  • Standard roller conveyors carry rollers with 50 mm diameter (50 mm roller) and a roller pitch of about 75 mm and more. The roles are ever made of plastic or metal. Roller conveyors are stationary systems in conveyor technology that move piece goods through an arrangement of rollers.
  • the belt touches the rollers tangentially.

  • a more or less large bias of the belt is required depending on the belt used and torque to be transmitted.
  • the belts must either be shortened to the required length on site and welded together, or additional deflection rollers and complex tensioning devices must be used if prefabricated drive belts with a predetermined length are to be used. It should be noted that only a few traction devices can be shortened to the desired length and that the quality of the weld on site can only be ensured with difficulty.
  • the transmission element must always be very tight and be re-tensioned regularly. If the tension is too low, it can lead to strong vibrations or skip the teeth on the toothed discs. Too high forces cause a heavy load on the bearings and the belt and negatively affect the gear components due to wear. In addition, high forces, high stiffness of the belts, a variety of belt deflections and / or the use of slide rails lead to heavy loss friction, wear and unnecessary energy loss.

In addition, a frictional operation often leads to wear and premature failure of components of the roller conveyors.
