[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] The utility model provides a technical solution: Figure 1 - Figure 3As shown, in this embodiment, a shaft sleeve flywheel housing includes an outer shell 1, and three adjustment boxes 2 are fixedly connected to the outer surface of the outer shell 1. Clamping plates 3 are slidably provided inside the three adjustment boxes 2. Threaded holes 5 are opened on one side of the outer surfaces of the three adjustment boxes 2. The inner walls of the three threaded holes 5 are threadedly connected with tightening screws 4. One end of the three tightening screws 4 is in contact with the top surfaces of the three clamping plates 3 respectively. By buckling the outer shell 1 on the engine, and then rotating the three tightening screws 4 in sequence, the three clamping plates 3 are pushed to move in the process of the three tightening screws 4 entering the interior of the adjustment box 2, so that the three clamping plates 3 position the outer shell 1 and the engine, and then rotating the outer shell 1 so that the mounting screws 9 are aligned with the threaded holes on the engine, and then rotating the mounting screws 9 to install the outer shell 1 on the engine. After the fixation is completed, the three tightening screws 4 are rotated again to press the three clamping plates 3 against the engine surface, thereby realizing rapid positioning and fixing of the outer shell 1, convenient operation, and no additional tools are required for assistance, thereby improving installation efficiency, and the pressing of the three clamping plates 3 against the engine surface can make the outer shell 1 more firmly connected.

[0020] like Figure 2 and Figure 3 As shown, the inner walls of the three adjustment boxes 2 are provided with two slide grooves 6, and the two sides of the three clamping plates 3 are fixedly connected with guide sliders 7. The inner walls of the six slide grooves 6 are respectively slidably connected to the inner walls of the six guide sliders 7. Through the structural design of the slide grooves 6 and the guide sliders 7, the clamping plates 3 can be positioned, which can effectively prevent the clamping plates 3 from being deformed due to their own weight after the outer shell 1 is buckled on the engine, thereby improving the stability of the clamping plates 3.

[0021] like Figure 1 and Figure 2 As shown, a mounting hole 11 is opened through the middle of one side of the shell 1, and a shaft sleeve body 10 is installed inside the mounting hole 11. The outer surfaces of the shaft sleeve body 10 and the shell 1 are both provided with a galvanized layer. Through the structural design of the shaft sleeve body 10, the wear between the shaft and the shell 1 can be reduced.

[0022] like Figure 1 and Figure 2 As shown, a circular hole 8 is provided on the other side of the mounting hole 11 , and the structural design of the circular hole 8 allows for ventilation and heat dissipation.

[0023] like Figure 1 and Figure 2 As shown, multiple mounting screws 9 are threadedly connected on the outer surface of the housing 1 near the edge. Through the structural design of multiple mounting screws 9, the housing 1 can be fixed on the engine.

[0024] like Figure 2As shown, friction grooves 12 are provided on one side of the three clamping plates 3. By providing the friction grooves 12 on the clamping plates 3, the friction force of the clamping plates 3 after being pressed against the engine can be increased, further improving the stability of the connection between the housing 1 and the engine.

[0025] The utility model provides a shaft sleeve flywheel housing, and the specific working principle is as follows:

[0026] When installing the outer shell 1 on the engine, buckle the outer shell 1 on the engine, then turn the three tightening screws 4 in sequence, and push the three clamping plates 3 to move in the process of the three tightening screws 4 entering the interior of the adjustment box 2, so that the three clamping plates 3 position the outer shell 1 and the engine, then rotate the outer shell 1 so that the mounting screws 9 are aligned with the threaded holes on the engine, and then turn the mounting screws 9 to install the outer shell 1 on the engine. After the fixation is completed, turn the three tightening screws 4 again so that the three clamping plates 3 are pressed against the engine surface, and the installation is completed.
