The invention relates to a device ( 1 ) for the variable setting of the control times of gas-exchange valves of an internal combustion engine, with a driving element ( 12 ), with a driven element ( 8 ) and with an adjusting gear ( 11 ) designed as a triple-shaft gear, the driving element ( 12 ) being mounted rotatably with respect to the driven element ( 8 ) on the latter or on the camshaft ( 9 ). The relative phase position of the driven element ( 8 ) with respect to the driving element ( 12 ) can be selectively varied or held by means of the adjusting gear ( 11 ). According to the invention, it is proposed to mount the driving element ( 12 ) on the driven element ( 8 ) by means of rolling bearings ( 19, 21 ). Radial and/or axial forces can thereby be supported in an optimized way in terms of friction, as a result of which the efficiency of the device ( 1 ) is increased.
