Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1: As Figures 1-4 The system includes a self-lubricating support roller assembly, which includes a roller sleeve 100. The inner wall of the roller sleeve 100 is rotatably connected to a ring cooler track support roller 300. The inner wall of the roller sleeve 100 has a cavity 120. The top outer wall of the roller sleeve 100 is fixedly connected to a feeding pipe 140. The top outer wall of the feeding pipe 140 is threadedly connected to a sealing cap 141. A self-lubricating cylinder 130 is installed on the inner wall of the roller sleeve 100. The outer wall of the self-lubricating cylinder 130 is rotatably connected to the outer wall of the roller sleeve 100. The inner wall of the self-lubricating cylinder 130 has uniformly opened discharge holes 131. The outer wall of the roller sleeve 100 is threadedly connected to an end cap 170.

[0027] The specific application scenario of this embodiment is as follows: By installing a cavity 120 on the inner wall of the roller sleeve 100, and filling the cavity 120 with graphite powder, the graphite powder lubricates the outer wall of the ring cooler track support roller 300. By opening a discharge hole 131 on the inner wall of the self-lubricating cylinder 130, the graphite powder in the cavity 120 is slowly released onto the outer wall of the ring cooler track support roller 300, thereby facilitating continuous automatic lubrication. Since the ring cooler track support roller 300 dynamically blocks the discharge hole 131, the release rate of graphite powder is reduced, thereby facilitating the extension of the graphite powder addition cycle, reducing equipment maintenance costs, and improving the economy and stability of equipment operation.

[0028] Example 2: As Figures 4-7 A viewing window 110 is fixedly installed on the inner wall of the roller sleeve 100. The viewing window 110 is located on the outside of the cavity 120. The discharge hole 131 has a diameter of 0.1 mm. The inner wall of the outer side of the cavity 120 is open. An annular groove 150 is provided at the end of the open inner wall. There are two annular grooves 150, one inside and one outside. The inner walls of the two annular grooves 150 are fitted together to connect to a sealing ring 160. The outer wall of the inner side of the sealing ring 160 is fixedly installed with a first locking ridge 162 and a second locking ridge 162. Rib 163, first rib 162 and second rib 163 are inserted and connected to the inner walls of two annular grooves 150. The inner wall of the sealing ring 160 is provided with a sealing block 161. The outer wall of the sealing block 161 is inserted and connected to the opening inside the cavity 120 for sealing. The inner wall of the end cap 170 is fixedly connected with a threaded locking ring 171. The inner wall of the threaded locking ring 171 is provided with an internal thread 173 and the outer wall of the threaded locking ring 171 is provided with an external thread 172.

[0029] The specific application scenario of this embodiment is as follows: by setting the sealing ring 160 to fit tightly into the inner wall of the cavity 120, the structural stability when installing the end cover 170 is improved. The threaded locking ring 171 is set to improve the tightness when threadedly connected to the inner wall of the cavity 120. The double threaded connection of the external thread 172 and the internal thread 173 is set to improve the stability of the installation structure and extend the service life of the equipment.

[0030] Example 3: As Figure 3 and Figure 4 The outer wall of the threaded locking ring 171 is connected to the open inner wall by the internal thread 173 and the external thread 172 for threaded sealing. The outer wall of the end cover 170 is fixedly installed with a hexagonal prism 174. The hexagonal prism 174 is used with a wrench to control the rotation of the end cover 170. The outer wall of the roller sleeve 100 is fitted with a support ring 200. The top of the support ring 200 is fixedly connected to a snap ring 220 by bolts 230 and nuts 240. The bottom of the support ring 200 is welded to a support leg 210.

[0031] The specific application scenario of this embodiment is as follows: A sealing ring 160 is installed at the end of the cavity 120, so that the sealing ring 160 is snapped into the inside of the cavity 120. The end cap 170 is threadedly connected to the inner wall of the cavity 120, so as to facilitate sealing the port of the cavity 120 through the end cap 170, thereby preventing graphite powder from overflowing. By setting the support ring 200 and the snap ring 220 to work together, the installation of the support roller self-lubricating assembly is supported.

[0032] The working principle of this utility model is as follows: When used by those skilled in the art, the ring cooler track support roller 300 is installed on the inner wall of the self-lubricating cylinder 130, the sealing cover 141 is opened, and graphite powder is added into the cavity 120 inside the roller sleeve 100 through the feeding pipe 140. Then, the sealing cover 141 is installed on the top of the feeding pipe 140, and the graphite content in the cavity 120 is viewed through the viewing window 110. When the ring cooler track support roller 300 rotates, the graphite powder in the cavity 120 permeates to the outer wall of the ring cooler track support roller 300 through the discharge hole 131, which achieves an automatic lubrication effect on the outer wall of the ring cooler track support roller 300 and the inner wall of the self-lubricating cylinder 130.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
