Roller conveyor forward rotation resistance and the resistance of belt conveyor main drag accounted for 50% to 85%. The captain of the belt conveyor over 80m total resistance calculation formula, the total resistance by factors such as the length of the conveyor according to the selected charge coefficient, the rotating part of the quality associated with the installation and operating conditions of roller bearing branches per unit length, the return tray parameters on the rotating part of the mass per unit length of the roller, simulated coefficient of friction, conveyor length, special friction roller forward major resistance and friction tape cleaner special additional resistance, the conveyor belt unit mass, transport of materials per unit mass, etc.
Usually roller bearings mounting space is limited. In most cases, the shaft diameter (or roller bearing diameter) is based on the mechanical design or other design constraints. Therefore, roller bearing type and size selection is based on the inner diameter of the roller bearing of the decision. Thus, the standard roller bearing main dimensions table are based on the international standard diameter size Commission.
Size scale form roller bearing range of mechanical devices designed in the best use of scale roller bearing (this design to the roller bearing is easy to purchase, where it aside, some models of the inlet roller bearing catalog on indeed, but some non-standard roller bearing is no spot in mainland China, sometimes futures will be very long, so the roller bearing selection to consider the time and cost of capital late replacement) roller bearing load is applied the load on the roller bearing, the nature, size, the direction is changing. Typically, the basic load ratings are displayed on the size of the table. But axial load and radial load, etc., also select the appropriate roller bearings important factor. When the needle roller and ball bearings the size of proportionality, needle roller bearings usually have high load capacity and withstand greater vibration and shock loading.
