Background

In the continuous hot galvanizing production process, zinc pot equipment is one of the most important equipment in a hot galvanizing production line, and zinc pot rollers of a galvanizing line are important components in the zinc pot equipment. In order to ensure the quality of hot galvanizing, the galvanized wire zinc pot roller needs to stably rotate at a constant speed.

In the prior art, the bearing bush is arranged on the roller arm, and forms a sliding bearing with the shaft sleeve arranged on the roller shaft head of the galvanized wire zinc pot, and because the galvanized wire zinc pot roller is wholly soaked in molten metal solution at about 460 ℃, the roller arm has larger thermal deformation, the roller arm is repeatedly used, the installation precision of the bearing bush is not high, and the concentricity of the bearing bushes at two sides is poor. Referring to the accompanying drawings 1-2 of the specification, the connection diagram between the galvanized wire zinc pot roller 1, the shaft head 2, the shaft sleeve 3 and the shaft sleeve base body 4 in the prior art is that a certain gap exists between the shaft sleeve base body 4 and the shaft sleeve 3, and the traditional shaft sleeve base body 4 and the shaft sleeve 3 are in line contact, so that the shaft sleeves 4 at the two ends of the galvanized wire zinc pot roller 1 are easily caused not to be in the same axis direction, and the shaft head 2 and the shaft sleeve 3 bear huge torque under the combined action of huge tensile force of strip steel and the non-concentric shaft sleeves 4 in the moving process of the galvanized wire zinc pot roller 1, and the shaft head 2 is easily broken, so that huge economic loss is caused.

In view of this, a V-shaped bearing bush structure is now devised.
