Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine components, in particular to a diesel engine flywheel with the features of wear resistance and corrosion resistance. Background Art

[0002] In the actual application of diesel engines, flywheels play a key role, but traditional diesel engine flywheels often face many problems. On the one hand, if dust and impurities are adsorbed on their surface, these foreign objects will continue to rub against the surface as the flywheel rotates, causing increased wear and affecting the flywheel's performance and service life. In addition, there is a lack of internal protective components. After long-term use, the internal part lacks effective protection and is easily eroded by the external environment, resulting in corrosion and wear. On the other hand, for flywheels with protective accessories, it is often inconvenient to quickly replace the relevant protective components, which is not conducive to the optimization and maintenance of the overall performance.

[0003] The flywheel's smooth, beveled surface prevents dust from adhering and reduces wear. The counterweight system, through a specialized connection, enhances stability and allows for quick replacement of protective components, enhancing corrosion resistance. A replacement mechanism facilitates the replacement of worn rubber hoses, protecting the inner wall and reducing the risk of corrosion and wear. This comprehensively improves the flywheel's performance and ensures reliable diesel engine operation. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0017] Example: See Figure 1 - Figure 4 The utility model provides a technical solution: a wear-resistant and corrosion-resistant diesel engine flywheel, comprising: a flywheel disc 1, a connecting hole 3 is opened in the wall of the flywheel disc 1; a counterweight device 4, the outer wall of the counterweight device 4 is fixedly connected to the inner wall of the flywheel disc 1; a replacement device 5, the outer wall of the replacement device 5 is slidably connected to the inner wall of the flywheel disc 1; the counterweight device 4 includes a counterweight ring 41, a through hole 42 is opened in the wall of the counterweight ring 41, the inner wall of the counterweight ring 41 is slidably connected to a plastic frame 46 through a curved groove 43, and the curved groove 43 is opened in the wall of the counterweight ring 41, the outer wall of the plastic frame 46 is fixedly connected to a connecting plate 45, and the counterweight The inner wall of the ring 41 is connected to the outer wall of the connecting plate 45 through a limiting groove 44, and the limiting groove 44 is opened in the wall of the counterweight ring 41, a positioning hole 2 is opened in the wall of the flywheel disc 1, and a positioning groove 6 is opened in the wall of the flywheel disc 1. The flywheel disc 1 has a smooth surface and a bevel. When the flywheel rotates at high speed with the operation of the diesel engine, dust, impurities and other objects in the external environment will be difficult to adhere to it, effectively avoiding the wear problem that may be caused by dust accumulation, so that the surface of the flywheel disc 1 can maintain a good condition for a long time, reducing the hidden danger of surface damage due to friction of impurities, and thus ensuring the overall performance stability and service life of the flywheel.

[0018] The outer wall of the counterweight ring 41 is fixedly connected to the inner wall of the flywheel disc 1, the through hole 42 is connected to the positioning hole 2, the limiting groove 44 is connected to the curved groove 43, and the inner wall of the flywheel disc 1 is slidably connected to the outer wall of the plastic frame 46 through the positioning groove 6. The counterweight ring 41 is fixed in the inner wall of the flywheel disc 1, and the through hole 42 opened therein corresponds to the positioning hole 2 of the flywheel disc 1. When in use, a bolt is passed through the positioning hole 2 and the through hole 42, and then the bolt is fixed with a nut, thereby further increasing the stability of the connection between the flywheel disc 1 and the counterweight ring 41. The plastic frame 46 is placed in the inner wall of the counterweight ring 41 through the curved groove 43. During the sliding process of placing the plastic frame 46, due to the setting of the connecting plate 45, the side of the plastic frame 46 fixing the connecting plate 45 contracts and generates elastic force. When the connecting plate 45 corresponds to the limiting groove 44, the elastic force generated by the squeezing of the plastic frame 46 causes the connecting plate 45 to be accurately inserted into the limiting groove 44. This structure makes it convenient to replace the plastic frame 46 according to actual conditions.

