[0021] like Figure 1 to Figure 2 As shown, a hanging bearing comprises a fixing plate 1 and a mounting ring 2, wherein the mounting ring 2 is fixedly mounted on the fixing plate 1, a spherical bearing is mounted inside the mounting ring 2, an oil hole 3 is provided on the mounting ring 2, an outer ring oil hole 5 communicating with the oil hole 3 is provided on the outer ring 4 of the spherical bearing, and lubricating oil enters between the inner ring 6 and the outer ring 4 of the spherical bearing from the oil hole 3 through the outer ring oil hole 5. The spherical bearing is adopted, which is convenient and time-saving to install and disassemble, and lubrication is performed through the oil hole, and the service life is extended. A connecting column 19 is fixedly mounted between the fixing plate 1 and the mounting ring 2.

[0022] like Figure 1 As shown, an oil pipe 7 extending up and down is fixedly mounted on the fixed plate 1, and the lower end of the oil pipe 7 is connected to the oil hole 3. The oil guide pipe is used to inject lubricating oil, and the lubricating oil enters the oil hole 3 along the oil guide pipe, thereby ensuring the lubrication effect. In this embodiment, the oil pipe 7 is inserted into the oil hole 3 and is connected to the outer ring oil hole 5.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, preferably, the inner surface of the outer ring 4 of the spherical bearing is provided with an oil groove connected to the outer ring oil through hole 5, and the oil groove includes a first section 8 and a fifth section 9 connected to the outer ring oil through hole 5, the first section 8 and the fifth section 9 extend along the circumferential direction of the inner ring 6, the first section 8 is located on the left side of the outer ring oil through hole 5, and the fifth section 9 is located on the right side of the outer ring oil through hole 5, the end of the first section 8 is connected to the second section 10 inclined to the first section 8, the end of the fifth section 9 is connected to the fourth section 11 inclined to the fifth section 9, the end of the second section 10 is connected to the third section 12, the third section 12 extends to the end of the fourth section 11, and the first section 8, the second section 10, the third section 12, the fourth section 11 and the fifth section 9 are all connected to each other. The end of the first section 8 is connected to the second section 10 inclined to the first section 8, and the end of the fifth section 9 is connected to the fourth section 11 inclined to the fifth section 9, so that the lubricating oil can lubricate a larger range in the axial direction of the spherical bearing, further ensuring the lubrication effect.

[0024] Preferably, Figure 4 As shown, the included angle between the second section and the first section is 120°, and the included angle between the fourth section 11 and the fifth section 9 is 120°.

[0025] like Figure 4As shown, the width of the first section 8 is greater than that of the second section 10, and the width of the fifth section 9 is greater than that of the fourth section 11. This allows lubricating oil to more easily enter the first section and the fifth section.

[0026] like Figure 5 As shown, in order to further expand the lubrication range of the lubricating oil, the third section 12 is provided with a plurality of side lubrication sections 13 extending along the axial direction of the inner ring.

[0027] like Figure 1 As shown, a U-shaped fixing bolt 14 is detachably fixedly mounted on the fixing plate 1, and the U-shaped fixing bolt 14 is supported on the lower part of the mounting ring 2, thereby ensuring that the mounting ring is firmly fixed.

[0028] like Figure 1 and Figure 2 As shown, end covers 15 are detachably fixedly mounted at both ends of the mounting ring 2, and a through hole is provided on the end cover 15 for the suspension shaft 17 to pass through. A sealing ring 16 is provided between the end cover 15 and the spherical bearing, and an end cover fixing bolt 18 is provided between the end cover 15 and the mounting ring.

[0029] There is a transition fit between the inner ring 6 of the spherical bearing and the suspension shaft 17. The suspension shaft is inserted into the inner ring and transitionally fits with the inner ring 6.

[0030] like Figure 4 As shown, the first section 8 and the fifth section 9 are staggered with each other in the circumferential direction of the inner ring of the spherical bearing, and the second section 10 is inclined forward in the axial direction of the mounting ring 2 relative to the first section 8. Figure 4 The direction of the middle arrow is the front of the axis direction of the mounting ring 2, and the fourth section 11 is inclined relative to the fifth section 9 toward the rear of the axis direction of the mounting ring 2. In this way, when the inner ring rotates toward the opening of the first section, the inner ring drives the lubricating oil to enter the opening of the first section, and is blocked by the outer ring oil-passing hole walls on both sides of the opening of the first section. Since the first section 8 and the fifth section 9 are staggered with each other in the circumferential direction of the inner ring of the spherical bearing, a part of the lubricating oil blocked by the outer ring oil-passing hole walls on both sides of the opening of the first section moves toward the opening direction of the fifth section, thereby prompting this part of the lubricating oil to enter the fifth section. Correspondingly, when the inner ring rotates toward the opening of the fifth section, the inner ring drives the lubricating oil to enter the opening of the fifth section, and the lubricating oil blocked by the outer ring oil-passing hole walls on both sides of the opening of the fifth section is easier to enter the opening of the first section, thereby effectively improving the lubrication efficiency, ensuring effective lubrication between the inner ring and the outer ring, and extending the service life of the equipment.
