[0022] As mentioned in the background technology of this application, the inventor has discovered through research that the existing bearing seat needs to press the bearing into the bearing seat little by little during the installation of the bearing, and a hammer or press is also used in the process. In order to facilitate the installation of the bearing, people have developed a split bearing seat, in which the bearing is first placed in the bearing seat and then connected and fixed. However, this split structure is composed of multiple independent components, which need to be assembled during the installation process. Due to the existence of manufacturing and assembly errors, there may be gaps or deviations in the fit between the components, which will affect the overall stability of the structure and have certain defects.

[0023] In order to solve the above-mentioned defects, the present application discloses a bearing with a seat that can be stably installed, which can find a balance point between the integral structure and the split structure, making the installation of the bearing more stable and convenient.

[0024] The following will describe in detail how the solution of the present application solves the above technical problems in conjunction with the accompanying drawings.

[0027] In this embodiment, a rotating shaft 5 is provided between a corner of the side of the bearing stand 4 and the inner wall of the middle groove 3, and the bearing stand 4 is rotatably connected to the middle groove 3 via the rotating shaft 5.

[0029] In this embodiment: the oil delivery mechanism specifically includes: a strip cavity 14 opened in the middle position inside the base 1, an elastic capsule 15 is arranged inside the strip cavity 14, and the elastic capsule 15 is filled with lubricating oil, one end of the strip cavity 14 is movably connected with a pressing block 16 matching the strip cavity 14, and a limiter is arranged above the pressing block 16, an oil delivery pipe 13 connected to the elastic capsule 15 is embedded above the elastic capsule 15, and an oil delivery port 28 is arranged at a position corresponding to the oil delivery pipe 13 on the inner wall of the first circular groove 9. The oil delivery mechanism set in this application can quickly deliver the lubricating oil in the elastic capsule 15 to the first circular groove 9 above by pressing when needed, so as to complete the lubrication of the bearing body 12, and at the same time, it can also recover excess lubricating oil, and in the process of the lubricating oil being recovered downward, it can take away the wear impurities generated in the first circular groove 9 to a certain extent.

[0030] In this embodiment, the limiting member specifically includes: a strip limiting groove 18 provided on the top wall of the strip cavity 14, the top of the pressing block 16 is fixedly connected to the limiting block 17, and the limiting block 17 is movably connected inside the strip limiting groove 18 and matches it. The setting of the limiting member improves the stability of the pressing block 16 during the movement process.

[0031] In this embodiment: the position-limiting ejection mechanism specifically includes: a notch 19 provided on the bottom end face of the middle groove 3, a telescopic block 20 matching the notch 19 is movably connected inside the notch 19, and an embedding groove 21 is provided on the bottom end face of the telescopic block 20, a spring column 22 is provided inside the embedding groove 21, and the two ends of the spring column 22 are respectively fixedly connected to the top of the embedding groove 21 and the bottom end of the notch 19. The position-limiting ejection mechanism provided in the present application can eject the bearing platform 4 outward at a certain angle after the bolt 8 is screwed out, so as to facilitate the staff to grasp the bearing platform 4 to complete the subsequent rotation. At the same time, the position-limiting ejection mechanism can also play a role in position-limiting calibration when the bearing platform 4 is rotated back to the middle groove 3.

[0032] In this embodiment: the adjusting member specifically includes: a slot 23 provided on one side of the first circular groove 9, a rectangular slot 25 is provided between the slot 23 and the first circular groove 9, and a block 24 is movably connected inside the slot 23, a connecting block 26 matching the rectangular slot 25 is fixedly connected to the outer side of the block 24, and an arc plate 27 is fixedly connected to one end of the connecting block 26, and the inner side of the arc plate 27 contacts and matches the bearing body 12. The present application can select a suitable adjusting member for tightening according to the size of the bearing body 12, so that the adaptability of the seat bearing is higher.

[0033] In this embodiment: a second circular groove 10 is provided at the center of the side surface of the first circular groove 9, a third circular groove 11 is provided at a position on the inner wall of the middle groove 3 corresponding to the second circular groove 10, and the centers of the second circular groove 10 and the third circular groove 11 are located on the same central axis. The second circular groove 10 and the third circular groove 11 are provided for connecting a subsequent shaft body, and the diameter of the second circular groove 10 is greater than the diameter of the third circular groove 11.

[0034] The working principle of the present invention is: when in use, first, unscrew the three bolts 8 one by one, and then, the spring column 22 of the limit ejection mechanism releases the elastic potential energy to push the telescopic block 20 in the slot 19 upward. During the process, the bearing platform 4 is ejected outward at a certain angle. Then, the staff grabs the bearing platform 4 and continues to rotate it outward until the first circular groove 9 of the bearing platform 4 completely exposes the middle groove 3. Then, the staff puts the bearing body 12 into the first circular groove 9, and then turns the bearing platform 4 back to the middle groove 3 until the bearing platform 4 presses the telescopic block 20 down and rests on the bottom end surface of the slot 19. At this time, the top of the oil delivery pipe 13 is docked with the oil delivery port 28, and the second threaded hole 7 is aligned with the first threaded hole 6 one by one, and then the bolt 8 is screwed on. The entire installation process is simple and efficient, and it is neither as difficult to install as an integral structure, nor as unstable as a split structure. It should be noted that if the diameter of the bearing body 12 is smaller than the diameter of the first circular groove 9 and the sizes of the two do not match, it is only necessary to select a suitable adjustment member, the length of the connecting block 26 of the selected adjustment member is just enough to allow the arc plate 27 to abut against the outside of the bearing body 12, and the inner wall of the arc plate 27 matches the outer circle of the bearing body 12. After the block 24 of the selected adjustment member is inserted into the slot 23 and the connecting block 26 is correspondingly inserted into the rectangular slot 25, the bearing body 12 is inserted between the four arc plates 27 to complete the installation, and finally the bearing stand 4 is turned back to the middle slot 3 for fixing.

[0035] During the use of the seated bearing, it is necessary to regularly inject an appropriate amount of lubricating oil into the bearing body 12. The present application adopts an oil delivery mechanism that can quickly deliver the lubricating oil in the elastic capsule 15 to the upper first circular groove 9 by pressing when needed, so as to complete the lubrication of the bearing body 12. Specifically, the pressing block 16 is pressed inwardly so that the pressing block 16 moves inwardly along the strip cavity 14. During the process, the limit block 17 and the strip limit groove 18 are relatively displaced, and the elastic capsule 15 is deformed by the squeezing of the pressing block 16. The internal pressure of the elastic capsule 15 increases, so that the lubricating oil inside it enters the first circular groove 9 from the oil delivery port 28 along the oil delivery pipe 13 to lubricate the bearing body 12. At the same time, after releasing the pressing block 16, the elastic capsule 15 returns to its initial state and can also absorb and recover excess lubricating oil. In the process of the lubricating oil being recovered downward, it can take away the wear impurities generated in the first circular groove 9 to a certain extent, thereby improving the stability of the operation of the bearing body 12.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0037] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
