[0022] In order for those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.

[0023] The utility model discloses a bearing with stability bearing seat.

[0024] Referring to Figures 1-3 A bearing with stability bearing seat, including bearing body 3 and bearing seat body 2, the upper end front side of bearing seat body 2 is provided with mounting hole, bearing body 3 is fixedly installed in the inside of mounting hole, the lower surface of bearing seat body 2 is provided with bottom plate 1, the upper surface of bottom plate 1 is fixedly provided with bolt 4, the both ends of bearing seat body 2 are provided with through hole, the upper end of bolt 4 passes through through hole, the upper end of bolt 4 is threadedly sleeved with hexagonal nut 5, the lower side of hexagonal nut 5 is in abutment with bearing seat body 2, the both sides of the upper end of bearing seat body 2 are fixedly provided with fixed frame 6, movable rod 7 is slidably arranged in the inside of fixed frame 6, the lower end of movable rod 7 is fixedly provided with hexagonal collar 8, limit block 13 is fixedly sleeved on the upper end of movable rod 7, try to prevent movable rod 7 from slipping out of movable frame 6, the lower end of movable rod 7 is provided with avoiding slot, try to prevent movable rod 7 from interfering with bolt 4, hexagonal collar 8 is in abutment with the outside of hexagonal nut 5, the upper end of movable rod 7 is provided with cavity, the inside of cavity is provided with the limit mechanism that restricts movable rod 7 movement.

[0025] Referring to Figures 1-3 The limit mechanism includes stop block 9 and stop rod 10, stop block 9 is slidably arranged in the inside of cavity, stop rod 10 is fixedly arranged on one side of stop block 9, one end of stop rod 10 extends to the outside of cavity, through hole is formed in the side wall of fixed frame 6 and corresponds to stop rod 10, one end of stop rod 10 passes through through hole, spring 12 is fixedly arranged on the side of stop block 9 away from stop rod 10, the other end of spring 12 is fixedly connected with the inner wall of cavity, which facilitates the reset of stop block 9.

[0026] Referring to Figures 1-3 The upper side of one end of stop rod 10 away from stop block 9 is provided with threaded hole, threaded long rod 11 is threadedly sleeved in the inside of threaded hole, which can limit the movement of stop rod 10, and can determine whether threaded long rod 11 is loose by the height of threaded long rod 11.

[0027] The utility model discloses a bearing seat limiting nut, which is characterized by comprising a bearing seat main body 2, a bearing main body 3, a bottom plate 1, a bolt 4, a hexagonal nut 5, a movable rod 7, a hexagonal sleeve ring 8, a stopper 9, a stopper rod 10 and a threaded long rod 11.

[0028] When the device runs and generates vibration, the conventional bearing seat limiting nut is prone to loosening, but in the utility model, even if the hexagonal nut 5 has a tendency to rotate due to vibration, the hexagonal sleeve ring 8 tightly wraps it, limiting the rotation of the hexagonal nut 5. At the same time, the stopper 9 always maintains a pushing force on the stopper rod 10 under the elastic force of the spring 12, so that the stopper rod 10 continuously limits the movement of the movable rod 7, ensuring that the hexagonal sleeve ring 8 is always stably wrapped on the hexagonal nut 5, effectively preventing the hexagonal nut 5 from being separated from the bolt 4 due to long-term vibration, ensuring the stability of the connection between the bearing seat and the bearing, and further ensuring the normal operation of the device. In addition, by observing the position of the threaded long rod 11, it can be directly judged whether the stopper rod 10 has been displaced, and indirectly judged whether the entire limiting structure is working normally, so that potential problems can be found in time.
