2083049 9118224 PCTABS00008 In order to achieve a compact spindle drive which is also lightweight and consisting of few components, and where the drive motor (8) is mounted in a stationary manner in relation to the spindle drive, the spindle drive according to the invention is configured with two sets of bevel gears comprising a first larger pair of gears (11, 13) and a second smaller pair of gears (12, 14). The spindles (15, 17) can hereby be mounted in star formation in the housing and alternately enter into engagement with the first gear (11) and the second gear (12), and thus alternately rotate the one way and the other way. At the same time, all of the spindles (15, 17) are suspended in the same plane, whereby a very uniform machining operation is achieved. Finally, the housing can be provided with a turning motor (21), which via a pinion (2, 19) can revolve the housing (1) at the same time that the spindles rotate.
