Description

Technical Field

[0001] This utility model relates to the field of needle roller bearing testing technology, and in particular to a needle roller bearing post-assembly testing oil leveling device. Background Technology

[0002] Needle roller bearings are a type of rolling bearing that uses cylindrical rollers to maintain the spacing between the inner and outer rings. Compared to other types of rolling bearings, needle roller bearings use rollers (needles) with small diameters but long lengths. Therefore, needle roller bearings have a higher radial load capacity and are suitable for applications that bear heavy loads and impact loads. Needle roller bearings replace sliding friction with rolling friction, which significantly reduces the friction between rotating parts, thereby reducing energy loss and improving mechanical efficiency. Needle roller bearings can support rotating parts (such as shafts, hubs, etc.), bear radial loads, and maintain the stability and accuracy of rotating parts.

[0003] In existing technology, lubricating oil plays a lubricating role in needle roller bearings, reducing friction and wear between the needle rollers and the inner and outer rings. If the lubricating oil is not distributed evenly, it will lead to insufficient lubrication in some areas, increasing friction and wear, and shortening the service life of the bearing. After the needle roller bearing is assembled, it is necessary to check whether the oil coating inside the needle roller bearing is uniform. However, existing testing devices cannot simultaneously test multiple surfaces of the inner wall of the needle roller bearing, thus reducing the accuracy of testing whether the oil coating inside the needle roller bearing is uniform. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing testing devices cannot simultaneously test multiple surfaces of the inner wall of a needle roller bearing during use, and to propose a needle roller bearing assembly testing oil leveling device.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, after the needle roller bearing is limited to the corresponding position and the camera is positioned in the center of the needle roller bearing, the controller starts the drive motor, which drives the drive rod and the first gear to rotate. Then, under the action of the circular groove, three arc-shaped sliders and the connecting plate, it drives the second gear to rotate stably and uniformly, thereby driving the limited needle roller bearing to rotate and rotate around the camera at a uniform speed.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4 As shown, this utility model provides a device for testing and evenly distributing oil after assembly of needle roller bearings. It includes an operating table 1, a circular groove 2 on the top of the operating table 1, three arc-shaped sliders 3 movably embedded in the inner wall of the circular groove 2, a connecting plate 4 fixedly installed between the tops of the three arc-shaped sliders 3, an L-shaped plate 5 fixedly installed at the bottom of the operating table 1, a drive motor 6 fixedly installed at the top of the L-shaped plate 5, a drive rod 7 fixedly installed at the top of the drive motor 6, a first gear 8 fixedly installed at the top of the outer wall of the drive rod 7, a second gear 9 meshing with the outer wall of the first gear 8, and the bottom of the second gear 9 fixedly connected to the top of the connecting plate 4.

[0024] The overall effect of Embodiment 1 is that when the ball bearing is limited to a designated position, and the camera 20 is simultaneously positioned in the middle of the needle bearing, the camera 20, being a high-resolution camera, captures images of the inner side of the needle bearing. Then, the controller 21 activates the drive motor 6 mounted on the L-shaped plate 5, causing the drive rod 7 to rotate inside the operating table 1, simultaneously rotating the first gear 8. Because a circular groove 2 is opened at the top of the operating table 1, and three arc-shaped sliders 3 are movably embedded in the inner wall of the circular groove 2, and the connecting plate 4 mounted at the bottom of the second gear 9 is fixedly connected to the top of the three arc-shaped sliders 3, thereby... The rotation of the first gear 8 drives the second gear 9 to rotate stably and uniformly. Its rotation speed can be adjusted as needed, thereby driving the limited needle roller bearing to rotate and rotate uniformly around the camera 20. This allows each area inside the needle roller bearing to be captured and recorded, and the image information is transmitted to the corresponding image processing software. The uniformity of the oil coating is judged by the characteristics of the oil film, such as color and brightness. For example, a brightness threshold can be set. If the brightness of a certain area is lower than the threshold, it is considered that the oil coating on the inner area of ​​the needle roller bearing is uneven, thereby improving the accuracy of detecting whether the oil coating on the inner side of the needle roller bearing is uniform.

