycle of this connecting rod; Also have, this set-up mode perpendicular to the connecting rod shank central axis greatly facilitates the loading and unloading of upper and lower covers between the upper and lower cover, and has overcome original connecting rod because the damage that the power of cutting sth. askew that the tilting setting in use produces causes connecting bolt.In addition, because between connecting rod shank and the lower cover and be provided with the assembling and positioning pin between loam cake and the lower cover, further facilitated between connecting rod shank and the lower cover, the installing and locating between loam cake and the lower cover.

Among the figure: 1, connecting rod shank, 21, loam cake, 22, lower cover, 23, connecting bolt;
Fig. 2 is the main TV structure schematic representation of high-power medium speed diesel connecting rod described in the utility model;
Among the figure: 1, connecting rod shank, 11, connecting bolt, 12, the assembling and positioning pin, 21, loam cake, 22, lower cover, 23, the assembling and positioning pin, 24, tensile bolt, 25, the stretching nut.
Embodiment
As shown in Figure 2, high-power medium speed diesel connecting rod described in the utility model, comprise: connecting rod shank 1 and connecting rod cap, connecting rod cap cuts into loam cake 21 and lower cover 22, connecting rod shank 1 is a modular construction with lower cover 22, that is: connecting rod shank 1 is fixedlyed connected by connecting bolt 11 with lower cover 22, then fixedlys connected with stretching nut 25 by tensile bolt 24 between loam cake 21 and the lower cover 22, and the branch tangent plane of loam cake 21 and lower cover 22 and the central axis of connecting rod shank 1 are perpendicular.For the ease of installing and the location, between connecting rod shank 1 and the lower cover 22, reach between loam cake 21 and the lower cover 22 and be respectively arranged with fixed locating stud 12 and assembling and positioning pin 23.When actual fabrication, the quantity of connecting bolt 11 and tensile bolt 24 can be provided with several according to the size and the application of connecting rod.
Claims (2)
1. high-power medium speed diesel connecting rod, comprise: connecting rod shank and connecting rod cap, it is characterized in that: connecting rod cap cuts into loam cake and lower cover, connecting rod shank is a modular construction with lower cover: connecting rod shank is fixedlyed connected by connecting bolt with lower cover, loam cake and lower cover are bolted to connection, and the branch tangent plane of loam cake and lower cover and the central axis of connecting rod shank are perpendicular.
