Description

Technical Field

[0001] This invention relates to the field of bearing cleaning technology, and more specifically to a cleaning device for rolling bearings. Background Technology

[0002] Rolling bearings convert the sliding friction between the rotating shaft and the bearing housing into rolling friction, thereby reducing wear. During operation, rotating parts are supported by the rolling motion between the main components. When axial or radial loads are applied to the bearing, the rolling elements displace under the load, accumulating displacement and forming elastic contact with the inner and outer rings, thus ensuring normal bearing operation. A search reveals that Chinese patent CN108636882A discloses a bearing cleaning device; however, this patented technology has the following drawbacks:

[0003] Before cleaning, the bearings are stacked in the drain basket. During cleaning, the spray mechanism sprays water towards the drain basket to clean the bearings inside. However, since the bearings in the drain basket are stacked, most of the water sprayed by the spray mechanism can only act on the upper bearings in the drain basket. The water cannot penetrate and act on the lower bearings. Even if the water can flow through the lower bearings, it cannot generate enough impact force to clean the lower bearings.

[0004] Therefore, it is necessary to provide a cleaning device for rolling bearings to address the above-mentioned problems. Summary of the Invention

[0005] Therefore, it is necessary to provide a cleaning device for rolling bearings to address the aforementioned technical problems.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a cleaning device for rolling bearings, including a worktable, a cleaning tank, a reciprocating lifting mechanism, and a lateral swaying mechanism on the worktable. The reciprocating lifting mechanism includes a lifting drive component, a bracket, and two transmission rods. The lifting drive component is located on the top of the cleaning tank, and the bracket is located inside the cleaning tank. The two transmission rods are symmetrically arranged between the lifting drive component and the bracket. Each transmission rod includes a limiting rod and a following rod. The limiting rod is slidably connected to the cleaning tank in the vertical direction. The upper end of the limiting rod is connected to the lifting drive component, and the lower end of the limiting rod is provided with a horizontal strip seat. The follower rod is vertically positioned below the strip seat. The upper end of the follower rod is equipped with a slider that slides horizontally with the strip seat. The bracket is connected to the two follower rods. A drain basket is rotatably mounted on the bracket. The cleaning tank is equipped with a spray mechanism and a rotary drive mechanism.

[0010] Furthermore, the lifting drive component includes a No. 1 motor, a No. 1 drive disc, a No. 1 connecting rod, and a No. 1 connecting plate. Two symmetrical No. 1 limit sleeves are fixed on the top of the cleaning tank, each No. 1 limit sleeve being vertical. The upper ends of the two limit rods pass through the two No. 1 limit sleeves respectively. The No. 1 connecting plate is fixedly connected to the upper ends of the two limit rods. A support platform is fixedly provided on the top of the cleaning tank. The No. 1 motor is horizontally fixed on the support platform. The No. 1 drive disc is coaxially fixedly connected to the output end of the No. 1 motor. The No. 1 drive disc is provided with a No. 1 stroke adjustment component, which includes a No. 1 translation block that translates radially along the No. 1 drive disc. One end of the No. 1 connecting rod is hinged to the No. 1 connecting plate, and the other end of the No. 1 connecting rod is hinged to the No. 1 translation block.

[0011] Furthermore, the first stroke adjustment component also includes a first threaded sleeve and a first screw. A first strip groove is formed on the first drive disk.

[0012] Furthermore, the translation drive component includes a second motor, a second drive disc, a second connecting rod, and a second connecting plate. Two symmetrical second limit sleeves are fixedly installed on one side of the cleaning tank. Each second limit sleeve is horizontal. One end of each of the two transverse rods passes through the two second limit sleeves. The second connecting plate is fixedly connected to the protruding ends of the two transverse rods. A mounting platform is fixedly installed on the worktable. The second motor is vertically fixed on the mounting platform. The second drive disc is coaxially fixed to the output end of the second motor. The second drive disc is equipped with a second stroke adjustment component, which includes a second translation block that translates radially along the second drive disc.

