Description

Technical Field

[0001] The invention belongs to the field of bearing seats, in particular to a light bearing seat. Background Art

[0002] A high-pressure roller crusher is used to crush materials. Specifically, the main body of the high-pressure roller crusher is two rollers rotating in opposite directions. Brittle materials such as sand and gravel pass through the high-pressure roller crusher's feed mechanism and enter between two equal-sized, counter-rotating rollers. The top of the rollers pulls the material into the roller gap, where high pressure compresses the material into a dense cake. The material finally falls through the roller gap, passes through a discharge hopper, and is then transported to a conveyor.

[0003] Both rollers are mounted on bearing blocks at both ends via bearings. Some rollers use hydraulic cylinders to provide pressure. For example, according to utility model patent application number CN202321046516.0, a hydraulic ultra-fine crushing roller mill, each roller is mounted on a bearing block at both ends via bearings. The bearing block is fixed to a frame, the top of which is hinged to two hydraulic cylinders, and the bottom of which is hinged to the equipment base. The hydraulic cylinders can be extended or retracted to adjust the spacing between the two rollers and the pressure applied by the rollers to the material. The bearing blocks can be integrally formed with the frame, but this integral block is heavy and inconvenient to transport and install. Alternatively, the bearing blocks can be detachably connected to the frame. During assembly, the two bearing blocks are first mounted to the frame, followed by the ends of the rollers. This approach makes it difficult to ensure coaxiality between the two bearing blocks. In order to further reduce the difficulty of roller installation, there are currently many split bearing seats, that is, the bearing seats at both ends of the roller are divided into two parts, further reducing the weight of a single component, facilitating transportation and reducing the difficulty of installation and subsequent maintenance. However, when assembling the bearing seats, there are certain assembly errors, which in turn affect the assembly accuracy of the two bearing seats. Summary of the Invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below with reference to the accompanying drawings and examples.

[0031] The light bearing seat of the present invention is as follows Figures 1 to 9 As shown, it includes a first base body 1, a second base body 2, a third base body 3 and a fourth base body 4. The first base body 1 and the third base body 3 can form a bearing mounting seat at one end of the roller, and the second base body 2 and the fourth base body 4 can form a bearing mounting seat at the other end of the roller.

[0032] The first base 1 and the second base 2 are connected as a whole by a first connecting frame 5, and the third base 3 and the fourth base 4 are connected as a whole by a detachable second connecting frame 9. After assembly is completed, the second connecting frame 9 can be removed to avoid occupying space and affecting the installation of other components of the roller machine.

[0033] The first and third base bodies 1 and 3 are detachably connected, forming a first mounting hole. The second and fourth base bodies 2 and 4 are detachably connected, forming a second mounting hole. Bearings are installed in the first and second mounting holes. Both ends of the high-pressure roller machine are located within the bearings, which are self-aligning bearings.

[0034] The preparation method of the lightweight bearing seat of the present invention comprises:

[0035] The blanks of the first seat body 1, the second seat body 2, the third seat body 3 and the fourth seat body 4 are respectively cast using cast steel;

[0036] Rough machining of the blank;

[0037] Finishing of other structures other than the inner hole of the blank;

[0038] The first base body 1 and the second base body 2 are connected as a whole by a first connecting frame 5, and the third base body 3 and the fourth base body 4 are connected as a whole by a second connecting frame 9;

[0039] Connect the first base body 1 to the third base body 3, and the second base body 2 to the fourth base body 4, then clamp the whole body to the machining center, and fine-machine the first mounting hole and the second mounting hole;

[0040] After the precision turning is completed, the dimensional accuracy and positional accuracy of the first mounting hole and the second mounting hole are checked. When the accuracy meets the requirements, the connection between the first base body 1 and the third base body 3 is released, and the connection between the second base body 2 and the fourth base body 4 is released.

[0041] When the first mounting hole and the second mounting hole are finely machined, the entire bearing seat is clamped as a whole, which can ensure the position accuracy such as the coaxiality of the first mounting hole and the second mounting hole, thereby ensuring the installation accuracy of the roller.

