Description

Technical Field

[0001] This utility model relates to the field of ceramic coating bushing technology, and in particular to a wear-resistant and corrosion-resistant bushing based on a ceramic coating. Background Technology

[0002] Ceramic-coated wear-resistant and corrosion-resistant bushings are devices that coat the surface of a substrate with a ceramic coating, exhibiting excellent wear resistance and corrosion resistance. These bushings are typically made of ceramic materials, possessing high hardness, high wear resistance, and good chemical stability, enabling them to perform exceptionally well in harsh working environments.

[0003] The utility model patent with publication number CN218480055U discloses a ceramic bushing for automobiles. By setting rubber buffer block one and rubber buffer block two, a buffer space can be formed between bushing one and bushing two. When bushing one and bushing two are compressed, rubber buffer block one and rubber buffer block two will shrink, thereby achieving the effect of reducing vibration force. At the same time, the ceramic material bushing can enhance the wear resistance of the surface.

[0004] However, it lacks the ability to disassemble ceramic bushings separately, and its disassembly and assembly flexibility is generally limited. After the ceramic bushings wear out, they need to be completely disassembled and replaced, resulting in high usage and maintenance costs. The connection between the ceramic bushing and the shaft is also not very flexible, and wear is more likely to occur between the bushing and the shaft. Therefore, we need to upgrade and modify the existing technology to overcome the existing problems and shortcomings. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant and corrosion-resistant bushing based on a ceramic coating to solve the problems mentioned in the background art.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has a ceramic shell, an upper mounting base, an outer sealing ring, an upper protrusion, a ceramic inner shell, a lower mounting base, and an inner sealing ring. The upper and lower mounting bases are used to insert and assemble the two sets of shells. The upper and lower protrusions cooperate to limit the upper and lower positions of the movable sleeve.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1As shown in Figure 5, this embodiment provides a wear-resistant and corrosion-resistant bushing based on a ceramic coating, including a device body 1. The device body 1 includes a ceramic outer shell 2, a ceramic inner shell 3, a reinforcing rib 4, and a movable sleeve 5. The ceramic outer shell 2 is fitted over the outer side of the ceramic inner shell 3 from top to bottom. The reinforcing rib 4 is installed in the gap between the ceramic outer shell 2 and the ceramic inner shell 3. The movable sleeve 5 is installed inside the ceramic inner shell 3. Four sets of fixing holes 8 are correspondingly opened at the lower ends of the ceramic outer shell 2, the ceramic inner shell 3, and the reinforcing rib 4. Fixing bolts 9 are connected in the fixing holes 8. Two sets of through holes 6 are correspondingly opened at the upper ends of the ceramic outer shell 2, the ceramic inner shell 3, and the reinforcing rib 4. Sealing bolts 7 are screwed into the through holes 6.

[0027] In this embodiment, the upper end of the ceramic outer shell 2 is provided with an upper mounting base 21 and an upper protrusion 25 is provided on the inner ring of the upper mounting base 21; the lower end of the ceramic inner shell 3 is provided with a lower mounting base 31 and a lower protrusion 34 is provided on the inner side of the lower mounting base 31; an outer sealing ring 22 is provided at the bottom of the ceramic outer shell 2 and is attached to the lower mounting base 31; an inner sealing ring 32 is provided at the top of the ceramic inner shell 3 and is attached to the upper mounting base 21; a corrosion-resistant layer 23 is provided on the outer wall of the ceramic outer shell 2; and the ceramic outer shell 2 is located on the corrosion-resistant layer. The outer side of the 23 is coated with a wear-resistant layer 24. The two sets of housings are connected and assembled by the upper mounting base 21 and the lower mounting base 31. The upper protrusion 25 and the lower protrusion 34 cooperate to limit the upper and lower positions of the movable sleeve 5. The ceramic outer shell 2 is protected by the corrosion-resistant layer 23 and the wear-resistant layer 24, which improves the weather resistance of the housing. It can realize the free separation and assembly of the bushing, which is convenient for the independent disassembly of the bushing and the movable sleeve 5, and is convenient for maintenance or replacement. The operation is simple and convenient, which improves the practicality and convenience of the device.

[0028] In this embodiment, four sets of vertical rods 41 are provided on the reinforcing rib 4, and a fixing seat 42 is provided at the bottom of the reinforcing rib 4 and the vertical rods 41. The vertical rods 41 facilitate the increase of the longitudinal bearing capacity of the reinforcing rib 4, and the fixing seat 42 facilitates the fixing of the reinforcing rib 4 between the ceramic outer shell 2 and the ceramic inner shell 3, thereby improving the overall strength and stability of the bushing.

[0029] In this embodiment, a plurality of ball bearings 51 are movably mounted on the movable sleeve 5. A guide rod 52 is provided on the outer wall of the movable sleeve 5, and a guide groove 33 is provided on the inner wall of the ceramic inner shell 3. The guide rod 52 and the guide groove 33 slide in correspondence. The ball bearings 51 facilitate the sliding placement of the movable sleeve 5 inside the ceramic inner shell 3. The guide groove 33 and the guide rod 52 provide vertical sliding guidance for the movable sleeve 5, thereby enabling a sliding connection between the bushing and the shaft. This effectively reduces frictional damage and noise between the shaft and the bearing seat, while also reducing wear on the shell. The movable sleeve 5 has low maintenance and replacement costs, thus improving the practicality of the device.

[0030] The working principle and process of this utility model are as follows: In use, the movable sleeve 5 is inserted into the inner side of the ceramic inner shell 3 through the guide groove 33 and the guide rod 52. A reinforcing rib 4 is fitted onto the outer side of the ceramic inner shell 3. Finally, the ceramic outer shell 2 is fitted onto the outer side of the ceramic inner shell 3 and fixedly connected through the fixing hole 8 and fixing bolt 9. In use, the bushing is installed inside the shaft seat, and the external rotating shaft is connected to the inside of the movable sleeve 5. During rotation, the shaft can rotate within the ball bearing 51, which can drive the movable sleeve 5 and the ball bearing 51 to slide within the ceramic inner shell 3, giving the shaft a certain lateral movement space and reducing pressure and wear on the shaft. When wear occurs inside the bushing, the ceramic outer shell 2 and the ceramic inner shell 3 can be disassembled and separated using the fixing bolt 9, and the movable sleeve 5 can be removed from the inside. This facilitates independent replacement of the two sets of shells or the movable sleeve 5, eliminating the need to replace the entire bushing and achieving better cost savings.
