Description

Technical Field

[0001] The utility model belongs to the technical field of roller bearings, in particular to an oil filling and oiling device for a roller bearing box. Background Art

[0002] Roller bearings are important components that support the rolls and maintain their correct position in the mill frame. The requirements for roll bearings are low friction coefficient, sufficient strength, small deformation, long life, and easy roll replacement. The working characteristic of roll bearings is that they can withstand very high unit loads because they have to withstand considerable rolling forces in the shorter roll neck.

[0003] The lubrication method of the roller bearing box is one of the key factors to ensure the normal operation of mechanical equipment and extend the service life of the bearings. The current lubrication method for the bearings in the roller bearing box is to immerse the bearing part in lubricating oil and use the stirring during the operation of the bearing to bring the oil to other parts of the bearing. However, the oil supply through this lubrication method is not stable enough. During the operation of the bearing, friction between the rolling elements and the lubricating oil in the oil tank generates heat. If the speed is too fast, the oil temperature will be too high, causing the bearing temperature to be too high and damaged.

[0004] In view of this, the present invention proposes a roller bearing box oiling and oiling device to solve the above problems. Utility Model Content

[0005] In order to solve the problem of unstable oil supply, during the operation of the bearing, friction between the rolling elements and the lubricating oil in the oil tank generates heat.

The basic concept of the technical solution adopted by this utility model is:

An oil baffle seat is slidably installed on the inner wall of the bottom of the oil storage tank, and the top of the oil baffle seat is slidably set on the outer wall of the bottom of the partition, and an oil guide port is provided on the oil baffle seat. A rotating shaft is rotatably installed on the inner wall of the bottom of the oil storage tank, and a cam seat is fixedly connected to the outer wall of the rotating shaft. The cam seat is located on one side of the oil baffle seat, and a drive motor is fixedly installed on the outer wall of the bottom of the partition, and the output shaft of the drive motor is connected to the top position of the rotating shaft through a coupling.

[0007] As a preferred embodiment of the present invention, a tank cover is installed on the top of the oil storage tank, and an oil storage area is formed between the tank cover and the partition.

[0008] As a preferred embodiment of the present invention, a mounting hole is provided on the box cover, and a feeding pipe is fixedly connected to the inner wall of the mounting hole, and the feeding pipe is communicated with the oil storage area.

[0009] As a preferred embodiment of the present invention, a symmetrically arranged guide rod is fixedly installed on the inner side of the oil storage tank, a symmetrically arranged sliding hole is opened on the oil baffle seat, and the guide rod is slidably connected to the inner wall of the sliding hole.

[0010] As a preferred embodiment of the present invention, a symmetrically arranged compression spring is fixedly connected to the inner wall of one side of the oil storage tank, one end of the two compression springs is fixedly connected to the outer wall of one side of the oil baffle seat, and the compression springs are sleeved on the guide rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model clamps two sponge blocks on both sides of the roller bearing so that an extrusion force is formed between the two sponge blocks and the roller bearing. When the roller bearing needs to be lubricated during operation, the driving motor is started to drive the rotating shaft to rotate, and the rotating shaft drives the cam seat to rotate. When the cam seat rotates to contact the oil baffle seat, it can push the oil baffle seat to move, so that the oil guide port provided on the oil baffle seat moves to just below the oil outlet. At this time, the lubricating oil in the oil storage area can flow into the oil guide port through the oil outlet, and flow into the oil filling pipe through the oil guide port, and flow to the oil filling pipe. The lubricating oil at the bottom position flows to the two sponge blocks through two oil guide pipes, so that the lubricating oil is filled in the two sponge blocks. When the roller bearing rotates, the lubricating oil can be applied to the roller bearing through the two sponge blocks, thereby achieving the lubrication effect on the roller bearing. When the cam seat is detached from the surface of the oil baffle seat, the oil baffle seat is reset to its initial state, so that the oil baffle seat can seal the oil outlet, achieving the effect of quantitative oil filling and stable oil supply. This lubrication method can not only reduce friction and wear, but also effectively discharge friction heat to prevent the bearing temperature from being too high.
