[0026] Example 1, using Figure 1-Figure 8 A gasoline engine crankshaft with stable load-bearing and vibration-proof function according to one embodiment of the present invention is described as follows.

[0027] like Figure 1-Figure 2 As shown, a gasoline engine crankshaft with stable load-bearing and anti-vibration performance of the present invention comprises a gasoline engine housing 1, a top plate 2 is fixedly connected to the top of the gasoline engine housing 1, an ignition device 3 is fixedly connected to the bottom of the top plate 2, a dividing chamber plate 4 is evenly arranged on the inner wall of the gasoline engine housing 1, a main shaft 5 is arranged on the inner wall of the gasoline engine housing 1, an oil return thread block 6 is fixedly connected to one end of the main shaft 5, a placement flange 7 is fixedly connected to the end of the oil return thread block 6 away from the main shaft 5, a crankshaft front end 9 is fixedly connected to the end of the main shaft 5 away from the oil return thread block 6, and a connecting rod journal unit 8 is evenly arranged on the outer surface of the main shaft 5; When the present invention is working, the ignition device 3 will first compress the air in the gasoline engine housing 1. As the air enters and flows out of the gasoline engine housing 1, the connecting rod journal unit 8 will start working, thereby causing the main shaft 5 to rotate. During this process, the connecting rod journal unit 8 will autonomously reduce the vibration caused by the rotation and maintain a certain stability.

[0028] like Figure 3-Figure 4As shown, the connecting rod journal unit 8 includes a crank block 81, the outer surface of the crank block 81 is fixedly connected to a journal column 82, the end of the journal column 82 away from the crank block 81 is fixedly connected to a crank block 83, the outer surface of the journal column 82 is rotatably connected to a push frame 84, the top of the push frame 84 is fixedly connected to a piston 85, the inner wall of the crank block 81 is provided with a stabilizing mechanism 86, the outer surface of the crank block 81 is fixedly connected to a stabilizing block 87, the outer surface of the stabilizing block 87 is threadedly connected to a screw 88, the stabilizing block 87 is fixed to the crank block 81 by the screw 88, and the top of the crank block 81 is provided with a placement notch 89.

[0029] During the cycle of gas pressing the piston 85 to move downward and gas flowing out of the piston 85 to reset, the push rack 84 will drive the journal column 82, crank block 1 81 and crank block 2 83 to rotate, thereby driving the main shaft 5 to rotate.

[0030] By adding a stabilizing block 87 of a certain mass at a specific position on the outer surface of the crank block 1 81, when the piston 85 presses the push frame 84 and drives the crank block 1 81, the crank block 2 83 and the journal column 82 to rotate, the centrifugal force generated by the balancing block is opposite in direction and equal in magnitude to the unbalanced centrifugal force generated by the movement of the piston 85, the connecting rod and other components, thereby reducing vibration.

[0031] The outer surface of the crank block 1 81 is fixedly connected to the inner side of the main shaft 5 , and the side of the crank block 2 83 away from the journal column 82 is fixedly connected to the inner side of the main shaft 5 .

[0032] The specific workflow is as follows: The ignition device 3 will compress the air in the gasoline engine housing 1. As the air enters and flows out of the gasoline engine housing 1, the connecting rod journal unit 8 will start working. In the process of the gas pressing the piston 85 downward and the gas flowing out of the piston 85 to reset, the push rack 84 will drive the journal column 82, crank block 1 81 and crank block 2 83 to rotate, thereby driving the main shaft 5 to rotate. During the rotation process, the centrifugal force generated by the balance block is opposite to the unbalanced centrifugal force generated by the movement of the piston 85, connecting rod and other components, and is equal in magnitude, thereby reducing vibration.

[0033] Embodiment 2, use Figure 1-Figure 8 A gasoline engine crankshaft with stable load-bearing and vibration-proof function according to one embodiment of the present invention is described as follows.

[0034] like Figure 5-Figure 7As shown, a load-bearing, stable and vibration-proof gasoline engine crankshaft of the present invention is based on the first embodiment, and the stabilizing mechanism 86 includes a placement plate 861, a battery 862 is placed on the top of the placement plate 861, a telescopic spring 863 is fixedly connected to the inner wall of the placement plate 861, one end of the telescopic spring 863 is fixedly connected to a clamping block 864, a support rod 866 is fixedly connected to the inner wall of the crank block 81, one end of the support rod 866 is fixedly connected to a micro motor 867, the outer surface of the micro motor 867 is fixedly connected to a contact port 868, the output end of the micro motor 867 is fixedly connected to a transmission mechanism 865, and the end of the transmission mechanism 865 away from the micro motor 867 is fixedly connected to a buffer mechanism 869.