[0014] Furthermore, the spraying mechanism includes a water pipe and several inclined nozzles. The water pipe is horizontally fixed inside the cleaning tank. One end of the water pipe is a closed structure, and the other end is provided with a water inlet. Several nozzles are equidistantly distributed along the axial direction of the water pipe, and each nozzle is connected to the water pipe.

[0015] The beneficial effects of this invention compared to the prior art are:

[0016] Firstly, the cleaning of the rolling bearings by this device is divided into a first cleaning and a second cleaning. During the first cleaning, the lifting drive will drive the drain basket to move up and down repeatedly. At the same time, the drain basket will be driven to flip by the rotary drive mechanism during the rising process. Finally, the lifting and flipping of the drain basket will enable the spraying mechanism to thoroughly clean the rolling bearings in the drain basket.

[0017] Secondly, during the second cleaning process, the water in the cleaning tank is no longer turbulent due to the lifting and rotating of the drain basket. As a result, when the rolling bearing is driven by the drain basket to move laterally back and forth in the cleaning tank, the oil stains washed out in the first cleaning will gradually float on the water surface, and the rolling bearing moving back and forth will wash out the residual oil stains by impacting the water.

[0018] Third, before the cleaning work, the lifting stroke of the drain basket can be adjusted by sliding the first sliding block, so that the drain basket can be flipped once by the rotary drive mechanism during the rising process. The closer the first sliding block is to the outer edge of the first drive plate, the greater the lifting stroke of the drain basket. Attached Figure Description

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] refer to Figures 1 to 19 The rolling bearing cleaning device shown includes a worktable 1, on which a cleaning tank 2, a reciprocating lifting mechanism 3, and a lateral swaying mechanism 4 are mounted. The reciprocating lifting mechanism 3 includes a lifting drive component, a bracket, and two transmission rods. The lifting drive component is located on top of the cleaning tank 2, and the bracket is located inside the cleaning tank 2. The two transmission rods are symmetrically arranged between the lifting drive component and the bracket. Each transmission rod includes a limiting rod 5 and a follower rod 6 (e.g., a limit rod 5 and a follower rod 6). Figure 7As shown), the limiting rod 5 is slidably connected to the cleaning tank 2 in the vertical direction. The upper end of the limiting rod 5 is connected to the lifting drive component. The lower end of the limiting rod 5 is provided with a horizontal strip seat 7. The follower rod 6 is vertically located below the strip seat 7. The upper end of the follower rod 6 is provided with a slider 8 that is slidably connected to the strip seat 7 in the horizontal direction. The bracket is connected to the two follower rods 6. A drain basket 9 is rotatably mounted on the bracket. The cleaning tank 2 is provided with a spraying mechanism and a rotary drive mechanism. The rotary drive mechanism is connected to the drain basket 9. The top of the drain basket 9 is an open structure. A rolling bearing is placed inside the drain basket 9. A hollow pressure plate 10 is fixed on the opening of the drain basket 9 (e.g., Figure 10 As shown), the lateral swaying mechanism 4 includes a translation drive and two symmetrical lateral rods 11. One end of each lateral rod 11 is connected to the translation drive, and the other end of each lateral rod 11 is provided with a circular sleeve 12 sleeved on the follower rod 6.

