All about Automation Hall 1, Stand 221
Dr. Tretter presents its extensive range of linear axes from the Product line "Movitec". For example, users can implement special solutions for positioning and handling tasks quickly and flexibly according to the modular principle. New in the range of ball screws is a version with steel housing for ball screw nuts.
With the Movitec axes, efficient and cost-effective solutions can be designed to reliably move medium loads. The basic profile of the components is made of drawn and anodized aluminum profiles as standard. There are also two steel guides integrated in the aluminum profile, as well as innovative guide carriages with built-in recirculating ball tracks. Depending on the application and the required rigidity, the systems are adjusted without backlash or preloaded.
The axes can be equipped with toothed belt or spindle drive. For drives with toothed belts, particularly long strokes and higher speeds can be implemented. The spindle drive works precisely, with repeatability and can absorb increased permissible axial loads. The loads and duty cycles determine the appropriate spindle design such as ball screw, coarse thread, round thread and trapezoidal threaded spindle. The linear axes in the 40, 60, 86 or 116 series can also be ordered with increased profile for larger load capacities.
In Essen, the manufacturer also shows his Ball Screwsconsisting of spindle, nut with the balls and storage. With high efficiency they convert the rotation of a motor into a linear motion. Therefore, these components are used as drive elements for all types of linear guides. The range includes the steel housing for ball screw nuts according to DIN (Form B). This serves as a connecting element between the drive and guide. The user can mount the ball screw drive easily and accurately.
New in the portfolio are the axial angular contact ball bearings. This allows ball screws in modern machine tools to be positioned quickly, efficiently and with very high accuracy. The BSBD series, for example, can accommodate high axial loads in both directions thanks to the double-row configuration with a pressure angle of 60 degrees. The bearings are sealed and delivered ready-to-install with lifetime lubrication.
