PRODUCT OVERVIEW Circular systems Carriages

PRODUCT OVERVIEW CIRCULAR SYSTEMS Type CARRIAGES Type

PRODUCT DESCRIPTION Nadella AXNR circular module is a further development of Nadella FSR circular rails. AXNR module is a reliable and cost competitive solution. The product is based on the combination of standard components to allow product definition and availability in short time. Modification or special version to meet specific requirement are anyway possible. The Nadella AXNR circular system is composed of groups of standard elements: aluminium basement, guide rails and carriages, transmission by gearbox and toothed belt, lubrication units and carriage indexing for precise carriage...

SYSTEM CONFIGURATION 3.1 CIRCULAR RAIL FSRO AND FSRQ

SYSTEM CONFIGURATION CIRCULAR RAIL FSRO AND FSRQ Circular rails are induction hardened on raceway to achieve life and ground to improve surface finish and accuracy. Circular rails are composed of both circular and straight parts. When the systems dimensions become excessive for shipment in a preassembled unit alignment blocks provide a simple way to align the joints between two parts. In this case it’s convenient to ask for a short removable piece of rail to simplify the carriage insertion on the assembled unit (Option 13). FSRO circular rails in AXNRO Nadella circular module AXNRO is made...

SYSTEM CONFIGURATION CARRIAGES Carriages equipped with Nadella guide rollers supporting the load in all directions. Standard carriages with rollers in fixed position to allow precise movement in the round and in the stright section of the guide rail circuit. Carriage preload is set already in the factory for a ready to use product. The carriage is equipped with two concentric guide rollers and two eccentric guide rollers. The eccentric guide rollers are mounted on the inner side of the circuit and allow to set the preload. Normal preload is registered already in the factory for a ready to...

SYSTEM CONFIGURATION BASIC CONFIGURATION TRANSMISSION Carriage traction is based on toothed belt for silent and maintenance free transmission. Design focused to reduce the distance from the belt to the carriage in order to minimize the peak-load on the carriage connection at high speed during the transition from round to straight path. Carriage distance has to be a multiple of the belt pitch: 10 mm up to rail radius 300 mm and 20 mm for radius 400 and 500. The length of the module depends from the length of the belt. For carriages at constant pitch, the most common configuration, the belt...

3.3 ALUMINIUM ALLOY BASE The module basement is made in aluminium. It is composed by the main plates supporting the pulleys and the profiles to support the linear guide rails. It’s a compact solution that allows to save space in the equipment. For long modules it’s necessary to support the module to avoid excessive stress and deformation in the structure. The extruded profiles supporting the linear rails have T slots along their length used to fix options as lubricators and carriage indexing cam in any position. IDLER PULLEY Idler pulley is mounted on a slide to allow belt tensioning....
