Therefore, the design adopts a swinging mode to solve the problem, circular motion is carried out on the gear, gravity is used as driving power for driving, the energy-saving and environment-friendly test device has the advantages that energy is saved, the torque force of the transmission part 7 is smaller under the driving of the gravity, the transmission mechanism 1 cannot be damaged, and the counterweight can be increased in a mode of adding standard weights even if the driving force is insufficient, so that more standard gravity is obtained, and the test accuracy is improved. The first gear 2 is connected with the bearing frame 5, the first gear 2 is fixed on the bearing frame 5, and the second gear 17 is meshed with the first gear 2, so that the limiting plate 3 is driven to do circular motion along the first gear 2, meanwhile, the second gear 17 drives the first chain wheel 18 to rotate, and the first chain wheel 18 drives the second chain 12 to rotate through the first chain 11; during testing, the heavier end of the limiting plate 3 is placed at a high position, the initial height value is measured and recorded, then the limiting plate 3 moves under the action of gravity, the sensor 6 is arranged right below the limiting plate 3, and the limiting plate 3 passes through the sensor 6 in the moving process so that the sensor 6 can receive signals; meanwhile, the sensor 6 is electrically connected with the timer, the timer starts timing, when the heavier end of the limiting plate 3 moves to the highest position for the first time, the sensor 6 records the distance, the timer stops timing, and the test time t is recorded at the moment.
In some embodiments of the present invention, the specific calculation principle is to derive the formula according to the law of conservation of energy: wherein the second gear 17 has a mass m1The mass of the first sprocket 18 is m2The second chain wheel 19 has mass m3The initial height value is L, and the height L from the first movement to the highest position1The power loss is P.
m＝m1+m2+m3；
mgL-mgL1＝Pt；
Simultaneously, the height L from the first movement to the highest position is determined according to an arc length formula and an initial height value L1And the arc length of the limiting plate 3 in the time period t is obtained, so that the power loss of the transmission structure in unit time can be obtained, and the driving force can be increased in a mode of increasing the balance weight according to different production field conditions. The energy consumption of an electric engine, a gasoline engine or a diesel engine is avoided, the problem of damage to a transmission structure of the test is solved, the environmental protection performance is improved, and the cost is reduced.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
