[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a support bearing for the inner drum of a fully automatic drum washing machine. The device mainly consists of an inner ring 1, rolling elements 2, and an outer ring 3. The connecting disc 4 on the outer ring 3 is typically manufactured using a one-piece molding process in actual production. This one-piece molding method involves precision casting or machining to produce the outer ring 3 and the connecting disc 4 as a single unit. Compared to welding and other connection methods, one-piece molding significantly improves overall strength, effectively avoids stress concentration points and potential weld defects caused by welding, and thus ensures that the component can stably withstand forces from all directions during long-term use.

[0022] A cage is typically installed between the rolling element 2 and the outer ring 3 and inner ring 1. The main function of the cage is to evenly separate the rolling elements 2, prevent them from colliding with each other, ensure that the rolling elements 2 can roll smoothly, and maintain the relative positional relationship between the rolling elements 2 and the inner ring 1 and outer ring 3, thereby improving the operational accuracy and stability of the entire device. Since the installation of a cage is a common technique in related technical fields and is not the core innovation of this patent, it will not be elaborated on here.

[0023] The connecting disc 4 has a sliding groove 5 inside, and the machining accuracy of this groove 5 directly affects the smoothness of the sliding of the subsequent connecting parts 8. High-precision turning is typically used to machine the groove 5, ensuring that the surface roughness of the groove 5 meets a certain standard to reduce friction during the sliding of the connecting parts 8. Multiple connecting parts 6 are distributed on the surface of the connecting disc 4, each with an adjustment hole 7 connecting to the sliding groove 5. The positions of the adjustment holes 7 are precisely designed and calculated to meet different installation requirements. Simultaneously, a positioning groove 11 is provided within the sliding groove 5 corresponding to the position of each adjustment hole 7. The shape and size of the positioning groove 11 are closely fitted to the connecting parts 8, and its machining accuracy is also required to ensure the stability of the connecting parts 8 after installation.

[0024] The connecting plate 4 is slidably connected to multiple connectors 8 via a sliding groove 5. Each connector 8 includes a bolt 12, a fixing hole 10, and multiple screw holes 9. The bolt 12 is made of high-strength alloy steel and undergoes a special heat treatment process to improve its strength and toughness, ensuring it will not deform or break under stress during long-term use. During installation, the connector 8 with the bolt 12 removed is first inserted into the sliding groove 5. A certain clearance exists between the sliding groove 5 and the connector 8; this clearance is precisely designed to ensure smooth sliding of the connector 8 while preventing wobbling due to excessive clearance. The connector 8 slides along the sliding groove 5 to the corresponding connecting part 6, simultaneously fitting into the positioning groove 11. During fitting, it is essential to ensure that the connector 8 and the positioning groove 11 are completely fitted without any looseness or misalignment. Then, the depth of the connector 8 inserted into the sliding groove 5 is adjusted according to actual usage requirements. This adjustment process requires the use of professional measuring tools, such as calipers, to ensure accuracy. After adjusting to the appropriate position, insert the bolt 12 into the corresponding adjusting hole 7 and thread it into the screw hole 9. To further improve the stability and reliability of the connection, multiple screw holes 9 can be provided, with multiple bolts 12 passing through the adjusting hole 7 and threaded into the screw hole 9. When tightening the bolt 12, operate according to a certain torque standard, using tools such as a torque wrench to ensure that the tightening degree of each bolt 12 is consistent, thereby forming a stable connection structure between the connector 8 and the connecting plate 4.

[0025] The dimensions of connector 8 perfectly match those of positioning groove 11. This precise dimensional matching is achieved through rigorous manufacturing processes and quality control. During the manufacturing of connector 8 and positioning groove 11, each dimensional parameter is strictly controlled to ensure that the tolerance between them is within an extremely small range. This design makes connector 8 more stable after installation, effectively reducing wear and malfunctions caused by shaking or displacement during use.

[0026] By adjusting the depth of the connector 8 inserted into the positioning groove 11, the length of the extending fixing hole 10 can be precisely controlled. In practical applications, the installation positions and connection dimensions of washing machine outer tubs of different models and sizes vary. This device design allows for flexible adjustment of the position of the fixing hole 10, enabling accurate connection with washing machine outer tubs of different sizes. During connection, first, based on the actual dimensions of the washing machine outer tub, measure and calculate the required extension length of the fixing hole 10. Then, adjust the position of the connector 8 as described above to ensure accurate alignment of the fixing hole 10 with the corresponding mounting hole on the washing machine outer tub. Finally, securely connect the two using bolts or other connection methods.

[0027] Each connecting part 6 has at least two adjustment holes 7. During actual installation, different adjustment holes 7 can be selected to install the connector 8 according to the specific size of the washing machine drum. This design further enhances the adaptability of the device, meeting the installation needs of washing machine drums of various sizes. For example, when encountering a smaller washing machine drum, the adjustment hole 7 near the center of the connecting plate 4 can be selected to install the connector 8; while for a larger washing machine drum, the adjustment hole 7 away from the center of the connecting plate 4 can be selected, thus achieving precise adaptation to washing machine drums of different sizes.

[0028] The diameter of the adjusting hole 7 is greater than or equal to that of the threaded hole 9, and there are no threads inside the adjusting hole 7. This design allows the bolt 12 to pass smoothly through the adjusting hole 7, while the threaded part at the other end of the bolt 12, being larger than the diameter of the adjusting hole 7, cannot pass through it. During installation, this design feature ensures that after the bolt 12 passes through the adjusting hole 7, it can effectively fix the connector 8 to the connecting plate 4, preventing the connector 8 from falling off or shifting during use.

[0029] The support bearing, as a whole, connects to the inner drum of the washing machine and is installed inside the machine. During installation, first ensure the inner drum is correctly positioned, then tightly connect the inner ring 1 of the support bearing to the inner drum. Connection methods such as interference fit or key connection can be used to ensure synchronous rotation between the inner ring 1 and the inner drum, preventing relative slippage. After installation, the entire support bearing system must undergo comprehensive testing and adjustments, including smooth operation and noise testing, to ensure it functions properly and meets the washing machine's usage requirements.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