[0042] The assembly method of the lightweight bearing seat of the present invention comprises:

[0043] Use auxiliary equipment such as tooling to fix the first base body 1, the second base body 2 and the first connecting frame 5;

[0044] Install the bearing sleeves at both ends of the roller, and then install the bearings at both ends of the roller into the inner holes of the first seat body 1 and the second seat body 2 respectively;

[0045] The first base body 1 is connected to the third base body 3, and the second base body 2 is connected to the fourth base body 4; the first base body 1 and the third base body 3 can be connected by bolts, and the second base body 2 and the fourth base body 4 can also be connected by bolts.

[0046] Remove the second connecting frame 9.

[0047] The present invention adopts the second connecting frame 9 as an auxiliary positioning part. During the finishing, transportation and assembly process, the third base body 3 and the fourth base body 4 are always connected as a whole through the second connecting frame 9. The relative positions of the third base body 3 and the fourth base body 4 are always kept fixed, which can reduce assembly errors.

[0048] A first connecting plate 11 is provided at the top of the first base body 1 and the second base body 2, and a first pin hole 6 is provided on the first connecting plate 11. A second connecting plate 7 is provided at the bottom of the first base body 1 and the second base body 2, and a second pin hole 8 is provided on the second connecting plate 7. The first pin hole 6 and the second pin hole 8 can be used to install pins, so that the first connecting plate 11 can be hinged to the hydraulic cylinder at the top, and the second connecting plate 7 can be hinged to the base at the bottom.

[0049] There are multiple second pin holes 8, for example, 2 or 3. By hingedly connecting different second pin holes 8 to the high-pressure roller machine base, the entire bearing seat and roller can be placed in different positions, thereby more flexibly adjusting the distance between the two rollers.

[0050] The first connecting frame 5 and the second connecting frame 9 can be various high-strength frames. As a preferred embodiment, the first connecting frame 5 is a hollow connecting column. The outer walls of the first base body 1 and the second base body 2 are provided with connecting sleeves 10, and the ends of the hollow connecting column are welded to the connecting sleeves 10. The second connecting frame 9 is a U-shaped frame, and the ends of the U-shaped frame can be respectively mounted to the third base body 3 and the fourth base body 4 by bolts.

[0051] When the high-pressure roller mill is working, it needs a large pressure to crush materials such as stones, and the load is large. Therefore, the load borne by the bearings and bearing seats is high, and they are prone to heat. In order to avoid overheating of the bearings and lubricating oil, the present invention is provided with cooling holes that penetrate the third body 3 and the fourth body 4 on the third body 3 and the fourth body 4. The inner port of the cooling hole is provided with a thermal expansion mechanism, which is a mechanism that expands after being heated. A heat pipe 13 is provided in the cooling hole, and an insulating sleeve 14 is fixedly provided on the outer wall of the heat pipe 13. The insulating sleeve 14 slides with the cooling hole, and one end of the heat pipe 13 is connected to the thermal expansion mechanism. The heat pipe 13 is a common heat dissipation element, and some bearing seats also use heat pipes 13 for heat dissipation. For example, the utility model patent with application number CN201620557374.8 discloses an excellent bearing seat with a heat dissipation effect. The existing heat pipe 13 is usually fixedly installed, and its condensation end is located outside the bearing seat. It is easily damaged by collision during transportation and assembly.

[0052] The heat pipe 13 mainly transfers heat through the phase change of the working fluid rather than heat conduction. In order to ensure the temperature difference between the two ends of the heat pipe 13 and improve the phase change efficiency, an insulating sleeve 14 is provided on the outer wall of the heat pipe to reduce the heat transferred to the heat pipe 13 by the third base body 3 and the fourth base body 4.

[0053] In the present invention, by providing a thermal expansion mechanism at the port of the cooling hole, when the high-pressure roller mill is operating, the temperature inside the bearing seat rises, the thermal expansion mechanism expands, and can push the heat pipe 13 outward, so that the condensation end of the heat pipe 13 extends out of the third seat body 3 or the fourth seat body 4. When the high-pressure roller mill is not operating, the temperature inside the bearing seat is at room temperature, the thermal expansion mechanism is in a contracted state, and the heat pipe 13 is entirely located in the cooling hole, which can protect the heat pipe 13 and prevent it from being damaged by collision.

