As shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, fig. 8, fig. 9, fig. 10, a bearing housing with lubricating oil cooling and oil leakage prevention comprises a bearing housing bottom 1, a bearing housing cover 2, an oil-repellent collar cover 3 and a bearing 5. The bearing box bottom 1 and the bearing box cover 2 form a bearing box after being fastened through screws. Two ends of the bearing box are respectively provided with a shaft hole 4. The oleophobic shaft sleeve 3 is arranged in the shaft hole 4. The two shaft holes 4 correspond to the two oleophobic shaft sleeve sleeves 3. The axes of the two shaft holes 4 are coincident. A bearing frame ring is arranged in the bearing box. The bearing frame ring is circular, is used for installing and fixing the bearing 5, and the axis of the bearing frame ring coincides with the axes of the two shaft holes 4. The bearing 5 is mounted on a bearing frame ring.
The axis of the shaft hole 4 is horizontal. The bearing box bottom 1 and the bearing box cover 2 are horizontally divided into an upper part and a lower part by the bearing box along the axle center of the axle hole 4. The lower part is a bearing box bottom 1, and the upper part is a bearing box cover 2. The bearing box bottom 1, as shown in fig. 7 and 8, includes a semicircular bearing frame ring bottom 13 and two semicircular shaft holes. The bearing housing cover 2, as shown in fig. 9, includes a semicircular bearing housing ring cover 23 and two semicircular shaft holes. After the bearing box bottom 1 and the bearing box cover 2 are fastened, the semicircular bearing frame ring bottom 13 and the semicircular bearing frame ring cover 23 jointly form a circular bearing frame ring. Two semicircular shaft holes on the bearing box bottom 1 and two semicircular shaft holes on the bearing box cover 2 jointly form two circular shaft holes 4. An oil overflow cavity 12 is arranged between the box wall of the semicircular shaft hole arranged on the bearing box bottom 1 and the semicircular bearing bracket ring bottom 13. Two oil overflow cavities 12 are respectively arranged at two ends of the ring bottom 13 of the semicircular bearing frame. The bottoms of the two oil spill cavities 12 are communicated with each other. A cavity 22 is arranged between the box wall of the bearing box cover 2 provided with the semicircular shaft hole and the semicircular bearing bracket ring cover 23. Two cavities 22 are respectively arranged at two ends of the semicircular bearing frame ring cover 23. The two oil overflow chambers 12 and the two cavities 22 correspond to each other to form two oil overflow chambers. That is, an oil overflow chamber is arranged between the wall of the bearing box provided with the shaft hole and the bearing frame ring. Two oil overflow chambers are respectively arranged at two ends of the bearing frame ring. The bottoms of the two oil spill cavities 12 communicate with each other, which also means that the bottoms of the two oil spill cavities communicate with each other. One of the two oil spill cavities 12 is provided with an oil outlet hole 11, which also means that the bottom of the oil spill cavity is provided with an oil outlet hole 11. The bearing box cover 2 is provided with an oil inlet 21. The oil inlet hole 21 is located above the semicircular bearing housing ring cover 23, which also means that the oil inlet hole 21 is located above the bearing housing ring. More specifically, as shown in fig. 10, an annular oil-wetting groove 51 is provided in the outer circumferential wall of the bearing 5 mounted on the pedestal ring. The oil lubrication groove 51 communicates with the inside of the bearing. The oil inlet hole 21 communicates with the oil lubrication groove 51 on the inner side. Furthermore, the bearing housing cover 2 is provided with hanging holes 29 for easy mounting. The bearing box bottom 1 is provided with a screw hole for fixing.
A semicircular annular first oil guide groove bottom 14 with an opening facing to the axis is arranged on the semicircular shaft hole of the bearing box bottom 1. The bottom of the first oil guide groove bottom 14 is provided with an oil guide channel 15 communicated with the oil overflow cavity 12. A semicircular annular first oil guide groove cover 24 with an opening facing to the axis is arranged on the semicircular shaft hole of the bearing box cover 2. The first oil guide groove bottom 14 and the first oil guide groove cover 24 are matched to form a first oil guide groove together. That is, the shaft hole is provided with a first oil guiding groove with an opening facing the shaft center. The first oil guide groove is annular. An oil guide channel 15 communicated with the oil spilling chamber is arranged between the bottom of the first oil guide groove and the oil spilling chamber. The oil guide passage 15 is arranged on the inner wall of the bearing box bottom 1.
