[0002] A spherical plain bearing is a spherical sliding bearing with a variety of special process treatments, such as surface phosphating, flanging, padding, spraying, etc., to meet different mechanical movement requirements. The main feature of a spherical plain bearing is that its sliding contact surface consists of an inner spherical surface and an outer spherical surface, which allows it to rotate and swing at any angle during movement.

[0018] Embodiment 1:
[0019] As Figures 1-4As shown in the figure, the utility model provides a fiber-wound spherical plain bearing structure, which includes a mounting seat 1. A bearing seat 2 is fixedly connected to the top of the mounting seat 1. An outer ring 3 is fixedly connected to the inner surface of the bearing seat 2. An inner ring 4 is arranged on the inner surface of the outer ring 3. Heat dissipation through holes 7 are arranged inside the inner ring 4. A first through hole 8 is arranged on the top of the bearing seat 2. A second through hole 9 is arranged on the top of the outer ring 3. Mounting slots 6 are formed on the outer surface of the bearing seat 2. A heat dissipation device 5 is arranged on the outer surface of the bearing seat 2. The heat dissipation device 5 includes a U-shaped clamping seat 51. A positioning card strip 52 is fixedly connected to the inner surface of the U-shaped clamping seat 51. A bent connecting plate 53 and a temperature sensor 54 are fixedly connected to the outer surface of the U-shaped clamping seat 51. One end of the bent connecting plate 53 away from the U-shaped clamping seat 51 is fixedly connected to a connecting housing 55. A driving motor 56 is fixedly connected to the inner surface of the connecting housing 55. A heat dissipation blade 57 is fixedly connected to the output shaft of the driving motor 56.
[0020] Specifically, the heat dissipation through holes 7 are arranged in a circular pattern along the outer surface of the inner ring 4, and the heat dissipation blades 57 are directly opposite to the heat dissipation through holes 7.
[0021] Specifically, the first through hole 8 is arranged directly above the second through hole 9, and the inside of the first through hole 8 is communicated with the inside of the second through hole 9.
[0022] Specifically, the mounting slots 6 are symmetrically arranged on both sides of the bearing seat 2, and the inner surface of the mounting slots 6 is in extrusion fit with the outer surface of the positioning card strip 52.
[0023] Specifically, the outer surface of the temperature sensor 54 is in contact with the outer surface of the bearing seat 2, and the temperature sensor 54 is electrically connected to the driving motor 56.
[0024] The working principle and beneficial effects of the above embodiments.
[0025] During use, the positioning card strip 52 of the heat dissipation device 5 is installed into the mounting slot 6 on the bearing seat 2, so that the heat dissipation device 5 is installed on the bearing seat 2, and the temperature sensor 54 is in contact with the bearing seat 2. When the heat generated by friction during the working process of the spherical plain bearing exceeds a certain threshold, the temperature sensor 54 transmits a signal to the driving motor 56, so that the driving motor 56 drives the heat dissipation blades 57 to rotate. The airflow generated by the heat dissipation blades 57 blows towards the heat dissipation through holes 7, and at the same time, it also speeds up the air flow rate around the outer ring 3 and the inner ring 4, so as to accelerate the heat dissipation of the outer ring 3 and the inner ring 4, improving the heat dissipation effect of the spherical plain bearing. Through the provided first through hole 8 and second through hole 9, lubricating oil is injected from the first through hole 8, passes through the second through hole 9 and then flows into the gap between the outer ring 3 and the inner ring 4, thereby reducing the wear between the outer ring 3 and the inner ring 4.