[0041] First, place the rolling bearing to be cleaned into the drain basket 9. Then, fix the perforated pressure plate 10 to the opening of the drain basket 9. The perforated pressure plate 10 presses the rolling bearing tightly into the drain basket 9 and prevents it from falling out. The cleaning of the rolling bearing is divided into a first cleaning and a second cleaning. The first cleaning process is as follows: water is sprayed towards the drain basket 9 by the spray mechanism, thus cleaning the rolling bearing in the drain basket 9 through water rinsing. During the spraying process, the lifting drive will synchronously drive the two transmission rods to rise and fall. When the transmission rods rise and fall, the brackets connected to the two follower rods 6 will drive the drain basket 9 to reciprocate. During the reciprocating rise and fall of the drain basket 9, the rotation drive mechanism will drive the drain basket 9 to rotate, so that the rolling bearing in the drain basket 9 can be thoroughly cleaned by the spray mechanism. After the first cleaning, the rolling bearing will enter the second cleaning. Since the spray mechanism sprays water towards the drain basket 9 during the first cleaning process, the water level in the cleaning tank 2 will gradually rise. When the rolling bearing enters the second cleaning cycle, the water level in the cleaning tank 2 will submerge the drain basket 9. The second cleaning process is as follows: the spray mechanism and the lifting drive stop working. At this time, the translation drive will synchronously drive the two transverse rods 11 to reciprocate. The two transverse rods 11 will drive the bracket to reciprocate through the two follower rods 6 respectively. Finally, the drain basket 9 will be driven to reciprocate within the cleaning tank 2. During this process, the water in the cleaning tank 2 will no longer be turbulent due to the lifting and rotating of the drain basket 9. When the rolling bearing is driven by the drain basket 9 to move laterally back and forth in the cleaning tank 2, the oil sludge washed out in the first round of cleaning will gradually float to the surface of the water. The rolling bearing moving back and forth washes out the residual oil sludge by impact with the water. Finally, the rolling bearing will be cleaned after the first and second rounds of cleaning. After the oil sludge floats to the surface of the water, it can be extracted through the external oil suction pipe (not shown in the figure). Therefore, the rolling bearing will not be secondary contaminated by the oil sludge on the water surface during the removal process.

[0042] To facilitate the placement of the rolling bearing within the drain basket 9, the following features are provided:

[0043] The drain basket 9 has vertical angle steel 13 formed on each of its four corners. The drain basket 9 has several horizontal hollowed-out support plates 14. The four corners of each hollowed-out support plate 14 correspond to the four angle steel 13. The hollowed-out pressure plate 10 has vertical plates 15 formed on each of its four corners. The four vertical plates 15 correspond to the four angle steel 13. Each vertical plate 15 has a bolt 16 connected to the angle steel 13.

[0044] When placing the rolling bearing into the drain basket 9, first place the rolling bearing flat on top of the hollowed-out support plate 14, and then place the hollowed-out support plate 14 downward into the drain basket 9. During this process, each corner of the hollowed-out support plate 14 will slide down along the corresponding angle steel 13. Finally, several hollowed-out support plates 14 will be stacked vertically in the drain basket 9. After all the hollowed-out support plates 14 have been placed, place the hollowed-out pressure plate 10 flat on the top layer of rolling bearing, and then use bolts 16 to fix the upright plate 15 on the hollowed-out pressure plate 10 to the corresponding angle steel 13. The hollowed-out pressure plate 10 presses the rolling bearing in the drain basket 9 tightly and prevents the rolling bearing from falling out of the drain basket 9.

[0045] To demonstrate the specific structure of the bracket, the following features were incorporated:

[0046] Both sides of the drain basket 9 are fixed with vertical mounting plates 17, and each mounting plate 17 has a horizontally oriented pivot 18 (e.g., ...). Figure 13 As shown), the bracket includes two symmetrical hangers 19. Each hanger 19 has a vertical panel 20 formed on it. A bearing 21 is embedded on both sides of the panel 20. Each rotating shaft 18 passes through the corresponding panel 20 and is connected to the two corresponding bearings 21. The lower ends of the two follower rods 6 are fixedly connected to the two hangers 19 respectively.

[0047] The drain basket 9 rotates between two hangers 19 via the pivots 18 on both sides. When the lifting drive is activated, the drain basket 9 is driven to rotate by the rotary drive mechanism during its ascent, thereby enabling the spraying mechanism to thoroughly clean the rolling bearings inside the drain basket 9.

