Description

Technical Field

[0001] The present invention relates to the technical field of slewing bearings, in particular to a coordinated rotating slewing bearing. Background Art

[0002] Slewing bearing is a large bearing that can bear comprehensive loads. It can bear large axial, radial loads and overturning moments at the same time. Slewing bearing is widely used in real industry and is called "machine joint". It is an important transmission component required for machinery that needs to make relative rotation between two objects and bear axial force, radial force and overturning moment at the same time. With the rapid development of the machinery industry, slewing bearings have been widely used in ship equipment, engineering machinery, light industrial machinery, metallurgical machinery, medical machinery, industrial machinery and other industries.

[0003] As a heavy-duty bearing, the internal structure of the slewing bearing is generally a steel ball plus a spacer block or a roller plus a spacer block. Compared with ordinary bearings, it has the characteristics of large load-bearing capacity but slow rotation speed. The rotation speed has been an unresolved problem. Because the heat dissipation cannot be solved during high-speed rotation, it is easy to cause the slewing bearing track to overheat and reduce the service life. In addition, the seal of the slewing bearing is an external sealing belt seal, which is prone to the problem of the sealing belt falling off due to extrusion during rotation. The slewing bearing is relatively cumbersome to assemble, and technicians need to use professional assembly tools to assemble it, which makes the assembly complicated and brings difficulties to subsequent maintenance. Therefore, a cooperative rotating slewing bearing is proposed to solve the above technical defects. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a cooperative rotating slewing bearing, in which stirring teeth are arranged between the inner ring and the outer ring, and the outer edge teeth are coordinated to ensure uniform heating. With the arrangement of the bottom gasket and the top gasket, the connection strength between the inner ring and the outer ring is enhanced, and at the same time, effective sealing between the inner ring and the outer ring is ensured, thereby solving the problems of not being able to quickly dissipate heat, reducing the service life, and complex assembly and difficulty in maintenance.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a cooperatively rotating slewing bearing, comprising an inner ring, an outer ring and a rotating assembly arranged between the inner ring and the outer ring, the inner arc surface of the outer ring is fixedly installed with a first anti-slip plate and a second anti-slip plate in sequence from top to bottom, and a plurality of first balls are slidably installed between the first anti-slip plate and the second anti-slip plate on opposite sides, a bottom gasket is arranged at the bottom of the opposite side of the inner ring and the outer ring, and the bottom gasket and the second anti-slip plate are fixedly connected by a first inner hexagon bolt, the rotating assembly comprises a heat conductive limit ring, and the heat conductive limit ring A plurality of second balls are evenly inlaid on the outer circumference, and the outer surfaces of the second balls are in contact with the opposite side of the inner ring and the outer ring. A plurality of positioning cylinders are fixedly installed on the top of the first anti-slip plate, and a plurality of through holes compatible with the positioning cylinders are opened on the top of the heat-conducting limit ring. Stirring teeth are sleeved and rotatably installed on the outer circumference of the positioning cylinder and located on the bottom of the heat-conducting limit ring, and the outer arc surface of the inner ring is provided with outer edge teeth compatible with the stirring teeth. A top gasket is provided on the top of the opposite side of the inner ring and the outer ring, and the top gasket and the positioning cylinder are fixedly connected by a second hexagon socket bolt.

[0008] By adopting the above technical scheme, stirring teeth are arranged between the inner ring and the outer ring, and the outer edge teeth are arranged in coordination, so that the inner ring can drive the stirring teeth to rotate in coordination during high-speed rotation, and the lubricating oil filled between the inner ring and the outer ring is fully distributed to ensure uniform heating. Under the setting of the heat-conducting limit ring, the effective heat dissipation of the slewing bearing is guaranteed, and under the setting of the bottom gasket and the top gasket, while ensuring the effective connection between the outer ring and the inner ring, the connection strength between the inner ring and the outer ring is further strengthened, and at the same time, the effective sealing between the inner ring and the outer ring is guaranteed, thereby effectively extending the service life of the slewing bearing.

[0009] The present invention is further configured as follows: the inner ring includes a main ring body and two shaping rings, the two shaping rings are coaxially arranged with the main ring body, and the outer edge dimensions of the two shaping rings are smaller than the outer edge dimensions of the main ring body, wherein the two shaping rings are respectively fixedly mounted on the top and bottom of the main ring body.

