Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission structure technology and relates to an intermediate pulley with a V-groove. Background Technology
[0002] The intermediate pulley is the core component of the pulley structure. It is mainly used to connect the rim and the hub to form a complete pulley structure. In actual use, the V-groove plate and the bushing are usually fixedly connected by welding. Therefore, after long-term use, it needs to be replaced as a whole after wear, which leads to high replacement costs. At the same time, if the bushing is damaged, it will also need to be replaced as a whole, thus failing to meet the usage requirements. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing an intermediate pulley that reduces replacement costs.
[0004] The objective of this utility model can be achieved through the following technical solution: A V-groove intermediate pulley includes a pulley body, which includes a bushing and a web plate body connected to the bushing. The bushing has an annular groove on its outer peripheral wall at one end, which is arranged along its length and is used for mounting the web plate body. The bushing has several through holes spaced apart along its circumference on its inner peripheral wall at the web plate. These through holes extend axially outward and into the web plate body. The bushing has a sliding column in the through hole that slides with it and is used to limit the position of the web plate body.
[0005] In the aforementioned intermediate pulley with a V-groove, a convex ring portion that protrudes axially outward and is embedded in a bushing is provided on the left end face of the main body of the belt plate.
[0006] In the aforementioned intermediate pulley with a V-groove, a V-groove is formed on the outer peripheral wall of the main body of the bearing plate, and a V-groove is also formed on the outer peripheral wall of the bushing.
[0007] In the aforementioned intermediate pulley with a V-groove, several reinforcing ribs are provided on both ends of the main body of the web plate, which are spaced apart along their circumference, slide in cooperation with the bushings, and improve the structural strength of the main body of the web plate.
[0008] Compared with existing technologies, the intermediate pulley with V-groove can be disassembled by setting a sliding pin, thereby reducing replacement costs. Attached Figure Description
[0009] Figure 1 This is a cross-sectional structural diagram of the intermediate pulley with a V-groove.
[0010] In the diagram, 1 is the bushing; 2 is the main body of the web plate; 3 is the sliding column; 4 is the convex ring; and 5 is the reinforcing rib. Detailed Implementation
[0011] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0012] like Figure 1 As shown, this intermediate pulley with a V-groove includes a pulley body, which includes a bushing 1 and a web plate body 2 connected to the bushing 1. An annular groove is formed on the outer peripheral wall of one end of the bushing 1, extending along its length and for mounting the web plate body 2. This annular groove creates a stepped surface on the outer peripheral wall of the bushing 1 that abuts against the web plate body 2. Several through holes are spaced apart along the circumference on the inner peripheral wall of the bushing 1 at the web plate location. These through holes extend axially outward and into the web plate body 2. A sliding post 3 is provided within the through holes of the bushing 1, slidingly engaging with it and used to limit the position of the web plate body 2. When the sliding post 3 slides into the through hole, its inner end slides to the web plate body 2, thus engaging with it and serving to... The position of the main body 2 of the web plate is restricted, and the sliding column 3 is prevented from dislodging from the through hole by the assembly bearing. A convex ring 4 that protrudes outward axially and is embedded in the bushing 1 is provided on the left end face of the main body 2 of the web plate. Several guide strips connected to the convex ring 4 and serving as guides are provided on the convex ring 4. An annular groove for the convex ring 4 to be embedded and installed is provided on the stepped surface of the bushing 1. Several guide grooves connected to the annular groove and cooperating with the corresponding guide strips are also provided on the stepped surface of the bushing 1. A V-shaped groove is provided on the outer peripheral wall of the main body 2 of the web plate. A V-shaped groove is also provided on the outer peripheral wall of the bushing 1. Several reinforcing ribs 5 are provided on both ends of the main body 2 of the web plate at intervals along its circumference, which slide and cooperate with the bushing 1 and improve the structural strength of the main body 2 of the web plate.
[0013] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0014] Although this document uses terms such as "etc." extensively, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
