Description

Technical Field

[0001] The present application relates to the technical field of engine and supercharger connection, and in particular to an adapter structure of a low-explosion-resistant gas engine and a supercharger. Background Art

[0002] Detonation resistance refers to the ability of fuel or gas to resist detonation when burning in the engine, and is the main indicator of fuel or gas combustion performance. The engine supercharger is a device that increases the cylinder intake pressure. The air before entering the engine cylinder is first compressed by the supercharger to increase the air density, so that more air can be filled into the cylinder, thereby increasing the engine power. Nowadays, when a low-detonation-resistant gas engine is in operation, the supercharger is connected to the crankshaft pulley of the low-detonation-resistant gas engine through a belt. The inner blades of the supercharger are driven by the engine speed to generate pressurized air and send it to the engine's intake manifold, thereby increasing the engine's intake volume and improving the engine power.

[0003] In the related art, during the process of the crankshaft of the low-explosion-resistant gas engine driving the blade shaft of the supercharger to rotate through the transmission action of the pulley and the belt, the tension of the belt will gradually decrease or become loose due to long-term use. In order to ensure the effective transmission of the belt without slipping, the tension of the belt needs to be adjusted regularly. However, the conventional adjustment method usually requires manual operation to adjust the tension of the belt, which is cumbersome and troublesome, and the adjustment is not convenient enough. Therefore, we propose a adapter structure of a low-explosion-resistant gas engine and a supercharger to solve the above problems. Utility Model Content

The tension adjusting mechanism is used to adjust the tension of the belt 5 on the engine and is located between the crankshaft 1 and the blade shaft 2. The tension adjusting mechanism includes a mounting box 6, two slides 7, two rotating shafts 8, two tension adjusting wheels 9 and a driving assembly. The mounting box 6 is detachably fixedly mounted on the outer wall of the low explosion-proof gas engine and is located between the crankshaft 1 and the blade shaft 2, and the belt 5 is located in front of the mounting box 6. The two slides 7 are both slidably mounted in the mounting box 6. The two rotating shafts 8 are respectively rotatably mounted on the front side walls of the corresponding slides 7. The front ends of the two rotating shafts 8 extend outside the mounting box 6. The two tension adjusting wheels 9 are respectively fixedly mounted on the front ends of the corresponding rotating shafts 8. The belt 5 is located between the two tension adjusting wheels 9, and the two tension adjusting wheels 9 are fixedly mounted on the front ends of the corresponding rotating shafts 8. The wheels 9 are in rotational contact with the belt 5, and the driving assembly is arranged on the installation box 6. The driving assembly is used to adjust the spacing between the two tension adjustment wheels 9. The driving assembly includes two shaft seats 10, two screw rods 11, a motor 12, a driving shaft 13, an active bevel gear 14 and two driven bevel gears 15. The two shaft seats 10 are respectively fixedly mounted on the inner walls on both sides of the installation box 6, and the two screw rods 11 are respectively rotatably mounted on the corresponding shaft seats 10. The threaded rotation directions of the two screw rods 11 are set in the same direction. The two slide seats 7 are respectively threadedly sleeved on the corresponding screw rods 11. The motor 12 is fixedly mounted on the top of the installation box 6, and the driving shaft 13 is fixedly mounted on the output shaft end of the motor 12.

[0023] In this embodiment, the motor 12 is a commercially available forward and reverse motor. The wiring method and control method of the motor 12 are mature technologies in the art and are fully disclosed, so they will not be described in detail in this article.

[0024] In this embodiment, in order to ensure that the two rotating shafts 8 rotate smoothly without contacting the installation box 6, a rectangular avoidance hole 21 is opened on the front side wall of the installation box 6, and the front ends of the two rotating shafts 8 pass through the rectangular avoidance hole 21.

[0025] In this embodiment, in order to ensure that the two slides 7 can move horizontally and linearly in the installation box 6 smoothly, a transverse guide rod 16 located below the screw rod 11 is fixedly installed in the installation box 6, and the two slides 7 are slidably sleeved on the transverse guide rod 16.

[0026] In this embodiment, an air cooling component for blowing air to cool the belt 5 is provided on the installation box 6. The air cooling component includes an air cooler 17 and an air pipe 18. The air cooler 17 is fixedly installed on the outer wall of one side of the installation box 6, and the air pipe 18 is fixedly installed at the exhaust end of the air cooler 17. The end of the air pipe 18 away from the air cooler 17 extends into the installation box 6. By operating the air cooler 17, cold air can be generated and discharged into the installation box 6 through the air pipe 18, so that the cold air is discharged from the rectangular avoidance hole 21 and can be blown on the surface of the belt 5 to cool it, thereby avoiding overheating of the belt 5 and causing deterioration of elasticity and strength as well as transmission efficiency.

[0027] In this embodiment, the number of air-cooling components is set to two groups, and the two groups of air-cooling components are symmetrically distributed on the installation box 6. By setting two groups of air-cooling components, the efficiency of air-cooling the belt can be increased.

[0028] In this embodiment, two connecting ears 19 are fixedly installed on the top and bottom of the installation box 6, and bolt holes 20 are opened on the four connecting ears 19. Bolts can be used to fix the installation box 6 on the outer wall of the low explosion-resistant gas engine, thereby facilitating the disassembly and assembly of the installation box 6.

[0029] Through the above structure, the adapter structure of the low-explosion-resistant gas engine and the supercharger provided by the present application is used. During the process of the crankshaft 1 driving the blade shaft 2 to rotate through the belt transmission assembly, it is convenient to adjust the tension of the belt 5, which can effectively prevent the belt 5 from slipping during transmission. The operation is simple and convenient, saving time and effort, and the belt 5 can be air-cooled to avoid the overheating of the belt 5 causing the elasticity and strength to deteriorate and the transmission efficiency to deteriorate. During specific operation, when the low-explosion-resistant gas engine is running, the crankshaft 1 thereon drives the driving pulley 3 to rotate, and the transmission effect of the driving pulley 3, the driven pulley 4 and the belt 5 can be used to control the crankshaft 1 and the blade shaft 2 to rotate at the same time, that is, when the low-explosion-resistant gas engine is running, the supercharger also follows the operation;

[0030] When it is necessary to adjust the tension of the belt 5, by controlling the motor 12 to rotate forward, the motor 12 drives the driving shaft 13 and the active bevel gear 14 to rotate forward, and the active bevel gear 14 drives the two driven bevel gears 15 to rotate, so that the two slides 7 can drive the corresponding rotating shafts 8 and the tension adjusting wheel 9 to move in a direction close to each other, and the tension of the belt 5 during transmission increases. Similarly, by controlling the motor 12 to rotate reversely, the two slides 7 can drive the corresponding rotating shafts 8 and the tension adjusting wheel 9 to move in a direction away from each other, and the tension of the belt 5 during transmission decreases, thereby facilitating the adjustment of the tension of the belt 5, and effectively preventing the slippage of the belt 5 during transmission.

[0031] By starting one of the air coolers 17 for operation, cold air can be generated and discharged into the installation box 6 through the air supply pipe 18, so that the cold air is then discharged from the rectangular avoidance hole 21 and blown on the surface of the belt 5 for air cooling and cooling, thereby preventing the belt 5 from overheating and causing deterioration in elasticity and strength as well as deterioration in transmission efficiency. In addition, two air coolers 17 can be started and operated at the same time as needed to increase the amount of cold air discharged from the rectangular avoidance hole 21, that is, the amount of cold air blown on the surface of the belt 5 is larger, thereby improving the air cooling efficiency of the belt 5.