[0010] By adopting the above technical solution, two shaping rings and the main ring body are used to form the upper step and the lower step, so as to provide space for the assembly of the top gasket and the bottom gasket, thereby ensuring the smoothness of the surface of the slewing bearing after assembly, improving the aesthetic appearance of the slewing bearing, and ensuring that the top gasket and the bottom gasket effectively block the space between the inner ring and the outer ring, thereby avoiding leakage of lubricating oil.

[0011] The present invention is further configured as follows: a through hole matching the positioning tube is provided on the top of the stirring tooth.

[0012] The present invention is further configured as follows: the top and bottom of the stirring teeth are both provided with isolation sleeves matched with the positioning tube, and the bottom of the heat-conducting limiting ring is provided with an expansion port matched with the isolation sleeve.

[0013] By adopting the above technical scheme, the setting of the through hole and the positioning tube provide convenience for the installation of the stirring teeth. The setting of the isolation sleeve can preliminarily isolate the contact between the stirring teeth and the first anti-slip plate and the thermal limit ring, thereby reducing the damage caused to the first anti-slip plate and the thermal limit ring by the stirring teeth when rotating at high speed. Under the setting of the expanded hole, the position of the isolation sleeve is limited to ensure the stability of the thermal limit ring after assembly.

[0014] The present invention is further configured as follows: a plurality of first oil leakage holes are provided on the outer periphery of the positioning cylinder, and a plurality of second oil leakage holes connected with the through holes are provided on the outer surface of the heat-conducting limiting ring.

[0015] By adopting the above technical solution, the first oil leakage hole and the second oil leakage hole are set, when there is lubricating oil in the through hole, it can flow to between the inner ring and the outer ring through the first oil leakage hole and the second oil leakage hole, so that after the second hexagon socket bolt is removed, the lubricating oil can be added between the inner ring and the outer ring through the top gasket, thereby ensuring the effective addition of the lubricating oil.

[0016] The present invention is further configured as follows: a sliding groove adapted to the first ball is provided between opposite sides of the first anti-slip plate and the second anti-slip plate.

[0017] The present invention is further configured as follows: a threaded hole matched with the first hexagon socket bolt is provided at the bottom of the second anti-drop plate, and the threaded hole is communicated with the interior of the slide groove.

[0018] By adopting the above technical solution, the position of the first ball is limited under the setting of the slide groove, and the threaded hole is set to ensure the effective connection between the bottom gasket and the second anti-drop plate. After the first hexagon socket bolt is removed, the lubricating oil between the inner ring and the outer ring can leak out from the threaded hole, thereby providing convenient conditions for the subsequent maintenance of the slewing bearing.

[0019] The present invention is further configured as follows: the outer arc surface of the top gasket, the outer arc surface and the inner arc surface of the bottom gasket are sequentially provided with a first sealing groove, a clamping groove and a second sealing groove from top to bottom; the interiors of the first sealing groove and the second sealing groove are filled with sealing gaskets; a plurality of third balls are placed inside the clamping grooves; the third ball surface and the sealing gasket arranged on the outer arc surface of the bottom gasket are both in contact with the inner arc surface of the outer ring; the third ball surface and the sealing gasket arranged on the inner arc surface of the bottom gasket are both in contact with the outer arc surface of the inner ring.

[0020] By adopting the above technical solution and utilizing the arrangement of the sealing gaskets in the first sealing groove and the second sealing groove, the sealing effect between the top gasket and the bottom gasket and the outer ring is fully guaranteed, and under the arrangement of the third ball, a large friction force between the outer ring and the top gasket and the bottom gasket is avoided, thereby reducing the heat generation of the slewing bearing and further extending the service life of the slewing bearing.

