AI Technical Summary
The existing idler wheel bearings are severely worn in the limiting structure, leading to misalignment or reduced service life, which affects normal use.
An idler wheel with a V-groove was designed. By setting a limiting unit on the bushing, including an annular plate and balls, the bearing position is limited by the sliding of the balls in the annular groove. The inclined surfaces of the limiting ring and the abutment block enable convenient loading and unloading.
It effectively restricts the bearing position, reduces wear, extends service life, and ensures the normal operation of the idler wheel.

Abstract
Description
Technical Field
[0001] This utility model belongs to the field of transmission structure technology and relates to an idler wheel with a V-groove. Background Technology
[0002] An idler gear, also known as a bridge gear, is a gear that acts as a transmission mechanism between two non-contacting drive gears. The idler gear meshes with both gears simultaneously to change the rotation direction of the driven gear, making it the same as the driving gear. For this purpose, a bearing needs to be fitted onto a bushing to facilitate the normal operation of the idler gear. In actual assembly, since the bearing is externally mounted, a limiting structure is required to limit its movement. However, the contact between the limiting structure and the bearing inevitably causes wear. Over long-term use, this may lead to bearing misalignment or a reduction in service life, 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 existing technology by providing an idler wheel that solves these problems.
[0004] The objective of this utility model can be achieved through the following technical solution: an idler wheel with a V-groove, comprising a bushing, a bearing body sleeved on and connected to the bushing, and a first and a second flange disposed on the bushing, wherein the first flange is disposed on and connected to the bearing body, the bearing body comprising an outer ring, an inner ring, a cage, and steel balls, characterized in that a radially outwardly protruding convex ring portion is provided on the outer peripheral wall of the bushing and abuts against the bearing body, and a limiting unit connected to the bushing and used to limit the bearing position is provided, the limiting unit comprising an annular plate and a plurality of balls, and an annular groove for installing the balls is provided on the end face of the annular plate and the outer ring of the bearing body, thereby leaving a gap between the annular plate and the bearing body, and a disassembly unit connected to the bushing and used to limit the position of the annular plate and facilitate the loading and unloading of the annular plate.
[0005] In the aforementioned idler wheel with a V-groove, an annular pad with two end faces that respectively abut against the inner ring of the annular plate and the bearing body is fitted on the outer periphery of the bushing located between the annular plate and the bearing body.
[0006] In the aforementioned idler wheel with a V-groove, the disassembly and assembly unit includes a limiting ring connected to the bearing body. The outer peripheral wall of the limiting ring is provided with a plurality of eyelets arranged in the circumferential direction and connected to the limiting ring, and abutting blocks that abut against the annular plate. The abutting blocks are provided with inclined surfaces.
[0007] Compared with existing technologies, this idler wheel with V-groove is equipped with a limiting unit, which limits its movement without affecting the normal use of the bearing body. Attached Figure Description
[0008] Figure 1 This is a cross-sectional structural diagram of an idler wheel with a V-groove.
[0009] In the diagram, 1 is the bushing; 2 is the bearing body; 3 is the convex ring; 4 is the annular plate; 5 is the ball; 6 is the limiting ring; and 7 is the contact block. Detailed Implementation
[0010] 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.
[0011] like Figure 1 As shown, this idler wheel with a V-groove includes a bushing 1, a bearing body 2 sleeved on and connected to the bushing 1, and two flanges, a first flange and a second flange, mounted on the bushing 1. The first flange is mounted on and connected to the bearing body 2. The bearing body 2 includes an outer ring, an inner ring, a cage, and steel balls. A radially outwardly protruding ring 3 is provided on the outer peripheral wall of the bushing 1, which abuts against the bearing body 2. The ring 3 extends to the outer ring of the bearing body 2. A limiting unit connected to the bushing 1 and used to limit the bearing position is provided. The limiting unit consists of an annular plate 4 and several balls 5. Annular grooves for installing the balls 5 are provided on the corresponding end faces of the annular plate 4 and the outer ring of the bearing body 2. The balls 5 maintain a gap between the annular plate 4 and the bearing body 2. The ball bearing 5 can be embedded in the annular groove of the annular plate 4 or the annular groove of the outer ring, thereby preventing the assembled ball bearing 5 from detaching from the annular plate 4 or the outer ring. The ball bearing 5 can also be provided between the convex ring 3 and the inner ring. The bushing 1 is also provided with a disassembly and assembly unit that is connected to it and is used to limit the position of the annular plate 4 and facilitate the installation and removal of the annular plate 4. The bushing 1 is provided with an annular pad on its outer periphery between the annular plate 4 and the bearing body 2, with its two end faces respectively abutting against the annular plate 4 and the inner ring of the bearing body 2. The outer diameter of the annular pad is smaller than the inner diameter of the outer ring of the bearing body 2. The disassembly and assembly unit includes a limiting ring 6 connected to the bearing body 2. The outer peripheral wall of the limiting ring 6 is provided with a plurality of holes arranged in the circumferential direction and connected to it, and abutting against the annular plate 4. The abutting block 7 is provided with an inclined surface.
[0012] 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.
[0013] 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.
