[0021] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "provided with", "connection" and the like should be broadly understood, for example, "connection" can be fixed connection, can also be detachable connection, or integral connection; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] Please refer to Figure 1 、 Figure 2 and Figure 3 , a camshaft gear pressing plate for an engine;

[0023] It comprises a pressing plate body 1 and a pressing block assembly, the pressing block assembly is installed on the front surface of the pressing plate body 1, the pressing block assembly is used for contacting with the camshaft gear, the pressing block assembly comprises a mounting shaft 8, a mounting shell 10, a pressing roller 11 and a connecting shaft 12, the mounting shaft 8 is installed on the front surface of the pressing plate body 1, the mounting shell 10 is installed on one end of the mounting shaft 8, the connecting shaft 12 is symmetrically installed on both ends of the pressing roller 11, and the pressing roller 11 is rotatably installed in the mounting shell 10 through the connecting shaft 12, and the other end of the mounting shaft 8 is provided with a threaded connection hole 9;

[0024] The pressing plate body 1 is used for limiting the gear, so that the gear is more stable during rotation. In order to reduce the contact between the pressing plate body 1 and the gear, the pressing block assembly is installed instead of the pressing plate body 1 to limit the gear. The pressing roller 11 in the pressing block assembly is rotatably connected with the connecting shaft 12 and is in contact with the surface of the gear. Since the pressing roller 11 is rotatably connected, when the gear rotates, friction is generated between the pressing roller 11 and the gear, so that the pressing roller 11 rotates to avoid friction with the gear, thereby reducing the noise generated by friction. Furthermore, the pressing plate body 1 directly limits the gear, and the through hole 3 provides space for the pressing plate body 1 to press on the gear.

[0025] Please refer to Figure 1 and Figure 4 , a camshaft gear pressing plate for an engine;

[0026] The front surface of the pressing plate body 1 is symmetrically provided with a mounting groove 4 connected with one end of the mounting shaft 8. The inside of the mounting groove 4 is provided with a threaded through hole 5 corresponding to a threaded connecting hole 9. The back surface of the pressing plate body 1 is symmetrically provided with a groove body 6 corresponding to the other end of the threaded through hole 5. The inside of the groove body 6 is rotatably provided with a mounting bolt 7 connected with the threaded through hole 5 and the threaded connecting hole 9. The outer side of the pressing plate body 1 is symmetrically provided with a mounting hole 2.

[0027] Since the pressing block assembly is installed on the front surface of the pressing plate body 1 through the mounting shaft 8, the mounting shaft 8 is inserted into the inside of the mounting groove 4, and the mounting bolt 7 is rotatably inserted into the threaded through hole 5 and the threaded connecting hole 9, so as to fix the mounting shaft 8 and the pressing block assembly on the front surface of the pressing plate body 1. When the pressing block assembly is damaged during use, the mounting bolt 7 can be disassembled, so that the pressing block assembly can be disassembled from the pressing plate body 1 through the mounting shaft 8, avoiding the replacement of the entire gear pressing plate. The gear pressing plate can be installed on the equipment through the mounting hole 2, and the installed mounting bolt 7 will not protrude due to the groove body 6.

[0028] The working principle is that the gear pressing plate is installed on the pressing equipment through the mounting hole 2, so that the pressing equipment drives the pressing plate to press the gear and prevent the gear from deviating. When the pressing plate is used, the pressing block assembly installed on the front surface is in contact with the outside of the gear to apply pressure to the gear. When the gear rotates, the pressing roller 11 in the pressing block assembly is rolled by friction, thereby reducing the friction between the pressing plate and the gear. Moreover, the pressing block assembly can be disassembled and replaced, so that the entire pressing plate does not need to be replaced when the pressing plate is damaged.

[0029] It is apparent for a person skilled in the art that the present application is not restricted to the details of the above exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application. Therefore, the embodiments should be considered as exemplary only, and not limiting, the scope of the present application being defined by the appended claims rather than the above description, and all changes coming within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims concerned.
