Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In this embodiment, the oil groove 2 is located inside the main body 1, and the oil hole 3 is located at the center of the oil groove 2 and penetrates the main body 1; there are four sets of positioning concave keys 4, which are respectively located at both ends of the main body 1; the positioning convex keys 5 are connected to the main body 1 to form an integral whole; the positioning concave keys 4 and positioning convex keys 5 can be easily matched with another set of bearing bushes; the positioning convex keys 5 and positioning concave keys 4 are positioned correspondingly and have the same width and thickness; there are two sets of liner plates 6, which are located inside and outside the main body 1 respectively; both sets of liner plates 6 and both sides of the main body 1 form a sandwich 7; the liner plates 6 and the main body 1 are integrally formed, and the sandwich 7 can be easily connected to the main body 1. Reinforcing ribs 8 and vertical reinforcing ribs 9 are installed; the horizontal reinforcing ribs 8 are arc-shaped and match the curvature of the main body 1. The horizontal reinforcing ribs 8 are fixedly installed in the interlayer 7, and the vertical reinforcing ribs 9 are fixedly connected between the horizontal reinforcing ribs 8. The horizontal reinforcing ribs 8 and vertical reinforcing ribs 9 form a grid. The horizontal reinforcing ribs 8 and vertical reinforcing ribs 9 can make the stress distribution of the main body 1 more stable and improve the bearing capacity of the bearing bush; the space between the horizontal reinforcing ribs 8 and vertical reinforcing ribs 9 in the interlayer 7 is filled with sound-absorbing cotton 11. The friction-reducing alloy layer 10 is formed by casting on the two sets of liner plates 6. The friction-reducing alloy layer 10 can avoid large friction between the bearing bush and the rotating shaft it contacts.
[0023] The working principle and usage process of this utility model are as follows: In actual use, the bearing bushes that are compatible with the two sets of positioning concave keys 4 and positioning convex keys 5 are installed at the corresponding contact positions of the sliding bearing and the journal using the current conventional installation method. Then, when the sliding bearing is running normally, the anti-friction alloy layer 10 between the corresponding rotating shaft and the bearing bush can ensure the smoothness between the rotating shaft and the bearing bush and avoid large friction. During use, if the bearing bush is subjected to relevant external forces, the horizontal reinforcing ribs 8 and vertical reinforcing ribs 9 in the interlayer 7 near the inner and outer sides of the main body 1 will play a load-bearing role and distribute the force on the main body 1. At the same time, the force on the main body 1 can be made into a grid-like contact surface with the main body 1 itself after passing through the horizontal reinforcing ribs 8 and vertical reinforcing ribs 9, making the force distribution more stable, improving the load-bearing effect of the bearing bush, and further improving the mechanical strength. During use, the sound generated by the bearing bush in contact with the rotating shaft can be reduced by the presence of sound-absorbing cotton 11, which can reduce the vibration frequency of the sound propagating outward, reduce the decibels, and achieve a silent effect.
