Linear Stage with Fold Back Drive782412:004.26
Drive relocated to the rear
The task of this customer-specific OEM development was to create a travel path of 150 mm in 250 mm installation space, in which the load is wider than long. The available installation space had to be completely filled with an aluminum base body in order to achieve the necessary rigidity.
Integrated ball screw with synchronous belt
The ball screw was integrated between the base body and the moving carriage plate. It was also moved downwards via a pair of synchronized pulleys with synchronous belts. The transmission error of this additional transmission element could be minimized by optimally adjusting the pre-stress, thereby resulting in only a slight increase in repeatability errors. A compromise also had to be reached on the guiding system with regard to the guiding relationship. The lateral distance between the carriages had to be greater than the distance between the carriages in the direction of travel. Less stringent requirements for straightness made that acceptable.
