Structure design and stress analysis of a marine palletizer based on tapered roller bearing

Palletizer is a kind of equipment commonly used for material transfer, which is often used in ports and warehouses. With the development of shipping industry, the demand for marine palletizer is also urgent. This paper designed a kind of marine material palletizer based on tapered roller bearings, which solved the problem that the palletizer was easy to get stuck under inclined working conditions. Its function was verified by mechanical analysis and FEM simulation. The results showed that compared with the traditional stacker, the stacker with this structure could reduce the tangential force on the roller of the rotary device by 50%, and greatly improved the operation stability of the stacker under the inclined working condition at sea.
