Description

Technical Field

[0001] The utility model relates to a low-noise bearing. Background Art

[0002] With the continuous development of modern industrial technology, the application of mechanical equipment in various fields is becoming more and more extensive, and the requirements for its performance and reliability are also increasing. Among them, bearings are key components in mechanical equipment, and their operating status directly affects the overall performance of the equipment. During operation, traditional bearings often generate loud noise due to factors such as friction, vibration, and material properties. This not only affects the operating environment of the equipment, but can also cause equipment failure and shorten its service life. Therefore, the market demand for low-noise bearings is increasing.

[0003] Existing ball bearings are mainly used to bear radial loads when in use, and have poor bearing capacity for axial loads. When used in an environment with a large axial load, the friction between the balls and the bearings is large, which easily generates large noise. Utility Model Content

[0004] The purpose of the utility model is to provide a low-noise bearing that can reduce noise and improve axial load bearing capacity.

[0011] The utility model is further configured such that the oblique arrangement of the rolling elements can decompose the axial load accordingly, thereby enhancing the bearing capacity of the axial load.

[0012] The utility model is further configured such that two groups of axially symmetrically arranged rolling elements can balance radial and axial loads, thereby reducing stress concentration and instability problems caused by excessive load in one direction.

[0013] The utility model is further configured such that two groups of axially symmetrically arranged rolling elements can provide additional support and stability, reduce the deflection and deformation problems of a single group of rolling elements, and offset unbalanced torque, thereby reducing vibration and noise.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0022] In the description of this utility model, "plurality" means two or more, unless otherwise clearly defined. In this utility model, unless otherwise clearly defined and defined, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, an indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a low-noise bearing comprises an inner ring 1 and an outer ring 2. A cage 3 is disposed between the inner ring 1 and the outer ring 2. Multiple rolling elements 4 surround the cage 3, with both sides of the rolling elements 4 contacting the inner ring 1 and the outer ring 2, respectively. This allows the bearing to support the rotating shaft connected to the bearing. This is prior art and will not be described in detail.

[0025] The core technical solutions of this application are as follows:

[0026] like Figure 2 、 Figure 3 As shown, to improve the ability to withstand axial loads, the inner ring 1 described in this application is provided with an oblique groove 5. The retaining frame 3 is truncated cone-shaped, compatible with the oblique groove 5. The rolling elements 4 disposed within the retaining frame 3 are flush with the retaining frame 3, meaning that the radial cross-section of the rolling elements 4 is an inclined surface. This arrangement allows the rolling elements 4 to rotate around the center of the inner ring 1 when the rotating shaft is connected to the inner ring 1 and rotates. When the rotating shaft is subjected to an axial load along the axis of the inner ring 1, the oblique arrangement of the rolling elements 4 can effectively break down the axial load, thereby enhancing the ability to withstand axial loads.

[0027] Since the rolling element 4 is arranged obliquely during use, the load it bears is unevenly distributed. Therefore, when bearing the load, the friction between the rolling element 4 and the inner ring 1 is enhanced, resulting in a large noise.

[0028] like Figure 3 、 Figure 4 To address the aforementioned high noise issue, the low-noise bearing described herein comprises two sets of inner ring 1, retainer 3, and rolling elements 4, arranged symmetrically about the bearing center. This arrangement balances the load within the bearing. Specifically, the two sets of axisymmetric rolling elements 4 balance radial and axial loads, reducing stress concentration and instability caused by excessive unidirectional loads.

[0029] In addition, the axisymmetric double set of rolling elements 4 provides additional support and stability, reduces the deflection and deformation problems of a single set of rolling elements 4, and can offset unbalanced torque, thereby reducing vibration and noise.

[0030] Optimally, the rolling element 4 described in the present application is set at an angle of 30-60 degrees, preferably 45 degrees. The angle of the rolling element 4 is adjusted according to the different radial and axial load bearing capacities required by the bearing to adapt to different application scenarios.

[0031] Optimally, two adjacent rolling elements 4 are staggered. By staggering the rolling elements 4, when a load in any direction is borne, it can be borne by at least one rolling element 4, thereby reducing the load in one direction and improving the load bearing capacity.

[0032] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
