Description

Technical Field

[0001] The utility model belongs to the technical field of thrust sliding bearings, in particular to a thrust sliding bearing. Background Art

[0002] Definition of thrust sliding bearing: a sliding bearing that bears axial loads (along or parallel to the axis of rotation). A thrust sliding bearing is a sliding bearing used to limit axial movement. In mechanical equipment, in order to ensure the correct position of major parts such as shafts and bearings and avoid equipment damage due to excessive movement, thrust bearings are usually used to achieve this function. Thrust bearings are usually composed of one or more thrust rings. These thrust rings are installed at one end or in the middle of the bearing and cooperate with the inner hole of the bearing to prevent or limit axial sliding.

[0003] Most existing thrust sliding bearings are generally installed at the desired position by bolts before use. Since a large number of bolts need to be installed, the installation or disassembly of the thrust sliding bearing is relatively cumbersome, which reduces the efficiency of the installation or disassembly of the thrust sliding bearing. Therefore, a thrust sliding bearing is proposed. Utility Model Content

[0007] Furthermore, the bottoms of both sides of the lower mounting seat are fixedly connected with mounting plates, and both sides of the upper surfaces of the two mounting plates are threadedly connected with mounting bolts, the plug-in block is fixedly clamped to the inside of the plug-in slot through the clamping block, and the upper mounting seat is fixedly connected to the limit slot and the lower mounting seat through the clamping block.

[0008] Furthermore, the disassembly mechanism includes two elastic rods respectively fixedly connected to one side of the lower mounting seat and close to both sides of the limit slot, one end of the two elastic rods is commonly fixedly connected to a pressing plate, one side of the pressing plate is symmetrically fixedly connected to a push rod, and the two push rods correspond to the clamping blocks.

[0009] Furthermore, the thrust mechanism includes four fixing grooves respectively opened on the opposite sides of the upper mounting seat and the lower mounting seat, and the interiors of the four fixing grooves are slidably plugged with fixing blocks, and the opposite sides of the four fixing blocks are commonly fixedly connected with bearings, and both sides of the bearing surface are fixedly connected with sealing gaskets.

[0010] Furthermore, support plates are fixedly connected to both sides of the upper mounting seat and the lower mounting seat surface, and the four support plates are respectively fitted with corresponding sealing gaskets. The upper surface and the lower surface of the bearing are both provided with eight corresponding connecting grooves in a path array, and a connecting rod is fixedly connected to the inside of each connecting groove.

The disassembly of the mounting seat not only facilitates the disassembly of the thrust mechanism, but also reduces the use of springs and bolts. Furthermore, the provision of the sealing gasket and the oil filling port not only prevents external debris from entering the interior of the thrust sliding bearing, but also allows lubricating oil to be injected into the interior of the thrust sliding bearing, thereby avoiding the thrust sliding bearing having a large internal friction force that reduces its service life.

[0027] The upper mounting seat 5 is fixedly connected to the limit slot 9 and the lower mounting seat 1 through the clamping block 8. The two clamping blocks 8 are respectively inserted into the corresponding limit slots 9. A disassembly mechanism is installed on both sides of the lower mounting seat 1 near the limit slots 9. The disassembly mechanism includes two elastic rods 11 respectively fixedly connected to one side of the lower mounting seat 1 and close to both sides of the limit slot 9. One end of the two elastic rods 11 is fixedly connected to a pressing plate 12. One side of the pressing plate 12 is fixedly connected to a pushing rod 13 in a symmetrical manner. The two pushing rods 13 correspond to the clamping block 8. When the thrust sliding bearing needs to be disassembled, the pressing plate 12 is pushed so that the pressing plate 12 drives the pushing rod 13 to move, so that the pushing rod 13 pushes the clamping block 8 to be inserted into the inside of the limit slot 9, so that the clamping block 8 is disengaged from the limit slot 9, so that the plug-in block 4 is no longer clamped in The interior of the plug-in groove 2 allows the upper mounting seat 5 to be disengaged from the lower mounting seat 1, thereby making it easier to disassemble the thrust sliding bearing. A thrust mechanism is commonly installed on the opposite sides of the lower mounting seat 1 and the upper mounting seat 5. The thrust mechanism includes four fixing grooves 14 respectively opened on the opposite sides of the upper mounting seat 5 and the lower mounting seat 1. The interiors of the four fixing grooves 14 are all slidably plugged with fixing blocks 15. The opposite sides of the four fixing blocks 15 are commonly fixedly connected with bearing shells 16. Through the provision of the fixing blocks 15, when the bearing shells 16 are installed, the fixing blocks 15 are plugged into the interiors of the fixing grooves 14, thereby making the installation of the bearing shells 16 more stable. Sealing gaskets 17 are fixedly connected to both sides of the surface of the bearing shells 16. Through the provision of the sealing gaskets 17, both sides of the upper mounting seat 5 and the lower mounting seat 1 are sealed, thereby preventing external debris from entering the interiors of the two.

