473 carrier rollers // general information General information about carrier rollers Guide for selecting your carrier rollers 1. The following specifications must be defined before selecting the carrier rollers: description of application goods being conveyed (l x w x h) weight (distributed load, point load) environmental factors (e.g. humidity, temperature, dust) gravity-driven or power-driven carrier roller conveying velocity electrostatic charge 2. Selecting the carrier rollers: material of the carrier rollers diameter of the tube and the axle model / type of bearing type of mounting / type of axle end type and design of drive (fixed drive, accumulating drive) installation length (EL) available accessories available coatings optional special construction Key information about type and design of drive Functionality of an accumulating conveyor roller There is no solid connection between the drive element and the roller body. The constant drive force is implemented using only the friction within a slide bushing located between these two components. When the conveyed goods accumulate in a position, the roller body stops and the drive component continues to run. Once the stop function is re-activated, all rollers start to turn and the conveyed goods resume movement. Caution: The take-along force depends on the goods being conveyed and their weight (coefficient of friction: 5-7% of the weight of the conveyed goods), the support points and any lubricants in use. Pre-tensioning the round belt The tension-mounted round belt provides the drive power for the rollers. The initial tension on the round belt is -10% of the center distance between the center drive shaft and carrier roller axle. In addition: You should take into account that a static charge on the rollers can occur when non-electrically conductive bearing bases are used. This could then lead to a discharge spark between the roller and the frame. Axle finishing process external thread internal thread spring axle flat spanner flat INFO
