Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. According to the different friction properties of the moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, their radial dimensions, vibrations and noise are larger, and their prices are also higher. Rolling bearings generally consist of four parts: an outer ring, an inner ring, rolling elements and a cage. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

The first sealing plate 5 is connected to one side of the upper bearing body 1 and the lower bearing body 13 through a second bolt 9, and a stop washer 18 is installed on the top of the first fixing plate 8, and the third bolt 16 is used in conjunction with the stop washer 18. A movable shaft 6 is movably installed between the upper bearing body 1 and the lower bearing body 13, and a connecting plate 15 is installed at one end of the movable shaft 6. The connecting plate 15 extends out of the interior of the upper bearing body 1 and the lower bearing body 13, and multiple sealing rings 7 are installed at equal distances inside one end of the movable shaft 6.

[0022] Specifically, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, since the first connecting seat 3 and the second connecting seat 10 are respectively installed on one side of the upper bearing body 1 and the lower bearing body 13, and multiple first bolts 4 are respectively installed on one side of the first connecting seat 3 and the second connecting seat 10 at equal distances, the upper bearing body 1 and the lower bearing body 13 can be fixed by the first connecting seat 3 and the second connecting seat 10. Since the first sealing sheet 5 and the second sealing sheet 14 are respectively installed on both sides of the upper bearing body 1 and the lower bearing body 13, the first sealing sheet 5 and the second sealing sheet 14 can be used to seal both sides of the upper bearing body 1 and the lower bearing body 13 to avoid leakage of lubricant inside the upper bearing body 1 and the lower bearing body 13, thereby improving the sealing of the bearing. Since the upper bearing body 1 and the lower bearing body 13 are movably installed with a movable shaft 6, and one end of the movable shaft 6 is installed with a connecting plate 15, it can be connected to the output end of the pump body through the connecting plate 15 to ensure the normal use of the pump body.

[0023] Working principle: When in use, after stacking the first fixing plates 8 installed on both sides of the upper bearing body 1 and the second fixing plates 11 installed on both sides of the lower bearing body 13, the upper bearing body 1 and the lower bearing body 13 can be installed by fixing the first fixing plates 8 and the second fixing plates 11 through the third bolts 16. Since the first connecting seat 3 and the second connecting seat 10 are respectively installed on one side of the upper bearing body 1 and the lower bearing body 13, and a plurality of first bolts 4 are respectively installed on one side of the first connecting seat 3 and the second connecting seat 10 at equal distances, The second connecting seat 10 can fix the upper bearing body 1 and the lower bearing body 13. Since the first sealing sheet 5 and the second sealing sheet 14 are respectively installed on both sides of the upper bearing body 1 and the lower bearing body 13, the first sealing sheet 5 and the second sealing sheet 14 can be used to seal the upper bearing body 1 and the lower bearing body 13 to avoid leakage of the lubricant inside the upper bearing body 1 and the lower bearing body 13. Since the upper bearing body 1 and the lower bearing body 13 are movably installed with a movable shaft 6 inside, and one end of the movable shaft 6 is installed with a connecting plate 15, through The connecting plate 15 can be connected to the output end of the pump body to ensure the normal use of the pump body. When the bearing is maintained, since the bottom of the lower bearing body 13 is equipped with a plug 12, the lubricant inside the upper bearing body 1 and the lower bearing body 13 can be removed by rotating the plug 12 from the bottom of the lower bearing body 13, so that the lubricant inside the upper bearing body 1 and the lower bearing body 13 can be quickly discharged and replaced. Since the top of the upper bearing body 1 is equipped with a straight-through pressure injection oil cup 2, and the straight-through pressure injection oil cup 2 is installed, the lubricant inside the upper bearing body 1 and the lower bearing body 13 can be quickly discharged and replaced. The oil cup 2 is connected to the interior of the upper bearing body 1. Therefore, the lubricant required for the interior of the upper bearing body 1 and the lower bearing body 13 can be injected into the interior of the upper bearing body 1 and the lower bearing body 13 through the straight-through pressure injection oil cup 2, thereby realizing the rapid addition of lubricant to the interior of the upper bearing body 1 and the lower bearing body 13. The bearing can be quickly inspected and maintained, avoiding the tedious operation of dismantling the entire structure when repairing the bearing, facilitating the operation of maintenance personnel, avoiding damage to the pump body and the bearing body, and increasing the service life of the bearing.