[0035] By placing the battery 862 in the placement notch 89, the elastic force of the telescopic spring 863 will push the clamping block 864 to fix the battery 862, and then the battery 862 will contact the contact port 868 of the micro motor 867, so that the micro motor 867 can further enhance the vibration reduction effect of the entire crankshaft through the transmission mechanism 865 and the buffer mechanism 869. The outer surface of the placement plate 861 is fixedly connected to the inner wall of the crank block 81.

[0036] The bottom of the battery 862 contacts the top of the placement plate 861 , and the side of the clamping block 864 away from the telescopic spring contacts the outer surface of the battery 862 .

[0037] like Figure 8 As shown, the transmission mechanism 865 includes a rotating shaft 8651, and the end of the rotating shaft 8651 away from the micro motor 867 is fixedly connected to a disc 8652, the outer surface of the disc 8652 is sleeved with a track 8653, the outer surface of the track 8653 is sleeved with a disc 8654, and the outer surface of the disc 8654 is fixedly connected to the rotating shaft 8655.

[0038] The micro motor 867 drives the shaft 1 8651 to rotate, and then drives the disk 1 8652 to rotate. The rotation of the track 8653 causes the disk 2 8654 to rotate and finally drives the shaft 2 8655 to rotate.

[0039] One end of the rotating shaft 1 8651 is fixedly connected to the output end of the micro motor 867 , and one end of the rotating shaft 2 8655 away from the disc 2 8654 is rotatably connected to the inner wall of the crank block 1 81 .

[0040] like Figure 8As shown, the buffer mechanism 869 includes a support plate 8691, the inner wall of the support plate 8691 is fixedly connected with a sliding rod 8692, the end of the support plate 8691 away from the transmission mechanism 865 is fixedly connected with a power supply plate 8695, the outer surface of the power supply plate 8695 is fixedly connected with an electromagnetic block 8696, the outer surface of the sliding rod 8692 is slidably connected with a gravity magnet 8694, and the outer surface of the gravity magnet 8694 is fixedly connected with a telescopic spring 8693.

[0041] As the rotating shaft 8655 drives the support plate 8691 to rotate, this rotation is limited and the rotation direction is opposite to the rotation direction of the main shaft 5. After rotating to the limit position, the transmission mechanism 865 will reset the support plate 8691 and rotate again. The rotation will generate traction and centrifugal force opposite to the main rotation of the overall crankshaft. At the same time, the power supply board 8695 can increase or decrease the input current to the electromagnetic block 8696 according to the rotation speed of the main shaft 5, thereby changing the magnetic force of the electromagnetic block 8696, and then changing the attraction of the electromagnetic block 8696 to the gravity magnet 8694, so that the position of the gravity magnet 8694 on the sliding rod 8692 changes, thereby changing the centrifugal force and traction of the three rotations of the support plate 8691, so that the force generated by the overall buffer and the force generated by the rotation of the main shaft 5 offset each other, and there will be no situation where one side is large and the other side is small, thereby further improving the shock absorbing effect.

[0042] The outer surface of the support plate 8691 is fixedly connected to one end of the second rotating shaft 8655 , and the side of the electromagnetic block 8696 away from the power supply board 8695 is fixedly connected to one end of the sliding rod 8692 .

[0043] The specific workflow is as follows: During operation, by placing the battery 862 in the placement notch 89, the elastic force of the telescopic spring 1 863 will push the clamping block 864 to fix the battery 862, and then the battery 862 will contact the contact port 868 of the micro motor 867. As the rotating shaft 2 8655 drives the support plate 8691 to rotate, the rotation will generate traction and centrifugal force opposite to the main rotation of the overall crankshaft. At the same time, the power supply board 8695 can increase or decrease the input current to the electromagnetic block 8696 according to the rotation speed of the main shaft 5, thereby changing the magnetic force of the electromagnetic block 8696, and then changing the attraction of the electromagnetic block 8696 to the gravity magnet block 8694, so that the position of the gravity magnet block 8694 on the sliding rod 8692 changes, thereby changing the centrifugal force and traction of the third rotation of the support plate 8691, so that the force generated by the overall buffer and the force generated by the rotation of the main shaft 5 offset each other, and there will be no situation where one side is larger and the other side is smaller.

[0044] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
