Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bearing lubrication technology, specifically a uniform lubrication device for cylindrical roller bearings. Background Technology
[0002] Cylindrical roller bearings consist of an inner ring, outer ring, cylindrical rollers, cage, and seals. Due to their high radial load capacity, low coefficient of friction, and ability to adapt to certain axial displacements, they are widely used in various industrial fields. After prolonged use, the lubrication function of bearings decreases, requiring the application of lubricating oil to restore its function and extend its service life. Existing bearing lubrication devices involve manually placing the bearing on a workbench and visually aligning it with the oil filler port. This leads to misalignment between the oil filler port and the bearing, resulting in uneven lubrication and even oil being applied outside the bearing, causing lubrication waste. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a uniform lubrication device for cylindrical roller bearings, which solves the problem that existing bearing lubrication devices require manual placement of the bearing on the worktable and visual alignment of the bearing with the oil inlet, resulting in a misalignment between the oil inlet and the bearing, uneven application of lubricating oil, and even application of lubricating oil outside the bearing, causing lubricating oil waste.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a cylindrical roller bearing uniform lubrication device, comprising a worktable, an annular groove at the center of the top of the worktable, a rotating disk rotatably connected inside the annular groove, a motor at the bottom of the worktable with its output end fixedly connected to the rotating disk, a mounting block fixedly installed at the center of the top of the rotating disk, a rotating gear rotatably connected inside the mounting block via a bearing, fixed racks slidably connected through the inner walls on both sides of the mounting block, and the two fixed racks meshing with the rotating gear, a threaded rod fixedly installed through the mounting block at the top of the rotating gear, and a rotating head fixedly installed at the top of the threaded rod;
[0005] The threaded rod is threadedly connected to a fixing nut on the surface of the top of the mounting block. The outer ring of the rotating disk is symmetrically provided with arc plates. A clamp is fixedly connected to the inner circular surface of the arc plate, and the clamp is slidably connected to the rotating disk. Connecting plates are symmetrically fixedly installed on both sides of the outer circular surface of the rotating disk, and the connecting plates are slidably connected to the arc plates. A guide rod is fixedly connected between the two connecting plates on the same side, and the two ends of the guide rod are slidably connected to the surface of the arc plate. A return spring is sleeved on the surface of the guide rod between the arc plate and the connecting plate.
[0006] As a further embodiment of this utility model: an electric telescopic rod is fixedly installed on one side of the workbench, and a top seat is fixedly installed on the top of the electric telescopic rod.
[0007] As a further embodiment of this utility model: a mounting bracket is slidably connected through the surface of the top seat, and rectangular grooves are symmetrically provided on both sides of the top seat.
[0008] As a further embodiment of this utility model: the mounting bracket has symmetrical through-threaded connection of clamping studs on both sides, and a rotating plate is fixedly installed at one end of the clamping studs located on the outer side of the mounting bracket.
[0009] As a further embodiment of this utility model: the end of the clamping stud located inside the mounting bracket is rotatably connected to a clamping block via a pin, and the clamping block corresponds to the position of the rectangular groove.
[0010] As a further embodiment of this utility model: an oil tank is fixedly installed at the bottom of the mounting bracket, and a sponge-soaked oil brush is fixedly installed at the bottom of the oil tank.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This cylindrical roller bearing uniform lubrication device, by setting a fixed rack and chuck, pulls two arc plates to place the bearing on a rotating disk. When the arc plates are released, the two arc plates move towards the bearing under the action of the return spring, so that the chuck is pressed against the bearing surface to clamp and fix the outer ring of the bearing. Then, the top seat is rotated to drive the threaded rod to rotate, so that the rotating gear rotates and pushes the two fixed racks against the inner ring of the bearing. Tightening the fixing nut prevents the threaded rod from rotating easily, thereby fixing the bearing on the surface of the rotating disk. This prevents the bearing from shifting when applying lubricating oil to the bearing, allowing the lubricating oil to be evenly applied to the bearing.
[0013] 2. This cylindrical roller bearing uniform lubrication device, by setting up a clamping block and a mounting bracket, pushes the mounting bracket to position the oil tank above the bearing. Rotating the rotating plate causes the clamping stud to push the clamping block to fit tightly into the rectangular groove, fixing the mounting bracket so that it will not move easily. Controlling the electric telescopic rod to descend causes the sponge-soaked oil brush to fit tightly against the top of the bearing, thereby achieving the application of lubricating oil to bearings of different models.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a cylindrical roller bearing uniform lubrication device, including a worktable 1, an annular groove 2 at the center of the top of the worktable 1, a rotating disk 3 rotatably connected inside the annular groove 2, a motor 10 at the bottom of the worktable 1, and the output end of the motor 10 fixedly connected to the rotating disk 3, a mounting block 4 fixedly installed at the center of the top of the rotating disk 3, a rotating gear 5 rotatably connected inside the mounting block 4 via a bearing, fixed racks 9 slidably connected through the inner walls on both sides of the mounting block 4, and the two fixed racks 9 mesh with the rotating gear 5, a threaded rod 6 fixedly installed through the mounting block 4 at the top of the rotating gear 5, and a rotating head 7 fixedly installed at the top of the threaded rod 6, by twisting the rotating head 7 to rotate the threaded rod 6, driving the rotating gear 5 to rotate, thereby pushing the two fixed racks 9 out of the mounting block 4 and tightly pressing them against the inner ring of the bearing, thus completing the fixation of the inner ring of the bearing.
