Detailed Implementation

[0021] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0022] according to Figure 1-8 As shown, a high wear-resistant, pressure-resistant, and silent universal wheel includes a wheel frame 1. Wheel grooves 11 are provided on the outer walls of the front and rear sides of the wheel frame 1. Rollers 2 are rotatably installed in the wheel grooves 11. Several sets of balls 3 are installed on the top wall of the wheel grooves 11. A fixing component is installed at the axis of the rollers 2. Wear-resistant rings 4 are installed around the rollers 2.

[0023] In this embodiment, the top wall of the wheel groove 11 is an annular structure that matches the support platform 21. Several sets of mounting grooves 12 are evenly arranged on the top wall of the wheel groove 11. The mounting groove 12 is a semi-circular groove 24 that matches the ball 3. A fixing ring 5 is installed in the wheel groove 11. The side wall of the fixing ring 5 is in close contact with the top wall of the wheel groove 11. Several sets of limiting holes 51 are evenly arranged on the fixing ring 5. The ball 3 is installed in the mounting groove 12 one by one. The two ends of the fixing ring 5 are fixedly connected to the bottom end of the wheel frame 1 by screws. The diameter of the limiting hole 51 gradually decreases from the outside to the inside as the diameter of the ball 3 decreases, thereby restricting the ball 3 from falling out.

[0024] In this embodiment, a support platform 21 is provided on the side of the roller 2 near the wheel frame 1. The support platform 21 has a cylindrical structure and an arc-shaped groove 22 is provided at the end of the support platform 21. A mounting platform 23 is provided on the side of the support platform 21 near the wheel frame 1. A silent bearing 6 is fixedly installed on the mounting platform 23. The roller 2 is mounted on the wheel frame 1 through the silent bearing 6. The arc-shaped groove 22 abuts against the bottom end and the bottom side of the ball bearing 3. The ball bearing 3 reduces the friction between the roller 2 and the wheel frame 1, thereby reducing the noise generated by the caster when moving, and increasing the support area of ​​the wheel frame 1 for the roller 2, thereby enhancing the pressure resistance and load-bearing capacity of the caster.

[0025] In this embodiment, the fixing component includes a fixing shaft 7, which is mounted on the wheel frame 1. The rollers 2 are mounted on both sides of the fixing shaft 7. Thrust bearings 8 are fitted on both sides of the fixing shaft 7. A groove 24 is provided on the outer side wall of the rollers 2, and the thrust bearings 8 are mounted in the groove 24. One end of the fixing shaft 7 is provided with a screwing part 71, and the other end of the fixing shaft 7 is provided with a threaded part 72. A fixing nut 9 is installed on the threaded part 72 through a threaded engagement. The fixing shaft 7 passes through the rollers 2 and the wheel frame 1 in sequence. Under the action of the fixing nut 9 and the fixing shaft 7, the connection between the rollers 2 and the wheel frame 1 is made more secure, thereby reducing the noise generated by the vibration of the components of the caster and further improving the quietness of the caster when moving.

[0026] In this embodiment, the wear-resistant ring 4 is preferably made of wear-resistant rubber, and the outer side wall of the roller 2 is provided with a number of anti-detachment platforms 25. The wear-resistant ring 4 is snapped onto the roller 2 through the anti-detachment platforms 25.

[0027] In use, the roller 2 is mounted on the wheel frame 1 with the cooperation of the silent bearing 6. The arc groove 22 at the end of the support platform 2 abuts against the ball bearing 3. The ball bearing 3 reduces the friction between the roller 2 and the wheel frame 1, thereby reducing the noise generated by the caster when moving. It also increases the support area of ​​the wheel frame 1 for the roller 2, thereby enhancing the pressure resistance and load-bearing capacity of the caster. The wear-resistant ring 4 protects the roller 2, thus extending the service life of the caster. In addition, the connection between the roller 2 and the wheel frame 1 is made more secure by the clamping and fixing of the fixed shaft 7 and the fixed nut 9, thereby reducing the noise generated by the vibration of various components of the caster and further improving the quietness of the caster when moving.
