[0029] This utility model discloses a novel camshaft for a 20-cylinder gas engine, according to the attached... Figures 1-2 As shown, it includes a journal 1 and a plurality of protrusions 2 mounted thereon and a sprocket 3, and a mounting assembly 4 is provided on one side of the journal 1.

[0030] like Figure 2 and Figure 4 As shown, installation component 4 includes:

[0031] The plug-in block 41 is clover-shaped and is fixedly connected to one end of the journal 1.

[0032] Positioning rod 42 is located below the insertion block 41 and is used for the installation and positioning of sprocket 3;

[0033] Fixed plate 43 is inserted into the end of the insertion block 41 and presses against the sprocket 3;

[0034] Locking bolt 44 is threadedly connected to plug block 41 and the head of locking bolt 44 presses against fixing plate 43.

[0035] According to the appendix Figures 1-2 As shown, the sprocket 3 has a plug hole 31 and a first through hole 32. The plug hole 31 can cooperate with the plug block 41, and the first through hole 32 can cooperate with the positioning rod 42.

[0036] According to the appendix Figures 1-3 As shown, a cylindrical groove 431 is provided on one side of the fixed plate 43, and a second through hole 432 is provided in the cylindrical groove 431. A plug-in groove 433 is provided on the other side of the fixed plate 43.

[0037] According to the appendix Figures 1-2 As shown, the positioning rod 42 is fixedly connected to the end of the journal 1, and the positioning rod 42 is inserted through the first through hole 32 and the second through hole 432. By using the positioning rod 42 to insert through the first through hole 32 on the sprocket 3 and the second through hole 432 on the fixed plate 43, precise positioning is provided for the installation of the sprocket 3, ensuring the coaxiality of the sprocket 3 and the journal 1, and avoiding engine vibration and noise problems caused by installation deviation.

[0038] According to the appendix Figures 1-3 As shown, the insertion slot 433 is inserted into the end of the insertion block 41.

[0039] According to the appendix Figures 1-2 As shown, the inner surface of the fixing plate 43, located on the outer periphery of the insertion groove 433, presses against the outer side of the sprocket 3. The fixing plate 43 is snapped onto the outer side of the sprocket 3 and is tightly connected to the insertion block 41 by the locking bolt 44, further enhancing the stability of the sprocket 3 installation and effectively preventing the sprocket 3 from loosening during engine operation.

[0040] According to the appendix Figures 1-2 As shown, the plug block 41 has a threaded hole 411, which is threadedly connected to the locking bolt 44.

[0041] According to the appendix Figures 1-2 As shown, the head of the locking bolt 44 abuts against the outer surface of the cylindrical groove 431 of the fixing plate 43.

[0042] Working principle: During installation, firstly, the sprocket 3 is engaged with the insert block 41, with the insert block 41 passing through the insert hole 31 on the sprocket 3. At this time, the positioning rod 42 is inserted into the first through hole 32 on the sprocket 3, providing initial positioning for the installation of the sprocket 3. Then, the fixing plate 43 is abutted against the end of the insert block 41, with the end of the insert block 41 inserted into the insert groove 433 on the fixing plate 43. Simultaneously, the positioning rod 42 passes through the second through hole 432 on the fixing plate 43, further ensuring the accurate position of the sprocket 3 and the fixing plate 43. At this time, the fixing plate 43 is engaged with the outside of the sprocket 3, serving to fix and support the sprocket 3. Finally, the locking bolt 44 is screwed into the threaded hole 411 on the insert block 41, so that the locking bolt 44 abuts against the fixing plate 43. By tightening the locking bolt 44, pressure is applied to the fixing plate 43, firmly fixing the fixing plate 43 to the insert block 41, thereby achieving a firm connection between the sprocket 3 and the journal 1.

[0043] During disassembly, loosen the locking bolt 44 to separate it from the fixed plate 43, relieving pressure on the fixed plate 43. Pull the fixed plate 43 out of the insert block 41, causing the end of the insert block 41 to disengage from the insert groove 433, while simultaneously pulling the positioning rod 42 out of the second through hole 432 and the first through hole 32. Remove the sprocket 3 from the insert block 41, completing the disassembly of the sprocket 3 from the journal 1.
