Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a bearing with a ceramic support. Background Technology

[0002] Bearings with ceramic cages are bearings in which the cage (also called the support) is made of ceramic material. Ceramic cages are lightweight, which can reduce centrifugal force when the bearing rotates at high speed, reduce energy loss, and increase the bearing's limiting speed. Therefore, they are particularly suitable for high-speed rotating mechanical parts. Their high hardness and low coefficient of thermal expansion can maintain good dimensional stability at different operating temperatures, which helps maintain the high precision of the bearing and ensure the stable operation of the equipment. Bearings with ceramic cages are widely used in aerospace, high-speed precision machine tools, electronic manufacturing equipment, medical devices, new energy vehicles and other fields with high requirements for bearing performance.

[0003] However, existing bearings with ceramic supports are not easy to align with other bearings. When bearings need to bear large axial loads or when rotational accuracy needs to be improved, they are often installed side by side. In this case, the bearings need to be aligned in advance to facilitate their accurate installation into the shaft or bearing housing. However, the traditional alignment method is manual, which is time-consuming and has low alignment accuracy, affecting subsequent side-by-side installation and use.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

[0005] The purpose of this invention is to provide a bearing with a ceramic support to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] An embodiment of this utility model provides a bearing with a ceramic support, including an outer ring, a protrusion fixedly connected to the outer surface of the outer ring near its edge, a groove formed near the protrusion of the outer ring, and an indicator fixedly connected to the outer surface of the outer ring near its center.

[0008] Furthermore, the inner wall of the outer ring abuts against a plurality of balls, the side of the balls away from the outer ring abuts against the inner ring, the outer surface of the balls is slidably connected to a support body, the inner wall of the outer ring is provided with a first groove, and the outer surface of the inner ring is provided with a second groove.

[0009] Furthermore, a heat dissipation groove is provided on the outer ring near the indicator, and a sealing gasket is fixedly connected to the inner wall of the outer ring near its center.

[0010] Furthermore, an injection hole is provided on the outer ring near the heat dissipation groove, and a dust cover is fixedly connected to the inner wall of the outer ring near the protrusion.

[0022] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0023] like Figures 1 to 4 As shown, a bearing with a ceramic support is characterized in that: it includes an outer ring 1, a protrusion 31 is fixedly connected to the outer surface of the outer ring 1 near its edge, a groove 32 is provided on the outer ring 1 near the protrusion 31, and an indicator 33 is fixedly connected to the outer surface of the outer ring 1 near its center.

[0024] In this embodiment of the utility model, when in use, the two bearings are arranged in a "back-to-back", "face-to-face", or "tandem" manner. One bearing is rotated 90 degrees and brought closer to the other bearing. The groove 32 of one bearing is aligned with the protrusion 31 of the other bearing. The two bearings fit together and are aligned, which facilitates subsequent side-by-side installation. The auxiliary alignment structure on the outer ring 1 of the bearing facilitates the guidance of the three connection processes of the bearing, thereby making it convenient for workers to install the bearings side by side.

[0025] Each bearing has two protrusions 31 fixedly connected to both sides of the outer ring 1, and two grooves 32 are opened on each side. Since the protrusion distance of the protrusions 31 is very small, when the bearing is used alone, the protrusions 31 and grooves 32 will not affect the normal operation of the bearing. When two bearings need to be installed side by side, only one bearing needs to be rotated to snap all the protrusions 31 into the grooves 32 to align the bearings, which solves the problem of the troublesome and time-consuming traditional manual alignment.

[0026] In addition, the indicator 33 on the outer ring 1 makes it easier for workers to distinguish the front and back of the bearing and select the appropriate alignment method for side-by-side installation, such as "face-to-face", "back-to-back" and "tandem". This is existing technology and will not be explained in detail.

[0027] like Figures 1 to 4 As shown, a number of balls 21 abut against the inner wall of the outer ring 1, and the inner ring 22 abuts against the side of the balls 21 away from the outer ring 1. The outer surface of the balls 21 is slidably connected to the support body 23. A first groove 24 is opened on the inner wall of the outer ring 1, and a second groove 25 is opened on the outer surface of the inner ring 22.

[0028] In this embodiment of the invention, during use, the ball 21 rolls in the second groove 25 of the inner ring 22 and simultaneously rolls in the first groove 24 of the outer ring 1. The bearing bracket rotates as the ball 21 rolls, and the bearing begins to work.

