Description

Technical Field

[0001] The utility model relates to the technical field of gear train arrangement, in particular to a generator gear train arrangement. Background Art

[0002] An explosion-proof diesel engine is a diesel engine specially designed to work in explosive gas environments such as mines. It has explosion-proof performance to ensure that it will not ignite ambient gases when working in harsh environments. The working principle of a diesel engine is mainly to use the combustion of diesel in the cylinder to generate heat energy, which in turn drives the piston to move and converts heat energy into mechanical energy. In order to facilitate the layout of subsequent installation of components such as generators, the intake manifold and exhaust manifold are usually installed on both sides of the engine. When the diesel engine is started, diesel will burn to produce gases such as water vapor and carbon dioxide. These gases need to be discharged from the exhaust manifold, that is, the exhaust volume is greater than the intake volume. Therefore, the exhaust manifold is usually larger than the intake manifold, and the width of the exhaust manifold protrusion is also larger. Therefore, when the generator is installed on the engine, it is usually installed on one side of the exhaust manifold to reduce the protruding width of the engine.

[0003] Due to the large size of the generator, when the generator is installed on the diesel engine, it will still protrude part of the exhaust manifold. In order to prevent explosion, the explosion-proof diesel engine needs to be equipped with an intake flame arrester on the intake manifold, which makes one side of the intake manifold protrude more than the exhaust manifold. In addition, the protruding part of the generator makes the engine too wide and large in size, making it difficult to arrange and operate in narrow places such as underground mines.

[0014] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0015] according to Figure 1 The utility model provides a generator gear train arrangement, including: a crankshaft wheel 1, a tension wheel 2, a built-in water pump wheel 3, an external water pump wheel 4, a smooth idler wheel 5, a grooved idler wheel 6, a generator wheel 7, a fan wheel 8, and a multi-V belt 9.

[0016] The multi-V belt 9 is arranged on the side of the engine where the intake manifold is provided. The multi-V belt 9 sequentially passes around the crankshaft wheel 1, the tension wheel 2, the internal water pump wheel 3, the external water pump wheel 4, the grooved idler wheel 6, the generator wheel 7, the smooth idler wheel 5, the fan wheel 8, and finally returns to the initial position to complete the closing. These wheels are also arranged on the side of the multi-V belt 9 where the intake manifold is provided.

[0017] These wheels and the multi-V belt that drives them to rotate are arranged on one side of the intake manifold, so that the overall layout of the generator's wheel train is on the side of the intake manifold. Since the intake manifold is provided with a flame arrester, its protruding part is more than the exhaust manifold. When the generator wheel train is arranged on the side where the intake manifold is provided, the generator can make full use of the space on the side where the engine is provided with the intake manifold. The part protruding from the engine is smaller than when the generator is arranged on the side of the engine's exhaust manifold, which reduces the overall volume of the generator and the engine when they are connected, making it more convenient to operate in mines.

[0018] The smooth idler wheel 5 is arranged on the side of the grooved idler wheel 6 away from the intake manifold. The fan wheel 8 is arranged on the side of the smooth idler wheel 5 away from the intake manifold. The crankshaft wheel 1 is arranged on the side of the fan wheel 8 away from the intake manifold. The line connecting the external water pump wheel 4 and the smooth idler wheel 5 is perpendicular to the line connecting the grooved idler wheel 6 and the fan wheel 8. The external water pump wheel 4 is arranged on one side of the smooth idler wheel 5, and the generator wheel 7 is arranged on the other side of the smooth idler wheel 5. The internal water pump wheel 3 is arranged between the external water pump wheel 4 and the crankshaft wheel 1. The tensioning wheel 2 is arranged on the side of the internal water pump wheel 3 away from the smooth idler wheel 5. The multi-V belt 9 bypasses the internal water pump wheel 3 between bypassing the tensioning wheel 2 and the external water pump wheel 4. The wrap angles of the multi-V belt 9 and the crankshaft wheel 1, the tensioning wheel 2, the internal water pump wheel 3, the external water pump wheel 4, the smooth idler wheel 5, the grooved idler wheel 6, the generator wheel 7, and the fan wheel 8 are all greater than 120°.

