[0032] The embodiments of the present application will be described below with reference to the accompanying drawings.

[0033] A idler, as shown in Figure 1 and Figure 2 , comprises a bearing 1, a head section body 2, a compensation washer 3, a middle section body 4 and a tail section body 5, the head section body 2 and the middle section body 4 are connected through threads, one or more compensation washers 3 are placed between the head section body 2 and the middle section body 4, and similarly, the middle section body 4 and the tail section body 5 are connected through threads, the number of compensation washers 3 between them can be adjusted as needed, a plurality of middle section bodies 4 can be assembled between the head section body 2 and the tail section body 5, two middle section bodies 4 are connected through threads, and compensation washers 3 are also placed between the two connected middle section bodies 4, bearings 1 are arranged on the left side of the head section body 2 and the right side of the tail section body 5, and rib grooves 6 are formed in the middle of the head section body 2, the middle section body 4 and the tail section body 5.

[0034] When assembled, the middle section body 4 is connected to the head section body 2 through threads, a compensation washer 3 is placed in the middle, the tail section body 5 is connected to the middle section body 4 through threads, and a compensation washer 3 is placed in the middle, the number of compensation washers 3 is adjusted according to specific needs, and similarly, the number of middle section bodies 4 can be adjusted according to the width of the belt and the number of ribs, so that the length of the idler is consistent with the width of the belt, the number of rib grooves 6 of the idler is consistent with the number of ribs of the belt, and the fit is tight.

[0035] As shown in Figure 3 and Figure 4 , it further comprises an external thread 9 and an internal thread 10, the left side of the middle section body 4 and the tail section body 5 is provided with an external thread 9, the right side of the head section body 2 and the middle section body 4 is provided with an internal thread 10, and all external threads 9 and internal threads 10 can be matched and connected to each other, so that the section bodies can be conveniently and stably assembled and disassembled through the standardized thread connection mode.

[0036] As shown in Figure 3 and Figure 4As shown, it also includes a placement part 7 and an embedding part 8. The middle section 4 and the tail section 5 are each provided with a placement part 7 on the left side, and the head section 2 and the middle section 4 are each provided with an embedding part 8 on the right side. The placement part 7 is used to place the compensation washer 3, and multiple compensation washers 3 can be placed on it. The placement part 7 can be embedded into the embedding part 8. The size of the placement part 7 is exactly matched with the embedding part 8. The placement part 7 provides a fixed position for the compensation washer 3, allowing the compensation washer 3 to be stacked as needed. The embedding part 8 and the placement part 7 form a nested structure to ensure that the washer is accurately compressed when connected, avoid misalignment, and at the same time enhance the coaxiality and structural stability between the sections.

[0037] The bearing 1 is connected to the first end section 2 and the last end section 5 by an interference fit. The bearing 1 is locked by friction to prevent it from loosening or moving axially during operation, thereby improving the load-bearing capacity and long-term reliability of the idler wheel.

[0038] The outer diameters of the first segment 2, the middle segment 4, and the tail segment 5 are the same, which ensures consistent coaxiality during assembly. This helps reduce vibration and imbalance caused by differences in diameter between segments and improves the stability of the entire idler wheel structure.

[0039] The compensation washer 3 is annular, with its inner diameter being the same as that of the placement part 7, and its outer diameter being the same as that of the first end section 2, the middle section 4, and the tail end section 5, ensuring that the washer is flush with the surface of the section after installation, maintaining the overall consistency of the idler wheel's shape.

[0040] The lengths of the first segment 2, the middle segment 4, and the last segment 5 are equal, which helps to maintain the overall balance and stability of the idler wheel and makes it easy to flexibly adjust the total length of the idler wheel as needed.

[0041] The rib grooves 6 on the first end segment 2, the middle segment 4, and the tail end segment 5 are all located in the center of each segment, which allows for better adjustment of the spacing of the rib grooves 6 by the number of compensating washers 3.

[0042] The depth of the rib groove 6 is 1 / 3 to 1 / 2 of the section thickness, and its cross-sectional shape is trapezoidal to optimize the balance between structural stiffness and weight.
