Abstract
In order to overcome the problem that the power of an engine can not stably reach designed power when the engine operates in a full load due to a crankshaft structure of a general power machine of the prior art, the utility model provides a crankshaft connecting rod journal structure of a general power machine. The crankshaft connecting rod journal structure of the general power machine comprises a flywheel end rod part, an output end rod part, a connecting rod journal and a crank throw shoulder, wherein the eccentric distance d between the connecting rod journal and the flywheel end rod part is 30 mm, and the eccentric distance d between the connecting rod journal and the flywheel end rod part is a distance between an axial line of the connecting rod journal and an axial line of the flywheel end rod part. The crankshaft connecting rod journal structure of the general power machine has the beneficial effect that the general power machine can stably reach the designed power when operating in a full load on the premise of no influence on the crankshaft strength.
Description
Technical field
The utility model relates to a kind of universal gasoline engine crankshaft, specially refers to a kind of general power machine crank shaft rod journal structure.
Background technique
Bent axle is one of most important part in general-purpose petrol engine (being commonly referred to general dynamic machine).Its function is that the straight reciprocating motion moment that piston and connecting rod are transmitted changes moment of rotation output into, to drive coupled power plant, in addition, also drives distribution device and the various annex of general dynamic machine itself.
Conventionally, general power machine crank shaft structure is made up of flywheel end bar portion, output terminal bar portion, rod journal and crank throw shoulder, the special-shaped part that flywheel end bar portion is connected with rod journal with output terminal bar portion is called as crank throw shoulder, and the part of rod journal and the common composition of crank throw shoulder is collectively referred to as crank throw.Wherein, the main link of flywheel end bar portion is engine flywheel, and crank throw is connected with connecting rod, the output terminal bar portion output engine power that is connected with outside.The throw of eccentric d of prior art general power machine crank shaft structure rod journal and flywheel end bar portion is generally 29 mm.The general power machine crank shaft structure of this kind of structure is in the time of oepration at full load, and engine power can not be stablized and reaches design power.The throw of eccentric d of described rod journal and flywheel end bar portion refers to the distance (flywheel end bar portion and output terminal bar portion are coaxial) of rod journal axis and flywheel end bar portion axis.Obviously, prior art general power machine crank shaft structure exists in the time of oepration at full load, and engine power can not be stablized the problem that reaches design power.
Summary of the invention
For overcome that prior art general power machine crank shaft structure exists when the oepration at full load, engine power can not be stablized the problem that reaches design power, the utility model proposes a kind of general power machine crank shaft rod journal structure.The utility model general power machine crank shaft rod journal structure, comprise flywheel end bar portion, output terminal bar portion, rod journal and crank throw shoulder, the throw of eccentric d of rod journal and flywheel end bar portion is 30 mm, and the throw of eccentric d of described rod journal and flywheel end bar portion refers to the distance of rod journal axis and flywheel end bar portion axis.
The useful technique effect of the utility model general power machine crank shaft rod journal structure is not affect under the prerequisite of crankshaft strength, makes general dynamic machine can stablize and reach design power in the time of oepration at full load.
Brief description of the drawings
Accompanying drawing 1 is the schematic diagram of the utility model general power machine crank shaft rod journal structure.
Below in conjunction with drawings and the specific embodiments, the utility model general power machine crank shaft rod journal structure is described further.
Embodiment
Accompanying drawing 1 is the schematic diagram of the utility model general power machine crank shaft rod journal structure, and in figure, 1 is flywheel end bar portion, and 2 is rod journal, and 3 is output terminal bar portion, and d is the throw of eccentric of rod journal and flywheel end bar portion.As seen from the figure, the utility model general power machine crank shaft rod journal structure, comprise flywheel end bar portion, output terminal bar portion, rod journal and crank throw shoulder, the throw of eccentric d of rod journal and flywheel end bar portion is 30 mm, and the throw of eccentric d of described rod journal and flywheel end bar portion refers to the distance of rod journal axis and flywheel end bar portion axis.Owing to having increased the throw of eccentric d of rod journal and flywheel end bar portion, be increased to 30mm from original 29mm, the outputting power of bent axle is increased to some extent, do not affecting under the prerequisite of crankshaft strength, make general dynamic machine can stablize and reach design power in the time of oepration at full load.
Obviously, the useful technique effect of the utility model general power machine crank shaft rod journal structure is not affect under the prerequisite of crankshaft strength, makes general dynamic machine can stablize and reach design power in the time of oepration at full load.