[0019] In addition to the flame arrester, the explosion-proof diesel engine also needs to install an air filter on the intake manifold side, which makes the free space on the intake manifold side small. When the generator is installed, it may protrude from the bottom of the engine. The utility model uses a smooth idler wheel 5 and a grooved idler wheel 6. Through the above setting method, each structure is formed as follows Figure 1 The layout diagram shown in the figure makes the wrap angle of the multi-V belt 9 on each wheel greater than 120° to ensure that the friction between the multi-V belt 9 and each wheel is large enough so that the multi-V belt 9 can effectively transmit. When two idler wheels are not set, the multi-V belt cannot contact the fan wheel 8 after bypassing the generator wheel 7 and will be directly connected to the crankshaft wheel 1, making the fan wheel 8 unable to work. Therefore, some wheels need to be moved. The following is one example. It is necessary to move the fan wheel 8 and the generator wheel 7. When the fan wheel 8 moves, the direction is the direction in which the fan wheel 8 moves away from the external water pump wheel 4. When the generator wheel 7 moves, the direction is the direction in which the crankshaft wheel 1 approaches the external water pump wheel 4. If this method is used, the gear train of the generator will be arranged in a larger range, and it may protrude at the bottom, side, etc. of the generator, increasing the volume of the generator, making it difficult to operate in the mine. At the same time, a large range will be vacated in the middle of the generator gear train arrangement, and this part of the space cannot be used, resulting in waste. The utility model reduces the overall volume of the generator and fully utilizes the space by setting a smooth idler wheel 5 and a grooved idler wheel 6.

[0020] The surface of the smooth idler wheel 5 is smooth. The surface of the grooved idler wheel 6 is provided with grooves in the circumferential direction. The multi-V belt 9 corresponds to the grooves. The surface of the grooved idler wheel 6 is provided with grooves in the circumferential direction, and corresponds to the multi-V belt 9. The protrusions of the multi-V belt 9 correspond to the grooves, so that during the transmission process of the multi-V belt 9, it can better cooperate with the grooved idler wheel 6, so that the multi-V belt 9 is more appropriately tightened, and the transmission efficiency is improved. Figure 1 The smooth idler wheel 5 in the utility model has a larger wrap angle, while the smooth idler wheel 5 of the utility model has a smoother wrap surface, and the friction between it and the multi-V belt is smaller, thereby reducing the friction to prevent the belt from being subjected to excessive force at this point and causing breakage.

[0021] The working principle and use process of this utility model:

[0022] When it is necessary to install a distribution motor on an explosion-proof diesel engine, Figure 1 The arrangement relationship shown is set on the side of the engine with an intake manifold. When the generator needs to be used, the engine is started, and the engine drives the crankshaft wheel 1 to rotate, and the crankshaft wheel 1 drives the multi-V belt 9. When the multi-V belt 9 is driven, it drives the tensioner wheel 2, the internal water pump wheel 3, the external water pump wheel 4, the smooth idler wheel 5, the grooved idler wheel 6, the generator wheel 7, and the fan wheel 8 to rotate, so that each structure of the generator starts to work.

[0023] In addition, Figure 1 As shown, the internal water pump wheel 3 rotates differently than the external water pump wheel 4. On the one hand, it is for easy installation, and on the other hand, it can also be applied to different situations, such as when the water pump needs to rotate forward and reverse to achieve water inlet and outlet.

[0024] In summary, the utility model arranges the gear train of the generator on the side of the explosion-proof diesel engine with the intake manifold, so that the volume occupied by the generator and the explosion-proof diesel engine when they are connected can be reduced, which facilitates arrangement and operation in narrow places such as underground mines.
