[0007] Further, the idler bracket includes a connecting plate and a flange.

It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by this application.

[0023] This embodiment provides an idler structure for a diesel engine water pump fan system, which can ensure the normal operation of other components without using a generator.

[0024] Referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 as shown, the idler structure of the system in this embodiment is as follows:

[0025] It includes a water pump, a water pump pulley 1, a generator bracket 3, a tensioner pulley 2, a fan bracket pulley 7, an idler bracket 4, and an idler 5 for replacing the original generator pulley.

[0026] Among them, the generator bracket 3 in the system is mainly used to install the original generator. In this structure, the generator is removed, and the generator bracket 3 is retained. The idler bracket 4 is installed on the generator bracket 3, and the idler 5 is installed on the idler bracket 4 so that the installation position of the idler 5 is the same as that of the original generator pulley. Finally, the water pump pulley 1, the tensioner pulley 2, the idler 5, and the fan bracket pulley 7 are connected by a belt 6 to achieve linkage.

[0027] In the above structure of this embodiment, the idler 5 replaces the original generator pulley to realize the support of the belt, which can eliminate the use of the generator as a support, thereby reducing the cost of the equipment and improving the reliability.

[0028] As a preferred solution of this embodiment, as shown in the accompanying drawings, the idler bracket 4 mainly includes a connecting plate 41, a flange 42, and a top block 43.

[0029] Among them, the connecting plate 41 is an integrally machined plate structure, and its front and rear surfaces are both machined into planes to ensure the installation accuracy of the idler 5. A first mounting hole 44 is provided on both sides of the connecting plate 41, and the idler bracket 4 is installed at the corresponding position of the generator bracket 3 through the first mounting hole 44. A positioning hole 45 is provided in the middle of the connecting plate 41, and the idler 5 is positioned by a bolt installed in the positioning hole 45. At the same time, three second connecting holes 46 are evenly distributed in the circumferential direction of the positioning hole 45. The second connecting holes 46 are countersunk holes, and the flange 42 is fixed to the connecting plate 41 through the second mounting holes 46.

[0030] The connecting plate 41 is mainly fixedly installed on the generator bracket 3 through two first mounting holes 44. Due to the special structure of the generator bracket 3, one end of the connecting plate 41 is directly in contact with the generator bracket 3 and fixed by bolts screwed into the first mounting holes 44. The other end of the connecting plate 41 is placed between the two legs of the generator bracket 3. Its front surface is in contact with one of the legs, and its rear surface is in contact with the surface of the other leg through the top block 43. The top block 43 is integrally cylindrical, and a through hole for the bolt to pass through is provided at the center of the top block 43. The top block 43, the connecting plate 41 and the generator bracket 3 are firmly connected together by bolts.

[0031] In the above structure of this embodiment, both the front and rear surfaces of the connecting plate 41 are flat planes, which can be conveniently processed by surface grinding, thereby improving the parallelism after installation, making the movement trajectories of the idler and other linkage parts the same straight line, and thus ensuring the reliable and stable operation of the equipment.