And a semicircular second oil guide groove bottom 131 is arranged at two ends of the semicircular bearing frame annular bottom 13 along the circumferential direction. And a second oil guide groove cover 231 in a semicircular shape is arranged at two ends of the semicircular bearing frame ring cover 23 along the circumferential direction. The second oil guide groove bottom 131 and the second oil guide groove cover 231 are matched to form a ring-shaped second oil guide groove together. That is, two ends of the bearing frame ring are provided with annular second oil guide grooves. The second oil guide groove is an annular 45-degree edge cut at two ends of the bearing frame ring, and therefore the second oil guide groove is naturally communicated with oil overflow chambers at two ends of the bearing frame ring.
The oleophobic collar 3, as shown in fig. 5 and 6, includes a collar body and an oil baffle ring 32. The ring sleeve body of the oleophobic shaft ring sleeve 3 is of a circular ring cylinder structure, the axis of the oleophobic shaft ring sleeve is coincident with the axis of the bearing frame ring, the outer diameter of the oleophobic shaft ring sleeve is matched with the diameter of the shaft hole 4, and the inner diameter of the oleophobic shaft ring sleeve is matched with the diameter of the power shaft. Because the axle center of the bearing frame ring coincides with the axle center of the axle hole 4, the axle center of the ring sleeve body of the oleophobic axle ring sleeve 3 coincides with the axle center of the axle hole 4. An annular W-shaped oleophobic groove 34 is formed in the outer wall of the ring sleeve body. The W-shaped oil repellent groove 34 is a groove body having a "W" shaped cross section. The oil baffle ring 32 is located at one end of the ring sleeve body, is an annular body, has the same inner diameter as the ring sleeve body, and has an outer diameter larger than the diameter of the shaft hole 4. The inner side of a ring at one end of the ring sleeve body, which is provided with an oil baffle ring 32, is provided with a stepped annular first oil dredging groove 31. The oil baffle ring 32 has a certain thickness, and the other end of the oil baffle ring 32 facing the oil baffle ring 32 is provided with an annular second oil drain groove 33. The inner diameter of the second oil drainage groove 33 is matched with the diameter of the shaft hole 4, or the inner diameter of the second oil drainage groove 33 is the same as the outer diameter of the ring sleeve body.
The oil-repellent collar 3 is attached to the shaft hole 4 of the bearing housing, as shown in fig. 2, 3, and 4. The oleophobic shaft sleeve 3 is sleeved in the shaft hole 4. The oil baffle ring 32 on the oleophobic shaft sleeve 3 is positioned in the box body of the bearing box and clamped on the inner wall of the bearing box. The oil deflector ring 32 is not sealed against the inner wall of the bearing housing. The W-shaped oleophobic channel 34 on the oleophobic collar sleeve 3 faces the first oil guide channel, that is, the W-shaped oleophobic channel 34 faces the first oil guide channel cover 24 and the first oil guide channel bottom 14 up and down respectively. The width of the W-shaped oleophobic groove 34 is smaller than that of the first oil guide groove, so that the W-shaped oleophobic groove 34 is sealed in the range of the opening of the first oil guide groove by the groove walls on two sides of the first oil guide groove. The second oil drainage groove 33 faces outward. Because the oil guide passage 15 is a passage which is formed on the inner wall of the bearing box bottom 1 and is communicated with the first oil guide groove and the oil overflow chamber, the bottom of the second oil drain groove 33 faces the oil guide passage 15. Therefore, the oil guide passage 15 is communicated with not only the first oil guide groove but also the second oil drain groove 33.
