Abstract
The invention relates to an engine crankshaft and a piston rod. Structure forms of a crank arm of the crankshaft and the piston rod are changed so that the work efficiency of the engine is improved.
Description
Technical field: the present invention relates to engine art.
Background technique: because crankweb and the piston rod of available engine bent axle are straight-arm type and straight rod type substantially at present, defective just because of this structure, make when engine operation, the moment of cylinder detonation, piston rod, the crankweb of bent axle at this moment just point-blank, and the thrust direction of piston rod becomes vertical angle with the moving direction of check of crankshaft, this is the maximum drawback that said structure causes, though compole is short when above-mentioned, but still is unfavorable for conversion and the motor smooth operation that power is initial.
Summary of the invention: the objective of the invention is that the structure of crankweb by changing the available engine bent axle and piston rod finishes.
Description of drawings: legend shown in the Figure of description, just under the design principle all multi-form in two kinds of representative forms.Wherein accompanying drawing 1,2 is respectively the bent axle of curved crankweb and the bent axle of broken line type crankweb.Accompanying drawing 3,4 is respectively the piston rod on curved limit and the piston rod on broken line type limit.
Embodiment: the object of the present invention is achieved like this, the crank arm of new work engine bent axle and piston rod is designed to bent axle and the piston rod of the crankweb that is made of the identical crankweb of bending direction or flanging arm.Shown in Figure of description, the thrust that the cylinder detonation produces when engine operation by the crankweb of piston rod crankshaft, can be converted to the torsion of bent axle smoothly like this, thereby improves efficiency of engine, and the running of motor also can be more steady simultaneously.
Claims (2)
1. the bent axle of a new work engine is characterized in that: the crankweb of bent axle is by bent limit or flanging or tortuous limit even comprise that the straight flange combination in any forms, and crankweb integral body is to a lateral bending song.
2. the piston rod of a new work engine is characterized in that: the bar of piston rod is by bent limit or flanging or tortuous limit even comprise that the straight flange combination in any forms, and the bar integral body of connecting rod is to a lateral bending song.
