Description

Technical Field

[0001] This utility model relates to the field of diesel engine technology, specifically to a quick-disassembly and maintenance generator diesel engine. Background Technology

[0002] Diesel generators are important power generation equipment, using diesel fuel to drive a generator. In practical use, diesel generators require regular maintenance, and their components are frequently disassembled and reassembled. However, some existing diesel generator components, such as the connection between the flywheel and the gear ring, typically use traditional connection methods such as bolts. The disassembly and reassembly process is complex, requires repeated adjustments to the position, is time-consuming, and may affect the stability of equipment operation due to problems such as loose bolts, making it difficult to meet the needs of rapid maintenance. Therefore, a rapid disassembly and maintenance mechanism for diesel generators is proposed. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick-disassembly and maintenance generator-diesel engine, comprising a flywheel body and a gear ring slidably connected to its surface, and further comprising:

[0005] Several fixing blocks are fixedly connected to the surface of the flywheel body. The inner cavity of the gear ring is provided with several sliding grooves that cooperate with the fixing blocks. The fixing blocks are slidably connected to the inside of the sliding grooves. The inside of the flywheel body is provided with an inner groove.

[0006] The connecting structure used to connect the flywheel body to the gear ring is located inside the flywheel body;

[0007] A fixing structure used to prevent the connection structure from loosening is set on the surface of the flywheel body.

[0008] Preferably, the connecting structure includes a first bevel gear rotatably connected inside the inner groove, a plurality of second bevel gears meshing on the surface of the first bevel gear, a screw fixedly connected inside the second bevel gear, the surface of the screw rotatably connected to the inside of the flywheel body, a limit pin threadedly connected to the surface of the screw, a plurality of limit holes for cooperating with the limit pins being opened in the inner cavity of the gear ring, and a transmission component being provided on the surface of the first bevel gear.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a quick-assembly and maintenance generator-diesel engine includes a flywheel body 1 and a gear ring 2 slidably connected to its surface. Several fixing blocks 3 are fixedly connected to the surface of the flywheel body 1. Several sliding grooves 4 that cooperate with the fixing blocks 3 are opened in the inner cavity of the gear ring 2. The fixing blocks 3 and the sliding grooves 4 are slidably connected internally. An inner groove 5 is opened inside the flywheel body 1. A connecting structure 6 for connecting the flywheel body 1 and the gear ring 2 is provided inside the flywheel body 1. The connecting structure 6 includes a first bevel gear 61 rotatably connected inside the inner groove 5. Several second bevel gears 61 mesh with the surface of the first bevel gear 61. 2. The size of the first bevel gear 61 is larger than that of the second bevel gear 62. The second bevel gear 62 is symmetrically arranged along the circumference of the flywheel body 1. This arrangement can drive multiple sets of limit pins 64 to move synchronously, so that the gear ring 2 is subjected to uniform force, reducing local wear and extending service life. The second bevel gear 62 is internally fixedly connected to a screw 63. The surface of the screw 63 is rotatably connected to the inside of the flywheel body 1. The surface of the screw 63 is threadedly connected to the limit pins 64. The inner cavity of the gear ring 2 is provided with several limit holes 65 that cooperate with the limit pins 64. The surface of the first bevel gear 61 is provided with a transmission component 66.

[0024] With the connection structure 6 in place, in the initial state, the limiting pin 64 is retracted inside the flywheel body 1, and the gear ring 2 is fitted onto the surface of the flywheel body 1 through the cooperation of the fixing block 3 and the sliding groove 4. Then, the operator drives the first bevel gear 61 to rotate through the transmission component 66. The first bevel gear 61 drives multiple second bevel gears 62 meshing with it to rotate synchronously, thereby driving the screw 63 to rotate. The screw 63 pushes the limiting pin 64 to move through the threaded transmission, so that it extends and inserts into the limiting hole 65 of the gear ring 2, thereby rigidly fixing the gear ring 2 to the flywheel body 1. The surface of the flywheel body 1 is provided with a fixing structure 7 to prevent the connection structure 6 from loosening.