[0021] (III) Beneficial effects

[0022] The present invention provides a coordinated rotating slewing bearing having the following beneficial effects:

[0023] (1) The cooperatively rotating slewing bearing has stirring teeth arranged between the inner ring and the outer ring, and cooperates with the arrangement of the outer edge teeth, so that the inner ring drives the stirring teeth to rotate cooperatively during high-speed rotation, and the lubricating oil filled between the inner ring and the outer ring is fully distributed to ensure uniform heating. Under the arrangement of the heat-conducting limit ring, the effective heat dissipation of the slewing bearing is ensured, and under the arrangement of the bottom gasket and the top gasket, the effective connection between the outer ring and the inner ring is ensured, and the connection strength between the inner ring and the outer ring is further strengthened, and the effective sealing between the inner ring and the outer ring is ensured, thereby effectively extending the service life of the slewing bearing.

[0024] (2) The cooperative rotating slewing bearing uses two shaping rings and a main ring body to form an upper step and a lower step, thereby providing space for the assembly of a top gasket and a bottom gasket, ensuring a smooth surface after the slewing bearing is assembled, improving the aesthetic appearance of the slewing bearing, and ensuring that the top gasket and the bottom gasket effectively seal the space between the inner ring and the outer ring, thereby avoiding leakage of lubricating oil.

[0025] (3) The cooperatively rotating slewing bearing, through the setting of the through hole and the cooperation of the positioning cylinder, provides convenience for the installation of the stirring teeth. The setting of the isolation sleeve provides preliminary isolation for the contact between the stirring teeth and the first anti-slip plate and the thermal limit ring, thereby reducing the damage caused to the first anti-slip plate and the thermal limit ring by the stirring teeth when rotating at high speed. Under the setting of the expansion hole, the position of the isolation sleeve is limited to ensure the stability of the thermal limit ring after assembly.

[0026] (4) The cooperatively rotating slewing bearing has the first oil leakage hole and the second oil leakage hole. When lubricating oil is in the through hole, the lubricating oil can flow through the first oil leakage hole and the second oil leakage hole to between the inner ring and the outer ring. After the second hexagon socket bolt is removed, the lubricating oil can be added between the inner ring and the outer ring through the top gasket, thereby ensuring the effective addition of the lubricating oil.

[0027] (5) The cooperatively rotating slewing bearing limits the position of the first ball by setting the slide groove, and ensures the effective connection between the bottom gasket and the second anti-drop plate by setting the threaded hole. After the first hexagon socket bolt is removed, the lubricating oil between the inner ring and the outer ring can leak out from the threaded hole, thereby providing convenient conditions for the subsequent maintenance of the slewing bearing.

[0028] (6) The cooperatively rotating slewing bearing fully ensures the sealing effect between the top gasket and the bottom gasket and the outer ring by utilizing the arrangement of the sealing gaskets in the first sealing groove and the second sealing groove. In addition, under the arrangement of the third ball, it avoids the outer ring and the top gasket and the bottom gasket from generating a large friction force, thereby reducing the heat generation of the slewing bearing and further extending the service life of the slewing bearing.

As a detailed description, as shown in the attached Figure 4 As shown, a through hole 19 adapted to the positioning tube 11 is formed at the top of the stirring tooth 13 .

[0047] Furthermore, in order to reduce the damage caused by the stirring teeth 13 to the first anti-slip plate 4 and the heat-conducting limit ring 9 when rotating at high speed, the top and bottom of the stirring teeth 13 are provided with isolation sleeves 20 that are compatible with the positioning cylinder 11, and the bottom of the heat-conducting limit ring 9 is provided with an expansion port 21 that is compatible with the isolation sleeve 20.

[0048] As a preferred solution, the outer arc surface of the inner ring 1 is provided with outer edge teeth 14 adapted to the stirring teeth 13, and a top gasket 15 is provided on the top of the opposite side of the inner ring 1 and the outer ring 2, and the top gasket 15 and the positioning cylinder 11 are fixedly connected by a second hexagon socket bolt 16.

[0053] When adding lubricating oil: unscrew a second hexagon socket bolt 16, inject lubricating oil into the positioning cylinder 11, and the lubricating oil flows into the through hole 12 through the first oil leakage hole 22, and then flows between the inner ring 1 and the outer ring 2 through the second oil leakage hole 23;

[0054] When the lubricating oil is discharged: unscrew a first hexagon socket bolt 8, and the lubricating oil can leak out through the slide groove 24 and the threaded hole 25.