[0028] The upper mounting seat 5 and the lower mounting seat 1 are fixedly connected to the two sides of the surface with a bearing plate 18. The bearing shell 16 is placed on the lower mounting seat 1. The setting of the bearing plate 18 makes the position of the bearing shell 16 more accurate, thereby making the installation of the bearing shell 16 more convenient. The four bearing plates 18 are respectively fitted with the corresponding sealing gaskets 17. The upper and lower surfaces of the bearing shell 16 are arranged in a path array with eight corresponding connecting grooves 19. The interior of each connecting groove 19 is fixedly connected to a connecting rod 20. Every four The surfaces of the corresponding connecting rods 20 are commonly fixedly connected with thrust rings 21. The two thrust rings 21 are respectively inserted into the two ends of the bearing shell 16. The thrust rings 21 are fixedly connected to the bearing shell 16 through the connecting rod 20. One side of the two thrust rings 21 is fixedly connected with a lubrication plate 22. The thrust ring 21 fits with the thrust block on the surface of the rotating shaft. Through the setting of the lubrication plate 22, the thrust ring 21 and the thrust block are lubricated, thereby avoiding excessive friction of the thrust ring 21 and resulting in a reduction in the service life of the thrust ring 21.

[0029] Specifically, when the thrust sliding bearing is in use: when installing the thrust sliding bearing, the bearing shell 16 is placed on the lower mounting seat 1. By setting the bearing plate 18, the position of the bearing shell 16 is more accurate, thereby making the installation of the bearing shell 16 more convenient. Then, the plug-in block 4 is inserted into the inside of the plug-in slot 2, so that the clamping block 8 compresses the elastic plate 7 and is inserted into the inside of the mounting slot 6. When the clamping block 8 moves to be parallel to the limit slot 9, the elastic force of the elastic plate 7 causes the clamping block 8 to pop out, thereby The clamping block 8 is inserted into the limiting groove 9 to complete the clamping of the clamping block 8, so that the upper mounting seat 5 is fixedly clamped to the upper surface of the lower mounting seat 1. At the same time, the upper mounting seat 5 is fitted with the bearing shell 16, and the bearing shell 16 is limited, thereby completing the installation of the bearing shell 16, so that the thrust ring 21 and the lubricating plate 22 are both installed. Moreover, through the setting of the fixing block 15, when the bearing shell 16 is installed, the fixing block 15 is inserted into the fixing groove 14, so that the installation of the bearing shell 16 is more stable.

[0030] The thrust ring 21 is fitted with the thrust block on the surface of the rotating shaft. The lubricating plate 22 is provided to lubricate the thrust ring 21 and the thrust block, thereby preventing the thrust ring 21 from having excessive friction and thus reducing the service life of the thrust ring 21. At the same time, the sealing gasket 17 is provided to seal both sides of the upper mounting seat 5 and the lower mounting seat 1, thereby preventing external debris from entering the interior of the two. The oil filling port is provided to inject lubricating oil into the interior of the thrust sliding bearing, thereby improving the service life of the thrust sliding bearing. The sealing plug 23 is provided to limit the oil filling port when not in use.

[0031] When the thrust sliding bearing needs to be disassembled, the pressing plate 12 is pushed, so that the pressing plate 12 drives the pushing rod 13 to move, so that the pushing rod 13 pushes the clamping block 8 to be inserted into the inside of the limiting groove 9, so that the clamping block 8 is disengaged from the limiting groove 9, so that the plug-in block 4 is no longer clamped in the inside of the plug-in groove 2, so that the upper mounting seat 5 is disengaged from the lower mounting seat 1, thereby making the thrust sliding bearing disassembly more convenient, and through the setting of the elastic block 3, when the clamping block 8 is disengaged from the limiting groove 9, the elastic force of the elastic block 3 is used to make the upper mounting seat 5 automatically pop out of the plug-in groove 2, so that the upper mounting seat 5 is disassembled more quickly, thereby improving the efficiency of installation and disassembly of the thrust sliding bearing.
