When choosing conveyor drum, many factors need to be considered including the load of the item (the lightest and the heaviest), the shape and characteristics of goods, the design and condition of the bottom of goods , delivery speed, roller bearing is static load or dynamic load, environment (humidity, temperature, corrosive chemicals, clean rooms, etc.), static electricity’s effects on the goods and environment, conveyor is electric or no-power.
The main factors are affecting the carrying capacity of the conveyor drums, including shell, shaft, and bearing, and are determined by the weakest of them. Beyond the limit of the load will cause the conveyor drum become excessive bending, causing irreversible permanent deformation, so that the transport becomes unstable. Insufficient strength of shaft will lead to changes in bearing’s stress status, thus affecting the service life of the bearing. Overload will greatly reduce the service life of the bearing. When selecting the drum, it is also necessary to consider other factors such as the height error of conveying surface after the drum is assembled and the local stress during loading and unloading. The mechanical properties of steel tube and stainless steel are similar in bearing capacity, and they are generally considered to have the same bearing capacity when used. In general, increasing the wall thickness can only enhance the resistance ability of the shell, and it has little influence on the bearing capacity of the conveyor drum.
