DETAILED DESCRIPTION

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0019] like Figures 1-3 As shown, a submerged roller bearing housing with a bidirectional mounting surface includes a bearing housing body 1, a bushing 2 fixed inside the bearing housing body 1, an arm sleeve 3 fixed inside the bushing 2, and the bearing housing body 1 is installed in the mounting groove 51 of the submerged roller support arm 5. Since the mounting groove 51 of the submerged roller support arm 5 is a dovetail groove, in order to adapt to the mounting groove 51, mounting bosses 11 are symmetrically provided on the upper and lower sides of the bearing housing body 1. The mounting bosses 11 are dovetail shaped and can be installed in the mounting groove 51.

[0020] The mounting bosses 11 on the upper and lower sides of the bearing housing body can both serve as contact surfaces with the submerged roller support arm 5. After the submerged roller bearing housing has been installed, the arm sleeve 3 will wear out after a period of operation. At this time, the two contact surfaces of the bearing housing body can be interchanged without replacing the arm sleeve. The left and right bearing housings can also be interchanged. This allows for four cycles of use, increasing efficiency by four times, reducing production costs, and saving installation personnel the workload of disassembling and assembling the bearing housing arm sleeve, saving time and effort and reducing the labor intensity of workers.

[0021] like Figure 1 As shown, the first operating cycle involves wearing down wear surface A. When wear surface A is severely worn, the mounting boss 11 on the lower side of the bearing housing is placed in the mounting groove 51 for continued use. The second operating cycle will cause wear on wear surface B. When wear surface B is severely worn, this bearing housing is swapped with the bearing housing at the other end for continued use. The third operating cycle will cause wear on wear surface C. When wear surface C is severely worn, the mounting boss 11 on the lower side of the bearing housing is placed in the mounting groove 51. The fourth operating cycle will cause wear on wear surface D. After four operating cycles, the arm sleeve can be replaced.

[0022] Both ends of the bearing housing body 1 are fixed to the submerged roller support arm 5 by locking components 6; the locking components 6 include long studs 61 and locking nuts 62, with the locking nuts 62 installed at both ends of the long studs 61. The locking components 6 can reliably fix the bearing housing body 1 to the submerged roller support arm 5.

[0023] Further, considering the convenience of installation and maintenance, the left and right ends of the bearing seat body 1 are provided with installation openings 12, which are penetrated from the top surface to the bottom surface of the bearing seat body 1, and provide installation channels for long studs. Meanwhile, the installation openings are also provided at the two ends of the sink roll support arm. During installation, the long studs only need to enter the installation openings 12 and penetrate the entire installation openings 12, and then be locked by the lock nuts 62; without sequentially penetrating the sink roll support arm and the bearing seat body from top to bottom, the installation work of the sink roll bearing seat is greatly facilitated.

[0024] Further, the top surface and the bottom surface of the two ends of the bearing seat body 1 are provided with arc-shaped grooves 13, which are penetrated from the front side to the rear side of the bearing seat body 1, and the axis of the arc-shaped groove 13 is parallel to the axis of the bearing seat body 1.

[0025] The arc-shaped groove 13 is provided with a fixing column 7, and the fixing column 7 is provided with a bolt hole matched with the long stud. After the long stud penetrates the fixing column and is locked by the lock nut, the fixing column plays a key supporting role in the fixing process of the bearing seat body 1, and enhances the stability of the bearing seat body 1 after installation.

[0026] The top surface of the fixing column 7 is an arc surface matched with the arc-shaped groove 13, and the bottom surface of the fixing column is a plane. The arrangement of the arc surface enables the fixing column to maintain good contact and cooperation in the arc-shaped groove, and the plane bottom surface also facilitates the close connection with the long stud and the lock nut, further improving the stability and reliability of the entire structure.

[0027] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
