Description

Technical Field

[0001] The utility model relates to the technical field of roller bearings, in particular to a tapered roller bearing used for miniaturized equipment. Background Art

[0002] Double-row tapered roller bearings are an important type of rolling bearings. Due to their high load-bearing capacity, good rigidity, and suitability for bearing both radial and axial loads, they are widely used in industrial machinery, automobiles, aerospace, and other fields. They consist of two inner rings, two outer rings, tapered rollers, and cages. The rollers on the inner and outer rings are arranged in pairs to form a double-row structure, which can provide greater load-bearing capacity.

[0003] A Chinese patent with publication number CN220396271U discloses a double-row tapered roller bearing, which relates to the field of bearing technology, including: an outer ring and an inner ring, two inner rings are provided, a retaining frame is provided on the inner side of the retaining frame, a roller body is provided on the inner side of the retaining frame, a plurality of roller bodies are provided, and the plurality of roller bodies are evenly distributed on the retaining frame; an oil filling hole is provided on one side of the outer ring, and an oil filling assembly is provided on one side of the outer ring located at the oil filling hole; the present application has the beneficial effects of high load-bearing capacity, good rigidity, convenient lubrication and maintenance, effective sealing protection and stable fixed support, making it suitable for high-speed and heavy-load applications, and providing reliable and durable bearing performance.

[0004] However, the above-mentioned disclosed scheme has the following shortcomings: the above-mentioned device needs to oil the bearing at regular intervals during use to ensure the stability of the bearing. Bearings used in miniaturized equipment often have the characteristics of higher rotation speed but lower load. However, higher rotation causes the internal temperature of the bearing to rise faster, thereby increasing the maintenance frequency of oiling and lubrication. However, the effect of oiling and lubricating of the above-mentioned device does not last long each time, which increases the difficulty of use for staff. Utility Model Content

Compared with the traditional device which only lubricates oil through the metal surface, the device adopts an independent oil storage part to extend the refueling time of the device, thereby reducing the maintenance frequency of the staff. The centrifugal force of the rotation can rotate the bristles from the oil storage part to the side of the drum through the centrifugal force when the drum rotates at high speed, thereby ensuring that the drum is in a lubricated state for a long time.

[0025] like Figure 1-Figure 5 As shown, the utility model proposes a tapered roller bearing for miniaturized equipment, comprising a wrapping portion 1, an inclined support member 12 and a rotating connecting rod 13;

[0026] A bottom plate 3 is provided at the bottom of the wrapping part 1; a rotatably connected cone part 2 is provided on the bottom plate 3; a through hole is provided at the center of the cone part 2, and a plurality of groups of grooves are provided on the side surface of the cone part 2, and a rotatably connected rotating shaft 5 is provided at an inclined top of the inner wall of the groove; a roller 4 is provided at the bottom of the rotating shaft 5; the side surface of the roller 4 protrudes from the inclined side surface of the cone part 2; an inclined support part 12 is provided at the bottom of the cone part 2, and the top of the inclined support part 12 is rotatably connected to the bottom of the roller 4; a rotating bracket 7 is provided on the inner wall of the cone part 2; a spring 14 is provided on the inner wall of the cone part 2; an oil storage part 6 is provided on the inner wall of the cone part 2; a rotatably connected swing shaft 8 is provided on the side surface of the rotating bracket 7; a rotating connecting rod 13 is provided on the side surface of the swing shaft 8; a counterweight 9 is provided on the side surface of the rotating connecting rod 13; a rotatably connected rotating wheel 10 is provided on the end of the rotating connecting rod 13 away from the swing shaft 8; a plurality of groups of bristles 11 are provided on the side surface of the outer end surface of the rotating wheel 10, and the bristles 11 are in contact with the side surface of the oil storage part 6; the end of the spring 14 away from the cone part 2 is connected to the side surface of the rotating connecting rod 13.

[0027] The wrapping portion 1 includes an outer shell 101; a cover plate 102 is provided on the top of the outer shell 101, and multiple groups of mounting brackets 103 are provided on the outer end surface of the cover plate 102; the multiple groups of mounting brackets 103 are distributed around the side of the cover plate 102 at equal intervals in a circle, and positioning holes 104 are provided on the mounting brackets 103; the positioning holes 104 are provided with internal threads; a conical sleeve 105 is provided on the inner wall of the outer shell 101.