[0019] The replacement device 5 includes a rubber tube 51, the outer wall of the rubber tube 51 is fixedly connected to a plug-in block 52, and the side of the rubber tube 51 away from the plug-in block 52 is fixedly connected to a positioning block 53. The two ends of the replacement device 5 are symmetrically provided with inclined grooves 54. The outer wall of the rubber tube 51 is slidably connected to the inner wall of the flywheel disc 1, the outer wall of the plug-in block 52 is plugged into the inner wall of the flywheel disc 1, and the outer wall of the positioning block 53 is plugged into the inner wall of the flywheel disc 1. During installation, the plug-in block 52 and the positioning block 53 are accurately plugged into the corresponding inner wall positions of the flywheel disc 1. The inclined grooves 54 at both ends facilitate identification of the position direction during the insertion operation. At the same time, after the replacement device 5 is installed, the inclined grooves 54 will form the same plane with the inclined surfaces on both sides of the flywheel disc 1, which is convenient for the staff to wipe the flywheel. In addition, during subsequent use, if the rubber tube 51 is worn and needs to be replaced, it can also be easily disassembled and replaced. The rubber tube 51 itself has certain elasticity and corrosion resistance, which can protect the inner wall of the flywheel disc 1 and reduce the risk of corrosion and wear caused by contact between internal components and the external environment.

[0020] Working principle:

[0021] The flywheel disc 1 serves as the main structure, and the connection holes 3 opened in its wall are used to connect with the crankshaft and other components of the diesel engine, so as to achieve assembly with the diesel engine and power transmission. The positioning holes 2 and positioning grooves 6 can provide accurate reference positions for the installation and positioning of other components, ensuring that each component is installed accurately and fits tightly. The flywheel disc 1 has a smooth surface and a bevel. When the flywheel rotates at high speed with the operation of the diesel engine, dust, impurities and other objects in the external environment will be difficult to adhere to it, effectively avoiding the wear problem that may be caused by dust accumulation, so that the surface of the flywheel disc 1 can remain in good condition for a long time, reducing the hidden danger of surface damage caused by friction of impurities, thereby ensuring the overall performance stability and service life of the flywheel. At the same time, each opening position on the flywheel disc 1 is closely matched with a bolt, a counterweight device 4 and a replacement device 5, thereby effectively blocking the opening. On the one hand, it prevents dust, water vapor, etc. from entering the flywheel through the opening, avoiding the adverse effects such as corrosion and pollution of internal components, ensuring that the internal components can work stably in a relatively clean and dry environment, and on the other hand, it also enhances the stability of the overall structure of the flywheel disc 1.

[0022] When in use, the counterweight device 4 works, the counterweight ring 41 is fixed in the inner wall of the flywheel disc 1, and the through hole 42 opened therein corresponds to the positioning hole 2 of the flywheel disc 1. When in use, a bolt is passed through the positioning hole 2 and the through hole 42, and then a nut is used to fix the bolt, thereby further increasing the stability of the connection between the flywheel disc 1 and the counterweight ring 41. The plastic frame 46 is placed in the inner wall of the counterweight ring 41 through the curved groove 43. During the sliding process of placing the plastic frame 46, due to the setting of the connecting plate 45, the side of the plastic frame 46 fixing the connecting plate 45 shrinks and generates elastic force. When the connecting plate 45 corresponds to the limiting groove 44, the elastic force generated by the squeezing of the plastic frame 46 makes the connecting plate 45 accurately inserted into the limiting groove 44. This structure makes it convenient to replace the plastic frame 46 according to actual conditions, thereby making it faster to replace the protective part at the opening position. Since the plastic material is relatively corrosion-resistant, it helps to improve the overall corrosion resistance of the flywheel.

[0023] The rubber tube 51 of the replacement device 5 can slide on the inner wall of the flywheel disc 1. During installation, the plug-in block 52 and the positioning block 53 are accurately inserted into the corresponding inner wall positions of the flywheel disc 1 respectively. The bevel grooves 54 at both ends facilitate identification of the position direction during the insertion operation. At the same time, after the replacement device 5 is installed, the bevel grooves 54 will form the same plane with the bevels on both sides of the flywheel disc 1, which is convenient for the staff to wipe the flywheel. In addition, during subsequent use, if the rubber tube 51 is worn and needs to be replaced, it can also be easily disassembled and replaced. The rubber tube 51 itself has certain elasticity and corrosion resistance, which can protect the inner wall of the flywheel disc 1 and reduce the risk of corrosion and wear caused by contact between internal components and the external environment. The large flywheel composed of these components in close cooperation has good wear and corrosion resistance while better meeting the diesel engine's requirements for the flywheel in power transmission, stable operation and other aspects, ensuring reliable operation of the diesel engine.