[0025] The transmission assembly 66 includes a fixed post 661 fixedly connected to the top of the first bevel gear 61. A fixed plate 662 is fixedly connected to the surface of the fixed post 661. A guide groove 663 is provided on the surface of the flywheel body 1 to cooperate with the fixed post 661. The surface of the fixed post 661 is slidably connected to the guide groove 663. With the setting of the transmission assembly 66, the operator can hold or use a tool to rotate the fixed plate 662, which will drive the fixed post 661 to slide in the guide groove 663 and drive the first bevel gear 61 to rotate, thereby controlling the extension and retraction of the limit pin 64 and realizing the operation of the connection structure 6.

[0026] The fixing structure 7 includes a fixing cover 71 that is snapped onto the top of the flywheel body 1. The fixing cover 71 is arc-shaped and fits snugly against the top of the flywheel body 1. This arrangement ensures a tight contact between the fixing cover 71 and the top of the flywheel body 1, preventing gaps or loosening due to shape mismatch, thereby enhancing the installation stability of the fixing cover 71 and preventing it from falling off due to vibration during diesel engine operation. Limiting grooves 72 are provided on both the left and right sides of the bottom of the fixing cover 71 to cooperate with the fixing plate 662. Fixing bolts 74 are bolted to the surface of the fixing cover 71, and threaded grooves 73 are provided on the surface of the fixing plate 662 to cooperate with the fixing bolts 74. With the setting of the fixing structure 7, when the fixing plate 662 moves to the designated position, the fixing cover 71 can be snapped onto the top of the fixing plate 662. At this time, the fixing plate 662 is snapped into the limiting groove 72. Then, the fixing bolt 74 passes through the fixing cover 71 and is screwed into the threaded groove 73 of the fixing plate 662, rigidly connecting the fixing cover 71 and the fixing plate 662, completely locking the transmission component 66 of the connecting structure 6, preventing the first bevel gear 61, the second bevel gear 62 and the screw 63 from rotating accidentally and causing the limiting pin 64 to loosen. This can prevent external dust and oil from entering the connecting structure 6, and can also limit the accidental rotation of the fixing plate 662.

[0027] Working principle: The operator first aligns the inner cavity of the gear ring 2 with the surface of the flywheel body 1, aligning the groove 4 on the gear ring 2 with the fixing block 3 of the flywheel body 1. Then, the operator slides the gear ring 2 along the fixing block 3 until the gear ring 2 is in contact with the flywheel body 1. At this point, the fixing block 3 and the groove 4 are fully engaged, which can restrict the rotation of the gear ring 2. Then, the operator drives the first bevel gear 61 to rotate by sliding the fixing plate 662. The first bevel gear 61 drives multiple second bevel gears 62 that mesh with it to rotate synchronously, which in turn drives the screw 63 to rotate. The screw 63 pushes the limiting pin 64 to move through the threaded transmission, so that it extends and inserts into the limiting hole 65 of the gear ring 2, thereby rigidly fixing the gear ring 2 to the flywheel body 1. Next, the fixing cover 71 is fastened to the top of the flywheel body 1, so that the limiting groove 72 at the bottom of the fixing cover 71 is engaged with the fixing plate 662, which can restrict the accidental rotation of the fixing plate 662. Then, the fixing bolt 74 is screwed in, so that it passes through the fixing cover 71 and screws into the fixing plate. The fixing cover 71 is rigidly connected to the fixing plate 662 in the threaded groove 73 of the plate 662, completely locking the connection structure 6. This prevents the first bevel gear 61, the second bevel gear 62, and the screw 63 from loosening due to vibration. When the gear ring 2 needs maintenance or replacement, the operator can unscrew the fixing bolt 74, causing the fixing bolt 74 to disengage from the threaded groove 73 of the fixing plate 662, and remove the fixing cover 71. At this time, the limiting groove 72 separates from the fixing plate 662, releasing the lock on the transmission component 66. Then, the fixing plate 662 is rotated in the opposite direction, which drives the first bevel gear 61 to rotate in the opposite direction through the fixing column 661. This causes the second bevel gear 62 and the screw 63 to rotate in the opposite direction. The screw 63 drives the limiting pin 64 to retract into the flywheel body 1, thereby disengaging from the limiting hole 65 of the gear ring 2 and releasing the axial fixation. Finally, the gear ring 2 slides in the opposite direction along the fixing block 3, so that the groove 4 of the gear ring 2 separates from the fixing block 3. The gear ring 2 can then be removed from the flywheel body 1 for inspection or replacement.
