ABSTRACT:
In order to improve a spindle drive for machine tools, comprising a housing, a spindle mounted in the housing, a drive motor arranged on the housing and a gear arranged in the housing and comprising an intermediate shaft driven by the drive motor and mounted in the housing via two shaft bearings spaced from one another as well as a first gear wheel seated on the intermediate shaft, wherein for driving the spindle as C-axis the first gear wheel engages in a first position with a second gear wheel driving the spindle so as to mesh with the second gear wheel without clearance, such that it is more simple in construction it is suggested that the first shaft bearing fix the intermediate shaft immovably on the housing in a direction transverse to its axis and that the intermediate shaft be adapted to be moved back and forth by the second shaft bearing relative to the second gear wheel in an adjusting direction between the first position and a second position, the gear wheels meshing with one another in the second position with clearance.
