In the form of a belt conveyor rollers varied, according to the function of the main drive roller and bend pulley two. Drive mode according to the minutes, the drive roller is divided into an outer and inner-drive-drive. External-drive is the drive unit placed outside the drive pulley, gear reducer directly with the associated input shaft roller. The drive type is all on the drive gear inside the drum, which is commonly referred to as electric drum, usually for short distances and lower power single drive places.
As the prisoners for structural belt conveyors easily damaged, so the general welfare board using the hub cast into one structure when overloaded, and between the drum shell and administer the use of dry plates are then connected. Roller bearings are usually spherical roller bearings, in order to have better fatigue resistance. The expansion sets generally more frequent use of the ring expansion sets.
The main drive roller is applied to the conveyor belt conveyer traction, usually a plastic surface of the drum, i.e., the surface is covered with rubber or the like, this will help increase the coefficient of driving friction between the rollers and the conveyor belt, to improve the driving force of the roller circumference, When working conveyor belt to prevent slippage between the roller shaft and hub expansion sets usually ring coupling structure.
Idler pulleys are generally used to change the direction of conveyor belt conveyor belt conveyor, conveyor belt does not exert a driving force. Smooth drum is commonly used to facilitate rotation to reduce friction and reduce unnecessary friction losses, the roller shaft hub connection structure generally preclude the use key. Idler pulleys are also a variety of types, including redirecting roller conveyor ends, the tension roller guide device and increase the wrap angle of the drive roller guide roller and so on.
Drum formal structure with magnetic levitation conveyor belt conveyor roller structure similar to an ordinary, so the drive pulley and bend pulley can refer to the choice selected by ordinary belt conveyor.
Maglev belt conveyors are a flexible multi-body systems, the need to establish the appropriate flexible multibody system dynamics model of its analysis, modeling and analysis before making the knowledge you need to understand the main points of the flexible multi-body system dynamics theory.
Conveyor belt this complex flexible multibody systems, due to the characteristics of flexible conveyor itself cause too much uncertainty of its model, but in its modeling, solid modeling all of the components are based on a rigid structure modeling, it needs to be discrete geometry conveyor into many small pieces of flexible belt unit with block and with constraints between blocks by applying an appropriate, flexible conveyor belt and then the block unit consists of dynamic analysis. For the purposes of the conveyor belt conveyor, which in itself is a flexible body, which does not belong to the material hosted on its own structural quality of its components, and this will lead to inertia loads conveyor and its motion due to gravity material generated to produce corresponding vibration in the analysis must be based on this dynamic load characteristic to select the appropriate mode to analyze the deformation of the belt.