[0048] To demonstrate the specific structure of the rotary drive mechanism, the following features are provided:

[0049] The rotary drive mechanism includes two sets of symmetrically arranged follower rotating components on both sides of the drain basket 9. Each set of follower rotating components includes a rotating frame 22, a turntable 23, a gear ring 24, a rack 25, and a one-way drive component. The rotating frame 22 is coaxially and fixedly connected to the rotating shaft 18. A second bearing 26 is embedded in the turntable 23. The rotating shaft 18 passes through the turntable 23 and is connected to the second bearing 26. The gear ring 24 is fixedly sleeved on the turntable 23. The rack 25 is vertically fixedly connected to the corresponding transverse moving rod 11, and the gear ring 24 meshes with the rack 25. The one-way drive component includes a ratchet ring 27 and several elastic pawls 28. The ratchet ring 27 is coaxially and fixedly connected to the turntable 23 (e.g., ...). Figure 15 As shown, several elastic pawls 28 are evenly distributed along the circumference on the rotating frame 22, and each elastic pawl 28 meshes with the ratchet ring 27.

[0050] When the lifting drive is working, each limit rod 5 will be driven to rise and fall. Since the slider 8 at the upper end of the follower rod 6 is slidably connected to the strip seat 7 at the lower end of the limit rod 5, and the sliding direction of the slider 8 is horizontal, when the limit rod 5 rises and falls, the follower rod 6 will follow the displacement of the limit rod 5. Thus, the two follower rods 6 will synchronously drive the two hangers 19 to rise and fall. During the rising and falling of the hangers 19, the transverse rod 11 will not move. Therefore, the rack 25 fixed to the transverse rod 11 is in a fixed state at this time. When the hanger 19 rises, the toothed ring 24 will roll on the rack 25. Thus, the turntable 23 will be driven to rotate by the rack 25. After the turntable 23 rotates, the ratchet ring 27 on the turntable 23 will drive the rotating frame 22 to rotate through several elastic pawls 28. The rotating frame 22 will drive the rotating shaft 18 to rotate. Finally, the entire drain basket 9 will be driven to flip over. When the hanger 19 descends, the turntable 23 is driven to rotate in the opposite direction by the rack 25. At this time, several elastic pawls 28 will slide over the ratchet ring 27, and the rotating shaft 18 will not be driven to rotate. In summary, when the drain basket 9 rises, it will also flip over. When the drain basket 9 descends, it will not rotate. Finally, the flipping of the drain basket 9 during its ascent allows the spraying mechanism to thoroughly clean the rolling bearings inside the drain basket 9. The fact that the drain basket 9 does not flip during its descent allows the spraying mechanism to continuously spray the rolling bearings inside the drain basket 9 for a period of time. After several cycles of spraying, the rolling bearings inside the drain basket 9 will be completely cleaned. Furthermore, the drain basket 9 can rotate in one direction via a one-way drive component. Therefore, after cleaning, the tilted drain basket 9 can be manually straightened to facilitate the removal of the rolling bearings inside the drain basket 9.

[0051] To demonstrate the specific structure of the lifting drive component, the following features were set:

[0052] The lifting drive components include a No. 1 motor 29, a No. 1 drive disc 31, a No. 1 connecting rod 32, and a No. 1 connecting plate 33. Two symmetrically positioned No. 1 limit sleeves 34 are fixed to the top of the cleaning tank 2 (e.g., Figure 16 As shown), each of the first limiting sleeves 34 is vertical, and the upper ends of the two limiting rods 5 pass through the two first limiting sleeves 34 respectively. The first connecting plate 33 is fixedly connected to the upper ends of the two limiting rods 5. The top of the cleaning tank 2 is fixedly equipped with a support platform 35 (as shown). Figure 4 As shown), motor 29 is horizontally fixed on support platform 35, and drive disk 31 is coaxially fixed to the output end of motor 29 (as shown). Figure 18 As shown), a first stroke adjustment component is provided on the first drive disk 31. The first stroke adjustment component includes a first translation block 36 that translates radially along the first drive disk 31. One end of the first connecting rod 32 is hinged to the first connecting plate 33, and the other end of the first connecting rod 32 is hinged to the first translation block 36.