[0029] When two bearings need to be installed side by side, they must first be aligned. There are alignment methods such as "face to face", "back to back" and "tandem", which are existing technologies and will not be explained in detail.

[0030] like Figures 1 to 4 As shown, a heat dissipation groove 41 is provided on the outer ring 1 near the indicator 33, and a sealing gasket 42 is fixedly connected to the inner wall of the outer ring 1 near its center.

[0031] In this embodiment of the utility model, during use, the ball 21 rolls in the groove between the inner ring 22 and the outer ring 1, and rolls inside the bearing. The heat generated during the process is dissipated through the sealing gasket 42 and then through the heat dissipation groove 41, ensuring the internal temperature of the bearing is stable, thereby ensuring its performance is stable. Since the sealing gasket 42 blocks the heat dissipation groove 41, the lubricant will not leak out while dissipating heat.

[0032] Among them, the sealing gasket 42 has the function of fluorosilicone rubber, which can not only ensure the sealing between the heat dissipation groove 41 and the bearing, but also ensure heat dissipation. In addition, it can play a certain role in shock absorption and prevent the outer ring 1 from being deformed due to external pressure.

[0033] In addition, the heat dissipation groove 41 has a trapezoidal cross-section that is wider at the top and narrower at the bottom, which reduces the possibility of the lubricant inside the bearing flowing out of the heat dissipation groove 41 through the gap of the sealing gasket 42.

[0034] like Figures 1 to 4 As shown, an injection hole 51 is provided on the outer ring 1 near the heat sink 41, and a dust cover 52 is fixedly connected to the inner wall of the outer ring 1 near the protrusion 31.

[0035] In this embodiment of the utility model, lubricant can be added to the inside of the bearing through the injection hole 51 to ensure that the rolling balls 21 inside the bearing roll smoothly, thereby ensuring that the bearing rotates smoothly. The dust cover 52 blocks external dust and prevents external impurities from entering the bearing and affecting the operation of its internal precision components.

[0036] Dust covers 52 are installed on both sides of the outer ring 1 to ensure the stability of the bearing.

[0037] like Figures 1 to 4 As shown, the protrusions 31 and grooves 32 are evenly distributed on the outer surface of the outer ring 1.

[0038] In this embodiment of the utility model, when in use, two bearings are arranged in a "back-to-back", "face-to-face", or "tandem" manner. One bearing is rotated 90 degrees and brought closer to the other bearing. The groove 32 of one bearing is aligned with the protrusion 31 of the other bearing. The two bearings fit together and are aligned, which facilitates subsequent side-by-side installation. The auxiliary alignment structure on the outer ring 1 of the bearing facilitates the guidance of the three connection processes of the bearing, thereby making it convenient for workers to install the bearings side by side.

[0039] Two protrusions 31 and two grooves 32 are evenly distributed on the outer ring 1 to ensure uniform force distribution.

[0040] like Figures 1 to 4 As shown, ball 21 is located between groove 1 24 and groove 2 25.

[0041] In this embodiment of the invention, during use, the ball bearing 21 rolls simultaneously within the first groove 24 and the second groove 25.

[0042] Among them, the ball bearing 21, the first groove 24 and the second groove 25 are all provided in two sets, so that even if a single component of one set is damaged, the other set can still enable the bearing to continue to work.

[0043] like Figures 1 to 4 As shown, two dust covers 52 are evenly distributed on both sides of the outer ring 1.

[0044] In this embodiment of the invention, when in use, the dust cover 52 effectively prevents solid particles such as dust, sand, metal shavings, and fibers from entering the bearing.

[0045] Dust covers 52 are provided on both sides of the outer ring 1, providing more comprehensive protection and extending the service life of the bearing.

[0046] Working principle: In use, two bearings are placed in a "back-to-back", "face-to-face", or "tandem" configuration. One bearing is rotated 90 degrees and brought close to the other bearing. The groove 32 of one bearing aligns with the protrusion 31 of the other bearing, and the two bearings fit and align, facilitating subsequent side-by-side installation. The auxiliary alignment structure on the outer ring 1 of the bearing facilitates the three connection processes of the bearing, making it easier for workers to install the bearings side-by-side. The balls 21 roll in the groove between the inner ring 22 and the outer ring 1, and roll inside the bearing frame. The heat generated during the process is dissipated through the sealing gasket 42 and then through the heat dissipation groove 41, ensuring stable internal temperature of the bearing and thus ensuring stable performance. Since the sealing gasket 42 blocks the heat dissipation groove 41, lubricant will not leak out while dissipating heat.

[0047] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
