Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of idler wheels and relates to a flat groove idler wheel. Background Art
[0002] An idler is a mechanical device that is mainly used to transfer power between two transmission gears that do not touch each other. Most existing idlers are integrated and need to be replaced as a whole when damaged, resulting in high replacement costs. At the same time, most of the idlers move by cooperating with bearings, but in actual use, when the bearing is damaged, it is relatively inconvenient to replace it. Even if it is seriously damaged, it also needs to be replaced as a whole, which does not meet the use requirements. Summary of the invention
[0003] The purpose of the utility model is to provide a kind of
[0004] The purpose of the utility model can be achieved through the following technical solutions: a flat groove idler, comprising an idler body with a connecting groove, characterized in that the idler body is provided with a movable unit connected to the connecting groove, which is convenient for connecting with its components and facilitating the movement of the idler body.
[0005] In the above-mentioned flat groove idler, the movable unit is composed of a bearing and a sleeve, and the sleeve is hollow. The bearing is arranged at the connecting groove in the idler body and slidingly cooperates with it. The bearing sleeve is arranged on the sleeve and connected with it. The end surface of the sleeve is provided with a plurality of threaded holes arranged along its circumferential direction.
[0006] In the above-mentioned flat groove idler wheel, both end faces of the idler wheel body located at the connecting groove are provided with limiting ring pieces connected thereto and used to limit the bearing position, and the limiting ring piece and the bearing connecting end are provided with limiting folded edges which are integrally provided therewith and used to enhance the limiting effect, and the two limiting ring pieces are connected to the idler wheel body by rivets.
[0007] In the above-mentioned flat groove idler wheel, the idler wheel body is provided with a combination ring connected to it at the connecting groove, which is used to reduce assembly wear and facilitate replacement. A spline groove is provided on the outer peripheral wall of the combination ring. A limit block connected to it and embedded in the combination ring is provided on the outer peripheral wall where the bearing and the combination ring are in contact. The combination ring is composed of two half rings spliced together.
[0008] Compared with the prior art, the flat groove idler has the following advantages:
[0009] 1. The idler main body is provided with a movable unit at the connection groove, which is connected to the idler main body and is convenient for connecting with its components and facilitating the movement of the idler main body. The above structure is arranged to facilitate its replacement and assembly. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the cross-sectional structure of the flat groove idler.
[0011] In the figure, 1, idler wheel body; 2, bearing; 3, bushing; 4, threaded hole; 5, limit ring; 6, limit folded edge; 7, combination ring; 8, limit block. DETAILED DESCRIPTION
[0012] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0013] like Figure 1 As shown, the flat groove idler comprises an idler body 1 with a connecting groove, and the idler body 1 is provided with a movable unit connected to the idler body 1 at the connecting groove, which is convenient for connecting with its components and facilitating the movement of the idler body 1, and the movable unit is composed of a bearing 2 and a sleeve 3, and the sleeve 3 is hollow, the bearing 2 is arranged at the connecting groove in the idler body 1 and is slidably matched with the idler body 1, and both ends of the bearing 2 extend out of the connecting groove respectively, the bearing 2 is sleeved on the sleeve 3 and connected with the idler body 1, and a plurality of threaded holes 4 arranged along the circumferential direction of the sleeve 3 are provided on the end surface of the sleeve 3, and the sleeve 3 is provided with a plurality of threaded holes 4 arranged along the circumferential direction thereof. There are two connection methods, one is connected to the input shaft or output shaft through the sleeve 3, and the other is connected to other components through studs. Both end faces of the idler main body 1 located at the connecting groove are provided with limit ring pieces 5 connected to it and used to limit the position of the bearing 2. The connection end of the limit ring piece 5 and the bearing 2 is provided with a limit folded edge 6 which is integrally provided with it and used to enhance the limiting effect. The two limit ring pieces 5 are connected to the idler main body 1 through rivets. Both end faces of the idler main body 1 are provided with limit protrusions which protrude axially outward and facilitate the installation of the limit ring piece 5.
[0014] To elaborate further, in order to facilitate assembly and reduce assembly wear, the idler body 1 is provided with a combination ring 7 connected to the idler body 1 at the connecting groove, which is used to reduce assembly wear and facilitate replacement. A spline groove is provided on the outer peripheral wall of the combination ring 7, and of course a spline can also be provided, and the idler body 1 is also required to have a corresponding structure at the connecting groove. The combination ring 7 is partially located in the limiting ring sheet 5, and a limiting block 8 connected to and embedded in the combination ring 7 is provided on the outer peripheral wall where the bearing 2 and the combination ring 7 are in contact. The combination ring 7 is composed of two half rings spliced together, and an assembly groove for installing the limiting block 8 is provided on the combination ring 7.
[0015] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0016] Although the terms such as idler wheel body 1, bearing 2, sleeve 3, threaded hole 4, limit ring piece 5, limit fold 6, combination ring 7, limit block 8 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
