Description

TECHNICAL FIELD

[0001] The utility model relates to hot galvanizing technical field, concretely is a shaft bush with zinc sliding function. BACKGROUND

[0002] In the continuous hot galvanizing production process, the zinc pot equipment is one of the most important equipment in the hot galvanizing production line, and the zinc pot roller of the galvanizing line is an important component of the zinc pot equipment. In order to ensure the quality of hot galvanizing, the zinc pot roller of the galvanizing line must rotate at a uniform speed and be stable.

[0003] In the prior art, the shaft sleeve is fixed with the shaft head of the zinc pot roller of the galvanizing line. Since the zinc pot roller of the galvanizing line is entirely immersed in the molten metal solution at about 460 DEG C, the zinc liquid corrodes the roller, the bearing and the steel strip to produce zinc slag. The sliding bearing of the zinc pot roller of the galvanizing line is completely submerged in the molten zinc liquid, and the sliding bearing of the zinc pot roller of the galvanizing line is composed of the shaft sleeve and the bearing bush. Referring to the schematic diagram of the connection between the shaft sleeve and the bearing bush in the prior art, the existing shaft sleeve and bearing bush are in line contact. The zinc liquid can only be discharged to the two ends of the bearing bush at the moment before contact. There is a certain activity gap between the shaft sleeve and the bearing bush, so that the suspended slag in the zinc liquid is easily adhered to the surface of the bearing bush and the shaft sleeve of the sliding bearing. In addition, the dynamic viscosity coefficient of the aluminum-zinc liquid is equivalent to that of water. Under the action of the tens of tons of tensile force of the steel strip, the liner and the bearing bush of the sliding bearing of the zinc pot roller of the galvanizing line are basically in a boundary friction state at the contact surface, which easily causes the wear of the interface of the friction pair. The abrasive wear is caused by the zinc slag on the friction interface during the rotation of the sliding bearing, and different degrees of scratches or furrows are generated. When the shaft sleeve and the bearing are worn to a certain degree, they cannot be used any more. Figures 6-7 In the prior art, the shaft sleeve is fixed with the shaft head of the zinc pot roller of the galvanizing line. Since the zinc pot roller of the galvanizing line is entirely immersed in the molten metal solution at about 460 DEG C, the zinc liquid corrodes the roller, the bearing and the steel strip to produce zinc slag. The sliding bearing of the zinc pot roller of the galvanizing line is completely submerged in the molten zinc liquid, and the sliding bearing of the zinc pot roller of the galvanizing line is composed of the shaft sleeve and the bearing bush. Referring to the schematic diagram of the connection between the shaft sleeve and the bearing bush in the prior art, the existing shaft sleeve and bearing bush are in line contact. The zinc liquid can only be discharged to the two ends of the bearing bush at the moment before contact. There is a certain activity gap between the shaft sleeve and the bearing bush, so that the suspended slag in the zinc liquid is easily adhered to the surface of the bearing bush and the shaft sleeve of the sliding bearing. In addition, the dynamic viscosity coefficient of the aluminum-zinc liquid is equivalent to that of water. Under the action of the tens of tons of tensile force of the steel strip, the liner and the bearing bush of the sliding bearing of the zinc pot roller of the galvanizing line are basically in a boundary friction state at the contact surface, which easily causes the wear of the interface of the friction pair. The abrasive wear is caused by the zinc slag on the friction interface during the rotation of the sliding bearing, and different degrees of scratches or furrows are generated. When the shaft sleeve and the bearing are worn to a certain degree, they cannot be used any more.

[0028] Please refer to Figures 1-7 The present application provides a technical scheme: a bushing with zinc running function, comprising a bushing 1, three groups of wear-resistant ceramic tiles 2 mounted on the inner wall of the bushing 1.

[0029] The three groups of wear-resistant ceramic tiles 2 are arranged along the annular direction of the inner wall of the bushing 1, and the main zinc runner 3 is formed between every two adjacent wear-resistant ceramic tiles 2.

[0030] Three groups of mounting clamping grooves 5 are arranged on the inner wall of the bushing 1, and the wear-resistant ceramic tile 2 is integrally connected with a clamping block 6 on one side, and the clamping block 6 is adaptively connected in the mounting clamping groove 5. Specifically, the stable installation of the wear-resistant ceramic tile 2 is realized through the adaptive connection of the mounting clamping groove 5 and the clamping block 6, so that the wear-resistant ceramic tile 2 is convenient to disassemble and assemble, the maintenance cost is reduced, and the stability is improved.

[0031] A plurality of groups of auxiliary zinc flowing grooves 4 are equidistantly arranged on the surface of the wear-resistant ceramic tile 2 along the length direction thereof.

[0032] The wear-resistant ceramic tile 2 is coarsely ground on the side close to the inner wall of the bushing 1, and is polished on the side away from the inner wall of the bushing 1. Specifically, the coarsely ground side of the wear-resistant ceramic tile 2 is in contact with the inner wall of the bushing 1, the friction force of the coarsely ground side of the wear-resistant ceramic tile 2 is larger, the stability of the connection between the wear-resistant ceramic tile 2 and the bushing 1 is improved, and the polished side of the wear-resistant ceramic tile 2 is smoother, the polished side of the wear-resistant ceramic tile 2 is connected with the shaft, and the smoothness of the shaft movement is improved.
