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] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Bearing maintenance during daily use is very important, and lubrication is a key step to ensure the normal use of bearings. Effective lubrication can greatly increase the service life of bearings.

[0003] Immersion lubrication is also called oil bath lubrication. It refers to a lubrication method in which the bearing is immersed in lubricating oil and the lubricating oil is brought to other parts of the bearing after the bearing is rotated. This method is also one of the most common and simple lubrication methods. In actual use, considering the stirring loss and temperature rise during oil bath lubrication, there should be a certain limit on the height of the bearing immersed in the lubricating oil. According to scientific experiments, it is most appropriate to control the oil level near the center of the lowest ball of the bearing.

[0004] However, when existing bearings use immersion lubrication, it is difficult to control the amount of lubricating oil supplied. When there is too much lubricating oil, it will increase the resistance to bearing rotation and increase the temperature. When there is too little lubricating oil, the bearing will be difficult to lubricate, making it difficult for the bearing to be in the optimal lubrication state and even interfering with the operation of the bearing.

[0005] To this end, we provide a bearing immersion lubrication device to solve the above problems. Utility Model Content

[0007] The utility model aims to make up for the deficiencies of the prior art and provides an immersion lubrication device for a bearing.

[0008] 2) Technical solution

[0010] Furthermore, the lower end of the storage box is configured to be conical, and the discharge port is located at the lowest point, and when the floating plate is attached to the lower end of the baffle, the plug will be detached from the discharge port.

[0011] Furthermore, the plug is slidably connected in the discharge port, the gripping rod is located at the lower end of the storage box and a handle is provided at the side end.

[0012] Furthermore, a front protective plate is fixedly connected to the side end of the storage box, a circular clamping plate is fixedly connected to the rear end of the front protective plate, the outer ring of the bearing is clamped in the circular clamping plate, and the inner ring of the bearing is slidably connected to the front protective plate.

[0013] Furthermore, a slot is provided at the rear end of the circular card plate, and a rear protective plate is provided at the rear end of the circular card plate. The rear protective plate is connected to the circular card plate through the slot.

[0015] III) Beneficial effects

[0016] Compared with the prior art, the bearing immersion lubrication device has the following beneficial effects:

[0017] 1. The utility model provides a floating plate in the storage box. The sealing density of the floating plate is smaller than that of the lubricating oil, so that the floating plate can float on the surface of the lubricating oil. When the floating plate is located at the center of the ball at the lower end of the bearing, the lubricating oil has the best effect. If the lubricating oil continues to be added to the storage box, the plug will form a gap between the plug and the discharge port under the pull of the floating plate, so that excess lubricating oil leaks out of the discharge port. After the excess lubricating oil is discharged, the liquid level of the lubricating oil will drop, thereby causing the floating plate to drop, so that the plug blocks the discharge port again, so that the storage amount of the lubricating oil in the storage box can be maintained at the most appropriate position, solving the problem that it is difficult to control the oil supply of the existing bearing when using immersion lubrication, which makes it difficult for the bearing to be in the best lubrication state and even interferes with the operation of the bearing.

[0018] 2. The utility model provides a screen tube at the feeding port to filter the lubricating oil added to the storage box, thereby preventing lubricating oil solidification blocks and other impurities from entering the storage box, and protecting the operation of the bearing to prevent the impurities from causing wear to the bearing.

DETAILED DESCRIPTION

A discharge port 7 is opened at the lower end of the storage box 1, and the plug 5 is slidably connected in the discharge port 7. The lower end of the storage box 1 is set to a cone shape, and the discharge port 7 is located at the lowest point. When the lubricating oil needs to be discharged, it is only necessary to open the plug 5 to completely discharge the lubricating oil in the storage box 1. When the floating plate 4 is attached to the lower end of the baffle 3, a gap will be formed between the plug 5 and the discharge port 7, so that the lubricating oil can be discharged from the gap, wherein the baffle 3 is used to prevent the floating plate 4 from rising excessively, which causes the gap formed between the plug 5 and the discharge port 7 to be too large, thereby preventing the lubricating oil from flowing too fast and difficult to close in time.

[0027] The lower end of the plug 5 is fixedly connected to a grip rod 8, which is located at the lower end of the storage box 1 and has a handle on the side end. By lifting the grip rod 8 upward, the plug 5 can be lifted up, thereby disengaging it from the discharge port 7, so that the lubricating oil in the storage box 1 can be discharged. A feeding port 9 is provided at the upper end of the storage box 1, and the feeding port 9 is used to add lubricating oil to the storage box 1. A screen tube 10 is provided in the feeding port 9, and the screen tube 10 is used to filter out solidified blocks and other impurities in the lubricating oil. A plug 11 is provided in the feeding port 9, and the plug 11 is used to prevent dust in the air from falling into the storage box 1 during daily use.

[0028] The side end of the storage box 1 is fixedly connected with a front protective plate 12, and the rear end of the front protective plate 12 is fixedly connected with a circular clamping plate 13. The outer ring of the bearing is clamped in the circular clamping plate 13 to fix the bearing, and the inner ring of the bearing is slidably connected to the front protective plate 12.

[0029] A slot 14 is provided at the rear end of the circular card plate 13, and a rear guard plate 15 is provided at the rear end of the circular card plate 13. The rear guard plate 15 is connected to the circular card plate 13 through the slot 14, so that the rear guard plate 15 can be fixed. The rear guard plate 15 has the same structure as the front guard plate 12. A sealing ring 16 is provided in the rear guard plate 15, and the sealing ring 16 is slidably connected to the inner ring of the bearing. A spring 17 is fixedly connected to the rear guard plate 15, and the spring 17 is fixedly connected to the sealing ring 16. When the bearing is not running or running at a low speed, the sealing ring 16 is tightly attached to the inner ring of the bearing under the action of the spring 17 to achieve sealing. When the bearing runs at a high speed, a high-speed airflow will be generated between the sealing ring 16 and the inner ring of the bearing to achieve mechanical sealing, thereby preventing the lubricating oil from overflowing from the connection gap.

[0030] Working principle: The bearing is clamped in the circular clamping plate 13, and then fixed with the rear guard plate 15. The front guard plate 12 and the rear guard plate 15 can seal the inner ring of the bearing. The plug 11 in the feeding port 9 is opened, and lubricating oil is added to the storage box 1. During this period, the screen tube 10 filters the lubricating oil. As the lubricating oil is added, it will contact the floating plate 4. Since the density of the floating plate 4 is smaller than that of the lubricating oil, it can float on the liquid surface of the lubricating oil. The floating plate 4 rises and pulls the plug 5 upward through the connecting rod 6. When the floating plate 4 moves with the lubricating oil, the floating plate 4 will be When the oil level rises and hits the baffle 3, the plug 5 will just be separated from the discharge port 7, forming a gap between the two, so that the lubricating oil is discharged from the gap. When the lubricating oil is found to flow out of the discharge port 7, no more lubricating oil will be added to the storage box 1. As the lubricating oil is discharged, its liquid level will drop, and the floating plate 4 will drop with its liquid level, so that the plug 5 can be inserted into the discharge port 7 again to block the discharge of the lubricating oil. At this time, the liquid level of the lubricating oil will be just at the center of the ball at the lower end of the bearing, which can make the lubrication effect of the bearing in the best state.