[0025] Example 2: Figures 2-4 As shown, a placement plate 10 is fixedly installed on the top of the second gear 9. Two lifting columns 11 are fixedly installed on the top of the placement plate 10. A servo motor 12 is fixedly installed on the top of each of the two lifting columns 11. A threaded rod 13 is fixedly installed on the bottom of each of the two servo motors 12. A moving block 14 is threadedly connected to the outer wall of each of the two threaded rods 13. The outer wall of each of the two moving blocks 14 is movably embedded inside the two lifting columns 11. An electric push rod 15 is fixedly installed on one side of the outer wall of each of the two moving blocks 14. A limit clamp 16 is fixedly installed at the output end of each of the two electric push rods 15. A fixed frame 17 is fixedly installed on the top of the operating table 1. A U-shaped frame 18 is fixedly installed on the top of the fixed frame 17. A cylinder 19 is fixedly installed on the top of the inner wall of the U-shaped frame 18. A camera 20 is installed at the output end of the cylinder 19. A controller 21 is fixedly installed on the top of the operating table 1. One side of the outer wall of the controller 21 is electrically connected to the outer wall of the drive motor 6, the two servo motors 12, and the two electric push rods 15.

[0026] The effect achieved by the entire embodiment 2 is as follows: the needle roller bearing to be tested is placed on the placement plate 10, and the electric push rod 15 installed on one side of the outer wall of the two moving blocks 14 is started by the controller 21 at the same time, so that the two limiting clamps 16 can move relative to each other, thus clamping the needle roller bearing. Then, the two servo motors 12 are started by the controller 21 at the same time, so that the two threaded rods 13 can rotate inside the two lifting columns 11. Since the two moving blocks 14 are movably embedded inside the two lifting columns 11 and are also threadedly connected to the two threaded rods 13, the two moving blocks 14 can be moved upward at the same time, and the limited needle roller bearing can be moved upward a suitable distance. Then, the cylinder 19 is started by the controller 21, so that the camera 20 can be moved downward a suitable distance, and the camera 20 is placed in the middle of the needle roller bearing, which helps to improve the accuracy of subsequent testing on whether the oil coating is uniform.

[0027] Working principle: First, the needle roller bearing whose oil coating needs to be tested is placed in the middle of the placement plate 10. Then, the controller 21 simultaneously starts two electric push rods 15, causing them to move the two limit clamps 16 relative to each other and limit them in place. Next, the controller 21 simultaneously starts two servo motors 12, causing them to move two moving blocks 14 on the two lifting columns 11 and two threaded rods 13, thereby moving the two electric push rods 15, the two limit clamps 16, and the needle roller bearing to a suitable height. Then, the controller 21 starts the cylinder 19, causing it to move the camera 20 downward a suitable distance and position it in the middle of the needle roller bearing. Immediately afterwards, the controller 21 starts the drive motor 6, causing it to drive the drive rod 7 and the... When gear 8 rotates, the connecting plate 4 is installed at the bottom of the second gear 9. The three arc-shaped sliders 3 installed at the bottom of the connecting plate 4 are movably embedded in the circular groove 2. The second gear 9 meshes with the first gear 8. Thus, the uniform rotation of the first gear 8 can drive the second gear 9 and the three arc-shaped sliders 3 to rotate stably and uniformly in the circular groove 2. This, in turn, drives the placement plate 10, the two lifting columns 11, and the limited needle roller bearing to rotate uniformly. This allows the camera 20 to capture multiple areas of the inner wall of the needle roller bearing and transmit the image information to the image analysis software. By analyzing the characteristics such as the color or brightness of the oil film, it can be determined whether the inner side of the needle roller bearing is evenly coated with oil, thereby improving the accuracy of detecting whether the inner side of the needle roller bearing is evenly coated with oil.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
