Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vertical sliding bearing guide pads, and specifically relates to a guide pad structure for a vertical sliding bearing. Background Technique
[0002] For a vertical sliding bearing, due to its structural characteristics, it needs to operate with self-lubrication, that is, during use, the bearing oil chamber is filled with the amount of oil required for bearing lubrication. The power consumption heat generated during the operation of the vertical sliding bearing is taken away through heat exchange by a cooler, so that the vertical sliding bearing operates normally. The power consumption heat generated during the operation of the guide pad is taken away by oil. In order to keep the temperature of the guide pad at a relatively low temperature and operate safely and reliably for a long time, this requires that the guide pad itself has as large a heat dissipation area as possible to be in full contact with the oil.
[0003] For the existing guide pad structure for a vertical sliding bearing, during use, usually extremely high requirements are placed on the dimensional accuracy of the internally fixed rotating shaft. Generally, a rotating shaft of a certain size requires the use of a guide pad of a corresponding size, and the adaptability is poor. Moreover, for the existing guide pad structure for a vertical sliding bearing, during operation, lubricating oil needs to be introduced to play the roles of lubrication and heat dissipation. The heat dissipation effect of the traditional structure is poor, and the rotating shaft in a high temperature environment for a long time is prone to deformation, affecting the accuracy. Therefore, the existing guide pad structure for a vertical sliding bearing has the disadvantages of poor heat dissipation effect and poor adaptability. Summary of the Utility Model

[0028] In order to facilitate improving the heat dissipation effect, as shown in the attached Figures 1 to 5As shown in the figure, the present application adopts the following structure. Through the settings of the liquid inlet pipe 3, the liquid outlet pipe 4, the lubricating oil flow channel 6, the lubricating groove 8, the through hole 9, the annular communication channel 10 and the heat sink 22, the guide shoe 7 structure for the vertical sliding bearing has the effect of improving the heat dissipation effect of the bearing body 20. Through the coordinated settings of the liquid inlet pipe 3, the liquid outlet pipe 4, the lubricating oil flow channel 6, the lubricating groove 8, the through hole 9 and the annular communication channel 10, during use, the lubricating oil can be pumped into the liquid inlet pipe 3 to fill the inside of the lubricating oil flow channel 6 and the lubricating groove 8. When the guide shoe 7 rotates, the lubricating oil on one side of the bearing body 20 is driven to enter the lubricating groove 8 from the through hole 9 and then discharged from the through hole 9 on the other side, so that the lubricating oil circulates inside the lubricating oil flow channel 6, the lubricating groove 8, the through hole 9 and the annular communication channel 10, and finally is discharged from the liquid outlet pipe 4. During the circulation process, through the setting of the annular communication channel 10, a plurality of hexagonal clamping blocks 19 can be connected outside the guide shoe 7 to prevent excessive pressure, so that the lubricating oil can well wrap the bearing body 20. The heat generated during operation can be taken away by the lubricating oil, and it can be in good contact with the inner wall of the device. Moreover, the lubricating oil inside the lubricating groove 8 can be in direct contact with the inner side wall of the bearing body 20, so that the heat generated by the rotation of the bearing body 20 can be taken away better. Through the setting of the heat sink 22, the second fixing block 21 can be well cooled, thus achieving the purpose of facilitating the improvement of the heat dissipation effect;
[0029] Embodiment 2
[0030] The technical solution provided by the present utility model is as follows: A rotating disk 11 is rotatably connected to the inner side wall of the guide shoe 7. A spiral chute 12 is provided on the outer surface of the rotating disk 11. A slider 13 is slidably connected to the inner side wall of the spiral chute 12. A clamping block 14 is fixedly connected to the outer surface of the slider 13. There are three clamping blocks 14 and they are evenly distributed in an annular array manner. An anti-slip groove 15 is provided on the inner side wall of the clamping block 14. An inclined meshing tooth 16 is provided on the outer surface of the rotating disk 11. A rotating shaft 17 is rotatably connected to the inner side wall of the guide shoe 7. A worm 18 is fixedly connected to the outer surface of the rotating shaft 17. The outer surface of the worm 18 is in transmission connection with the inner side wall of the inclined meshing tooth 16. One end of the rotating shaft 17 is fixedly connected to a hexagonal clamping block 19. A bearing body 20 is provided on the outer surface of the guide shoe 7 outside the lubricating groove 8. The upper surface of the first fixing block 1 is fixedly connected to a second fixing block 21 by bolts. The internal structure of the second fixing block 21 is the same as that of the first fixing block 1.
[0031] In order to achieve the facilitation of improving the adaptability, as shown in the appendix Figures 1 to 6As shown in the figure, the present application adopts the following structure. Through the settings of the rotating disk 11, spiral chute 12, clamping block 14, inclined meshing teeth 16, rotating shaft 17, worm 18 and hexagonal clamping block 19, the structure of the guide pad 7 for the vertical sliding bearing has the effect of improving the adaptability performance. During actual use, first, the middle part of the guide pad 7 needs to be sleeved on the rotating shaft to be limited. Then, the first fixing block 1 is fixed at the specified position with bolts. Then, the bearing body 20 is sleeved on the outer surface of the guide pad 7. Next, the guide pad 7 and the bearing body 20 are placed inside the first fixing block 1. Finally, the second fixing block 21 is fixed on the upper surface of the first fixing block 1 with bolts. Through the cooperative settings of the rotating disk 11, spiral chute 12, slider 13, clamping block 14, inclined meshing teeth 16, rotating shaft 17 and worm 18, during use, for rotating shafts with different diameters, a hexagonal wrench can be used to clamp the hexagonal clamping block 19 and then rotate the rotating shaft 17. The rotation of the rotating shaft 17 drives the rotation of the worm 18. Thus, through the transmission between the worm 18 and the inclined meshing teeth 16, the rotating disk 11 is driven to rotate inside the guide pad 7. When the rotating disk 11 rotates, due to the limitation of the spiral chute 12 and the slider 13, at this time, the three clamping blocks 14 can be driven to move synchronously towards or away from the middle. Furthermore, rotating shafts with different diameters can be fixed. The inclined meshing teeth 16 and the worm 18 can be well self-locked. After tightening the hexagonal clamping block 19, the fixing of the rotating shaft can be completed. The setting of the anti-slip groove 15 can well prevent the relative movement between the rotating shaft and the clamping block 14, improving the fixing effect. And the synchronous movement of the three clamping blocks 14 can ensure that the rotating shaft is in the central position during fixing, achieving the purpose of facilitating the improvement of adaptability.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
