[0017] Example: See Figure 1 - Figure 5 The utility model provides a technical solution: a flywheel device for a marine diesel engine, comprising: a connecting device 1, the connecting device 1 includes a flywheel disc 11, the outer wall of the flywheel disc 11 is plugged with a protective cover 3 through an installation groove 13, and the outer wall of the protective cover 3 is fixedly connected to the connecting ring 2 by bolts; the connecting device 1 also includes a limiting device 14, the outer wall of the flywheel disc 11 is slidably connected with a disassembly block 4 through a limiting groove 12, and the limiting groove 12 is opened in the wall of the flywheel disc 11, and the outer wall of the connecting ring 2 is fixedly connected to the outer wall of the flywheel disc 11 by bolts. After the assembly operation is performed, the protective cover 3 is plugged into the outer wall of the flywheel disc 11 through the installation groove 13, and then the connecting ring 2 is fixedly connected to the outer wall of the flywheel disc 11 by bolts, and then the protective cover 3 and the connecting ring 2 are further fixed by using the bolts. In this way, after being fixed in sequence from the inside to the outside, a flywheel is assembled, and the assembly structure facilitates the installation and transportation of the flywheel device.

[0018] The limiting device 14 includes a fixed block 141, a positioning through hole 142 is opened in the wall of the fixed block 141, the inner wall of the fixed block 141 is slidably connected to the pushing device 148 through a slide groove 143, and the slide groove 143 is opened in the wall of the fixed block 141, the outer wall of the fixed block 141 is slidably connected to the sliding block 144, the outer wall of the sliding block 144 is fixedly connected to the guide plate 145, the inner wall of the sliding block 144 is fixedly connected to the damping rod 146, the outer wall of the damping rod 146 is sleeved with a tension spring 147, the outer wall of the tension spring 147 is slidably connected to the outer wall of the sliding block 144, and the outer wall of the fixed block 141 is fixedly connected to the inner wall of the flywheel 11.

[0019] The pushing device 148 includes a sliding frame 1481, and support rods 1482 are fixedly connected to the two sides of the sliding frame 1481. The outer wall of the support rod 1482 is fixedly connected to the pushing ring 1483. A through hole 1484 is opened in the wall of the sliding frame 1481. The outer wall of the sliding frame 1481 is slidably connected to the inner wall of the fixed block 141 through the sliding groove 143. The outer wall of the pushing ring 1483 is slidably connected to the outer wall of the guide plate 145. When the protective cover 3 is installed, the raised sliding block 144 provides a limiting and positioning function. At this time, the position of the pushing ring 1483 needs to be adjusted and fixed, driving the sliding frame 1481 of the pushing device 148 to slide along the sliding groove 143 on the inner wall of the fixed block 141, driving the support rods 1482 on both sides. The push ring 1483 on the sliding frame 1481 moves. When the push ring 1483 moves to the position of pushing open the guide plates 145 on both sides, align the through holes 1484 in the wall of the sliding frame 1481 with the positioning holes 142 at the corresponding positions on the fixed block 141. Then use screws to pass through the through holes 1484 and the positioning holes 142 for fixing, so as to accurately fix the position of the push ring 1483. When the push ring 1483 is in the process of moving, it plays a guiding role in the process of moving the push ring 1483. At this time, the sliding block 144 can slide along the outer wall of the fixed block 141 and stretch the damping rod 146 and the tension spring 147. At this time, the sliding block 144 extends out of the flywheel disc 11, which can provide positioning and limiting for the installation of the protective cover 3.

[0020] Working principle:

[0021] When in use, the assembly operation is first performed, the protective cover 3 is inserted into the outer wall of the flywheel disc 11 through the installation groove 13, and then the connecting ring 2 is fixedly connected to the outer wall of the flywheel disc 11 by bolts, and then the protective cover 3 and the connecting ring 2 are further fixed with the bolts. In this way, the flywheel is assembled after being fixed from the inside to the outside. The assembled structure facilitates the installation and transportation of the flywheel device.

[0022] The limiting device 14 plays an important role in the actual assembly. The fixed block 141 is pre-fixed on the inner wall of the flywheel disc 11. When the protective cover 3 is installed, the raised sliding block 144 provides a limiting and positioning function. At this time, it is necessary to adjust and fix the position of the pushing ring 1483, drive the sliding frame 1481 of the pushing device 148 to slide along the sliding groove 143 on the inner wall of the fixed block 141, and drive the pushing ring 1483 on the support rods 1482 on both sides to move. When the pushing ring 1483 moves to the position of pushing the guide plates 145 on both sides, the through holes 1484 in the wall of the sliding frame 1481 are aligned with the corresponding positions on the fixed block 141. The positioning through hole 142 is aligned with the positioning through hole 142, and then a screw is used to pass through the through hole 1484 and the positioning through hole 142 to fix it, so as to accurately fix the position of the push ring 1483. When the push ring 1483 is in the process of moving, the push ring 1483 plays a guiding role in the movement process. At this time, the sliding block 144 can slide along the outer wall of the fixed block 141 and stretch the damping rod 146 and the tension spring 147. At this time, the sliding block 144 extends out of the flywheel disc 11, which can provide positioning and limit for the installation of the protective cover 3 and assist in fixing the bolts in the connecting ring 2. In this way, the design can flexibly adjust the state of the structure according to actual use requirements.

[0023] At the same time, the disassembly block 4 is slidably connected to the limiting groove 12 on the outer wall of the flywheel disc 11. When the flywheel needs to be disassembled and maintained in the future, the disassembly block 4 can assist the operation, facilitate the disassembly of the components, and increase or reduce the counterweight according to actual needs, to ensure the reliable operation of the entire flywheel device in the marine diesel engine, facilitate daily installation, adjustment and maintenance work, and improve the convenience of use and overall performance.