[0054] In the present invention, the thermal expansion mechanism includes a heat-conducting tube 15, which is a circular tube fixed in the cooling hole. A first heat-conducting plate 16 is fixedly provided at the end of the heat-conducting tube 15 away from the heat pipe 13, and the first heat-conducting plate 16 seals the heat-conducting tube 15. A second heat-conducting plate 17 is provided at the end of the heat-conducting tube 15 facing the heat pipe 13, and the second heat-conducting plate 17 seals the heat-conducting tube 15. The second heat-conducting plate 17 slides with the heat-conducting tube 15, and a first working medium is provided in the heat-conducting tube 15. The heat pipe 13 is fixedly connected to the second heat-conducting plate 17, and a second working medium is provided in the heat pipe 13. The boiling point of the first working medium is lower than that of the second working medium. Specifically, the boiling point of the first working medium can be about 40 degrees Celsius, and the boiling point of the second working medium can be about 45 degrees Celsius. The second working medium can be water. By evacuating the heat pipe 13, the boiling point of the water is reduced to about 45 degrees Celsius. The heat conducting tube 15 , the first heat conducting plate 16 and the second heat conducting plate 17 are made of a material with a high thermal conductivity, such as copper.

[0055] After the high-pressure roller mill begins operation, heat is generated inside the bearing seat. This heat is transferred to the first working fluid in the heat-conducting tube 15 through the first heat-conducting plate 16. The first working fluid absorbs heat and vaporizes, causing the air pressure in the heat-conducting tube 15 to increase, thereby driving the second heat-conducting plate 17 to move. The second heat-conducting plate 17 can then drive the heat pipe 13 to move, causing the condensing end of the heat pipe 13 to move outside the third seat body 3 or the fourth seat body 4. The heat pipe 13 can then quickly transfer the heat inside the bearing seat to the outside, achieving good heat dissipation from the bearing seat. After the high-pressure roller mill stops operating, the temperature inside the bearing seat gradually decreases, the first working fluid gradually cools and liquefies, the air pressure in the heat-conducting tube 15 decreases, and the external air pressure pushes the heat pipe 13 and the second heat-conducting plate 17 toward the first heat-conducting plate 16, causing the heat pipe 13 to return to its initial position.

[0056] An arcuate mating surface is provided on the outer side of the second heat conducting plate 17 , and the heat pipe 13 fits in the mating surface. The arcuate mating surface can increase the contact area between the second heat conducting plate 17 and the heat pipe 13 , thereby improving the heat transfer speed.

[0057] The first mounting hole and the second mounting hole include a bearing mounting section and a retaining ring mounting section provided at both ends of the bearing mounting section. The bearing mounting section is used to mount the bearing, and the retaining ring mounting section is used to mount the retaining ring. The retaining ring is used to axially position the bearing. The cross-sectional view after the roller is mounted on the bearing seat is as follows: Figure 6 As shown, there is a sealed cavity between the inner circumference of the retaining ring and the roller. After assembly, lubricating oil can be injected into the sealed cavity to reduce bearing wear. Due to the high load of the high-pressure roller machine and the high temperature inside the bearing seat, the lubricating oil is easily oxidized and thermally decomposed, producing colloid and carbon deposits. These colloids and carbon deposits easily adhere to the bearings and accelerate bearing wear.

[0058] In order to reduce the adverse effects caused by gum and carbon deposition, the collecting groove 18 and the first filter plate 19 are arranged at the inner wall bottom of the third seat body 3 and the fourth seat body 4, the lower end of the first filter plate 19 extends into the collecting groove 18, the collecting groove 18 is divided into a liquid inlet cavity and a liquid outlet cavity which are communicated at the bottom, the upper end of the liquid outlet cavity is provided with the second filter plate 26, and a plurality of filter holes are arranged on the first filter plate 19 and the second filter plate 26.

[0059] The roller is installed by using a self-aligning bearing, when the roller rotates, the inner ring of the self-aligning bearing is driven to rotate, and the rotation of the inner ring of the bearing can drive the lubricating oil in the sealing cavity to move, and the movement direction of the lubricating oil is consistent with the rotation direction of the roller. Figure 7 When the roller rotates in the direction a, the lubricating oil also rotates in the direction a. When the lubricating oil moves to the first filter plate 19, the generated gum, carbon and other impurities are blocked by the first filter plate 19 and fall into the liquid inlet cavity, so that the gum and carbon are filtered and collected. Part of the lubricating oil also enters the collecting groove 18 and then is discharged from the second filter plate 26. The first filter plate 19 and the second filter plate 26 filter at the same time, the filtering area is increased, and when the lubricating oil enters the liquid outlet cavity from the liquid inlet cavity, the impurities can be driven to enter the liquid outlet cavity. After the impurities enter the liquid outlet cavity, it is difficult for them to move out of the collecting groove 18 again, so that the impurities are effectively filtered and collected.

