Several groups of threaded columns 13 are symmetrically arranged on both sides of the support base 10; side ears 21 are symmetrically arranged on both sides of the adjustable top seat 20, and screw holes 22 corresponding to the position and size of the threaded columns 13 and threadedly connected are opened on the side ears 21; the adjustable top seat 20 is connected to the support base 10 by the cooperation of the locking nut 30 and the threaded column 13, and the support base 10 and its top seat are provided. The bearing groove 11 with the same diameter as the fixed bearing 40 and a height less than the radius of the bearing 40 is opened on the surface, and the limiting rings 12 with the same spacing as the width of the bearing 40 are symmetrically arranged on both sides of the bearing groove 11, can play a preliminary positioning and limiting role for the bearing 40; through several groups of threaded columns 13 symmetrically arranged on both sides of the support base 10, and side ears 21 with screw holes 22 corresponding to the positions and sizes of the threaded columns 13 and threaded connections symmetrically arranged on both sides of the adjustable top seat 20, and the adjustable top seat 20 is connected to the support base 10 by using the locking nut 30 and the threaded column 13 to cooperate, so that the gap of the bearing seat can be adjusted according to actual needs, so as to better adapt to different installation and use scenarios, and ensure the stability of the installation of the bearing 40 and the reliability of the equipment operation.

[0030] Furthermore, the groove surface of the bearing groove 11 is provided with a wear-resistant and anti-slip ring 14. The wear-resistant and anti-slip ring 14 and the bearing groove 11 are an integrally formed structure. The wear-resistant and anti-slip ring 14 adopts a wear-resistant rubber ring with a thickness of 1-3 mm, so that the bearing 40 can reduce wear during installation and use, improve service life, and at the same time increase anti-slip performance to ensure stable operation of the bearing 40.

[0031] Specifically, fixed feet 15 are symmetrically provided at both ends of the support base 10, and each set of fixed feet 15 is provided with mounting holes 16, so that the entire bearing seat can be conveniently fixed and installed in the desired position, thereby improving the convenience and stability of installation.

[0032] Among them, a shock-absorbing gasket 17 is provided on the bottom surface of the support base 10. The shock-absorbing gasket 17 has the same bottom area as the support base 10. The shock-absorbing gasket 17 is a rubber gasket with a thickness of 0.5-2mm, which can effectively reduce the vibration and noise during the operation of the equipment and improve the operation stability and comfort of the equipment.

[0033] In addition, the limiting ring 12, the supporting base 10, and the adjustable top seat 20 are an integrally formed structure, and the thickness of each set of limiting rings 12 is 3-5 mm, which enhances the structural strength of the limiting ring 12, improves the limiting effect on the bearing 40, and ensures the stability and safety of the bearing 40 during use.

[0034] Working principle of the bearing seat with adjustable clearance:

[0035] First, place the bearing 40 in the bearing groove 11 opened on the top surface of the support base 10. The diameter of the bearing groove 11 is the same as the diameter of the bearing 40, and the height of the bearing groove 11 is less than the radius of the bearing 40, which can play a certain role in limiting the bearing 40. In addition, it is necessary to ensure that the bearing 40 is located between the limiting rings 12 symmetrically arranged on both sides of the bearing groove 11. The spacing between the limiting rings 12 on both sides is the same as the width of the bearing 40, which can further accurately position the bearing 40 and prevent it from shifting in the horizontal direction.

[0036] Then, pick up the adjustable top seat 20 and align the screw holes 22 on the side ears 21 symmetrically arranged on both sides of the adjustable top seat 20 with the threaded posts 13 symmetrically arranged on both sides of the support base 10. The screw holes 22 and the threaded posts 13 correspond in position and size to each other, so that the subsequent connection operation can be carried out smoothly.

[0037] Next, the adjustable top seat 20 is rotated to slowly descend along the threaded column 13 until the bearing groove 11 on the bottom surface of the adjustable top seat 20 is also tightly fitted with the bearing 40. The degree of descent of the adjustable top seat 20 can be flexibly adjusted according to actual needs to achieve a suitable gap adjustment effect;

[0038] Finally, the locking nut 30 is screwed onto the threaded column 13. Through the cooperation between the locking nut 30 and the threaded column 13, the adjustable top seat 20 is firmly connected to the support base 10, ensuring the stability of the entire bearing seat structure, so that the bearing 40 can work stably in the bearing seat with adjustable clearance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