[0020] A threaded rod 6 is threadedly connected to a fixing nut 8 on the surface of the mounting block 4. A circular arc plate 11 is symmetrically provided on the outer ring of the rotating disk 3. A chuck 12 is fixedly connected to the inner circular surface of the circular arc plate 11 and is slidably connected to the rotating disk 3. A connecting plate 15 is symmetrically fixedly installed on both sides of the outer circular surface of the rotating disk 3 and is slidably connected to the circular arc plate 11. A guide rod 13 is fixedly connected between the two connecting plates 15 on the same side and is slidably connected to the surface of the circular arc plate 11 at both ends. A return spring 14 is sleeved on the surface of the guide rod 13 between the circular arc plate 11 and the connecting plate 15. By providing the chuck 12, the two circular arc plates 11 are pulled to compress the return spring 14. When the bearing is placed on the rotating disk 3, the circular arc plate 11 is released. Under the return spring action of the return spring 14, the chuck 12 is pressed tightly against the outer ring of the bearing, thereby completing the fixation of the outer ring of the bearing.
[0021] An electric telescopic rod 16 is fixedly installed on one side of the workbench 1, and a top seat 17 is fixedly installed on the top of the electric telescopic rod 16. By using the electric telescopic rod 16, the electric telescopic rod 16 is controlled to descend so that the sponge-soaked oil brush 20 at the bottom of the oil tank 19 is attached to the top of the bearing to complete the application of lubricating oil to the bearing.
[0022] The top surface of the top seat 17 is slidably connected to the mounting bracket 18. The top seat 17 has rectangular grooves 24 symmetrically arranged on both sides. By providing the mounting bracket 18, the movable mounting bracket 18 drives the oil tank 19 to move and align with the top surface of the bearing, so that the device can lubricate bearings of various sizes.
[0023] The mounting bracket 18 has symmetrical through-threaded clamping studs 22 on both sides. A rotating plate 21 is fixedly installed at the outer end of the clamping stud 22 on the mounting bracket 18. A clamping block 23 is rotatably connected to the inner end of the clamping stud 22 on the mounting bracket 18 via a pin. The clamping block 23 is positioned corresponding to the rectangular groove 24. By providing the clamping stud 22, the rotating plate 21 is twisted to rotate the clamping stud 22, which moves the clamping block 23 toward the inside of the rectangular groove 24, so that the clamping block 23 is pressed against the rectangular groove 24, thereby preventing the mounting bracket 18 from moving easily on the top seat 17.
[0024] An oil tank 19 is fixedly installed at the bottom of the mounting bracket 18, and a sponge-soaked oil brush 20 is fixedly installed at the bottom of the oil tank 19. With the sponge-soaked oil brush 20 attached to the top of the bearing, the lubricating oil in the oil tank 19 wets the sponge-soaked oil brush 20, and the bearing rotates on the rotating disk 3, thereby achieving uniform lubrication of the bearing.
[0025] The working principle of this utility model is as follows:
[0026] Pull the two arc plates 11 outwards towards the workbench 1 to compress the return spring 14. Then place the bearing on the rotating disk 3, release the arc plates 11, and under the return spring 14's restoring action, move the chuck 12 towards the bearing surface to fix the bearing's outer ring. Then turn the rotating head 7 to drive the threaded rod 6 to rotate, thereby causing the rotating gear 5 to rotate. This causes the fixed rack 9 to push out the mounting block 4 and press it against the bearing's inner ring, fixing the bearing's inner ring. Move the mounting bracket 18 to align the sponge-soaked brush 20 with the bearing's top. Twist the rotating plate 21 to cause the clamping stud 22 to move the clamping block 23 into the rectangular groove 24, ultimately pressing the clamping block 23 against the rectangular groove 24, preventing the mounting bracket 18 from easily moving on the top seat 17. Then control the electric telescopic rod 16 to descend so that the sponge-soaked brush 20 presses against the bearing's top. Start the motor 10 to rotate the rotating disk 3, causing the bearing to rotate and providing uniform lubrication.
