Description

Technical Field

[0001] The utility model relates to a vibrating wheel rubber damper and a vibrating roller, belonging to the technical field of roller vibration reduction. Background Art

[0002] Currently, the rubber shock absorbers used on the vibratory wheels of vibratory rollers all adopt a structure in which metal parts and rubber are bonded together. The rubber body is usually cylindrical, and the bonding point with the metal part is transitioned through a rounded corner. The rubber body near the mounting hole for bolt connection of the metal part is cut with a straight edge to leave space for bolt fixing. During use, this structure is easily damaged by the rounded corner transition due to stress concentration, and the middle part of the straight edge of the rubber body near the mounting hole is easily cracked due to stress concentration. Summary of the Invention

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a vibrating wheel rubber damper and a vibrating roller, which can reduce stress concentration and extend service life.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts a vibration wheel rubber damper, comprising:

[0005] The metal piece includes a first metal piece and a second metal piece, wherein the first metal piece and the second metal piece are both provided with mounting holes;

[0006] The rubber body is in a concave spindle shape, with a cross section gradually increasing from the middle to both ends. The generatrix of the rubber body is a circular arc or an elliptical arc. One end of the rubber body is connected to the first metal part, and the other end is connected to the second metal part.

[0007] In some embodiments, the rubber body is provided with arc edges near the mounting holes of the first metal component and the second metal component.

[0008] In some embodiments, two ends of the rubber body are bonded to the first metal piece and the second metal piece respectively.

[0009] In some embodiments, the first metal member and the second metal member are respectively provided with 2-4 mounting holes.

[0010] In some embodiments, the first metal member is connected to the vibrating wheel via bolts, and the second metal member is connected to the roller frame via bolts.

[0011] In some embodiments, the diameter of the middle portion of the rubber body is 50 to 190 mm, and the diameters of the two ends of the rubber body connected to the metal member are 1.1 to 1.3 times the diameter of the middle portion.

[0012] The second aspect of the present invention provides a vibratory roller, on which the vibratory wheel rubber damper is installed.

[0013] Compared with the existing technology, the vibration wheel rubber shock absorber of the utility model is generally in the shape of an inward-concave spindle, and the cross-section gradually becomes larger from the middle to the two ends, thereby increasing the bonding area between the rubber body and the metal parts at both ends, while reducing stress and stress concentration, and improving the service life of the rubber shock absorber.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0021] like Figure 1 、 Figure 2 and Figure 3 As shown, a vibration wheel rubber damper includes a first metal member 1, a second metal member 2 and a rubber body 3;

[0022] The first metal member 1 and the second metal member 2 are both provided with mounting holes, the first metal member 1 is connected to the vibrating wheel, and the second metal member 2 is connected to the roller frame;

[0023] The rubber body 3 is in an inwardly concave spindle shape, and the cross-section of the rubber body 3 gradually increases from the middle to the two ends. The generatrix of the rubber body 3 is a circular arc or an elliptical arc 3-1. One end of the rubber body 3 is connected to the first metal part 1, and the other end is connected to the second metal part 2. When the roller is working, the elastic rubber body 3 can reduce the vibration between the vibrating wheel and the roller frame.

[0024] In some embodiments, as Figure 1 、 Figure 3 As shown, the rubber body 3 is provided with an arcuate edge 3-2 near the mounting holes of the first metal member 1 and the second metal member 2. This invention improves upon the traditional practice of cutting a straight edge into the rubber body to provide a bolt fixing space, by providing an arcuate edge 3-2 that matches the shape of the bolt. This increases the bonding area and creates a gradual change in the cross-section of the rubber body from the center of the mounting hole to the axis of rotation of the rubber body, reducing stress and stress concentration.

[0025] In some embodiments, both ends of the rubber body 3 are bonded to the first metal component 1 and the second metal component 2 respectively, thereby increasing the strength of the connection with other components and improving the service life.

[0026] In some embodiments, the first metal member 1 and the second metal member 2 are provided with 2-4 mounting holes respectively. Figure 1 、 Figure 3 As shown, the first metal member 1 is provided with two first mounting holes 1-1, and the second metal member 2 is provided with two second mounting holes 2-1. The angle between the line connecting the two first mounting holes 1-1 and the line connecting the two second mounting holes 2-1 is 30-90 degrees, which facilitates the connection of the first metal member 1 to the vibrating wheel and the connection of the second metal member 2 to the roller frame via bolts. In this embodiment, the angle between the line connecting the two first mounting holes 1-1 and the line connecting the two second mounting holes 2-1 is 90 degrees (i.e., the two first mounting holes 1-1 and the two second mounting holes 2-1 are arranged in a cross shape).

[0027] In some embodiments, the diameter of the middle position of the rubber body 3 is 50 to 190 mm, and the diameters of the two ends where the rubber body 3 is connected to the metal part (i.e., the circular cross-section at the connection between the rubber body 3 and the metal part) are 1.1 to 1.3 times the diameter of the middle position, which is suitable for vibratory wheels of rollers of various tonnages.

[0028] The second aspect of the present invention further provides a vibratory roller, on which the vibratory wheel rubber damper is installed.

[0029] In the vibration wheel rubber shock absorber of the present invention, the rubber body 3 is in the shape of an inwardly concave spindle, and the generatrix is ​​an elliptical arc 3-1. The cross-section gradually increases from the middle to the two ends, thereby reducing stress and stress concentration and extending the service life of the shock absorber; the arc edge 3-2 on the rubber body 3 causes the cross-section of the rubber body from the center of the hole to the axis of rotation of the rubber body to gradually change, thereby reducing stress concentration and increasing the connection area between the rubber body 3 and the first metal part 1 and the second metal part 2, thereby reducing the stress at the connection and extending the service life of the shock absorber.

[0030] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
