[0038] In the actual installation process, the sealing bearing 2 can be installed at a certain distance on the rotating shaft 6 first, and then the sealing bearing 2 is placed on the base 101, and the upper seat 106 is fixed on the base 101 to complete the installation. This way is more convenient for assembly. In the case that the rotating shaft 6 is not convenient to disassemble, the sealing bearing 2 can be installed first, and then the rotating shaft 6 is inserted into the inner ring of the sealing bearing 2 to complete the installation. The inner ring of the sealing bearing 2 and the rotating shaft 6 are in interference fit.

[0039] During the rotation of the rotating shaft 6, the two sealing bearings 2 bear the radial and axial forces. However, in the actual processing and installation process, the following situations may occur: on the one hand, it is difficult to ensure that the axes of the two sealing bearings 2 are consistent, and there is a certain error. However, under a certain error, one of the sealing bearings 2 may be subjected to excessive force. On the other hand, due to the different distances of the two sealing bearings 2 from the driving point, when the sealing bearing 2 close to the driving point is slightly worn, the rotating shaft 6 may appear reasonable slight jumping or vibration. At this time, the sealing bearing 2 far from the driving point will be subjected to greater radial force. At this time, the damage to the sealing bearing 2 will be aggravated, and if it is not replaced in time, it will affect the use of the entire equipment and have certain safety hazards.

[0040] At present, the double-bearing bearing seat formed by integral casting may be accompanied by vibration during actual use, on the one hand, which may aggravate the damage to the other sealing bearing 2, on the other hand, it may cause deformation or cracks in the middle of the bearing seat, and the replacement cost is high at this time.

[0041] Therefore, the connecting part 3 for buffering the vibration of the support part 1 is arranged between the two support parts 1.

[0044] Part of the lubricating oil is stored at the collection groove 305 of the connecting part 3, and in the process of rotating the rotating shaft 6, the lubricating oil is circulated by the micro circulating pump 4, the cooling liquid is then sucked by the liquid suction pipe 401, and then discharged by the supply liquid pipe 402, part of the lubricating oil is sprayed into the sealing bearing 2, lubricating the rollers in the sealing bearing 2, and the lubricating oil also has a certain heat absorption function, absorbs heat, and the lubricating oil gradually increases after absorbing heat and flows into the collection groove 305 for circulation, at this time, the lubrication is carried out by the real-time oil supply mode, which can effectively prevent the temperature of the sealing bearing 2 from being too high under high load, affecting the strength and normal work of the sealing bearing 2.

[0045] In another embodiment, referring to Figure 7 and Figure 8 , the inner wall of the connecting part 3 is provided with a plurality of inner honeycomb grooves 301 arranged at equal intervals, a plurality of inner honeycomb grooves 301 are arranged in a ring shape and are provided with flow guide openings 302, and the flow guide openings 302 at the lower end penetrate into the collection groove 305.

[0046] Part of the lubricating oil sprayed by the spray groove one 404 enters the inner honeycomb groove 301, the heat of the lubricating oil entering the inner honeycomb groove 301 is fully absorbed by the inner wall of the inner honeycomb groove 301, and finally conducts heat to the outer wall of the connecting part 3 for heat dissipation, thereby effectively improving the heat dissipation effect of the lubricating oil, preventing the high temperature of the lubricating oil from affecting its lubricating effect, and at the same time, the lubricating oil as a medium can improve the heat dissipation effect of the sealing bearing 2 and the supporting part 1.

[0048] Referring to Figure 5 and Figure 12 , the outer side of the connecting part 3 is provided with an outer honeycomb groove 303.

[0049] The outer honeycomb groove 303 arranged correspondingly with the inner honeycomb groove 301 can conduct heat, thereby increasing the heat dissipation area in a limited space, and the overall vibration of the connecting part 3 can improve the heat exchange between the outer honeycomb groove 303 and the external air, thereby effectively improving the heat dissipation effect;

[0050] Through the arrangement of the inner honeycomb groove 301 and the outer honeycomb groove 303, the vibration buffering effect of the two-end supporting part 1 can be further improved, and the external load can be evenly distributed to each honeycomb unit. At the same time, the inner honeycomb groove 301 and the outer honeycomb groove 303 have a certain noise reduction effect, avoiding excessive vibration noise.

[0052] The vibration sensor 502 arranged at the connecting part 3 can detect the vibration condition of the connecting part 3 in real time, so as to further feed back the vibration condition of the rotating shaft 6. When the vibration range reaches the preset value one, the staff can repair and replace it according to the signal received by the external control end, avoiding certain safety hazards caused by excessive vibration.

[0053] Referring to Figure 3 and Figure 4 , the upper part of the connecting part 3 is detachably connected with an electric telescopic rod 5, the telescopic end of the electric telescopic rod 5 is sealingly and slidingly connected with a detection rod 501, and a spring 504 is fixedly connected between one end of the detection rod 501 and the telescopic end of the electric telescopic rod 5.

[0054] In the actual detection process, the vibration sensor 502 first detects the vibration condition of the connecting part 3. When the vibration data reaches the set value two, the external control end controls the electric telescopic rod 5 to extend a specified distance, so that the rolling ball 503 contacts the outer wall of the rotating shaft 6. At this time, with the vibration of the rotating shaft 6, the detection rod 501 can be vibrated, thereby accurately detecting the vibration condition of the rotating shaft 6, and avoiding the influence of directly installing the sensor on the rotating shaft 6 on the stability of the rotation.

[0055] In the specific embodiment, an outer sheath 7 is further interference-fitted on the rotating shaft 6, and the outer sheath 7 is interference-fitted with the inner rings of the two sealing bearings 2.

[0056] The outer sleeve 7 can be installed in cooperation with the sealing bearing 2, and the outer sleeve 7 can be used to fix the distance of the sealing bearing 2, and the outer sleeve 7 can prevent the lubricating oil from entering the connection between the rotating shaft 6 and the inner ring of the sealing bearing 2, thereby preventing the sliding phenomenon.

[0057] Referring to Figure 10 , the outer sleeve 7 is provided with a plurality of annular grooves 701, one of which corresponds to the rolling ball 503.

[0058] By setting a plurality of annular grooves 701, the lubricating oil flowing on the outer sleeve 7 can be collected, and then thrown out under the action of centrifugal force, so that the lubricating oil enters the inner honeycomb groove 301, avoiding the lubricating oil flowing on the outer sleeve 7 to the sealing bearing 2, thereby effectively preventing the lubricating oil from entering the connection between the rotating shaft 6 and the sealing bearing 2, especially in the case of up and down vibration of the rotating shaft 6, which may cause a gap between the outer edge of the outer sleeve 7 and the sealing bearing 2;

[0059] By contacting the rolling ball 503 with the annular groove 701 in the middle, the influence of the detection accuracy of the outer sleeve 7 by the debris adhered to the outer sleeve 7 can be avoided.
