They can be used in conditions where they can simultaneously withstand combined radial and axial loads. They are lightweight, corrosion resistant, and suitable for applications such as chemical, food, and precision machinery where there are special requirements for materials or loads.

[0003] Currently, some cages adopt an integrated structural design, which can ensure overall rigidity and stability to a certain extent, but has revealed significant drawbacks in actual use. When the cage needs maintenance due to wear, damage, or lubrication failure, the integrated structure makes it impossible to disassemble and replace the faulty part individually.

[0023] 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.

[0024] Example 1

[0025] Please see Figures 1-3 A plastic bearing cage for use in combined load environments includes an annular plate 1 and an annular plate 2 8, which are arranged vertically. The thickness of both annular plate 1 and annular plate 2 8 is 3.5 mm. Several arc-shaped notches 15 are opened at opposite ends of annular plate 1 and annular plate 2 8. A ball bearing 7 is provided between two arc-shaped notches 15. A bolt 12 is fixedly connected to the middle of the front side of the top end of annular plate 2 8. A knob sleeve 11 is threadedly connected to the outer wall of the bolt 12. The outer wall of the knob sleeve 11 is rotatably connected to the front side of the inner wall of annular plate 1. A sliding bolt 10 is fixedly connected to the middle of the rear side of the top end of annular plate 2 8. The outer wall of the sliding bolt 10 is slidably connected to the rear side of the inner wall of annular plate 1.

[0026] To further explain, when installing the ball bearing 7, first use a screwdriver to screw into the top of the knob sleeve 11, which has a cross groove. By rotating the knob sleeve 11, its inner wall slides upwards along the threaded surface of the bolt 12. During this process, the annular plate 1 moves upwards, and its other inner wall slides upwards in sync with the outer wall of the sliding bolt 10. Once the arc-shaped notches 15 on the inner walls of the opposite ends of the annular plate 11 and the annular plate 2 8 open to a suitable distance, the ball bearing 7 can be inserted between the arc-shaped notches 15 on both sides. Then, use the screwdriver to reverse the knob sleeve 11, causing it to slide downwards along the threaded surface of the bolt 12, which causes the bottom of the annular plate 11 to fit tightly against the top of the annular plate 2 8, thereby limiting the ball bearing 7 placed between the arc-shaped notches 15 and completing the installation. For subsequent maintenance, repeating the above operation will achieve quick disassembly, greatly improving maintenance efficiency.

[0027] Example 2

[0028] Please see Figures 4-5 Further, based on Embodiment 1, the inner wall of the annular plate 1 is provided with a transition groove 13 on one side of the arc-shaped notch 15, the inner wall of the annular plate 8 is provided with a transition groove 14 on one side of the arc-shaped notch 15, the inner wall of the annular plate 1 is provided with heat dissipation holes 4 on both sides of the transition groove 13, the inner wall of the annular plate 8 is provided with heat dissipation holes 9 on both sides of the transition groove 14, the inner wall of the transition groove 13 is fixedly connected with a connecting block 16, the inner wall of the transition groove 14 is fixedly connected with a connecting block 17, the inner heat dissipation plate 3 is fixedly connected to the inward end of the connecting block 16, the outer heat dissipation plate 2 is fixedly connected to the outer end of the connecting block 16, the inner heat dissipation plate 6 is fixedly connected to the inward end of the connecting block 17, the outer heat dissipation plate 5 is fixedly connected to the outer heat dissipation plate 5, the thickness of the inner heat dissipation plate 3 and the inner heat dissipation plate 6 is 1.5mm, and the thickness of the outer heat dissipation plate 2 and the outer heat dissipation plate 5 is 1.65mm.

[0029] To further explain, when annular plate 1 and annular plate 2 8 are combined to form a retainer, and then assembled with other parts, they constitute a complete bearing. During the bearing's use, the heat dissipation holes 1 4 and 2 9 opened on the inner walls of annular plate 1 and annular plate 2 8, respectively, can effectively increase the internal heat-receiving area and accelerate heat transfer. At the same time, the connecting blocks 1 16 and 2 17 embedded in the transition grooves 1 13 and 2 14, respectively, through the connecting action, make the outer heat dissipation plate 1 2 and inner heat dissipation plate 1 3 on the inner and outer sides of annular plate 1, as well as the outer heat dissipation plate 2 5 and inner heat dissipation plate 2 6 on the inner and outer sides of annular plate 2 8, tightly fit against the surface of the annular plate. This structure further expands the heat dissipation area, accelerates heat dispersion, significantly reduces the bearing's operating temperature, effectively avoids wear and performance degradation caused by high temperature, thereby greatly extending the service life of the retainer and improving the overall stability and reliability of the bearing.

[0030] The heat sink used above is made of copper, and its surface is electroplated to improve its corrosion resistance.

[0031] Working principle: First, use a screwdriver to snap the top of the knob sleeve 11 in place. Then, rotate the knob sleeve 11 so that the inner wall of the knob sleeve 11 rotates on the outer wall of the bolt 12, forming a threaded upward sliding motion, which drives the annular plate 1 to move upward. At the same time, the inner wall of the other side of the annular plate 1 slides upward against the outer wall of the sliding bolt 10 until the arc-shaped notches 15 on the inner walls of the opposite ends of the annular plate 1 and the annular plate 2 open a certain distance. Then, insert the ball bearing 7 between the arc-shaped notches 15 on both sides in sequence. Then, use the screwdriver to reverse the knob sleeve 11 so that it slides down the threaded outer wall of the bolt 12, causing the bottom of the annular plate 1 to fit against the top of the annular plate 2, limiting the ball bearing 7 placed between the arc-shaped notches 15, thus completing the installation of the ball bearing 7. For subsequent maintenance, simply use the screwdriver to rotate the knob sleeve 11 and repeat the above steps to complete the disassembly for maintenance.

[0032] After the retainer formed by the merging of annular plate 1 and annular plate 2 is assembled with the remaining parts, a complete bearing is obtained. During the use of the bearing, the heat dissipation holes 4 and 9 opened in the inner walls of annular plate 1 and annular plate 2 respectively will increase the heat-receiving area inside annular plate 1 and annular plate 2. Then, through the connecting block 16 and connecting block 2 17 embedded in the transition groove 13 and transition groove 2 14 respectively, and through the connecting action of connecting block 16 and connecting block 2 17, the outer heat dissipation plate 2 and inner heat dissipation plate 3 on the inner and outer sides of annular plate 1, and the outer heat dissipation plate 5 and inner heat dissipation plate 6 on the inner and outer sides of annular plate 2, respectively, come into contact with the surfaces of annular plate 1 and annular plate 2, further increasing the heat-receiving area, improving the heat dissipation effect, and extending the service life of the retainer.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
