NTN-SNR has developed a completely new series (Figure 1.1) of standard axes with the AXE linear axes. The main features of this series are: • Short delivery time • Cost-optimized design • Single axis and axis systems including accessories configurable online • Light and high rigid aluminum profiles as base • Maximum protection of the guiding systems placed inside the profile against pollution and damages • Unchanged high quality level • Optimum ease of maintenance and service • I ndividual axis configurations through a wide range of available fastening elements and accessories for the...

The base profile assumes the guiding rails of the linear guides. The linear guides are screwed to the profile (Figure 1.2). The base profile is of anodized aluminum, which largely determines the stiffness of a linear axis. Figure 1.2____ Profile with screwed linear guide The slider unit is a complex assembly group usually consisting of an aluminum profile or aluminum components. The carriages of the guiding system are mounted on the slider unit. The slider unit also compounds the drive elements with the guiding elements of a linear axis. On its upper side the slider unit is provided with...

Drive systems The SNR AXE linear axes series are equipped with toothed belt drive, which makes them suitable for fast handling and positioning applications. All linear axes are equipped with AT or STD toothed belt drives. These are extruded polyurethane belts with integrated steel cords. The AT toothed belt drives are of zero-gap shape. Using black toothed belts prevents discoloration of the toothed belts under UV - radiation. These toothed belts have the following features: • Low wear • Maintenance free • High tensile strength and low elongation • High precision – pitch error ± 0,2mm/m •...

Adjusting the toothed belt tension for SNR linear axes by a radially moveable defecting pulley (Figure1.8). Setting the correct toothed belt tension with theSNR measuring device, which is equipped with a force sensor to adjust the exact toothed belt tension (Figure 1.9) Figure 1.8____ Toothed belt tension Bild 1.9______ Measuring device for the toothed belt tension As a result, there will be no risk of overloading the toothed belt or pulley bearing due to excessive toothed belt tension. Furthermore, centered alignment will ensure optimum driving characteristics and low wear. Advantages •...

Selection criteria Selection of the drive element Toothed belt drive Toothed belt / Ω drive Preliminary selection of the size Description of the static load of the the guiding system Determining of the equivalent static load of the the guiding system Check-up of the static load capacity of the the guiding system Description of the dynamic load of the the guiding and drive system Determining of the equivalent dynamic load of the the guiding system Check-up of the dynamic load capacity / life time of the guiding system Description of the maximum system deformation Determining of the system...

Linear axes are pre-finished units with a combination of precise guiding and driving elements. Thereby linear axes and their variations are cost efficient and extremely compact components for machines and systems, which can be mounted and put into operation within the shortest time. Criteria for the selection of linear axes could be as follows: For the selection of SNR linear axes our sales and application engineers with years of experience will also be glad to assist you. 2.2 Declaration of incorporation for partly completed machinery (Machinery directive 2006/42/EG) The manufacturer SNR...
