Description

[Technical field]

[0001] The utility model relates to the technical field of bearing bushes, in particular to a high-strength bearing bush. [Background technology]

[0002] The characteristics of the bearing material are: small friction coefficient, sufficient fatigue strength, good running-in and good corrosion resistance. Common bearing materials include bearing alloy (Babbitt alloy), copper alloy, powder metallurgy, gray cast iron and wear-resistant cast iron. It is the contact part between the sliding bearing and the journal. It is a semi-cylindrical surface in the shape of a tile. It is very smooth and is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering plastics or rubber. The existing bearings are as follows:

[0003] For example, the patent publication number CN210919830U discloses a bearing with strong wear resistance, including a bearing body, a connecting ring is provided at the top of the bearing body, a positioning groove is provided at the top of the connecting ring, a connecting hole is provided on the side of the positioning groove, a bearing inner groove is provided on the side of the bearing body, a lubrication hole is provided inside the bearing inner groove, a lubricating liquid is provided inside the lubrication hole, an oxide film is provided on the top of the lubricating liquid, a friction-reducing layer is provided on the outer surface of the bearing inner groove, a first alloy layer is provided at the bottom end of the friction-reducing layer, and a tungsten carbide layer is provided at the bottom end of the first alloy layer. The friction between the bearing and the sliding bearing is reduced by the provided friction-reducing layer, the lubricating liquid and the positioning groove, and the heat generated is reduced. At the same time, the high-temperature resistant coating coated on the outer surface reduces the influence of heat on the bearing, thereby achieving the purpose of improving wear resistance. The lubrication hole, the oxide film and the lubricating liquid enable the lubricating liquid to fully lubricate the entire bearing inner groove, thereby achieving the purpose of full lubrication.

[0004] Although the above utility model can fully lubricate the lubricating liquid into the inner groove of the bearing, the following problems still exist: although the above bearing is made of a variety of wear-resistant materials and can prevent itself from being easily damaged, the bearing is generally connected to some accessories through bearings, such as drive shafts, and some accessories will vibrate during operation. The vibration will cause the connection of some bearings to be unstable, and in severe cases, they will fall off, which will cause the bearing to be unable to be used normally. [Contents of the utility model]

[0008] The two lead screws are respectively threadedly connected to the first bearing bush and the second bearing bush;

[0009] The connecting blocks are respectively fixedly connected to the lead screws, and the connecting blocks on the two lead screws are arranged opposite to each other;

[0010] The ball is rotatably connected to the connecting block, and one end of the ball can be in contact with an external shaft. The first bearing bush and the second bearing bush are both provided with bearing grooves for the bearings to be placed therein.

[0025] like Figures 1 to 2 A high-strength bearing bush includes: a bearing bush 1 and a bearing bush 2 corresponding to the bearing bush 1, wherein the bearing bush 1 and the bearing bush 2 are connected by screws.

[0026] It also includes: two lead screws 3, a connecting block 4 and a ball 5;

[0027] The two lead screws 3 are threadedly connected to the bearing bush 1 and the bearing bush 2. The rotation of the lead screw 3 can drive the connection block 4 welded and fixed to the lead screw 3 to move, and the connection block 4 drives the ball 5 rotatably connected to the connection block 4 to move, so that the ball 5 contacts the transmission shaft, thereby fixing the transmission shaft. The ball 5 is mainly used to reduce the friction between the connection block 4 and the transmission shaft.

[0028] A bearing groove 6 for receiving the bearing is provided on the bearing shell 1 and the bearing shell 2, thereby reducing the deviation of the transmission shaft during rotation.

[0029] Specifically, since several arc-shaped connecting rings 7 are fixedly connected to the bearing 1 and the bearing 2, and reinforcing ribs 1 8 are fixedly connected between the connecting rings 7, the connecting rings 7 and the reinforcing ribs 1 8 are mainly used to increase the strength of the bearing 1 and the bearing 2.

[0030] Specifically, since a chamber 9 is provided on the connecting ring 7 and the reinforcing rib 8, an oil outlet hole 10 is provided on the bearing shell 1 and the bearing shell 2, one end of the oil outlet hole 10 is communicated with the chamber 9, and an oil inlet hole 15 communicated with the chamber 9 is provided on the reinforcing rib 8, and a sealing plug 11 is threadedly connected to the oil inlet hole 15. By opening the sealing plug 11 and injecting oil into the oil inlet hole 15, the oil enters the oil outlet hole 10 through the oil inlet hole 15 and the chamber 9, thereby realizing the oil filling of the bearing and the shaft through the oil outlet hole 10.

[0031] Specifically, the second reinforcing rib 12 is fixedly connected to the connecting ring 7 , and the strength of the connecting ring 7 is increased by the second reinforcing rib 12 .

[0032] Specifically, since the bearing 2 is fixedly connected to the fixed base 13, the fixed base 13 is rotatably connected to the bolt 14, and the bolt 14 is threadedly connected to the external equipment, the fixing effect of the bearing 1 and the bearing 2 is increased.

[0033] Specifically, the inner wall of the bearing groove 6 is inclined, thereby facilitating the positioning and fixing of the bearing.

[0034] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