[0028] The inner diameter of the bottom plate 3 is smaller than that of the outer shell 101 . A rotating groove is provided on the top of the bottom plate 3 . A rotating protrusion is provided on the bottom of the cone 2 . The rotating groove is rotatably connected to the rotating protrusion. The diameter of the through hole at the center of the cone 2 is smaller than the inner diameter of the bottom plate 3 .

[0029] A rotation blocking member is provided inside the conical member 2 , and a side surface of the rotation blocking member contacts a side surface of the rotation connecting rod 13 .

[0030] A plurality of sets of rotating sleeves are arranged inside the cone part 2 , and the rotating sleeves are rotatably connected to the top of the rotating shaft 5 , and a gap exists between the bottom side of the drum 4 and the bottom of the groove of the cone part 2 .

[0031] The oil storage member 6 includes but is not limited to a sponge. There is a distance between the oil storage member 6 and the side surface of the drum 4 , and the bristles 11 are in contact and squeezed with the side surface of the oil storage member 6 .

[0032] A wear-resistant layer is provided on the inner wall side of the conical sleeve 105, and the bottom plate 3 and the cover plate 102 are connected to the top and bottom of the shell 101 by screws.

[0033] In this embodiment, the device can effectively improve the long-term stable rotation effect of the bearing. Compared with the traditional bearing structure, the device can store a large amount of lubricating oil inside the device through the structure of the oil storage part 6, so that the lubricating oil is evenly released during the use of the device, ensuring a long-term lubrication effect.

[0034] When the device is in working condition, the structure of the cover plate 102 and the mounting bracket 103 can facilitate the fixed connection between the outer end face of the device and the equipment, thereby avoiding the shaking of the bearing during the rotation process and ensuring the rotation stability. When the device is refueled and maintained, the oil filling bottle is inserted into the position between the tapered sleeve 105 and the roller 4, so that the lubricating oil enters the oil storage part 6 through the groove gap between the roller 4 and the side of the cone part 2. At this time, the surface of the roller 45 and the inside of the oil storage part 6 are filled with lubricating oil, and the bristles 11 are also filled with lubricating oil due to contact with the side of the oil storage part 6.

[0035] When the device is in high-speed rotation, the cone 2 rotates at high speed relative to the housing 104, and the cone 2 generates a large centrifugal force, so that the rotating connecting rod 13 rotates toward the drum 4. At this time, the spring 14 is in a stretched state, so that as the rotation speed of the cone 2 increases, the swing angle of the rotating connecting rod 13 gradually increases, thereby avoiding the rotating connecting rod 13 directly hitting the side of the drum 4 or the influence of gravity on the device when the device is used vertically.

[0036] When the rotating connecting rod 13 starts to swing, the bristles 11 adhere to the lubricating oil by contacting the side of the oil storage part 6. As the rotating connecting rod 13 swings, the bristles 11 contact the side of the roller 4, thereby achieving the refueling effect of the present device. Compared with the traditional refueling method, the lubricating oil in the oil storage part 6 has a smaller contact area with the air, thereby reducing the risk of lubricating oil oxidation. At the same time, as the rotation speed of the bearing increases and decreases, the side of the roller can be refueled intermittently, thereby always maintaining the rotational lubrication between the roller 4 and the tapered sleeve 105, effectively improving the service life of the present device. The structure of the counterweight 9 can effectively improve the effect of the rotating connecting rod 13 of the present device rotating with the centrifugal force, thereby ensuring that after the cone 2 reaches a certain rotation speed, the bristles 11 can contact the side of the roller 4. The structure of the rotating wheel 10 can make the bristles 11 rotate freely during the process of dipping in the lubricating oil, so that the bristles 11 in all directions can be used evenly, avoiding the problem of excessive wear of the bristles 11 in one direction.

[0037] Embodiment 2

[0038] like Figure 1-Figure 5 As shown, the utility model proposes a tapered roller bearing for miniaturized equipment. Compared with the first embodiment, in this embodiment, a seal is provided on the top of the shell 101, and the seal is connected to the bottom connection seam of the cover plate 102. The inner diameter of the cover plate 102 is smaller than the inner diameter of the outer shell 101, and the inner wall of the cover plate 102 is rotatably connected to the top of the cone 2.

[0039] The structure of the seal can reduce the dust from entering the internal structure of the device, thereby improving the use stability of the device, prolonging the time for the lubricating oil to become viscous, and increasing the long-term stable use time of the device.