[0053] When motor 29 starts, it drives drive disc 31 to rotate. Since each limit rod 5 is limited by limit sleeve 34, when drive disc 31 rotates, connecting rod 32 drives two limit rods 5 to rise and fall synchronously through connecting plate 33. Finally, limit rods 5 drive the entire drain basket 9 to rise and fall through follower rod 6. Before cleaning, the lifting stroke of drain basket 9 can be adjusted by sliding translation block 36, so that drain basket 9 can complete a flip through the rotation drive mechanism during the rising process. The closer translation block 36 is to the outer edge of drive disc 31, the greater the lifting stroke of drain basket 9.

[0054] To demonstrate how translation block 36 slides, the following features were set:

[0055] The first stroke adjustment component also includes a first threaded sleeve 37 and a first screw 38. A first strip groove 39 is formed on the first drive disk 31. The length direction of the first strip groove 39 is consistent with the radial direction of the first drive disk 31. The first translation block 36 slides in the first strip groove 39. The first screw 38 is rotatably mounted on the first drive disk 31. The axial direction of the first screw 38 is parallel to the sliding direction of the first translation block 36. The first threaded sleeve 37 is located in the first translation block 36. The first screw 38 passes through the first threaded sleeve 37 and is threadedly engaged with the first threaded sleeve 37.

[0056] The first translation block 36 is limited by the first strip groove 39. When it is necessary to drive the first translation block 36 to move, the first screw 38 is rotated. The first screw 38 will drive the first translation block 36 to move through the first threaded sleeve 37. When it is necessary to increase the lifting stroke of the drain basket 9, the first translation block 36 is adjusted to move towards the outer edge of the first drive disk 31. When it is necessary to reduce the lifting stroke of the drain basket 9, the first translation block 36 is adjusted to move towards the center of the first drive disk 31.

[0057] To demonstrate the specific structure of the translation drive component, the following features were set:

[0058] The translation drive component includes a second motor 40, a second drive disc 41, a second connecting rod 42, and a second connecting plate 43. Two symmetrical second limiting sleeves 44 are fixed on one side of the cleaning tank 2 (e.g., Figure 16 As shown), each of the second limiting sleeves 44 is horizontal. One end of each of the two transverse rods 11 passes through the two second limiting sleeves 44 respectively. The second connecting plate 43 is fixedly connected to the protruding ends of the two transverse rods 11. A mounting platform 45 is fixedly provided on the workbench 1. The second motor 40 is vertically fixed on the mounting platform 45. The second drive disk 41 is coaxially fixedly connected to the output end of the second motor 40. The second drive disk 41 is provided with a second stroke adjustment component. The second stroke adjustment component includes a second translation block 46 that translates radially along the second drive disk 41. One end of the second connecting rod 42 is hinged to the second connecting plate 43, and the other end of the second connecting rod 42 is hinged to the second translation block 46.

[0059] When the second motor 40 starts, it will drive the second drive plate 41 to rotate. Since each transverse rod 11 is limited by the second limit sleeve 44, when the second drive plate 41 rotates, the second connecting rod 42 will drive the two transverse rods 11 to move laterally through the second connecting plate 43. The transverse rods 11 will drive the follower rod 6 to move horizontally through the circular sleeve 12. During this process, the slider 8 located at the upper end of the follower rod 6 will slide in the strip seat 7. After the follower rod 6 moves horizontally, the two follower rods 6 will drive the drain basket 9 to move back and forth horizontally in the cleaning box 2. Before the cleaning work, the transverse stroke of the drain basket 9 can be adjusted by sliding the second translation block 46 to prevent the transversely moving drain basket 9 from colliding with the cleaning box 2.

