Description

Technical Field

[0001] The utility model belongs to the technical field of bearing installation, and in particular relates to a structure for facilitating replacement of a bearing seat. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Bearings can support mechanical rotating bodies and reduce friction. Where there are bearings, there are support points. The inner support point of the bearing is the shaft, and the outer support point is the support seat. With the advancement of the times, various types of bearing seats have appeared on the market, but most bearing seats have relatively single functions. When the bearing model is incorrect, the bearing needs to be replaced, but most bearing seats are not convenient for replacing bearings. When the bearing is installed in the bearing seat, long-term movement will cause the steel balls in the bearing to wear and the bearing needs to be replaced, but most of them disassemble the bearing and then replace the steel balls, which is very inconvenient. Moreover, when the bearing is rotating, the steel balls may fall off due to the long rotation time, and the bearing seat is installed on the ground. Long-term movement may cause the bolts to fall off, causing the bearing seat to leave the ground.

[0003] To this end, a bearing seat with a bulletin number of "CN210484419U" is provided, which is convenient for replacing bearings, and includes a bearing shell, a bearing outer wall and a ball. The lower left end of the bearing shell is movably connected to the bearing seat base, the lower end of the bearing seat base is provided with a first groove, the lower right end of the bearing shell is welded to the first connecting block, the bearing outer wall is in contact with the outer end of the roller, the middle of the bearing outer wall and the bearing inner wall is provided with a ball, the outer side of the bearing inner wall is fixedly connected to the second connecting block, the left and right ends of the bearing seat base are movably connected to the fixing bolt, and the lower side of the bearing seat base is provided with a fixed base, the left and right ends of the fixed base are provided with a third groove, and the upper end of the fixed base away from the third groove is welded to the fixed block. Thus, the problem of inconvenience in replacing bearings and steel balls, inability to reduce the falling of steel balls, and inability to strengthen the fixing of the bearing seat is solved.

[0004] However, for the above-mentioned bearing seat that is easy to replace bearings, although the left end of the bearing shell and the bearing seat base form a rotating structure, and the right end of the bearing shell and the bearing seat base are connected by a snap-fit ​​connection, which is convenient for opening and closing the bearing shell and the bearing seat base, the following obvious defects still exist during use: However, the clamping and fixing surfaces of the bearing shell and the bearing base for the bearing are arc-shaped planes. Since no corresponding limiting components are set for the bearing, it is easy for the bearing to rotate due to resonance due to the rotation of the inner ring and the rotating shaft, which will cause the bearing component to vibrate and fall off from the bearing shell and the bearing base.
