Description
Technical field
The utility model relates to a kind of measurement mechanism that is used to measure the unbalanced moments of general small-size gasoline engine balancing shaft.
Background technology
The effect of the balancing shaft of engine is the balance reciprocal inertia force.The unbalanced moments of balancing shaft has very big influence to the vibration of engine, if the unbalanced moments of balancing shaft is bigger than normal or less than normal, all can makes engine cause very big vibration and noise, and influence the life-span of engine.But at present for general small-size gasoline engine, the unbalanced moments of its balancing shaft all can't detect, thereby causes the unbalanced moments of balancing shaft uncontrollable.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of measurement mechanism of accurately measuring the unbalanced moments of general small-size gasoline engine balancing shaft rational in infrastructure, easy to use, quick.
The technical scheme that its technical matters that solves the utility model adopts is: comprise support, the arm beam of steelyard, scale base, main counterweight, sliding weight, register pin and balancing shaft; Two supports are the parallel, horizontal setting, and scale base is loaded on the arm beam of steelyard, and the axis place corresponding to scale base on the arm beam of steelyard offers axis hole, and the two axial ends of balancing shaft places respectively on the support of a side and in the above-mentioned axis hole, and the end of scale base places on the support of opposite side; The axis of balancing shaft is divided into long arm beam of steelyard A and the bar B two parts of giving short weight with the arm beam of steelyard, and the end of the bar B that gives short weight is connected with the gear of balancing shaft by register pin, and main counterweight is loaded on the end of long arm beam of steelyard A, and sliding weight is placed on the long arm beam of steelyard A slidably.When measuring the unbalanced moments of balancing shaft, at first select suitable relatively main counterweight to make the arm beam of steelyard near level, and then regulate sliding weight and on long arm beam of steelyard A, slide, make arm beam of steelyard level, at this moment: the barycenter of the barycenter of the barycenter of the quality of long arm beam of steelyard A * long arm beam of steelyard A to the barycenter of the quality * main counterweight of the vertical range+main counterweight of balancing shaft axis to the quality * sliding weight of the vertical range+sliding weight of balancing shaft axis to the barycenter of the quality * bar B that gives short weight of the vertical range-bar B that gives short weight of balancing shaft axis to the quality * register pin of the vertical range-register pin of balancing shaft axis is to the unbalanced moments of the vertical range=balancing shaft of balancing shaft axis.
For observing the horizontal situation of the arm beam of steelyard exactly, on the arm beam of steelyard, be provided with spirit bubble.
For ease of the unbalanced moments of calculated equilibrium axle, on the side face of long arm beam of steelyard A, be provided with metering scale.
The beneficial effects of the utility model are: it is rational in infrastructure, and is easy to operate, the quick unbalanced moments of accurately measuring the general small-size gasoline engine balancing shaft, for balancing shaft optimal design the reliable technique parameter is provided.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is that support, 2 is that balancing shaft, 2-1 are that gear, 3 is that register pin, 4 is that scale base, 5 is that the arm beam of steelyard, 6 is that sliding weight, 7 is that metering scale, 8 is that main counterweight, 9 is a spirit bubble.
