Description

Technical Field

[0001] The utility model relates to the technical field of bearing lubrication, in particular to an immersion lubrication device for a bearing. Background Art

[0002] Immersion lubrication of bearings is a lubrication method in which the bearings are immersed in lubricating oil, allowing the bearings to fully absorb the lubricating oil, thereby alleviating the friction between the bearings and the shaft. This method is also one of the most commonly used and simple lubrication methods. It has the advantages of long-lasting lubrication, reduced friction and wear, and lower operating temperature.

[0003] However, the existing immersion lubrication device for bearings generally places the bearings directly into the lubricating liquid, which is not only inconvenient for the installation of the bearings, but also has a poor sealing effect, which easily causes the lubricating liquid to overflow from the bearing connection, resulting in serious loss of the lubricating liquid.

[0004] To this end, we provide a bearing immersion lubrication device to solve the above problems. Utility Model Content

The No. 1 dynamic ring 9 is slidably connected with the No. 1 static ring 6, and the No. 2 dynamic ring 10 is slidably connected with the No. 2 static ring 7. Therefore, the No. 1 static ring 6 fits with the No. 1 dynamic ring 9 under the action of the No. 1 spring 4 to achieve the mechanical seal of the outer wheel of the bearing 8. The No. 2 static ring 7 fits with the No. 2 dynamic ring 10 under the action of the No. 2 spring 5 to achieve the mechanical seal of the inner wheel of the bearing 8, thereby preventing the lubricating fluid from overflowing from the bearing 8. Moreover, since both are mechanical seals, the friction force and resistance generated are very small, and therefore will not interfere with the rotation of the bearing 8.

[0025] A liquid injection pipe 11 is provided at the side end of the plate shell 1, and the liquid injection pipe 11 is connected to the ball ring of the bearing 8. Lubricating liquid can be injected into the space between the bearing 8 and the two plate shells 1 through the liquid injection pipe 11. An observation window 13 is provided in the plate shell 1. The height of the observation window 13 is consistent with the height of the lowest end ball of the bearing 8. The amount of lubricating liquid added can be conveniently checked through the observation window 13. According to scientific experiments, it is most appropriate when the liquid level of the lubricating liquid is located near the center of the lowest ball of the bearing 8. Therefore, when the liquid level of the lubricating liquid is observed from the observation window 13 to reach a suitable position, the addition can be stopped. A plug 12 is provided at the upper end of the liquid injection pipe 11. After the lubricating liquid is added, the plug 12 is used to close the liquid injection pipe 11 to prevent dust from entering the bearing 8 and causing wear thereon.

[0027] Working principle: first fix one plate shell 1 through the fixing hole 18, then place the bearing 8 into the fixing ring groove 16 of the plate shell 1, then place the other plate shell 1 on the side end of the bearing 8, and insert the track rod 19 of the plate shell 1 placed at the rear into the track hole 20 of the plate shell 1 fixed in front, and at the same time, the track rod 19 of the plate shell 1 fixed in front will also be inserted into the track hole 20 of the plate shell 1 placed at the rear, so that the threaded tubes 15 at the side ends of the two plate shells 1 will be aligned, and the bolts are passed through the two corresponding threaded tubes 15, and then the bolts are rotated to drive the plate shell 1 placed at the rear to move in the direction of the plate shell 1 fixed in front until the fixing ring grooves 16 of the two plate shells 1 are aligned.
