[0002] Bearings are an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Ball bearings are a type of rolling bearings, consisting of an outer steel ring, an inner steel ring, alloy steel balls and a bearing seat. They use rolling to reduce friction during power transmission and improve the transmission efficiency of mechanical power.

[0003] Currently, ball bearings need to be used in conjunction with bearing seats. The bearings are clamped in the inner ring by connecting the upper and lower bearing seats, and are fixed with bolts on both sides of the bearing seats. However, if the bolts on one side of the existing bearing seat are rusted or cannot be disassembled, the entire bearing seat cannot be disassembled, and the entire bearing seat needs to be destroyed, affecting the reuse of the bearing seat. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a shaft seat and a bearing; the bearing is arranged in the middle part of the shaft seat, and mounting frames are fixedly connected on both sides of the shaft seat, and bolts are threadedly connected on the mounting frames. A piston cylinder is arranged on one side of the shaft seat, and a first hydraulic piston and a second hydraulic piston are slidably connected inside the piston cylinder. One end of the first hydraulic piston is rotatably connected with a threaded connection, a locking ring is slidably connected inside the shaft seat, and one end of the second hydraulic piston is fixedly connected to the locking ring, and one side of the two locking rings are respectively pressed against the outer wall of the bearing through the shaft seat.

[0006] Preferably, an extension piece is fixedly connected to the outer end of the bolt, a threaded hole matching the bolt is formed on the outer wall of the mounting frame, and the outer wall of the bolt is threadedly connected in the threaded hole.

[0007] Preferably, the inner end of the bolt is fixedly connected with a rotating head, one end of the first hydraulic piston is provided with a rotating groove matching the rotating head, and one end of the rotating head is inserted into the rotating groove.

[0008] Preferably, a through groove is provided on the inner side of the shaft seat, and the locking ring is located in the through groove.

[0009] Preferably, guide blocks are fixedly connected to both ends of the locking ring, a guide groove is provided inside the shaft seat, the guide groove is communicated with the through groove, and one end of the guide block is inserted into the guide groove.

[0010] Compared with the prior art, the beneficial effect of the utility model is that when the bolt pushes the first hydraulic piston to move, the liquid added between the first hydraulic piston and the second hydraulic piston pushes the second hydraulic piston to move to the right, so that the two locking rings fix the bearing on the shaft seat, changing the previous bolt fixing method. Only one of the bolts needs to be removed to remove the bearing from the shaft seat. The situation where the bearing cannot be removed due to one bolt being damaged will not occur, thereby improving the service life of the bearing and the shaft seat. At the same time, the hydraulic locking method can buffer the bearing. BRIEF DESCRIPTION OF THE DRAWINGS