The working principle of the embodiment is as follows: when the bearing seat is installed, the power shaft penetrates through the circular channel in the oleophobic shaft sleeve 3 to enter the box body of the bearing box and be connected with the bearing 5. That is, the oleophobic collar 3 is sleeved outside the power shaft. When the bearing seat works, cooled lubricating oil enters the box body of the bearing box from the oil inlet hole 21 and enters the bearing 5 through the oil wetting groove 51 on the bearing 5 to lubricate and cool the bearing 5. The lubricating oil overflowed from the lubricating oil groove 51 naturally flows into the oil overflow chamber through the second oil guide groove. The lubricating oil in the bearing 5 naturally flows into the oil overflow chamber after overflowing. The lubricating oil thrown or splashed out by the high-speed rotating bearing 5 is blocked by the inner wall of the bearing housing on the oleophobic collar 3 and the oil baffle ring 32. A large amount of lubricating oil on the inner wall of the bearing housing flows out of the bearing housing through a gap between the oil baffle ring 32 of the oil-repellent collar 3 and the inner wall of the bearing housing. Lubricating oil flowing to the outside of the bearing box through a gap between the oil baffle ring 32 and the inner wall of the bearing box is firstly dredged to the second oil dredging groove 33 under the dredging effect of the second oil dredging groove 33, and then flows into the oil overflowing chamber through the oil guiding channel 15 between the oil baffle ring 32 and the inner wall of the bearing box. A small amount of the lubricating oil in the second oil drain groove 33 flows out of the bearing housing through the gap between the oil drain collar 3 and the shaft hole 4. Lubricating oil flowing out of the bearing housing through the gap between the oil-repellent collar sleeve 3 and the shaft hole 4 is guided into the first oil guide groove by the action of the W-shaped oil-repellent groove 34 and the lubricating oil in the W-shaped oil-repellent groove 34 through the action of the W-shaped middle pointed top. The lubricating oil in the first oil guide groove flows into the oil overflow chamber through the oil guide passage 15. The lubricating oil blocked by the oil baffle ring 32 flows downwards along the plate surface of the oil baffle ring 32 and finally flows into the oil overflow chamber, but a small amount of lubricating oil flows out of the bearing box through a gap between the oil-repellent collar sleeve 3 and the power shaft. However, due to the dredging function of the first oil dredging groove 31, the lubricating oil flowing out of the bearing housing through the gap between the oil dredging collar 3 and the power shaft is dredged into the first oil dredging groove 31 and cannot flow out of the bearing housing. The first oil drain groove 31 naturally flows into the oil overflow chamber through the surface of the oil baffle ring 32. The lubricating oil in the oil spilling chamber is in a high-temperature state at this time, the high-temperature lubricating oil in the oil spilling chamber flows out of the bearing box through the oil outlet hole 11 by the oil pump for cooling, and the cooled lubricating oil is pumped into the bearing box by the oil pump through the oil inlet hole 21.
According to the working principle, the oil leakage prevention design based on the dredging mode is not the traditional oil leakage prevention design realized in a sealing mode. According to the working principle, the bearing box is not sealed with the outside, and lubricating oil flowing out of the bearing box body through the gap is drained to an oil spilling chamber through various groove body designs by the aid of the draining design of the gap between the oleophobic shaft sleeve 3 and the bearing box body.
Furthermore, it should be noted that due to the high speed rotation of the bearing 5, the oil deflector ring 32 will block much less oil than the oil on the inner wall of the bearing housing. In addition, in the present embodiment, the oil pressure at the oil inlet hole 21 is in a high pressure state. However, the oil overflow chamber is communicated with the outside through a gap, so that the oil overflow chamber is in a normal pressure state. In fact, the bearing housing is also difficult to seal due to the addition of the oleophobic collar 3 between the power shaft and the shaft bore of the bearing housing. Therefore, the pressure difference is mainly exhibited between the oil inlet hole 21 and the spill chamber. The pressure difference between the oil overflow chamber and the outside is very small. Also, the first oil evacuation groove 31 on the oleophobic collar 3 is already sufficient to evacuate the lubricating oil flowing out of the bearing housing through the gap between the oleophobic collar 3 and the power shaft into the first oil evacuation groove 31, compared to the complex structure of the oleophobic collar 3 and the inner wall of the bearing housing. If the pressure in the oil spilling chamber is large, the first oil repelling groove 31 is not enough to flow to the lubricating oil outside the bearing housing through the gap between the oil repelling collar sleeve 3 and the power shaft.
In addition, the lubricating oil on the oil baffle ring 32 flows into the oil spilling chamber more quickly. The outer annular wall of the oil baffle ring 32 is provided with a sharp-angled ring body 321. The cross-section of pointed ring 321 is a pointed ring.