[0060] The first seat body 1 and the second seat body 2 are connected with the hydraulic cylinder and the base, and are inconvenient to disassemble, while the third seat body 3 and the fourth seat body 4 are not connected with other parts of the high-pressure roller mill, and are lighter in weight and easy to disassemble. Therefore, the filtering and collecting mechanism for filtering and collecting gum, carbon and other impurities is arranged on the third seat body 3 and the fourth seat body 4. After the equipment runs for a period of time, the third seat body 3 and the fourth seat body 4 can be disassembled, and the first filter plate 19 and the collecting groove 18 can be cleaned.

[0061] The present application can filter the impurities generated in the bearing seat, clean the impurities more timely, reduce the deposition rate of the impurities on the bearing, delay the wear of the bearing, and reduce the frequency of replacing and cleaning the bearing.

[0062] Since the gum and carbon are easy to adhere to the first filter plate 19, the filter holes of the first filter plate 19 are blocked. In order to slow down the blockage of the first filter plate 19, the first filter plate 19 is arranged in a downwardly inclined manner from the liquid inlet cavity to the liquid outlet cavity, and the impurities filtered by the first filter plate 19 are located on the lower surface of the first filter plate 19. When the lubricating oil flows, the impurities are more easily washed into the collecting groove 18.

[0063] In addition, the first filter plate 19 is provided below with an upper cross bar 21, a lower cross bar 22 and a plurality of scrapers 23, one end of the upper cross bar 21 and the lower cross bar 22 is fixed to the inner wall of the third seat body 3 or the fourth seat body 4, the upper end of the scraper 23 is sleeved on the upper cross bar 21 and is in sliding fit with the upper cross bar 21, the lower end of the scraper 23 is sleeved on the lower cross bar 22 and is in sliding fit with the lower cross bar 22, and the side edge of the scraper 23 contacts the lower surface of the first filter plate 19, two adjacent scrapers 23 are connected through a connecting rod 24, and the scraper 23 located at the edge is connected to the inner wall of the third seat body 3 or the fourth seat body 4 through a heated elongation element 25, and the extension direction of the heated elongation element 25 is consistent with the length direction of the upper cross bar 21.

[0064] The heated elongation element 25 can adopt a structure similar to a thermal expansion mechanism, or a cylindrical air bag, a liquid with a boiling point of about 40 degrees Celsius is arranged in the air bag, after the high-pressure roller mill is started, the temperature of the lubricating oil gradually rises, the liquid in the air bag gradually vaporizes, the air bag expands, and the air bag drives each scraper 23 to move along the upper cross bar 21 and the lower cross bar 22, and the side edge of the scraper 23 can scrape off the impurities adhered to the lower surface of the first filter plate 19; when the high-pressure roller mill stops running, the temperature of the lubricating oil gradually decreases, the liquid in the air bag gradually liquefies, the air bag contracts, and drives the scraper 23 to move reversely, and the impurities adhered to the lower surface of the first filter plate 19 are scraped off again. When the high-pressure roller mill is started and stopped each time, the scraper 23 can scrape off the impurities adhered to the lower surface of the first filter plate 19, so that the filter holes of the first filter plate 19 are prevented from being quickly blocked, thereby reducing the frequency of cleaning the first filter plate 19.

[0065] In order to facilitate the installation of the above-mentioned filter collecting mechanism, installation windows can be formed in the side walls of the third seat body 3 and the fourth seat body 4, and a detachable mounting block is arranged in the installation window, the collecting groove 18, the upper cross bar 21, the lower cross bar 22 and the heated elongation element 25 are all mounted on the inner side wall of the mounting block, the mounting block can be first disassembled, the collecting groove 18, the upper cross bar 21, the lower cross bar 22 and the heated elongation element 25 are mounted on the mounting block, and then the roller is assembled, after the assembly is completed, the mounting block is mounted into the installation window. A sealing structure can be arranged between the mounting block and the installation window to prevent oil leakage.

[0066] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
