Abstract

The present invention relates to a device 10 for mining mineral raw materials or roadheading (tunnelling) roadways or tunnels, having at least one rotatable driven tool 1 which is superimposed by impacts. The device 10 can be used especially for mining hard rock such as platinum ore and has a sleeve 6 supported rotatably in a casing in whose sleeve boring is mounted an eccentric shaft 4. This is joined at one end of the eccentric shaft 4 to the tool 1, and mounted rotatably eccentrically to the sleeve axis and about the eccentric shaft axis ME. The device has a drive, whose drive shaft is coupled to the sleeve 6 and a mechanism for introducing a rotation into the eccentric shaft 4. This mechanism comprises according to the present invention a cycloid drive 20 arranged outside the sleeve 6 whose input and output shaft comprises the eccentric shaft 4. The cycloid drive 20 has in one embodiment a cam disc 7 with a cycloid outer circumference 8, torsionally fixed to the eccentric shaft 4, which circulates in an outer ring 11, which is provided with concentrically arranged roller bodies 12 as outer rollers. By the rolling movement of the cam disc 7 against the outer ring 11 the cam disc 7 is displaced about its own axis when the sleeve 6 is rotating and hereby the eccentric shaft 4 is also rotated at a reduced speed about its own axis ME.
