[0029] It should be noted here that the spring 7 facilitates the return movement of the piston plate 602 after the movement.

[0030] The bottom of the sensing tube 601 that contacts the outside of the mounting shell 103 is made of heat-conducting material;

[0036] Working principle: During the engine assembly process, the bearing body 104 is sequentially installed on each installation slot 102 and the installation shell 103. After the installation is completed, the crankshaft is positioned and installed in the installation slot 102 and supported by the bearing body 104.

At this time, the lubricating oil stored in the liquid storage tank 402 is transported to the inside of the mounting shell 103 through the mounting tube 401. Under the connecting effect of the connecting tube 301 and the connecting groove 302, part of the lubricating liquid is transported to the inside of the mounting groove 102. When the lubricating oil is consumed and the surface temperature of the bearing body 104 rises, the lubricating oil is automatically added to the inside of the mounting groove 102 and the mounting shell 103. Through the automatic addition of lubricating oil, the bearing bodies 104 at different positions can be adaptively adjusted and controlled according to their own temperatures during use, so as to avoid excessive temperature on the bearing body 104, and further facilitate the support and use of the crankshaft by the bearing body 104.