[0060] To demonstrate how translation block 46 slides, the following features were set:

[0061] The second stroke adjustment component also includes a second threaded sleeve 47 and a second screw 48. A second strip groove 49 is formed on the second drive disk 41. The length direction of the second strip groove 49 is consistent with the radial direction of the second drive disk 41. The second translation block 46 slides in the second strip groove 49. The second screw 48 is rotatably mounted on the second drive disk 41. The axial direction of the second screw 48 is parallel to the sliding direction of the second translation block 46. The second threaded sleeve 47 is located in the second translation block 46. The second screw 48 passes through the second threaded sleeve 47 and is threadedly engaged with the second threaded sleeve 47.

[0062] The second translation block 46 is limited by the second strip groove 49. When it is necessary to drive the second translation block 46 to move, the second screw 48 is rotated. The second screw 48 will drive the second translation block 46 to move through the second threaded sleeve 47. When it is necessary to increase the lateral travel of the drain basket 9, the displacement of the second translation block 46 toward the outer edge of the second drive disk 41 is adjusted. When it is necessary to reduce the lateral travel of the drain basket 9, the displacement of the second translation block 46 toward the center of the second drive disk 41 is adjusted.

[0063] To demonstrate the specific structure of the spraying mechanism, the following features were incorporated:

[0064] The sprinkler system includes a water pipe 50 and several inclined nozzles 51 (e.g., Figure 19 As shown), the water pipe 50 is horizontally fixed inside the cleaning tank 2. One end of the water pipe 50 is a closed structure, and the other end is provided with a water inlet 52. Several nozzles 51 are equidistantly distributed along the axial direction of the water pipe 50, and each nozzle 51 is connected to the water pipe 50.

[0065] In actual use, the inlet 52 is connected to an external water source. Water flows into the water pipe 50 through the inlet 52. The water entering the water pipe 50 will be sprayed onto the drain basket 9 through several nozzles 51.

[0066] Working principle:

[0067] First, place the rolling bearing to be cleaned into the drain basket 9. Then, fix the perforated pressure plate 10 to the opening of the drain basket 9. The perforated pressure plate 10 presses the rolling bearing tightly into the drain basket 9 and prevents it from falling out. The cleaning of the rolling bearing is divided into a first cleaning and a second cleaning. The first cleaning process is as follows: water is sprayed towards the drain basket 9 by the spray mechanism, thus cleaning the rolling bearing in the drain basket 9 through water rinsing. During the spraying process, the lifting drive will synchronously drive the two transmission rods to rise and fall. When the transmission rods rise and fall, the brackets connected to the two follower rods 6 will drive the drain basket 9 to reciprocate. During the reciprocating rise and fall of the drain basket 9, the rotation drive mechanism will drive the drain basket 9 to rotate, so that the rolling bearing in the drain basket 9 can be thoroughly cleaned by the spray mechanism. After the first cleaning, the rolling bearing will enter the second cleaning. Since the spray mechanism sprays water towards the drain basket 9 during the first cleaning process, the water level in the cleaning tank 2 will gradually rise. When the rolling bearing enters the second cleaning cycle, the water level in the cleaning tank 2 will submerge the drain basket 9. The second cleaning process is as follows: the spray mechanism and the lifting drive stop working. At this time, the translation drive will synchronously drive the two transverse rods 11 to reciprocate. The two transverse rods 11 will drive the bracket to reciprocate through the two follower rods 6 respectively. Finally, the drain basket 9 will be driven to reciprocate within the cleaning tank 2. During this process, the water in the cleaning tank 2 will no longer be turbulent due to the lifting and rotating of the drain basket 9. When the rolling bearing is driven by the drain basket 9 to move laterally back and forth in the cleaning tank 2, the oil sludge washed out in the first round of cleaning will gradually float to the surface of the water. The rolling bearing moving back and forth washes out the residual oil sludge by impact with the water. Finally, the rolling bearing will be cleaned after the first and second rounds of cleaning. After the oil sludge floats to the surface of the water, it can be extracted through the external oil suction pipe (not shown in the figure). Therefore, the rolling bearing will not be secondary contaminated by the oil sludge on the water surface during the removal process.
