ABSTRACT:
In an apparatus for the displacement of bearing blocks mounted on carriages which support shafts, a first carriage is carried for displacement in a carriage guideway fixed to the frame, and the other carriage is carried in a carriage guideway of the first carriage, these two carriage guideways being mutually parallel. To allow the carriages to be displaced with sufficient accuracy without expensive control devices, two spindle screw nuts designed as toothed belt pulleys are mounted in the first carriage parallel to each other and freely rotatable, and the screw spindles screwed into them are mounted selectively for free rotation and for being fixed, on the one hand in the machine frame and, on the other hand, in the second carriage. In the first carriage there is mounted a further drive belt pulley that is drivable by a motor and securable by a securing device, this further drive belt pulley driving an endless toothed belt that drives said spindle screw nuts designed as toothed belt pulleys.
