Description

Technical Field

[0001] This utility model belongs to the field of roller shaft sleeve technology, specifically a composite coated roller shaft sleeve integrated structure that is corrosion-resistant and fatigue-resistant. Background Technology

[0002] At present, most hot-dip galvanizing units for strip steel adopt submerged roller devices, which mainly consist of submerged rollers, stabilizing rollers and their components set in the zinc liquid. The submerged rollers are immersed and corroded in the molten zinc liquid at 450-480°C. At the same time, the strip steel drives the submerged rollers and stabilizing rollers to rotate at a running speed of 35-180m / min.

[0003] In actual use, since the submerged roller and stabilizing roller are passively rotated under the action of the strip steel, and cannot be installed with rolling bearings with a low coefficient of friction, only sliding bearings can be used. Therefore, the requirements for the bushings are higher. Not only are the strength requirements high, but they must also not jam with the sliding bearings.

[0004] Therefore, this utility model provides an integrated structure for a composite coated roller shaft and bushing that is corrosion-resistant and fatigue-resistant. Utility Model Content

Through the above structure, the device can be fixed in a designated position according to the required requirements, thereby increasing the operational stability of the device.

[0010] Preferably, the sliding rod is fixedly connected to the rotating shaft on its side wall, and the rotating shaft is fixedly connected to the sliding rod on its side wall. With the above structure, the device can work according to requirements by replacing components of different sizes, thus increasing the practicality of the device.

[0011] Preferably, the rotating shaft, fixed rod, and sliding rod are made of high-strength steel.
