Description

Technical Field

[0001] The utility model relates to the technical field of bearing seats, in particular to a novel split vertical bearing seat. Background Art

[0002] The bearing seat is a component used to support and fix the bearing in mechanical equipment. Its main function is to provide a stable foundation to ensure that the bearing can work correctly, thereby supporting the rotating shaft or other mechanical components. In order to facilitate the disassembly and maintenance of the bearing, the bearing seat can be designed as a split structure.

[0003] As in the prior art, a Chinese patent with publication number CN113048153A discloses a stable split bearing seat with high-strength support, comprising a lower seat body, an upper seat body arranged above the lower seat body, and a locking device connecting the upper seat body and the lower seat body, wherein the locking device comprises a locking mechanism and a positioning mechanism, wherein: the locking mechanism is used to fasten the upper seat body and the lower seat body; the positioning mechanism comprises a positioning assembly, an ejection assembly, and a plug-in assembly connecting the positioning assembly and the ejection assembly, wherein: the positioning assembly is used to achieve rapid positioning between the upper seat body and the lower seat body.

[0004] Based on the above materials, it can be seen that in the prior art, the bearing seat is generally set to be split into upper and lower parts for easy disassembly operation. However, in actual use, the contact area between the bearing and the rotating shaft is limited, so the support effect for heavier bearings is poor, resulting in the rotating shaft being slightly deformed due to its own weight during use, causing vibration, affecting the overall service life. Utility Model Content

[0013] Preferably, an oil filling pipe is fixedly mounted on the upper surface of the upper sleeve, and four oiling nozzles are fixedly mounted on the lower surface of the upper sleeve.

[0014] Preferably, the position of the oiling nozzle corresponds to the position of the connecting bearing, and the oiling nozzle is connected to the oil filling pipe through the connecting pipe.

[0015] Preferably, a pressurized airbag connected to the connecting tube is fixedly mounted on the upper end thereof, and the pressurized airbag is located directly below the oil filling tube, and an up-and-down sliding telescopic structure is formed between the oil filling tube and the upper sleeve.

[0017] 1. The main part of the bearing seat (i.e. the mounting sleeve) is divided into two parts: the lower sleeve and the upper sleeve. The first fixing block and the second fixing block are fixedly installed on the sides of the lower sleeve and the upper sleeve respectively.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figure 1-Figure 2In order to achieve the purpose of split disassembly, this embodiment provides the following technical solutions, which specifically disclose: a mounting base 1 with threaded holes, and a mounting sleeve 2 is installed on the upper surface of the mounting base 1, a connecting bearing 3 is installed inside the mounting sleeve 2, and a rotating shaft 4 is installed inside the connecting bearing 3, the mounting sleeve 2 is divided into a lower sleeve 201 and an upper sleeve 202, and the lower sleeve 201 is fixedly connected to the mounting base 1, and a first fixing block 5 is fixedly installed on the side of the lower sleeve 201, and a second fixing block 6 is fixedly installed on the side of the upper sleeve 202, and the second fixing block 6 is fixedly connected to the first fixing block 5 by a fixing bolt 7.

[0032] When using the device, first use bolts to fix the mounting base 1 to the equipment, then install the connecting bearing 3 and the rotating shaft 4 in the mounting sleeve 2, and connect the rotating shaft 4 to the driving device. When the connecting bearing 3 needs to be disassembled and repaired, first tighten the fixing bolt 7 to loosen the connection between the first fixing block 5 and the second fixing block 6, and then move the upper sleeve 202 upward to separate it from the lower sleeve 201.

[0033] Example 2: Please refer to Figure 3-Figure 5 In order to achieve the purpose of supporting and damping the rotating shaft, this embodiment provides the following technical solutions, which specifically disclose: a receiving groove 8 is opened inside the lower sleeve 201, and a supporting roller 9 for supporting the rotating shaft 4 is installed inside the receiving groove 8, and a shock-absorbing mechanism is arranged between the supporting roller 9 and the lower sleeve 201, and the shock-absorbing mechanism includes a connecting rod 10 rotatably installed in the middle position of the supporting roller 9, and the connecting rod 10 and the lower sleeve 201 are slidably connected, a shock-absorbing spring 11 is fixedly installed between the top end of the connecting rod 10 and the inner wall of the lower sleeve 201, and the interior of the connecting rod 10 is set to a hollow structure, a damping rod 12 is slidably installed on the top end of the connecting rod 10, and the top end of the damping rod 12 is fixedly connected to the lower sleeve 201, and the damping rod 12 is fixedly connected to the piston block 13 inside the connecting rod 10.

[0034] When the device is running, the supporting roller 9 inside the accommodating groove 8 is used to support the rotating shaft 4 to improve its rotation stability. When the rotating shaft 4 is slightly deformed, the rotation will squeeze the supporting roller 9. At this time, the supporting roller 9 pushes the connecting rod 10 to slide inside the lower sleeve 201. The connecting rod 10 is used to squeeze the shock-absorbing spring 11. At the same time, the damping rod 12 drives the piston block 13 to move inside the hollow connecting rod 10, squeezing the air to achieve the purpose of damping. The elastic effect of the shock-absorbing spring 11 is combined with the damping effect of the piston block 13 to achieve an effective shock-absorbing effect, thereby protecting the entire device and extending its service life.

[0035] Example 3: Please refer to Figure 6-Figure 7In order to facilitate the addition of lubricating oil, this embodiment provides the following technical solutions, which specifically disclose: an oil filling pipe 14 is fixedly installed on the upper surface of the upper sleeve 202, and four oiling nozzles 15 are fixedly installed on the lower surface of the upper sleeve 202. The positions of the oiling nozzles 15 correspond to the positions of the connecting bearings 3, and the oiling nozzles 15 are connected to the oil filling pipe 14 through the connecting pipe 16. A pressurized airbag 17 connected to the connecting pipe 16 is fixedly installed on the upper end of the connecting pipe 16, and the pressurized airbag 17 is located directly below the oil filling pipe 14, and an up and down sliding telescopic structure is formed between the oil filling pipe 14 and the upper sleeve 202.

[0036] After using it for a period of time, the staff adds lubricating oil to the oil filling pipe 14. The lubricating oil passes through the pressurized airbag 17 and then enters the oiling nozzle 15 from the connecting pipe 16, and is finally discharged from the oiling nozzle 15 to achieve the purpose of lubricating the connecting bearing 3. At this time, the staff can press the oil filling pipe 14 downward, use the oil filling pipe 14 to squeeze the pressurized airbag 17, and use the pressurized airbag 17 to blow air into the connecting pipe 16 to increase the internal air pressure of the connecting pipe 16, thereby speeding up the oiling speed of the oiling nozzle 15.
